Journal of Neurology, Neurosurgery & Psychiatry, 09/23/2009Almeida QJ et al.
The results support the notion that some occurrences of freezing may be the result of an underlying perceptual mechanism that interferes with online movement planning. Neither healthy individuals nor individuals with PD absent of FOG exhibited this same effect.

The article highlights the importance of "thinking outside-the-box". Although motor impairments can be identified in many different neurological diseases, it is important to question whether there may be underlying sensory or perceptual mechanism that may be linked to motor impairment. In some cases, it may be critical to treat the underlying mechanism, in order to improve motor symptoms.
