The application of maxillofacial prosthesis is an alternative to surgery in functional–aesthetic facial reconstruction. Computer aided design and computer aided manufacturing has opened up a new approach to the fabrication of maxillofacial prosthesis. An intelligentized rapid simulative design and manufacture system for prosthesis was developed to facilitate the prosthesis fabrication procedure.Methods: Maxillofacial prosthesis rapid simulation design and rapid fabrication system consists of three components: digital impression, intelligentized prosthesis designing, and rapid manufacturing. The patients' maxillofacial digital impressions were taken with Structured-light 3D scanner; and then the 3D model of prostheses and their negative molds could be designed in specific software; finally, with the resin molds fabricated by rapid prototyping machine, the prostheses could be produced directly and quickly.Results: Fifteen patients of maxillofacial defect caused by traumatic injuries received prosthesis rehabilitation provided by the established system. The contour of the prostheses coordinated properly with the appearance of the patients, and the uniform-thickness border sealed well to adjacent tissues. All the patients were satisfied with their prostheses.Conclusions: The rapid simulative rehabilitation system of maxillofacial defects has been approaching completion. It could provide advanced technological reservation for the Army in the issue of maxillofacial defect rehabilitation.展开更多

We describe a patient with SLE complicated by PML and ameliorated by comprehensive rehabilitation. We also review the epidemiology, pathology, imaging characteristics, and treatment of PML. Patient Concerns: We found a patient with SLE with PML improved by multidisciplinary rehabilitation techniques. Diagnoses, Interventions, and Outcomes: We diagnosed a PML with a 13-year history of SLE and lupus nephritis after longtime immunosuppressive therapy. The patient underwent a comprehensive, multifaceted rehabilitation program, including drug therapy, integrated physical therapy, occupational therapy, acupuncture, music therapy, computer-aided cognitive rehabilitation training, and behavioral management training. This rehabilitation program improved her motor function and activities of daily living. Conclusions: Her condition improved in the short term through comprehensive rehabilitation, including physical, speech, and cognitive therapy. Therefore, we recommend comprehensive rehabilitation to improve the function and activities of daily living in patients with PML.展开更多

In the context of rehabilitation of a hemiplegic ankle, a longitudinal therapy regimen incorporating stretching and then a series of repetitions for raising and lowering the foot of the hemiplegic ankle can be applied over the course of a year. Using a smartphone equipped with an application to function as a wearable and wireless gyroscope platform mounted to the dorsum of the foot by an armband, the initial phase and final phase of a one year longitudinally applied therapy regimen can be objectively quantified and recorded for subsequent machine learning. Considerable classification accuracy is attained to distinguish between the initial phase and final phase by a support vector machine for a one year longitudinally applied hemiplegic ankle therapy regimen based on the gyroscope signal data obtained by a smartphone functioning as a wearable and wireless inertial sensor system. .展开更多

