All of the subjects unable to walk 1 0 or 5 0 ft had LEPf, LEPg and LEPb less than 0.38, 0.88 and 1.17 W/kg respectively.
Values of leg extensor Rower (in fractured and uninjured leg), weight, normalized leg extensor power and sway for all subjects (Median and 90% central range, n = 40) Median 90% CR LEPf (W) 18 7-41.7 LEPg (W) 42 25.1-77.8 Weight (kg) 56 42.1-81.3 LEPf (W/kg) 0.35 0.111-0.629 LEPg (W/kg) 0.75 0.436-1.41 LEPb (W/kg) 1.1 0.631-2.02 LEPdiff (W/kg) 0.42 0.174-0.816 Sway (cm/1 min) 24.8 14.01-42.39 For explanation of abbreviations see Methods section of text.
The eight women unable to climb the stairs all had LEPF < 0.38W/kg, LEPg < 0.89W/kg, LEPb 1.1 W/kg and sway > 21.2 cm/ 1 min.
LEPf and sway made significant and independent contributions to 10-ft walking speed, with LEPf accounting for 40.3% of the variance, and postural sway an additional 10% (Equation 1, Table VI).
A second analysis excluding these subjects yielded an equation in which LEPf was the only factor to account for variance in speed; postural sway or fracture pattern did not contribute (Table VI, Equation 2).
Variance in stair-climbing time: LEPf and pain explained 44% of the variance in stair-climbing speed (Equation 4).
Variance in leg extensor power and postural sway: LEPf and LEPg were correlated negatively with pain; only LEPg was correlated to pre-injury mobility.
