Trial Outcomes & Findings for Concomitant Sensory Stimulation During Therapy to Enhance Hand Functional Recovery Post Stroke (NCT NCT04569123)

NCT ID: NCT04569123

Last Updated: 2026-02-09

Results Overview

The Wolf Motor Function Test (WMFT) is a standardized, timed assessment of upper extremity motor function. This study reports the total average movement time across the WMFT tasks. Range: 0 seconds to \>120 seconds (no fixed upper limit). Interpretation: Lower movement times indicate better motor function. Only this WMFT movement-time variable was analyzed as the pre-specified primary outcome.

Vibration
The device will deliver imperceptible vibration for the treatment group. real stimulation: Participants will undergo standardized hand task practice therapy (3 sessions/week for 6 weeks) with the watch worn on the paretic wrist. Participants will be randomized into two groups: The device will deliver vibration for the treatment group.
No Vibration
The device will deliver no vibration for the control group. No stimulation: Participants will undergo standardized hand task practice therapy (3 sessions/week for 6 weeks) with the watch worn on the paretic wrist. Participants will be randomized into two groups: The device will deliver no vibration for the control group during therapy.

SECONDARY outcome

Timeframe: Baseline and 6 weeks

The Box and Blocks Test (BBT) measures unilateral gross manual dexterity. Participants move as many blocks as possible from one side of a box to the other in 60 seconds. Range: 0-150 blocks (typical). Interpretation: Higher scores indicate better manual dexterity.
