Neck Traction DevicesThey are used to overcome neck pain caused by strain, physical stress or injuries. Neck traction device stretches the muscles and joints slightly. This gives more space for nerve roots. It relieves the neck muscles and increases the range of motion. Thus by using neck traction device one can improve the posture. Neck traction devices are available in various forms. Decision regarding their selection is based upon age weight and medical condition of the patient. Air pressure operated neck traction devices: One example of neck traction device makes use of air pressure. It consists of a collar and a inflation bulb to introduce air in it. Air introduction stretches the neck muscles in vertical direction to relieve pressure in the neck. Neck traction device elongates and relieves intra-vertebral disc pressure. How to use neck traction device operated on neck pressure? In the beginning Neck traction devices are used once in a day with a low pressure and for 5-10 minutes. After some days pressure can be increased and use time may be increased up to 20-25 minutes. Gravity operated neck traction devices: Neck traction can also be done by gravity operated devices e.g. ergonomically designed pillow. Here head due to its weight try to go down beyond the support and it pulls the neck. Some designs of neck traction pillow can be used while sleeping also. Weight and Belts: They are using belt to support head on one end of the rope. Rope passes over the support with a weight on other end adjusted accordingly. There are two types of neck traction skin and skeletal. In skin traction counterbalance force is used. It is used for low pressures and temporary use. Skeletal traction uses higher weights and preferred for regular use. Motor operated traction device: Here DC motor worm shaft assembly is used to reciprocate rocker arm. It causes the horizontal pull rod to move and to cause the neck traction. |
