AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults recovering from a recent stroke who have some movement in the weak arm. It tests slow and fast TENS nerve stimulation to improve arm movement.

Age
The criteria list 18 to 85 years, but the record's age limits say 40 to 80 years.
Sex
All sexes can join.
Disease stage
Stroke (ischemic or hemorrhagic) diagnosed within the past 10 days to 2 months. Some voluntary movement in the non-weak arm and at least minimal antigravity movement in the weak shoulder. At least 5 degrees of active wrist extension on the weak side.

Main reasons for not taking part

  • Uncontrolled medical, heart or bone and joint conditions
  • Contraindications to TENS, such as an implanted cardiac pacemaker or skin allergies
  • Receptive aphasia that prevents informed consent or cooperation
  • Significant peripheral neuropathy affecting the arms
  • Severe contractures in the shoulder, elbow, wrist or fingers

About the trial

What the trial wants to find out

This study tests whether slow or fast electrical nerve stimulation (TENS) works better to improve arm movement in people recovering from a stroke. Participants will receive TENS on their weak arm three times a week for eight weeks. The results will help find the best TENS setting to support stroke recovery.

The 4 groups in the trial

  • 2Hz TENS GroupTreatment being tested

    Treatment: Low-frequency(2HZ) TENS

  • 100Hz TENS GroupTreatment being tested

    Treatment: High-frequency(100HZ) TENS

  • Placebo TENS GroupPlacebo, for comparison

    Treatment: Placebo TENS

  • No-treatment Control GroupNo study treatment, for comparison

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
