Review Case Reports
Sacral stress fractures: an unusual cause of low back pain in an athlete.
A case report of a sacral stress fracture causing low back pain in an athlete. ⋯ Sacral stress fractures should be included in the differential diagnosis of athletes with low back pain, particularly runners and volleyball players. To the authors' best knowledge, this is the first report of a volleyball player with a sacral stress fracture. A review of the literature yielded 29 cases of sacral stress fractures in athletes, mainly runners.

Clinical Trial
The relation between the transversus abdominis muscles, sacroiliac joint mechanics, and low back pain.
Two abdominal muscle patterns were tested in the same group of individuals, and their effects were compared in relation to sacroiliac joint laxity. One pattern was contraction of the transversus abdominis, independently of the other abdominals; the other was a bracing action that used all the lateral abdominal muscles. ⋯ Contraction of the transversus abdominis significantly decreases the laxity of the sacroiliac joint. This decrease in laxity is larger than that caused by a bracing action using all the lateral abdominal muscles. These findings are in line with the authors' biomechanical model predictions and support the use of independent transversus abdominis contractions for the treatment of low back pain.

Randomized Controlled Trial Comparative Study Clinical TrialLong-term effectiveness of bone-setting, light exercise therapy, and physiotherapy for prolonged back pain: a randomized controlled trial.
Chiropractic manipulation and strenuous exercise therapy have been shown effective in the treatment of nonspecific back pain. Bone-setting, the predecessor of modern manual therapies, still survives in some parts of Finland and was compared with a light exercise therapy and non-manipulative, pragmatic physiotherapy in a year-long randomized controlled trial on patients with long-term back pain. ⋯ Traditional bone-setting seemed more effective than exercise or physiotherapy on back pain and disability, even 1 year after therapy.

The present study was carried out to examine possible mechanisms of back muscle dysfunction by assessing a stabilising and a torque-producing back muscle, the multifidus (MF) and the iliocostalis lumborum pars thoracis (ICLT), respectively, in order to identify whether back pain patients showed altered recruitment patterns during different types of exercise. In a group of healthy subjects (n=77) and patients with sub-acute (n=24) and chronic (51) low back pain, the normalised electromyographic (EMG) activity of the MF and the ICLT (as a percentage of maximal voluntary contraction) were analysed during coordination, stabilisation and strength exercises. The results showed that, in comparison with the healthy subjects, the chronic low back pain patients displayed significantly lower (P=0.013) EMG activity of the MF during the coordination exercises, indicating that, over the long term, back pain patients have a reduced capacity to voluntarily recruit the MF in order to obtain a neutral lordosis. ⋯ During the strength exercises, the normalised activity of both back muscles was significantly lower in chronic low back pain patients (P=0.017 and 0.003 for the MF and ICLT, respectively) than in healthy controls. Pain, pain avoidance and deconditioning may have contributed to these lower levels of EMG activity during intensive back muscle contraction. The possible dysfunction of the MF during coordination exercises and the altered activity of both muscles during strength exercises may be of importance in symptom generation, recurrence or maintenance of low back pain.

Treatment for chronic low back pain in primary care has a poor-quality outcome. There is evidence that multimodal therapy is the most successful approach to its management. We tried to evaluate whether giving primary care physicians evidence-based recommendations on therapy of chronic back pain or directly implementing a multimodal program would improve the outcome of patients with low back pain treated in primary care. ⋯ Giving primary care physicians information on the therapy recommended for treatment of low back pain does not lead to any change in physicians' preferred therapy. Multimodal programs for treatment of chronic low back pain should be organized locally, with existing health care providers joining forces to improve the quality of outcome in chronic low back pain managed in primary care.
