ABSTRACT
Background: Construction workers have excessive and repetitive overhead arm movements which places high demands on shoulder muscle strength and endurance. It is important to have good scapular muscle endurance in construction workers to prevent work related musculoskeletal disorders. Studies have shown that pain has negative impact on muscle strength i.e., muscle strength reduces in chronic pain. However, the effect of pain on muscle endurance is not been studied so this study explores the effect of chronic shoulder pain on the scapular muscle endurance.
Aim: To study the effect on scapular muscle endurance in construction workers with chronic shoulder pain.
Methodology: 50 construction workers were included where 25 subjects with chronic shoulder pain (group 1) and 25 without shoulder pain (group 2) were recruited fulfilling the inclusion criteria. Written consent was obtained from each subject. Each participant was interviewed Nordic musculoskeletal questionnaire for non-specific chronic shoulder pain and pain intensity was recorded using Visual analog scale. Both the group subjects were tested for scapular muscle endurance using scapular endurance test; two trails of the test were performed.
Results: The scapular muscle endurance was significantly lower in Group 1 with chronic shoulder pain than in Group 2 without pain (p < 0.05).
Conclusion: Our study assessed the effect of scapular muscle endurance in construction workers with chronic shoulder pain, and our results suggest that the scapular muscle endurance was significantly lower in group having shoulder pain.
