Trial 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.

About this study

Official title: Central and Peripheral Neuroplasticity in Cervical Spinal Cord Injury Following Intensive Upper Limb Motor Training

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.

Read the detailed description

Background of the study:

Paralysis or paralysis is the most common effect of spinal cord injury (SCI) on individuals. Paralysis affects the ability to walk, perform self-care, live independently and participate in work and leisure activities. In individuals with cervical spinal cord injury, arm and hand function is very important. The most promising and easily implemented intervention that could promote neurological recovery and make a lasting difference in the lives of people with spinal cord injuries is early and intensive motor training aimed at recovery below the injury level. This intervention takes advantage of the early plasticity of the nervous system. By maximizing muscle activation in the first few weeks after injury, we can target the nervous system's unique capacity for neural plasticity where changes can occur in central and peripheral motor systems.

Objective of the study:

This project aims to investigate peripheral and central neuroplasticity following an early (<13 weeks after injury) and intensive (8 weeks of 6 hours of additional therapy) upper extremity motor training program (EIUMT) aimed at recovery below the lesion level. This project has 4 objectives: to investigate 1) central neural plasticity (identify changes in cortical neuroplasticity and corticospinal excitability; 2) peripheral neural plasticity (identify change in axonal excitability and number of motor units); 3) clinical motor recovery of the upper limbs and 4) relationships between dose dimensions of motor intervention and clinical and neurophysiological outcome measures after EIUMT. Advanced neurophysiological measurements and clinical measurements will be taken before and after EIUMT and at 6-month follow-up.

Study design:

a multicenter pragmatic randomised controlled study in 2 countries

Study population:

44 persons with cervical spinal cord injury (22 participants in the control and intervention groups) Inclusion criteria: Individuals are eligible to participate if they have suffered a traumatic or non-traumatic cervical spinal cord injury within the previous 13 weeks, have AIS (ASIA Impairment Scale) A lesion with motor function more than three levels below motor level (on one or both sides) or have AIS C or AIS D lesion (as defined by the International Standards for the Neurological Classification of spinal cord injury), are older than 16 years of age, have received permission to begin rehabilitation and are likely to remain an inpatient for the next 8 weeks.

Exclusion criteria: Participants will be excluded if they have a significant medical or physical condition or psychiatric illness that could prevent the person from participating in the study or would place the person at unacceptable risk if they were to participate.

Intervention:

The intervention group receives 6 hours of motor training each week. This involves active and targeted motor training of all affected muscles below the injury level in the context of functional activities.

The control group receives only standard rehabilitation and care.

Primary study parameters/outcome of the study (Baseline vs 8 weeks after randomisation):

Central plasticity via: Single pulse TMS (transcranial magnetic stimulation) (Resting Motor Threshold) Peripheral plasticity via: Peripheral nerve assessment (Compound muscle action potential (CMAP)) Functional recovery via: Grades redefined assessment of strength, sensibility and Prehension (GRASSP)

Secondary study parameters/outcome of the study:

Clinical Measures: Upper Extremity Motor Score, Spinal Cord Independence Measure (SClM-selfcare); Van Lieshout Test (VLT); Hand-Held Dynamometry; accelerometry (session density: active therapy time/session length); perceived difficulty and exertion) Central plasticity: Single Pulse TMS: Stimulus-Response Function, Cortical mapping, Paired pulse TMS: SICI (short interval intracortical inhibition); LICI (long interval intracortical inhibition) Peripheral plasticity: NET (Nerve excitability testing) and MScanFit MUNE.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • experimental group: intensive motor trainingOther

    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.
