To test the reflex, the muscle should be in a neutral position. The muscle being tested needs to be flexed for the clinician to locate the tendon. After the muscle is relaxed, the clinician strikes the tendon. The response should be contraction of the muscle. If this is the knee jerk reflex, the clinician should observe a kick.
Depending on how the defense responds, the driving player can either shoot a lay-up, pass to the post player for a shot, or "kick-out" pass to one of the perimeter players. If the ball is returned to the perimeter, the player that receives the pass either takes a three-point shot, or dribble-drives to the basket, restarting the process.
The patellar reflex, also called the knee reflex or knee-jerk, is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord. Many animals, most significantly humans, have been seen to have the patellar reflex, including dogs, cats, horses, and other mammalian species.
Arizona reliever Kevin Ginkel escaped with only a bruise when hit on the inside of his left knee by a 98.3 mph comebacker off the bat of the New York Mets' Brandon Nimmo in the sixth inning of a ...
The Jendrassik maneuver to reinforce knee-jerk. The Jendrassik maneuver is a medical maneuver wherein the patient clenches the teeth, flexes both sets of fingers into a hook-like form, and interlocks those sets of fingers together. The tendon below the patient's knee is then hit with a reflex hammer to elicit the patellar reflex. The elicited ...
On the contralateral side (the one that bears all the weight), the flexors relax and the extensors contract to stiffen the leg since it must suddenly support the entire weight of the body. At the same time, signals travel up the spinal cord and cause contraction of the contralateral muscles of the hip and abdomen to shift the body’s center of ...
Patellar subluxation syndrome is an injury involving the kneecap.Patellar subluxation is more common than patellar dislocation and is just as disabling. [1]In this condition, the patella repetitively subluxates and places strain on the medial restraints and excessive stress/tension on the patellofemoral joint.
