Importance: People with Parkinson's disease (PD) experience motor and functional impairment that can negatively affect daily living and participation.
Objective: To examine the occupational performance and hand function outcomes of people with PD who participated in a Lee Silverman Voice Treatment (LSVT) BIG® program.
Design: Retrospective record review.
Setting: Outcomes were extracted from patient charts at a hospital outpatient clinic.
Participants: Sixty-six clinic outpatients with PD who completed the LSVT BIG program.
Intervention: An occupational therapist and a physical therapist who were certified in LSVT BIG administration delivered the 16-session LSVT BIG program. Outcomes and Measures: The Canadian Occupational Performance Measure (COPM), grip strength, and Minnesota Manual Dexterity Test (MMDT) were administered before and after participation in LSVT BIG training.
Results: For participant-identified COPM goals, pre-post changes were significant, ranging from 3 to 6 points for performance and satisfaction (p < .001). Grip strength in both hands showed significant gains; median scores for the right hand increased from 55.0 lb (interquartile range [IQR] 41.0, 70.0) to 64.0 lb (IQR 46.0, 80.0; p < .001) and for the left hand from 52.0 lb (IQR 39.0, 64.0) to 63.0 lb (IQR 44.5, 79.5; p < .001). MMDT median scores for right to left also significantly improved, from 124.0 s (IQR 113.0, 181.0) to 119.5 s (IQR 105.5, 163.5; p = .014).
Conclusions And Relevance: Participation in the LSVT BIG program can improve perceived occupational performance and satisfaction and produce gains in hand strength and dexterity for people with PD. What This Article Adds: This study is the first retrospective review of data on occupational performance and hand function outcomes after participation in the LSVT BIG program. The findings of beneficial outcomes support the use of LSVT BIG in occupational therapy services to increase functional abilities among people with PD.

Practitioner perspectives on the implementation of the Lee Silverman Voice Treatment BIG® program.

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.