文摘BACKGROUND Stroke often results in significant respiratory dysfunction in patients.Respiratory muscle training(RMT)has been proposed as a rehabilitative intervention to address these challenges,but its effectiveness compared to routine training remains debated.This systematic review and meta-analysis aim to evaluate the effects of RMT on exercise tolerance,muscle strength,and pulmonary function in post-stroke patients.AIM To systematically assess the efficacy of RMT in improving exercise tolerance,respiratory muscle strength,and pulmonary function in patients recovering from a stroke,and to evaluate whether RMT offers a significant advantage over routine training modalities in enhancing these critical health outcomes in the post-stroke population.METHODS Following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines,a comprehensive search across PubMed,Embase,Web of Science,and the Cochrane Library was conducted on October 19,2023,without temporal restrictions.Studies were selected based on the predefined inclusion and exclusion criteria focusing on various forms of RMT,control groups,and outcome measures[including forced expiratory volume in the first second(FEV1),forced vital capacity(FVC),maximal voluntary ventilation(MVV),peak expiratory flow(PEF),maximal inspiratory pressure(MIP),maximal expiratory pressure(MEP),and 6-min walking test(6MWT)].Only randomized controlled trials(RCTs)were included.Data extraction and quality assessment were conducted independently by two reviewers using the Cochrane Collaboration's risk of bias tool.Statistical analyses,including those using the fixed-effect and random-effects models,sensitivity analysis,and publication bias assessment,were performed using Review Manager software.RESULTS A total of 15 RCTs were included.Results indicated significant improvements in MIP(12.51 cmH2O increase),MEP(6.24 cmH2O increase),and various pulmonary function parameters(including FEV1,FVC,MVV,and PEF).A substantial increase in 6MWT distance(22.26 meters)was also noted.However,the heterogeneity among studies was variable,and no significant publication bias was detected.CONCLUSION RMT significantly enhances walking ability,respiratory muscle strength(MIP and MEP),and key pulmonary function parameters(FEV1,FVC,MVV,and PEF)in post-stroke patients.These findings support the incorporation of RMT into post-stroke rehabilitative protocols.
文摘BACKGROUND Coronary stent implantation is usually used to treat unstable angina to alleviate stenosis or occlusion,promoting blood flow restoration and alleviating symptoms such as myocardial ischemia.And postoperative cardiac rehabilitation is essential for enhancing recovery and prognosis.Nevertheless,conventional rehabilitation lacks specificity,particularly for elderly patients with multiple comorbidities and poor compliance,rendering it less effective.AIM To investigate the effects of systematic cardiac rehabilitation training in elderly patients with unstable angina following coronary stenting intervention.METHODS A retrospective enrollment was conducted comprising fifty-four elderly patients with unstable angina pectoris who underwent systematic cardiac rehabilitation training after receiving coronary intervention as the rehabilitation group,while fifty-three elderly patients who received basic nursing and rehabilitation guidance measures after coronary intervention were assigned to the control group.Differences in Seattle Angina Questionnaire scores,survival quality(SF-36)scores,cardiopulmonary exercise function assessment index,echocardiographic cardiac function index,and adverse cardiovascular events were compared between the two groups.RESULTS After intervention,the rehabilitation group observed greater VO2 Max,maximum metabolic equivalent,eft ventricular ejection fraction,left ventricular end-diastolic diameter and smaller left ventricular end-systolic diameter.And the rehabilitation group observed greater scores of physical activity limitation,stable angina pectoris,treatment satisfaction,and SF-36 score.The incidence of adverse cardiovascular events in the two groups,showed no significant difference.CONCLUSION Systematic cardiac rehabilitation following coronary stenting in elderly patients with unstable angina pectoris can enhance cardiac function recovery,consequently enhancing both quality of life and cardiopulmonary exercise tolerance.

