A Takei T.K.K. 5401 GRIP-D handgrip dynamometer (Takei Scientific Instruments, Niigata, Japan) was used for data collection. Although American Society Hand Therapist (ASHT) recommends using hydraulic type dynamometer (Jamar and its variants), this mechanical type dynamometer (Smedley type) is commonly used in Asia, and its test-retest reliability is known to be excellent.[8 (link)] Measurements were performed with the participants standing up, arm at their side with their elbows fully extended. The participants were asked to squeeze the dynamometer thrice with both hands with a 1 min resting period between each set to overcome fatigue. The mean value of three squeezes was computed.
A Wilcoxon signed-rank test was used to compare variables between baseline and 6 months after CHT. Rex (version 4.0.0; RexSoft Inc., Seoul, Korea) was used for analysis, and a P-value less than 0.05 was considered to be statistically significant.
