• Conditions: Hand Grip Strength; Torque

• Registration Number: NCT06851689
• Lead Sponsor: Cairo University

Brief Summary

The aim is to reduce the incidence of hand grip weakness and shoulder rotation torque decline. this proposed study aims to suggest solutions to prevent occurring injuries

Detailed Description

Teaching is becoming a high-risk job for injuries. In recent years, there has been a growing concern about work-related musculoskeletal disorders (WMSDs) among teachers. These disorders include injuries and pain in muscles, tendons, and nerves. Studies show that teachers are more likely to experience WMSDs than people in other professions, with rates reported to be between 39% and 95%. This is a serious issue that deserves attention after being ignored for a long time.

Potential for Injury Prevention: Physical therapy and occupational health professionals can utilize this correlation to design preventive strategies. For instance, if a significant correlation exists, interventions aimed at improving shoulder torque through specific exercises could also enhance hand grip strength, thereby reducing the risk of musculoskeletal injuries among university teaching staff . Educational and Workplace Ergonomics: Insights from this correlation can inform educational institutions and workplaces about ergonomics and physical fitness programs. Implementing ergonomic practices and wellness programs that target upper body strength could potentially improve overall health outcomes and productivity among university teaching staff . One of the primary issues among university teaching staff is the prevalence of shoulder and upper limb problems. Treatment typically focuses solely on the shoulder and neglects the wrist. Workers in overhead workplaces are in a hazardous position . Ergonomic solutions should be developed to prevent muscle fatigue and decreased grip force.

The aim is to reduce the incidence of hand grip weakness and shoulder rotation torque decline.Given the fact that many injuries are preventable, this proposed study aims to suggest solutions to prevent occurring injuries. Based on the findings, recommendations could potentially decrease shoulder and hand problems and enhance the quality of life for the university teaching staff. Insufficient research has been conducted on the association between hand grip strength and shoulder muscle torque in teaching staff. Therefore, this study aims to pave the way for future research to address this critical issue. There is a gap in the literature about hand grip strength and shoulder rotation torque between university teaching staff so This study will be conducted to investigate the correlation between rotation shoulder torque and hand grip strength between university teaching staff.
