ReviewPrevention of low back pain: basic ergonomics in the workplace and the clinic.
Redesigning the job is a strategy for preventing low back injuries at work or for accommodating injured employees who return to work. An evaluation of the physical job demands is necessary in either strategy. Several job demands are associated with low back pain and injury--heavy physical work, static or postural effort, dynamic work-load and exposure to wholebody vibration. ⋯ A health care provider should be part of a task force that oversees these interventions. Future effort should be directed to finding a method that health care practitioners could be competent to carry out effectively in a clinical setting. Expert systems offer promising results in disseminating ergonomic knowledge in primary and secondary health care facilities.

Low-back pain and back injuries are of such a complex nature that any one criterion cannot be applied by itself to give a valid assessment of the risk associated with manual materials-handling jobs. There is no question that low-back pain is an extremely significant cause of disability and has a major socioeconomic impact, but many different personal and job factors are associated with the incidence and prevalence of these complaints. There is a need for ongoing systematic investigations of the multiple risk factors that may be causally related to low-back pain and may possibly be amendable to preventive interventions. ⋯ If, however, such lifting is performed repetitively, the medical hazard extends beyond low-back problems to other musculoskeletal strain and sprain injuries and to fatigue-related injuries, particularly for weaker workers. In this latter regard, gender, age, anthropometry, and previous history of back pain are known to modify these risks for populations of workers. The inherent variability between workers and within any worker over time precludes the use of such factors to assign risk to any particular individual.

Back and leg pain in patients with lumbar disc herniation can be caused by various mechanisms. In addition to nerve root compression, functional alterations in the sacroiliac joint, facet joint or the iliolumbar and sacrotuberal ligaments can produce "pseudoradicular" lower back syndrome. The following study attempts to show whether or not pain and functional alterations in the sacroiliac joint (SIJ) correlate with herniations revealed by computed tomography (CT). ⋯ Frequency of SIJ tenderness is significantly higher in patients with herniations between L5 and S1. Since the SIJ is innervated by the r. dorsalis of the sacral roots, the increased tenderness can be explained by the change in neurovegetative innervation of the SIJ. Due to the high correlation between lumbar disc herniation and SIJ dysfunction, disc herniation should be considered as a possible cause of sacroiliac-joint syndrome.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA controlled, multicentre trial of manual therapy in low-back pain. Initial status, sick-leave and pain score during follow-up.
101 outpatients with acute or subacute low-back pain were randomly allocated to one of two treatment groups. One group was given standardized conventional but optimal activating treatment by primary health care teams. The other group received manual treatment such as manipulation, specific mobilization, muscle stretching, auto-traction, and cortisone injections. ⋯ The difference diminished over time but was still significant after eight months. Two slightly different pain scores ("pain at the moment" and "pain during the last weeks"), initially similar in the two groups, diminished in both groups but were significantly lower in the manual treatment group during the study. The group receiving specific manual treatment thus had a significantly better outcome than the group receiving conventional treatment as far as sick-leave and pain score are concerned.

A patient underwent outpatient knee arthroscopy with spinal anesthesia administered at the patient's request. The patient was discharged after a 3-hour recovery period. Three days later, the patient returned because of a headache that had begun the evening after surgery and progressively worsened. ⋯ Therapy with aspirin 600 mg 4 times daily resulted in acute and significant relief. The backache resolved after 1 week. A review of the literature on backache following epidural blood patch is presented.
