Purpose. Loss of static muscular strength is the most common work-related problem among handicraft workers involved in hand-intensive jobs. A cross-sectional comparative assessment was carried out to determine the muscular strength among workers involved in the manufacturing of three different crafts: weaving, hand block printing and imitation jewelry. Methods. 120 female operatives were selected, and digital grip dynamometers were used to measure their maximum hand grip and pinch strength. Results. Static muscular strength varies significantly among the different occupational groups of workers. The difference in grip strength in the right and left hands shows that exposure to hand tools for a prolonged period plays a vital role in muscle strength. These findings indicate that static muscular strength varies significantly due to repetitive use of hand tools. The observed values of muscle strength in the dominant hand were significantly lower in jewelry workers while block printing workers had the highest strength. Conclusion. The decrement in pinch grip strength was evident due to long-cycle repetitive pinching movements of the distal phalanx during hand knotting and pearl drilling. This study proposes the need for ergonomically designed hand tool interventions that may reduce the accumulation of loss in static muscle strength. © 2018 Central Institute for Labour Protection–National Research Institute (CIOP-PIB).
