What is therapeutic traction?

Applies longitudinal force to the spine


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)


What are the types of traction?

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


Why would you use a continuous traction?

Allows the supporting structures to 'rest'


What are the different methods of application?

- Postural
- Manual
- Automated


In what positions can the postural method be applied?

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


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


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


What is inverse traction?

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


Blood pressure should not increase more then what?

20 mmHg


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

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


With what conditions should a medical consult be recommended?

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


What is manual traction?

Therapist applied traction force


What position is most effective for lumbar traction?

Spine in neutral


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


What is sustained traction effective in treating?

Lumbar disc problems


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

10-20 seconds


What does a neutral lumbar spine position allow for traction?

The largest intervertebral foramen opening


What happens to the intervertebral foramen during flexion?

Puts pressure on the disc nucleus forcing it to move posterior


What happens to the intervertebral foramen during extension?

Closes the foramen down as bony arches come closer together


What is the best mechanical body position for disc protrusions?

Prone position with normal to slightly flattened lumbar lordosis


What is the best mechanical body position for lordosis?

Controlled by using pillows under abdomen


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

Supine position with knees and hips at 90 degrees and supported


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

Range between 65 and 20 pounds


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


Where does the traction harness for the cervical spine pull?

Mainly on the occiput


What is sustained traction recommended for?

Disc protrusion and rupture


What is intermittent traction recommended for?

Posterior intervertebral separation


What is the total treatment time for suspected disc protrusions?

Relatively short, 10 minutes or less.


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


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


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
