1

What is therapeutic traction?

Applies longitudinal force to the spine

2

What is therapeutic traction intended to do?

- Mobilize spinal articulations (zygoapophyseal joints)
- Lengthen supportive ligaments
- Decrease muscle spasm
- Decompress vertebral discs
- Decompress compromised nerves (intervertebral foramen)

3

What are the types of traction?

- Continuous: sustained traction using small forces
- Intermittent: alternate traction with relaxation

4

Why would you use a continuous traction?

Allows the supporting structures to 'rest'

5

What are the different methods of application?

- Postural
- Manual
- Automated

6

In what positions can the postural method be applied?

- Hook lying position
- Knees to chest stretch
- Side lying

7

What is the function for the postural application method?

- Widens the posterior elements and the intervertebral foramen
- Allows the patient to find a pain free posture

8

How do you determine which side to lye on for side lying postural traction?

- If the patient leans away from the painful side, that side should be up
- If the patient leans towards the painful side, that side should be down

9

What is inverse traction?

- Requires voluntary muscle relaxation
- Traction for about 70 seconds to promote complete relaxation

10

Blood pressure should not increase more then what?

20 mmHg

11

What are some contraindications to not perform traction on an individual?

- Hypertension (140/90)
- Heart disease
- Glaucoma

12

With what conditions should a medical consult be recommended?

- Diabetes
- Thyroid conditions
- Asthma
- Migraine headaches
- Detached retina
- Hiatal hernias

13

What is manual traction?

Therapist applied traction force

14

What position is most effective for lumbar traction?

Spine in neutral

15

What are the parameters for motorized traction?

- Requires 27-90 Kg of traction
- One half the patients weight is a good estimate for the required traction force
- Treatment time is 8-10 minutes

16

What is sustained traction effective in treating?

Lumbar disc problems

17

How long should a hold be held in intermittent traction of articular joints?

10-20 seconds

18

What does a neutral lumbar spine position allow for traction?

The largest intervertebral foramen opening

19

What happens to the intervertebral foramen during flexion?

Puts pressure on the disc nucleus forcing it to move posterior

20

What happens to the intervertebral foramen during extension?

Closes the foramen down as bony arches come closer together

21

What is the best mechanical body position for disc protrusions?

Prone position with normal to slightly flattened lumbar lordosis

22

What is the best mechanical body position for lordosis?

Controlled by using pillows under abdomen

23

What is the best mechanical body position to produce posterior intervertebral space separation?

Supine position with knees and hips at 90 degrees and supported

24

How much traction force is necessary to cause effective vertebral separation?

Range between 65 and 20 pounds

25

What are the treatment parameters for cervical traction?

- Utilize forces of about 20% of body weight
- Intervertebral separation: 20-30 degrees flexion
- Facet joint separation: 15 degrees extension
- Treatment time: 7 second hold X 10-20 minutes

26

Where does the traction harness for the cervical spine pull?

Mainly on the occiput

27

What is sustained traction recommended for?

Disc protrusion and rupture

28

What is intermittent traction recommended for?

Posterior intervertebral separation

29

What is the total treatment time for suspected disc protrusions?

Relatively short, 10 minutes or less.

30

When should a treatment time for a suspected disc protrusions be increased or decreased?

Increased: if first treatment was partially successful or unsuccessful (up to 30 minutes)
Decreased: if first treatment was successful

31

What are some traction indications?

- Nerve root impingement
- Disc herniation
- Spondylolisthesis
- Narrowing within intervertebral foramen
- Osteophyte formation
- Degenerative joint diseases
- Subactue pain
- Joint hypomobility
- Discogenic pain
- Muscle spasm or guarding
- Muscle strain
- Spinal ligament contractures
- Improvement in arterial, venous and lymphatic flow

32

What are some traction contraindications?

- Acute sprains or strains
- Acute inflammation
- Fractures
- Vertebral joint instability
- Any condition in which movement exacerbates existing problem
- bone diseases
- Osteoporosis
- Infections in bones or joints
- Vascular conditions
- Pregnant females
- Cardiac or pulmonary problems
