DXA - Future Usage Needs

 The future use of DXA in preventing both muscle and bone loss in the aging population is a challenge that our Institute is very interested in. DXA scans for bone density are well known and are being addressed by the medical profession to prevent osteoporosis. However, the prevention of sarcopenia, which involves decreases in muscle strength, muscle mass, and function, is often overlooked. This is because the assessment of body composition by DXA (or any other method) is largely not carried out by physicians. So, in addition to bone density, DXA offers an assessment of muscle mass in relation to height, and includes various indices that are available to identify those carrying less muscle for their size.

 Our Institute is recommending that physicians assess both muscle mass and bone density status at the same time so that individual loss in muscle can also be identified. There are also simple measures of function that can be performed during a physician’s visit. If sarcopenia is detected, patients can be encouraged to add strength training exercises to their workouts. We have data from an extensive study that indicates women who increase their muscle mass from strength training, increase bone density as well.

 Recent developments in DXA body composition are now emphasizing both bone and muscle mass assessments. In addition, companies such as FitTrace have further developed software, and a handy App, to assess and interpret muscle and lean soft tissue status.

 The Institute is in the planning phase for a future online course that will provide training in these areas of both osteoporosis and sarcopenia. Increasing muscle strength, mass and function in the aging population will help prevent falls, bone fractures and muscle injuries.
