These flaps are supplied by a perforating artery issued from the deep peroneal artery or the posterior tibial artery, and the chainlinked adipofascial neurovascular axis around the sural/saphenous nerve. It is a versatile and reliable technique for soft-tissue reconstruction of the heel and ankle region with 180-degrees rotation. In this paper, we present its developing history, vascular basis, surgical techniques including flap design and elevation, flap variations in pedicle and component, surgical indications, and illustrative case reports with different perforating vessels as pivot points for foot and ankle coverage.展开更多

The three-dimensional (3D) gait measurement was conducted by using a 3D infrared multi-camera system anda force plate array to record the Ground Reaction Forces (GRF) and segmental motions simultaneously. The ankle-foot complexwas modelled as a four-segment system, connected by three joints: talocrural joint, sub-talar joint and metatarsophalangeal joint.The subject-specific joint orientations and locations were determined using a functional joint method based on the particleswarm optimisation algorithm. The GRF moment arms and joint moments acting around the talocrural and sub-talar joints werecalculated over the entire stance phase. The estimated talocrural and sub-talar joint locations show noticeable obliquity. Thekinematic and kinetic results strongly suggest that the human ankle-foot complex works as a mechanical mechanism with twodifferent configurations in stance phase of walking. These lead to a significant decrease in the GRF moment arms therebyincreasing the effective mechanical advantages of the ankle plantarflexor muscles. This reconfigurable mechanism enhancesmuscle effectiveness during locomotion by modulating the gear ratio of the ankle plantarflexor muscles in stance. This studyalso reveals many factors may contribute to the locomotor function of the human ankle-foot complex, which include not only itsre-configurable structure, but also its obliquely arranged joints, the characteristic heel-to-toe Centre of Pressure (COP) motionand also the medially acting GRF pattern. Although the human ankle-foot structure is immensely complex, it seems that itsconfiguration and each constitutive component are well tuned to maximise locomotor efficiency and also to minimise risk ofinjury. This result would advance our understanding of the locomotor function of the ankle-foot complex, and also the intrinsicdesign of the ankle-foot musculoskeletal structure. Moreover, this may also provide implications for the design of bionicprosthetic devices and the development of humanoid robots.展开更多

In ...Cutaneous nerve injury is the most common complication following foot and ankle surgery. However, clinical studies including long-term follow-up data after cutaneous nerve injury of the foot and ankle are lacking. In the current retrospective study, we analyzed the clinical data of 279 patients who underwent foot and ankle surgery. Subjects who suffered from apparent paresthesia in the cutaneous sensory nerve area after surgery were included in the study. Pa- tients received oral vitamin B^2 and methylcobalamin. We examined final follow-up data of 17 patients, including seven with sural nerve injury, five with superficial peroneal nerve injury, and five with plantar medial cutaneous nerve injury. We assessed nerve sensory function using the Medical Research Council Scale. Follow-up immediately, at 6 weeks, 3, 6 and 9 months, and 1 year after surgery demonstrated that sensory function was gradually restored in most patients within 6 months. However, recovery was slow at 9 months. There was no significant difference in sensory function between 9 months and 1 year after surgery. Painful neuromas occurred in four patients at 9 months to 1 year. The results demonstrated that the recovery of sensory func- tion in patients with various cutaneous nerve injuries after foot and ankle surgery required at least 6 months.展开更多

