Non-invasive therapy to improve motor function after stroke

Pilot Randomized Controlled Trial Assessing Associative Peripheral Stimulation (APS) for Reduction of Motor Impairment During Acute Period of Stroke Recovery

Not applicable Interventional APS Trial Group · NCT06575140

This study is testing a new non-invasive therapy called Associative Peripheral Stimulation to see if it can help people who have had a stroke improve their arm and hand movement during their recovery.

What this trial studies

This pilot study investigates the use of Associative Peripheral Stimulation (APS), a non-invasive therapy that combines transcutaneous electrical muscle stimulation with voluntary movement, to aid in stroke rehabilitation. The focus is on patients who have experienced an ischemic or hemorrhagic stroke within the last week and are exhibiting hemiparesis in their upper extremities. The study aims to determine if APS can effectively reduce motor impairment and enhance functional recovery during the acute phase of stroke recovery.

Who should consider this trial

Good fit: Ideal candidates are individuals who have suffered a stroke within the past week and have upper extremity hemiparesis.

Not a fit: Patients with prior upper extremity disabilities or other neurological conditions affecting motor function may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly improve motor function and rehabilitation outcomes for stroke patients.

How similar studies have performed: While the approach of using APS is relatively novel, similar non-invasive therapies have shown promise in improving rehabilitation outcomes in stroke patients.
