Lee Silverman Voice Treatment (LSVT) An intensive treatment program for individuals with Parkinson’s Disease Presented by: Laura Dinges
Characteristics of Parkinson’s Disease w w w w Affects both speech and voice Exhibits common form of hypokinetic dysarthria Decreased loudness Monotone Vocal tremor Hoarseness Rapid rate of speech 2
LSVT background w 1 st effective treatment for voice and speech disorders of people with Parkinson’s Disease (PD) w Developed in 1987 by Dr. Lorraine Ramig and Carolyn Mead, both speech-language pathologists w Named after one of the 1 st patients to receive treatment 3
LSVT background (cont. ) w Began as a treatment program for PD, now includes other neurological disorders w Intensive behavioral treatment is 4 days a week for 4 weeks (16 sessions) w Patients also asked to practice at home 4
LSVT techniques w Techniques intended to help patients with PD increase intelligibility and vocal loudness w Program emphasizes ‘loud’ speech w 5 basic concepts of program: n n n Think loud; Think shout Speech effort has to be high Must be intensive treatment Must be able to recalibrate loudness level Quantifiable improvements over time 5
Additional Information on LSVT w Program targets immediate improvement following treatment and also on developing skills for longterm maintenance. w Must be trained and certified s-lp to administer treatment w 400+individuals with PD have been successfully treated in efficacy research studies w Approx. 90% of patients with PD improve from treatment 6
PET brain images and LSVT w Study from Neurology journal by Liotti and colleagues (2003) w Looked at brain activity before and after voice treatment with LSVT using PET images w 5 patients with mild to moderate PD and speech disorders; 5 healthy subjects w PET images produced in 5 patients with PD during phonation and reading exercises before and after a cycle of LSVT 7
PET brain images and LSVT (cont. ) w 5 healthy subjects-images generated during same activities w Before treatment: In patients with PD, motor and pre-motor cortex activated (voluntary effort) w In healthy subjects, automatic circuits activated, especially basal ganglia w After treatment, patients’ images appeared more similar to healthy individuals’ images 8
Summary w 1. 5 million people are diagnosed with PD in the US w Individuals with PD often exhibit certain speech and voice characteristics w LSVT-1 st effective treatment w Techniques: increase loudness and improve intelligibility w Many people with PD have been successfully treated with this program 9
