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.
