Study summary

Electrical spinal stimulation combined with activity-based rehabilitation (ABR) can improve motor and autonomic function in individuals suffering from varying degrees of paralysis. Spinal stimulation studies have included invasive implanted devices and non-invasive transcutaneous systems using different combinations of stimulation current, waveform, amplitude, duration and spinal levels targeted. Invasive and non-invasive systems have been demonstrated to permit individuals with chronic spinal cord injury (SCI), previously considered to have complete injuries on the International Standards for the Neurological Classification of Spinal Cord Injuries (ISNCSCI) scale (Classification A), to regain some degree of voluntary and autonomic function during periods of stimulation. The aim of this study is to evaluate the effects of a novel non-invasive transcutaneous electrical spinal cord stimulation system (tSCS) combined with activity-based rehabilitation in patients who have paralysis of their legs and/or arms. We will examine participants for any changes in sensory, motor or autonomic function. We will use a transcutaneous spinal cord stimulator that has been designed to deliver safe and tolerable bursts of high frequency pulsed current that minimise the capacitance efforts of the skin surface and maximise conductance of a second waveform using low frequency current to target neural structures. We aim to investigate this form of neuromodulation with a small group of individuals with chronic spinal cord injury. Our goal is to observe and describe any short term or lasting changes in function that can safely and comfortably be derived from this combination of spinal stimulation and activity-based rehabilitation. If this therapy can cause lasting improvements in sensory, motor, respiratory or autonomic function, then this may lead to a greater degree of functional independence for these individuals.

What researchers measure

Primary outcomes

    Sensory and motor scores. Sensory scale 0-224, motor scale 0-100 with higher scores relating to increased sensation and motor power

    Time frame: 1 year

  2. Spinal Cord Independence Measure (SCIM)

    Functional independence tool for spinal cord injury. Scale of 0-100, with higher scores meaning increased function

    Time frame: 1 year

  3. Berg Balance Score (where applicable)

    Measure of standing balance. Scale of 0-56, with higher values meaning increased standing balance and reduced risk of falls

    Time frame: 1 year

  4. NeuroRecovery Scale (NRS)
