Test review Flashcards
A slowness or lack of spontaneous and automatic movements
Bradykinesia
A movement cannot be followed quickly by its opposite and movements are slow; sign of cerebellar disease
Dysdiadochokinesis
Band of skin innervated by the sensory root of a single spinal nerve
Dermatome
Difficult, poorly articulated speech, resulting from interference in the control over the muscles of speech, usually because of damage to a central or peripheral motor nerve
Dysarthria
Difficulty with gait or balance; inability to coordinate muscle activity during voluntary movement, most often due to disorders of the cerebellum or the posterior columns of the spinal cord.
Ataxia
An abnormal sensation, such as burning, prickling, tickling, or tingling
Paresthesias
Distorted sensations in response to a stimulus and may last longer than the stimulus itself
Dysesthesias
Sudden but temporary loss of consciousness that occurs with decreased blood flow to the brain; fainting
Syncope
A localized, uncoordinated, uncontrollable twitching of a single muscle group innervated by a single motor nerve fiber or filament that may be palpated and seen under the skin. If associated with muscle atrophy, suggest lower motor neuron disease as a cause of the atrophy
Fasciculations
Disorder of peripheral nerves such as inflammation or degeneration. Symmetric weakness of distal muscles suggests this
Polyneuropathy
Dorsiflexion of the big toe often accompanied by fanning of the other toes; may indicate a CNS lesion in the corticospinal tract; may also be seen in drug or alcohol intoxication or in postictal period following seizure
Babinski response
Ankle plantar flexes and dorsiflexes repetitively and rhythmically; sustained clonus indicates CNS disease
Ankle clonus
With arms extended and hands and fingers extended, a sudden, brief, nonrhythmic flexion of the hands and fingers indicates this, suggesting a metabolic encephalopathy
Asterixis
With the patient supine, flex neck forward onto the chest; flexion of hips and knees is a positive sign and suggests meningeal inflammation.
Brudzinski’s sign
With patient supine, flex the patient’s leg at both the hip and knee and then straighten the knee; pain and increased resistance to extending the knee is a positive sign; when bilateral, it suggests meningeal irritation.
Kernig’s sign
Used to assess brainstem function in a comatose patient; holding open the upper eyelids, turn the head quickly to one side and then the other; as the head is turned the eyes move toward the opposite side; if reflex absent, it suggests a lesion of the midbrain or pons
Oculocephalic reflex (doll’s eye movements)
Increased resistance that varies, commonly worse at the extremes of the range of motion; lesion located at UMN of the corticospinal tract at any point from the cortex to the spinal cord; common cause of stroke
Spasticity
Resistance that persists throughout the range and in both directions; common cause is Parkinsonism
Lead-Pipe rigidity
Weakness
Paresis
Absence of strength
Plegia