This study aimed to assess the health status of OM patients with war-related ankle-foot injuries.Methods: A total of 1129 veterans with ankle-foot injuries participated in a case-control study(2014–2016). Thirty patients with chronic OM of the ankle-foot were compared with 90 non-OM participants as the control group. Quality of life(QOL), life satisfaction and the ability to perform basic and instrumental activities of daily living were measured using the following questionnaires: short-form health survey(SF-36), satisfaction with life scale(SWLS), activity of daily living(ADL) and instrumental activity of daily living(IADL), respectively. OM patients were categorized according to their risk factors as A, B and C hosts using a modified version of the Cierny and Mader classification system. The one sample t-test, 2-independent sample t-test, ANOVA, Pearson correlation coefficient and multiple linear regression analyses were applied to analyze the data.Results: Ankle-foot pain leading to surgery(P <0.001) and orthosis usage(P =0.039) were more common in OM patients. There was no significant difference between the two groups in the prevalence of pulmonary and cardiovascular diseases or kidney failure and other related diseases. OM patients showed a significantly lower level of mental health compared to non-OM respondents(P=0.025). Approximately, 70.0% of ankle-foot injured veterans were dissatisfied with their life, and there was no difference between the two groups(P>0.05). Mobility was significantly lower in the OM patients than in the control group(P=0.023). Life satisfaction(P=0.001) and the ability to perform daily activities were the determinants for poor physical(P=0.018) and mental health-related quality of life(P=0.012). According to the Cierny and Mader classification system, they were all included in the type C host classification, with one major and/or three or more minor risk factors.Conclusion: A low level of quality and satisfaction of life and ability to perform activities of daily living were observed in OM patients with war-related ankle-foot injuries. Surgeries of the ankle and foot due to pain were much more common in OM patients than in non-OM participants. Since all the participants were classified as the C-host, health policy planning seems to be necessary.展开更多

Ankle injuries are among the most commonly diagnosed injuries in the game. The result is reduced physical activity and endurance levels, lost game time, and considerable medical cost. Sports medicine professionals must employ the correct diagnostic tools and effective treatments and rehabilitation protocols to minimize the impact of these injuries on the player. This review examines the diagnosis, treatment, and postoperative rehabilitation for common football injuries of the ankle based on the clinical evidence provided in the current literature.展开更多

If not treated properly, recurrent sprains can lead to a condition of chronic ankle instability (CAI). The present paper examines some subjects with a previous history of acute inversion ankle sprain who have developed a subsequent condition of instability, grouping them according to inclusion criteria and analyzing them through four field tests considered objective by the scientific literature: SEBT test, BEES test, TIBT test, SHT test. The data obtained were stored in order to compare them following a re-education protocol aimed at improving proprioception, balance, walking and strengthening the extrinsic and intrinsic muscles of the foot. per year. The subjects were then divided into two categories: subjects with CAI > 1 year and subjects with CAI ≤ 1 year. A protocol lasting 6 weeks was administered to both groups, trying to work on improving balance in single stance, improving static and dynamic stability, strengthening the gluteus medius and maximus (pelvis stabilizers) and strengthening of the intrinsic muscles of the foot. At the end of the protocol the subjects were all re-evaluated with the same field tests used previously and the data obtained were compared both with the pre-protocol data and with the data measured by the control subjects.展开更多

However, the scope of such disorders may expand months or even years after the trauma. Orthotic treatment as a rehabilitation process aims to enable people with disabilities to reach and maintain their optimal physical, sensory, intellectual, psychological, and social functional levels. This study aimed to investigate the rate of using orthoses among Iranian veterans with neuromuscular and skeletal disorders of the ankle and foot. Furthermore, the priorities of orthotic treatment in those veterans were explored.Methods: This qualitative study was a national health needs assessment conducted in 11 provinces of Iran during 2011–2016. A stakeholder research group was established to survey the veterans in respect to their demographic variables, activities of daily living, current health conditions, and rate of using orthoses.Results: Overall, 907 of the 1124 veteran participants completed the survey(response rate: 80.7%). Most of the veterans were men(97.7%), and their age and disability rate were 52.07±8.13 years and 31.92%±14.93%, respectively. Nearly 42% of the veterans had experience in using orthoses on a daily and weekly basis. As physical ambulation was the main problematic activity in veterans, most of them were using medical shoes and foot orthoses. Nearly 37% of veterans were in need of some type of lower limb orthoses on the contralateral side to compensate for their hip inequality. In sequential order, the most in need orthoses for veterans were foot orthoses(n=538), medical shoes(n=447), lower limb orthoses on the contralateral side(n=320), spinal orthoses(n=273), and upper limb orthoses(n=86).Conclusion: In spite of the high demands for orthoses among Iranian veterans with ankle and foot disorders, the use of orthoses is insufficient. Hence, there is a discrepancy between the current rate of orthoses use and its ideal situation, and more resources should be provided for service providers to be able to serve veterans. Moreover, veterans should be educated regarding orthoses, their use, and their impacts on the user's health status. The findings of a needs assessment of orthoses can be used in strategic planning and decision making to improve health care services for Iranian veterans.展开更多

