Parkinson's is a progressive neurodegenerative disease. Common symptoms of Parkinson's are resting tremor, bradykinesia, rigidity, mask face, and difficulties with gait. Gait difficulties include short and shuffling steps, festination and/or freezing of gait, difficulty turning or walking backward, and impaired ability to perform dual tasks when walking.  Individuals with Parkinson's are also at an increased risk of falls.
Medical treatments for Parkinson's, including medications, do not fully address gait and balance issues and so exercise has become an important part of treatment. Four key areas of focus when designing exercise programs for Parkinson's as recommended by Keus et al. are:
- Cueing strategies to improve gait,
- Cognitive movement strategies to improve transfers,
- Exercises to improve balance, and
- Training of joint mobility and muscle power to improve physical capacity.
- The use of music to accompany dance movement can act as an external cue to facilitate movement.
- The use of specific movement strategies when teaching dance steps.
- The need to control dynamic balance and respond to perturbations when interacting with other participants facilitates balance exercises.
- Dance helps enhance strength and flexibility. It may also improve cardiovascular functioning if done at a sufficient intensity.
The first study that examined the potential benefits of dance for individuals with Parkinson's was completed in the late 1980s by Westbrook et al.  comparing dance/movement therapy with a traditional exercise program over a 6-week period of time. Later in 2001, Olie Westheimer, the Founder and Executive Director of the Brooklyn Parkinson Group teamed up with the Mark Morris Dance Group, a modern dance company that had recently opened a dance centre in Brooklyn. Two dancers from the Mark Morris Dance Group, John Heginbotham and David Leventhal, started leading monthly classes, offered free of charge to individuals with PD. In 2004 the Mark Morris Dance Group began leading their classes in cities where the company was touring. Mark Morris Dance Group subsequently developed a training program for dance teachers and began offering free demo classes and teacher training workshops. The original Brooklyn program now serves as a model for Parkinson's dance classes in 30 U.S. states and ten countries: Australia, Canada, England, Germany, Holland, India, Israel, Italy, Mexico, and Scotland.
Other studies have focused on studying the benefits of partnered dance forms, with an emphasis on Argentine tango in the literature. These studies demonstrated that not only was functional capacity improved but that participants were more likely to continue with a dance class than a traditional exercise program.
The cognitive and functional benefits of dance in people with Parkinson's are continuously researched, however, it is important to note the additional benefit of creating engaging and active Parkinson's communities where none previously existed.
Potential Benefits of Dance in Individuals with Parkinson's
Dance is shown to benefit individuals with Parkinson's by enhancing motor function through stretching, stepping and balance. Individuals who participated in a dance intervention ranging from 90 minutes of dance per week for 8 weeks, to 2 hours, two times per week for 2 years, showed improvements in various outcome measures, notably the Berg Balance Scale, when compared to a regular exercise group. The motor improvements could be due to repetition, direction change, and step sequencing that are inherent in dance and transfer into effective, regular gait patterns. Furthermore, basal ganglia may be activated during rhythmic movements and enhanced by the auditory cues in the music accompanying dance.
Dos Santos Delabary et al in a systematic review, that included 159 patients has found that dance leads to significant improvements on Unified Parkinson's Rating Scale III and decreased Timed Up and Go Test in comparison with other types of exercise. It was also significant improvements in motor scores in dance practice compared to the absence of intervention.
The changing visual and auditory stimuli, unique to dance, facilitate cognitive improvements when compared to regular exercise programs for people with Parkinson's. A dance class creates an environment where individuals must control continuously changing patterns of movement to match the instructor. Dance has been shown to reduce the time taken to correctly complete the MRT (Mental Rotation Task) as dance aids in imagery formation and judgement. The attention required to anticipate movements, and respond to changes in music or instruction is unique to dance and can enhance the activity of the basal ganglia loops and frontal lobes. This is supported by greater improvement in FAB (frontal assessment battery). When compared to traditional rehabilitation (balance exercises, gait training) there were moderate improvements in cognitive test scores at the 8-week follow up, supporting dance therapy as being able to impact higher cortical functions in the long term.
Mental Health Benefits
Mental health benefits for individuals with Parkinson's are exclusive to dance when compared to control and regular exercise treatment. The improvement shown in mood, motivation and enjoyment can be related to feelings of unity. There are improved AP (apathy scale) and SDS (self-rating depression scale) scores after dance intervention in people with Parkinson's. It has been suggested that dance therapy can decrease fear of falling through practicing position changes in a controlled environment. Overall, health-related quality of life and emotional well-being has been increased through dance for people living with Parkinson's.
When compared to regular exercise and control groups, dance for Parkinson's yields greater gains in UPDRS (Unified Parkinson's Rating Scale). Please note that research is required to determine the optimal types of dance and parameters (i.e. frequency, intensity, duration) of dance to address specific motor impairments in people with Parkinson's. Personal, cultural, and social preferences need to be considered to improve adherence to the treatment program.
Types of Dance and Parkinson's Outcomes
Style of Dance and Effects on Parkinson's
The style of dance most prominently researched in people with Parkinson's is the tango. Tango is thought to target major functional impairments in people with Parkinson's, such as walking backward, starting and stopping gait, turning, and changing tempo. In a comparison of Argentine tango to American ballroom (waltz and foxtrot), both groups had significant improvement in balance, locomotion, and motor control. The benefits were greater in the tango group which also showed significant improvement in freezing of gait. In both a meta-analysis and systematic review, investigation into comparing different forms of dance to determine whether tango really does provide more benefits is recommended.
Below is a list of benefits specific to particular dance styles:
- Irish step dancing significantly improved freezing in people with Parkinson's, while tango did not significantly improve freezing (as measured using the Freezing of Gait Questionnaire).
- Turkish Folkloristic dance improved muscle strength and endurance (as measured using the 5 Times Sit to Stand).
- Tango, waltz, and foxtrot improved scores in the 6 Minute Walk Test.
- Balance improvement is consistent in the literature, regardless of dance type.
Partnered Versus Non-Partnered Dance's Effect on Parkinson's
In a study of partnered versus non-partnered tango interventions for people with Parkinson's, both groups improved in cadence, Berg Balance Scale scores, and comfortable and fast-as-possible walking speed. Patients in the partnered class reported having more motivation to continue with the program and more enjoyment partaking in the class. To date, research comparing partnered to non-partnered dance is limited.
