Work-related upper limb disorders (WRULDs) are difficult to diagnose due to the limited availability of recognized objective assessment methods. This case series report demonstrates the use of the "typing capacity cycle" test and standardized clinical tests as outcome measures to assess work capacity in four high-intensity keyboard and mouse users who remain at work before and after the implementation of a six-month treatment program. Pain intensity, the duration of pain before treatment, the duration of treatment, type of work, and the location of the pain were recorded for each patient. Function was assessed before and after treatment using the Functional Grading Scale. The assessment results were analyzed to determine any improvements made after rehabilitation. The outcomes indicate that all patients improved their resting pain and work capacity with the three-phase rehabilitation program.

This study investigates the ergonomic assessment of sitting postures and the potential for work-related musculoskeletal disorders (WMSDs) in office environments by comparing traditional physical therapist evaluations with Inertial Measurement Unit (IMU) technology by determining the reliability and accuracy of sitting posture assessment using the rapid upper limb assessment (RULA) method. In this experiment, neck and body angle data is collected from twenty participants while sitting and working. The study aims to capture and compare the neck and trunk posture score based RULA protocol system to evaluate ergonomic risks.

Background: Firefighters are routinely exposed to significant work-related musculoskeletal disorders (WRMSDs) which can sometimes be career-ending due to the workplace stressors and the physical demands of the job. Shoulder disorders are the third most frequent WRMSDs that cause pain, disability, and morbidity in the general working population. However, little is known about the task-specific causes and risk factors for work-related shoulder disorders (WSDs) among firefighters (FFs).

Overuse injury is a frequent diagnosis in occupational medicine and athletics. Using an established model of upper extremity overuse, we sought to characterize changes occurring in the forepaws and forelimbs of mature female rats (14-18 months of age). Thirty-three rats underwent a 4-week shaping period, before performing a high-repetition low-force (HRLF) task for 12 weeks, with the results being compared to 32 mature controls.

The COVID-19 pandemic brought significant challenges across governmental, industrial, and social systems. Additionally, numerous studies have reported a sharp increase in both mental health issues and musculoskeletal disorders worldwide. This study aimed to investigate whether a specific exercise program could alleviate neck and upper back pain symptoms and improve mood state among healthcare and office employees during the post-COVID-19 period.

To accurately identify occupational health and safety hazards in different industries with distinct characteristics, a comprehensive occupational ergonomics assessment scale was developed by integrating the Rapid Upper Limb Assessment (RULA) evaluation framework, the Rapid Entire Body Assessment (REBA) and the Ovako Working Posture Analysing System (OWAS) . Between May 2023 and May 2024, based on the proportional reasoning method and segmented function method, the algorithm logic of RULA and REBA was aligned, and the evaluation rules for the revision content of the innovation scale were inferred using the method of proportion reasoning. Twenty postures were randomly selected for correlation verification.
