What happens when the LSVT BIG protocol is adapted or customized by providing increased support or changing patient positions?

When the LSVT BIG protocol is adapted or customized, such as by providing increased support or changing patient positions, it fundamentally alters the structure and implementation of the intervention. The LSVT BIG protocol is a specific evidence-based treatment designed for individuals with Parkinson's disease that focuses on increasing amplitude of movement through prescribed exercises and activities. When this protocol is modified significantly, it is no longer adhering to the original principles and techniques established by the LSVT BIG framework, which are crucial for its effectiveness and outcomes. By customizing it to such a level, it transitions into a different intervention altogether, no longer representing the standardized approach that is essential for maintaining the integrity and benefits associated with LSVT BIG therapy.

The other options do not accurately capture the implications of substantial modification to the protocol. Enhancements to treatment effectiveness or alignment with interdisciplinary models may be beneficial but do not justify deviations from the established protocol. Adapting LSVT BIG's protocol therefore results in a divergence from its intended use and classification.
