Abnormal Reflex (procedure)
Abnormal reflex: a neurological examination finding and procedure covering increased, decreased, or absent reflexes (hyperreflexia, hyporeflexia), graded on scales such as Mayo and NINDS, indicating upper or lower motor neuron lesions.
Head impulse test
The head impulse test, also called the head thrust test, is a bedside maneuver that assesses the vestibulo-ocular reflex to detect unilateral inner-ear balance dysfunction.
Modified Ashworth scale
The Modified Ashworth scale is a six-grade ordinal scale rating resistance felt during passive limb movement, the most widely used clinical measure of increased muscle tone.
Pronator drift
Pronator drift is a bedside neurological examination maneuver in which pronation and downward drift of one outstretched arm indicate a contralateral upper motor neuron lesion.
Pupillometry
Pupillometry, also called quantitative pupillometry, is a diagnostic method that measures pupil size and light reflex dynamics with handheld infrared devices, used to assess neurological status and intracranial pressure in critically ill patients.
Quantitative sensory testing
Quantitative sensory testing (QST) is a standardized, non-invasive psychophysical method measuring detection and pain thresholds for thermal, mechanical, and vibratory stimuli to assess sensory nerve function.
Somatosensory stimulation
Somatosensory stimulation applies electrical stimuli to the body's sensory pathways to assess nervous system function or treat chronic pain and spasticity, spanning techniques from TENS to spinal cord stimulation.
Video head impulse test
The video head impulse test (vHIT) is a clinical vestibular test in which video goggles record eye movements during rapid head turns to measure the vestibulo-ocular reflex.
