A Study of Muscle, Mobility and Aging (SOMMA)

What we are studying

The purpose of this research study is to better understand what makes it more difficult to walk as we age. Mobility is critical for functional independence and lack of mobility can lead to increased hospitalizations, illness, disease, and higher health care costs. This study will evaluate the properties of your muscle by looking at MRI images, performing physical ability tests, and by sampling a small piece of muscle to see what changes in the body may lead to changes in your mobility over the course of the study.
