The purpose of this study is to examine the changes in postural stability in older adults following exposure to a beginning ballet dance technique course. Postural stability will be assessed at baseline and following the intervention using Wii Balance Boards as an affordable alternative to force plates. It is hypothesized that a significantly reduced body sway will be observed in participants following a ballet dance training course over a 10-week period.

Postural stability (balance) is an essential skill across many genres of dance in order to create and maintain specific positions and motions with proper technique. Previously, it has been shown that dance interventions can lead to improvements in postural stability in elderly populations. However, there is limited research examining changes in balance following ballet dance class interventions for older adults.

One-hour ballet classes will be held twice per week in one of the two dance studios at Skidmore College. A dance student will serve as the lead teacher for each dance class session throughout the 10 weeks of ballet classes. Each week the participants will partake in 120 minutes of ballet dance training, starting with warm-up exercises at the barre and then working towards learning combinations in the center. They will learn the basic positions and combinations used in ballet, including: Plié, Tendu, Degagé, Rond de Jambe, Frappé, Chassé, Sauté, Pas de Bourrée, Glissade, and Révérance. Additional ballet movements and patterns may be employed as well. Skidmore students acting as teachers for the ballet classes will receive training packets with all necessary information about the logistics of the class and suggestions on how to be assist during the classes. The packet will discuss appropriate interactions and confidentiality during the class.

To assess postural stability, participants will be asked to stay in a static standing position for trials of 30 seconds while standing on a Wii board in four of the following conditions : 1) bilateral stance with eyes open, 2) bilateral stance with eyes closed, 3) unilateral stance on the right limb 4) unilateral stance on the left limb. Participants will be given a 15 seconds rest period between each trial and will be told they may stop and rest at any moment during the testing process. Data collection will take place at the multipurpose room (Williamson Sports Center), the intramural gym (Williamson Sports Center), or at the Prestwick Chase facility or the Saratoga Senior Center (if requested by an activities director) prior to the start of the ballet classes with post-testing to be completed the week of, or following, the final ballet class. Tests of postural stability will be verbally explained/instructed to create clear expectations for the test and to help decrease any fear or anxiety surrounding the process.
