Relative accuracy of time and frequency domain features to quantify upper extremity coordination

Upper limb coordination is necessary for the performance of activities of daily living (ADLs). This coordination is impaired in individuals suffering from motor deficits. The evolution of inter- and intra-limb coordination patterns may provide insight into mechanisms of recovery. In this paper, we investigate the ability of inertial sensors to capture measures of limb coordination in non-disabled individuals during the performance of ADL inspired tasks. We evaluate limb coordination as measured by time and frequency domain features extracted from inertial sensors for a subset of upper limb tasks, and evaluate the relative sensitivity of these measures to different task types.
