In this study, we evaluated the efficacy of transcranial motor-evoked potentials (tc-MEPs), compared with segmental spinal cord-evoked potentials (SCEPs), for detecting spinal cord ischemia (SCI) and assessed the relationship between neurological outcome and tc-MEPs or SCEPs in the rat aortic occlusion model. In the rats, SCI was induced by aortic occlusion for 10 min with a balloon catheter. At first, tc-MEPs (Group A: n = 6) or segmental SCEPs (Group B: n = 6) was recorded during SCI. ⋯ P50(MEP) obtained in the quantal analysis was 0.3 +/- 0.1 min. P50(SCEP) was calculated as 6.2 +/- 0.5 min that was significantly (P < 0.01) longer than P50(MEP). Our data indicated that tc-MEP monitoring could detect the onset of SCI so rapidly in comparison with segmental SCEP monitoring, which could provide therapeutic windows in a surgical approach that includes spinal cord protection.

Lumbar spondylolysis (LS) has been the subject of several studies focusing on adolescent athletes. Few, if any, studies have examined LS in the general population. Lysis of the pars interarticularis of the vertebra may be associated with slipping (olisthesis), or it may be stable. ⋯ The prevalence of LS increases throughout life and is apparently not a condition restricted to adolescence. Although the cross-sectional nature of the present study prevents an exact estimate of the age at onset; future, sequential studies of the cohort may provide us with some important answers on this topic. Apart from aging-obesity, lordotic angle and pelvic inclination were found to be individual risk factors for LS.

This study aimed to identify current NHS physiotherapy practice following first time lumbar discectomy in the United Kingdom (UK) in order to inform future research priorities and design. Descriptive survey methodology was utilised employing a postal questionnaire. A total population sample was identified and questionnaires were posted to 87 NHS physiotherapy departments throughout the UK. ⋯ There is evidence to support rehabilitation classes to assist early improvements in function and return to work but such classes are only available in around half of the centres involved in this study. Regarding the content of exercise classes and individual treatment sessions, a wide range of clinical practice was evident. This study raises many research questions and highlights the need for future research to optimise patient rehabilitation following first time lumbar discectomy.

The possible effects of back education on children's back function were never evaluated. Therefore, main aim of the present study was to evaluate the effects of back education in elementary schoolchildren on back function parameters. Since the reliability of back function measurement in children is poorly defined, another objective was to test the selected instruments for reliability in 8-11-year olds. ⋯ For leg muscle capacity and spinal curvature no intervention effects were found. The small samples recommend cautious interpretation of intervention effects. However, the present study's findings favor the implementation of back education with focus on postural dynamism in the class as an integral part of the elementary school curriculum in the scope of optimizing spinal loading through the school environment.

Within the scope of primary prevention regarding back functioning in children, research on the stability of intervention effects is indispensable. Along this line, the transition from childhood to adolescence is an important phase to evaluate the potential stability of intervention effects because of the typically mechanical and psychological demands related to adolescence. The main aim of the current study was to investigate the effects of a back education program at 2-year follow-up, in youngsters aged 13-14 years, on back posture knowledge, fear-avoidance beliefs and self-reported pain. ⋯ Based on self-reports for postural behavior, youngsters who had received the back posture program in the elementary school curriculum integrated crucial sitting and lifting principles conform to biomechanical favorable postural behavior. The steady intervention effects 2-year post-intervention demonstrated that intensive back posture education through the elementary school curriculum is effective till adolescence. Future research on the impact of early school-based back posture promotion in relation to the integration of back posture principles according to a biomechanical favorable lifestyle and back pain prevalence later in life is essential.
