Maximum Cross-correlation Coefficient Primary · After 20 minutes of training under each perceptual cue condition

Cross-correlation between tangential velocity profiles of the two hands was used to index spatial and temporal coordination between hands. Cross-correlation measures similarities of two distinct time series as a function of the displacement of one relative to the other. Repeated correlations between the two hand velocity profiles were obtained as the velocity profile of one hand was successively lagged. The maximum cross correlation coefficient obtained gave a measure of similarity between the two profiles, indexing spatial coordination. The better the arms moved in space, the higher the score

Between Hands Time-lag Primary · After 20 minutes of training under each perceptual cue condition

Temporal coordination is about how well both arms move at the same time. Temporal coordination was quantified as the time lag at which the peak cross-correlation coefficient was obtained via cross-correlation analysis. If one arm moves a little later than the other, there's a time delay (or time lag). Shorter the delay, the better the timing between the arms. If the delay is positive, it means the weaker or less-used arm is moving after the stronger one.

Sponsor's own description

Significant difficulty in incorporating the weaker arm in daily activities after stroke is, in part, driven by difficulty in engaging both arms interactively in a coordinated manner. The current study aims to determine the nature of bimanual coordination deficits after stroke and takes initial steps to test a novel theory-driven approach to improve interactive bimanual coordination in patients with stroke. This project will advance stroke rehabilitation by identifying novel, scientifically-based strategies to improve the engagement of the weaker arm in coordinated and interactive bimanual actions of daily life, thus improving quality of life in individuals after stroke.
