Abstract: Objective. This study tested the between-day repeatability and effect of wrist positioning on grip strength measurement. Method. Thirty healthy men 20 years to 69 years of age were tested twice, 1 week apart, in six wrist positions. Results. The findings showed good repeatability for grip strength, with the intraclass correlation coefficient [ICC(1, 3)] ranging from .9043 to .9663. Significant differences were found in grip strength among the six positions (p < .001), with grip strength measured at 15° or 30° of wrist extension (EXT) and 0° ulnar deviation (UD) significantly greater than that of O° UD and 0° EXT or 15° UD with or without EXT. This finding suggests the clinical importance of standardizing the testing position for grip strength measurement. Conclusion. The high repeatability of the tests supports the use of the grip strength measurement to evaluate treatment progress.
