Mechanical traction can be used for patients with cervical and lumbar spinal disorders such as cervical radiculopathy or lumbar spinal stenosis. Lumbar traction has been widely used in the clinic, previous meta-analyses have confirmed that mechanical traction in the supine position can relieve short-term pain in patients with radiculopathy.

The first time anyone tries inversion therapy with gravity, they should be sure to have someone standing by, in case assistance is required to get out of the apparatus, or if health problems are experienced. [1] During an episode of acid reflux, small amounts of stomach acid may manage to escape from the stomach and into the oesophagus.
Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).
Halo-gravity traction (HGT) is a type of traction device utilized to treat spinal deformities such as scoliosis, [1] [2] congenital spine deformities, cervical instability, basilar invagination, and kyphosis. [3] It is used prior to surgical treatment to reduce the difficulty of the following surgery and the need for a more dangerous surgery.
The latter may be body forces (such as gravity or magnetic attraction), that act throughout the volume of a material; [16]: 42–81 or concentrated loads (such as friction between an axle and a bearing, or the weight of a train wheel on a rail), that are imagined to act over a two-dimensional area, or along a line, or at single point.
Stresses in a contact area loaded simultaneously with a normal and a tangential force. Stresses were made visible using photoelasticity.. Contact mechanics is the study of the deformation of solids that touch each other at one or more points.
In physics, a body force is a force that acts throughout the volume of a body. [1] Forces due to gravity, electric fields and magnetic fields are examples of body forces. Body forces contrast with contact forces or surface forces which are exerted to the surface of an object.
The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...
