RESUMEN
BACKGROUND: The minimal important difference is a valuable metric in ascertaining the clinical relevance of a treatment, offering valuable guidance in patient management. There is a lack of available evidence concerning this metric in the context of outcomes related to female urinary incontinence, which might negatively impact clinical decision-making. OBJECTIVES: To summarize the minimal important difference of patient-reported outcome measures associated with urinary incontinence, calculated according to both distribution- and anchor-based methods. METHODS: This is a systematic review conducted according to the PRISMA guidelines. The search strategy including the main terms for urinary incontinence and minimal important difference were used in five different databases (Medline, Embase, CINAHL, Web of Science, and Scopus) in 09 June 2021 and were updated in January 09, 2024 with no limits for date, language or publication status. Studies that provided minimal important difference (distribution- or anchor-based methods) for patient-reported outcome measures related to female urinary incontinence outcomes were included. The study selection and data extraction were performed independently by two different researchers. Only studies that reported the minimal important difference according to anchor-based methods were assessed by credibility and certainty of the evidence. When possible, absolute minimal important differences were calculated for each study separately according to the mean change of the group of participants that slightly improved. RESULTS: Twelve studies were included. Thirteen questionnaires with their respective minimal important differences reported according to distribution (effect size, standard error of measurement, standardized response mean) and anchor-based methods were found. Most of the measures for anchor methods did not consider the smallest difference identified by the participants to calculate the minimal important difference. All reports related to anchor-based methods presented low credibility and very low certainty of the evidence. We pooled 20 different estimates of minimal important differences using data from primary studies, considering different anchors and questionnaires. CONCLUSIONS: There is a high variability around the minimal important difference related to patient-reported outcome measures for urinary incontinence outcomes according to the method of analysis, questionnaires, and anchors used, however, the credibility and certainty of the evidence to support these is still limited.

OBJECTIVE: This systematic review aims to summarize and synthesize the evidence that investigates the secondary effects of the application of botulinum toxin (BT) into the masticatory muscles and its effects on bone density. MATERIALS AND METHODS: Database searches were conducted until March 19th, 2024. The quality of the studies was assessed by the Cochrane tool risk of bias for the randomized controlled trials and the ROBINS-I tool for non-randomized studies. The Cochrane Grading of Recommendations Assessment Development and Evaluation (GRADE) was used to evaluate the confidence in the overall evidence. RESULTS: Five studies looking at the effects of botulinum toxin on bone density and resorption when applied to masticatory muscles were found. No significant changes were observed in most of the studies when looking at the effects of botulinum toxin on mandibular condyle volume, density, mandibular angle thickness, and coronoid process volume. The only finding that was statistically and clinically relevant was the difference between patients who received a double application of BT when compared with patients who received a single application (SMD: -0.99 [95%CI: -1.94,-0.05]) on the volume of the mandibular angle. CONCLUSIONS: There is no clear pattern on whether the application of botulinum toxin is associated with bone resorption or not. Although some studies show statistical significance of the findings, the magnitude of the changes in bone density and their clinical significance are not completely clear. CLINICAL RELEVANCE: To understand the effectiveness of the use of botulinum toxin into the masticatory muscles and its possible secondary adverse effects on the density of the mandible.

INTRODUCTION: Patients with chronic headaches and chronic oro-facial pain commonly present psychosocial issues that can affect social interactions. A possible reason could be that patients with these disorders might present impairments in facial recognition, laterality judgement and also alexithymia. However, a systematic review summarizing the effects of facial emotion recognition, laterality judgement and alexithymia in individuals with headaches and oro-facial pain is still not available. AIM: The main objective of this systematic review (SR) and meta-analysis (MA) was to compile and synthesize the evidence on the occurrence of alexithymia, deficits in laterality or left-right (LR) recognition and/or facial emotion recognition (FER) in patients with chronic headache and facial pain. METHODS: Electronic searches were conducted in five databases (up to September 2023) and a manual search to identify relevant studies. The outcomes of interest were alexithymia scores, speed and accuracy in LR and/or FER, or any other quantitative data assessing body image distortions. The screening process, data extraction, risk of bias and data analysis were performed by two independent assessors following standards for systematic reviews. RESULTS: From 1395 manuscripts found, only 34 studies met the criteria. The overall quality/certainty of the evidence was very low. Although the results should be interpreted carefully, individuals with chronic headaches showed significantly higher levels of alexithymia when compared to healthy individuals. No conclusive results were found for the other variables of interest. CONCLUSION: Although the overall evidence from this review is very low, people with chronic primary headaches and oro-facial pain could be regularly screened for alexithymia to guarantee appropriate management.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, about 81% of the world's population moved their workplace to a home office. OBJECTIVES: The main objective of this cross-sectional pilot study was to determine the impact of working and/or learning from home during the COVID-19 pandemic on the head, the neck and orofacial health in university students, faculty and staff. MATERIAL AND METHODS: Participants from 4 universities were recruited for an online survey. The survey included 33 questions related to demographics, health issues before and during the lockdown, work/study from home, and the awareness of the health effects of the lockdown. Descriptive statistics and single logistic regression analysis were employed. RESULTS: A total of 96 subjects aged 26 ±10.5 years participated in the study. Of these, 60% did not consider their home workstation to be adequate. The development of new symptoms or the worsening of the pre-existing symptoms was observed in 67%, 24%, 59%, and 37% of the participants with regard to neck pain, temporomandibular joint (TMJ)-related issues, headaches, and parafunctional oral habits, respectively. In addition, 87% of the respondents reported that their oral habits were aggravated by neck pain and a bad posture. As compared to the faculty and the staff, the students were more likely to experience headaches or the exacerbation of the pre-existing headaches during the pandemic. In the survey, 91% of the participants reported an increased awareness of the impact of the lockdown on their head and neck, and orofacial health. CONCLUSIONS: The present study helps understand the self-perceived effects of working and/or learning from home during the COVID-19 pandemic, and may facilitate implementing the appropriate models of treatment of the craniocervical-mandibular region during a pandemic.

