Article excerpt

Rett syndrome (RTT) is a neuro-developmental disability affecting mostly women. Many diagnosed with this disorder represent an extreme "fear of movement" debilitating the desire for movement, thereby reducing function. Despite the fact that "fear of movement" is usually associated with a vestibular deficit, the clinical experience with this population, suggests a strong influence of the proprioceptive system in regards to fear of movement.

Goal: To identify the sensory system responsible for the fear of movement in this group of clients.

Methods: 10 participants with RTT were positioned in a prone position in a vestibular plate. Each received a vestibular and a proprioceptive stimulus. Participant's response was evaluated through the use of the Facial Action Coding System (FACS) and the Pain and Discomfort Scale (PADS).

Results: High and statistically significant (P=0.05) responses were observed by the participants when exposed to proprioceptive stimulus in comparison to reaction to the vestibular stimulus in both scales. …