文摘Objective:Previous research has demonstrated that pulmonary Daoyin could be an efficacious way to ameliorate the physical and psychological state of sufferers with chronic obstructive pulmonary disease(COPD)and bolster the quality of life.However,the results are not consistent.Thus,the objective of this research is to assess the impacts of pulmonary Daoyin in individuals with COPD.Methods:Relevant articles were searched in Web of Science,Cochrane Library,PubMed,EMBASE,SinoMed,CNKI,Wanfang,and VIP from database inception to January 2024.Results:There were a total of 15 randomized controlled trials(RCTs)included in this meta-analysis involving 1732 patients,of which 864 participated in the intervention group and 868 in the control group.When comparing with the control group,the COPD patients practicing pulmonary Daoyin demonstrated a significant improvement in 6 min walking distance(mean difference[MD]=24.53,95%confidence interval[CI][18.55,30.52],P<0.00001),forced expiratory volume in the 1 s(FEV_(1))(MD=0.39,95%CI[0.18,0.59],P=0.0002),percentage of FEV_(1)to the predicted value(FEV_(1)%)(MD=5.35,95%CI[3.22,7.48],P<0.0001),the forced vital capacity(FVC)(MD=0.39,95%CI[0.06,0.73],P=0.02),percentage of FVC to the predicted value(FVC%)(MD=7.52,95%CI[4.91,10.13],P<0.00001),the ratio of FEV_(1)/FVC(MD=4.95,95%CI[0.91,8.99],P=0.02),peak expiratory flow rate(standardized MD=0.98,95%CI[0.74,1.22],P<0.00001),modified Medical Research Council(mMRC)scale(MD=-0.47,95%CI[-0.89,-0.04],P=0.03),and Borg scale(MD=-0.65,95%CI[-0.75,-0.55],P<0.00001).Conclusions:Our findings may illuminate the influence of pulmonary Daoyin on exercise ability,breathlessness,and pulmonary function in COPD patients.More rigorous RCTs with larger samples and longer-term interventions will be required moving forward.
文摘Physical inactivity remains in high levels after cardiac surgery,reaching up to 50%.Patients present a significant loss of functional capacity,with prominent muscle weakness after cardiac surgery due to anesthesia,surgical incision,duration of cardiopulmonary bypass,and mechanical ventilation that affects their quality of life.These complications,along with pulmonary complications after surgery,lead to extended intensive care unit(ICU)and hospital length of stay and significant mortality rates.Despite the well-known beneficial effects of cardiac rehabilitation,this treatment strategy still remains broadly underutilized in patients after cardiac surgery.Prehabilitation and ICU early mobilization have been both showed to be valid methods to improve exercise tolerance and muscle strength.Early mobilization should be adjusted to each patient’s functional capacity with progressive exercise training,from passive mobilization to more active range of motion and resistance exercises.Cardiopulmonary exercise testing remains the gold standard for exercise capacity assessment and optimal prescription of aerobic exercise intensity.During the last decade,recent advances in healthcare technology have changed cardiac rehabilitation perspectives,leading to the future of cardiac rehabilitation.By incorporating artificial intelligence,simulation,telemedicine and virtual cardiac rehabilitation,cardiac surgery patients may improve adherence and compliance,targeting to reduced hospital readmissions and decreased healthcare costs.
文摘BACKGROUND Stroke is a common disabling disease,whether it is ischemic stroke or hemorrhagic stroke,both can result in neuronal damage,leading to various manifestations of neurological dysfunction.AIM To explore of the application value of swallowing treatment device combined with swallowing rehabilitation training in the treatment of swallowing disorders after stroke.METHODS This study selected 86 patients with swallowing disorders after stroke admitted to our rehabilitation department from February 2022 to December 2023 as research subjects.They were divided into a control group(n=43)and an observation group(n=43)according to the treatment.The control group received swallowing rehabilitation training,while the observation group received swallowing treatment device in addition to the training.Both groups underwent continuous intervention for two courses of treatment.RESULTS The total effective rate in the observation group(93.02%)was higher than that in the control group(76.74%)(P=0.035).After intervention,the oral transit time,swallowing response time,pharyngeal transit time,and laryngeal closure time decreased in both groups compared to before intervention.In the observation group,the oral transit time,swallowing response time,and pharyngeal transit time were shorter than those in the control group after intervention.However,the laryngeal closure time after intervention in the observation group was compared with that in the control group(P=0.142).After intervention,average amplitude value and duration of the genioglossus muscle group during empty swallowing and swallowing 5 mL of water are reduced compared to before intervention in both groups.After intervention,the scores of the chin-tuck swallowing exercise and the Standardized Swallowing Assessment are both reduced compared to pre-intervention levels in both groups.However,the observation group scores lower than the control group after intervention.Additionally,the Functional Oral Intake Scale scores of both groups are increased after intervention compared to pre-intervention levels,with the observation group scoring higher than the control group after intervention(P<0.001).The cumulative incidence of complications in the observation group is 9.30%,which is lower than the 27.91%in the control group(P=0.027).CONCLUSION The combination of swallowing therapy equipment with swallowing rehabilitation training can improve the muscle movement level of the genioglossus muscle group,enhance swallowing function,and prevent the occurrence of swallowing-related complications after stroke.
文摘BACKGROUND Cerebral infarction,previously referred to as cerebral infarction or ischemic stroke,refers to the localized brain tissue experiencing ischemic necrosis or softening due to disorders in brain blood supply,ischemia,and hypoxia.The precision rehabilitation nursing model for chronic disease management is a continuous,fixed,orderly,and efficient nursing model aimed at standardizing the clinical nursing process,reducing the wastage of medical resources,and improving the quality of medical services.AIM To analyze the value of a precise rehabilitation nursing model for chronic disease management in patients with cerebral infarction.METHODS Patients(n=124)admitted to our hospital with cerebral infarction between November 2019 and November 2021 were enrolled as the study subjects.The random number table method was used to divide them into a conventional nursing intervention group(n=61)and a model nursing intervention group(n=63).Changes in the nursing index for the two groups were compared after conventional nursing intervention and precise rehabilitation intervention nursing for chronic disease management.RESULTS Compared with the conventional intervention group,the model intervention group had a shorter time to clinical symptom relief(P<0.05),lower Hamilton Anxiety Scale and Hamilton Depression Scale scores,a lower incidence of total complications(P<0.05),a higher disease knowledge mastery rate,higher safety and quality,and a higher overall nursing satisfaction rate(P<0.05).CONCLUSION The precision rehabilitation nursing model for chronic disease management improves the clinical symptoms of patients with cerebral infarction,reducing the incidence of total complications and improving the clinical outcome of patients,and is worthy of application in clinical practice.

