Abstract

AbstractBackgroundLee Silverman voice treatment (LSVT) BIG is an exercise program developed for patients with Parkinson's disease (PwPD), consisting of sets of exercises performed for 4 consecutive days a week for 4 weeks. However, the standard protocol suggests a treatment frequency difficult to follow for most patients who have difficulties reaching rehabilitation clinics. Our aim was to compare the standard LSVT BIG protocol with a modified LSVT (m‐LSVT) BIG protocol (twice a week in the clinic for 4 weeks and twice a week at home for 4 weeks).MethodsIn this randomized controlled trial, 16 PwPD (aged 18–80 years, Hoehn and Yahr stages I–III) were recruited into two groups. The LSVT group received standard LSVT BIG training (four times per week for 4 weeks at the clinic). The other group was given m‐LSVT BIG exercises, but unlike the LSVT group, the m‐LSVT group exercised twice a week at the clinic and twice a week at home for 4 weeks. The Berg Balance Scale was used to assess functional balance. Biodex Balance System was used to assess laboratory balance measures. Timed Up and Go test and G‐Walk sensor system were used to assess functional mobility and spatiotemporal gait analysis.ResultsSignificant group‐by‐time interactions on the eyes open‐firm surface score of the modified clinical test of sensory integration of balance (F = 10.138, p = .007) and gait cycle symmetry index (F = 10.470, p = .010) were found to be in favor of the LSVT group. Additionally, post hoc analyses revealed that both groups significantly improved postural stability, gait speed, motor symptoms, and functional mobility (p < .05).ConclusionThe results revealed the beneficial effects of the modified protocol on balance and gait in PwPD, as well as the superiority of the standard LSVT BIG protocol. The m‐LSVT BIG protocol may be an effective intervention method, especially for PwPD who have difficulty adapting to the treatment frequency of the standard protocol.
