The current study examined the validity and reliability of a new system that was developed to measure lumbar region passive stiffness and end range of motion during a trunk lateral bending movement in vivo. Variables measured included force, end range lumbar region motion, torque, lumbar region stiffness, and passive elastic energy. Validity of the force measurements was examined using standard...

OBJECTIVES To investigate the usefulness of a back care education programme on the promotion of knowledge and behaviour of fifth-grade elementary schoolchildren in terms of reducing risk factors for low back pain later in life. METHODS Multi-stage random sampling was used to classify the pupils in one of the intervention or control groups. A validated questionnaire was filled out by each subj...

Exposure to whole-body vibration is a risk factor for the development of low back pain. In order to develop a fuller understanding of the response of the seated person to vibration, experiments have been conducted in the laboratory investigating the biomechanics of the seated person. Some of these methods are based on the driving force and acceleration at the seat and are reported in the litera...

OBJECTIVES The postgraduate educational programme for occupational physicians on guidelines for work rehabilitation of patients with low back pain was evaluated as to what extent did knowledge of the guidelines increase, and did the workers improve their performance at work. METHODS An experimental group (n=25) attended an educational programme and a reference group did so (n=20) 6 months lat...

The caudal approach to the epidural space was first reported in 1901. Injection of steroids to treat low back pain was introduced in 1952. Caudal epidural steroid injection is a safe, effective technique when performed with appropriate care under fluoroscopic visualization. Caudal epidural injections are associated with inaccurate needle placement when performed blindly in a substantial number ...

BACKGROUND It is challenging to interpret the results of multifaceted interventions due to complex program theories that are difficult to measure in a quantifiable manner. The aims of this paper were, first, to develop a model for a comprehensive quantitative implementation evaluation and, second, to operationalize it in the process evaluation of the stepped-wedge cluster randomized controlled ...

INTRODUCTION In France, most studies of low back pain (LBP) have been carried out among workers or patients. Until very recently, the frequency of LBP in the general population was not known, because National Health Surveys did not include questions on LBP. OBJECTIVE To estimate the prevalence of LBP in the French population aged 30 to 64 years. MATERIALS AND METHODS The main data were from...

BACKGROUND Ergonomic factors predispose nurses to low back pain (LBP). Few studies have clarified the role of workplace violence in LBP occurrence. OBJECTIVES The present study was designed to investigate acute and chronic LBP in Iranian nurses and its association with exposure to physical violence as well as its personal and ergonomic risk factors. MATERIALS AND METHODS In this analytic cr...
