The Effectiveness of Physiotherapy Rehabilitation in an Adult With Multiple Joint Fractures - A Case Report.

This case report details the rehabilitation procedure for a 35-year-old man involved in a vehicle accident that resulted in multiple joint fractures. The patient had fractures to the proximal tibia, left bimalleolar, posterior malleolus, fourth and fifth metacarpal heads, and second and third proximal phalanges. After open reduction and internal fixation surgery, an 8-12 week physical treatment regimen was put into place. Exercises for both passive and active range of motion, isometric and progressive resistance training, and gait training were provided. The rehabilitation goals were pain relief, increased range of motion, muscle strength, flexibility, endurance, and functional independence. Pain levels, range of motion, muscle strength, and general function all significantly improved between pre- and post-rehabilitation evaluations. Early mobilization and structured physical therapy were crucial in achieving these outcomes, highlighting the importance of tailored rehabilitation protocols for post-operative recovery.

Percutaneous Coracohumeral Release for Patients with Adhesive Capsulitis: Two-Year Results from a Randomized Control Crossover Study.

BACKGROUND: Adhesive capsulitis (AC) causes a variety of symptoms, including but not limited to pain, stiffness, and a gradual restriction of active and passive range of motion (ROM). The coracohumeral ligament (CHL) plays an important role in this disease process, and percutaneous CHL release (PCHLR) has demonstrated efficacy in treating manifestations of this disorder that are refractory to pain medication, physical therapy, and local injections. Our previous study demonstrated one-year efficacy and durability, and this study examines 2-year data from our original randomized control crossover cohort. OBJECTIVE: To highlight the importance of extended follow-ups evaluating PCHLR's efficacy in AC management. STUDY DESIGN: A prospective, randomized, controlled, cross-over trial. SETTING: An academic medical center. METHODS: Patients with AC refractory to oral medication, physiotherapy, and at least one local injection were included in our original study. In all, there were initially 40 patients (46 shoulders), including 6 patients who underwent bilateral PCHLR using the Tenex® system. In this prospective study, 2 groups, the experiment group (scheduled to receive PCHLR) and the control group (scheduled to receive a local anesthetic in the coracohumeral ligament [LACHL]) were determined through 2-to-1 block randomization. Of these 46 shoulders initially treated, 39 remained in the study at one year. Twenty-six of the 39 shoulders were assigned to the PCHLR group whereas 13 were assigned to the LACHL group. Nine out of 13 shoulders in the LACHL group crossed over to the PCHLR group. Ultimately, 31 shoulders remained in the PCHLR group for 2-year analysis. The effectiveness of these interventions was assessed using a variety of parameters. Pain scores, ROM, and the Oxford Shoulder Score (OSS) were evaluated before the procedure and at one-year and 2-year follow-up visits. RESULTS: In this 2-year follow-up study, a total of 31 shoulders were sampled, comprising 22 women and 5 men, with 4 patients undergoing bilateral procedures. The mean age of the patients was 65 years (± 11.48). Patients' mean body mass index (BMI) was 36.33 (± 6.55), and the mean CHL thickness was 38.5 (± 3.45). Osteoarthritis was present in 11 cases. The mean follow-up period for the study was 29.7 months (± 6.39). The baseline mean external rotation was 30° (± 8), which increased to 62° (± 18) at one year and 53° (± 18) at 2 years. The baseline mean abduction was 60° (± 16), which improved to 77° (± 21) at one year and 68° (± 20) at 2 years. The median NRS decreased from 8 (IQR: 8, 9) at baseline to 3 (IQR: 2, 7) at one year and 5 (IQR: 2, 7) at 2 years. The baseline median OSS was 7 (IQR: 3, 10), which increased to 32 at one year and 22 (IQR: 15, 35) at 2 years. LIMITATIONS: The present investigation has a limited sample size of patients who have ROM impairment caused by CHL thickening. CONCLUSIONS: While the algorithm for AC care has seen little change for several decades, the authors suggest that PCHLR is a safe, durable, and effective option for cases of AC that are refractory to traditional management.

Comparison of wrist range of motion and muscle strength in assembly workers with and without lateral epicondylitis.

