Summary

Background: Parkinson's disease affects up to 3% of persons over the age of 65. Lower urinary tract symptoms are a frequent cause of diminished quality of life in elderly persons and occur in up to 40% of persons with Parkinson's disease. While the exact mechanisms have not been determined, detrusor hyperactivity (hyperactivity of the bladder muscle) leading to symptoms of overactive bladder and urge incontinence is common. Behavioral and exercise-based therapies have relatively no side effects and have been shown to be an effective treatment for urge symptoms of overactive bladder in the aged population. Hypothesis and Specific Aims: Behavioral therapy using pelvic floor muscle exercises will result in a 50% decrease in the number of incontinence episodes in elderly persons (age \> 50) with Parkinson's disease. The specific aims for this pilot study include the following: 1. Complete a course of behavioral therapy using computer-assisted biofeedback in 20 subjects with UI associated with PD and determine how many potential subjects need to be screened and enrolled to achieve this sample size. 2. Determine the proportion of these patients who achieve a 50% or greater reduction in UI episodes. 3. Examine whether responsiveness is associated with characteristics of the Parkinson's disease, in particular disease severity as measured by the Unified Parkinson's Disease Rating Scale (UPDRS). 4. Assess the effectiveness of behavioral therapy without the use of computer-assisted biofeedback instruction in 10 additional subjects with PD and UI. Methods: The first 20 participants will be enrolled in an 8-week treatment trial of behavioral therapies and pelvic floor muscle exercises with computer-assisted biofeedback. Ten additional participants will be enrolled in the 8-week treatment trial of behavioral therapy, but will not have computer-assisted biofeedback. Voiding diaries as well as urinary symptom and quality of life questionnaires will be used to assess response. If persons with Parkinson's disease can complete the treatment trial and achieve a reduction in episodes of urinary incontinence with behavioral techniques this would lay the foundation for a larger, placebo-controlled trial. Assessment of responsiveness associated with severity of Parkinson's disease would also provide important information about the utility of this treatment strategy.

Conditions

• Urinary Incontinence
• Parkinson's Disease

Interventions

Type	Name	Description
OTHER	Exercise-based behavioral therapy	Participants will be taught pelvic floor muscle exercises as well as urge suppression strategies to overcome the urge to void. In the first 20 participants, computer-assisted biofeedback will also be utilized to help participants identify the pelvic floor muscles and contract and relax these muscles while keeping the abdominal muscles relaxed