文摘Optical imaging in the second near-infrared(NIR-II;900-1880 nm)window is currently a popular research topic in the field of biomedical imaging.This study aimed to explore the application value of NIR-II fluorescence imaging in foot and ankle surgeries.A lab-established NIR-II fluorescence surgical navigation system was developed and used to navigate foot and ankle surgeries which enabled obtaining more high-spatial-frequency information and a higher signal-to-background ratio(SBR)in NIR-II fluorescence images compared to NIR-I fluorescence images;our result demonstrates that NIR-II imaging could provide higher-contrast and larger-depth images to surgeons.Three types of clinical application scenarios(diabetic foot,calcaneal fracture,and lower extremity trauma)were included in this study.Using the NIR-II fluorescence imaging technique,we observed the ischemic region in the diabetic foot before morphological alterations,accurately determined the boundary of the ischemic region in the surgical incision,and fully assessed the blood supply condition of the flap.NIR-II fluorescence imaging can help surgeons precisely judge surgical margins,detect ischemic lesions early,and dynamically trace the perfusion process.We believe that portable and reliable NIR-II fluorescence imaging equipment and additional functional fluorescent probes can play crucial roles in precision surgery.
文摘There is controversy in the literature on where to place the tourniquet(thigh,calf,ankle)for foot and ankle surgery.While some authors prefer the ankle tourniquet to the calf tourniquet,others state that the surgeon can decide between using the thigh tourniquet or the ankle tourniquet,since there was no difference in postoperative pain between them.Where to place the tourniquet during foot and ankle surgery to cause the least possible postoperative pain to the patient as a result of the tourniquet is a common question in clinical practice.The reality is that,unfortunately,there is no consensus on this issue.Perhaps the only possible way to answer this question would be to conduct a comparative study with sufficient statistical power to reach scientifically sound conclusions.It does not seem easy to carry out such a study,but it would be important to be able to answer the question posed in the title of this Editorial once and for all.
文摘BACKGROUND The study investigates the connection between academic productivity and industry earnings in foot and ankle orthopedic surgery fellowships.Utilizing metrics like the H-index and Open Payments Database(OPD)data,it addresses a gap in understanding the relationship between scholarly achievements and financial outcomes,providing a basis for further exploration in this specialized medical field.AIM To elucidate the trends between academic productivity and industry earnings across foot and ankle orthopedic surgery fellowship programs in the United States.METHODS This study is a retrospective analysis of the relationship between academic productivity and industry earnings of foot and ankle orthopedic surgery fellowships at an individual faculty and fellowship level.Academic productivity was defined via H-index and recorded from the Scopus website.Industry earnings were recorded from the OPD.RESULTS Forty-eight foot and ankle orthopedic surgery fellowships(100%of fellowships)in the United States with a combined total of 165 physicians(95.9%of physicians)were included.Mean individual physician(n=165)total life-time earnings reported on the OPD website was United States Dollar(USD)451430.30±1851084.89(range:USD 25.16-21269249.85;median:USD 27839.80).Mean physician(n=165)H-index as reported on Scopus is 14.24±12.39(range:0-63;median:11).There was a significant but weak correlation between individual physician H-index and individual physician total life-time earnings(P<0.001;Spearman’s rho=0.334)and a significant and moderate positive correlation between combined fellowship H-index and total life-time earnings per fellowship(P=0.004,Spearman’s rho=0.409).CONCLUSION There is a significant and positive correlation between academic productivity and industry earnings at foot and ankle orthopedic surgery fellowships in the United States.This observation is true on an individual physician level as well as on a fellowship level.

