WK10-Spinal Traction Flashcards
What is spinal traction ?
A force that attempts to provide a distractive force to the joints of the spine and widen the IVFs
What is the theory behind traction ?
by increasing the dimensions of the IVF containing the spinal nerve root you may normalize the spinal disc’s position and morphology leading to painful symptoms
What are the three types of traction?
- Mechanical Traction
- Manual Traction
- Positional Traction
Define mechanical traction
application of static or intermittent force by an electrical motor in a distracting position
Define manual traction.
application of force by the therapist in the direction of distracting the joints
Define Positional traction.
prolonged specific positioning to place tension or open the IVF on one side of the spine.
According to the research what are some effects of cervical traction ?
- increased blood flow, fluid exchange, and nutrient transport within the disc
- Increased IVF space: may relieve compression on spinal nerve roots
- Disc herniations may be reduced
- Decrease in pain with some conditions
According to the research what are some effects of lumbar traction ?
- enhanced fluid exchange and nutrient transport within the disc
- Passive traction may lead to reduced intradiscal pressure
- Decrease nerve root compression in some radicular disorders
- expanse of disc material is suggested to reduce disc herniation in some subjects
What are the general indications for traction ?
despite lack of agreement on indications, may be indicated for those with cervical or lumbar spine pain w/ radic.
What are the contraindications to traction?
- Acute spine trauma/ injuries
- Connective tissue disorders like RA, or ankylosing spondylitis
- Osteoporosis and Osteopenia
- History of steroid use or demineralized bone
- spine implants, surgical stabilization
- Pregnancy
- Peripheralization of symptoms
- Non-mechanical pain
What are some precautions to traction ?
COPD, Claustrophobia
When deciding to use mechanical traction what seems to be the consensus for its use ?
If the patient benefits from manual traction then they may be a good candidate for mechanical
How would you adjust the cervical traction machine for a person with lower cervical issues ?
increase the angle of flexion
Explain the proper dosage for Cervical mechanical traction.
total duration: 10-20 minutes
static or intermittent: 30s on : 10 off, 60s on: 20 off
Force: 10-25lbs, 30 max
Explain the proper dosage for Lumbar mechanical traction.
total duration: 10-20 minutes
cycle time:
static or intermittent: 30s on : 10 off, 60s on: 20 off
Force: up to 50% of patients body weight, max. for minimum, 1/4th of patient’s body weight
