The correlation between the grasping force and the load force. Correlation between the grasping force (F g ) and the load force (F l ) for each phase separated: grasping phase (gPh), transport phase (tPh) and release phase (rPh). The load force is the vertical component of the measured force on the end-effector. The results are shown for subacute, chronic, and control group who had no grasping assistance (dGA).
