Table 3. Pearson correlation for DEXA results compared with functional tests.
| MEASURE | Total body lean mass | Lean mass of the right arm | Right grip | Right pinch | Right jaw chuck |
|---|---|---|---|---|---|
| Total body lean mass | 1.00 | ||||
| Lean mass of the right arm | 1.00 | ||||
| Right grip | 0.84 P<0.001 | 0.91 P<0.0001 | 1.00 | ||
| Right lateral pinch | 0.76 P<0.001 | 0.83 P<0.0001 | 0.94 P<0.0001 | 1.00 | |
| Right jaw chuck | 0.73 P<0.001 | 0.77 P=0.0009 | 0.86 P<0.0001 | 0.78 P<0.0001 | 1.00 |
| MEASURE | Total body lean mass | Lean mass of the right leg | 2MWT | 6MWT | 10m walk |
| Total body lean mass | 1.00 | ||||
| Lean mass of the right leg | 1.00 | ||||
| 2MWT | 0.62 P=0.001 | 0.59 P=0.0047 | 1.00 | ||
| 6MWT | 0.62 P=0.001 | 0.62 P=0.0034 | 0.98 P<0.0001 | 1.00 | |
| 10m walk* | -0.39 P=0.066 | -0.38 P=0.1345 | -0.73 P<0.0001 | -0.76 P<0.0001 | 1.00 |
*
An inverse correlation is found between lean mass of the right leg and 10m walk, as increasing lean mass should result in less time to complete the 10m walk.