BACKGROUND: Lateral epicondylitis (LE), also called tennis elbow, is a common musculoskeletal disorder that causes pain in the elbow area and is highly prevalent in assembly workers who repeatedly move their wrists. OBJECTIVE: The purpose of this study was to compare the wrist ROM and muscle strength of assembly workers with and without LE. METHODS: Forty-five male assembly line workers (23 with LE) participated in the study. Participants had their wrist range of motion (flexion, extension, ulnar deviation, and radial deviation) and strength (wrist flexors, extensors, and hand grip) measured using Smart KEMA sensors. RESULTS: Workers with LE showed significantly reduced wrist extension and radial deviation ROM compared to workers without LE, with no significant differences in wrist flexion and ulnar deviation ROM between groups. Workers with LE had significantly lower wrist extensor strength compared to workers without LE, and there was no significant difference in wrist flexor and grip strength between the two groups. CONCLUSIONS: For workers with LE, the difference in wrist ROM and muscle strength will be useful for planning intervention and evaluating treatment outcomes for assembly workers with LE.

CT-based comprehensive scoring system for assessing hip arthropathy in ankylosing spondylitis: feasibility study with clinical correlation.

OBJECTIVE: To develop a CT-based scoring system for assessment of hip arthropathy in AS. METHODS: All AS patients were prospectively recruited, consented, and underwent whole-body stereoradiographs and pelvis CT, which were assessed by two independent radiologists. Stereoradiographs were assessed according to Kellgreen-Lawrence and BASRI-h. For the Hip arthropathy CT score in AS (HACTSAS), joints were divided into 7 segments and scored for joint space, osteophytes, subchondral cysts/erosions. Patients were clinically assessed for range of motion (ROM), pain, and clinical scores (BASMI, BASFI, ASQol, BASDAI and ASDAS). Radiological scores correlations with clinical parameters were compared. ROM sensitivity and specificity for hip arthropathy (BASRI-h ≥ 2) were calculated. RESULTS: Sample included 112 patients, with 36/112 females and 76/112 males. Average age was 51.0 ± 11.2 years and mean duration of AS was 20.9 ± 9.6 years. ICC for HACTSAS, Kellgreen-Lawrence and BASRI-h were 0.89, 0.89 and 0.82 respectively. HACTSAS showed moderate absolute correlation with ROM (ρ=-0.41) and BASMI (ρ = 0.45), and weak with pain (ρ = 0.18) and BASFI (ρ = 0.25). BASRI-h and Kellgreen-Lawrence exhibited moderate correlation with ROM (ρ=-0.44 and ρ=-0.40, respectively), weak with pain (ρ=-.27and ρ=-0.23, respectively) and BASFI (ρ=-0.16 and ρ=-0.18, respectively), but only weak with BASMI (ρ=-0.34 and ρ=-0.36, respectively). Internal rotation <15°, abduction <31°, and intermalleolar distance <75cm were, respectively, 73%, 70% and 73% sensitivity and 81%, 65% and 68% specific for hip arthropathy. CONCLUSION: HACTSAS exhibited higher correlation with BASMI and BASFI when compared with BASRI-h, but less correlation with pain and ROM. Internal rotation was the best clinical discriminator for hip arthropathy.

The pilot study of the effect of six-week robot-assisted ankle training on mobility and strength of lower extremity and life habits for children with cerebral palsy.

Background: Children with cerebral palsy often have weak ankle muscles and reduced ankle dorsiflexion, which leads to activity limitations and eventually affects quality of life. Robotic ankle training was recently developed to facilitates muscle function through a high repetition of exercises. This study investigated the effect of six-week ankle training using the Anklebot device to improve lower limb structural and functional impairments and the resulting impact on quality of life. Methods: Five children with spastic cerebral palsy aged between 4 and 11 years participated in six weeks of bilateral ankle assistive training using the Anklebot device. All lower limb muscle strength was measured with a hand-held dynameter, and range of motion was measured with a goniometer, at four different time points. Muscle architecture was assessed using a portable diagnostic ultrasound device, and quality of life was assessed using the Life Habits for Children scale, at two points in time only. Results: Muscle strength and range of motion for all lower limb joints demonstrated significant improvement on both sides after training. The ankle muscle architecture showed non-significant improvement, while an overall significant improvement in the total score of the Life Habits for Children scale was detected after training. Conclusion: Robot-assisted task-specific ankle training provides promising effects by allowing the required repetition to improve structural and functional muscle and joint impairments, which has a positive influence on the children's quality of life. However, due to a limited sample size, these results should be considered as preliminary; further study is needed.

