Capture, learning, and classification of upper extremity movement primitives in healthy controls and stroke patients

Abstract: There currently exist no practical tools to identify functional movements in the upper extremities (UEs). This absence has limited the precise therapeutic dosing of patients recovering from stroke. In this proof-of-principle study, we aimed to develop an accurate approach for classifying UE functional movement primitives, which comprise functional movements. Data were generated from inertial measurement units (IMUs) placed on upper body segments of older healthy individuals and chronic stroke patients. Subject… Show more

“…We developed the taxonomy using videotaped recordings of 16 subjects (healthy and stroke-impaired) performing various ADL-like tasks; an early iteration has been previously described (29). For the refined taxonomy, we examined validity and reliability using new motion data generated by healthy and stroke-impaired subjects (see Table 2 for demographic and clinical details) performing various activities (see Table 3 for task parameters).…”

“…al, developed a movement classification system that could be used to enumerate repetitions and applied the system to stroke patient data, but focused on the classification of movement primitives (components of arm movements that cannot be broken down further) rather than the exercises themselves. 15 To our knowledge, this study is the first to explore the application of upper extremity exercise classification and repetition counting on exercise data in inpatients with recent stroke.…”

“…They report lower rates of accuracy (precision of approximately 80% in control patients, 79% in patients with weakness due to stroke) than in our study. 20 While speci cs about the particular UE movements studied (exercises versus movement primitives) may have contributed to this observed difference in accuracy, it is important to note that we also used a different categorization and repetition counting strategy. In our algorithm, activity is rst classi ed and then number of repetitions is estimated by counting peaks in data from the sensor that was previously seen to have maximum uctuations during the course of the exercise.…”
