Background: The lack of patient compliance with upper limb bracing results in delayed healing, progression of deformity, and sometimes even permanent disability. Common upper limb musculoskeletal disorders require bracing and physical therapy, but patient non-compliance with bracing is widespread. The study aims to identify the factors that result in non-compliance with upper limb bracing following physical therapy, thus affecting the patient’s recovery from injury. Methods: Across-sectional descriptive study ontotal of 300 patients between ages 20-50 was conducted at Centre of Benzair Bhutto Hospital. A self-designed questionnaire was used to evaluate the history and factors affecting patient compliance. Orthotic Prosthetic user survey form was used to assess non-compliance with the brace. Results: Out of a total of 300 patients,100 (33.3%) subjects correctly used the brace, 115 (38.33%) subjects did not use the brace, and 85 (28.33) subjects used the brace but did not use it as advised by the orthotist. Out of 115 non-users, 75 patients could not afford the brace, and 40 patients thought they were improving with physiotherapy, so there was no need to use the brace. The most common factors affecting patient compliance with bracing following physiotherapy are either the brace being uncomfortable (36.4%) or discomfort at night (18.8%). Conclusion: Patient’s compliance was reported following physiotherapy, though the participants were reluctant to use the brace due to highcost and discomfort. Efforts to decrease the cost of brace, and discomfort may be beneficial in increasing compliance with bracing treatment following physiotherapy.

BackgroundTemporomandibular disorders (TMDs) pose diagnostic challenges, and selecting appropriate imaging modalities is crucial for accurate assessment. This study aimed to compare the diagnostic accuracy and efficacy of ultrasonography (US) and magnetic resonance imaging (MRI) in identifying TMDs.MethodsA comprehensive meta‐analysis was conducted, including studies that compared US and MRI for TMJ disorder assessments. Fixed‐effects models were utilized to calculate pooled odds ratios (ORs) and relative risks (RRs) with 95% confidence intervals (CIs). Heterogeneity was assessed using the chi‐squared test and I2 statistic. Newcastle–Ottawa scale was used to assess the methodological quality of the studies included.ResultsSix studies were included, involving a total of 281 participants. The meta‐analysis demonstrated that MRI was statistically somewhat better than US in identifying TMJ disorders. The summary OR was 0.64 (95% CI: 0.46–0.90), and the summary RR was 0.80 (95% CI: 0.68–0.95). Heterogeneity among the studies was low (χ2 = 2.73, df = 5, p = .74; I2 = 0%). Demographic variables revealed variations in sample size, gender ratio and mean age across the studies.ConclusionThis meta‐analysis provides evidence that MRI may be more effective than US in diagnosing TMDs. However, the study is limited by the small number of included studies and variations in demographic variables and study designs. Future research with larger samples and standardised protocols is essential to confirm and strengthen these findings. Understanding the diagnostic accuracy of MRI and US for TMJ disorders will aid clinicians in making informed decisions for effective TMJ disorder assessments and patient management.

This paper investigated the feasibility of using 3D printing processes, specifically material extrusion (MEX) and vat photopolymerization (DLP—Digital Light Processing), to produce customized wrist–hand orthoses. Design, printability, and usability aspects were addressed. It was found that minimizing printing time for orthoses with intricate shapes, ventilation pockets, and minimal thickness is difficult. The influence of build orientation and process parameters, such as infill density, pattern, layer thickness, and wall thickness, on printing time for ten parameter configurations of orthoses in both ready-to-use and flat thermoformed shapes was examined. The findings revealed that the optimized orientations suggested by Meshmixer and Cura (Auto-orient option) did not reliably yield reduced printing times for each analyzed orthoses. The shortest printing time was achieved with a horizontal orientation (for orthoses manufactured in their ready-to-use form, starting from 3D scanning upper limb data) at the expense of surface quality in contact with the hand. For tall and thin orthoses, 100% infill density is recommended to ensure mechanical stability and layer fill, with caution required when reducing the support volume. Flat and thermoformed orthoses had the shortest printing times and could be produced with lower infill densities without defects. For the same design, the shortest printing time for an orthosis 3D-printed in its ready-to-use form was 8 h and 24 min at 60% infill, while the same orthosis produced as flat took 4 h and 37 min for the MEX process and half of this time for DLP. Usability criteria, including perceived immobilization strength, aesthetics, comfort, and weight, were evaluated for seven orthoses. Two healthy users, with previous experience with traditional plaster splints, tested the orthoses and expressed satisfaction with the 3D-printed designs. While the Voronoi design of DLP orthoses was visually more appealing, it was perceived as less stiff compared to those produced by MEX.
