Background: The shape of the capitellum has been traditionally described in anatomy books as part of a sphere. Alteration in the capitellar morphology following pathologies such as fractures, osteochondrosis, and degenerative arthritis has been associated with less optimum functional results. Aim: To define the relationship between the sphericity of the capitellar morphology as measured on trauma series plain radiographs and the elbow range of motion. Methods: 40 patients were included in the study. All patients recruited from the upper limb clinics presented with non-elbow joint-related complaints. The elbow range of motion was measured using a standardized technique. Digital anteroposterior and lateral radiographs of patients’ elbows were used to measure capitellar circularity using the ImageJ processing program and circularity calculation equation. Correlation analyses were conducted between the degree of capitellar sphericity and elbow range of motion. Results: The results of measurements from the anteroposterior radiographs showed a positive correlation between increased circularity and an increase in the range of flexion, pronation, and supination. The range of extension decreased with the increased circularity of the capitellum. This trend was repeated with measures of lateral radiographs but was statistically not significant. Conclusion: Native capitellar circularity has an impact on the elbow range of motion. This should be put into consideration when dealing with pathologies that affect capitellar morphology. 展开更多

Background:Arthrofibrosis is a joint disorder characterized by excessive scar formation in the joint tissues.Vitamin E is an antioxidant with potential anti-fibroblastic effect.The aim of this study was to establish an arthrofibrosis rat model after joint replacement and assess the effects of vitamin E supplementation on joint fibrosis.Methods:We simulated knee replacement in 16 male Sprague–Dawley rats.We immobilized the surgical leg with a suture in full flexion.The control groups were killed at 2 and 12 weeks(n=5 per group),and the test group was supplemented daily with vitamin E(0.2 mg/mL)in their drinking water for 12 weeks(n=6).We performed histological staining to investigate the presence and severity of arthrofibrosis.Immunofluorescent staining andα2-macroglobulin(α2M)enzyme-linked immunosorbent assay(ELISA)were used to assess local and systemic inflammation.Static weight bearing(total internal reflection)and range of motion(ROM)were collected for functional assessment.Results:The ROM and weight-bearing symmetry decreased after the procedure and recovered slowly with still significant deficit at the end of the study for both groups.Histological analysis confirmed fibrosis in both lateral and posterior periarticular tissue.Vitamin E supplementation showed a moderate anti-inflammatory effect on the local and systemic levels.The vitamin E group exhibited significant improvement in ROM and weight-bearing symmetry at day 84 compared to the control group.Conclusions:This model is viable for simulating arthrofibrosis after joint replacement.Vitamin E may benefit postsurgical arthrofibrosis,and further studies are needed for dosing requirements. 展开更多

Objective:This study evaluates the reliability of smartphone compass software in measuring the cervical range of motion in healthy people.Methods:We selected 40 healthy intern college students from Tianjin Hospital from June to August 2022 to participate in this study.Two physiotherapists used a smartphone(iPhone 11256 Gb(model A2223))compass software to measure six directions of motion of the cervical spine in 40 subjects in a total of 3 rounds each.The intraclass correlation coefficient was used to compare the reliability intra-group,and the Pearson correlation coefficient was also used to compare the correlation between groups,with P<0.05 being statistically significant.Results:The intraclass correlation coefficient showed good reliability(>0.5)in cervical range of motion(CROM),especially in cervical flexion and right rotation(>0.9).In the correlation comparison between the two groups,the Spearman comparison was used,and the six directions of the cervical spine were significantly correlated(P<0.05).Conclusion:The built-in compass software in smartphones has good reliability in measuring CROM in healthy people. 展开更多

Objective: To observe the tested results of the segmental range of motion (ROM) of lumbar spine by charge couple device (CCD)-based system for 3-dimensional real-time positioning (CCD system), and to analyze its clinical significance. Methods: Seven patients with lumbar joint dysfunction and 8 healthy subjects were tested twice by the CCD-based system with an interval of 10 min. Results: The ROM of the patients was obviously lesser than that of the healthy subjects. The measuring data of segmental ROM of lumbar spine by CCD system is correlated significantly to the same data checked later on the same subjects in every direction of the movements. The differences between two checks are usually less than 1 degree. Conclusion: Specially designed CCD based system for 3-dimensional real-time positioning could objectively reflect the segmental ROM of lumbar spine. The system would be of great clinical significance in the assessment of the biomechanical dysfunction of lumbar spine and the effect of the treatment applied. 展开更多