文摘Cable-driven ankle–foot exoskeletons have attracted numerous researchers over the previous decade.The assistive forces of most exoskeletons pulled the back bottom of the shoes,across talocrural and subtalar joints.The talocrural joint is inherently mediolateral unstable at the plantarflexion position due to its sliding mortise structure,while the subtalar joint allows inversion/eversion.In this paper,a biologically inspired cross-type double-cable-driven ankle–foot exotendon was proposed to assist not only the plantarflexion moment but also the movement stability.The novel structure was bio-inspired by the behind-calf anatomically symmetric layout and under-foot cross-configuration of the ankle–foot muscles.To examine the combined functions,we conducted a forward pelvis perturbed standing experiment on five subjects without and with exotendon assistance and recorded the biomechanical data.Compared to the unpowered condition,the biological ankle plantarflexion moment was reduced by 39 with 0.1 Nm/kg exotendon assistance for one leg.Besides,the forward margin of stability was increased by 17 during the late perturbation period,which indicated the improvement of balance in the sagittal plane.In addition,the standard deviation of the lateral CoP and three-dimensional marker trajectories for the ankle condylar and heel all descended,which provided evidence for ankle–foot stability improvement.The results suggested that the proposed biological exotendon can provide the compound ankle–foot assistance,reducing plantarflexion moment and improving movement stability.

文摘Distally based perforator sural flaps from the posterolateral or posteromedial lower leg aspect are initially a neurofasciocutaneous flap that can be transferred reversely to the foot and ankle region with no need to harvest and sacrifice the deep major artery. These flaps are supplied by a perforating artery issued from the deep peroneal artery or the posterior tibial artery, and the chainlinked adipofascial neurovascular axis around the sural/saphenous nerve. It is a versatile and reliable technique for soft-tissue reconstruction of the heel and ankle region with 180-degrees rotation. In this paper, we present its developing history, vascular basis, surgical techniques including flap design and elevation, flap variations in pedicle and component, surgical indications, and illustrative case reports with different perforating vessels as pivot points for foot and ankle coverage.

文摘The objective of this study is to investigate the biomechanical functions of the human ankle-toot complex during the stancephase of walking. The three-dimensional (3D) gait measurement was conducted by using a 3D infrared multi-camera system anda force plate array to record the Ground Reaction Forces (GRF) and segmental motions simultaneously. The ankle-foot complexwas modelled as a four-segment system, connected by three joints: talocrural joint, sub-talar joint and metatarsophalangeal joint.The subject-specific joint orientations and locations were determined using a functional joint method based on the particleswarm optimisation algorithm. The GRF moment arms and joint moments acting around the talocrural and sub-talar joints werecalculated over the entire stance phase. The estimated talocrural and sub-talar joint locations show noticeable obliquity. Thekinematic and kinetic results strongly suggest that the human ankle-foot complex works as a mechanical mechanism with twodifferent configurations in stance phase of walking. These lead to a significant decrease in the GRF moment arms therebyincreasing the effective mechanical advantages of the ankle plantarflexor muscles. This reconfigurable mechanism enhancesmuscle effectiveness during locomotion by modulating the gear ratio of the ankle plantarflexor muscles in stance. This studyalso reveals many factors may contribute to the locomotor function of the human ankle-foot complex, which include not only itsre-configurable structure, but also its obliquely arranged joints, the characteristic heel-to-toe Centre of Pressure (COP) motionand also the medially acting GRF pattern. Although the human ankle-foot structure is immensely complex, it seems that itsconfiguration and each constitutive component are well tuned to maximise locomotor efficiency and also to minimise risk ofinjury. This result would advance our understanding of the locomotor function of the ankle-foot complex, and also the intrinsicdesign of the ankle-foot musculoskeletal structure. Moreover, this may also provide implications for the design of bionicprosthetic devices and the development of humanoid robots.
文摘Cutaneous nerve injury is the most common complication following foot and ankle surgery. However, clinical studies including long-term follow-up data after cutaneous nerve injury of the foot and ankle are lacking. In the current retrospective study, we analyzed the clinical data of 279 patients who underwent foot and ankle surgery. Subjects who suffered from apparent paresthesia in the cutaneous sensory nerve area after surgery were included in the study. Pa- tients received oral vitamin B^2 and methylcobalamin. We examined final follow-up data of 17 patients, including seven with sural nerve injury, five with superficial peroneal nerve injury, and five with plantar medial cutaneous nerve injury. We assessed nerve sensory function using the Medical Research Council Scale. Follow-up immediately, at 6 weeks, 3, 6 and 9 months, and 1 year after surgery demonstrated that sensory function was gradually restored in most patients within 6 months. However, recovery was slow at 9 months. There was no significant difference in sensory function between 9 months and 1 year after surgery. Painful neuromas occurred in four patients at 9 months to 1 year. The results demonstrated that the recovery of sensory func- tion in patients with various cutaneous nerve injuries after foot and ankle surgery required at least 6 months.

