Hammer simulation kinematic analyses. Daily average for all twelve subjects during Hammer Task training in a. the length of the path required to complete ten targets. b. time required to hammer each virtual cylinder c. in hand trajectory smoothness quantified as normalized integrated jerk (values are dimensionless, lower scores indicate smoother path with fewer subunits). d. peak finger extension. 3e. hand deviation calculated as the cumulative excursion of the hand position in 3D space from the center of the target starting at the time target is acquired until completion of hammering (lower scores indicate more stability). 3f. Individual subjects start measure (average of first two training days), and end measure (average of last two training days) for all twelve subjects in average hand deviation during hammer task training. Error bars = Standard Error of the Mean.
