  1. The continuous circle tracking tasks are repeated under white noise perturbation, no force and spring assistance force field. The results are grouped by functional levels and force settings. Note: PTT: percentage time in target, RMSE: root mean square error, SM: Speed_Mean; SS: Speed_StdDev, †: Differences significant from another group (p < 0.05). ‡: Differences significant from another two groups (p < 0.05).
