Effects of external and internal cues on gait function in Williams syndrome

Effects of external and internal cues on gait function in Williams syndrome:

"Although the WS and DS groups were able to achieve the criterion and normalize stride length in both conditions, the WS group significantly reduced their gait speed and cadence in the externally cued condition when compared to controls. In the internally cued condition, the WS group also showed reduced speed and increased intra-individual variability in speed and stride time. These findings suggest that the primary deficit is not one of difficulty regulating stride length in WS, but rather indicates more widespread dysfunction within visuomotor regions."
