Trial Outcomes & Findings for Restoring High Dimensional Hand Function to Persons With Chronic High Tetraplegia (NCT NCT03482310)
NCT ID: NCT03482310
Last Updated: 2026-02-20
Results Overview
The success rate for achieving a series of specified grasp patterns will be calculated. This will be a percentage of the target grasp patterns successfully achieved. The reported outcome is an average of the outcomes (mean +/- standard deviation) over the full assessment period
COMPLETED
NA
1 participants
Outcomes were assessed on average every 3 months for the full time (4 years) that the participant was enrolled in the study.

Cortical Control of Grasp Patterns
Participants will be asked to think about holding different shaped objects, and the recorded cortical signal patterns will be decoded to match those grasp shapes
Using the Neuroport cortical recording array to determine the desired grasp pattern for a functional electrical stimulation (FES) system: Participants will be asked to think about holding different shaped objects, and the recorded cortical signal patterns will be decoded to match those grasp shapes
