This study compares tendon reflex gain, contraction rates, half-relaxation rate, reflex threshold in peak tendon tapping force, and reflex-loop delay between stroke patients and nondisabled controls at different elbow flexion angles. Findings provide insights into hyperactive reflexes post-stroke.

Figure 4. Comparison of (a) tendon reflex gain (Gs), (b) contraction rates (Rc), (c) half relaxation rate (Rhr), (d) reflex threshold in peak tendon tapping force (fth), and (e) reflex-loop delay (td) between patients with stroke and nondisabled controls across three elbow flexion angles. Vertical bars represent standard deviation across subjects. Liu J, Xu D, Ren Y, Zhang LQ.
