Effect of Low Intensity Vibration (LIV) on Aromatase Inhibitor- Induced Musculoskeletal Dysfunction in Early Stage Breast Cancer Survivors
United States72 participantsStarted 2019-10-02
Plain-language summary
The purpose of this study is to compare the effect of low intensity vibration (LIV) delivered for 10 minutes twice daily for 12 months on skeletal muscle function, in terms of energetic capacity measured by power generation on a stationary bicycle, among patients with early stage breast cancer planned to initiate aromatase inhibitor therapy who do not currently participate in regular exercise, compared to a wait- listed control.

Inclusion criteria
. Age ≥ 18 years
. Diagnosis of DCIS or stage I, II, or III breast cancer 3 Planned to initiate an AI
. Post- menopausal defined as ≥ 60 years of age, prior bilateral oophorectomy, or age over 50 and absence of any menstrual periods in the last 12 months, or FSH and estradiol in the menopausal range
. Premenopausal patients receiving chemical ovarian suppression are allowed
. Prior aromatase inhibitor use (if this is a second primary, for example) is allowed as long as it has been more than 12 months
. Prior tamoxifen is allowed if switching to an aromatase inhibitor, as long as it has been 28 days between last tamoxifen dose and the baseline procedures (per the half-life of tamoxifen)

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
