Outcome Measures
Primary Outcomes (1)
Echogenicity
Echogenicity values (i.e., image brightness) obtained from the ultrasound scans (units: grayscale levels, 0-255)
1 day
Secondary Outcomes (1)
Muscle thickness
1 day
Interventions
Imaging of the rectus femoris, lower-trapezius, brachioradialis, tibialis anterior, middle deltoid, and pectoralis major will be conducted in Veteran participants during a single visit to the Washington D.C. Veterans Affairs Medical Center. Imaging will be conducted by investigators experienced with quantitative ultrasound using diagnostic musculoskeletal B-mode ultrasound with a 10 Mhz linear transducer.
Eligibility Criteria
Thirty adult Veterans (20-85 years) will be recruited for the study from the DC VAMC.
You may qualify if:
- Male or female Veteran who receives medical care at the Washington DC VA Medical Center
- Ages 20-85
You may not qualify if:
- Limb amputation (upper or lower extremity)
- Lower extremity joint replacement
- Severe cognitive impairment
- Edema
- Inability to read, speak, or understand English
