cervical traction to treat cervical radiculopathy. Only low quality evidence has been released and the authors of these guidelines encourage researchers to intensify studies on tractions effect on cervical radiculopathy. Researchers have also demonstrated lumbar traction to be advantageous in treating low back pain. Three studies in 2017 confirmed an increase of nutrient and water flow into the intervertebral discs after traction treatment. Purpose The purpose of traction is to: Regain normal length and alignment of involved bone Lessen or eliminate muscle spasms Relieve pressure on nerves, especially spinal nerves Prevent or reduce skeletal deformities or muscle contractures To provide a fusiform tamponade around a bleeding vessel In most cases traction is only one part of the treatment plan of a patient needing such therapy. The physician's order will contain: Type of traction Amount of weight to be applied Frequency of neurovascular checks if more frequent than every four hours Site care of inserted pins, wires, or tongs The site and care of straps, harnesses and halters The inclusion of any other physical restraints / straps or appliances (e.g., mouth guard) The discontinuation of traction Future The variability of traction delivery protocols causes a gap that may be the reason for negative conclusions that traction has no positive effects. A key to the future success of traction may be finding the proper therapeutic dosage levels. Suboptimal dosage choices may be a key for the negative conclusions on traction. Different dosage levels for aspects such as traction force, traction rhythm, duration of treatment, and frequency could be the key to providing efficient effects. Proper dosage levels for any therapeutic treatment will be vital for recovery efficiency. Patients may have a “directional preference” to an axial force which may be an underlying cause for positive results. Future research is needed to discover if directional preference has a positive therapeutic effect within traction.
