What this trial studies
This study investigates the effects of transcutaneous electrical nerve stimulation (TENS) on patients who have experienced a stroke resulting in hemiparesis. Participants will attend a minimum of 15 sessions over four months, where they will undergo various tests to assess reflex behaviors, motor tract influences, and functional movement adaptations. The study aims to collect and analyze data to evaluate the efficacy of TENS in improving mobility and motor function in post-stroke patients.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 to 80 who have experienced a single unilateral stroke more than six months ago and can walk as part of daily activities.
Not a fit: Patients with severe concurrent medical conditions, cognitive deficits, or recent Botox injections in the lower extremity may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could enhance mobility and functional recovery for stroke patients with lower limb hemiparesis.
How similar studies have performed: While the use of electrical stimulation in rehabilitation is not entirely novel, the specific application of TENS for this patient population is less explored, making this study a potentially significant contribution to the field.
