TENS for Limb Function in Stroke: Design and Rationale for a Randomized Trial
Sponsor: CHENGNING Song
Summary
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.

Conditions
Interventions
Low-frequency(2HZ) TENS
Participants receive transcutaneous electrical nerve stimulation (TENS) at a frequency of 2Hz. The stimulation is delivered using surface electrodes placed on the affected upper limb. Each session lasts 30 minutes and is conducted three times per week for a total of 8 weeks. Intensity is gradually increased from 1 mA to 3 mA during each session.
High-frequency(100HZ) TENS
Participants receive TENS at a frequency of 100Hz using the same electrode placement and schedule as the 2Hz group. Sessions last 30 minutes, three times weekly for 8 weeks, with intensity increasing from 1 mA to 3 mA across the session. This group represents high-frequency stimulation.
Placebo TENS
Participants use a TENS device identical in appearance to the active treatment units. The power light is on, but no electrical stimulation is delivered due to internal circuit disconnection. Sessions follow the same schedule and duration as the active groups.
