Mechanical Traction

Question 1

Definitions

Answer 1

• Application of mechanical force to the body to separate joint surfaces and elongate surrounding soft tissue
• Applying tension to a body segment

Question 2

Spinal traction

Answer 2

• Lumbar
• Cervical

Question 3

Types of traction units

Answer 3

• Electrical mechanical traction units
• Weighted mechanical traction devices
• Pneumatic mechanical traction devices

Question 4

Proposed Effects of Spinal Traction

Answer 4

• Separation of vertebral bodies
• Widening of intervertebral foramen
• Soft Tissue stretching
• Reduction of Disc Protrusion
• Muscle Relaxation
• Joint Mobilization

Question 5

Indications

Answer 5

• Nerve root impingement
• Disc herniation
• Joint hypomobility
• Paraspinal muscle spasm
• Subacute joint inflammation

*Specific
- Radiculopathy
- DJD of spine

Question 6

Optimal force depends on

Answer 6

• clinical presentation
• treatment goals
• patient positioning
• use lower force initially
• decrease risk of reactive muscle guarding

Question 7

Static traction

Answer 7

• indicated for disc protrusion / herniation
• if symptoms easily aggravated by motion
• use for subacute inflammation
• may prevent stretch reflex of muscles

Question 8

Intermittent traction

Answer 8

• Higher forces can be tolerated
• Can be used for most indications
• Patient comfort often deciding factor
• Recommended for joint dysfunction
