5 cze 2023 · Since then, the Achilles reflex test, also called the ankle jerk test, has remained an essential component of the lower extremity neurologic exam. It is a myotatic (deep tendon) reflex that can be elicited easily with a reflex hammer to assess the S1 nerve root of the lumbosacral plexus.
The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed. It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it.
If the reflex being tested is the knee jerk or ankle jerk, have the patient perform the "Jendrassik maneuver," a reinforcement of the reflex (see Gassel, 1964). The patient's fingers of each hand are hooked together so each arm can forcefully pull against the other.
24 lip 2023 · This article will focus on the “deep tendon reflexes” which are more appropriately named — and will be referred to herein — as muscle stretch reflexes (MSR). MSR grading is based on a clinician’s subjective evaluation of amplitude, with a wide range of what can be normal.
Reflex Exam (Deep Tendon Reflexes) The reflex exam is fundamental to the neurological exam and important to locating upper versus lower motor neuron lesions. There are five deep tendon reflexes and a number of superficial and visceral reflexes covered here.
2 dni temu · The ankle jerk is by far the most difficult reflex to master. There are two critical variables: proper stretch and efficient striking. Of the two, proper stretch is the more difficult to learn. If the reflex is difficult to obtain, the patient may be asked to press her foot lightly against the examiner’s hand in order to tense the
Ankle jerks (S1/S2 myotome)—The ankle jerk is the most difficult reflex to elicit, and palpation of the Achilles tendon before striking to ensure the hammer is striking the correct
