Objective. The conventional technique used to stimulate the lumbar dermatomes is by stimulation of the dorsal columns of the spinal cord. Until recently, stimulation of nerve roots had not been successfully accomplished. ⋯ Lumbar and sacral NRS trials resulted in adequate paresthesia coverage and effective pain relief in all 5 patients. Further clinical trials to evaluate long-term success rates and safety are indicated. Detailed mapping studies are needed to evaluate the relationship between electrode placement and paresthesia patterns as well as the optimal stimulation parameters.

Sitting and low back pain: the positive effect of rotary dynamic stimuli during prolonged sitting.
In this study the effect of dynamic stimuli on low back pain during prolonged sitting was investigated. The pain experience of two groups of 60 subjects with a specific low back pain was recorded. ⋯ Two different frequencies of rotation were applied in subgroups. The authors concluded that such stimuli, especially of the lower frequency, reduced pain in prolonged sitting.

Low back pain (LBP) among children and adolescents has become the subject of an increasing amount of literature over the last 15 years. This topic, which was considered almost insignificant less than two decades ago, was the focus of a recent international meeting organised in Grenoble (France) in March 1999. This review paper is the result of an literature update search performed by members of three groups which have been active in this field for many years. Current epidemiological data on LBP is summarized as well as the role of the major risk factors according to studies published in the principal peer reviewed journals interested in the topic.

A study was undertaken to analyse the prevalence of low back pain (LBP) and confounding factors in primary school children in the city of Antwerp. A total of 392 children aged 9 were included in the study. All children completed a validated three-page questionnaire and they all underwent a specific lumbar spine oriented medical examination during their annual routine medical school control. ⋯ The visual analogue scales concerning general well-being were all very significantly correlated with self-reported LBP, with children who reported LBP being more tired, less happy, and worse sleepers. Of the 19 clinical parameters taken down during the medical examination, only one was significantly more prevalent in the group of children reporting LBP: pain on palpation at the insertion site on the iliac crest of the ilio-lumbar ligament. From this study we can establish that there are few clinical signs that can help to single out school children with LBP.

This study was designed as a cross-sectional questionnaire-based survey of low back pain (LBP) in 13- to 16-year-old Danish school children. The cohort consisted of 671 boys and 718 girls in eighth and ninth grade in 46 municipal schools in three counties of Sealand. All the pupils filled in a questionnaire with LBP as the main topic and were at the same time examined by the school doctors. ⋯ This was positively correlated to female gender, BMI more than 25 kg/m(2), competitive sport for boys, poor physical fitness, daily smoking, heavy jobs in leisure time, increased use of the health system and reduced life quality. Stepwise logistic regression analysis indicates that female gender, daily smoking and heavy jobs are important associated factors for severe LBP in adolescents, with an observed probability of 46% if all factors are present. We don't know yet whether these factors are of any causal importance in the development of severe LBP.
