Traction Process of drawing, or pulling apart, of a body segment

Mechanical Traction using a traction machine or ropes/ pulleys to apply a traction force

Manual Traction Clinician positions patient and applies traction force to joints of the spine or extremities

Effects of Traction: Spine Encourages movement between each individual spinal segment Amount of movement varies according to… Position of spine, Amount of force, and Length of time the force is applied

Effects of Traction: Spine  pain, paresthesia, or tingling Due to physical separation of vertebral segments thus decreasing pressure on sensitive structures

Effects of Traction: Spine As long as positive physiological effects occur, traction should be continued

Effects of Traction: Bone No immediate effects due to traction May result in increased spinal movement that reverses bone weakness associated with immobilization May assist with increasing or maintaining bone density

Effects of Traction: Discs Normal disc in non-compressed position Internal pressure (indicated by arrows) is exerted equally in all directions Internal annular fibers contain nuclear materials

Effects of Traction: Discs In an injured disc, sitting or standing compresses the disc causing the nucleus to become flatter Pressure in this instance still remains relatively equal in all directions

Effects of Traction: Discs In an injured disk, movement in weight-bearing causes a horizontal shift in nuclear material

Effects of Traction: Discs Herniation of the nuclear material occurs if the annular wall becomes weak Herniation may possibly put pressure on sensitive structures in the area

Effects of Traction: Discs When placed under traction, intervertebral space expands thereby decreasing pressure on the disk Taut annular fibers create a centripetally directed force Decreases herniation and pressure on sensitive structures in the area

Effects of Traction: Articular Facet Joints Facet joints are separated releasing impinged structures Dramatic reduction in symptoms Joint separation decompresses articular cartilage allowing synovial fluid exchange to nourish cartilage Decreases rate of degenerative changes

Effects of Traction: Articular Facet Joints Increased proprioception from facet joint structures provide sensation of pain relief

Effects of Traction: Muscles Vertebral muscles can be stretched Initial stretch should come from body positioning Stretch lengthens tight muscle Allows for better muscular blood flow

Effects of Traction: Muscles Activates muscle proprioceptors providing sensation of pain relief Gate Control Theory

Effects of Traction: Nerves Focus of most traction treatments Pressure on nerves or nerve roots often associated with spinal pain

Effects of Traction: Nerves Unrelieved pressure on a nerve will cause Slowing, eventual loss of impulse conduction Motor weakness, numbness, and loss of reflex Pain, tenderness, and muscular spasm

Traction Treatment Techniques Lumbar Positional Traction Inversion traction Manual Lumbar Traction Level-specific Unilateral leg pull

Traction Treatment Techniques Mechanical Lumbar Traction Manual Cervical Traction Mechanical Cervical Traction

Side-lying Position: Unilateral Foramen Opening Lateral Herniation Patient leaning away from painful side Lie painful side up Lie on right side over blanket roll

Side-lying Position: Unilateral Foramen Opening Lateral Herniation Patient leaning away from painful side Lie painful side up Lie on over blanket roll Medial Herniation Patient leaning toward painful side Lie painful side down Lie over blanket roll

Side-lying Position: Unilateral Foramen Opening Side-lying with a blanket roll between iliac crest and rib cage Increases intervertebral foramen size

Side-lying Position: Unilateral Foramen Opening Maximum opening of intervertebral foramen Achieved by flexing upper hip and knee and rotating shoulders in opposite directions Maximum opening of left side

Supine Position: Bilateral Foramen Opening Knees to chest position increases size of lumbar intervertebral foramen bilaterally Separation of spinous processes

Inversion Traction Hang upside down Lengthens spinal column due to stretch provided by weight of trunk Repeat inversion 2-3 times Observe for signs of vertigo, dizziness, or nausea

Manual Lumbar Traction Used prior to mechanical traction Helps determine degree of lumbar flexion, extension, or side-bending that is most comfortable Most comfortable position is usually best therapeutic position

Level-Specific Manual Traction Position patient for maximum effect at a specific spinal level Lumbar spine flexed using upper leg as lever Palpate interspinous space

Level-Specific Manual Traction Place chest against ASIS and upper hip Lean toward patient’s feet Use enough force to cause a palpable separation of the spinous processes at desired level

Unilateral Leg Pull Manual Traction Sacroiliac problems strap is placed through groin and secured to table Hold ankle and move hip into 30o flexion and 15o abduction Apply steady traction force

Mechanical Lumbar Traction: Equipment Use split table to eliminate friction between body segments Non-slip traction harness stabilizes trunk

Mechanical Lumbar Traction: Setup Pelvic harness Applied while standing Contact pads and upper belt placed at, or just above, iliac crest Rib pads Positioned over lower rib cage

Mechanical Lumbar Traction: Body Positioning Neutral spinal position Allows for largest intervertebral foramen opening before traction is applied Usually position of choice whether prone or supine

Mechanical Lumbar Traction: Body Positioning Flexion Increases posterior opening Puts pressure on disk nucleus to move posterior Other soft tissue may also close foramen opening

Mechanical Lumbar Traction: Body Positioning Extension Closes foramen because bony arches come closer together

Mechanical Lumbar Traction: Body Positioning Prone position Used with normal to slightly flattened lumbar lordosis Best for disk protrusions Place pillows under abdomen

Mechanical Lumbar Traction: Body Positioning Supine position Produces posterior intervertebral separation Optimal at 90o hip flexion Scoliosis, Unilateral joint dysfunction, or Unilateral lumbar muscle spasm

Traction Force No lumbar vertebral separation will occur with traction forces less than 1/4 of body weight Effective traction force ranges between 65 and 200 pounds Traction force recommended = 1/2 body weight

Intermittent vs. Sustained Traction Intermittent Traction Effective for posterior intervertebral separation Sustained Traction Recommended for disk protrusion and rupture

Progressive and Regressive Steps Progressive mode Increases traction force in a pre-selected number of steps Allows slow accommodation to traction Regressive mode Decreases traction force in a pre-selected number of steps Patient comfort is primary consideration!

Manual Cervical Traction Stretches muscles and joint structures Enlarges intervertebral spaces and foramen Creates centripetally directed forces on disk and surrounding soft tissue

Manual Cervical Traction Mobilizes vertebral joints Increases joint proprioception Relieves compressive effects of normal posture Improves arterial, venous, and lymphatic flow

Manual Cervical Traction Variety of head and neck positions Hand should cradle neck contacting one mastoid process Other hand on chin Gentle pull, < 20 pounds Intermittent pull, 3 - 10 sec Treatment time, 3 - 10 min

Mechanical Cervical Traction Supine Neck flexed 20 - 30o Traction harness pulls on occiput Intermittent pull > 20 pounds Minimum of 7 seconds Adequate rest time for recovery Treatment time, 20 - 25 min .

Mechanical Cervical Traction Wall-mounted device Inexpensive Static traction most easily employed Use weight plates, sand bags, or water bags Sitting or prone Gentle pull, 10 - 20 pounds Treatment time, 20 - 25 min

Indications for Spinal Traction Nerve root impingement Disk herniation Spondylolisthesis Narrowing within intervertebral foramen Degenerative joint diseases Subacute pain Joint hypomobility Discogenic pain Muscle spasm or guarding Muscle strain Spinal ligament or capsular contractures Improvement in arterial, venous, and lymphatic flow

Contraindications for Spinal Traction 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