The purpose of this study was to evaluate factors that affect initiation of early postoperative range of motion (ROM) rehabilitation and to investigate whether the postoperative ROM and clinical outcomes were affected by initiation of early ROM, immobilization and other factors. We conducted a retrospective analysis of tibial plateau fractures treated using stable internal fixation between December 2003 and June 2007. The resulting degree of flexion and Rasmussen Clinical and Radiographic Scores were evaluated. Thirty-nine patients were included, and 23 patients underwent a lateral submeniscal arthrotomy for evaluation of joint surface reduction, with 6 lateral meniscus lesions identified via arthrotomy. Three lateral collateral ligament lesions, 3 medial collateral ligament lesions and 1 anterior cruciate ligament lesion were found. Meniscus and ligament lesions significantly and negatively affected the initiation of knee joint ROM. Early ROM was achieved in 26 cases and 13 patients underwent immobilization for 4 weeks. At the final evaluation, the early ROM group had 130.42° ± 5.50° of flexion, compared with 122.92° ± 5.28° in the immobilization group. Moreover, the final Rasmussen score was 25.69 ± 2.92 in the early motion group, compared with 22.61 ± 3.5 in the immobilization group. There was no difference between radiographic scores of the groups. Although the initiation of early ROM improved the clinical results, soft tissue lesions influenced initiation of early knee joint motion. Therefore, meniscus and ligament injuries should be considered as prognostic factors in similar cases. 展开更多

Repetitive transcranial magnetic stimulation (rTMS) has recently been demonstrated to improve motor function after stroke. However, no study has yet tested the synergetic effects of physical exercise on rTMS in clinical settings. We investigated the effect of a 6-session course of low frequency rTMS on contralesional primary motor cortex combined with range-of motion (ROM) exercise on paretic hand function in female stroke patients. This was a single-blind study of the effects of rTMS with or without ROM exercise in female hemiplegic patients after stroke. All patients underwent rTMS on the contralesional primary motor cortex for 15 minutes and ROM exercise on the paretic hand. The cortical excitability determined by the amplitude and latency of the motor evoked potential (MEP) was measured in both first dorsal interosseous (FDI) muscles. We also evaluated arm function using Box and Block, arm reach, 9-hole pegboard, power grip, and pinch grip force tests. The rTMS-induced MEP amplitude of the paretic side significantly increased whereas the non-paretic side showed a decrease through every session. However, the MEP latency significantly increased on the non-paretic hand at post-rTMS with exercise, but a tendency of decrement on paretic hand at same application. Motor function showed improvement in the 9-hole pegboard and arm reach tests at post-rTMS with exercise on the paretic side compared with the non-paretic side. A significant correlation was especially noted between motor function and MEP on the paretic side of stroke patients. Low frequency rTMS with ROM exercise improved hand function after stroke. This may, in part, result in additional rehabilitation in stroke patients. 展开更多

BACKGROUND There is a lack of studies on the effects of enhanced recovery after surgery(ERAS)with multidisciplinary collaboration on the nursing outcomes of total knee arthroplasty(TKA).AIM To explore the effect of ERAS with multidisciplinary collaboration on nursing outcomes after TKA.METHODS We retrospectively analyzed the clinical data of 80 patients who underwent TKA at a tertiary hospital between January 2021 and December 2022.The patients were divided into two groups according to the nursing mode:the ERAS group(n=40)received ERAS with multidisciplinary collaboration,and the conventional group(n=40)received routine nursing.The following indicators were compared between the two groups:length of hospital stay,hospitalization cost,intraoperative blood loss,hemoglobin level 24 h after surgery,visual analog scale(VAS)score for pain,range of motion(ROM)of the knee joint,Hospital for Special Surgery(HSS)knee score,and postoperative complications.RESULTS The ERAS group had a significantly shorter length of hospital stay,lower hospitalization cost,less intraoperative blood loss,higher hemoglobin level 24 h after surgery,lower VAS score for pain,higher knee joint ROM,and higher HSS knee score than the conventional group(all P<0.05).There was no significant difference in the incidence of postoperative complications between the two groups(P>0.05).CONCLUSION Multidisciplinary collaboration with ERAS can reduce blood loss,shorten hospital stay,and improve knee function in patients undergoing TKA. 展开更多