Effectiveness of mixed reality-based rehabilitation on hands and fingers by individual finger-movement tracking in patients with stroke.

BACKGROUND: Mixed reality (MR) is helpful in hand training for patients with stroke, allowing them to fully submerge in a virtual space while interacting with real objects. The recognition of individual finger movements is required for MR rehabilitation. This study aimed to assess the effectiveness of updated MR-board 2, adding finger training for patients with stroke. METHODS: Twenty-one participants with hemiplegic stroke (10 with left hemiplegia and 11 with right hemiplegia; nine female patients; 56.7 ± 14.2 years of age; and onset of stroke 32.7 ± 34.8 months) participated in this study. MR-board 2 comprised a board plate, a depth camera, plastic-shaped objects, a monitor, a palm-worn camera, and seven gamified training programs. All participants performed 20 self-training sessions involving 30-min training using MR-board 2. The outcome measurements for upper extremity function were the Fugl-Meyer assessment (FMA) upper extremity score, repeated number of finger flexion and extension (Repeat-FE), the thumb opposition test (TOT), Box and Block Test score (BBT), Wolf Motor Function Test score (WMFT), and Stroke Impact Scale (SIS). One-way repeated measures analysis of variance and the post hoc test were applied for the measurements. MR-board 2 recorded the fingers' active range of motion (AROM) and Dunnett's test was used for pairwise comparisons. RESULTS: Except for the FMA-proximal score (p = 0.617) and TOT (p = 0.005), other FMA scores, BBT score, Repeat-FE, WMFT score, and SIS stroke recovery improved significantly (p < 0.001) during MR-board 2 training and were maintained until follow-up. All AROM values of the finger joints changed significantly during training (p < 0.001). CONCLUSIONS: MR-board 2 self-training, which includes natural interactions between humans and computers using a tangible user interface and real-time tracking of the fingers, improved upper limb function across impairment, activity, and participation. MR-board 2 could be used as a self-training tool for patients with stroke, improving their quality of life. TRIAL REGISTRATION NUMBER: This study was registered with the Clinical Research Information Service (CRIS: KCT0004167).

The impact of glenohumeral bone loss on range of motion in patients with anterior shoulder instability.

BACKGROUND: Loss of shoulder range of motion (ROM) is common after surgical management of anterior shoulder instability; however, it remains unclear to what degree this is related to their injury. AIM: The purpose of this study was to compare passive shoulder ROM in patients with ASI to a normal contralateral shoulder. METHODS: A total of 121 patients undergoing stabilization surgery were prospectively enrolled. Preoperative advanced imaging was used to assess for glenoid bone loss and the presence of off-track Hill-Sachs lesions. Passive ROM was measured in both shoulders while under anaesthesia prior to surgery. RESULTS: In all directions, there was a significant loss of ROM in shoulders with instability. Regression analysis showed that neither a glenoid bone defect nor greater glenoid bone loss were associated with a loss of ROM in any plane. The presence of a Hill-Sachs lesion was significantly associated with a loss of external rotation, while off-track lesions were associated with a loss of ROM in all planes (p < 0.05). CONCLUSION: Patients with anterior shoulder instability lost motion in all directions, with a profound loss of external rotation. The presence of a glenoid bone defect nor greater bone loss did not reliably predict a loss of range of motion. A Hill-Sachs lesion was predictive of a loss of external rotation, while an off-track lesion was predictive of a loss of range in all directions.

Total Knee Arthroplasty in Patients Who Have Ankylosed Knees: A Ten-Year Retrospective.

INTRODUCTION: Knee ankylosis can result in major functional impairment, and surgical treatment of knee ankylosis is often regarded as a tremendous challenge due to technical difficulties such as difficult joint exposure and a high incidence of complications. The objective of this study was to review the results of preoperative and postoperative functional scores, range of motion (ROM), and complications of total knee arthroplasty (TKA) for the treatment of knee ankylosis. SURGICAL METHODS: Between January 2007 and January 2021, 19 patients (17 patients, 11 women, and 6 men) who had knee ankylosis underwent TKA. The mean age of the patients was 52 years (range, 31 to 71), and the mean follow-up period was 10.2 years (range, 3.1 to 13.9). The surgical procedure involved a total knee arthroplasty, performed via a medial parapatellar approach, a quadriceps snip, and a secondary osteotomy with soft-tissue release. The postoperative clinical outcomes and complications were evaluated using a range of methods, including ROM assessment, Hospital for Special Surgery Knee Score (HSS), and visual analogue scale (VAS) scores. RESULT: At final follow-up, the mean HSS score improved significantly from the preoperative score of (33.63 ± 8.69) to (88.05 ± 5.23) (P < 0.001), ROM improved from (0 ± 0°) to (100.90±14.07°) (P < 0.001), the VAS score improved from a preoperative score of 0 to (1.00 ± 0.94) (P< 0.001), and radiographs showed no aseptic loosening of the knee. There were eight knees (42.1%) that had postoperative complications. CONCLUSION: Total knee arthroplasty in patients who have ankylosing knees resulted in significant improvements in flexion and extension, mobility, and quality of life, despite a high incidence of complications such as skin necrosis.

