Plain English summary of protocol

Background and study aims
Hand function is essential for daily living activities. People with spinal cord injury (SCI) can suffer from impaired hand functions. Conventional hand therapy is usually offered at the sub-acute stage of SCI but patients still experience significantly impaired hand function which affects their daily living activities and reduces their quality of life. A system has been developed that uses the electrical signal of the muscles to control functional electrical stimulation of the same muscles. The aim of this study is to determine the best parameters and confirm that people with SCI can adequately use the system both as a rehabilitative and assistive device.

Who can participate?
Patients aged 18–76 with high level SCI that affects their hand function

What does the study involve?
Each participant receives functional electrical stimulation to open and close the hand, controlled by the electrical signals of their muscles. There is a total of three sessions with each session lasting for a maximum of 2 hours.

What are the possible benefits and risks of participating?
There are no known direct benefits to participants but the result will help in further research in the area. There is no known risk as devices are certified.

Where is the study run from?
National Spinal Injuries Centre (NSIC), Stoke Mandeville Hospital, Buckinghamshire Healthcare NHS Trust (UK)

When is the study starting and how long is it expected to run for?
Buckinghamshire Healthcare NHS Trust (UK)

Scientific titleFeasibility of two-channel proportional Electromyogram Controlled Functional Electrical Stimulation (EMG-FES) for augmentation of finger and wrist flexion and extension for application in active neurorehabilitation in spinal cord injury
Study acronymActive FES
Study objectivesThere is evidence that active participation is important in movement rehabilitation. One of the methods of involving active participation during rehabilitation is to control rehabilitation system with voluntary effort. For this purpose, Electromyogram (EMG) has been investigated to trigger the onset or proportionally control the intensity of functional electrical stimulation (FES). The proportional control method is very attractive because it gives a more natural control but it is more difficult to implement because of the issues associated with recording EMG simultaneously with the application of FES. Recent developments have demonstrated potentials of single channel proportional EMG controlled FES as an orthotic and rehabilitation system that can argument either tenodesis, hand flexion or extension. Here the aim is to further research and test the feasibility of a two-channel proportional EMG controlled FES system that can augment both hand and wrist flexion and extension in addition to tenodesis grasp and release

Health condition(s) or problem(s) studiedSpinal cord Injury
InterventionEach participant will receive functional electrical stimulation (FES) to open and close the hand. The FES will be controlled by the person's residual electromyogram. There will be a total of three sessions with each session lasting for a maximum of 2 hours.

Primary outcome measureThe following tests will be measured only once for each condition in the study:
1. Hand function, measured using Toronto rehabilitation institute hand function test (TRI-HFT)
2. Hand function, measured using trapezoidal shape tracing
Secondary outcome measuresThe following tests will be measured only once for each condition in the study:
1. Physical well-being, assessed using the spinal cord independence measure (SCIM)
2. Spasticity muscle hypertonia levels, assessed using the Modified Ashworth Scale (MAS) test
3. Device usability and usefulness, assessed using a series of questionnaires including the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST)
4. Functional impairment, assessed using the International Neurological Standards for Spinal Cord Injury (ASIA impairment scale)
