Per-arm endpoint measurements with 95% confidence intervals where reported. Source: trial results section.

Fugl-Meyer Assessment Upper Limb Portion Primary · Post-treatment-Phase 1 (month 3-6 post-stroke), post-crossover treatment-Phase 2 (month 5-7 post-stroke).

Comprehensive measure of upper limb impairment; minimum score = 0, maximum score = 66; higher score means better outcome. Outcome measure represents the difference between post-treatment and baseline (i.e., change score). Intent is to report a change from baseline to post-treatment Phase 1 for both Test Group subjects and Control Group subjects, and to report a change from post-treatment Phase 1 to post-crossover treatment Phase 2 for Control Group subjects who elected to cross over.

Stroke Impact Scale Secondary · Post-treatment-Phase 1 (month 3-6 post-stroke), post-crossover treatment-Phase 2 (month 5-7 post-stroke).

Activities of daily living questionnaire for stroke patients. Minimum overall score = 0, maximum overall score = 800. Higher scores mean better outcome. Intent is to report a change from baseline to post-treatment Phase 1 for both Test Group subjects and Control Group subjects, and to report a change from post-treatment Phase 1 to post-crossover treatment Phase 2 for Control Group subjects who elected to cross over.

Rancho Los Amigos Functional Test Secondary · Post-treatment-Phase 1 (month 3-6 post-stroke), post-crossover treatment-Phase 2 (month 5-7 post-stroke).

Upper limb functional movement. Outcome measure indicates how many of 17 functional tasks could be completed. Minimum score = 0, maximum score = 17. Higher number means better outcome. Intent is to report a change from baseline to post-treatment Phase 1 for both Test Group subjects and Control Group subjects, and to report a change from post-treatment Phase 1 to post-crossover treatment Phase 2 for Control Group subjects who elected to cross over.

Spasticity (Modified Ashworth) Scale Secondary · Post-treatment-Phase 1 (month 3-6 post-stroke), post-crossover treatment-Phase 2 (month 5-7 post-stroke).

Joint impedance of the fingers+wrist combined and that of the elbow. Outcome measure consists of the sum of 4 scores: (1) hand/wrist flexion, (2) hand/wrist extension, (3) elbow flexion, (4) elbow extension. Minimum value = 0, maximum value = 20. Higher score means worse outcome. Intent is to report a change from baseline to post-treatment Phase 1 for both Test Group subjects and Control Group subjects, and to report a change from post-treatment Phase 1 to post-crossover treatment Phase 2 for Control Group subjects who elected to cross over.

Active Motion Test Grasp Secondary · Prior to each treatment session. Post-treatment-Phase 1 (month 3-6 post-stroke), post-crossover treatment-Phase 2 (month 5-7 post-stroke).

Ability to track a moving target with active grasp extension and flexion, measured as the total time in the target, in seconds. Outcome measure represents the change score from baseline to post-treatment. Minimum score = 0, maximum score = 40 s. Higher scores indicate better outcome. Intent is to report a change from baseline to post-treatment Phase 1 for both Test Group subjects and Control Group subjects, and to report a change from post-treatment Phase 1 to post-crossover treatment Phase 2 for Control Group subjects who elected to cross over.

Adverse events — posted to ClinicalTrials.gov

Time frame: Adverse event data were collected over a period of each participant's period of participation in the study. For participants in the Test group, and those in the Control group who chose not to cross over, the time frame was 6-9 weeks. For those Control group participants who crossed over, the time frame was 9-14 weeks.. Reporting threshold: 0%. Adverse-event reports describe events observed during the trial — not all are caused by the drug.

Sponsor's own description

The AMES device is designed to produce functional cortical changes by:(1) assisting the subject as he/she attempts to move the limb (assisted movement) and (2) enhancing movement sensation by vibrating the muscles during movement (enhanced sensation). The primary hypothesis is that the combination of assisted movement and enhanced sensation from muscle vibration can increase the amount of motor recovery in individuals disabled by a stroke.