Role of intra-lamellar collagen and hyaluronan nanostructures in annulus fibrosus on lumbar spine biomechanics: insights from molecular mechanics-finite element-based multiscale analyses.

Annulus fibrosus' (AF) ability to transmit multi-directional spinal motion is contributed by a combination of chemical interactions among biomolecular constituents-collagen type I (COL-I), collagen type II (COL-II), and proteoglycans (aggrecan and hyaluronan)-and mechanical interactions at multiple length scales. However, the mechanistic role of such interactions on spinal motion is unclear. The present work employs a molecular mechanics-finite element (FE) multiscale approach to investigate the mechanistic role of molecular-scale collagen and hyaluronan nanostructures in AF, on spinal motion. For this, an FE model of the lumbar segment is developed wherein a multiscale model of AF collagen fiber, developed from COL-I, COL-II, and hyaluronan using the molecular dynamics-cohesive finite element multiscale method, is incorporated. Analyses show AF collagen fibers primarily contribute to axial rotation (AR) motion, owing to angle-ply orientation. Maximum fiber strain values of 2.45% in AR, observed at the outer annulus, are 25% lower than the reported values. This indicates native collagen fibers are softer, attributed to the softer non-fibrillar matrix and higher interfibrillar sliding. Additionally, elastic zone stiffness of 8.61 Nm/° is observed to be 20% higher than the reported range, suggesting native AF lamellae exhibit lower stiffness, resulting from inter-collagen fiber bundle sliding. The presented study has further implications towards the hierarchy-driven designing of AF-substitute materials.

Cervical orthosis does not improve postoperative pain following posterior cervical fusion: a randomized controlled trial.

PURPOSE: To determine whether postoperative neck pain in the first 4 weeks following multi-level posterior cervical fusion (PCF) with orthosis is equivalent to multi-level PCF without orthosis. METHODS: Patients were randomly assigned in a 1:1 ratio to postoperative orthosis (CO) for 6 weeks or no orthosis (NO). Randomization was stratified by indication (traumatic vs. degenerative), and preoperative opioid use. A model of longitudinal regression for repeated measures was used. The two-sided 95% confidence interval (CI) was used to test equivalence. If the CI lay between the pre-determined margin of equivalence (-2.0 to + 2.0 pain score) the two groups were considered equivalent. A multiple imputation procedure was used to replace missing data. RESULTS: Thirty-one patients were enrolled in each group. At baseline, the CO group had more neck pain (5.3 vs. 3.2, p = 0.013). The Four week post-operative neck pain intensity score was 4.6 ± 0.3 for the CO group vs. 4.9 ± 0.3 for the NO group. The 95% confidence interval (-1.2 to 0.6) was within the pre-determined equivalence margin. Neck Disability Index, quality-of-life scores, and arm pain were similar. Eleven patients in the CO group and 12 patients in the NO group had an adverse event. The CO group had reduced range of motion at 6 weeks. CONCLUSION: Pain scores over the first 4 weeks after surgery were equivalent for patients undergoing multi-level PCF treated with or without a cervical orthosis. Our findings do not support the routine use of a postoperative cervical orthosis for postoperative pain control. Clinical Trials Registration Number NCT04308122, April 22, 2020.

Factors associated with patient-reported mouth opening activity limitations in individuals with persistent intra-articular temporomandibular disorders: A cross-sectional study exploring physical and self-reported outcomes.

