Fibromyalgia (FM) is recognized as a common condition, characterized by widespread pain and associated with sleep disturbances and poor-quality sleep. The Pittsburgh Sleep Questionnaire Index (PSQI) is one of the most recommended instruments to measure sleep quality and sleep disorders. The purpose of our study was to translate the questionnaire into Spanish and to assess the psychometric properties of the Spanish version of the PSQI. ⋯ A two-factor structure was generated by exploratory factor analysis, with a Cronbach's alpha of 0.866 for factor 1 and of 0.712 for factor 2. In convergent validity analysis, the PSQI total score showed a significant correlation (p < 0.01) with the FIQ total score and with the mental and physical health summaries scores of the SF-36. Our results show that the Spanish version of the PSQI provides a reliable instrument, with a good convergent validity for measuring sleep quality among Spanish FM patients.

To evaluate the effects of therapeutic exercise on pain, stiffness, quality of life, physical function, disease activity, health-related fitness and cardiovascular risk factors in adults with spondyloarthritis (SpA). Electronic databases (Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE/PubMed, PEDro, AMED, CINAHL) were systematically searched from inception to October 2013 using medical subject headings and keywords. This was supplemented by searching conference abstracts and a hand search of reference lists of included studies. ⋯ The addition of aerobic components to flexibility programmes improves cardiorespiratory outcomes, but not cardiovascular risk factors. The most effective exercise protocol remains unclear. Current evidence suggests that therapeutic exercises are beneficial for adults with ankylosing spondylitis; effects on other SpA subtypes are unknown.

Ultrasound evaluation of greater trochanter pain syndrome in patients with spondyloarthritis: are there any specific features?
Although greater trochanter pain syndrome (GTPS) is a prevalent cause of musculoskeletal pain in the general population, there is lack of imaging studies searching for differential features of inflammatory enthesitis in GTPS. We analyzed the features of GTPS using sonography and magnetic resonance imaging (MRI) to identify useful differential signs between spondyloarthritis (SpA) and other inflammatory or non-inflammatory musculoskeletal diseases. All patients with unilateral GTPS attended by our Arthritis Unit between February 2011 and March 2012 were included. ⋯ MRI confirmed the changes detected by ultrasound in all 40 patients evaluated. GTPS in patients with SpA has similar sonographic findings to those observed in patients with RA and patients without musculoskeletal inflammatory disease. Neither sonography nor MRI was clinically useful in classifying GTPS as a manifestation of SpA.
