EMBr Wave for the Reduction of Hot Flashes in Women With a History of Breast Cancer

PRIMARY OBJECTIVE: I. To evaluate the feasibility of using EMBr Wave technology in women with a history of breast cancer who are experiencing bothersome hot flashes. SECONDARY OBJECTIVES: I. To evaluate the preliminary efficacy of EMBr Wave in reducing hot flash severity and frequency in women with a history of breast cancer. II. To identify in what ways EMBr Wave has the greatest potential efficacy, such as reduction in vasomotor symptoms (VMS) severity, frequency, duration, sense of control, or self-esteem. III. To estimate effect sizes to inform power calculations for a future phase III trial. OUTLINE: Patients are randomized to 1 of 2 arms. ARM A: Patients utilize the EMBr Wave device for 4 weeks, then crossover to arm B for 4 weeks. ARM B: Patients receive no treatment for 4 weeks, then crossover to arm A for 4 weeks.
