Description:
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.

Purpose
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.
Detailed Description
This is a randomized phase II, two arm, single-center study designed to compare the effect of
LIV versus wait-list control on the clinical parameter of energetic capacity, or power
generation, in patients with early stage breast cancer receiving aromatase inhibitor therapy
over a 12-month period. The primary endpoint is the 12-month change in energetic capacity
since baseline.
Primary Objective To compare the effect of 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
Secondary Objectives
1. To compare the effect of LIV versus wait-listed control upon muscle contractile
properties including peak power, fatigue resistance, and recovery, measured by
isokinetic knee extension
2. To compare the effect of LIV versus wait- listed control upon body composition (lean
mass, total adiposity) measured by DXA scan
3. To compare the effect of LIV versus wait- listed control upon bone mineral density (T
score) measured by DXA scan
4. To compare the effect of LIV versus wait- listed control upon muscle adipose
infiltration measured by muscle density on peripheral quantitative CT imaging of the
proximal and distal tibia and radius
5. To compare the effect of LIV versus wait-listed control on trabecular and cortical
volumetric bone mineral density by high resolution peripheral quantitative CT of the
distal and diaphyseal tibia and radius
6. To compare the effect of LIV versus wait- listed control on serologic markers of bone
turnover, including TGF-beta and NTX
7. To compare the effect of LIV versus wait- listed controls upon patient reported outcome
measures of fatigue (measured by the Basic Fatigue Inventory), muscle ache, and joint
pain (measured by PRO-CTCAE)
8. To describe the feasibility of LIV in this patient population, defined by patient
compliance and follow up with the intervention
