According to research, what is the lasting effect of LSVT LOUD treatment in Parkinson's Disease?

The LSVT LOUD treatment, which is designed to improve voice and speech in individuals with Parkinson's Disease, demonstrates significant lasting effects, particularly for durations extending up to two years following the intervention without additional treatment. Research indicates that after completing the LSVT LOUD program, patients can maintain meaningful improvements in vocal loudness and speech clarity for this period, reflecting the effectiveness and sustainability of the treatment.

The underlying principle of the LSVT LOUD approach is focused on neuroplasticity, where consistent vocal practice during the treatment can lead to lasting changes in the brain, allowing individuals to retain the benefits of enhanced vocal skills far beyond the initial therapy sessions. This long-term effect emphasizes the importance of the techniques learned during therapy and their integration into daily communication practices, allowing individuals with Parkinson's to engage more fully in their social interactions.
