Cerebral Stroke
Conditions
Brief summary
The goal of this study is to determine the effectiveness of interactive feedback from a wearable device that senses hand function, the Manumeter, in improving upper extremity function in a pilot, randomized controlled trial with chronic stroke patients
Detailed description
In this randomized controlled trial, the investigators will compare two groups of chronic stroke participants Group 1 of study participants will use the Manumeter with interactive functions to monitor and motivate upper extremity functional activity. Group 2 of study participants will use the Manumeter but receive no feedback and will be given the current standard-of-care, a booklet describing a home exercise program for increasing upper extremity exercise. The investigators hypothesize that study participants who interactively monitor functional activity with the Manumeter will improve their upper extremity function significantly more.
Interventions
DEVICEManumeter
A manumeter is a first-of-its-kind magnetic sensor to wirelessly detect hand and arm movement in a socially acceptable and easy to don package. The study participants will wear a small magnet as a ring, and a sensing/logging wristband detects changes in the magnetic field as the ring moves; the wristband can detect arm accelerations.
