30
Q

What is Cervical Radiculopathy?
What Causes it?
Goals of treatment?

A
  • Mechanical compression or inflammation of a nerve root that causes neurological symptoms into upper extremities
  • Caused by disc herniation, spondylosis, osteophytes (bone spurs)
  • Relieve symptoms, reduce pain/swelling, control muscle spasms, centralize symptoms
31
Q

How to treat Disc Herniation

A

Gradually strengthen directions that relieve pain and avoid those that make pain worse

32
Q

What is Cervical Spondylosis?
Age group?
Treatment?

A
  • Chronic disc disease from wear and tear that leads to degeneration of bones
  • Mostly in men ages 40-50 in C5-C6 or C6-C7
  • Treatment: Thermal or Electrical modalities
  • Traction
  • Flex exercise (bc usually pain with ext) and axial rotation
  • Functional AROM exercises
  • Cervical isometrics
  • Education on posture exercises, flexibility and stability
33
Q

What needs to be strengthened in patients that suffer from Headaches?

A

Scapula and deep neck flexors

34
Q

What causes Thoracic Outlet Syndrome of the cervical spine?

Treatment?

A

Compression of vascular and or neurological tissues as they exit the superior triangle opening of thorax

  • Causes: cervical rib, shortened anterior scalene, malunion of clavicle and first rib or tight pectoral muscles
  • Treatment: posture education, stretching ant scalene and pecs, strengthening scap retraction, thoracic ext, rowing, educate on protection or possible surgery
35
Q

How do you exercise the Deep Neck Flexors?

A

Chin Tucks = craniocervical flexion

Supine (Easy)
Sitting or Standing
Prone
Add in another movement like walking or squats (Hard)

36
Q

What cues would you give a pt to activate the cervical core muscles?

A

Head flexion and slight flattening of the cervical lordosis

37
Q

Which side of the Scoliosis curve do pt have ligament strains and which side mobility impairments?

A

Ligament strains = ConVEXity

Impairments = ConCAVE

38
Q

What is the treatment for Scoliosis?

A
Strengthening muscles on convex side
Stretch muscles on concave side
Trunk elongation exercises
Bracing
Correct Leg Length Discrepancy
Surgery for curves over 5-60*
39
Q

Which level is the most rare disc injury to occur?

A

Thoracic because of the articulation with the rib cage adds more support

40
Q

What are treatments for Disc Injuries?

A

Analgesics, modalities, epidural injections, surgery if severe, bracing, progress AROM, strengthening, endurance activities, return to function with limitations specific to fusion

41
Q

What are treatments for Thoracic Kyphosis?

A

Posture awareness, strengthen scapular retractors, stretch anterior shoulders, breathing exercises

Define: Protrusion, Extrusion and Sequestration
