Sensory Attention Focused Exercise in Parkinson's Disease

November 22, 2010 updated by: Sun Life Financial Movement Disorders Research and Rehabilitation Centre

Sensory Attention Focused Exercise in Parkinson's Disease: A Randomized Double-Crossover Trial.

The purpose of this study is 1.) to determine if sensory attention focused exercise is an effective management strategy for Parkinson's disease, and 2.) to identify if the benefits are a result of strength gains.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Currently, there is no cure for Parkinson's disease (PD) and although medication offers symptom reduction, there are many negative side effects associated with medication use. Thus, there has been an increased emphasis on exercise interventions for symptom reduction. Recent research has shown that both sensory attention focused exercise (SAFEx) and strength training interventions improved disease severity more so than other exercise interventions (such as aerobic, aquatic and no exercise). Upon closer examination, SAFEx showed further symptom improvements than the strength training program. Thus exists the need to further examine SAFEx using a standardized protocol - a single-blind randomized double-crossover trial - that has been used sparingly in exercise interventions. In addition, the 30-second chair stand has been implemented into the testing protocol, as it has been shown to be a reliable measurement of functional strength for older adults. This test was implemented in order to identify the functional strength gains, if any, that are associated with SAFEx. It is hypothesized that the SAFEx intervention will improve disease symptoms in PD, and that the results will not be due to strength gains.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
