Transcranial Magnetic Stimulation (TMS) for Upper Limb Dysfunction in Spinal Cord Injury: a Feasibility Study

Not Applicable
Completed
Conditions
Spinal Cord Injuries
Interventions
Device: Transcranial Magnetic Stimulation using iTBS Paradigm
Registration Number
NCT02914418
Lead Sponsor
Sheffield Teaching Hospitals NHS Foundation Trust
Brief Summary

This study will investigate how repetitive transcranial magnetic stimulation (TMS) using intermittent theta-burst stimulation (iTBS) paradigm affects sensorimotor dysfunction such as pain, spasticity, motor weakness and sensory loss. TMS is technique which allows non-invasive stimulation of the cortex, and can modulate activity of neurons. The purpose of this study will be to assess the feasibility of using TMS with iTBS paradigm to treat sensorimotor dysfunction in people with incomplete spinal cord injury affecting the upper limbs.

GroupInterventionDescription
Active iTBSTranscranial Magnetic Stimulation using iTBS ParadigmiTBS will be delivered using the 50Hz, 600 pulses protocol for 10 sessions over a period of two weeks. The hand representation of the primary motor cortex will targeted using a circular coil held over the vertex of skull. Intensity will be set to 80% of Resting Motor Threshold (RMT), which will be determined visually by the lowest percentage of stimulator output which can cause upper limb motor twitch in at least 5 out of 10 attempts.
Sham iTBSTranscranial Magnetic Stimulation using iTBS ParadigmSham iTBS will be delivered using the 50Hz, 600 pulses protocol for 10 sessions over a period of two weeks. Intensity will be set at 80% RMT. Circular coil will be held over vertex of skull but angled away to ensure no neural stimulation.

Secondary Outcome Measures
NameTimeMethod
Spinal Cord Independence Measure (SCIM) - Version 3Baseline and 2 weeks

scale developed to address the ability of SCI patients to perform basic activities of daily living independently.

Range of Motion (RoM)Baseline and 2 weeks

Active RoM of wrist extension, flexion, elbow extension and flexion of both of both upper limbs will be measured using a goniometer.

Leeds Arm Spasticity Impact Scale (LASIS)Baseline and 2 weeks

Questionnaire assessing impact of spasticity on a person.

Visual Analogue Scale (Spasticity) (VAS-S)Baseline and 2 weeks

A 100mm line with two statements at each end (No spasticity, worst spasticity). The patient will mark on the line their own perception of how bad they feel their spasticity is.

American Spinal Injuries Association Impairment Scale (AIS) (Inc. grading, upper extremity motor score, lower extremity motor score, light touch and pin prick scores)Baseline and 2 weeks

A clinical assessment of sensory dermatomes and key muscle groups of upper and lower limbs.

Modified Ashworth Scale (MAS)Baseline and 2 weeks

MAS is a clinical assessment of spasticity. Spasticity of wrist extensors, flexors, elbow extensors and flexors of both upper limbs will be assessed.

Visual Analogue Scale (Pain) - (VAS-P)Baseline and 2 weeks

A 100mm line with two statements at each end (no pain, worst pain). The patient will mark on the line their own perception of how bad they feel their pain is.
