Introduction: Handicrafts seems to be one of the high‑risk jobs regarding work‑related
musculoskeletal disorders (WMSDs) which necessitate the implementation of different
corrective intervention like regular physical activities. This study aimed to investigate the
impact of physical activity on WMSDs among craftsmen. Methods: This cross‑sectional study
was an analytical – descriptive study carried out on 100 craftsmen working in Isfahan, Iran,
in 2013. The sampling method was census, and all workshops involved with this job were
included. Information on demographic parameters and physical activity was collected by
demographic forms. The data related to worker’s musculoskeletal discomforts were conducted
using Cornell Musculoskeletal Discomfort Questionnaire. The data were analyzed using
statistical tests including independent t‑test, Chi‑square, and ANOVA. The statistical analysis
was performed using SPSS 18. Results: The highest percentages of complaints related to
severe musculoskeletal discomfort were reported in right shoulder (%36), right wrist (%26),
neck (%25), and upper right arm (%24), respectively. A significant relationship was observed
between physical activity and musculoskeletal discomforts of left wrist (P = 0.012), lower
back (P = 0.016), and neck (P = 0.006). Discussion and Conclusion: Based on the study
results, it can be inferred that regular but not too heavy physical activity can have a positive
impact on decreasing the musculoskeletal discomforts.
