Neural Plasticity and Motor Recovery After Upper Extremity Motor Training in People With c-SCI

Summary

After spinal cord injury (SCI), there is a disruption in neural circuits resulting in paralysis. There is not yet a cure for paralysis. In persons with Cervical SCI (pwC-SCI) recovery of arm-hand function is very important as it has a significant impact on the patients' level of independence and quality of life. Recovery is assumed to involve alterations in both central and peripheral motor systems. Motor training at an intensive dosage potentially provides a powerful stimulus for neurological recovery. This project exploits the peripheral and central neuroplastic effect of an early (\<13 weeks after injury) and intensive (8 weeks of 6 hours in addition to usual care) upper limb motor training program (EIUMT) directed at recovery below the level of the injury in pwC-SCI within an international multi-center randomized controlled trial including 44 pwC-SCI. It has 4 objectives: to investigate 1)central neural plasticity by identifying alterations in cortical neuroplasticity and corticospinal excitability; 2)peripheral neural plasticity by identifying alterations in axonal excitability and number of motor units; 3)behavioral motor recovery of upper limb and 4)relationships between dose dimensions of motor intervention and behavioral and neurophysiological outcome measures after EIUMT. Cutting-edge neurophysiological measures are used to provide insight in the mechanism of neuroplasticity after EIUMT and will be taken before and after EIUMT and at 6 months follow-up.

Conditions

• Spinal Cord Injuries

Interventions

OTHER

experimental group: intensive motor training

Intervention group: receive an extra 6 hours of motor training each week (distributed over the week) for 8 weeks. It will involve active and targeted motor training of all affected muscles of the upper limb below the level of the injury within the context of practice of functional activities. Interventions will be goal directed and individualized to the needs of each participant with a focus on training that addresses each person's specific motor problem, promoting motor learning as well as stimulating neural plasticity. All patients will continue to receive usual physiotherapy and usual rehabilitation.
