Terminology Flashcards
Sensitivity to loud sounds.
Hyperacusis
Slowed mental state
Abulia
Tonic spasm of the masticatory muscle.
Trismus
It is a reduction in the power that can be exerted by one or more muscles
Weakness
It is the inability to sustain the performance of an activity that should be normal for a person of the same age, sex, and size
Increased fatigabilty
Increased time is required sometimes for full power to be exerted.
Bradykinesia
a disorder of planning and initiating a skilled or learned movement unrelated to a significant motor or sensory deficit
Apraxia
the resistance of a muscle to passive stretch
Tone
Is an increase in tone associated with disease of upper motor neurons.
It is velocity-dependent.
It has a sudden release after reaching a maximum (the “clasp-knife” phenomenon), and predominantly affects the antigravity muscles (i.e., upper-limb flexors and lower-limb extensors)
Spasticity
An increased tone that is present throughout the range of motion (a “lead pipe” or “plastic” stiffness).
It affects flexors and extensors equally.
it sometimes has a cogwheel quality that is enhanced by voluntary movement of the contralateral limb (reinforcement)
Rigidity
It is increased tone that varies irregularly in a manner that may seem related to the degree of relaxation.
It is present throughout the range of motion
It affects flexors and extensors equally.
it usually results from disease of the frontal lobes.
Paratonia (or gegenhalten)
They are visible or palpable twitch within a muscle due to the spontaneous discharge of a motor unit
Fasciculations
