How does LSVT BIG address the motor disorder of hypokinesia/bradykinesia?

LSVT BIG specifically targets the motor disorder of hypokinesia and bradykinesia by scaling up the amplitude of motor output through bigger movements. This approach is vital because individuals with Parkinson's disease often experience reduced range of motion and difficulty initiating movements, which are characteristic of these motor disorders. By encouraging patients to increase the size and amplitude of their movements, LSVT BIG aims to counteract the symptoms of diminished movement. The principle behind this technique is that larger movements involve more muscle activation and can help retrain the brain and nervous system to initiate and sustain those movements more effectively.

In contrast, focusing on fine motor skills does not directly address the overarching issue of reduced amplitude and can miss the broader goals of improving overall movement quality and function. While relaxation techniques may be beneficial for managing stress or anxiety, they do not specifically target the motor symptoms central to hypokinesia and bradykinesia. Similarly, while electrical stimulation can have its uses in rehabilitation, it does not align with the core principles of LSVT BIG, which emphasizes voluntary movement practices rather than reliance on external devices for motor function enhancement.
