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

Abstract

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.
