Understanding The Different Types of Lumbar Traction
Lumbar Traction occurs when the back vertebrae are subjected to extending force through body weight, pulley-blocks, and weights to distract private joints of the back spine. During the 1950s and ’60s, James Cyriax propagated lumbar traction as a feasible treatment alternative for disc protrusions, which has shown efficient up until today, treating patients with leg and back pain.

Why Lumbar Traction Is Important
Medically Relevant Anatomy
The back spinal column includes five various vertebrae numbered L1 to L5, which develop the concave lumbar shape in your lower back. The lumbar vertebrae are listed below the thoracic vertebrae in the thorax and are above the sacrum and coccyx. These vertebrae offer upper body weight assistance while enabling motion and versatility to the trunk area. They likewise secure the spine and fragile nerves in the vertebral canal.
The lumbar vertebrae are the heaviest and biggest vertebrae in the spine, 2nd just to the sacrum. The vertebral body– a cylinder of bone– makes up most of the lumbar vertebrae’s mass, and carries the body’s weight.
Types of Lumbar Traction
* Constant Traction– Likewise known as bed traction, this type of traction uses low weights for an extended duration of time (a number of hours at a time). It is commonly believed that constant traction isn’t effective when it comes to separating spinal structures.
* Sustained Traction– Likewise called fixed traction, Continual traction involves utilizing much heavier weights that are applied gradually for a short while (variety from a couple of minutes to an hour).
* Intermittent Mechanical Traction– This traction is the same as sustained traction with regard to period and strength. The only difference is that it utilizes a mechanical unit to apply and launch traction force at intervals.
* Handbook Traction– This type of traction is applied when a belt and/or the clinician’s hands are used to pull the legs of the client. It can be applied as a fast and sudden thrust or applied for a number of seconds.
* Autotraction– This traction utilizes a specifically developed table that’s divided into two parts that can be turned and slanted individually. An individual applies traction force by pushing with the feet and/or pulling with the arms. Research into autotraction has reported favorable scientific results however no alteration in place or size of disc herniation.
* Positional Traction– This traction is used when the patient is placed in different positions using sandbags, obstructs, or pillows to effect a lengthwise pull on the spinal structures. It normally consists of lateral flexing and affects one section of the back segment.
* Gravity lumbar traction– This kind of traction requires utilizing a chest harness to appropriately secure the client given that the table will be slanted to a vertical angle. This utilizes the lower half of the bodyweight to provide traction force.
System of Action
There have actually been multiple theories brought forward explaining the possible clinical advantages of traction therapy. Interfering with the movement area is thought to modify the nucleus pulposus position relative to the annulus fibrosus or modify the disc-nerve user interface. These effects are credible based on research taking a look at the kinematics of the back spinal column with regard to traction therapy. Besides separating the vertebrae, lumbar traction has actually been revealed to decrease nucleus pulposus pressure, and increase the foraminal location. Even so, it’s extremely unlikely that any mechanical modifications seen in a susceptible position will be sustainable after the stated specific resumes an upright, weight-bearing position.
Any enduring action to traction treatment would mostly be due to the effect of traction on the mechanobiology of the neural tissues or motion sector. To make things even more complicated, not all traction therapies use the very same force on the back structures. Animal research studies have actually indicated that the mechanobiology of the disc is sensitive to period, frequency, and amount of loading.
It’s likely that some types of traction trigger joint or disc repair while others stimulate tissue destruction. While these variables haven’t been clinically analyzed (even in animal research studies), the unknown info about disc and joint mechanobiology must notify us that not all types of traction treatments are the same.
