Kinematic data included knee flexion, pronation, time to maximum knee flexion, and time to maximum pronation.
Postoperative knee flexion and time to climb stairs were similar between the groups.
A fourth knee dislocated in deep flexion three times, 11, 39, and 52 months after surgery, and each time was treated by closed reduction.
Data on six physical performance tests were collected in NHANES III by trained assessors: repeated chair rise test, 8-foot walk, lock and key test, shoulder range of motion, active hip and knee flexion, and timed tandem stand test [ 16, 22- 25].
Swing times (flexion) were increased in all limbs, whereas stance time (extension) was increased in forelimbs (Fig. 2e, f).
Results: The angle of flexion increased over time and was largely explained by bone growth (r =.725, p <.01).
Of those participants that attended >85% of classes, an increase was observed in the average number of push-ups, trunk flexion, and balance time on each foot.
Experiments were conducted using a mechanical hinge analog of the knee to verify that time, flexion angle, and knee extension force measurements recorded when using the simulator were not influenced by its design or operation.
Compressive force is exerted vertically to the spinal column with neck in the neutral position (30-degree flexion) at the time of injury, resulting in pure axial loading injury and compressive failure of the anterior column.
