Head position control strategies in progressive Supranuclear Palsy versus Idiopathic Parkinson's Disease during dynamic-on-static platform tilt.

ABSTRACT:

Objectives

We investigated differences in head stabilization among Progressive Supranuclear Palsy (PSP), advanced Idiopathic Parkinson's Disease (IPD) and healthy controls during passive anteroposterior platform tilting to determine factors for disease-specific falling.

Methods

Seventeen PSP, eleven IPD and eighteen control subjects were exposed to pseudorandom multi-frequency antero-posterior platform tilts, while recording 3D motion of body segments with a Zebris ultrasound positioning system. Fourier transforms were computed from the time series datasets to assess transfer functions between stimuli (platform tilts) and responses (angles of the head, trunk and hip in space).

Results

Overall head excursions in space among PSP was several times increased in relation t
