Spasticity assessment system for elbow flexors/extensors: Healthy pilot study

摘要

This paper describes initial testing of a spasticity assessment system for passive elbow flexion/extension motions using a robotic manipulator. Quantitative force data was collected from healthy individuals. As repetition and speed were increased, significant differences in measured force were found in a study with a high speeds (n=48), but were not found in a study with a lower speeds (n=52). This result assists clinicians who now possess a baseline of healthy data to which quantitative patient data can be compared. Future developments include contrasting healthy baseline values to clinical trial data from individuals with stroke or acquired brain injury.
