Evaluating Dancing With Parkinson's: Reflections from the perspective of a community organization

Using theory knitting to conceptualize social phenomena in the design and evaluation of dance programs for people living with Parkinson's disease

Dance programs for people living with Parkinson's disease (PwPD) offer participants an opportunity to exercise, engage in artistic self-expression, and form new relationships. While it is understood that the social dimension of dance programs for PwPD contributes to dancer satisfaction and program sustainability, the social mechanisms instrumental to program success are under-examined. Engaging with theory from wider disciplines, or "theory knitting" can help program designers and evaluators examine the mechanisms and contextual factors that make classes socially meaningful with greater detail and specificity. This study identified and examined three theoretical frameworks that program planners and evaluators could use to conceptualize social engagement in dance for PwPD contexts and inform practice. Each theory was assessed for fit using the T-CaST theory comparison and selection tool developed by Birken et al. (2018). As an example, we used anthropologist Victor Turner's (1970; 1977) theory of liminality and communitas to identify five key areas for fostering a sense of social connection in dance for PwPD contexts: (1) selecting a meaningful dance space (2) creating a joyous atmosphere (3) marking entrance into the liminal time and space with rituals (4) embodying liminality and anti-structure and (5) inverting power relations and embracing fluid roles.

Towards an evolutionary approach to learning from assumptions: Lessons from the evaluation of Dancing with Parkinson's

This paper highlights how learnings from exploring assumptions can be strengthened by taking an evolutionary approach to theory building and analysis. We discuss theory-driven evaluation applied to a community-based intervention implemented by Dancing With Parkinson's in Toronto, Canada, targeting Parkinson's disease (PD), a neurodegenerative condition affecting movement. A major gap in the literature is understanding the mechanisms by which dance might make a difference in the daily lives of people living with PD. This study was an early exploratory evaluation to better understand mechanisms and short-term outcomes. Conventional thinking generally favors "permanent" over "transitory" changes, and "long-term" over "short-term" effects. Yet, for people living with degenerative conditions (and also people experiencing chronic pain and other chronic symptoms), transitory and short-term changes may be highly valued and welcomed relief. In order to study and link multiple longitudinal events to explore key linkages in the theory of change, we piloted the use of diaries, with brief entries filled out daily by participants. The aim was to better understand the short-term experiences of participants using their daily routines as a means of learning about potential mechanisms, what matters to participants, and to see if small effects could be observed on days when participants danced versus days when they did not dance and also longitudinally over several months. Our initial theoretical stance began with a view of dance as exercise and the well-established benefits of exercise; yet, we explored through the diary data collected, as well as client interviews and literature review, potential other mechanisms of dancing (such as group interaction, touch, stimulation by the music, and esthetics including "feeling lovely"). This paper does not develop a full, comprehensive theory of dance but moves towards a more comprehensive view that locates dance within the routine activities of participants' daily lives. We argue that given the challenges of evaluating complex interventions comprising multiple, interacting components, there is a need for an evolutionary learning process to understand heterogeneities in mechanisms -- what works for whom -- when faced with knowledge incompleteness in the theory of change.

Can Samba and Forró Brazilian rhythmic dance be more effective than walking in improving functional mobility and spatiotemporal gait parameters in patients with Parkinson's disease?

Background

Parkinson’s disease (PD) causes motor and nonmotor disorders in patients. Unlike aerobic training, potential adaptations from the practice of dance are less understood in PD, particularly compared with better known exercise modes. This study aimed to verify and compare the effects of a Brazilian dance program, inspired by Samba and Forrró rhythms, and a walking program on functional mobility and spatiotemporal gait parameters in patients with PD.

Methods

Eighteen participants with PD were divided into a dance group (DG) and a walking group (WG) and were assessed before and after an intervention period of 24 1-h sessions, performed twice per week for 12 weeks. The timed-up-and-go test (TUG) and walking kinematics at self-selected speed (SSS) and fast speed (FS) were determined. The generalized estimating equation method was used to compare the DG and WG pre- and post-intervention and to evaluate the group*time interaction (α <  0.05).

Results

Both groups demonstrated a significant improvement in TUG test at SSS (p = 0.02; effect size [ES] = 0.42) and FS (p = 0.02; ES = 0.24). In general, spatiotemporal parameters remained unchanged, except at SSS, in which the DG increased the stride frequency (p = 0.011; ES = 0.72). At FS, the swing time demonstrated a significant group*time interaction (p <  0.001; ES = 1.10), in which the two groups exhibited different behaviors: DG decreased (p = 0.015) and WG increased (p = 0.012).

Conclusions

Functional mobility improved similarly in both groups. The results suggest that a 12-week program of Brazilian dance was sufficient to produce improvements in functional mobility and gait in individuals with PD.
