Movement-evoked pain is not associated with pain at rest or physical function in knee osteoarthritis.

INTRODUCTION: Knee Osteoarthritis (KOA) is mainly characterized by pain. The assessment of KOA-related pain frequently focuses on different constructs subject to sources of bias or drawbacks, as the classical Pain at Rest (PAR). Movement-evoked pain (MEP), recently defined as 'pain during walking', emerges as a differential concept, since PAR and MEP are driven by different underlying mechanisms. Given the novelty of the MEP approach, its association with PAR or with different performance-based tests has not been studied in KOA yet. MATERIALS AND METHODS: A cross sectional study was conducted. PAR was measured, alongside the performance of four mobility tests and their corresponding MEP: Timed Up and Go Test, 10-metre Walk Test, 2-Minute Walk Test, and 6-Minute Walk Test. Association and agreement were explored for MEP versus PAR, while the correlation of the tests versus each corresponding MEP-measure was assessed. RESULTS: Neither association nor agreement were found in the duality MEP versus PAR. Also, the lack of association between the performance of a mobility test and the perceived level of pain during the development of the test was stated. CONCLUSION: Movement-evoked pain is neither related to pain at rest nor to functional performance in subjects affected by knee osteoarthritis. The results from our study suggest that MEP and pain at rest measure and refer to different constructs in knee osteoarthritis. The implementation of MEP as an outcome in exercise-therapy could enhance the tracking of results, as well as the development of tailored interventions under different conditions. SIGNIFICANCE: This research elucidates the relevance of MEP, recently defined as 'pain during walking', through the analysis of its association with PAR and with functional performance (measured through four mobility tests) in knee osteoarthritis. The results from our study highlight the absence of either association or agreement between MEP and PAR, fact that supports and endorses the idea that both concepts measure and refer to different constructs in knee osteoarthritis.

Family Planning in Fertile-Age Patients With Multiple Sclerosis (MS) (ConPlanEM Study): Delphi Consensus Statements.

Family planning is essential for establishing Multiple Sclerosis (MS) prognosis, treatment decision, and disease monitoring. We aimed to generate an expert consensus addressing recommendations for family planning in MS patients of childbearing age. Initially, a committee comprising seven neurologists, experts in the MS field, identified the topics to be addressed. Then, the committee elaborated on different evidence-based preliminary statements. Next, using the Delphi methodology, a panel of neurologists manifested their level of agreement on the different statements using a Likert-type scale. Consensus was reached when ⩾70% of respondents expressed an agreement or disagreement using a five-point scale. Consensus was achieved on 47 out of 63 recommendations after three rounds of evaluations. The panel considered it essential to address family planning in all patients of childbearing age. There was also consensus that treatment should not be delayed due to the patient's desire for pregnancy. Additionally, in highly active patients, planning the pregnancy in the medium to long term using depletory drugs such as cladribine or alemtuzumab might represent a useful strategy. However, risks of adverse effects on the fetus due to drug-associated secondary autoimmunity should be addressed when alemtuzumab is considered. Moreover, the maintenance of natalizumab during pregnancy in very active patients reached expert consensus. Also, the panel supported the use of certain disease-modifying treatment (DMT) during lactation in selected cases. Our results identified specific areas of pregnancy planning in MS patients, where different treatment strategies might be considered to facilitate a safe and successful pregnancy while maintaining clinical and radiological stability.

Concurrent validity of the 2-and 6-minute walk test in knee osteoarthritis.

BACKGROUND: The 6-Minute Walk Test (6MWT) is frequently used for the assessment of walking distances in several conditions, as knee osteoarthritis, but it can be both time-consuming for the researcher or clinician, and exhausting of painful for the subject suffering from this condition. The objective of our study was to analyze the concurrent validity of the 2-Minute Walk Test (2MWT) for patients with knee osteoarthritis compared to the 6-Minute Walk Test (6MWT). METHODS: Cross-sectional validation study. Scores from the 6MWT of 42 ambulatory patients affected by knee osteoarthritis were compared to those from the shorter 2MWT. An initial correlation test was used to assess correlation between both measures, and a subsequent univariate regression analysis was performed with the aim of comparing the estimated outcomes of the 6MWT versus the actual 6MWT. RESULTS: The scores from the 2MWT and 6MWT showed excellent correlation (Pearson's correlation coefficient r = 0.976; p-value < 0.001); the predictive equation based on the scores from the 2MWT (R2 = 0.952, p-value < 0.001) estimates the 6MWT scores with a relative error of 3.23%. CONCLUSIONS: The 2MWT may be a practical assessment tool in replacement for the 6MWT in clinical assessment due to its low burden on patients and as a means of improving efficiency in a timely manner.

