The muscular strength of the knee was evaluated by measuring the torques exerted on a Biodex knee isokinetic dynamometer at four angular velocities: 0 degrees x s(-1) (T0), 90 degrees x s(-1) (T90), 180 degrees x s(-1) (T180) and 240 degrees x s(-1) (T240). The results of...
It is suggested that testing thigh muscles in the middle sector of knee motion (SR2) yields strength and EMG data that are close and well correlated with those derived from testing the knee along the commonly used (0-90 degrees ) RoM. 展开 ...
the goal is to eventually get symmetrical hyperextension in both of their knees, but not immediately. So if they have 10 degrees of hyperextension on their nonsurgical knee and that’s their normal, I’d probably
The addition of thirty-one newtons (seven pounds) at the foot approximately doubled the quadriceps force that was required to extend the knee. The effective moment arm of the extensor mechanism increased with knee extension, peaked at approximately 20 degrees, and rapidly decreased with further ...
Nine male and nine female subjects performed three maximal concentric reciprocal knee extension and flexion repetitions at 60, 120, 180, 240, 360, and 450 degrees/sec. Extension and flexion results revealed a significant (p < 0.05) increase in acceleration and deceleration range of motion while ...
it is not always necessary for a sensory impulse to reach the brain in order to trigger motor response. A sensory neuron may link directly to a motor neuron at a synapse in the spinal cord, forming a reflex arc that performs automatically. Thus, tapping the tendon below the kneecap causes...
Fifty boy students aging 12-14 years were randomly assigned to 1 of 5 groups: ultrasound therapy (1), ultrasound therapy and 15 sec stretch (2), ultrasound therapy and 30 sec stretch (3), 15 sec stretch (4) and 30 sec stretch (5). The passive knee extension (degrees) was measured ...
In this note, we point out an error to the proof of Theorem 3.4 in Zhang and Xu (Int J Intell Syst 2014;29(12):1061-1078) by a counterexample. We find that the inequality (i.e., |(1)2-(2)2||(1)2-(3)2|) with respect to the degrees of inde... Y Yang,H Ding,ZS Che...
Lies supine the start by the straight body, lifts the both legs upwardly, causes it to have 90 degrees right angles with the upper body, the curving both legs knee, then first is slightly the left leg presses the right leg, then is the right leg presses the left leg, so does ...
