In reviewing the literature, few traction devices have been investigated and published in the biomedical literature. In a recent study, however, published in JNMS: Journal of the Neuromusculoskeletal System, five home-use supine cervical traction devices were studied to determine their effectiveness in providing separation of the vertebral segments, releasing the musculature, and patient satisfaction. The authors concluded that all of the devices tested were capable of distracting the cervical spine, attaining greater separation at the posterior disc height than anterior. Pronex™ was found to increase the anterior disc height an average of 4.9 mm, and the posterior disc height be 8.4 mm. The greatest change in anterior as well as posterior intervertebral space came for C5-C6, and C6-C7.
Based on the results of the study, in terms of patient satisfaction, Pronex™ was found to be the clear choice among the subjects tested, scoring favorably above all other devices. Another clear advantage of Pronex™ was that it did not place any pressure on the mandible or TMJ which was a complaint amongst other devices which caused extreme pressure on the jaw and forehead.
Our Investigations:

 |
| Prior to Pronex™ | 15 minute follow-up after
Pronex™ traction for 15 minutes |
We performed an investigation into the effectiveness of Pronex™ in vertebral alignment before, during and after a 15 minute traction sessions with the device. It was found that during the traction session, an increase of the normal C2-C7 lordosis of 18 degrees was achieved and an overall height increase from C3-C7 of 6 mm was seen. Follow-up radiographs demonstrated the immediate changes in resting head and neck posture.
With over 100,000 units in use, and endorsements from numerous neurosurgeons, Pronex™ is now recognized as the traction unit of choice for cervical spine rehabilitation and pain management. We feel that the addition of Pronex™ to regimented care plans serves to benefit both the patient and practicing clinician.
