Randomized controlled trial of the Alexander Technique for idiopathic Parkinson's disease

Objective: To determine whether the Alexander Technique, alongside normal treatment, is of benefit to people disabled by idiopathic Parkinson's disease. Design: A randomized controlled trial with three groups, one receiving lessons in the Alexander Technique, another receiving massage and one with no additional intervention. Measures were taken pre and post-intervention, and at follow-up, six months later. Setting: The Polyclinic at the University of Westminster, Central London. Subjects: Ninety-three people with clinically confirmed idiopathic Parkinson's disease. Interventions: The Alexander Technique group received 24 lessons in the Alexander Technique and the massage group received 24 sessions of massage. Main outcome measures: The main outcome measures were the Self-assessment Parkinson's Disease Disability Scale (SPDDS) at best and at worst times of day. Secondary measures included the Beck Depression Inventory and an Attitudes to Self Scale. Results: The Alexander Technique group improved compared with the no additional intervention group, pre-intervention to post-intervention, both on the SPDDS at best, p = 0.04 (confidence interval (CI) –6.4 to 0.0) and on the SPDDS at worst, p = 0.01 (CI –11.5 to –1.8). The comparative improvement was maintained at six-month follow-up: on the SPDDS at best, p = 0.04 (CI –7.7 to 0.0) and on the SPDDS at worst, p = 0.01 (CI –11.8 to –0.9). The Alexander Technique group was comparatively less depressed post-intervention, p = 0.03 (CI –3.8 to 0.0) on the Beck Depression Inventory, and at six-month follow-up had improved on the Attitudes to Self Scale, p = 0.04 (CI –13.9 to 0.0). Conclusions: There is evidence that lessons in the Alexander Technique are likely to lead to sustained benefit for people with Parkinson's disease.
