'Digital Dancing' - "Can you see, what I feel" - An exploration of the physical 'experience' of dance for Parkinson's through 3-dimensional motion analysis.

BACKGROUND: Parkinson's is a common, progressive, neurodegenerative movement disorder of the central nervous system. Research has consistently shown that dancing can have a positive impact on the lives of people living with Parkinson's (PwP). PwP who dance report that current measurement of the effects fails to appreciate the multifactorial presentation of the condition as well as the biopsychosocial potential of dance holistically. AIM: To explore the feasibility of combining measurements of whole-body movement using 3-dimensional motion analysis with the lived experience of dance for PwP, to see if it is possible to 'see (measure)' what PwP say they 'feel (experience)' when dancing, in a 'mind/body approach' METHOD: : Thirteen PwP and ten Carers took part in three community delivered 'Parkinson's Dance Science' classes followed by focus group reflection. Three PwP wore a 3-dimensional, motion capture suit that recorded whole-body movement throughout the class and were interviewed about their experiences. Data were analysed using a 'Convergent Parallel' mixed methods design, mapping participant's experiences and reflections over six biomechanical movement variables. RESULTS: Quantitative results indicate that it is possible to use 3-dimensional motion capture to measure biomechanical change during and following dance in PwP but the amount and direction of change was different for each participant. Qualitative results showed PwP felt the methods were feasible and reported a positive immediate and long-term effect of dance in a complete 'mind/body experience'. The sample size did not permit further analysis, but areas of development suggest it may not be the change in physical ability that is important, but more the perception of change following dance that is unique to each individual. Thus single measures of the effects of dance for PwP are likely to be insufficient when trying to understand the effect holistically. CONCLUSION: A 'Convergent Parallel' mixed methods research design, mapping the experience of dance for PwP ('what I feel') and their peers against biomechanical change ('what you see') following dance is feasible. Further research is required to develop the method with a larger sample to truly begin to understand the potential and effects of dance for PwP.

It takes two: the influence of dance partners on the perceived enjoyment and benefits during participation in partnered ballroom dance classes for people with Parkinson's.

PURPOSE: To explore the views of people with Parkinson's and their dance partners on the influence and issues surrounding dancing with an able-bodied dance partner during partnered ball room dance classes. METHODS: In depth, semi-structured interviews explored purposively selected participants' experiences and views about dance classes. Fourteen people with Parkinson's and their dance partners (six spouses, two friends/relatives, five volunteers) were interviewed within a month of completing the 10-week dance class program. Data were analyzed thematically. RESULTS: Generally, those partnered with a spouse or an experienced dancer, or when dance couples were able to develop good rapport, gained greater enjoyment and sense of achievement from dance classes in comparison to couples who did not enjoy dancing together or had clashing approaches to dance. Managing and negotiating who would "lead" in a dance was challenging for dance couples particularly among male people with Parkinson's. CONCLUSIONS: People with Parkinson's experience of the dance classes were influenced by the relationship and compatibility with their dance partner. Dance partnerships may impact on recruitment, enjoyment, outcome and continued participation in dance classes. Potential effects of partnerships should be analyzed and reported in studies evaluating the outcomes of dance classes. Implications for rehabilitation We recommend that health professionals consider involving spouses in Parkinson's dance classes as this may improve recruitment, adherence, enjoyment and overall outcome of the dance classes. If volunteers are needed, aim to recruit those who already have good dancing ability, convey a love of dancing and have the sensitivity and social skills to interact positively with the person with Parkinson's. Consider dance partnership issues when advertising and promoting dance classes. Address partnership issues through open communication and by changing partners if the dance partnership is not working well.

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.
