Traction AndTraction Of Different Body Parts

Spinal Traction

—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

—Traction

—It is a form of decompression therapy that relieves pressure on the spine that can performed manually or mechanically.

—It is used to treat

— herniated discs,

—sciatica,

— degenerative disc disease,

— Traction

pinched nerves,—and many other back conditions

It stretches the spine to take pressure off compressed discs. This straightens the spine and improves the body’s ability to heal itself.

Manual Spinal 

—In This, a physical therapist uses his hands to put a patient in a state of traction. Then he or she uses manual force on the joints and muscles to widen the spaces between vertebrae.

.Traction

Mechanical Spinal 

—In mechanical spinal traction, a patient lies on a table that has special tools to stretch the spine. A physical therapist will attach a series of ropes, slings, and pulleys to the patient to mechanically relieve pressure.

—Spinal traction is a non-surgical way to relieve pain and correct problems in the spine. While it does have some potential side effects, spinal traction offers consistent relief for most patients

—There are no long-term risks of spinal traction. Some side effects may occur during or after treatment. Many patients experience muscle spasms after traction. Some have pain in the treated areas.

—Spinal traction is not for everyone. A physician can determine if the risks are worth the potential rewards.

—Traction

—Effects: Spine

—Encourages movement between each individual spinal segment

—Amount of movement varies according to…

—Position of a spine,

—Amount of force, and

—Length of time force is applied

—Transient effect—

—Effects: Spine

—¯ pain, paresthesia, or tingling

—Due to the physical separation of vertebral segments thus decreasing pressure on sensitive structures

—As long as positive physiologic effects occur, traction should  be continued

—Effects: 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: Ligaments

—Stretching effect

—Structural changes occur slowly due to viscoelastic properties

—Ligaments resist shear forces and return to original form following removal of a deforming load

—Sensitivity to a rate of loading

—Ligament deformation results in a lengthening of a ligament caused by traction loading.

—Effects: 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: Discs

—In an injured disc, sitting or standing compresses the disk causing the nucleus to become flatter

—Pressure in this instance still remains relatively equal in all directions

—Effects: Discs

—In an injured disk, movement in weight-bearing causes a horizontal shift in nuclear material

—If this was forward bending, the bulge would occur in the posterior annular fibers

—Anterior annular fibers would be slackened and narrow

—

—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: 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: Articular Facet Joints

—Facet joints are separated releasing impinged structures

—Dramatic reduction in symptoms

—Joint separation decompresses articular cartilage allowing the synovial fluid exchange to nourish cartilage

—Decreases rate of degenerative changes

—Increased proprioception from facet joint structures provide a sensation of pain relief

—Effects: Muscles

—Vertebral muscles can be stretched

—Initial stretch should come from body positioning

—Stretch lengthens a tight muscle

—Allows for better muscular blood flow

—Activates muscle proprioceptors providing a sensation of pain relief.

—Effects: Nerves

—Focus of most traction treatments

—Pressure on nerves or nerve roots often associated with spinal pain

—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—

—Inversion traction

—Manual Lumbar Traction

—Level-specific

—Unilateral leg pull

—Mechanical Lumbar Traction

—Manual Cervical Traction

—Mechanical Cervical Traction

—Lumbar Positional 

—Patient typically on a restricted activity program

—“Trial and error” process to determine the position that offers maximum comfort

—

—Side-lying Position: Unilateral Foramen Opening

—Lateral Herniation

—Patient leaning away from painful side

—Lie painful side up

—Lie on the 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 the right side over blanket roll

—Medial Herniation

—Patient leaning toward the painful side

—Lie painful side down

—Lie on the right side over blanket roll

—

—Side-lying Position: Unilateral Foramen Opening

—Side-lying with a blanket roll between the iliac crest and rib cage

—Increases intervertebral foramen size of a superior side of the lumbar spine

—Side-lying Position: Unilateral Foramen Opening

—Maximum opening of intervertebral foramen

—Achieved by flexing upper hip and knee and rotating shoulders in opposite directions

—Supine Position: Bilateral Foramen Opening

—Knees to chest position

—increases the size of lumbar intervertebral foramen bilaterally

—Separation of spinous processes

—Inversion Traction

—Hang upside down

—Lengthens spinal column due to stretch provided by the weight of the trunk

—Repeat inversion    2-3 times

—Observe for signs of vertigo, dizziness, or nausea—

—Manual Lumbar Traction

—Used prior to mechanical traction

—Helps determine a 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 a lever

—Palpate interspinous space

—Upper spinous process is where the maximum effect is desired

—

—Level-Specific Manual 

—When a motion of lower spinous process can be palpated, place foot against the opposite leg to prevent further flexion

—Trunk is then rotated toward the upper shoulder until motion of upper spinous process can be palpated

—Level-Specific Manual Traction

—Place chest against ASIS and upper hip

—Lean toward the patient’s feet

—Use enough force to cause a palpable separation of the spinous processes at a desired level

—

—Unilateral Leg Pull Manual Traction
