The technique called Lee Silverman Voice Treatment (LSVT)-LOUD has
previously been used to improve voice quality in people with Parkinson's disease.
The objective of this study was to assess the effectiveness of an alternate
intervention, LSVT-BIG (signifying big movements), to improve functional
mobility. DESIGN: Systematic review with meta-analysis of randomized trials. DATA
SOURCES: Medline, Embase, CINAHL, AgeLine, Scopus and Cochrane Library were
searched from inception to September 2017 using multiple search terms related to
Parkinson's disease and LSVT-BIG. REVIEW METHOD: Two researchers searched the
literature for studies of the LSVT-BIG intervention of 16 sessions, delivered by
a certified instructor over four weeks, to any other intervention. Outcomes
related to functional ability were included. Study quality was appraised using
the Cochrane Risk of Bias tool. RESULTS: Four studies were included, reporting on
three randomized trials of 84 participants with mild Parkinson's disease.
Compared to physiotherapy exercises, or a shorter training protocol, there was a
significant improvement in motor function assessed with the Unified Parkinson's
Disease Rating Scale part III (mean difference = -3.20, 95% confidence interval =
-5.18 to -1.23) and a trend towards faster Timed Up and Go performance (mean
difference = -0.47, 95% confidence interval = -0.99 to 0.06) and 10-metre walk
test (mean difference = -0.53, 95% confidence interval = -1.07 to 0.01). CONCLUSION: Compared to shorter format LSVT-BIG or general exercise, LSVT-BIG was
more effective at improving motor function. This provides preliminary, moderate
quality evidence that amplitude-oriented training is effective in reducing motor
impairments for people with mild Parkinson's disease.