BACKGROUND: Individuals living with intra-articular temporomandibular disorders (IA-TMDs) often report limitations with mouth opening activities. While clinical measures such as active range of motion (AROM) and movement quality are often used to assess mouth opening function, it is unclear if and how these relate to patient-reported limitations and whether other factors such as kinesiophobia influence mouth opening activities in those with IA-TMDs. OBJECTIVES: Compare clinical measures of mouth opening function in those with IA-TMDs to asymptomatic controls. In those with an IA/TMD, explore relationships between patient-reported mouth opening limitations, and mouth opening function and kinesiophobia. DESIGN: Cross-sectional study. METHOD: Clinical mouth opening function (AROM, movement quality, pain on movement/10, stiffness on movement/10) was compared between groups (n = 30 IA-TMD, n = 30 controls). Within the IA-TMD group, correlations between patient-reported mouth opening limitations (Patient specific functional scale), kinesiophobia (Tampa Scale for Kinesiophobia for Temporomandibular Disorders) and clinical measures of mouth opening function were explored. RESULTS: Impairments in AROM (-4 mm, p = 0.04, d = 0.5), movement quality (p < 0.01, φ = 0.6), pain on movement (p < 0.01, d = 0.8) and stiffness on movement (p < 0.01, d = 1.6) were observed in the IA-TMD group compared to controls. Patient-reported mouth opening limitations and kinesiophobia were significantly correlated (r = -0.48, p < 0.01); no correlation was found between patient-reported limitations and clinical mouth opening measures (r < 0.3, p > 0.05). CONCLUSIONS: Mouth opening function is impaired in IA-TMD. However, kinesiophobia appears more related to patient-reported mouth opening limitations than clinical impairments. Consideration of clinical, kinesiophobia and patient-reported limitation measures are necessary to direct management of IA-TMD in those presenting for care.

The Short-Term Efficacy of Integrating the Easy-Flex Device with Inpatient Rehabilitation in Total Knee Arthroplasty Patients: Insights from a Single-Blind Randomized Controlled Trial.

OBJECTIVE: To determine the effect of Easy-Flex as an adjunct to standard inpatient rehabilitation on clinical and functional outcomes. DESIGN: Prospective randomized controlled trial SETTING: Outpatient clinic and research laboratory PARTICIPANTS: A total of 44 patients were randomized to the Easy-Flex Group (EFG) or Control Group (CG). INTERVENTION: A rehabilitation program averaging 50-60 minutes per day was implemented for the CG patients. In the EFG, in addition to 30-40 minutes of exercise with the Easy-Flex, the rehabilitation program applied to the CG was integrated with reduced sets and repetitions, with an average duration of 20 minutes. All interventions were performed under the supervision of a physiotherapist during hospitalization. After discharge, both groups received the same home exercise program. OUTCOME MEASUREMENTS: The primary outcome is the flexion and extension range of motion (ROM). The secondary outcomes include the Numeric Pain Rating Scale (NPRS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), Five Times Sit-to-Stand Test (5TSST), 10-Meter Walking Test (10MWT), Short Form-12v2, and Global Rating of Change score (GRCS). RESULTS: After 6 weeks, the overall group-by-time interaction for the 2 × 3 mixed-model ANOVA was found to be significant for flexion ROM (p=0.005), NPRS-rest (p=0.04), NPRS-activity (p=0.01), 10-MWT (p=0.003), WOMAC (p=0.021) and SF-12-PCS (p=0.032) in favor of EFG exercising with Easy-Flex in addition to standard rehabilitation. The between-group differences in favor of the EFG were -8.0° knee ROM, 1.35 to 1.5 points for pain intensity, and 0.12 m/sec for gait speed. Furthermore, differences favouring EFG in NPRS-rest,10-MWT speed, and SF-12 PCS were greater than the reported MCID. CONCLUSIONS: Incorporating Easy-Flex into standard physical therapy can be a beneficial, safe, and effective approach in clinical practice, as patients undergoing TKA typically prioritize improving their quality of life by reducing pain and increasing ROM.

Residual kinematic deviations of the shoulder during humeral elevation after conservative treatment for mid-shaft clavicle fractures.

