The goal of this study is to determine the effectiveness of behavioral support and feedback from a wearable device that senses arm movement in improving upper extremity function in a pilot, randomized controlled trial with chronic stroke patients
In this randomized controlled trial, the investigators will evaluate two telerehabilitation strategies for increasing arm use at home: a smartwatch app and a psychological intervention. The psychological intervention aims to address ambivalence and enhance motivation, while the smartwatch provides feedback on arm movement variability. The investigators hypothesize that combining the psychological intervention with smartwatch feedback will lead to greater improvements in arm use and upper extremity recovery
Inclusion Criteria: * 18 to 85 years of age * Experienced a single or multiple, ischemic or hemorrhagic stroke, with unilateral weakness, over six months previously * An ability to score at least 3 blocks on the Box and Block Test. BBT score of the affected arm is at least 5% worse than that present with the unaffected arm. * Absence of major depression, as defined by DSM V criteria or a score on the Geriatric Depression Scale \< 10. Exclusion Criteria: * Any substantial decrease in alertness, language reception, or attention * Single or multiple, ischemic or hemorrhagic stroke less than 6…
This app measures movement variability in the upper extremity as described in our previous study (doi:10.3390/s24165266).
The other software we are using measures total active time of the upper extremity.
Motivational Interviewing is an established therapeutic technique designed to increase patient adherence to therapy by addressing ambivalence. The motivational Interviewing sessions will include a variety of techniques such as: Open ended questions, Active Listening, Affirmation, Summarization, Questions focused on change talk, and Providing Information.
