movement

Question 1

Praxis

Answer 1

▪ Understanding the demands of a task and having the ability to cognitively and physically
initiate and implement the necessary movements.

Question 2

▪ Athetosis
▪ Chorea
▪ Dyskinesia
▪ Dystonia
▪ Hemiballismus
▪ Resting tremor
▪ Tics
▪ Tremor

Answer 2

▪ Slow, flailing movements of upper extremities
(UE) and lower extremities (LE)
▪ Sudden, jerky, involuntary movement
▪ Rhythmic, repetitive movements
▪ Sustained muscle contraction
▪ Unilateral violent, thrashing movements
▪ Involuntary oscillating movements seen at rest
▪ Brief, repetitive, nonpurposeful movements
▪ Involuntary oscillating movements caused by
alternating contractions of opposing muscle
groups

Question 3

▪ Asthenia
▪ Ataxia
▪ Dysdiadochokinesia
▪ Dysmetria
▪ Dyssynergia
▪ Intention tremor
▪ Motor impersistence
▪ Rebound
phenomenon

Answer 3

▪ Muscle weakness
▪ Uncoordinated movement patterns
▪ Impaired rapidly alternating
movements
▪ Errors in distance movements
▪ Movement decomposition
▪ Involuntary oscillating movements
during/at end of purposeful
movement
▪ Inability to maintain position
▪ Dysregulation of opposing muscles

Question 4

Sensation and Sensory Testing

Answer 4

Sensations that people receive can be tactile,
auditory, visual, olfactory (smell), gustatory (taste),
or vestibular (balance)
▪ Needed for safe interaction with environment

Question 5

Lead Pipe Rigidity

Answer 5

During PROM, constant resistance is felt throughout (can be seen in Parkinson’s disease).

Question 6

Cogwheel Rigidity

Answer 6

During PROM, resistance is felt at various points throughout the range followed by points of release/easy movement (can be
seen in Parkinson’s disease).

Question 7

Decerebrate Rigidity

Answer 7

Upper and lower extremities are in extension (can occur in clients with lesions in the bilateral hemispheres of the diencephalon
and midbrain)

Question 8

Decorticate Rigidity

Answer 8

Upper extremities are flexed, lower extremities are extended (can occur in clients with bilateral cortical lesions)

Question 9

Clasp Knife Syndrome

Answer 9

After the spastic extremity is given a quick stretch, the OT practitioner will feel
resistance and then the resistance will release.
▪ It is velocity dependent.

Question 10

Clonus

Answer 10

Repetitive, oscillating contractions after a quick stretch is applied to a spastic group of muscles; the number of oscillations that occur is counted and recorded

Question 11

Role of OT in Wound Care

Answer 11

▪ Prevention of pressure injuries
▪ Modification of healing factors
▪ Education of client and family
▪ Seating and positioning
▪ Recommendations regarding adaptive equipment
▪ Modification of ADLs
