Abstract
Our objectives to examine whether Strolll - an individually-tailored gamified augmented-reality gait-and-balance therapy for people with Parkinson's disease - meets intensity thresholds to also qualify as aerobic exercise were to: 1) quantify exercise intensity of a representative 30 active-minutes Strolll gait-and-balance therapy session at home and 2) examine if Strolll exercise settings (type of gamified exercise and its difficulty level and duration) could influence exercise intensity. Within-subject experimental design. Home environment. A convenience sample of fifteen individuals with Parkinson's Disease (Hoehn & Yahr stages 1-3, 12/3 males/females, 46-84 years of age) familiar with Strolll exercises. On separate days, participants completed a representative 30 active-minutes gait-and-balance therapy session at home and performed the five different gait-and-balance exercise types at various difficulty levels and durations. Exercise intensity was expressed as percentage heart rate reserve (%HRR) and Rate of Perceived Exertion (RPE). The 30 active-minutes gait-and-balance therapy session reached moderate-to-vigorous exercise-intensity levels for 9 (%HRR) and 14 (RPE) of the 15 participants. Exercise intensity varied over the five gamified exercise types. Varying the level and duration of exercise types had a smaller influence on exercise intensity. Strolll, designed to target aspects of gait, balance and fall risk, showed potential to be applied as a moderate-to-vigorous exercise-intensity program (meeting intensity levels for most participants). Exercise settings to (further) influence exercise intensity levels of augmented-reality exercises were identified. With the proper exercise settings prescribed, Strolll may also qualify as moderate-or-higher intensity aerobic exercise, creating opportunities for multimodal therapy facilitating multiple rehabilitation targets simultaneously in the future.
