Randomized Controlled TrialIs low-level laser therapy effective in acute or chronic low back pain?
The purpose of this study was to compare the effectiveness of low-level laser therapy (LLLT) on pain and functional capacity in patients with acute and chronic low back pain caused by lumbar disk herniation (LDH). LLLT has been used to treat acute and chronic pain of musculoskeletal system disorders. This study is a randomized, double-blind, placebo-controlled study. ⋯ After the treatment, there were statistically significant improvements in pain severity, patients' and physician's global assessment, ROM, RDQ scores, and MODQ scores in all groups (p < 0.05). However, no significant differences were detected between four treatment groups with respect to all outcome parameters (p > 0.05). There were no differences between laser and placebo laser treatments on pain severity and functional capacity in patients with acute and chronic low back pain caused by LDH.

Validity, reliability, and comparison of the WOMAC osteoarthritis index and Lequesne algofunctional index in Turkish patients with hip or knee osteoarthritis.
To assess validity and reliability of the Western Ontario and McMaster Universities (WOMAC) osteoarthritis (OA) index and Lequesne algofunctional index in Turkish patients with hip or knee OA and to compare the results of the instruments for these two particular sites of involvement. Two disease-specific instruments: WOMAC LK 3.1 and Lequesne indices were administered to 117 outpatients with OA (44 hip and 73 knee) living in Turkey. These indices were administered twice 7-10 days apart to ensure the test-retest reliability. ⋯ WOMAC and Lequesne showed moderate-good correlations between comparable subscales of SF-36 (physical functioning and bodily pain) and weak-moderate correlations between VAS. All subscales and total WOMAC had better internal consistency and more satisfactory concurrent validity compared with Lequesne. Our results indicated that WOMAC is a more reliable index for use in Turkish patients with hip or knee OA than Lequesne.

Reliability and validity of the foot and ankle outcome score: a validation study from Iran.
The aims of this study were to culturally adapt and validate the Persian version of Foot and Ankle Outcome Score (FAOS) and present data on its psychometric properties for patients with different foot and ankle problems. The Persian version of FAOS was developed after a standard forward-backward translation and cultural adaptation process. The sample included 93 patients with foot and ankle disorders who were asked to complete two questionnaires: FAOS and Short-Form 36 Health Survey (SF-36). ⋯ For dimensionality, the minimum Spearman's correlation coefficient of 0.40 was exceeded by most items. In conclusion, the results of our study show that the Persian version of FAOS seems to be suitable for Iranian patients with various foot and ankle problems especially lateral ankle sprain. Future studies are needed to establish stronger psychometric properties for patients with different foot and ankle problems.

Evidence for generalized hyperalgesia in chronic fatigue syndrome: a case control study.
Several studies provided evidence for generalized hyperalgesia in fibromyalgia or whiplash-associated disorders. In chronic fatigue syndrome, however, pain is a frequently reported complaint, but up to now, evidence for generalized hyperalgesia is lacking. The aim of this study is to examine whether the pressure pain thresholds (PPTs) at both symptomatic and asymptomatic sites differ in chronic fatigue syndrome (CFS) patients with chronic pain, compared to healthy controls. ⋯ No confounding factors responsible for the observed differences, as, e.g., catastrophizing and depression, could be revealed. These findings provide evidence for the existence of hyperalgesia even in asymptomatic areas (generalized secondary hyperalgesia). The generalized hyperalgesia may represent the involvement of a sensitized central nervous system.
