Dw. Repperger et al., PERFORMANCE STUDY INVOLVING A FORCE-REFLECTING JOYSTICK FOR SPASTIC INDIVIDUALS PERFORMING 2 TYPES OF TRACKING TASKS, Perceptual and motor skills, 81(2), 1995, pp. 561-562
10 upper-extremity spastic subjects and 10 normal subjects were studie
d with a force-reflecting joystick in the performance of a continuous
time-tracking task as well as an acquisition task termed, ''Fitts' Law
.'' Certain force-reflection paradigms, in a spatial sense, allowed th
e spastic subjects to obtain performance proficiency near levels of th
e normal subjects as measured by a capacity metric.
