“…Some studies omitted to report the time between the initial clinical assessment and administration of the questionnaire(s) [9-13,22,23,26-29,31-37,[40][41][42][43][44][46][47][48][49][50]. In these cases patients may have changed over time, thus reducing the methodological quality and the robustness of the results on criterion validity.The overall level of evidence of the included studies was low or very low due to the methodological quality and the small sample sizes.…”

“…The questionnaire included a total of 65 questions, which included the Brazilian-portuguese validated questionnaires DN4 7 (Neuropathic Pain in 4 questions), the LANSS 8 (Leeds assessment of neuropathic symptoms and signs), Beck Depression Inventory (BDI) 9 and Anxiety (BAI) 9 , a pain questionnaire and disease related information. The survey was given to each patient at the end of their physician consult to complete independently, with no time constraints.…”

While several studies have found a relationship for the development of pain related to one or more multiple sclerosis (MS) factors such as patient's age, duration of disease, disease course, and disability 1,2,3 , virtually an equal number have not 4,5 . Pain clearly has a role in the disease as its prevalence has been reported ranging up to 74% in MS outpatients 6 . While research does implicate factors that may be related to pain, multivariate analyses are lacking, which leaves the issue unclear as to the role of the various risk factors in the development of pain 6 . The development of MS pain and its severity has implications into the general evolution of the disease which itself varies amongst the different clinical forms [relapsing-remitting-(RR), primary progressive-(PP) and secondary progressive-(SP)] as well as its gender-specific presentation. This study investigates the prevalence and severity of pain amongst multiple variables in attempt to further elucidate the role of pain within the evolution of MS. Our goal is to evaluate these results within the context of the recent mechanisms of MS that have addressed not only gender AbstrActObjective: The study aims to investigate the presence of pain amongst multiple sclerosis (MS) patients. Method: One hundred MS patients responded to questionnaires evaluating neuropathic and nociceptive pain, depression and anxiety. Statistical analysis was performed using the Mann-Whitney U, Chi-Square and two-tailed Fisher's exact tests and multivariate logistic regression. Results: Women had a statistically higher prevalence of pain (p = 0.037), and chances of having pain after the age of 50 reduced. Women with pain had a statistically significant lower number of relapses (p = 0.003), restricting analysis to those patients with more than one relapse. After the second relapse, each relapse reduced the chance of having pain by 46%. Presence of pain was independent of Expanded Disability Status Scale (EDSS) anxiety, and depression. Conclusion: Our findings suggest a strong inverse association between relapses and pain indicating a possible protective role of focal inflammation in the control of pain.Keywords: multiple sclerosis, pain, prevalence, relapses, gender. resumoObjetivo: O estudo tem como objetivo investigar a presença de dor entre pacientes com esclerose múltipla (EM). Método: Cem pacientes com EM responderam a questionários avaliando dor neuropática e nociceptiva, depressão e ansiedade. A análise estatística foi realizada através dos testes de Mann-Whitney U, Qui-Quadrado, two tailed Fisher exact test e regressão logística multivariada. Resultados: As mulheres apresentaram estatisticamente uma maior prevalência de dor (p = 0,037), e as chances de ter dor após a idade de 50 reduziram. As mulheres com dor tinham um número com significância estatística reduzido de surtos (p = 0,003), restringindo a análise aos pacientes com mais de um surto. Após o segundo surto, cada surto reduziu a chance de ter dor em 46%. A presença de dor foi independente da Expanded Disabil...

“…In addition to Portuguese, LANSS scale was translated into Spanish 15 and Turkish 16 . Portuguese version of Brazilian LANSS is considered reliable to be used in clinical practice and research 11 . Due to the need for training to apply LANSS, there could be difficulties to use such tool in some clinical situations and in research 17 .…”

“…To date, seven tools were developed to differentiate NP from non-neuropathic pain, and three more to describe NP 8 . Among ten NP evaluation tools, four were translated and validated to Brazilian Portuguese [9][10][11][12] . This article aimed at describing tools developed for the initial evaluation of NP patients.…”

Brazilian Portuguese Validation of the Leeds Assessment of Neuropathic Symptoms and Signs for Patients with Chronic Pain

Abstract: This LANSS version was found to be a reliable instrument for the evaluation of pain complaints due to a variety of causes. The profile of pain scores was similar to that observed in other countries.