Purpose: Belt electrode skeletal muscle electrical stimulation (B-SES) can stimulate large portions of muscles including deep sites without localisation of the stimulation area. The purpose of this study is to investigate both immediate treatment effects of B-SES and long-term treatment effects of B-SES with passive exercise on range of motion (ROM) and muscle tone of lower extremities in bedridden elderly patients. Methods: Outcome measures before and after B-SES treatment alone (4 Hz, 20 min, both lower extremities) were examined for the immediate effect. Outcome measures were: ROM and Modified Ashworth scale (MAS) of hip flexion and adduction;knee flexion and extension;and knee joint distance at position of flexion abduction in hip (distance of knee). A randomized crossover trial was conducted to examine the long-term effect of adding B-SES to passive exercise on ROM and MAS. Results and Discussion: The immediate effect study had 18 patients. ROM and MAS of 4 joint angles in 2 joints and distance of knee significantly improved after B-SES treatment. The long-term effect study had 11 patients. Friedman test revealed ROM and MAS of 4 joint angles in 2 joints and distance of knee significantly improved during B-SES intervention but not control intervention. B-SES in addition to passive stretch has a more statistically significant effect on contracture and spasticity in large portions of the lower extremities of bedridden elderly patients than passive stretching alone. Conclusions: We consider B-SES a useful tool to improve the ROM in lower extremities of bedridden patients. 展开更多

Background: Knee range of motion is an essential outcome measure following total knee arthroplasty and it is important to measure this outcome with a simple and accurate tool. Measurement from digital photographs could provide a superior clinical alternative to the common goniometer as devices for capturing digital photographs are becoming more accessible, measurement accuracy is assisted with the associated software and images can be saved and stored for later reference. This ability to store images with measurements could be particularly useful in research involving knee range of motion. This study evaluated the validity and reliability of a simple photographic measurement technique to measure knee flexion and extension of patients following knee arthroplasty.Methods: Knee flexion and extension of 38 subjects who had undergone total knee arthroplasty were assessed at the one year post-operative review with the digital technique and a universal goniometer as the criterion reference. Digital measurements were repeated one month later by the first assessor (intra-tester reliability) and another independent assessor (inter-tester reliability).Results: Validity: the digital technique was found to have a high level of agreement with the universal goniometer measurements (all MAD sion with almost perfect Intra-Class Correlations (Intra-tester;flexion 0.99, extension 0.96;inter-tester;flexion 0.97, extension 0.93).Conclusion: Measurement of knee range of motion from digital photographs can be used in routine clinical total knee arthroplasty follow-up instead of, or interchangeably with the universal goniometer. 展开更多

The purpose of this study is to investigate a new method for measuring shoulder range of motion (ROM) in an orthopedic practice utilizing a smartphone application to improve accuracy from physical exam typically used in research. Our aim is to evaluate the application, Physio2Go (P2G), which uses a virtual goniometer, assessing validity by comparing its measurements to those taken by a universal goniometer (UG). Two observers of varying clinical experience, a research assistant and research fellow, compared measurements. Statistically, we used the intra-class correlation coefficient (ICC), standard error of measurement (SEM), and the Pearson correlation coefficient (PCC). Following validation we tested P2G in symptomatic postoperative shoulder patients measuring forward flexion (FF) and external rotation (ER). We compared P2G measurements to visual estimation (VE) done by a fellowship trained orthopedic surgeon. Statistically we used ICC, Bland- Altman plots with 95% limits of agreement (LOA), and scatter plots. We examined the impact of the application using Welch’s t-test comparing pre-to-postoperative ROM improvements using the values obtained by P2G and VE. We found high intra-rater reliability of P2G for both observers, substantial correlation between UG and P2G measurements, highly correlated inter-observer reliability for UG and P2G, and statistically significant PCC values (p < 0.05). As expected, ROM measurements of symptomatic patients comparing P2G and VE measurements demonstrated lower correlation. Bland-Altman plots demonstrated wide confidence intervals;scatterplots and histograms confirmed low agreement among measurement methods. Clinical application demonstrated varying statistical significance depending on whether measurements were done by P2G or VE. Our study found that P2G provided superior reliability compared to the customary physical exam routinely used for orthopedic research. The value of using this application instead of a UG is the ease of use and the ability for any member of the healthcare team, regardless of clinical experience to be able to produce reliable and valid measurements. 展开更多