文摘Background: Osteomyelitis(OM) is an atypical consequence of ankle-foot trauma which is associated with long-term mental and physical morbidity and persistent pain. This study aimed to assess the health status of OM patients with war-related ankle-foot injuries.Methods: A total of 1129 veterans with ankle-foot injuries participated in a case-control study(2014–2016). Thirty patients with chronic OM of the ankle-foot were compared with 90 non-OM participants as the control group. Quality of life(QOL), life satisfaction and the ability to perform basic and instrumental activities of daily living were measured using the following questionnaires: short-form health survey(SF-36), satisfaction with life scale(SWLS), activity of daily living(ADL) and instrumental activity of daily living(IADL), respectively. OM patients were categorized according to their risk factors as A, B and C hosts using a modified version of the Cierny and Mader classification system. The one sample t-test, 2-independent sample t-test, ANOVA, Pearson correlation coefficient and multiple linear regression analyses were applied to analyze the data.Results: Ankle-foot pain leading to surgery(P <0.001) and orthosis usage(P =0.039) were more common in OM patients. There was no significant difference between the two groups in the prevalence of pulmonary and cardiovascular diseases or kidney failure and other related diseases. OM patients showed a significantly lower level of mental health compared to non-OM respondents(P=0.025). Approximately, 70.0% of ankle-foot injured veterans were dissatisfied with their life, and there was no difference between the two groups(P>0.05). Mobility was significantly lower in the OM patients than in the control group(P=0.023). Life satisfaction(P=0.001) and the ability to perform daily activities were the determinants for poor physical(P=0.018) and mental health-related quality of life(P=0.012). According to the Cierny and Mader classification system, they were all included in the type C host classification, with one major and/or three or more minor risk factors.Conclusion: A low level of quality and satisfaction of life and ability to perform activities of daily living were observed in OM patients with war-related ankle-foot injuries. Surgeries of the ankle and foot due to pain were much more common in OM patients than in non-OM participants. Since all the participants were classified as the C-host, health policy planning seems to be necessary.
文摘This review summarises the key points in taking a history and performing a comprehensive clinical examination for patients with foot and/or ankle problems. It is a useful guide for residents who are preparing for their specialty exams, as well as family doctors and any other doctor who has to deal with foot and ankle problems in adults.
文摘Football is the most popular sport worldwide and is associated with a high injury rate, most of which are the result of trauma from player contact. Ankle injuries are among the most commonly diagnosed injuries in the game. The result is reduced physical activity and endurance levels, lost game time, and considerable medical cost. Sports medicine professionals must employ the correct diagnostic tools and effective treatments and rehabilitation protocols to minimize the impact of these injuries on the player. This review examines the diagnosis, treatment, and postoperative rehabilitation for common football injuries of the ankle based on the clinical evidence provided in the current literature.
文摘Obesity is a growing problem defined as a body mass index of greater than 30 kg/m2.It is predicted that by 2030,48.9%of adults will be classified as obese which expands surgical risk factors to a broad population while increasing healthcare costs at the same time in different socioeconomic groups.This specific population has been widely studied in multiple surgical fields and published studies have shown the implications in each of these fields.The impact of obesity on orthopedic surgical outcomes has been previously reported in several total hip and knee arthroscopy studies,with evidence indicating that obesity is strongly associated with an increased risk of post operative complications together with higher revision rates.In line with increasing interest on the impact of obesity in orthopedics,there has been a similar output of publications in the foot and ankle literature.This review article evaluates several foot and ankle pathologies,their risk factors associated with obesity and subsequent management.It provides an updated,comprehensive analysis of the effects of obesity on foot and ankle surgical outcomes,with the ultimate aim of educating both surgeons and allied health professionals about the risks,benefits,and modifiable factors of operating on obese patients.
文摘Background and Objectives: Ankle injuries are the most common type of injury in healthy active individuals. If not treated properly, recurrent sprains can lead to a condition of chronic ankle instability (CAI). The present paper examines some subjects with a previous history of acute inversion ankle sprain who have developed a subsequent condition of instability, grouping them according to inclusion criteria and analyzing them through four field tests considered objective by the scientific literature: SEBT test, BEES test, TIBT test, SHT test. The data obtained were stored in order to compare them following a re-education protocol aimed at improving proprioception, balance, walking and strengthening the extrinsic and intrinsic muscles of the foot. per year. The subjects were then divided into two categories: subjects with CAI > 1 year and subjects with CAI ≤ 1 year. A protocol lasting 6 weeks was administered to both groups, trying to work on improving balance in single stance, improving static and dynamic stability, strengthening the gluteus medius and maximus (pelvis stabilizers) and strengthening of the intrinsic muscles of the foot. At the end of the protocol the subjects were all re-evaluated with the same field tests used previously and the data obtained were compared both with the pre-protocol data and with the data measured by the control subjects.
文摘BACKGROUND Arthrodesis is the surgical fusion of a diseased joint for the purposes of obtaining pain relief and stability.There have been numerous fixation devices described in literature for foot and ankle arthrodesis,each with their own benefits and drawbacks.AIM To review the use of intraosseous devices in foot and ankle surgery.METHODS There were 9 papers included in the review(6 clinical and 3 experimental studies)all evaluating arthrodesis in the foot and ankle using the IOFIX device(Extremity Medical™,Parsippany,NJ,United States).Outcome scores,union rates,as well as complications were analysed.RESULTS IOFIX appears to be safe and effective in achieving arthrodesis of the 1st metatarsophalangeal,and talonavicular joints with early rehabilitation.In comparison to plate/screw constructs there were fewer soft tissue complications and issues of metalwork prominence.Cadaveric and biomechanical studies on the use of intramedullary fixation for fusion of the tarsometatarsal and ankle joint showed decreased load to failure,cycles to failure and stiffness in comparison to traditional fusion methods using plates and screws,however IOFIX devices produced higher compressive forces at the joint.CONCLUSION We describe the reasons for which this biomechanical behavior of the intraosseous fixation may be favorable,until prospective and comparative studies with largersample size and longer follow-up confirm the effectiveness and limitations of the method.

