STUDY DESIGN This was a pilot, cross-sectional study. Its site was West China Hospital in Chengdu, Sichuan Province. OBJECTIVE An objective was to explore whether, in China, chronic low back pain (cLBP) characteristically is one symptom among co-occurring subjective symptoms. More basic objectives were to test a supplemented list of symptoms and to reconfigure findings from the literature on ...

A general method for deriving backpropagation algorithms for networks with recurrent and higher order networks is introduced. The propagation of activation in these networks is determined by dissipative differential equations. The error signal is backpropagated by integrating an associated differential equation. The method is introduced by applying it to the recurrent generalization of the feed...

This study assessed the prevalence of low back pain (LBP) and investigated risk factors for LBP among seafood processing factory workers in Thailand including migrant workers. The subjects were Thai and Myanmar workers in the typical seafood processing factory. A cross-sectional study was carried out with a self-administered questionnaire. Prevalence of LBP, general characteristics, life style,...

This study examines the patterns and determinants of chronic low back pain over a three-year period among older adults in Japan. We tested our model based on a sociomedical perspective, using a two-wave national probability sample survey of persons aged 60 and older (N = 2,200) conducted in 1987 and 1990 in Japan. At baseline, the prevalence of chronic low back pain was 18 percent. Among those ...

OBJECTIVE To evaluate the effectiveness of acupressure in terms of disability, pain scores, and functional status. DESIGN Randomised controlled trial. SETTING Orthopaedic clinic in Kaohsiung, Taiwan. PARTICIPANTS 129 patients with chronic low back pain. INTERVENTION Acupressure or physical therapy for one month. MAIN OUTCOME MEASURES Self administered Chinese versions of standard outc...

This study examined the relationship between perceived (stated) levels of function and the measured (observed) performance in squatting and stair climbing activities of 20 patients with chronic low back pain (CLBP) and 20 healthy volunteers. Subjects were asked through an interview to self-assess their ability to comfortably perform stair climbing and squatting as well as other tolerances. The ...

This commentary explores the importance of considering the biopsychosocial model and contextual factors when prescribing exercise. Diverse exercise programs for patients with chronic low back pain (CLBP) produce similar outcomes, without one specific exercise protocol demonstrating clear superiority. One clear barrier to positive outcomes is poor exercise adherence. We suggest that there are ce...

BACKGROUND Transcranial direct current stimulation (tDCS), applied to the left dorsolateral prefrontal cortex (DLPFC) has been found to improve working memory (WM) performance in both healthy and clinical participants. However, whether this effect can be enhanced by cognitive activity undertaken during tDCS has not yet been explored. OBJECTIVE This study aimed to explore whether tDCS applied ...

Because of the nonlinearity of the Einstein equations, the cosmological fluctuations which are generated during inflation on a wide range of wavelengths do not evolve independently. In particular, to second order in perturbation theory, the first order fluctuations back-react both on the background geometry and on the perturbations themselves. In this paper, the gravitational back-reaction of l...

DURING an investigation into the cause and treatment of eclampsia, it was noticed that there was an appreciable difference between the blood pressure when the patient was on the back and that taken when on the side. When this had been noticed several times, a routine was developed in order to determine whether this difference was constant at all times, and with different patients. At the end of...
