Examining the effects of amplitude-based training as a component of the plan of care in an individual with olivopontocerebellar atrophy.

Background: Amplitude-based exercise training has been shown to be effective in the motor performance of individuals with idiopathic Parkinson's disease, with limited research investigating its effects on Parkinson plus syndromes such as olivopontocerebellar atrophy (OPCA). The purpose of this clinical case report is to examine the effects of amplitude-based training exercises on an individual with OPCA.

Case Description: A 68-year-old man with a 14-month history of OPCA presented to physical therapy with bradykinesia, rigidity, and postural instability.
