N2 - For motor learning tasks, different feedback methods to the user may impact the efficiency of motor training. Microsoft Kinect has shown great potential as an assistive device for home-based exercise training. This study introduces a Kinect-based skeleton-matching feedback system and compares its training outcomes with those of traditional mirror feedback in order to explore its applicability for use in home-based motor training. Forty healthy adults were randomly divided into an experimental group and a control group, and were instructed to perform a set of continuous shoulder motions using Kinect-based skeleton-matching feedback and traditional mirror feedback respectively. Fisher's z-transformed Pearson's correlation coefficient (rz) and root-mean-square error (RMSE) were used to evaluate angular differences in shoulder movements between the subject's actual motion and a reference motion for each group. Compared to the results under mirror feedback, r values with skeleton-matching feedback were significantly improved for symmetric abduction (SA), asymmetric abduction (ASA), and symmetric flexion/extension (SFE) (P<0.05), and RMSE values were significantly decreased for symmetric flexion/extension (SFE) (P<0.001). Therefore, the Kinect-based skeleton-matching feedback system boasts greater training efficiency for shoulder motor learning and has great potential as an assistive device for home-based rehabilitation exercise training.
