In biology, a reflex, or reflex action, is an involuntary, ... another way of grading is from –4 (absent) to +4 (clonus), where 0 is "normal". Reflex modulation
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [1] but not deeper investigation such as neuroimaging.
A list of reflexes in humans. Abdominal reflex; Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. Acoustic reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities.
There are 3 reflexes in the upper arm that are tested. [1] [2] These are the biceps, triceps and supinator reflex. The reflexes may be abnormally brisk or absent. In the latter, the reflex could be elicited through reinforcement by asking the patient to clench their jaw. [2]
Balance is a partly involuntary and unconscious business, dependent on "spinal reflexes." When provided with appropriate context, these reflexes go into oscillation that is called "clonus," a phenomenon that is familiar to everybody and which is easily produced. (While sitting, place the leg with thigh horizontal and foot supported on the floor.
The FOUR Score assesses four domains of neurological function: eye responses, motor responses, brainstem reflexes, and breathing pattern. The rationale for the development of the FOUR Score constituted creation of a clinical grading scale for the assessment of patients with impaired level of consciousness that can be used in patients with or ...
Tendon reflex (or T-reflex) may refer to: The stretch reflex or muscle stretch reflex (MSR), when the stretch is created by a blow upon a muscle tendon. This is the commonly used definition of the term. [1] [2] Albeit a misnomer, in this sense a common example is the standard patellar reflex or knee-jerk response. [3]
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.
