Parkinson’s Disease (PD), a neurodegenerative disease, results from the loss of dopamine-secreting neurons within the basal ganglia, leading to deficits in motor function. The common symptoms of PD include rigidity, resting tremors, and bradykinesia. Large amplitude training is one treatment strategy to address bradykinesia, with demonstrated improvements in speed and amplitude of functional movements. Recently, amplitude training protocols, such as LSVT-BIG®, have been developed with set dosages and parameters; however, the evidence to support these specific parameters is limited. This presentation will analyze the current research on the effects of amplitude training based on protocol parameters such as type, intensity, and frequency of the intervention. This information will guide future research related to dosage and delivery of amplitude-based training protocols to individuals with PD.
