| Sumario: | BACKGROUND: Grip and pinch strength measurement is important for objective evaluation of the function of the upper extremities in upper limbs injuries treatment and alsofor ergonomists as a way of optimizing the requirements of hand tool design. OBJECTIVE: The present study was conducted to investigate the correlation of anthropometric and demographic factors with hand strength as well as to develop regression models for grip and three types of pinch strengths including Tip, Key and Palmar in Iranian adult population. METHODS: The study population consisted of 1008 Iranian adults aged 20 to 107 years. Participants were selected using a stratified random sampling method from crowded places of the cities with the highest number of Persian ethnic group. Strength measurements were undertaken according to recommendations by the American Society of Hand Therapists (ASHT). RESULTS: This study found a positive and significant correlation between all measured strengths and anthropometric factors. The regression equations of grip and pinch strengths were developed for dominant and non-dominant hands. CONCLUSION: The results of this study provided more information about correlated factors of grip and pinch strengths. The regression equations developed in this research are applicable to clinical treatment and ergonomics programs. |
