Currently, occupational therapists lack an objective process for measuring the rehabilitation progress of patients suffering from hemiparesis, a weakness on one side of the body. This can result in inaccurate physician judgments that lead to ineffective treatment that is either too difficult for patients, resulting in frustration, or too easy for patients, resulting in slower progress. Bilateral Limb Assessment Technology (BLAsT) is targeting clinicians who work with pediatric patients that suffer from hemiparesis to provide them with systematic and quantitative measurements of patient performance. The project consists of both software and hardware components in the form of a user interface and wearable device. The design incorporates skeletal tracking, data visualization of metrics, and an IMU on a wearable device to track rotational measurement. The device accurately determines patient body positioning including upper body joint angles and degree of forearm rotation. The wearable device and software are integrated in a user-friendly graphical interface for occupational therapists at the Children’s Hospital of Philadelphia (CHOP) such as the team’s clinical advisor Dr. Todd Levy. Testing on both young adults and children as well as continuous contact with Dr. Levy will ensure the device is progressing to meet clinical needs.
