Trial Outcomes & Findings for MyHand: An Active Hand Orthosis for Stroke Patients (NCT NCT03767894)

NCT ID: NCT03767894

Last Updated: 2020-11-05

Results Overview

The ARAT is a 19-item measure that assesses upper limb functioning. The ARAT is divided into 4 sub-tests (grasp, grip, pinch, and gross arm movement). Performance on each item is rated on a 4-point ordinal scale ranging from 0 (cannot perform) to 3 (normal performance). Scores on the ARAT range from 0-57 points, with higher scores indicating better performance.

Measure
MyHand Orthosis
Subjects are trained to control and use the MyHand orthosis either with a shoulder harness or an EMG band. The MyHand orthosis aims to aid in fine motor skills such as picking up and holding items of varying shape, size and weight. EMG Band: The MyHand orthosis provides tension to the digits to open the fingers on demand. This group will wear an EMG band to control and activate the MyHand orthosis. Shoulder harness: The MyHand orthosis provides tension to the digits to open the fingers on demand. This group will wear a shoulder strap to control and activate the MyHand orthosis, either with shoulder elevation or shoulder depression.

Timeframe: Baseline; Post-test at Week 4

The Fugl-Meyer (FM) Assessment of Motor Recovery evaluates and measures recovery in post-stroke hemiplegic patients. The FM uses a 3-point ordinal scale from 0 (cannot perform) to 2 (performs fully). The FM has 5 domains with a maximum score of 226 points. Subscales can be administered with out using the full FM. The Upper Extremity component (UEFM) consists of 33 items with a score range of 0-66. Higher score indicate better performance. Please note: An a prior decision was made to only perform the UEFM once at post-testing: post test without robotic assistance. The UEFM assesses capacity of the arm primarily through gross motor tasks, and comparatively few grasping and pinching tasks. Thus, it was presumed that robotic assistance would have minimal influence on UEFM scores. In other words, the UEFM was intended as a outcome measure to primarily evaluate the rehabilitative effects of training with the device, as opposed to evaluating the assistive capacity of using the device.

SECONDARY outcome

Timeframe: Baseline

Population: Baseline scores on MAS. Only the 11 subjects that completed the study were included in this analysis.

The Ashworth or Modified Ashworth Scale (MAS) is a measure of spasticity originally developed as a simple clinical classification to assess the anti-spastic effects of carisoprodol in multiple sclerosis. It is rated on a 5-point nominal scale using subjective clinical assessments of tone ranging from 0 (no increases in tone) to 4 (limb rigid in flexion/extension or abduction/adduction). Please note: MAS is officially scored on a 5-point scale that includes "1+" (full range: 0, 1, 1+, 2, 3, 4). However non-numeric scores are not allowable in the Outcome Measure Data Table. Therefore, the scores were transformed from a 0-4 scale (including 1+) to a 0-5 scale (excluding 1+). The reported medians for all but Finger Flexors were not impacted by the scale transformation. Finger Flexor median is reported as 2 in the Outcome Measure Data Table, but this can be understood as a true median of 1+ if using the original MAS scoring scale.

Timeframe: Baseline; Post-test at Week 4

Population: Only the 11 subjects that completed the study were included in this analysis.

The BBT measures unilateral gross manual dexterity using blocks and a 2-compartment box. At the start, there are 150 blocks in one compartment and the score represents the number of blocks transferred from one compartment to the other compartment in 60 seconds. Each hand is scored separately, however only scores for the impaired (hemiplegic) hand are reported. Scores can range from 0-150, with higher scores indicating better performance of manual dexterity.
