Increased shoulder abduction (SABD) loading resulted in a significantly decreased accuracy rate in the stroke group. Mean and SE of classification error rate in the stroke group (N = 21) and in the able-bodied group (N = 8). Table, participant’s tested arm was fully supported on a rigid flat surface; SABD25 and SABD50, participant lifted the tested arm with a weight that equaled to 25 and 50% of his/her maximal SABD torque, respectively.
