Background and Objective: Grip strength is one of the important parameters in hand muscle function that can be negatively affected by vibration. This study aimed to determine the effect of sport intervention on the grip strength of workers exposed to hand-arm vibration.
Materials and Methods: This descriptive-interventional study was conducted on the workers (n=41) of one of the metal industries in Isfahan, Iran. The required data were collected through the completion of demographic questionnaires, measurement of hand-arm vibration acceleration based on ISO 5349, and assessment of grip strength with a Jamar dynamometer. The intervention of hand sports movement was performed for 8 weeks. The gathered data were analyzed in SPSS-21 software.
Results: The grip strength of the workers was significant before and after exposure to vibration (P<0.001). The mean scores of workers' grip strength were obtained at 42.16±3.8 and 39.55±3.97 kg force before working with the vibrating tool and after the end of the work shift and finishing working with the vibrating tool, respectively. The difference between grip strength before and after the intervention of hand sports movements was significant (P<0.001).
Conclusion: The results of this study showed that vibration reduced the grip strength of workers; while performing the intervention of hand sports movements was effective in improving the workers' grip strength. Therefore, sports movements could effectively and efficiently improve the grip strength of workers exposed to vibration.