External validity is an important parameter that needs to be considered for decision making in health research, but no widely accepted measurement tool for the assessment of external validity of randomized controlled trials (RCTs) exists. One of the most limiting factors for creating such a tool is probably the substantial heterogeneity and lack of consensus in this field. The objective of this study was to reach consensus on a definition of external validity and on criteria to assess the external validity of RCTs included in systematic reviews. A three-round online Delphi study was conducted. The development of the Delphi survey was based on findings from a previous systematic review. Potential panelists were identified through a comprehensive web search. Consensus was reached when at least 67% of the panelists agreed to a proposal. Eighty-four panelists from different countries and various disciplines participated in at least one round of this study. Consensus was reached on the definition of external validity ("External validity is the extent to which results of trials provide an acceptable basis for generalization to other circumstances such as variations in populations, settings, interventions, outcomes, or other relevant contextual factors"), and on 14 criteria to assess the external validity of RCTs in systematic reviews. The results of this Delphi study provide a consensus-based reference standard for future tool development. Future research should focus on adapting, pilot testing, and validating these criteria to develop measurement tools for the assessment of external validity.

OBJECTIVES: We systematically reviewed the reliability and measurement error of exercise-induced hypoalgesia (EIH) in pain-free adults and in adults with musculoskeletal (MSK) pain. METHODS: We searched EMBASE, PUBMED, SCOPUS, CINAHL, and PSYCINFO from inception to November 2021 (updated in February 2024). In addition, manual searches of the grey literature were conducted in March 2022, September 2023, and February 2024. The inclusion criteria were as follows: adults - pain-free and with MSK pain - a single bout of exercise (any type) combined with experimental pre-post pain tests, and assessment of the reliability and/or measurement error of EIH. Two independent reviewers selected the studies, assessed their Risk of Bias (RoB) with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) RoB tool, and graded the individual results (COSMIN modified Grading of Recommendations Assessment, Development, and Evaluation). RESULTS: We included five studies involving pain-free individuals (n = 168), which were deemed to have an overall "doubtful" RoB. No study including adults with MSK pain was found. The following ranges of parameters of reliability and measurement error of EIH were reported: intraclass correlation coefficients: 0-0.61; kappa: 0.01-0.46; standard error of measurement: 30.1-105 kPa and 10.4-21%; smallest detectable changes: 83.54-291.1 kPa and 28.83-58.21%. CONCLUSIONS: We concluded, with a very low level of certainty, that the reliability and measurement error of EIH is, in pain-free adults, respectively, "insufficient" and "indeterminate." Future studies should focus on people with MSK pain and could consider using tailored exercises, other test modalities than pressure pain threshold, rater/assessor blinding, and strict control of the sources of variations (e.g., participants' expectations).

