    Abstract:
    BACKGROUND: No previous studies have investigated the test-retest reliability of tip, key, and palmar pinch force sense in healthy adults. The present study explores the test-retest reliability of tip, key, and palmar pinch force sense for different force levels in healthy adults during an ipsilateral force reproduction task. METHODS: Fifty-six healthy subjects were instructed to produce varying levels of reference forces (10, 30, and 50% maximal voluntary isometric contraction (MVIC)) using three types of pinches (tip pinch, palmar pinch, and key pinch) and to reproduce these forces using the same hand. The subjects were tested twice by the same experienced testers, 1 week apart. RESULTS: Based on the high values of the intraclass correlation coefficient (ICC), the tip pinch (0.783-0.895) and palmar pinch (0.752-0.903) force sense tests demonstrated good reliability for all the variables. The ICCs for the key pinch (0.712-0.881) indicated fair to good relative test-retest reliability. CONCLUSION: 1) This study demonstrates that high test-retest reliability of tip, key, and palmar pinch force sense in healthy adults can be achieved using standardized positioning and the proposed approach. 2) According to the reliability measurements, 30 and 50% maximal voluntary isometric contraction (MVIC) are the most reliable pinch force sense levels.