文摘Modern conflicts demand substantial physical and psychological exertion,often resulting in fatigue and diminished combat or operational readiness.Several exoskeletons have been developed recently to address these challenges,presenting various limitations that affect their operational or everyday usability.This article evaluates the performance of a dual-purpose passive ankle exoskeleton developed for the reduction of metabolic costs during walking,seeking to identify a force element that could be applied to the target population.Based on the 6-min walk test,twenty-nine subjects participated in the study using three different force elements.The results indicate that it is possible to reduce metabolic expenditure while using the developed exoskeleton.Additionally,the comfort and range of motion results verify the exoskeleton's suitability for use in uneven terrain and during extended periods.Nevertheless,the choice of the force element should be tailored to each user,and the control system should be adjustable to optimise the exoskeleton's performance.
文摘BACKGROUND The recovery of limb function after ankle fracture surgery is a gradual process.The main purpose of implementing early functional exercise,joint mobility,muscle contraction function,passive ankle flexion and extension exercises,or physical factor therapy techniques is to achieve the rapid recovery of normal physiological limb function.However,currently the most effective rehabilitation training method is staged limb functional exercise,which promotes rapid recovery of limb function while preventing adverse consequences caused by overwork or insufficient training.Staged limb functional exercise divides the rehabilitation process into multiple stages,each of which has specific training objectives and contents.This method helps patients gradually restore limb function.Nevertheless,some patients still exhibit poor limb function after standardized exercise.Therefore,a functional evaluation should be performed to analyze the impact of staged functional training after ankle fracture surgery.AIM To perform a functional evaluation and determine the influencing factors of staged functional training in patients with ankle fracture.METHODS A retrospective study enrolled 150 patients who underwent surgical treatment for ankle fracture from May 2020 to May 2022 at our hospital.Univariate and multivariate linear regression analyses were performed on general data,functional exercise compliance scale for orthopedic patients,Social Support Rating Scale(SSRS),American Orthopedic Foot and Ankle Score(AOFAS)Ankle-Hindfoot Score,and pain factors[serum bradykinin(BK),prostaglandin E2(PGE2),5-hydroxytryptamine(5-HT)].RESULTS Based on the AOFAS Ankle-Hindfoot Scale,the cases were divided into the excellent function(n=111)and ordinary function(n=39)groups.Univariate analysis revealed that monthly family income,education level,diabetes mellitus,functional exercise compliance scale of orthopedic patients score,SSRS,BK,PGE2,and 5-HT significantly influenced limb function after ankle fracture(P<0.05);Multiple linear regression analysis showed that the functional exercise compliance scale score,SSRS,BK,PGE2,and 5-HT were independent risk factors affecting functional performance after staged functional exercise(P<0.05).CONCLUSION Exercise compliance,SSRS,and pain level are the independent risk factors affecting functional performance after staged functional training following ankle surgery.Clinical nursing care after ankle surgery should include analgesic and health education measures to ensure optimal recovery of limb function.

