Abstract
The purpose of this study was to compare the physical demands associated with three direct-current (DC) right angle power tool tightening strategies. Thirty-six participants (x ̅ = 37.14 years ± 12.03) were assigned to one of two experimental groups: 1) Hard joint (30o, n=18), and, 2) Soft joint (540o, n=18). Within each experimental group, participants performed 36 trials, consisting of 3 tightening strategies, 3 target torques and 4 joint locations, in random order. Data from 3Dlinear sensor handle, motion capture markers, and Borg ratings were analyzed. Repeated measures ANOVA with Tukey’s post hoc test were used to determine statistical significance (p<0.05). Participants operating the TurboTight® fastening strategy experienced the least forces at the hand-handle interface, least joint angle displacements (shoulder & elbow angular displacement) as well as reported the lowest ratings of discomfort and strength.
