Stretch reflex tests are used to determine the integrity of the spinal cord and peripheral nervous system, and they can be used to determine the presence of a neuromuscular disease. [4] The term "deep tendon reflex", if it refers to the muscle stretch reflex, is a misnomer. "Tendons have little to do with the response, other than being ...
The Achilles reflex checks if the S 1 and S 2 [3] nerve roots are intact and could be indicative of sciatic nerve pathology. It is classically delayed in hypothyroidism. This reflex is usually absent in disk herniations at the L 5 —S 1 level. A reduction in the ankle jerk reflex may also be indicative of peripheral neuropathy.
Deep tendon reflexes: Reflexes: masseter, biceps and triceps tendon, knee tendon, ankle jerk and plantar (i.e., Babinski sign). Globally, brisk reflexes suggest an abnormality of the UMN or pyramidal tract, while decreased reflexes suggest abnormality in the anterior horn, LMN, nerve or motor end plate. A reflex hammer is used for this testing.
The myotatic or muscle stretch reflexes (sometimes known as deep tendon reflexes) ... another way of grading is from –4 (absent) to +4 (clonus), where 0 is "normal".
The stretch reflex (myotatic reflex), or more accurately "muscle stretch reflex", is a muscle contraction in response to stretching a muscle. The function of the reflex is generally thought to be maintaining the muscle at a constant length but the response is often coordinated across multiple muscles and even joints. [ 1 ]
Knee jerk or patellar reflex — a kick caused by striking the patellar tendon with a tendon hammer just below the patella, stimulating the L4 and L3 reflex arcs. Moro reflex , a primitive reflex — only in all infants up to 4 or 5 months of age: a sudden symmetric spreading of the arms, then unspreading and crying, caused by an unexpected ...
The triceps reflex, a deep tendon reflex, is a reflex that elicits involuntary contraction of the triceps brachii muscle. It is sensed and transmitted by the radial nerve. [1] The reflex is tested as part of the neurological examination to assess the sensory and motor pathways within the C7 and C8 spinal nerves. [2]
Biceps reflex is a deep tendon reflex (DTR) test (also known as a muscle-stretch reflex test) [1] that examines the function of the C5 reflex arc and the C6 reflex arc. [2] The test is performed by using a tendon hammer to quickly depress the biceps brachii tendon [3] as it passes through the cubital fossa.
