Outcome Measures

Primary Outcomes (1)

  • Presynaptic inhibition level

    Change in Hmax amplitude during vibration

    1 day

Study Arms (1)

Vibrator

EXPERIMENTAL

Local or Whole body vibration was applied at six different frequencies to Healthy control and spastic spinal cord injury. For local vibration, vibration frequencies were 50, 85, 140, 185, 235 and 265 Hz . For whole body vibration, vibration frequencies were 35, 37, 39, 41, 43 and 45 Hz

Device: vibrator
