Assessment of Hyperactive Reflexes in Patients with Spinal Cord Injury

Figure 6

Comparison of tendon tapping results between two SCI individuals with spastic hypertonia. Subject D in the left olumn had an extremely strong reflex-mediated torque response but it damped out quickly, dropped to zero at 350 milliseconds (red dot). Subject A in right column, in contrast, had a less strong reflex-mediated torque response but it lasted much longer, dropped to zero at 600 milliseconds (red dot), indicating stronger tonic reflex response.
