Purpose: Despite repetitive activities and the frequency of high workload for municipal solid waste (MSW) collectors, the risks of work-related stress on upper extremity pain are inconclusive. The objective of this study is to assess the moderation and mediation effect of effort-reward imbalance (ERI) and over-commitment (OC) on upper back and hand/wrist disorders in MSW collectors.
Methods: A cross-sectional study was conducted with MSW collectors from two cities in Taiwan. Each participant was asked to anonymously fill out a structured questionnaire. Work-related stress, including ERI and OC, was assessed by a Chinese version of the Job Content Questionnaire (C-JCL). Upper back and hand/wrist disorders were assessed using the Nordic musculoskeletal questionnaire. Multivariate analysis was used to assess moderation and mediation effect of OC and ERI on upper extremity pain.
Results: The moderation effect of ERI and OC on upper back and hand/wrist disorders in MSW collectors was found. Disorders were higher in the group with both ERI ≥1 and high OC (OR (odds ratio) = 3.25 and OR = 3.00) than in the group with ERI ≥1 and low OC (OR = 2.66 and OR = 1.87) and in the ERI <1 and high OC group (OR = 2.27 and OR = 1.26). Synergy indexes were 0.77 and 1.77, respectively. Using multivariate analysis after adjusting for covariates, the mediation effect of OC was significant for the association between ERI and upper back and hand/wrist pains. The indirect effects of OC for upper back and hand/wrist pains accounted for 35% and 42%, respectively, and OC appears to mediate the relationship between ERI and upper back and hand/wrist disorders in MSW collectors.
Conclusion: Work-related stress measured ERI and OC may play a role in moderating and mediating effects on upper extremity pain. Encouraging provisions of work modification and stress management is needed to mitigate the occurrence of upper extremities pain in MSW collectors.

Effectiveness of a scapular exercise program on functional outcomes in patients with hand, wrist or elbow disorders: A comprehensive systematic review with meta-analysis.

Background: Usually, patients with hand, wrist/forearm disorders report musculoskeletal complaints in the shoulder. Although, role of scapula is fundamental for movement and functional stability across the upper limb kinetic chain; however, there are no systematic reviews and meta-analyses that have analyzed the effect of scapular exercises in these patients.
Purpose: This study aimed to determine the effectiveness of a scapular exercise program on functional outcomes in patients with hand, wrist or elbow disorders.

Article Synopsis
- Deep neural networks (DNNs) and transfer learning (TL) are used to enhance force estimation from surface electromyograms (sEMG), but previous research mainly focused on a single joint, limiting data diversity.
- This study explored cross-joint TL between two upper-limb joints using four DNN models, finding that 400 ms is sufficient to capture important sEMG-force relationships, suggesting simpler models may work effectively.
- Fine-tuning a model pre-trained on elbow data with hand-wrist data improved accuracy and reduced training data needs, with a convolutional neural network achieving a significant lower error rate compared to other models.
Prevalence and Practice Characteristics of Advanced Practice Providers in Upper-Extremity Surgery, 2013-2021.
J Hand Surg Am

Article Synopsis
- The study assessed the prevalence and characteristics of advanced practice providers (APPs) like nurse practitioners and physician assistants who treat hand, wrist, and upper extremity conditions in the U.S. from 2013 to 2021.
- It analyzed Medicare data to track diagnostic and therapeutic services these providers offered in comparison to traditional surgeons.
- The findings revealed a significant increase (170.9%) in APPs providing upper-extremity care over the years, indicating a rising reliance on these practitioners amid expected surgeon shortages.

Musculoskeletal Disorders (MSDs) stand as a prominent cause of injuries in modern agriculture. Scientific research has highlighted a causal link between MSDs and awkward working postures. Several methods for the evaluation of working postures, and related risks, have been developed such as the Rapid Upper Limb Assessment (RULA).

Article Synopsis
- - Occupational hand and wrist injuries (OHWIs) represented 20.3% of 2,101 work-related accidents treated in a Colombian hospital, predominantly affecting men aged around 31, especially in the mining industry.
- - Most injuries involved the right upper extremity, with common types including contusions (42.1%) and lacerations (27.9%), primarily impacting the phalanges of the first finger.
- - The study highlights the need for targeted preventive measures for specific risk groups, particularly for male miners in Cundinamarca, who face longer rehabilitation and potential permanent limitations due to OHWIs.
