Dry needling versus cervical spine manipulation combined with dry needling of infraspinatus muscle myofascial trigger points

M.Tech. (Chiropractic)Objective: The purpose of this study was to compare dry needling with cervical spine manipulation combined with dry needling, in the treatment of infraspinatus muscle myofascial trigger points. Study Design: This was a randomized experimental study Setting: The participants were treated at the University of Johannesburg chiropractic day clinic Subjects: 30 participants volunteered for the study. The participants were divided into groups by randomly drawing thirty numbers from a hat, and placing them into two groups: either dry needling combined with spinal manipulation (group 1) or dry needling only (group 2). Participants had to be between eighteen and fifty years old and they could have been male or female. Participants had to present with active infraspinatus muscle myofascial trigger points and also had to present with shoulder or lateral arm pain reproduced by infraspinatus trigger point palpation. Method: Participants were either treated using dry needling only or dry needling combined with spinal manipulation. There were seven consultations. The first six consultations were treatment consultations. Measurements were taken at consultations one, four and seven. Results: The results indicate statistically that participants who had dry needling on its own had a faster increased pressure pain tolerance and a faster decrease in resting electrical activity of the muscle over the treatment period than those that recieved dry needling in combination with spinal manipulation. We must emphasize however that this did not show in the numerical pain rating scale. Participants felt a relatively even relief of their pain in both groups. These overall results might have been skewed by outliers in groups and a small demographic study size. The rest of the results were statistically insignificant, however there was a clinically desired therapeutic effect noted in both groups throughout the study. Conclusion: Dry needling only and dry needling combined with spinal manipulation, individually have desired therapeutic effects in the treatment of infraspinatus myofascial trigger points. There is however no conclusive statistical results in this study that shows one treatment protocol to have a greater therapeutic effect when compared to the other. However this study size was small and therefore the results may have been coincidental
