Use of Occupation-Based Measures in LSVT BIG Research: A Case Study.

Parkinson's disease (PD) is a neurodegenerative disorder that results in a variety of motor and nonmotor symptoms that impact occupational performance. To our knowledge, no study has investigated the effect of LSVT BIG using occupational performance outcome measures. The objective of this study was to determine the effects of LSVT BIG on occupational performance with an individual with PD. The participant, a 73-year-old retired female with mild PD, completed the LSVT BIG program. Researchers measured changes in occupational performance using the Canadian Occupational Performance Measure (COPM) and the Performance Assessment of Self-Care Skills (PASS). Results indicated improved client perceptions of occupational performance and satisfaction on the COPM and improved independence and adequacy on the PASS. Despite the positive findings of this study that support the use occupational performance measures to evaluate change within LSVT BIG literature, future research should be conducted to determine causality of identified occupational performance improvements and time course of improvements.

Lee Silverman Voice Treatment BIG® for a Person With Stroke.

The extant literature suggests the Lee Silverman Voice Treatment BIG® (LSVT BIG) program is an effective intervention for persons with Parkinson's disease; however, no literature or research on the use of this program as an intervention for persons with stroke exists. We examined the effects of the LSVT BIG program for a 52-yr-old community-dwelling woman with mild to moderate upper extremity hemiparesis 2 yr after a stroke and the feasibility of delivering the home exercise component of the program in a game-based format. We made measurements at pretest, posttest, and 6-wk follow-up. The participant demonstrated self-reported improvements in occupational performance and satisfaction and large improvements in upper extremity motor function. The next step in this research is to deliver LSVT BIG and a home game-based program with a larger, more diverse population of persons with chronic stroke to further determine the effectiveness and appropriateness of this intervention.
