“…This finding is in agreement with previous reports that the strength of the dominant hand is stronger than of that of the non-dominant hand. 18,19 To our knowledge, this study is one of the first attempts to characterize various pinch strength exertions among the children and young adult population in the northwest of Iran. However, care should be given when applying the findings of this study as the participants in this study may not be the representative of the Iranian population, and thus the findings may not be generalizable to other ethnic groups in Iran.…”

Article type: Original ArticleBackground: Data on the physical strength capabilities are essential for designing safe and usable products and are useful in a wide range of clinical settings especially during treatment of disease affecting the function of the hand. The purpose of this study was to determine peak lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions in a healthy Iranian children and young adult population. Methods: The study was conducted among 511 participants (242 males and 269 females) aged 7-30 years. Measurements were carried out with both dominant and non-dominant hands in standard sitting posture using a B&L pinch gauge. Two repetitions of each strength measurement were recorded for each condition and the average value of the two trials was used in the subsequent analysis. Results:The results showed significant differences in the pinch strength data in terms of the age, gender and hand dominance. The lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions by females were 68.4%, 68.8%, 78.8% and 81.8% of those exerted by males, respectively. Strength exertions with the non-dominant hand were 6.4%, 5.2%, 6.6% and 5.1% lower than strength exertions of the dominant hand for the lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions, respectively. Conclusion: These findings can be used to fill the gaps in strength data for Iranian population.
