The purpose of this study is to determine whether it might be practical and useful to investigate the effectiveness of yoga classes in relieving joint pain associated with the use of a class of medications known as aromatase inhibitors.
The study uses a single-arm design. All study participants will be assigned to an intervention condition in which they participate in group Iyengar yoga classes for 90 minutes twice per week for 12 weeks (total of 24 classes). Study outcomes are assessed: 1) following recruitment but prior to the first yoga class; and 2) within two weeks post-intervention (follow-up). Additionally, a brief assessment of pain will be conducted four weeks and eight weeks after the start of yoga classes.

Rate of Study Enrollment
Acceptability of the proposed study to potential participants. The study will be considered acceptable if 50% or more of eligible participants agree to participate.
Time frame: 24 months
Rate of Study Completion
Feasibility of the proposed study assessment and intervention methods. The study methods will be considered feasible if 70% or more of consented participants complete both the baseline and follow-up assessments and attend an average of 70% or more of scheduled yoga classes.
Time frame: Up to 24 weeks per participant
Occurrence of Reduced Pain Severity
Potential efficacy of the intervention in relieving AI medication-associated joint pain. The intervention will be considered potentially efficacious in relieving AI medication-associated joint pain if comparisons of pre- and post-intervention means for one or more measures of pain severity yield an effect size \>/= 0.3 consistent with pain reduction.
Time frame: Up to 24 weeks per participant
Occurrence of Relief from Other Side Effects
Potential efficacy of the intervention in relieving other reported side effects of AI medication (i.e., fatigue, hot flashes, sleep problems, and depressive symptoms). The intervention will be considered potentially efficacious in relieving other known side effects if comparisons of pre- and post-intervention means yield an effect size \>/= 0.3 consistent with side effect reduction.
Time frame: Up to 24 weeks per participant
