NCT07785700

Brief Summary

This assessor-blinded, randomized, parallel-group feasibility trial will evaluate the feasibility and preliminary effectiveness of a home-based Functional Electrical Stimulation (FES) system for lower-limb rehabilitation in adults recovering from stroke. The study will be conducted at two sites within the INSTRUCT Network in India. Adults aged 18 years or older who are 1 month to 1 year post-stroke and have mild to moderate lower-limb weakness will be eligible to participate. A total of 70 participants will be randomly allocated in a 1:1 ratio to either a home-based FES intervention group or a control group receiving standard rehabilitation. Participants in the FES group will receive training on safe and independent use of the FES device before commencing home treatment. FES will be delivered to selected lower-limb muscles, including the quadriceps, tibialis anterior, and hamstrings, for 30 minutes per session, 5 sessions per week, for 12 weeks. The intervention will be supported by a smartphone-based telerehabilitation platform that will provide remote clinician support, training, adherence monitoring, and troubleshooting. The FES system is being developed with IoT-enabled monitoring and ECG-based heart-rate safety monitoring to facilitate safe home use. Participants in the control group will receive standard outpatient care and home-based rehabilitation without FES. Both groups will receive equivalent remote clinician contact and education. The primary purpose of the study is to determine the feasibility of home-based FES, including recruitment, retention, adherence to prescribed treatment sessions, safety, and participants' ability to independently operate the device at home. Secondary evaluation will assess preliminary changes in functional walking ability using the 6-Minute Walk Test (6MWT), measured at baseline and after 12 weeks. The study is intended to generate feasibility and preliminary effectiveness data to inform the design of a future, adequately powered randomized controlled trial and to assess the potential for wider implementation of home-based FES rehabilitation for people recovering from stroke.

Outcome Measures

Primary Outcomes (1)

  • Primary Outcome Measure

    The primary outcome of this study is 6MWT, a validated measure of functional walking endurance and lower limb mobility in stroke survivors. Participants will be instructed to walk at their usual pace along a flat, unobstructed path for six minutes, with total distance covered recorded in meters. The 6 MWT will be conducted at baseline and at the end of the intervention period after 12 weeks.

    Baseline 12 weeks

Secondary Outcomes (1)

  • Secondary Outcome

    Baseline to 12 weeks.

Study Arms (2)

Home-Based FES

EXPERIMENTAL

Participants will receive home-based FES for lower-limb rehabilitation for 12 weeks.

Device: Functional Electrical Stimulation (FES)

Standard Rehabilitation

ACTIVE COMPARATOR

Participants will receive standard outpatient care and home-based rehabilitation without FES.

Other: Standard Rehabilitation

Interventions

Participants will receive standard outpatient care and home-based rehabilitation without FES, with equivalent remote clinician contact and education.

Standard Rehabilitation

FES will be applied to the quadriceps, tibialis anterior, and hamstrings for 30 minutes per session, 5 sessions per week, for 12 weeks, supported by a smartphone-based telerehabilitation platform for training, adherence monitoring, safety monitoring, and remote clinician support.

Home-Based FES

Eligibility Criteria

Age18 Years - 99 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 years with ischemic or hemorrhagic stroke (one month to one year post stroke)
  • Clinical evidence of mild to moderate lower-limb weakness, defined as Manual Muscle Test (MMT) grade 2 or 3 in one or more target muscle groups (e.g., tibialis anterior, quadriceps, hamstrings) on the affected side.
  • Cognitively able to follow instructions and provide informed consent (e.g., MMSE ≥ 24 or equivalent screening, or judged capable by the investigator).
  • Access to a compatible smartphone and home internet service and willing/able to use the tele-rehab app.
  • Skin at electrode application sites intact (no open wounds) and no dermatologic condition that would prevent safe application of the sleeve.

You may not qualify if:

  • Implanted electronic medical device contraindicated with FES (e.g., pacemaker, implantable cardioverter-defibrillator) or other metallic implants near stimulation site that the treating clinician deems a contraindication.
  • Active seizure disorder (epilepsy) that is uncontrolled or where stimulation could increase seizure risk, diabetes mellitus.
  • Pregnancy or breastfeeding.
  • Known allergy to materials used in the FES sleeve or electrodes.
  • Severe spasticity in target muscle groups (e.g., Modified Ashworth Scale ≥ 3) that prevents functional stimulation or safe participation.
  • Severe cardiovascular instability or uncontrolled medical conditions that make participation unsafe (e.g., unstable angina, recent myocardial infarction within 3 months, uncontrolled hypertension-systolic \>180 mmHg or diastolic \>110 mmHg at screening).
  • Severe cognitive impairment, active psychiatric illness, or communication barriers that preclude safe device use or reliable consent/assessment.
  • Open wounds, skin infection, severe dermatitis, or other skin conditions at electrode or sleeve contact sites.
  • Participation in another interventional trial that would conflict with outcomes or safety reporting for this sub study.
