A 62-year-old male with a spinal cord injury from a fall has preserved motor function in the upper extremities but cannot move his lower extremities against gravity. Sensory testing shows decreased pain and temperature sensation below the injury level, but proprioception and vibration sense are intact. What is the ASIA impairment scale classification and possible SCI syndrome?

A

AIS B: Incomplete. Likely an Anterior Cord Syndrome, characterized by loss of motor function and pain/temperature sensation but preserved proprioception and vibration sense.

7
Q

A

AIS B: Incomplete. Likely Brown-Sequard Syndrome, characterized by ipsilateral loss of motor function and proprioception, and contralateral loss of pain and temperature sensation.

8
Q

A) X-ray
B) CT scan
C) MRI
D) Somatosensory Evoked Potentials (SSEP)

A

D) Somatosensory Evoked Potentials (SSEP)

8
Q

A

Brown-Séquard Syndrome

8
Q

Which SCI syndrome is characterized by more severe involvement of the upper extremities than the lower extremities?

A) Anterior cord syndrome
B) Central cord syndrome
C) Brown-Séquard syndrome
D) Posterior cord syndrome

A

B) Central cord syndrome

9
Q

A 25-year-old female with a history of multiple sclerosis (MS) presents with progressive weakness and sensory loss. Sensory testing reveals loss of pain and temperature sensation in the lower extremities, but proprioception and vibration sense are preserved. What should be considered in the differential diagnosis?

A

Multiple sclerosis (MS). Although MS can present with sensory and motor deficits similar to SCI, it is important to differentiate between MS and SCI as the management and underlying pathology are different.

9
Q

A 45-year-old male was in a motorcycle accident and presents with no sensation or motor function below the level of T6. He has preserved sensation in the sacral segments (S4-S5) but no motor function in the same segments. What is the ASIA impairment scale classification?

A

AIS A: Complete. There is no motor or sensory function preserved below the level of the injury, including the sacral segments S4-S5.

9
Q

A 30-year-old female sustained a spinal cord injury from a fall. She has sensation in all dermatomes below the level of injury but cannot move her legs against gravity. At least half of the key muscles below the level of injury have a muscle grade less than 3. What is the ASIA impairment scale classification?

A

AIS C: Incomplete. Motor function is preserved below the neurological level, but more than half of the key muscles below the level of injury have a muscle grade less than 3.

9
Q

A 70-year-old male with a spinal cord injury from a fall presents with symptoms including pressure ulcers, spasticity, and deep vein thrombosis (DVT). What are some of the common complications associated with SCI?

A

Common complications include pressure ulcers, autonomic dysreflexia, orthostatic hypotension, heterotopic ossification, contractures, pain, spasticity, sexual dysfunction, deep vein thrombosis, and respiratory compromise.

Q

Which SCI syndrome is characterized by ipsilateral paralysis and loss of proprioception, with contralateral loss of pain and temperature sensation?

A

10
Q

What are the indications for surgical stabilization of spinal injuries?

BWSTT leads to greater improvements in hip extension during stance and plantarflexion during preswing compared to conventional training.

10
Q

True or False: The primary goal of physical therapy during the chronic stage of SCI rehabilitation is to focus on maximizing functional independence and addressing long-term needs such as psychological support and assistive device training.

A

True

10
Q

True or False: Anterior Cord Syndrome is characterized by preserved proprioception and vibration sense, with loss of motor function and pain/temperature sensation below the level of the injury.

A

True

Q

True or False: Early mobilization in SCI patients should only begin after the surgeon has cleared the patient for activity.

A

TRUE

11
Q

What should be assessed during the initial physical therapy examination of a spinal cord injury patient?

A

Respiratory function, muscle strength, muscle tone, reflex activity, skin status, cardiac function, and functional mobility skills.

12
Q

What are common complications associated with spinal cord injuries that physical therapy needs to address?

A

Pressure ulcers, autonomic dysreflexia, orthostatic hypotension, heterotopic ossification, contractures, pain, spasticity, sexual dysfunction, deep vein thrombosis, and respiratory compromise.

12
Q

What are common complications associated with spinal cord injuries that physical therapy needs to address?

A

12
Q

Which breathing exercise technique is recommended for patients with high-level tetraplegia?

A

Glossopharyngeal breathing, which involves trapping air in the throat to aid breathing.

13
Q

Fill in the blank: During acute care, patients with spinal cord injuries should be evaluated for their _______ to upright positioning and be monitored for orthostatic hypotension.

A

Tolerance

13
Q

What is the main goal of rehabilitation in the chronic stage for SCI patients?
