Title: The effectiveness of an electromechanical adjusting instrumental compared to cervical spine manipulation in the treatment of cervicogenic headaches
Authors: Whittaker, Russell

Background: Cervicogenic headaches are usually chronic, debilitating and tend to be unresponsive to common headache medications. Manual therapy has been shown to be an effective form of management for cervicogenic headache. The Electromechanical Adjusting Instrument is a hand-held device offered as an alternative to manual therapy for musculoskeletal treatment.

Aim: The aim of this study was to determine the effectiveness of the Electromechanical Adjusting Instrument compared to cervical spine manipulation in terms of subjective and objective measures in the treatment of cervicogenic headache.

Methodology: This study was a randomised single-blinded clinical trial. There were 41 participants between the ages of 18 and 59 years who were randomly divided into two groups of 21 and 20 respectively by means of a randomisation table drawn up by the statistician. Participants in Group A received cervical spine manipulation while those in Group B received the Electromechanical Adjusting Instrument. Subjective headache intensity was determined using a Numerical Pain Rating Scale. The effect of neck pain on the participants’ activities of daily living before and after treatment was assessed using the Neck Disability Index. The effect of the headache on the participants’ activities of daily living before and after treatment was assessed using the Headache Disability Index. Objective cervical range of motion in all six planes of motion was assessed using a CROM goniometer. Participants in both groups received six interventions over a three-week period with a minimum interval of 48 hours between each intervention. The subjective and objectives assessments were taken at baseline, post-third and post-sixth interventions. The data was analysed using the IBM SPSS version 24.0. Repeated measures ANOVA was used to examine the effect on each outcome measure separately of time and treatment group interaction. Profile plots were generated to show the rates of changes in outcomes over time by the intervention group. A p value <0.05 was considered statistically significant.

Results: For most of the outcomes, there was no clinical or statistical interaction present, i.e. the intervention effect was similar in both groups irrespective of the intervention.

Conclusion: The trends in each of the outcomes suggest that the Electromechanical Adjusting Instrument is as effective as cervical spine manipulation for the treatment of cervicogenic headache
