Study of Genetic Muscle and Bone Disorders Using Diffuse Optical Spectroscopy in Adults 18 and Older

What this Trial Is About

Researchers are exploring the genetic causes of muscle diseases, especially those occurring alongside inherited bone disorders. This observational study aims to better understand how muscle and bone diseases that run in families affect tissue function and metabolism over time. The research uses a non-invasive technology called Diffuse Optical Spectroscopy to study these tissue changes. Diffuse Optical Spectroscopy is a quick and painless device developed at the University of California, Irvine. It measures concentrations of blood, water, and fats in tissues by shining infrared light on the skin using a probe placed on areas such as the calf, bicep, or head. The probe is held in place gently by hand or secured with medically approved wraps or tapes, leaving small marks on the skin to ensure consistent placement during repeated measurements. The technique involves no radiation and may include placing a detector directly on the skin in some cases. Participants will have the spectroscopy probe applied to specific body areas to gather data on tissue physiology. The study monitors muscle disease over a one-week period using these measurements. The process is safe, with no radiation exposure, and does not involve treatment but focuses on observation. Participation involves a series of painless measurements and may include family members with muscle or bone disorders. The total study duration and follow-up depend on individual circumstances.
