Sensorimotor Integration Underlying Balance Control in Individuals With Incomplete Spinal Cord Injury
Sensorimotor Integration Underlying Balance Control in Individuals With Incomplete Spinal Cord Injury: Assessing Neural Changes After the Injury and Promoting Recovery Through Specific Training
調査の概要
詳細な説明
After obtaining their consent, participants will undertake evaluations at different times:
- Assessment 1 week prior to training
- Training over 4 weeks (nature of the training depends on the group)
- Assessment 1 week after training
- Assessment 1 month after training (follow-up)
Each assessment will be divided in 2 sessions and data will be collected over 2 days, at one session per day. Days can be consecutive or non-consecutive but will be within a given week. The assessment consists of:
- Session 1 (S1; duration: 3h) will include presentation of the Study and obtainment of consent, clinical tests, galvanic vestibular stimulation testing, postural reactions and gait assessment.
- Session 2 (S2; duration: 3h) will include muscle strength, short-afference inhibition, paired pulse and trans cranial magnetic stimulation conditioning of H reflex.
After the initial assessment, iSCI participants will be separated in 2 groups and will receive combination of explosive strength and balance training or no intervention. The training will span over 12 sessions (3 times per week for 4 weeks) and each training session will last approximately 1h (including effective training and installation periods).

実験的: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.
|
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:
|
介入なし: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).
|
|
介入なし: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.