Despite residual functional deficits clinically observed in conservatively treated mid-shaft clavicle fractures, no study has reported a quantitative assessment of the treatment effects on the kinematics of the shoulder complex during functional movement. Using computerised motion analysis, the current study quantified the 3D residual kinematic deviations or strategies of the shoulder complex bones during multi-plane elevations in fifteen patients with conservatively treated mid-shaft clavicle fractures and fifteen healthy controls. Despite residual clavicular malunion, the patients recovered normal shoulder kinematics for arm elevations up to 60° in all three tested planes. For elevations beyond 60°, normal clavicle kinematics but significantly increased scapular posterior tilt relative to the trunk was observed in the patient group, leading to significantly increased clavicular protraction and posterior tilt relative to the scapula (i.e., AC joint). Slightly different changes were found in the sagittal plane, showing additional changes of increased scapular upward rotations at 90° and 120° elevations. Similar kinematic changes were also found on the unaffected side, indicating a trend of symmetrical bilateral adaptation. The current results suggest that shoulder kinematics in multi-plane arm elevations should be monitored for any compromised integrated motions of the individual bones following conservative treatment. Rehabilitation strategies, including muscle strengthening and synergy stability training, should also consider compensatory kinematic changes on the unaffected side to improve the bilateral movement control of the shoulder complex during humeral elevation.

The Role of Humeral Torsion on Glenohumeral Rotation in Injured Baseball Players.

Background: Differences in rotational range of motion (ROM) compared to humeral retrotorsion (HRT)-corrected rotational ROM exist in healthy baseball athletes, but it is unclear whether these differences exist in a pathological population. Purpose/Hypothesis: The purpose of this study was to determine if there are disparities between objectively measured differences in ROM and HRT-corrected deficits in injured baseball players. It was hypothesized that disparities would exist between (1) the side-to-side difference in glenohumeral external rotation (GER) and the HRT-corrected glenohumeral external rotation deficit (GERD) and (2) the side-to-side difference in glenohumeral internal rotation (GIR) and the HRT-corrected glenohumeral internal rotation deficit (GIRD). Study Design: Cross-sectional study; Level of evidence, 3. Methods: Data from 172 baseball players with shoulder or elbow injuries (45 shoulder, 127 elbow) were reviewed in July 2023. GER and GIR were measured on the injured and noninjured sides of all players, and diagnostic ultrasound was used to measure HRT. Dependent t tests were run to compare the side-to side differences in GER and GIR with the HRT-corrected GERD and GIRD, respectively. Results: In the players with a shoulder injury, there was a significant disparity between the side-to-side difference in GER and the HRT-corrected GERD (2°± 14° vs -13°± 15°, respectively) and between the side-to-side difference in GIR and the HRT-corrected GIRD (-14°± 8° vs 2°± 9°, respectively) (P < .001 for both). Similarly, players with an elbow injury had significant disparities between the side-to-side difference in GER and the HRT-corrected GERD (6°± 9° vs -10°± 9°, respectively) and between the side-to-side difference in GIR and the HRT-corrected GIRD (-12°± 8° vs 4°± 10°, respectively) (P < .001 for both). Conclusion: The results supported our hypothesis that there were disparities between objectively measured differences in GER and GIR compared with the HRT-corrected GERD and GIRD in injured baseball players. Consideration must be given to osseous adaptations that occur at the glenohumeral joint when evaluating and treating this population.

Effectiveness of Delayed Surgical Treatment for Distal Radius Fractures With Loss of Reduction.

PURPOSE: This study investigated the effectiveness of volar plate surgery in patients with distal radius fractures (DRFs) initially treated nonsurgically but later experiencing reduction loss during follow-ups. Specifically, it assessed the impact of early surgery (E) (<3 weeks) versus delayed surgery (D) (3-6 weeks) on wrist function in surgically treated DRFs. METHODS: This retrospective study included 131 patients who underwent surgery after loss of reduction. Among them, 42 patients had delayed surgery, whereas 89 received early surgical treatment. The mean follow-up duration was 18 months. The primary outcome measure was Disabilities of the Arm, Shoulder, and Hand scores. Secondary outcomes included Short Form-12 physical component summary and mental component summary scores, postoperative range of motion, and radiological measurements such as radial length, radial inclination angle, and volar tilt angle. Fracture types were categorized using Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association classification based on radiological images. RESULTS: All 131 DRFs achieved radiological union. Mean Disabilities of the Arm, Shoulder, and Hand scores were 8.0 (range, 0-78) and 10.8 (range, 0-73) for groups E and D, respectively, and the difference was not considered clinically relevant. Short Form-12 physical component summary scores (49.4 for E; 45.3 for D) and Short Form-12 mental component summary scores (52.3 for E; 53.5 for D) were similar in the two groups. Radiological measurements and range of motion were similar in the two groups. Complications, including carpal tunnel syndrome, superficial radial nerve neuropraxia, and complex regional pain syndrome, occurred in 12 (13.5%) E group patients and 9 (21.4%) D group patients. CONCLUSIONS: Clinical and radiological results of early and delayed surgery after loss of reduction in secondary displaced DRF were similar. However, complication rates were higher in delayed surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Aerobic Training and Ointment Effect on range of motion, von Willebrand factor, vascular endothelial factor and Femoral Artery Hemodynamics in Joint Contracture: A Rat Model.

