Question 1

Early stage Parkinson disease is highly correlated with this type of hypertonia.

Accepted Answer

Cogwheel rigidity is a type of hypertonia associated with Parkinson's disease. It is characterized by a ratchety resistance to passive movement as muscles alternately tense and relax.

Question 2

A patient presents with decerebrate rigidity.The lesion most likely responsible for this abnormal posturing is located within the __________.

Accepted Answer

Decerebrate rigidity is characterized by extension of the arms and legs, pronation of the arms, and plantar flexion of the feet. This type of posturing is indicative of damage to the brainstem, specifically within the area where the extrapyramidal tracts are located. These tracts are involved in involuntary movement control, and damage to them can result in this abnormal posture.

Question 3

Which of the following therapeutic inhibition techniques is least effective to reduce hypertonicity of the upper extremity:

Accepted Answer

D

Question 4

Spasticity is defined as which of the following:

Accepted Answer

Spasticity is characterized by an increase in muscle tone that becomes more pronounced with faster movements, making option A correct. This is a hallmark of upper motor neuron syndrome.

Question 5

When applying motor level stimulation to address spasticity of the following settings which is the most important?

Accepted Answer

Appropriate ramp up time is crucial in motor level stimulation to prevent sudden muscle contractions that can exacerbate spasticity.

Question 6

Aquatic therapy has demonstrated effectiveness as a means of therapeutic exercise for individuals with hypertonicity.The main principle that allows for a therapeutic effect is which of the following?

Accepted Answer

The answer of Aquatic therapy has demonstrated effectiveness as a...

Question 7

A patient presents with a slight increase in muscle tone,manifested by a catch,followed by minimal resistance throughout the remainder (less than half) of the range of motion (ROM).The corresponding score on the Modified Ashworth Scale is as follows:

Accepted Answer

The Modified Ashworth Scale score of 1+ indicates a slight increase in muscle tone, manifested by a catch followed by minimal resistance throughout less than half of the ROM.

Question 8

Hypertonicity in the biceps and the flexor digitorum profundus (FDP) may result in which of the following contractures and subsequent functional limitations?

Accepted Answer

Hypertonicity in the biceps and the flexor digitorum profundus (FDP) would lead to a tendency for both elbow flexion and wrist flexion due to the primary actions of these muscles. This could result in contractures that limit the ability to extend the elbow and wrist, thereby affecting the ability to reach and grasp objects effectively, particularly with a lumbrical grip which requires a more extended wrist position for optimal function.

Question 9

Which of the following pharmaceutical interventions may be administered orally or via intrathecal catheter?

Accepted Answer

Baclofen can be administered both orally and via an intrathecal catheter. Oral baclofen is used for treating spasticity, while intrathecal baclofen, delivered directly into the spinal fluid, is used for severe spasticity when oral administration is not effective.
