Table 2.
Root mean square (RMS) differences between the simulated joint kinematics and handrim forces and corresponding mean experimental value for each biofeedback condition. For comparison, one standard deviation (SD) of the experimental data is provided (in parentheses) to indicate inter-subject variability.
