OBJECTIVE To compare the efficacy of surgery with disc prosthesis versus non-surgical treatment for patients with chronic low back pain. DESIGN A prospective randomised multicentre study. SETTING Five university hospitals in Norway. PARTICIPANTS 173 patients with a history of low back pain for at least one year, Oswestry disability index of at least(More)
BACKGROUND The need for cost effectiveness analyses in randomized controlled trials that compare treatment options is increasing. The selection of the optimal utility measure is important, and a central question is whether the two most commonly used indexes - the EuroQuol 5D (EQ5D) and the Short Form 6D (SF6D) - can be used interchangeably. The aim of the(More)
Specific data on different musculoskeletal (MSK) disorders from the Global Burden of Disease (GBD) study will be presented in this 1–3 and future issues of the journal. 4–9 MSK disorders are the second most common cause of disability worldwide , measured by years lived with disability (YLDs), with low back pain being the most frequent condition. 10(More)
BACKGROUND Pain catastrophizing has been found to be an important predictor of disability and days lost from work in patients with low back pain. The most commonly used outcome measure to identify pain catastrophizing is the Pain Catastrophizing Scale (PCS). To enable the use of the PCS in clinical settings and research in Norwegian speaking patients, the(More)
BACKGROUND Non-specific low back pain (LBP) is usually self-limiting within 4-6 weeks. Longstanding pain and disability are not predictable from clinical signs or pathoanatomical findings. Pain cognition and physical performance have been shown to improve patients with chronic LBP following neurophysiological education. The primary aim of this study is to(More)
BACKGROUND Prevalence of musculoskeletal pain among adolescents is high, and pain in adolescence increases the risk of chronic pain in adulthood. Studies have shown conflicting evidence regarding associations between physical activity and musculoskeletal pain, and few have evaluated the potential impact of sport participation on musculoskeletal pain in(More)
BACKGROUND An individualized patient reported outcome (PRO) has recently been recommended within LBP research, but no study has evaluated this instrument with commonly applied PROs. Moreover, the impact of psychological factors has mostly been assessed for disease-specific instruments. The objective of this study was to assess the predictive value of(More)
BACKGROUND Evidence is lacking on whether fat infiltration in the multifidus muscles affects outcomes after total disc replacement (TDR) surgery and if it develops after surgery. The aims of this study were 1) to investigate whether pre-treatment multifidus muscle fat infiltration predicts outcome 2 years after treatment with TDR surgery or(More)
BACKGROUND There are several posterior decompression techniques for lumbar spinal stenosis (LSS). There is a trend towards performing less invasive surgical procedures, but no multicentre randomized controlled trials have evaluated the relative efficacy of these techniques at short and long-term. METHOD/DESIGN A multicentre randomized controlled trial(More)
