Effectiveness of Lee Silverman Voice Treatment (LSVT)-BIG for Neurological Diseases Other Than Parkinson’s Disease: Mini Review

Background: Lee Silverman Voice Treatment-BIG (LB) was developed for Parkinson’s disease patients to improve patients’ movement amplitude and accuracy through large movements and enhance movements through self-awareness and recalibration. This study aimed to review studies on LB for neurological diseases other than Parkinson’s disease and examine its potential as an intervention tool. Method: The main search databases included Google Scholar, PubMed, and ScienceDirect. ‘Neurological disease’, ‘LSVT-BIG’, ‘Treatment or Rehabilitation’, ‘Intervention’ and ‘Therapy’ were used as search keywords until December 2024, and 8 articles were finally selected. Results: As a result of analyzing 8 studies, there were 4 studies on stroke (all conducted by occupational therapists) and 4 studies on other diseases including 2 studies on progressive supranuclear palsy, 1 study on idiopathic normal pressure hydrocephalus, and 1 study on Huntington’s disease (all conducted by physical therapists). Conclusion: LB had a positive effect on improving physical function and overall motor control in patients with neurological diseases other than Parkinson’s disease, indicating its potential as an intervention tool. In the future, studies that have high-level evidence-based study designs and complement small sample sizes are needed to demonstrate the effectiveness of LB.