文摘The kinematic equivalent model of an existing ankle-rehabilitation robot is inconsistent with the anatomical structure of the human ankle,which influences the rehabilitation effect.Therefore,this study equates the human ankle to the UR model and proposes a novel three degrees of freedom(3-DOF)generalized spherical parallel mechanism for ankle rehabilitation.The parallel mechanism has two spherical centers corresponding to the rotation centers of tibiotalar and subtalar joints.Using screw theory,the mobility of the parallel mechanism,which meets the requirements of the human ankle,is analyzed.The inverse kinematics are presented,and singularities are identified based on the Jacobian matrix.The workspaces of the parallel mechanism are obtained through the search method and compared with the motion range of the human ankle,which shows that the parallel mechanism can meet the motion demand of ankle rehabilitation.Additionally,based on the motion-force transmissibility,the performance atlases are plotted in the parameter optimal design space,and the optimum parameter is obtained according to the demands of practical applications.The results show that the parallel mechanism can meet the motion requirements of ankle rehabilitation and has excellent kinematic performance in its rehabilitation range,which provides a theoretical basis for the prototype design and experimental verification.

文摘The current parallel ankle rehabilitation robot(ARR)suffers from the problem of difficult real-time alignment of the human-robot joint center of rotation,which may lead to secondary injuries to the patient.This study investigates type synthesis of a parallel self-alignment ankle rehabilitation robot(PSAARR)based on the kinematic characteristics of ankle joint rotation center drift from the perspective of introducing"suitable passive degrees of freedom(DOF)"with a suitable number and form.First,the self-alignment principle of parallel ARR was proposed by deriving conditions for transforming a human-robot closed chain(HRCC)formed by an ARR and human body into a kinematic suitable constrained system and introducing conditions of"decoupled"and"less limb".Second,the relationship between the self-alignment principle and actuation wrenches(twists)of PSAARR was analyzed with the velocity Jacobian matrix as a"bridge".Subsequently,the type synthesis conditions of PSAARR were proposed.Third,a PSAARR synthesis method was proposed based on the screw theory and type of PSAARR synthesis conducted.Finally,an HRCC kinematic model was established to verify the self-alignment capability of the PSAARR.In this study,93 types of PSAARR limb structures were synthesized and the self-alignment capability of a human-robot joint axis was verified through kinematic analysis,which provides a theoretical basis for the design of such an ARR.

