Difficulty with walking is one of the most common effects of stroke. Even after rehabilitation, a majority of stroke survivors have decreased speed, endurance, confidence, and quality of walking. Walking deficits can cause risks of falls, slow walking speed, increased effort of walking, and difficulties with activities of daily living. Restoration of walking ability can improve quality of life, and is perceived as a major goal of rehabilitation by stroke survivors. There has therefore been renewed interest in research toward developing novel gait rehabilitation treatments and improving existing treatments. FastFES is one such intervention, which improves walking post-stroke using a combination of fast treadmill training and functional electrical stimulation (FES).
Ongoing research at the University of Delaware (R01NR010786) shows that a 12-week FastFES gait rehabilitation program improves walking function, activity, and community participation in stroke survivors.
In order to facilitate implementation of the FastFES gait rehabilitation program in the clinical setting, there is a need to transition from the currently used stimulation system to a more portable stimulation system. The Study Device under evaluation is a pre-commercial prototype (developed by customKYnetics, Inc.) of a clinically viable portable electrical stimulation system that can deliver FES during gait using similar timing and parameters as are being used during FastFES gait rehabilitation training in the ongoing research.
The main goal of the efficacy study is to demonstrate clinical efficacy of the customKYnetics FastFES prototype system for improving the gait of individuals with paresis secondary to stroke. Fifteen (15) post-stroke subjects who meet the inclusion/exclusion criteria will be recruited for participation in this prospective, non-randomized, non-blinded cohort interventional study.
Training (intervention sessions) will be conducted 2-3 times per week for approximately 12 weeks for a total of 36 total sessions. Functional Electrical Stimulation (FES) to the ankle plantarflexor and dorsiflexor muscle groups will be delivered during the gait cycle using a variable frequency train (VFT) stimulation pattern. Stimulation will be coordinated to the gait cycle using data from a shoe-worn inertial sensor and proprietary real-time signal processing algorithm. Stimulation will be turned on and off in 1-minute increments during the training bouts to promote motor learning. The treadmill will be set to the patient's fastest comfortable walking speed. Each intervention session will conclude with a single overground walking session without FES.
Outcome measures assessments will be performed at the following milestones: pre-intervention, after 18 training sessions, post-intervention, and at a 12-week follow-up. This Small Business Innovation Research (SBIR) funded efficacy study will mimic the study protocol used in the R01-funded randomized controlled trial (RCT). Outcomes from the SBIR cohort will be compared to non-concurrent (e.g., historical) control groups drawn from the R01-funded RCT. The main outcomes of this study will be: 1) validation of customKYnetics' prototype system for improving gait deficits; and 2) comparison of the outcome measures of patients who trained with the customKYnetics system with those from the 'fast treadmill walking with FES' arm intervention cohort in the RCT.

Single Group Study - see Intervention Description
Fast treadmill walking supplemented with FES to ankle plantarflexor and dorsiflexor muscles, using a VFT stimulation pattern. 12 weeks of 2-3x/week. Stimulation delivered using the customKYnetics study device.
- Change from baseline in "6-minute Walk Test (6MWT) for Distance" at 12 weeks [ Time Frame: weeks 0 and 12 ]Distance (meters) walked during the 6-minute Walk Test, a standard clinical assessment of gait will be assessed at 0 and 12 weeks. Test will be performed overground without FES. Change from baseline at 12 weeks will be computed.
