Muscle/movement Impairment Terminology

Question 1

Akinesia

Answer 1

Inability to initiate movement ie

Commonly seen in PD

Question 2

Asthenia

Answer 2

Generalized weakness

Secondary to cerebellar patho

Question 3

Ataxia

Answer 3

Inability to perform coordinated movements

Question 4

Athetosis

Answer 4

Involuntary movements with unstable posture

Peripheral movements without central stabilization

Question 5

Bradykinesia

Answer 5

Slow movement

Question 6

Chorea

Answer 6

Sudden random involuntary movements

Question 7

Clasp-knife response

Answer 7

Resistance seen during range of motion of hypertonic joint where the greatest resistance occurs at the beginning that lessens further through the ROM

Question 8

Clonus

Answer 8

Characteristic of UMN lesion

Involuntary alternating spasmodic contraction of a muscle due to a quick stretch reflex

Question 9

Cogwheel rigidity

Answer 9

Resistance to movement that has a physic quality

Often seen in PD

Question 10

Dysdiadochokinesia

Answer 10

Inability to perform rapidly alternating movements

Question 11

Dysmetria

Answer 11

Inability to control range of movement and force of muscular activity

Question 12

Dystonia

Answer 12

Related to athetosis

Larger axial muscle involvement

Question 13

Fasciculations

Answer 13

Muscle twitch cause by random discharge or LMN and muscle fibers

Question 14

Hemiballism

Answer 14

Involuntary violet movement of large body part

Question 15

Kinesthesia

Answer 15

Inability to perceive direction and extent of movement of body part

Question 16

Lead pipe rigidity

Answer 16

Uniform and constant resistance to ROM

Asssociated with basal ganglia lesions

Question 17

Rigidity

Answer 17

State of severe hypertonicity with sustained muscle contraction

Question 18

Tremor

Answer 18

Involuntary rhythmic oscillatory movements secondary to basal ganglion lesion
