Feasibility of the Lee Silverman Voice Treatment®-BIG Intervention in Stroke

Feasibility of the Lee Silverman Voice Treatment®-BIG Intervention in Stroke

Evaluate feasibility (acceptability, subject recruitment/retention, willingness to be randomized, and adherence rates) of delivering the Lee Silverman Voice Treatment®-BIG (LSVT®BIG) intervention with individuals with chronic stroke. Evaluate preliminary effect of the LSVT®BIG intervention on motor function and occupational performance with individuals with chronic stroke.

Literature suggests the Lee Silverman Voice Treatment®-BIG (LSVT-BIG®) program is an effective intervention for individuals with Parkinson's Disease (Ebersbach et al., 2015); however, no literature or research exists on the use of this program as an intervention for individuals with stroke. Therefore, this project aims to measure the effectiveness of the LSVT®BIG program with one individual with a stroke to determine if LSVT®BIG is a feasible and effective occupational therapy intervention for this population. The LSVT®BIG program is an intensive program with hands-on treatment sessions 4 days per week for 4 weeks. Clients complete home exercises every day that enhance the hands-on treatment and help promote carry-over of skills learned to daily tasks. The investigators have completed two case studies with clients with chronic stroke who demonstrated improved outcomes in upper extremity motor function and occupational performance. The purpose of this study is to test the LSVT®BIG intervention with a larger clinical population and to demonstrate that LSVT®BIG is an effective and feasible treatment option for improvement in occupational performance and upper extremity motor function with individuals with stroke.
