Trial Outcomes & Findings for Contralaterally Controlled FES for Hand Opening in Hemiplegic Cerebral Palsy (NCT NCT02925455)

NCT ID: NCT02925455

Last Updated: 2021-06-22

Results Overview

Participants played a game that required them to perform bimanual tasks while being video recorded. The amount of involvement of the affected arm is scored by viewing the video and converted into a logit score (0-100), with a higher value indicating a better outcome.

Stimulation + Video Games
Contralaterally-controlled functional electrical stimulation (CCFES) enables patients with upper extremity hemiplegia to open their paretic hand by stimulating finger and thumb extensors with surface electrodes. CCFES is used during functional task practice and hand therapy video games to link motor intent with execution. Four intuitive and engaging games were developed to provide goal-oriented motor skill training, impairment-appropriate difficulty, and performance feedback that motivates iterative play and skill improvement. Contralaterally-controlled functional electrical stimulation: Contralaterally-controlled functional electrical stimulation (CCFES) is electrical stimulation of weak muscles of an impaired limb controlled via movement of the unimpaired contralateral limb. Hand therapy video games: Hand therapy video games are designed to provide therapy to weak muscles of an impaired limb via goal-directed movements.
Video Games (no Stimulation)
Participants receive duration-matched, identical hand therapy video games and task practice therapy as the experiment arm, but do not receive CCFES to assist hand opening. Hand therapy video games: Hand therapy video games are designed to provide therapy to weak muscles of an impaired limb via goal-directed movements.

SECONDARY outcome

Timeframe: 2 time points: prior to treatment and at end of 6 weeks of treatment

Participants perform 14 test tasks that require reach, grasp, release, and manipulation of simple objects. A video of the test is recorded for scoring across the 30 score items using a three, four or five point scale (higher values indicating better outcomes). Item scores relating to four elements of movement are measured and summed within the corresponding sub-scale. A percentage of the total score (range 0-100%) for each subscale is computed and reported separately, with higher values indicating better outcomes.

Timeframe: 2 time points: prior to treatment and after 6 weeks of treatment

The Box and Blocks test counts how many times the participant can pick up 1 block at t time, move it over a partition, and release it in a target area within 60 seconds. The minimum score is 0. There is no maximum score. The average score of healthy individuals within the age range of this study ranges from 70 to 79. Higher scores are considered to be a better outcome. For each individual, the score prior to treatment was subtracted from the score at 6 months after completion of treatment. Then for each treatment group, these change scores were averaged.

Timeframe: 2 time points: prior to treatment start and at end of treatment week 6.

Finger movement tracking is a method of measuring motor control. The degree of finger extension will be displayed as a cursor on a computer screen, its vertical position corresponding to the degree of finger extension. A sinusoidal trace having a frequency of 0.1 Hz (1 cycle in 10 seconds) will scroll across the screen. The amplitude of the sine-wave track will be scaled so that it oscillates between 15% and 85% of the participant's full active finger extension. The participant will be seated with the wrist and forearm stabilized in a neutral posture. The participant's task is to keep the cursor on or as close to the scrolling trace as possible by extending and flexing their index finger. The vertical distance between the cursor and the target trace will be calculated for every time point of data collected. The error for each 30-sec trial will be the average vertical distance that is equivalent to a percentage of volitional range of motion.
