Measuring techniques for sarcopenia
| Measuring techniques | Measurements | Comments |
|---|---|---|
| Muscle size | ||
| CT Scan | Muscle cross-sectional area | Radiation exposure, expensive |
| MRI Scan | Muscle cross-sectional area | Expensive, availability of MRI |
| BIA | Tissue conductivity | ? reliability |
| Muscle circumferences | Mid arm and calf circumference | Measurements effected by subcutaneous fat |
| DXA scan | Total skeletal muscle mass | Reliable, low radiation exposure |
| Physical performance | ||
| SPPB | Lower extremity function | Validated tool for older people |
Abbreviations: CT, computed tomography; MRI, magnetic resonance imaging; BIA, bioelectric impedence analysis; DXA, dual energy X-ray absorptiometry; SPPB, Short Physical Performance Battery.
