M.Tech. (Chiropractic) / Purpose: The aim of this study was to look at the effectiveness of massage with MYO₂ gel in conjunction with Spinal Manipulative Therapy (SMT) for the treatment of patients with posterior mechanical neck pain, with regards to pain, disability and cervical spine range of motion. The effect of these treatments was evaluated using a questionnaire consisting of Visual Analogue Scale (VAS) and a Vernon-Mior Neck Pain and Disability Index Questionnaire, and by measuring cervical spine range of motion using a cervical range of motion (CROM) measuring device. Method: 30 participants with posterior mechanical neck pain were randomly divided into two groups based on the order they start the study in. Group A – control group, received SMT to the cervical spine, followed by massage with ultrasound gel over the upper trapezius muscle and the area of the posterior neck musculature. Group B – experimental group, received SMT of the cervical spine, followed by massage with MYO₂ gel over the upper trapezius muscle and the area of the posterior neck musculature. Participants were treated six times out of a total of seven sessions, over a maximum three week period. Procedure: Subjective data was collected at the beginning of the first and fourth and seventh consultations. This was done by means of a Visual Analogue Scale (VAS) and a Vernon- Mior Neck Pain and Disability Index Questionnaire in order to assess pain and disability levels. Objective data was collected at the beginning of the first, fourth session, and seventh consultation by means of measuring cervical spine range of motion using a cervical range of motion (CROM) measuring device. Analysis of collected data was performed by a statistician from STATKON; a department of the University of Johannesburg. Results: When comparing the VAS of the initial with the final consultation it showed a statistically significant difference in both groups. This indicated that both interventions were effective in decreasing the perceived level of neck pain (VAS score). When comparing the Neck Pain and Disability Index of the initial with the final consultation it showed a statistically significant difference in both groups. This indicated that both interventions were effective in decreasing neck pain and disability of the cervical spine. When comparing the Cervical Range of Motion (CROM) of the initial consultation with the final consultation it showed a statistically significant improvement in both groups in all directions of motion. Both groups resulted in an increase in range of motion over time. Group B had a greater average CROM percentage increase of 28.60% average compared to Group A which had an average percentage increase of 22.25%.
