Clinical Trial
Minimal clinically important difference for pain on the VAS scale and the relation to quality of life in women with endometriosis.
The minimal important difference can be helpful in interpreting data from clinical trials. The objective of the study was to calculate the minimal important difference for improvement on the VAS scale for women with endometriosis. ⋯ If the patients have a pain level of at least 50mm on VAS scale at inclusion, the cut off for success in clinical trials is suggested to be defined as an either >40mm or a >50% decrease on VAS scale. Trial registry ClinicalTrials.gov Identifier: NCT01329796.

Chronic migraine (CM) is a highly debilitating disease, and many patients remain refractory to medicinal therapy. Given the convergent nature of neuronal networks in the ventral posteromedial nucleus (VPM) and the evidence of sensitization of pain circuitry in this disease, we hypothesize CM rats will have increased VPM neuronal firing, which can be attenuated using occipital nerve stimulation (ONS). ⋯ We demonstrate that neuronal spike frequencies and bursting activity in the VPM are increased in an animal model of CM compared to shams. Our results suggest that the mechanism of ONS may involve attenuation of neurons in the VPM of CM rats during the application of mechanical stimuli.

Reliability and validity study of the Gujarati version of the Oswestry Disability Index 2.1a.
Among all musculoskeletal disorders back pain is the most common reason for functional limitation in working age. It is due to low back pain (LBP) that the ODI has become one of the principal outcome measures for evaluation of disability and has been widely used in research as well as in clinical practice. So far, validated Gujarati version of the ODI 2.1a has not been reported. ⋯ The Oswestry disability index version 2.1a was successfully translated into Gujarati language, showing excellent psychometric properties. Therefore, it can be used in evaluating the disability amongst Gujarati population with LBP for both clinical and research purposes.

Clinical TrialKnee pain and related health in the community study (KPIC): a cohort study protocol.
The incidence, progression and related risk factors for recent-onset knee pain (KP) remain uncertain. This study aims to examine the natural history of KP including incidence and progression and to identify possible phenotypes and their associated risk factors. ⋯ Baseline data will be used to examine risk factors for early onset KP and to identify KP phenotypes. Subsequent prospective data, at least to Year 3, will allow examination of the natural history of KP and risk factors for incidence and progression.

Prevalence and predictors of persistent pelvic girdle pain 12 years postpartum.
Pelvic girdle pain (PGP) is not always a self-limiting condition. Women with more pronounced persistent PGP (PPGP) report poorer health status compared to women with less pronounced symptoms. The knowledge concerning the long-term consequences of PPGP is limited, thus more knowledge in this area is needed. The overall aim was to study the prevalence and predictors of PPGP 12 years after delivery. ⋯ This study is unique as it is one of few long-term follow-up studies following women with PPGP of more than 11 years. The results show that spontaneous recovery with no recurrences is an unlikely scenario for a subgroup of women with PPGP. Persistency and/or duration of pain symptoms as well as widespread pain appear to be the strongest predictors of poor long-term outcome. Moreover, widespread pain is commonly associated with PPGP and may thus contribute to long-term sick leave and disability pension. A screening tool needs to be developed for the identification of women at risk of developing PPGP to enable early intervention.
