Traction
2
Effects of Spinal Distraction
Joint Distraction– Separation of two
articular surfaces– Can treat facet joint &
spinal nerve root symptoms
– Distraction force - 50% of BW for L-spine & 7% for C-spine
3
Effects of Spinal Distraction
Reduction of Disc Protrusion– Suction due to
decreased intradiscal pressure
– Force of 60-120 #’s have been shown to reduce lumbar disc protrusion
4
Effects of Spinal Distraction
Soft Tissue Stretching– Muscles, tendons,
ligaments, discs– Increase soft tissue
length & increase joint mobility
5
Effects of Spinal Distraction
Muscle Relaxation– Can facilitate muscle
relaxationMay be due to
reduction of painMay be due to
prolonged stretch (may fire the GTO)
6
Effects of Spinal Distraction
Joint Mobilization– Stretching of soft
tissues with traction can increase joint mobility
7
Effects of Spinal Distraction
Patient Immobilization– Very low-load traction
(10-20 #’s) has been used to immobilization pts with spinal disorders (Bucks Traction)
– Presently, not as popular
8
Clinical Indications for the Use of Spinal Traction
Disc Bulge or Herniation– Traction may be more beneficial for disc bulge than
herniation– The greater the damage to the disc, the less
effective traction may be.
9
Clinical Indications for the Use of Spinal Traction
Nerve Root Impingement
10
Clinical Indications for the Use of Spinal Traction
Joint Hypomobility– Traction cannot isolate a local area of
hypomobility– Traction can improve mobility throughout the
treated area (c-spine, l-spine)
11
Clinical Indications for the Use of Spinal Traction
Subacute Joint Inflammation– Traction may reduce strain on injured
tissues &/or joints
12
Clinical Indications for the Use of Spinal Traction
Paraspinal Muscle Spasm– Can reduce muscle spasm by reducing by &/or firing
the GTO
13
Clinical Indications for the Use of Spinal Traction
14
Contraindications for the Use of Traction
Where motion is contraindicated– Example – unstable fracture, spinal cord
compression, or shortly after spinal surgery
15
Contraindications for the Use of Traction
With an acute injury or inflammation– Example – shortly after trauma, surgery, RA, OA
16
Contraindications for the Use of Traction
Joint hypermobility or instability– Example – fractures, dislocation, surgery,
pregnancy, lactation, RA, Down’s syndrome
17
Contraindications for the Use of Traction
Peripheralization of symptoms with traction
18
Contraindications for the Use of Traction
Uncontrolled hypertension (for inversion traction)
19
Precautions for the Use of Traction
Structural diseases or conditions affecting the spine(tumor, infection, rheumatoid arthritis, osteoporosis, or prolonged systemic steroid use)
20
Precautions for the Use of Traction
When pressure of the belts may be hazardous (pregnancy, hernia, vascular compromise, osteoporosis)
21
Precautions for the Use of Traction
Displacement of annular fragment– Traction is not likely to change the position
of the fragment
22
Precautions for the Use of Traction
Severe pain relieved by traction– May indicate the spinal nerve root becoming
more compressed as a result of the traction intervention
23
Precautions for the Use of Traction
Claustrophobia
24
Precautions for the Use of Traction
Patients who cannot tolerate the prone or supine position– Pain in prone or supine position or acid
reflux
25
Precautions for the Use of Traction
Disorientation
26
Precautions for the Use of Traction
Temporomandibular joint (TMJ) problems and dentures
27
28
Adverse Effects of Spinal Traction
Worsening of symptoms New symptoms (radiculopathy due to
excessive strain on the spinal cord dura)
29
Application Technique: Mechanical Traction
Mechanical Lumbar Traction Procedure

31
Application Techniques: Self-Traction
Examples of Self-Traction– Sitting Self-Traction– Self-Traction Between
Corner Counters– Self-Traction With
Overhead Bar
32