OBJECTIVE: Using a rat model, we investigated the effect of multidisciplinary rehabilitation, including aerobic training and ointment, on the ROM, vWF, VEGF content, and femoral artery hemodynamics in rats with joint contracture. METHODS: A total of 44 Wistar rats were divided into the normal control group (NC, eight rats) and the experimental group (EG). A joint contracture model was established for the rats in the EG group by an external fixator. After fixator removal, 32 rats are further divided into the MC, SC, RE, and SR groups (n = 8). Before and after the 42 day intervention, the ROM, vWF, VEGF, PS, ED, and RI were measured using X-ray imaging, ELISA, and color Doppler ultrasound, respectively. RESULTS: After fixator removal, ROM for EG group was lower than that of the NC group (p < .01). After the intervention, ROM for the SR, RE, and SC groups was improved. The ROM for the SR group reached a similar value for NC group. vWF and VEGF levels in SR group were lower than in the MC, SC, and RE groups (p < .05), and had a similar value to the NC groups. PS value for SR and RE groups was higher than the MC and SC groups. The RI value for SR group was higher than that of NC and MC groups. CONCLUSION: Multidisciplinary rehabilitation used in this study can treat joint contracture synergistically. It improves the ROM of the joint, reduces the content of vWF and VEGF, and improves the femoral artery hemodynamics.

Development and Validation of a Mobile Phone Application for Measuring Knee Range of Motion.

BACKGROUND: Knee range of motion (ROM) is an important indicator of knee function. Outside the clinical setting, patients may not be able to accurately assess knee ROM, which may impair recovery following trauma or surgery. This study aims to validate a smartphone mobile application developed to measure knee ROM compared to visual and goniometer ROM measurements. METHODS: A knee ROM Android mobile application was developed to measure knee ROM. Patients ≥ 18 years old presenting to an orthopedic clinic with native knee complaints were approached to participate. Knee ROM was measured bilaterally by an arthroplasty-trained surgeon using 1) vision, 2) goniometer, and 3) the mobile application. Measurements were compared in flexion and extension using a one-way ANOVA with post-hoc Tukey test (alpha = 0.05). RESULTS: 84 knee ROM measurements (40 left, 44 right) were obtained in 47 patients. Median Kellgren-Lawrence grade from available radiographs was grade 3. In flexion, mobile application (117.6 ± 14.7°) measurements were not significantly different from visual (116.1 ± 13.6°) or goniometer (116.2 ± 13.6°) measurements. In extension, mobile application (4.8 ± 7.3°) measurements were significantly different from visual (1.9 ± 4.1°) measurements on post-hoc analysis (p < 0.01), while no differences were present compared to goniometer (3.1 ± 5.8°) measurements. CONCLUSION: Our study found that a mobile application for evaluating knee ROM was non-inferior to goniometer-based measurements performed by an arthroplasty-trained surgeon. Future studies will investigate this application's utility in 1) remote patient care, 2) accelerating recovery during rehabilitation, 3) detecting early postoperative complications including arthrofibrosis, and 4) adding additional functionalities to the application to provide more detail-oriented descriptive analyses of patient knee function.

Non-operative management of metacarpal II-IV fractures: A retrospective study from a tertiary hand unit.