文摘Introduction: Little is known about the feasibility and effectiveness of rehabilitative treatment for systemic lupus erythematosus (SLE) in individuals with progressive multifocal leukoencephalopathy (PML). We describe a patient with SLE complicated by PML and ameliorated by comprehensive rehabilitation. We also review the epidemiology, pathology, imaging characteristics, and treatment of PML. Patient Concerns: We found a patient with SLE with PML improved by multidisciplinary rehabilitation techniques. Diagnoses, Interventions, and Outcomes: We diagnosed a PML with a 13-year history of SLE and lupus nephritis after longtime immunosuppressive therapy. The patient underwent a comprehensive, multifaceted rehabilitation program, including drug therapy, integrated physical therapy, occupational therapy, acupuncture, music therapy, computer-aided cognitive rehabilitation training, and behavioral management training. This rehabilitation program improved her motor function and activities of daily living. Conclusions: Her condition improved in the short term through comprehensive rehabilitation, including physical, speech, and cognitive therapy. Therefore, we recommend comprehensive rehabilitation to improve the function and activities of daily living in patients with PML.
文摘With the amalgamation of wearable systems equipped with inertial sensors, such as a gyroscope, and machine learning a therapy regimen can be objectively quantified, and then the initial phase and final phase of a one year therapy regimen can be distinguished through machine learning. In the context of rehabilitation of a hemiplegic ankle, a longitudinal therapy regimen incorporating stretching and then a series of repetitions for raising and lowering the foot of the hemiplegic ankle can be applied over the course of a year. Using a smartphone equipped with an application to function as a wearable and wireless gyroscope platform mounted to the dorsum of the foot by an armband, the initial phase and final phase of a one year longitudinally applied therapy regimen can be objectively quantified and recorded for subsequent machine learning. Considerable classification accuracy is attained to distinguish between the initial phase and final phase by a support vector machine for a one year longitudinally applied hemiplegic ankle therapy regimen based on the gyroscope signal data obtained by a smartphone functioning as a wearable and wireless inertial sensor system. .

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A wide open bottom story of a frame building is often expected by owners for use as a garage or shops.However,this leads to weak stories due to abrupt changes in lateral stiffness and often results in unexpected story collapse as observed in many previous earthquakes.To retrofit frame buildings that have experienced weak story damage,a tendon system is proposed in this study,which consists of a set of swaying columns and tendons.The swaying columns are used to uniformly redistribute the lateral deformation along the height,while the tendons provide extra lateral stiffness and renders the entire structural system a re-centering capability.To avoid unnecessary forces to swaying columns,pin-connections are used at the bottom.Tendons are placed over the entire story to gain large elastic displacements.Parametric analysis reveals that the swaying column,with a stiffness of about 0.9 times that of the weak story,and the tendons attached at the roof,with a stiffness of 0.04 times that of the weak story,can provide the optimal performance with a maximum residual story drift angle of less than 0.5%.Online hybrid tests were carried out,which demonstrated that uniformly distributed story drifts and acceptable residual deformation could be achieved by the proposed tendon system.

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In this editorial,we comment on the article by Stafie et al.Inflammatory bowel disease(IBD)constitutes a cluster of chronic and progressive inflammatory disorders affecting the digestive system.IBD can impede an individual’s capacity to perform daily activities,hinder work productivity,limit physical capabilities,and negatively impact medical outcomes.Although physical activity and structured exercise programs are becoming increasingly important in many chronic inflammatory diseases,they are not being sufficiently implemented in IBD patients.Effective prevention of future disability and drug dependence in IBD patients requires timely diagnosis and treatment of musculoskeletal problems,including sarcopenia,as well as decreased muscle strength,aerobic capacity,and bone mineral density.To improve treatment outcomes for IBD patients,it is crucial to develop individualized rehabilitation programs tailored to their unique needs.Equally critical is the active participation of pertinent departments in this process.It is imperative to highlight the significance of creating a personalized rehabilitation program with a multidisciplinary approach in IBD management.

文摘This paper proposes an explicit scheme to analyze the failure of a subsea polyhedral tunnel-liner system with an inverted arch under mechanical loading and fire fields.The thin-walled liner is made of Functionally Graded Materials(FGMs),which may improve the stability behavior of the tunnel-liner system.Hydrostatic pressure is inevitable in the liner since underground water may penetrate the cracks of the tunnel,and reach the outer surface of the liner.In addition,an elevated temperature loading is taken into account,considering that fire may occur in the tunnel-liner system.Under the combination of mechanical loading and thermal loading,the liner deforms into a single-lobe shape,which is depicted by a trigonometric function.The total potential energy is expressed quantitatively after the energy approach and thin-walled shell theory are used.The minimum potential energy is obtained when the critical buckling occurs.The critical buckling pressure is calculated,which considers the effect of the thermal field.The present analytical prediction is subsequently compared precisely with other closed-form solutions.Finally,the effects of several parameters,such as the geometric shapes,temperature variations,and volume fraction indices,are discussed to further survey the buckling performance of the nonlinear buckling of an FGM polyhedral liner with an inverted arch.One may address a polyhedral liner with fewer polyhedral sides,and a lower volume fraction index is recommended to rehabilitate cracked tunnels in engineering applications.
