Dance for Parkinson's-The effects on whole body co-ordination during turning around.

OBJECTIVE

To investigate the effects of ballroom and Latin American dancing classes on turning in people with Parkinson's.

DESIGN

This study employed a randomised, controlled, experimental design.

SETTING

Dance classes were performed in a community dance centre in Southern England and all assessments took place a gait laboratory.

PARTICIPANTS

Twenty-seven people with mild-moderate Parkinson's participated.

INTERVENTION

Participants were randomly allocated to receive either 20, 1-h dancing classes over 10 weeks (n=15), or a 'usual care' control group (n=12).

MAIN OUTCOME MEASURE

Twelve, 180° on-the-spot turns to the predicted/un-predicted and preferred/un-preferred direction were analysed for each participant, using 3-dimensional motion analysis before and after the intervention period, alongside clinical measures.

RESULTS

Movement of the head, pelvis, and feet during turning in people with Parkinson's are affected by dancing with tighter coupling of body segments. Significant 4-way interactions between the groups, over time and turn style, with longer latency of the head (p=0.008) and greater rotation in the pelvis (p=0.036), alongside a trend of slower movement of the first (p=0.063) and second (p=0.081) foot in controls were shown, with minimal change in dancers. All interactions were affected by the type of turn. No significant differences were found in the centre of mass displacement, turn time or clinical measures.

CONCLUSION

Those who danced were better able to coordinate their axial and perpendicular segments and surprisingly became more 'en bloc' in their turning behaviour, suggesting this may be a beneficial adaptation, rather than a maladaptive result of Parkinson's, as previously suggested.
