Table 2.
Results for repetitions, compensation, and kinematic variables presented for each participant and as group mean (SD). Repetitions and compensations are calculated from performance relative to individualized reach and trunk flexion thresholds within VRShape. The average percentage magnitude achieved beyond (reach) or below (compensation) is also presented. Baseline trunk flexion angles are calculated from calibration data.
