How does LSVT BIG affect motor output in Parkinson's patients?

LSVT BIG is specifically designed to enhance motor output in individuals with Parkinson's disease by focusing on larger amplitude movements. This approach is grounded in the understanding that patients often experience a reduction in movement amplitude, a symptom known as hypokinesia. The program encourages patients to amplify their movements, which is thought to help retrain the brain and improve overall motor function.

Incorporating larger and more coordinated movements can also aid in counteracting the rigidity and stiffness often associated with Parkinson's. Through this emphasis on big movements, patients learn to overcome their natural tendencies to move smaller and "diminished," thus improving their functional mobility and overall quality of life.

Other approaches that center on limiting movement range or scaling down complexity are contrary to the principles of LSVT BIG, which seeks to empower patients to move more robustly and confidently. Moreover, verbal instruction is crucial in this training to guide and reinforce the concept of "bigger" movements, thus making the emphasis on eliminating verbal cues inconsistent with the aims of LSVT BIG.
