The sample will be 60 women having chronic musculoskeletal pain (we will enroll up to 75 persons to account for attrition and screen failures but require the usable data of only 60 women). Based on enrollment rates for our previous study, and given our expanded catchment area, we expect to enroll 60 persons within approximately 14 months and to complete the experimental phase of the study within approximately 17 months. The follow-up phase of the study will continue, for as long as participants agree to be followed for up to 10 years.