文摘Background:The ankle-foot injuries are among the war-related injuries that cause many serious secondary problems for a lifetime.This nationwide study aimed to assess health-related quality of life and the ability to perform activities of daily living in veterans with ankle-foot injuries due to the Iran-Iraq war.Methods:A total of 1079 veterans with ankle-foot injuries were enrolled in a cross-sectional study from 2014 to 2016.Demographic characteristics,including age,gender,marital status,disability percent,educational level,employment and additional injuries,were collected.The ability to perform daily activities was assessed using the Barthel activities of daily living(ADL)and Lawton instrumental activities of daily living(IADL)Indexes.Physical and mental health-related quality of life(HRQOL)data were measured via the SF-36 subscales.The data were compared with those of bilateral lower limb amputees(BLLAs)and of the general Iranian population.Statistical analyses,including Pearson’s correlation coefficient,one-sample t-test and analysis of variance(ANOVA),were performed using SPSS16.0.A multiple linear regression model was used to determine the contribution of independent variables to the Physical Component Summary(PCS)and Mental Component Summary(MCS).Results:The highest and lowest scores were observed for mental health(48.93±20.69)and bodily pain(28.16±21.74),respectively.The mean scores of veterans with ankle-foot injuries on the SF-36 were significantly lower on all eight measures than those of the general Iranian male population and of the bilateral lower limb amputees(P<0.001).The mean scores of ADLs and IADLs were 83.9±16.3 and 5.3±2.0,respectively.The higher dependency in ADLs(P<0.001)and IADLs(P<0.001),the higher disability rate(P<0.001)and additional injury(P<0.001)were significant determinants of the PCS.ADL(P<0.001)and IADL(P<0.001)limitations,additional injury(P<0.001),history of hospitalization in the year preceding the study(P=0.007)and employment(P=0.001)were reported as determinants of the MCS.Conclusion:The results strongly suggest that veterans with ankle-foot injuries suffer from critically poor healthrelated quality of life.The main predicting factors of HRQOL were the disability to perform ADLs/IADLs,suffering two or more injuries,a history of hospitalization in the year preceding the study and unemployment.
文摘Post-traumatic osteoarthritis(PTOA)is a complex and painful problem in the foot and ankle.Ninety percent of osteoarthritis cases in the foot and ankle can be classified as post-traumatic.PTOA can affect any of the 33 joints in the foot and the ankle.Distraction arthroplasty is a method for treatment of early arthritic joints without fusing or replacing them and its effectiveness has been well documented.The purpose of this case series is to present our successful experiences and positive results using distraction arthroplasty to treat PTOA in the ankle,subtalar,first metatarsophalangeal,and second tarsometatarsal joints,and to present distraction arthroplasty as a viable alternative to invasive joint sacrificing procedures such as arthrodesis or arthroplasty.Distraction Arthroplasty effectively and safely treats PTOA and improves the stability of joints in the Foot and Ankle.Additionally,the use of bone marrow aspirate concentrate as an adjuvant can improve the long-term functional and structural outcomes of the joint,and can prolong the need for further,more aggressive surgical interventions such as fusion or arthroplasty.

文摘Background: War-related traumas can lead to orthopedic and neurological disorders in victims. However, the scope of such disorders may expand months or even years after the trauma. Orthotic treatment as a rehabilitation process aims to enable people with disabilities to reach and maintain their optimal physical, sensory, intellectual, psychological, and social functional levels. This study aimed to investigate the rate of using orthoses among Iranian veterans with neuromuscular and skeletal disorders of the ankle and foot. Furthermore, the priorities of orthotic treatment in those veterans were explored.Methods: This qualitative study was a national health needs assessment conducted in 11 provinces of Iran during 2011–2016. A stakeholder research group was established to survey the veterans in respect to their demographic variables, activities of daily living, current health conditions, and rate of using orthoses.Results: Overall, 907 of the 1124 veteran participants completed the survey(response rate: 80.7%). Most of the veterans were men(97.7%), and their age and disability rate were 52.07±8.13 years and 31.92%±14.93%, respectively. Nearly 42% of the veterans had experience in using orthoses on a daily and weekly basis. As physical ambulation was the main problematic activity in veterans, most of them were using medical shoes and foot orthoses. Nearly 37% of veterans were in need of some type of lower limb orthoses on the contralateral side to compensate for their hip inequality. In sequential order, the most in need orthoses for veterans were foot orthoses(n=538), medical shoes(n=447), lower limb orthoses on the contralateral side(n=320), spinal orthoses(n=273), and upper limb orthoses(n=86).Conclusion: In spite of the high demands for orthoses among Iranian veterans with ankle and foot disorders, the use of orthoses is insufficient. Hence, there is a discrepancy between the current rate of orthoses use and its ideal situation, and more resources should be provided for service providers to be able to serve veterans. Moreover, veterans should be educated regarding orthoses, their use, and their impacts on the user's health status. The findings of a needs assessment of orthoses can be used in strategic planning and decision making to improve health care services for Iranian veterans.
