Abstract
BackgroundNo 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.MethodsFifty-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.ResultsBased 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.Conclusion1) 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.
Highlights
No previous studies have investigated the test–retest reliability of tip, key, and palmar pinch force sense in healthy adults
Different types of pinch grips or combinations of these pinch grips with different force levels are frequently used in workplaces
The lower standard error of the measurement (SEM) values and the narrower 95% limits of agreement (LOA) in the absolute error (AE) and constant error (CE) variables obtained for 30 and 50% Maximal voluntary isometric contraction (MVIC) compared with 10%
Summary
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. There are three types of conscious proprioceptive senses: kinesthesia, joint position sense, and force sense [1, 2]. Different types of pinch grips (tip pinch, palmar pinch, key pinch [5,6,7,8,9]) or combinations of these pinch grips with different force levels are frequently used in workplaces. Pinching an object is a complex motor task since a
