    Objective: The article proposes a set of metrics for evaluation of patient performance in physical therapy exercises. Methods: Taxonomy is employed that classifies the metrics into quantitative and qualitative categories, based on the level of abstraction of the captured motion sequences. Further, the quantitative metrics are classified into modelless and model-based metrics, in reference to whether the evaluation employs the raw measurements of patient performed motions, or whether the evaluation is based on a mathematical model of the motions. The reviewed metrics include root-mean square distance, Kullback Leibler divergence, log-likelihood, heuristic consistency, Fugl-Meyer Assessment, and similar. Results: The metrics are evaluated for a set of five human motions captured with a Kinect sensor. Conclusion: The metrics can potentially be integrated into a system that employs machin.. View More»
