Hyporeflexia is diagnosed through a neurological examination that evaluates the deep tendon reflexes (DTRs) using a reflex hammer. Some of the common reflexes tested include the biceps, brachioradialis, and triceps reflexes in the arm, as well as the patellar and Achilles reflexes in the leg. Normally, tapping the reflex hammer at specific tendon should elicit an immediate contraction in the ...
Patellar grind test With the patient supine and the knee flexed to 10–20º, grasp the distal thigh and proximal patella, apply anterior to posterior pressure on the patella, and instruct the patient to contract the quadriceps muscle.
The most commonly identified type of stretch reflex is the knee jerk reflex, where tapping the patellar tendon (i.e., the tendon located at the front of the knee) causes the foot to kick forward. This reflex is a type of deep tendon reflex tested during a neurological examination to identify abnormalities within this reflex arc.
Healio: Patellar apprehension could identify patients with patella alta and trochlear dysplasia
Patellar dislocation is a relatively uncommon knee injury. Only accounting for approximately 2–3% of all knee injuries, patellar dislocations most commonly affect young and active individuals, with a higher risk among adolescent females and athletes.
Quadriceps tendonitis, also known as “jumper’s knee,” is a musculoskeletal condition characterized by inflammation of the quadriceps tendon. The quadriceps tendon connects the quadriceps muscles located at the front of the thigh to the patella, or kneecap. The patellar tendon then connects the patella to the tibia, or shinbone. Collectively, the quadriceps tendon and patellar tendon ...
Patellar tendon rupture is a rupture of the tendon that connects the patella to the tibia. The tell-tale sign of a ruptured patella tendon is the movement of the patella further up the quadriceps.
