Study Details

Brief summary:

The objectives of the study are to evaluate a 4-week mixed training paradigm consisting of explosive strength training and balance perturbation training efficacy on balance control during standing and locomotion, and to understand the mechanisms of neuroplasticity that would improve sensorimotor integration at supraspinal and spinal levels.

Interventions and Outcome Measures

Arms

experimental: Combined explosive strength and specific balance training group

This group will be formed with participants with incomplete spinal cord injury. This group will perform 4 weeks of combined explosive strength and specific balance training.

no intervention: Spinal cord injury control group

This group will be formed with participants with incomplete spinal cord injury. They will perform all the evaluation before and after a 4-week period of rest (no training).

no intervention: Healthy control group

Healthy participants will be recruited based on the age and sex of the participants with incomplete spinal cord injury to realize clinical and neurophysiological cortical evaluations.

Interventions

Combined explosive strength and specific balance training group

Training will consist to perform one hour of combined ankle explosive strength training and specific balance training using randomized perturbations.

Explosive strength training: Participants will perform only 2 sets of 3 min (12 contractions for each set) for both lower limbs and both ankle plantar- and dorsiflexion movements.

Balance specific training: Participants will be standing, secured by an adjusted harness, which do not support the weight but is strictly there to prevent a fall. They will have online visual feedback of their CoP via an avatar on the screen in front of them. Each training session will consist of 10 sequences of 3 min, including the 5 different conditions:

  • Forward tilt of base of support;
  • Backward tilt of base of support;
  • Translation forward;
  • Translation backward;
  • Without moving their feet, participants will have to move their avatar to reach different targets placed around them on the screen, at different distance from the center.

Primary outcome measure

  • Change in muscles EMG responses following balance perturbation [ Time Frame: Pre-intervention, immediately after and one-month after intervention ]
  • Change in center of pressure displacement following balance perturbation using a force platform [ Time Frame: Pre-intervention, immediately after and one-month after intervention ]
  • Change in ankle muscle strength using force transducer [ Time Frame: Pre-intervention, immediately after and one-month after intervention ]
