Functional Electrical Stimulation Therapy After Stroke
- Conditions
- Stroke
- Interventions
- Device: NeuroLife FES Sleeve / NeuroLife EMG-FES Sleeve
- Registration Number
- NCT06207240
- Lead Sponsor
- Battelle Memorial Institute
- Brief Summary
The goal of this feasibility study is to test the feasibility of providing task-oriented, intention-driven functional electrical stimulation (FES) using the novel NeuroLife FES Sleeve and NeuroLife electromyography (EMG) and FES Sleeve devices in chronic stroke survivors. The main questions it aims to answer are:
* Can these devices be used to administer task-oriented therapy with assistive stimulation at similar doses to current standards of care?
* How does therapy using these devices impact the upper limb function in a few chronic stroke survivors?
Participants will receive assistive electrical stimulation synchronized to their movement intention while practicing functional tasks with everyday objects over the course of 8 weeks.
- Detailed Description
Battelle has developed the NeuroLife FES Sleeve and NeuroLife EMG-FES Sleeve devices, wearable sleeves that deliver non-invasive functional electrical stimulation (FES) paired with user intention. Participants in this study will use these devices while practicing functional tasks for about one hour at each session. FES will be applied through the forearm sleeve devices to assist with hand movements and grasps required by functional tasks simulating everyday activities such as turning a key or picking up a phone.
Sessions will be scheduled three days per week for 8 weeks total. Participants will complete clinical assessments at the beginning, midpoint and end of intervention as well as at follow-up sessions 2- and 10-weeks after the end of intervention to track upper limb function and impairment. Each session will last 1.5-2 hours, and participants will be compensated for their time.

Group Intervention Description FES Therapy NeuroLife FES Sleeve / NeuroLife EMG-FES Sleeve Intention-driven assistive functional electrical stimulation provided during approximately 1 hour of task-oriented therapy. Sessions will be scheduled 3 days per week for 8 weeks.
- Primary Outcome Measures
Name Time Method Action Research Arm Test (ARAT) Week 0 (Baseline), Week 4 (Mid-Intervention), Week 8 (Post-Intervention), Week 10 (2-Week Follow Up), Week 18 (10-Week Follow Up) The Action Research Arm Test (ARAT) will be used to track functional changes from the pre-intervention baseline. The ARAT is a common measure of upper extremity function after stroke ranging from 0 (maximal impairment) to 57 (no impairment).
Therapy Dose Week 0-18 (during the intervention and follow-up periods) Therapy Dose was used to estimate the feasibility of the therapy. Therapy Dose will be computed as the average amount of time at each session the subject was engaged in intention-driven, task-oriented functional electrical stimulation therapy, excluding the time needed to set up the system.
- Secondary Outcome Measures
Name Time Method Box and Block Test (BBT) Week 0 (Baseline), Week 4 (Mid-Intervention), Week 8 (Post-Intervention), Week 10 (2-Week Follow Up), Week 18 (10-Week Follow Up) The Box and Block Test (BBT) will be used to track dexterity changes from the pre-intervention baseline. The BBT is a common measure of unilateral gross manual dexterity after stroke quantified by the number of blocks transferred between boxes within 60 seconds.
Motor Activity Log Week 0-8 (during the intervention period) The Motor Activity Log (MAL) will be used to track participants' use of their impaired arm throughout the study. The MAL is widely used to assess how stroke survivors use their more-impaired arm outside the laboratory through semi-structured interviews capturing the amount of use and quality of movement using their arm.
Fugl-Meyer Assessment-Upper Extremity (UEFM) Week 0 (Baseline), Week 4 (Mid-Intervention), Week 8 (Post-Intervention), Week 10 (2-Week Follow Up), Week 18 (10-Week Follow Up) The Fugl-Meyer Assessment-Upper Extremity (UEFM) subscore will be used to track impairment changes from the pre-intervention baseline. The UEFM is a common measure of upper extremity impairment after stroke ranging from 0 (maximal impairment) to 66 (no impairment).
Nine-Hole Peg Test (NHPT) Week 0 (Baseline), Week 4 (Mid-Intervention), Week 8 (Post-Intervention), Week 10 (2-Week Follow Up), Week 18 (10-Week Follow Up) The Nine-Hole Peg Test (NHPT) will be used to track dexterity changes from the pre-intervention baseline. The NHPT is a common measure of unilateral manual dexterity after stroke quantified by the time taken to transfer nine pegs from holes to a dish.
