Background and Aim: Osteoarthrosis is a common condition in the cervical region due to the high mobility of this region. Despite the clinical popularity of traction that is often prescribed for patients with neck pain, there is no agreement on the effectiveness of traction. Due to the high controversy and the lack of experimental documents in the efficiency of the pneumatic traction device in reducing symptoms of neck pain, present study was conducted to evaluate the efficacy of the pneumatic traction device in reducing pain and amount of drug use, and improving disability level in patients with neck osteoarthrosis compared to the control group. Materials and Methods: Twenty-six patients with neck pain aroused by osteoarthrosis were randomly assigned into two groups of control or experimental. The control group received hot pack, TENS, US, exercise therapy and ergonomic training as their usual physical therapy care. Patients in the experimental group also benefited from the sustained traction via the pneumatic traction device too. All participants were treated for 10 sessions. Pain (NPRS), the level of disability (NDI), the number of sedative drugs and NSAIDs were evaluated in the beginning of the first session and at the end of the last session. Results: A significant decrease in the levels of the pain and disability in both groups were found (P<0.05). The decrease of pain and disability in the experimental group was significantly higher (P<0.05) than the control group. There was no significant difference in terms of the sedatives and NSAIDs within and between the groups at the end of the last session (P>0.05). Conclusion: Although physical therapy and ergonomic trainings may lead to a significant improvement in neck pain and related disability in the osteoarthrosis patients, the use of pneumatic traction device can increase the rate of improvement.
