All participants completed 8 weeks of the dance-based exercise program, with an average participation rate of 92.5% (varying from 13 to 16 sessions out of a possible 16). All but one of the participants were able to progressively increase the intensity of training; one of the participants had to restrain intensity to a mean of 44% HR reserve due to effort hypertension. Three of the participants changed medications during the intervention period, one of who experienced serious side effects (nausea, vomiting, bleeding) due to new medication usage. The latter participant also did not complete the post-intervention graded exercise test secondary to a very low serum hemoglobin level (86 g/l). Another participant did not complete the post-intervention treadmill and locomotor tests due to a ruptured Baker's cyst in the right lower limb. None of the participants displayed a worsening of disease state as a result of the intervention. A significant decrease in joint swelling was observed after the training program, as well as a significant improvement in 6-minute and laboratory gait test scores. In addition, significant increases in range of motion were noted in areas of the hip and knee joints. No significant change was observed in joint pain intensity, amplitude of motion, and score on the 50-foot test of walking time over the course of the intervention period.
