Functional Electrical Stimulation During Cycling in People With Spinal Cord Injury — iCycle  

Spinal Cord Injuries Clinical Trial

Official title:
The Effects of FES Cycling Combined With Virtual Reality Racing on Lower Limb Voluntary Function After Incomplete SCI: A Pilot Study.

Clinical Trial Summary

Neuroscience research that has identified potential for recovery (neuroplasticity) following incomplete SCI has changed clinical practice away from compensation strategies towards optimizing recovery. Important factors include: repetitive exercise, Functional Electrical Stimulation (FES) and appropriate feedback. The iCycle combines repetitive exercise with FES and provides feedback on performance in a virtual cycle race. Unlike previous devices, performance in the race is determined only by voluntary effort (i.e. not torque generated by FES plus voluntary effort). In this study with incomplete SCI participants we will test the iCycle with six inpatients to refine the protocol and make technical improvements. We will then conduct an ABA pilot study (n=10) in which a 3G-connected iCycle is used in people's own homes. We will compare usual care (A) with iCycle exercise (B). Changes in neural connectivity (TMS evoked EMG potentials), muscle strength and walking will be measured as well qualitative analysis of users' views.

Clinical Trial Description

Background: Functional Electrical Stimulation (FES) cycling can benefit health and may lead to neuroplastic changes following incomplete spinal cord injury (SCI). Our hypothesis is that greater neuroplastic effects occur when electrical stimulation of peripheral nerves is combined with voluntary drive. In this pilot study, we will investigate the effects of a one-month training programme using a novel device, the iCycle, in which voluntary effort (cortical drive) is encouraged by virtual reality biofeedback during FES cycling. Methods: Eleven participants (C1-T12) with incomplete SCI (5 sub-acute; 6 chronic) will be recruited and undergo 12-sessions of iCycle training. Function will be assessed before and after training using the bilateral ISNC-SCI motor score neurological (motor) function, Oxford power grading, Modified Ashworth Score, Spinal Cord Independence Measure, the Walking Index for Spinal Cord Injury and 10m-walk test. Power output will be measured during training. ;
