Course Overview

Dual energy x-ray absorptiometry (DXA) traditionally has been used by physicians for diagnosing osteoporosis, assessing fracture risk, and monitoring changes in bone mineral density. This low-cost, low-radiation, and easily-accessed modality also detects abnormalities in body composition and clinical obesity,[1] determines the effects of diet, exercise, and physical training for patients attempting to lose or control weight; and tracks muscle growth and fat mass to improve or enhance health.[2-5] Coupled with metabolic assessment, DXA analysis of body composition offers the care provider a potent educational tool for educating and guiding patients to improved health that can be measured over time.

This lecture reviews the current parameters used to measure health and fitness, discuss how DXA is different from traditional evaluations in measuring health and fitness, and describe how DXA and metabolic testing work together to improve patient health and well-being.

Joseph B. Norris, MD

Dr. Norris received his medical degree from Southern Illinois University School of Medicine, where he also completed a residency in orthopedic surgery. His surgical residency was followed by a fellowship in sports medicine at Union Memorial Hospital in Baltimore.

Dr. Norris currently is in private practice at McLean County Orthopedics in Bloomington, IL, where he performs complex shoulder, hip, and knee arthroscopy, as well as shoulder arthroplasty. He is also certified for cartilage restoration procedures.

Complementing his surgical practice is involvement in McLean County Orthopedics’ Body Composition Program, which helps patients achieve their health, fitness, and weight loss goals. Metabolic testing and DXA scan results allow the specialized medical team the ability to craft a personalized exercise prescription for educating and guiding each patient on their fitness journey.
