The effect of the chiropractic adjustment with a strengthening protocol compared to chiropractic adjustment or a strengthening protocol alone

M.Tech.OBJECTIVE: The aim of this study was to determine whether adjustment of the cervico-thoracic motion segment in individuals with altered or decreased motion at that segment, in conjunction with a strengthening protocol, had a greater increase in triceps brachii muscle strength compared to a strengthening protocol or chiropractic adjustment alone. By reducing the negative neural and other effects caused by aberrant movement between vertebra, chiropractic adjustment could allow the body’s muscle physiology to function at its best, thereby allowing it to adapt to changes more readily. DESIGN: Thirty subjects participated in this study. The subjects were randomly and without being aware of it, assigned to one of three groups. The only requirement for inclusion in the research was a restriction of the seventh cervical vertebra based on motion and static palpation. Patients in two of the groups were asked to perform tricep brachii muscle strengthening exercises and patients from two of the groups received chiropractic adjustment to the cervico-thoracic motion segment. Patients were seen a total of three times over a period of two weeks. MEASUREMENTS: Triceps brachii muscle strength testing was performed using an isometric dynamometer. Three pre-treatment readings and three post-treatment readings were performed, with one-minute intervals, on all the subjects. This was done to determine if there was a change before or after treatment and if there was a long-term effect. CONCLUSION: Although measurements were taken on each visit before and after each treatment, there was only a statistically significant difference in triceps brachii muscle strength between the experimental and the other two groups before treatment on the third visit. This does however; suggest that there was a favourable result and that a combination of treatments does indeed produce better results than one of the other treatments alone
