Randomized Controlled Trial Comparative Study Clinical TrialSpinal manipulation vs. amitriptyline for the treatment of chronic tension-type headaches: a randomized clinical trial.
To compare the effectiveness of spinal manipulation and pharmaceutical treatment (amitriptyline) for chronic tension-type headache. ⋯ The results of this study show that spinal manipulative therapy is an effective treatment for tension headaches. Amitriptyline therapy was slightly more effective in reducing pain at the end of the treatment period but was associated with more side effects. Four weeks after the cessation of treatment, however, the patients who received spinal manipulative therapy experienced a sustained therapeutic benefit in all major outcomes in contrast to the patients that received amitriptyline therapy, who reverted to baseline values. The sustained therapeutic benefit associated with spinal manipulation seemed to result in a decreased need for over-the-counter medication. There is a need to assess the effectiveness of spinal manipulative therapy beyond four weeks and to compare spinal manipulative therapy to an appropriate placebo such as sham manipulation in future clinical trials.
