Indications

1. Herniated Disc Pulposa (HNP) - Rupture of the annulus fibrosis causing pulposa to protrude.

2, Degenerative Joint Disease - ex. Spondylosis (osteoarthritis of neural foramen)

3. Joint Dysfunction (Hypomobility)

4. Muscle Spasm

2

CONTRAINDICATIONS

1. Structural fault due to tumor or infection.

2. Of cervical spine in patients with vascular compromise (stretching an artery the diameter decreases in size, limits blood flow).

3. Where movement is contraindicated (Such as a fracture).

4. Of cervical spine in patients with Rheumatoid Arthritis

5. Of cervical spine in patient with a major neck injury until fracture of the odontoid process has been ruled out. (Or transverse/alnar ligament laxity via motor vehicle accident)

3

Precautions

1. Acute Strains (careful if inflammation is present).

2. Pregnancy (even menstrual cycle, hormones can make you more lax).

3. Osteoporosis (a disease in which the bones become very fragile and likely to fracture).

4. Hiatal Hernia using pelvic traction (hiatal hernia is a condition in which part of the stomach stick upward into the chest, through and opening in the diaphragm.

5. Claustrophobic patients or other safety concerns

Traction Controls

1. Treatment Time
2. Force
3. Duty Cycle
4. Direction of Pull

5

Treatment Time

For Disc Problems:
3-5 minutes for first treatment. Then progress to 8-10 minutes.

For all other problems:
Treat for 15-20 minutes

6

Force

For Cervical Spine:
10% to 20% of the patients body weight (to 35 # MAX). you must add the weight of the head if they are in the sitting position.

For Lumbar Spine:
25% to 50% of the patients body weight, additional force may need to be applied to accommodate for the friction if the table doesn't slide.

7

Duty Cycle

For Disc problems 60 seconds ON and 20 seconds OFF

For all other problems, 20-30 seconds ON and 10 seconds OFF

8

Direction of Pull Transverse Axis

Disc Problems - Direction of pull should be as straight as possible.

Muscle and Facet Problems - Pull with 25 to 30 degrees of flexion.

9

Direction of Pull Longitudinal Axis

(The patients head or trunk list to one side)

Disc Problems - Pull of the side needed to MAINTAIN the list.

Muscle and Facet Problems - Pull on the side to CORRECT the list. (Straighten the patient out)

10

Physical and Physiological Effects of Traction

Uses for spinal traction:

1. Distraction of vertebral bodies (Unloading the disc).

2. Tensing of ligaments.

3. Widening of inter-vertebral foramen.

4. Stretching of spinal musculature.

Note: the relative magnitude of the above effects can be altered by changing the amount of spinal flexion and ectension

11

Type of Spinal Traction

1. Continuous
2. Sustained (Static) Traction
3. Intermittent Mechanical Traction (IMT)
4. Manual Traction
5. Positional Traction
6. Auto Traction
7. Gravity Lumbar Traction

12

Protective Scoliosis

When a protruding nucleus pulposa presses against a nerve root, the patient may lean to one side to pull the nerve root away from the bulge. Depending on where the bulge is, the patient may lean toward or away from the side of pain.

If the patient is listing (leaning) away from the side of the pain, you want to give unilateral traction on the side of the pain to reduce the bulge while sparing the nerve pain.

If the patient is listing toward the side of the pain, you want to give unilateral traction on the side opposite the pain to reduce the bulge while sparing the nerve pain.

13

Continuous Traction

Continuous traction is applied for several hours at a time. because the skin can only withstand low amounts of pressure, continuous traction is limited to weights of 20-30#. This is not enough to cause lumbar vertebral distraction. Many people feel that continuous traction is merely a method of enforcing bed rest.

14

Sustained (Static) Traction

Application of a constant amount of traction for several minutes to half an hour. The less the time, the greater the allowable force. Sustained traction is much more effective if done on a split table which allows the entire force of traction to cause distraction. A regular plinth will have a great deal of friction loss of force.

15

Intermittent Mechanical Traction (IMT)

This form of traction uses a mechanical device to apply and release force every few seconds. IMT is the most type of traction used in the U.S.

16

Manual Traction

Traction applied to the patient by the therapist. Manual traction may be applied slowly or as a sudden thrust. many patients have difficulty relaxing with manual traction because they can't anticipate (or don't trust) what the P.T. will do next.

17

Positional Traction

(using things around the house)
The patient is placed in a certain position with the use of pillows, blocks, or sandbags. gravitational forces are used to provide traction.

18

Auto Traction

The patient applies the traction by pulling with their arms. Te patient therefore controls both the magnitude and direction of the pull.

19

Gravity Lumbar Traction

one end of the patient's body is secured and gravitational force provides the traction. This is most safely performed with the head up, but there is much force placed on the rib cage. In the last decade, there were several devices created which allowed people to hang upside down to create traction. unfortunately, there is a risk of stroke from such a maneuver.
