Muscle Synergy and Musculoskeletal Model-Based Continuous Multi-Dimensional Estimation of Wrist and Hand Motions
Figure 8
Trial-based wrist joint movement estimation performance changes in the synergy-based linear regression model (SLRM) and musculoskeletal model (MSM) in terms of the Pearson correlation coefficient (r) and normalized root-mean-square error (nRMSE). (a) SLRM and MSM had no statistically significant difference in wrist motion with grip, while wrist motion average had a statistically significant difference between the models (, Student’s t-test). (b) nRMSE between SLRM and MSM had a statistically significant difference in every trial.
