Effect of Structured Exercise-Based Intervention on Upper Quadrant Dysfunction among Fish Processing Workers with...

Area of Science:

• Occupational Health
• Rehabilitation Medicine
• Ergonomics

Background:

• Musculoskeletal disorders (MSDs) are a significant cause of morbidity, particularly affecting the upper quadrant in industrial environments.
• The impact of workplace exercise programs on worker well-being remains debated.
• This study investigated the effect of a structured exercise intervention on upper quadrant dysfunction in fish processing workers with work-related MSDs.

Purpose of the Study:

• To evaluate the effectiveness of a structured exercise-based intervention (SEBI) on upper quadrant dysfunction.
• To assess the impact of SEBI on the quality of life (QoL) of fish processing workers.
• To determine if SEBI can mitigate work-related MSDs in this population.

Main Methods:

• A cluster-randomized controlled trial involving 184 fish processing workers.
• The intervention group (n=91) underwent a 3-month tailored SEBI program including stretching, strengthening, and active exercises.
• The control group (n=93) maintained routine activities. Outcome measures included Neck Disability Index (NDI), Disabilities of Arm, Shoulder, and Hand (DASH), Visual Analog Scale (VAS), and Short Form-36 (SF-36).

Main Results:

• Statistically significant improvements were observed in NDI, DASH, and VAS scores for the intervention group compared to the control group (P < 0.0001).
• The SEBI program led to significant differences in QoL, particularly in physical and psychological health sub-domains.
• Overall perception of upper quadrant dysfunction was markedly reduced by the intervention.

Conclusions:

• Structured exercise-based intervention (SEBI) is effective in improving upper quadrant function and QoL among fish processing workers.
• SEBI demonstrates a positive impact on general health measures, including NDI, DASH, VAS, and SF-36.
• Implementing SEBI in fish processing industries is recommended to address upper quadrant dysfunction and enhance worker well-being.
