Randomized Controlled Trial Comparative Study Clinical Trial
Intrathecal midazolam for the treatment of chronic mechanical low back pain: a controlled comparison with epidural steroid in a pilot study.
This paper describes a prospective, double blind, randomised and dummy-controlled trial in 28 patients with chronic mechanical low back pain presenting to the York Pain Clinic. The therapeutic effects of epidural methyl prednisolone (80 mg) were compared with intrathecal midazolam (2 mg). All the patients had pain for a considerable length of time (range: 1-35 years) and all had received previous treatments which had failed. ⋯ However, although the improvement in the two groups was similar, all the patients treated with steroid were either taking more or the same amount of self-administered analgesic medication after their treatment, whereas between one-third and one-half of the midazolam-treated patients took less medication during the 2 month follow-up period. We conclude that intrathecal midazolam is an effective treatment for chronic mechanical low back pain. The mechanism responsible for this effect is discussed.

Pain perception threshold (PPT), maximal pain tolerance (MPT) and pain discrimination of CLBP patients and controls were tested. Pain perception threshold was significantly higher in the patient group for two different pain stimuli (electrical and pressure pain). ⋯ It is concluded that CLBP patients have a decreased sensitivity for experimental pain. Two theories which might explain this decreased sensitivity are discussed.

Back schools have been proved to be one of the most effective methods of treatment for patients with chronic back pain and disability, and almost every physical therapy clinic now offers some form of education to their back patients. This chapter has attempted to establish what basic information should be available to a person dealing with a back injury, and to offer a logical manner of presenting this information.
