Muscle/movement Impairment Terms Flashcards
Akinesia
Inability to initiate movement; commonly seen in patients with Parkinson’s
Asthenia
Generalized weakness, typically secondary to cerebellar pathology
Ataxia
Inability to perform coordinated movements
Athetosis
Condition that presents with involuntary movements combined with instability of posture. Peripheral movements occur without central stability
Bradykinesia
Very slow movement
Chorea
Movements that are sudden, random, and involuntary
Clasp-knife response
Form of resistance seen during range of motion of a hypertonic joint where there is greatest resistance at the initiation of range that lessens with movement through the ROM
Like opening pocket knife
Clonus
Characteristic of upper motor neuron lesion, involuntary alternating spasmodic contraction of a muscle brought on by a quick stretch reflex
Cogwheel rigidity
Rigidity where resistance to movement has phasic quality to it; often seen with Parkinson’s
Dysdiadochokinesia
Inability to perform rapidly alternating movements
Dysmetria
Inability to control the range of movement and the force of muscular activity
Can’t reach and grab pen/tissue—I think
Fasciculation
Muscular twitch that is caused by random discharge of lower motor neuron and its muscle fibers; suggests lower motor neuron disease, however, can be benign
Hemiballism
Involuntary and violent movement of large body part
Kinesthesia
Ability to perceive The direction and extent of movement of a joint or body part
Lead pipe rigidity
Form of rigidity where there is uniform and constant resistance to range of motion; often associated with lesions of basal ganglia
