The benefits of group occupational therapy for patients with Parkinson's disease.
The medical treatment of idiopathic Parkinson's disease has improved the quality of life and increased survival of patients with Parkinson's disease. However, as the illness progresses, impairments in daily living activities occur. A clinical trial for a group rehabilitation program was initiated to maintain the functional status of these patients. The research protocol consisted of a pretreatment evaluation, random assignment to experimental or control groups, and posttreatment evaluations after therapy, at 6 months and at 1 year. The results showed that the subjects of the treated experimental group maintained their functional status after 1 year, demonstrated a significant decrease of bradykinesia, and perceived a significant improvement in their psychological well-being. This study confirms the value of an occupational therapy group approach and its benefits to the functional independence, to the improvement of physical and motor symptoms, and to the quality of life of persons with Parkinson's disease.
Considering the significant methodological flaws in the studies, the small number of patients examined, and the possibility of publication bias, there is insufficient evidence to support or refute the efficacy of occupational therapy in Parkinson's disease. There is now a consensus as to UK current and best practice in occupational therapy when treating people with Parkinson's disease. We now require large well designed placebo-controlled RCTs to demonstrate occupational therapy's effectiveness in Parkinson's disease. Outcome measures with particular relevance to patients, carers, occupational therapists and physicians should be chosen and the patients monitored for at least six months to determine the duration of benefit. The trials should be reported using CONSORT guidelines.
