Range of motion in extension of rat knees*

Group	Number of joints	Mean lack of knee extension ± SEM (°)
		Torque 1		Torque 2
		Muscle on	Muscle off†	Muscle on	Muscle off
Experimental
Immobilized	11	51.9 ± 2.8	45.6 ± 2.7	41.9 ± 3.0	34.7 ± 2.9
Contralateral	11	21.1 ± 2.9‡	15.2 ± 2.5‡	10.3 ± 2.3‡	6.5 ± 2.3‡
Control
Sham-operated	8	18.9 ± 2.1‡	15.4 ± 1.4‡	9.8 ± 2.4‡	6.3 ± 2.0‡
Contralateral	8	17.6 ± 2.7‡	11.5 ± 2.4‡	6.9 ± 2.0‡	2.8 ± 2.5‡

* Range of motion measurements correspond to the angular displacement missing to reach complete extension (0°) at the knee; Torque 1 = 667 g/cm; Torque 2 = 1060 g/cm; ^†the muscle off procedure isolated the posterior joint capsule as the tissue limiting knee ROM; ^‡p < 0.05; SEM = standard error of the mean.
