Background And Purpose: LSVT BIG therapy may improve motor function and gait in those with early Parkinson disease (PD), but its impact on postural control for those with moderate PD has not been investigated. The purpose of this case series is to describe the impact of LSVT BIG therapy on postural control and gait in three individuals with moderate PD.
Intervention: Three individuals with moderate PD, classified as stage 3 on the Hoehn and Yahr Scale, participated in the LSVT BIG therapy program. Intervention included 16-18 individual physical therapy sessions, provided within 4 weeks, focused on increasing amplitude of movement and a daily home exercise program. Outcomes, including balance, gait, dual-task performance, quality of life, and balance confidence, were examined after program completion, 1- and 4-months later.
Outcomes: Clinically meaningful improvements in balance and gait, including performance under dual-task conditions, were achieved by all patients and many of these improvements were maintained up to 4 months later. Changes in quality of life were not observed during the length of the intervention.
Conclusion: LSVT BIG therapy may improve postural control, gait, and dual-task performance, and therefore reduce fall risk for individuals with moderate PD.

Background: The Lee Silverman Voice Treatment BIG® (LSVT BIG®) intervention, originally designed for the patients with Parkinson's disease, is a high amplitude, high repetition therapy protocol that encourages bigger, more quality movements. The purpose of this study was to understand practitioner utilization and perspectives of the LSVT BIG® intervention as there is no published work in this area.
Methods: An electronic survey with optional debriefings was distributed to LSVT BIG® certified practitioners via the Facebook page run by parent company, LSVT Global Inc.

Background: Physical exercise is effective in managing Parkinson's disease (PD), but the relative benefit of different exercise types remains unclear.
Objectives: To compare the effects of different types of physical exercise in adults with PD on the severity of motor signs, quality of life (QoL), and the occurrence of adverse events, and to generate a clinically meaningful treatment ranking using network meta-analyses (NMAs).
Search Methods: An experienced information specialist performed a systematic search for relevant articles in CENTRAL, MEDLINE, Embase, and five other databases to 17 May 2021.
The effects of standard and modified LSVT BIG therapy protocols on balance and gait in Parkinson's disease: A randomized controlled trial.

Background: Lee 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).

Introduction: The purpose of this study was to evaluate change in motor function, gait speed, dynamic balance, balance confidence, and quality of life (QoL) in nine participants with Parkinson's disease (PwPD) completing Lee Silverman Voice Treatment BIG (LSVT-BIG), an external cueing and task-based intervention. Although supported as an efficacious treatment in PwPD, there is limited research examining clinically meaningful change in outcome measures related to external cueing and task-based interventions.
Materials And Methods: This was a case series of nine PwPD (age range 64-76 years, 55% male) who completed the LSVT-BIG protocol.

Background: Parkinson's disease (PD) is a common neurodegenerative illness associated with motor symptoms.
Aim: The aim of study was to compare the effects of synchronous telerehabilitation-based Lee Silverman Voice Treatment® BIG (LSVT® BIG) protocol and progressive structured mobility training in patients with Parkinson's disease (PD).
Methods: Thirty-two patients diagnosed with PD (aged 40-72 years, Hoehn-Yahr stage 1-3) were randomly allocated into LSVT® BIG (Group 1) and Progressive Structured Mobility Training (Group 2) groups.
