What is the purpose of stimulability testing in LSVT BIG?

Stimulability testing in LSVT BIG is primarily performed to determine if larger amplitude movements can be produced by the individual. This form of testing assesses whether a person can increase the size of their movements when prompted or supported, which is a key component of the therapy's approach to improving motor function in individuals with Parkinson's disease and other movement disorders.

By evaluating the ability to produce these larger movements, clinicians can establish a baseline for further therapy, identify potential areas for improvement, and tailor treatment plans to better meet the needs of the individual. This assessment is crucial for determining the effectiveness of the therapeutic techniques employed in LSVT BIG and guiding the patient toward achieving the larger amplitude movements necessary for functional mobility.
