Pain assessment and proper evaluation of pain are prerequisites for treatment of acute and chronic pain. Until now, most evaluations have used only resting pain intensity and a unidimensional scale, although multidimensional pain assessment and especially assessment of functional pain impact on activities are recommended. The Defense and Veterans Pain Rating Scale (DVPRS) permits this multidimensional assessment, but no validated French translation exists. ⋯ The study confirms that the French translation of the DVPRS (the FPS) is a valid measurement instrument for acute and chronic pain evaluation in a wide range of patient groups and is easy for patients to use.

Multicenter Study
Normality Analysis of Numeric Rating Scale Scores in Patients with Chronic Axial Spine Pain Before and After Medial Branch Blocks: a Multicenter Study.
The statistical analysis typically used to compare pain before and after interventions assumes that scores are normally distributed. The present study evaluates whether numeric rating scale (NRS) scores, specifically NRS-11 scores, are indeed normally distributed in a clinically relevant cohort of adults with chronic axial spine pain before and after analgesic intervention. ⋯ Although the results of parametric analyses of NRS-11 scores are commonly reported in pain research, some properties of the NRS-11 do not satisfy the assumptions required for these analyses. The data demonstrate non-normal distributions in post-intervention NRS-11 scores, thereby violating a key requisite for parametric analysis. We urge pain researchers to consider appropriate statistical analysis and reporting for non-normally distributed NRS-11 scores to ensure accurate interpretation and communication of these data. Practicing pain physicians should similarly recognize that parametric post-intervention pain score statistics might not accurately describe the data and should expect articles to utilize measures of normality to justify the selected statistical methods.

Randomized Controlled Trial
Effects of motor imagery using virtual reality on pain sensitivity and affect in healthy individuals: A prospective randomized crossover study.
Exercise induces a hypoalgesic response and improves affect. However, some individuals are unable to exercise for various reasons. Motor imagery, involving kinesthetic and visual imagery without physical movement, activates brain regions associated with these benefits and could be an alternative for those unable to exercise. Virtual reality also enhances motor imagery performance because of its illusion and embodiment. Therefore, we examined the effects of motor imagery combined with virtual reality on pain sensitivity and affect in healthy individuals. ⋯ The study was enrolled in the UMIN Clinical Trials Registry (registration number: UMIN000046095).

Subacromial pain syndrome (SAPS), the most common cause of shoulder pain, can be treated through different treatments with similar effects. Therefore, in terms of deciding on the right treatment fit, patient preferences need to be understood. We aimed to identify treatment characteristics that delineate interventions (attributes) and corresponding sets of specific categorical range (attribute-levels) for SAPS. ⋯ This study identified attributes and attribute levels for the treatment of SAPS. There was a discrepancy in the frequency of the represented attributes between the literature and interviews. This study may improve the understanding of patient preferences for the treatment of SAPS and help individualize care. Our study informs a future discrete choice experiment and supports shared decision-making in clinical practice.