Metacarpal fractures produce significant hand disability, and non-operative management of these fractures can produce satisfactory functional outcomes with few complications. However, most studies assessing non-operative outcomes of metacarpal fractures revolves around metacarpals I and V, which possess different anatomy. Therefore, further investigation into outcomes after non-operative treatment of metacarpals II-IV is required to inform management decisions and allow modification of the rehabilitation protocols to specific fracture patterns. All records for 76 non-operative patients presenting with fractures of metacarpals II-IV to our tertiary centre in the year 2019 were retrospectively reviewed. Patients were treated with thermoplastic splinting or fibreglass casting with a rehabilitative exercise programme. Range of motion (ROM) of the Metacarpophalangeal (MCPJ), Proximal Interphalangeal (PIPJ), and Distal Interphalangeal joints (DIPJ), return to work time, and complications were assessed at 12 weeks post-treatment. Mean return to work time was 5.4 weeks, and patients did not report any serious adverse events; the main complication reported was tenderness on palpation (20%). The MCPJ exhibited the poorest ROM (9° flexion reduction relative to the healthy hand). Metacarpal II fractures were associated with significantly worse MCPJ flexion than metacarpal III (p = 0.022) and metacarpal IV (p = 0.049) fractures. Fractures of the metacarpal base were associated with superior MCPJ flexion (p = 0.004) but longer return to work time (p = 0.042) than head fractures. Spiral fractures were associated with shorter return to work time (p = 0.043) and superior ROM results (p = 0.041). In conclusion, outcomes of the non-operative treatment of metacarpal II-IV fractures are highly dependent on the location and pattern of the fracture, and this should be considered during clinical decision making.

Clinical application research of intelligent monitoring system for knee rehabilitation: a randomized controlled trial.

BACKGROUND: This study investigates the effectiveness of a self-developed intelligent monitoring system for home-based knee rehabilitation following total knee arthroplasty (TKA). METHODS: In this randomized controlled trial, 120 patients undergoing TKA were divided using random digit allocation. Preoperative and one-month postoperative assessments of knee function, quality of life, and isometric knee extension strength were conducted with the Intelligent Monitoring System. Patients received group-specific rehabilitation instructions pre-discharge and performed exercises for one month. RESULTS: Changes in isometric knee extensor strength on the affected side within one month post-surgery for the brace-monitored rehabilitation group showed a significant decrease three days after surgery compared to one day before surgery. Subsequent measurements taken at postoperative days 5, 7, 14, and 21 indicated a gradual increase in strength, although these increases did not reach statistical significance when compared with previous measurements. One month post-surgery, all groups demonstrated significant improvements in knee joint function and mobility compared to pre-surgery levels. Notably, the brace-monitored group showed statistically significant improvements in 36-Item Short-Form Health Survey (SF-36) scores over the conventional rehabilitation group. CONCLUSIONS: The Intelligent Monitoring System provides effective real-time monitoring and guidance for home-based knee rehabilitation post-TKA. It significantly enhances knee joint function, isometric knee extension strength, and quality of life shortly after surgery compared to traditional rehabilitation methods. This system offers a promising approach for improving postoperative recovery in TKA patients. TRIAL REGISTRATION: This study was approved by the Medical Ethics Committee of Xiangya Hospital, Central South University (Ethics Approval Number 202209008-2). It was registered with the China Clinical Trial Registry, a primary registry of the World Health Organization's International Clinical Trials Registry Platform (Registration Number ChiCTR2300068852).

Goniometry and fleximetry measurements to assess cervical range of motion in individuals with chronic neck pain: a validity and reliability study.

PURPOSE: To assess the test-retest and inter-rater reliability of goniometry and fleximetry in measuring cervical range of motion in individuals with chronic neck pain. METHODS: A reliability study. Thirty individuals with chronic neck pain were selected. Cervical range of motion was measured by goniometry and fleximetry at two time points 7 days apart. To characterize the sample, we used the numerical pain rating scale, Pain-Related Catastrophizing Thoughts Scale, and Neck Disability Index. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and minimum detectable change (MDC) were calculated. Correlations between goniometry and fleximetry measurements were performed using Spearman's correlation coefficient (rho). RESULTS: For goniometry, we found excellent test-retest reliability (ICC ≥ 0.986, SEM ≤ 1.89%, MDC ≤ 5.23%) and inter-rater reliability (ICC ≥ 0.947, SEM ≤ 3.91%, MDC ≤ 10.84%). Similarly, we found excellent test-retest reliability (ICC ≥ 0.969, SEM ≤ 2.71%, MDC ≤ 7.52%) and inter-rater reliability (ICC ≥ 0.981, SEM ≤ 1.88%, MDC ≤ 5.20%) for fleximetry. Finally, we observed a strong correlation between the goniometry and the fleximetry for all cervical movements (rho ≥ 0.993). CONCLUSION: Goniometry and fleximetry measurements are reliable for assessing cervical range of motion in individuals with chronic neck pain.
