Q

What is Somatosensory Input.

A

It is the proprioceptive input you receive from your joints. muscles, ligaments, and skin regarding length, tension, pressure, pain, and joint position in order to keep you balanced.

Q

What are some examples of Vestibular Tests?

A

-Dix-Hallpike Test: The patient is quickly lowered to supine with their neck extended to approximately 30 degrees, then their eye movements are examined

-Bithermal Caloric Testing: The patients ear canals are irrigated with water at different temperatures, then their eye movements are examined.

-Nystagmus Assessment: Different tests to analyze the type of nystagmus the patient has.

-Head Thrust Sign: The patent’s head is quickly thrusted in multiple directions while they try to maintain their gaze on a fixed object; the patient should be able to maintain a fixed gaze.

Q

What is the Suspensory Strategy?

A

It is used in conjunction with the ankle, hip, and stepping strategies. It is when you lower your center of gravity to maintain balance. This strategy is often used when both mobility and stability are required during a task (such as surfing).

Q

Describe the Functional Reach Test

A

It is just like the reaching portion of the Berg, but it utilizes age related reaching norms (20-40, 41-69, 70-87). If the patient falls below the age appropriate range for functional reach, they are at an increased risk of falling.

Q

Describe the Timed Up and Go Test

A

It test the patients balance by having them quickly stand up from a chair, walk approximately 10 feet, turn around, walk back, and sit back down. A patient who can do it in 10 seconds or less is considered independent, over 20 seconds is considered increased risk for falling, and over 30 seconds is considered high risk for falling.

Q

Describe the Tinetti Performance Oriented Mobility Assessment.

A

It assesses balance through a STS section and a gait section. The first section has a maximum score of 16 and the second section has a maximum score of 12, with a total max score of 28. A total score less than 19 indicates a high risk for falls.

Q

What is Broca’s Aphasia?

A

A lesion to the frontal lobe causes expressive aphasia (the most common type of aphasia), impaired repetition and naming skills, and paraphasias.

26
Q

What is Global Aphasia?

A

A lesion to the frontal, temporal, and parietal lobes which results in receptive and expressive aphasia. The patient may involuntarily verbalize (usually without correct context), and may use nonverbal skills for communication.`

27
Q

What are some tips for treating a patient with Aphasia?

A

-Try to limit verbal cueing; instead, use tactile and visual cues

-Try to limit background noise and multiple voices; this is distracting

-Use concise sentences and yes or no questions

-Allow the patient plenty of time to process and respond

-Account for extra time needed during session for communication needs. Rushing communication will increase frustration.

-Try to limit repetitive feedback

28
Q

What is Apraxia?

A

It is an impairment to motor planning which affects verbalization. (similar to expressive aphasia, but stems from impaired motor planning abilities).

29
Q

What is Dysarthria?

A

It is an impairment to motor function which affects verbalization. (similar to expressive aphasia, but stems from impaired motor control)

30
Q

What are the Cranial Nerves and what do they do?

A

1: Olfactory (sense of smell)

4: Trochlear (motor for vision in downward/medial direction)
5: Trigeminal (senses of the face AND motor for chewing
6: Abducens (motor for vision in the lateral directions)
7: Facial (sense of anterior tongue taste AND motor for facial expressions)
8: Acoustic/Vestibulocochlear (sense of hearing and balance)
9: Glossopharyngeal (sense of taste for posterior tongue and motor for swallowing)
10: Vagus (regulates internal organ function and reflexes such as coughing, sneezing, swallowing, and vomiting)