The pain attitudes and beliefs scale for physiotherapists: development and psychometric assessment of the Spanish version among physiotherapy students.

INTRODUCTION: Pain might be approached from a biomedical or biopsychosocial perspective. There is a lack of research on the attitudes and beliefs about pain among physiotherapy students. In this context, the Pain Attitudes and Belief Scale for Physiotherapists (PABS-PT) is an instrument widely used from a clinical and educational perspective, but its psychometric properties have not yet been tested in a student-based population. OBJECTIVE: To develop the Spanish version of the PABS-PT scale and to assess its psychometric properties among students in physiotherapy. METHODS: The study was carried out among 103 students in their final years of academic studies in the Degree in Physiotherapy in the University of Murcia (Spain). Sociodemographic and PABS-PT related variables were collected. The instrument was translated into Spanish and tested through factor analysis, internal consistency, test-retest reliability, and known-groups validity. The 95% minimal detectable change of the instrument was also calculated. RESULTS: The factor analysis revealed two factors within the instrument: Biomedical (9 items) and Biopsychosocial (7 items) factors, with Cronbach's alpha values of 0.730 and 0.708, respectively. The Intraclass Correlation Coefficient (3,2) was 0.851 for the Biomedical factor and 0.699 for the Biopsychosocial factor. The minimal detectable changes (95% CI) for the Biomedical and Biopsychosocial factors were 6.01 and 5.56, respectively. The pre-specified hypothesis for the known-groups validity test was met and revealed large effect sizes (d = 1.24). CONCLUSION: The Spanish version of the instrument PABS-PT-SP covers two factors. It shows satisfactory psychometric properties and it is therefore an effective framework to discriminate between the biomedical and/or biopsychosocial thoughts and attitudes toward pain in physiotherapy.

Addition of tDCS and TENS to an education and exercise program in subjects with knee osteoarthritis: A study protocol.

BACKGROUND: Knee osteoarthritis often leads to chronic pain that frequently becomes disabling.Osteoarthritis has been linked to maladaptive plasticity in the brain, which can contribute to chronic pain. Therapies including neuromodulation and peripheral electrical stimulation are used to counteract the maladaptive plasticity of the brain. OBJECTIVE: To determine the efficacy of the addition of tDCS and TENS to an education and exercise program in reducing pain. METHODS: Over a 2-week study period, 60 participants will complete an exercise and educational intervention. Eligible participants accepting to participate will be subsequently randomized into one of the three treatment groups: 1) Active Transcranial Direct Current Stimulation (tDCS) and active Transcutaneous Electrical Nerve Stimulation (TENS); 2) Active tDCS and sham TENS; 3) Sham tDCS and sham TENS. RESULTS: The primary outcome will be subjective pain intensity. SECONDARY OUTCOMES: quality of life, physical function, central sensitization, and pain adjuvants (uncertainty, catastrophizing kinesiophobia, adverse events). CONCLUSION: This clinical trial will provide data on the effect that the addition of tDCS and/or TENS to an education and exercise program may have to counteract maladaptive plastic changes and improve the benefits of exercises, and whether the combination of both neuromodulator techniques may have a higher magnitude of effect.

Knowledge and Attitudes towards Patient Safety among Students in Physical Therapy in Spain: A Longitudinal Study.

(1) Background: Patient safety is a discipline of health care management aiming to prevent and reduce errors and harm to patients. The assessment of knowledge and attitudes on patient safety among students in physical therapy is still scarce; no studies have yet explored the changes that internship periods may produce. Objectives: 1. to determine the attitudes and knowledge of students in physical therapy with respect to patient safety in a Spanish University; and 2. to explore changes following a practical internship period. (2) Methods: Longitudinal study. Data from the Attitudes to Patient Safety Questionnaire III (APSQ-III) before and after the internship period were obtained from an initial sample of 125 students and average positive response rates were compared. (3) Results: "Team functioning", "Importance of patient safety in the curriculum", and "Error inevitability" displayed the highest scores, in accordance with the current literature. After the internship period, the dimensions "Patient safety training received" (p = 0.001), "Error reporting confidence" (p = 0.044), and "Professional incompetence as an error cause" (p = 0.027) showed significant changes. (4) Conclusions: The current study, highlighting areas of strengths and weaknesses in the knowledge and attitudes of students in physical therapy towards patient safety, may be a foundation to adopt tailored programs to enhance students' competencies in patient safety.
