Stroke Wearable Operative Rehabilitation Device Impact Trial

Not Applicable

Completed

• Conditions: Ischemic Stroke; Upper Extremity Hemiparesis
• Interventions: Device: Only 3D movement analysis; Device: Vibratory feedback and 3D movement analysis

• Registration Number: NCT01967290
• Lead Sponsor: Centro Hospitalar de Entre o Douro e Vouga

Brief Summary

The objective of this study is to determine the impact of vibratory feedback on the quality and intensity of a common motor rehabilitation task of the upper-arm (hand-to-mouth) in stroke patients. For that purpose the investigators use the SWORD system that combines 3D motion quantification wearable sensors and a vibratory module.

The investigators hypothesize that vibratory stimuli during a motor rehabilitation task increase significantly the number of correct movements performed per unit of time.

The design of the study is a cross-over randomized clinical trial. With the SWORD system in place each patient will perform the hand-to-mouth task twice (with vibratory feedback and without it), the order being random. The number of correct movements and other motor outcomes will be assessed continuously under both conditions.

Arm && Interventions

Group	Intervention	Description
Hand-to-mouth task - no vibratory feedback	Only 3D movement analysis	Hand-to-mouth task in the same conditions as the experimental arm but without vibratory feedback, only 3D movement analysis. The SWORD device is in place over the patient arm, performs continuous 3D movement analysis but does not provides vibratory feedback according to quality performance settings established by the clinician after patient assessment. If movement is of lower amplitude or slower than prescribed NO vibratory stimulus is delivered at the wrist of the patient. The intervention is repeated on the hemiparetic and normal sides and the duration of the task is defined according to the patient cardiovascular status.
Hand-to-mouth task - vibratory feedback	Vibratory feedback and 3D movement analysis	Hand-to-mouth task under vibratory feedback and 3D movement analysis. The SWORD device is in place over the patient arm, performs continuous 3D movement analysis and provides vibratory feedback according to quality performance settings established by the clinician after patient assessment. If movement is of lower amplitude or slower than prescribed a vibratory stimulus is delivered at the wrist of the patient. The intervention is repeated on the hemiparetic and normal sides and the duration of the task is defined according to the patient cardiovascular status.

Primary Outcome Measures

Name	Time	Method
Number of correct movements	At the end of each hand-to-mouth task.	Number of correct movements performed within the duration of each hand-to-mouth task.

Secondary Outcome Measures

Name	Time	Method
Time between correct movements in seconds	At the end of each hand-to-mouth task.	Average, standard deviation and variance of the time between correct movements, measured in seconds, of all the correct movements performed during the duration of each hand-to-mouth task.
Cumulative amplitude of correct movements in degrees	At the end of each hand-to-mouth task	Sum of the amplitudes of all correct movements performed within the duration of each hand-to-mouth task.
Number of pause events during the task	At the end of each hand-to-mouth task	Number of episodes during the execution of each hand-to-mouth task where the patient stopped doing movements and/or the time between correct movements exceeded the mean plus one standard deviation measured within the same hand-to-mouth task.
Total number of movements	At the end of each hand-to-mouth task.	Total number of correct and incorrect movements performed within the duration of each hand-to-mouth task.
Range of motion in degrees	At the end of each hand-to-mouth task.	Average, standard deviation and variance of the range of motion, measured in degrees, of all the correct movements performed during the duration of each hand-to-mouth task.
Cumulative amplitude of all movements performed in degrees	At the end of each hand-to-mouth task.	Sum of the amplitudes of all correct and incorrect movements performed within the duration of each hand-to-mouth task.
Fatigue	At the end of each hand-to-mouth task.	Assessment of fatigue by the patient through an analogic scale from 0 (no fatigue) to 4 (interruption due to fatigue).
Pain	At the end of each hand-to-mouth task.	Assessment of pain by the patient through an analogic scale from 0 (no pain) to 4 (interruption due to pain).
Number and type of other distresses	At the end of each hand-to-mouth task.	Recording and description of any kind of discomfort reported by the patient or detected through vital parameter and arterial oxygen saturation monitoring.
