Figure 1From: Interaction torque contributes to planar reaching at slow speed Target position. Five small targets (1.0 × 1.5 cm) were placed in front of the shoulder joint of the subject. The distance from the shoulder joint was adjusted to 80% of the upper arm length of the each subject. Target positions required shoulder flexion of 45 deg (T45), 60 deg (T60), 75 deg (T75), 90 deg (T90), and 105 deg (T105).Back to article page