Background: Multiple level anterior cervical discectomy and fusion (ACDF) is indicated for those who suffer from multilevel stenosis or compression of the spinal canal. It was reported that this intervention would unfortunately lead to a loss of normal cervical range of motion (CROM). Although, fewer studies have demonstrated the exact impact of the procedure on CROM. In our study, short and midterm postoperative CROM was described. Methods: Ninety patients who underwent ACDF were followed up postoperatively for at least 3 months. Active CROM was measured in all patients preoperatively and in postoperative follow-ups by cervical spine X-rays in lateral dynamic view using Cobb’s angle method. Results: Unfortunately, postoperative CROM was significantly diminished. At the short-term (3 months) follow-up there was a great limitation in CROM. While an obvious increase in CROM at the midterm (6 months) follow-up was observed in flexion especially. The reduction in global ROM (calculated as preoperative global ROM – 6 months postoperative ROM) was 4.1 and the reduction rate (calculated as reduction ROM divided by preoperative ROM) was 9.5%. The recovery ROM (calculated as 6 months postoperative ROM – 1 month postoperative ROM) was 8.2. The recovery rate (calculated as recovery ROM divided by 1 month postoperative ROM) was 26.5%. Conclusion: Active CROM following multiple level ACDF was obviously diminished. The most affected motion after surgery was flexion. It was noticed that at the short-term follow-up CROM would be more limited while after further follow up CROM was obviously improved even in neck flexion motion. 展开更多

The aim of this study was to characterize the obesity effect on children knee and hip joint range of motion. A randomized controlled trial was performed with goniometry evaluation for hip flexion, extension, abduction, adduction, external and internal rotation, and knee flexion in fifty male children (20 obese and 30 non obese), with age ranging from 6 to 12 years old. The obesity effect was found to be non-uniform across the joint range of motion. In the obesity group, a statistically significant reduction in the range of motion of hip flexion and adduction, and knee flexion was observed;and also an increase in external rotation in the hip was observed. Conclusion: Obese and overweight children present alterations in hip and knee joints mobility when compared to eutrophic children. The obesity/overweight associated with factors previously described in the literature, such as joint overload, postural deviation and sedentariness may influence the musculoskeletal development and, consequently, the motor function. 展开更多

BACKGROUND In the field of minimally invasive surgery(MIS)for the treatment of hallux valgus(HV),different techniques have begun to emerge in the literature concerning the distal osteotomy of the first metatarsal bone,the synthesis or not of the metatarsal head,the possible association with lateral soft tissues release(LSTR)and osteotomy of the base of the first phalanx.AIM To evaluate the role of LSTR on percutaneous HV correction,evaluating functional and radiographical results.METHODS From January 2012 to May 2016 a total of 396 patients with mild to moderate symptomatic HV treated with the MIS technique were included in this retrospective study.The technique provides no internal fixation(WOS).Patients were divided into the LSTR group and no LSTR group(LSTR N).This surgical procedure(LSTR)was reserved for insufficient HV angle(HVA)correction during fluoroscopic control.Patients were evaluated at each follow-up by two other authors after appropriate training by senior authors(first practitioners).Clinical evaluation was performed before surgery,6 mo after surgery,and 48 mo follow-up.American Orthopaedic Foot and Ankle Society(AOFAS)and visual analog scale(VAS)score was used to evaluate pain and function,and complications were recorded.In addition,the incidence of relapses and the degree of joint range of motion(ROM)with the association with the LSTR(capsule,adductor tendon,phalanx-sesamoid ligament,and the deep transverse metatarsal ligament)were evaluated.Radiological parameters included HVA and intermetatarsal angle(IMA).Patient satisfaction was assessed.Student t-test and Fisher exact test were used to assess statistical analysis.RESULTS From our study it is clear that no differences in term of HVA,VAS,IMA correction,rate of complications,and AOFAS score were found between groups,while a significant improvement of the same variables was found in each group between pre and postoperative values.A significant improvement in ROM at 6 mo(P=0.018)and 48 mo(P=0.02)of follow-up was found in LSTR N group.Complications were rare in both groups.CONCLUSION LSTR procedure on percutaneous HV correction seems to increase postoperative joint stiffness with a comparable incidence of relapse and a low incidence of complications. 展开更多

To study the influence of head-neck ratio and implant position on the range of motion (ROM) after total hip arthroplasty (THA).Methods In this study the author established a three-dimensional computerized model of hip joint and tested the range of motion of three different head-neck ratio after total hip arthroplasty.Results Range of motion after total hip arthroplasty depended on design parameters such as head-neck ratio,but also on the implantation parameters such as the cup’s inclination and antevertion,the stem’s antevertion and their combination of each other.Optimal range of motion required compliant position of total hip components.The range of motion increased with the enlarging of head-hnck ratio.Conclusion Higher head-neck ratio leads to optimal range of motion and decreased the prevalence of prosthetic impingement within compliant,well-defined combination of cup’s inclination,cup’s antevertion and stem’s antevertion depending on the intended ROM.Domestic magnesium-silicon jade total hip prosthesis has too low head-neck ratio to result in enough range of motion that fulfilled daily living after total hip arthroplasty.14 refs,4 figs,3 tabs. 展开更多
