Grip strength accounts for hand dominance

At both 6 month and 12 month, none of Jebsen-Taylor test, grip strength, 2-point pinch strength, 3-point pinch strength and key pinch strength showed significant difference between less versus more severe groups, adjusting for age, gender and baseline values of the outcome variables.
