Hyperalgesia and allodynia are typical signs of neuropathic pain. Quantitative sensory testing (QST) is a validated tool to clinically assess these phenomena. However, whether QST reveals findings that are reported by the patients is unclear. The aim of this study was therefore to investigate the association between self-reported symptoms assessed with the painDETECT questionnaire (PDQ) with results of validated QST. ⋯ Results demonstrate that self-reported PDQ symptoms cannot predict abnormal QST values. The poor predictive power of the PDQ may depend on several factors based on possibility of comparison between PDQ and QST and also on methodical issues. Both, symptoms (questionnaires) and signs address complementary aspects of the pain experience and should be considered for diagnosis and treatment of neuropathic pain.

The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) was developed in 2007, including the five domains of Pain-related disorder, Lumbar spine dysfunction, Gait disturbance, Social life disturbance, and Psychological disorder. It is used by physicians to evaluate treatment efficacy by comparing scores before and after treatment. However, the JOABPEQ does not allow evaluation of the severity of a patient's condition compared to the general population at a single time point. Given the unavailability of a standard measurement of back pain, we sought to establish reference scores and interquartile ranges using data obtained from a multicenter, cross-sectional survey taken in Japanese primary care settings. ⋯ Reference scores and interquartile ranges for JOABPEQ were generated based on the data from the examination data. These provide a measurement standard to assess patient perceptions of low back pain at any time point during evaluation or therapy.

Recommendations for Evaluation and Management of Pain in Patients With Mucopolysaccharidosis in Latin America.
The mucopolysaccharidosis (MPS) constitutes a heterogeneous group of rare genetic disorders caused by enzymatic deficiencies that lead to the accumulation of glycosaminoglycans. Several types of MPS are described, historically numbered from I to IX. Clinical observations strongly suggest the presence of chronic pain in patients with all types of MPS. ⋯ Patients with MPS present joint, bone, and muscle pain, as well as entrapment syndromes (spinal, optic nerve, carpal tunnel). The panel suggests the use of the following instruments for pain assessment: Face, Legs, Activity, Cry and Consolability Scale for children of up to four years of age and patients unable to communicate their pain; Child Health Assessment Questionnaire Scale; Facial Pain Scale and Numerical Pain Scale for patients of five to <18 years of age; Brief Pain Inventory and Short Form Health Survey 36 scales for patients aged 18 years or older. Based on the scores verified in these scales, the panel proposes pharmacological interventions for pain relief in this population of patients.

Observational Study
How Much Pain Is Significant? Defining the Minimal Clinically Important Difference for the Visual Analog Scale for Pain After Total Joint Arthroplasty.
The ability to detect changes in patient-perceived pain after total joint arthroplasty (TJA) is critical to manage postoperative pain. The minimal clinically important difference (MCID) for visual analog scale for pain (VAS-P) has not been investigated in this population. This study investigated the MCID for VAS-P in the TJA population. ⋯ In the postoperative TJA population, VAS-P MCID changes depend on the type of surgical intervention, and whether pain is improving or worsening. Statistically significant VAS-P, improving -18.6 mm and -22.6 mm for THA and TKA patients, respectively, sets a reasonable threshold to identify clinically meaningful pain intervention with high specificity.

To explore feasibility of recruitment and retention of runners with patellofemoral pain (PFP), before delivering a step rate intervention. ⋯ Recruitment and retention of a mixed sex PFP cohort to a step rate intervention involving detailed biomechanical measures is feasible. There are indications of both likely efficacy and associated mechanisms. Future studies comparing the efficacy of different running retraining approaches are warranted.
