30
Q

Acute Back pain

A

may be a result of involvement by muscles and or intervertebral discs

31
Q

Acute back pain Defining characteristics

A
  • Acute: Lasting < 3 months
  • focused history and physical examination
  • Sciatic pain or radiculopathy
  • Affected
  • Gait
  • Reflexes
  • Leg length
  • Leg motor strength
  • Sensory perception

• Paravertebral muscle spasm

32
Q

Back pain Dx

A

• X-ray of the spine: May demonstrate a fracture, dislocation, infection,
osteoarthritis, or scoliosis
• Bone scan and blood studies: May disclose infections, tumors, and
bone marrow abnormalities
• Computed tomography (CT): Useful in identifying underlying
problems, such as obscure soft tissue lesions adjacent to the
vertebral column and problems of vertebral disks
• Magnetic resonance imaging (MRI): Permits visualization of the
nature and location of spinal pathology
• Electromyogram (EMG) and nerve conduction studies: Used to
evaluate spinal nerve root disorders (radiculopathies)

33
Q

Acute back pain Interventions

A

Goal of treatment: Pain relief, return of mobility
• Rest, relaxation & stress reduction
• Pain management
• Patient teaching: sitting, standing, lifting, lying and exercising
• Heat or ice therapy
• Massage therapy
• Physical therapy
• TENS (transcutaneous electrical stimulation)
• Resumption of activity with improvement

34
Q

Back pain pt teaching

A

Standing
Advise the patient to adhere to the following guidelines:
Avoid prolonged standing and walking.
When standing for any length of time, rest one foot on a small stool or box to relieve lumbar lordosis.
Avoid forward flexion work positions.
Avoid high heels.

Sitting
Discuss the following strategies with the patient:
Avoid sitting for prolonged periods.
Sit in a straight-back chair with back well supported and arm rests to support some of the body weight; use a footstool to position knees higher than hips if necessary.
Eradicate the hollow of the back by sitting with the buttocks “tucked under.”
Maintain back support; use a soft support at the small of the back.
Avoid knee and hip extension. When driving a car, have the seat pushed forward as far as possible for comfort.
Guard against extension strains—reaching, pushing, sitting with legs straight out.
Alternate periods of sitting with walking.

Lying
Encourage the patient to do the following:
Rest at intervals; fatigue contributes to spasm of the back muscles.
Place a firm bed board under the mattress.
Avoid sleeping in a prone position.
When lying on the side, place a pillow under the head and one between the legs, with the legs flexed at the hips and knees.
When supine, use a pillow under the knees to decrease lordosis.

Lifting
Emphasize the importance of the following strategies:
When lifting, keep the back straight and hold the load as close to the body as possible.
Lift with the large leg muscles, not the back muscles.
Use trunk muscles to stabilize the spine.
Squat while keeping the back straight when it is necessary to pick something off the floor.
Avoid twisting the trunk of the body, lifting above waist level, and reaching up for any length of time.

Exercising
Daily exercise is important in the prevention of back problems.
Walk daily, and gradually increase the distance and pace of walking.
Perform prescribed back exercises twice daily, increasing exercise gradually.
Avoid jumping and jarring activities.
