LSVT LOUD® is an effective speech treatment for individuals with Parkinson disease (PD) and other neurological conditions. LSVT LOUD, named for Mrs. Lee Silverman (Lee Silverman Voice Treatment – LSVT) was developed in 1987 and has been scientifically studied for nearly 20 years with funding support from the National Institute for Deafness and other Communication Disorders (NIDCD) of the National Institutes of Health. Published research data support improvements in vocal loudness, intonation, and voice quality for individuals with PD who received LSVT LOUD, with improvements maintained up to two years after treatment. Recent research studies have also documented the effectiveness of this therapy in improving the common problems of disordered articulation, diminished facial expression and impaired swallowing. Additionally, two brain imaging studies have documented evidence of positive changes in the brain following administration of the therapy.
LSVT LOUD improves vocal loudness by stimulating the muscles of the voice box (larynx) and speech mechanism through a systematic hierarchy of exercises. Focused on a single goal “speak LOUD!” – the treatment improves respiratory, laryngeal and articulatory function to maximize speech intelligibility. The treatment does not train people for shouting or yelling; rather, LSVT LOUD uses loudness training to bring the voice to an improved, healthy vocal loudness with no strain.
Recently principles of LSVT LOUD® were applied to limb movement in people with Parkinson disease (LSVT BIG®) and have been documented to be effective in the short term. Specifically, training increased amplitude of limb and body movement (Bigness) in people with Parkinson disease has documented improvements in amplitude (trunk rotation/gait) that generalized to improved speed (upper/lower limbs), balance, and quality of life. In addition, people were able to maintain these improvements when challenged with a dual task.
