About this trial
Associative Peripheral Stimulation (APS) is a non-invasive therapy intended for stroke rehabilitation involving transcutaneous electrical muscle stimulation paired with voluntary movement. This pilot study investigates whether APS applied during the acute phase of stroke recovery may reduce impairment and improve function in the affected upper extremity.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Confirmed ischemic or hemorrhagic stroke no earlier than 7 days prior to enrollment;
Presentation of hemiparesis or paralysis of the upper extremity due to stroke;
Ability to comprehend and follow study instructions;
Ability to initiate finger extension (≥3°) at least three times per minute;
Disqualifiers
Contraindications, intolerance, or high sensitivity to the experimental protocol;
History of upper-extremity disability prior to the index stroke;
Neurological conditions (other than stroke) affecting motor function;
Treatment of spasticity/increased tone in the affected upper extremity (e.g., with Botox injection);

Treatment groups
Trial outcomes
Primary outcomes
Maximum Average of Range of Motion (ROM)
Measure of distal extensor function (wrist and fingers). Unit of measurement: degrees (°). Higher scores indicate better outcomes.
Fugl-Meyer Assessment Upper-Extremity (FMA-UE)
Measure of motor recovery in stroke patients with hemiparesis. Scoring range: 0 to 66. Higher scores indicate better outcomes.
Secondary outcomes
Maximum Average of Range of Motion (ROM)
Measure of distal extensor function (wrist and fingers). Unit of measurement: degrees (°). Higher scores indicate better outcomes.
Fugl-Meyer Assessment Upper-Extremity (FMA-UE)
Measure of motor recovery in stroke patients with hemiparesis. Scoring range: 0 to 66. Higher scores indicate better outcomes.
Action Research Arm Test (ARAT)
Measure of four functional domains: grasp, grip, pinch, and gross arm movement. Scoring Range: 0 to 57. Higher scores indicate better outcomes.