OBJECTIVE: The objectives of this scoping review were to provide an overview of existing guidelines for the development and validation of patient-reported outcome measures (PROMs), review them for comprehensiveness and clarity and provide recommendations for their use based on the goals of the instrument developers. DESIGN: Scoping review. METHODS: A literature search was performed in PubMed, Scopus, PsycInfo and Google Scholar up to 2 June 2023 to identify guidelines for the development and validation of PROMs. Screening of records and reports as well as data extraction were performed by two reviewers. To assess the comprehensiveness of the included guidelines, a mapping synthesis was performed and steps to develop and validate a measurement instrument outlined in the included guidelines were mapped to an a priori framework including 20 steps, which was based on the guideline by de Vet et al. RESULTS: A total of 40 guidelines were included. Statistical advice (at least partially) was provided in 98% of the guidelines (39/40) and 88% (35/40) of the guidelines included examples for steps required to develop and validate PROMs. However, 78% (31/40) of the guidelines were not comprehensive and two essential steps in PROM development ('consideration and elaboration of the measurement model' and 'responsiveness') were not included in 80% and 72% of the guidelines, respectively. Three guidelines included all 20 steps and six included almost all steps (≥90% of steps) for developing and validating a PROM. DISCUSSION: Most guidelines on PROM development and validation do not appear to be comprehensive, and some crucial steps are missing in most guidelines. Nevertheless, for some purposes of PROMs, many guidelines provide helpful advice and support. CONCLUSION: At least 15 guidelines may be recommended, including three comprehensive guidelines that can be recommended for the development and validation of PROMs for most purposes (eg, to discriminate between subjects with a particular condition and subjects without that condition, to evaluate the effects of treatments (between a pre and post time-points) or to evaluate a status quo).
RESUMEN
PURPOSE: To determine the effectiveness of different types of acupuncture in reducing pain, improving maximum mouth opening and jaw functions in adults with orofacial pain. METHODS: Six databases were searched until 15 June 2023. The Cochrane risk of bias tool and GRADE were employed to evaluate bias and overall evidence certainty. RESULTS: Among 52 studies, 86.5% (n = 45) exhibited high risk of bias. Common acupoints, including Hegu LI 4, Jiache ST 6, and Xiaguan ST 7, were used primarily for patients with temporomandibular disorder [TMDs]. Meta-analyses indicated that acupuncture significantly reduced pain intensity in individuals with myogenous TMD (MD = 26.02 mm, I2=89%, p = 0.05), reduced tenderness in the medial pterygoid muscle (standardised mean differences [SMD] = 1.72, I2 = 0%, p < 0.00001) and jaw dysfunction (SMD = 1.62, I2 = 88%, p = 0.010) in mixed TMD when compared to sham/no treatment. However, the overall certainty of the evidence was very low for all outcomes as evaluated by GRADE. CONCLUSION: The overall results in this review should be interpreted with caution as there was a high risk of bias across the majority of randomized controlled trial (RCTs), and the overall certainty of the evidence was very low. Therefore, future studies with high-quality RCTs are warranted evaluating the use of acupuncture in patients with orofacial pain.
Acupuncture could potentially reduce subjective pain intensity and sensitivity of masticatory muscles, improve mouth opening, and reduce dysfunction in orofacial pain, specifically in patients with temporomandibular disorder (TMD).Acupuncture points such as LI4, ST6, ST7, GB20, SI19, ST36 were the most commonly used acupuncture points to treat patients with orofacial pain, especially TMDs.Clinicians can use the information in this review with caution to develop an effective and appropriate treatment regimen for the acupuncture treatment of patients with TMDs.
RESUMEN
ABSTRACT: This review presents a comprehensive summary and critical evaluation of intention-to-treat analysis, with a particular focus on its application to randomized controlled trials within the field of rehabilitation. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted a methodological review that encompassed electronic and manual search strategies to identify relevant studies. Our selection process involved two independent reviewers who initially screened titles and abstracts and subsequently performed full-text screening based on established eligibility criteria. In addition, we included studies from manual searches that were already cataloged within the first author's personal database. The findings are synthesized through a narrative approach, covering fundamental aspects of intention to treat, including its definition, common misconceptions, advantages, disadvantages, and key recommendations. Notably, the health literature offers a variety of definitions for intention to treat, which can lead to misinterpretations and inappropriate application when analyzing randomized controlled trial results, potentially resulting in misleading findings with significant implications for healthcare decision making. Authors should clearly report the specific intention-to-treat definition used in their analysis, provide details on participant dropouts, and explain upon their approach to managing missing data. Adherence to reporting guidelines, such as the Consolidated Standards of Reporting Trials for randomized controlled trials, is essential to standardize intention-to-treat information, ensuring the delivery of accurate and informative results for healthcare decision making.

BACKGROUND: There is clear evidence demonstrating the benefits of physical activity (PA) on pain and overall health, however, PA is challenging for many individuals living with chronic pain. Even non-exercise specialists can (cost) effectively promote PA, but many health professionals report a number of barriers in providing guidance on PA, suggesting that it is not consistently promoted. This expert position paper summarizes the evidence and provides five recommendations for health professionals to assess, advise and support individuals living with any chronic pain condition with a long life expectancy in adopting and sustaining physically active lifestyles. METHODS: This position paper was prepared by the 'On The Move' Task Force of the European Pain Federation EFIC. Final recommendations were endorsed by the European Pain Forum, Pain Alliance Europe and the Executive Board of EFIC. RESULTS: We recommend that all health professionals (1) Take a history of the persons' PA levels, and put PA on the agenda, (2) Advise that PA is important and safe for individuals living with chronic pain, (3) Deliver a brief PA intervention and support individuals living with chronic pain in becoming physically active, (4) Discuss acceptable levels of PA-related soreness and pain and (5) Provide ongoing support in staying physically active. SIGNIFICANCE: Physical activity is safe and offers several advantages, including general health benefits, low risk of side effects, low cost and not requiring access to healthcare. Adoption of these recommendations can improve the quality of care and life of individuals living with chronic pain and reduce their overall health risks.

Objetivo: Determinar las alteraciones teleradiográficas craneocervicales en pacientes con desplazamiento anterior de disco con reducción. Método: Se realizó un estudio no experimental descriptivo. Se evaluaron 439 pacientes entre 5 y 73 años que consultaron al adontólogo en los consultorios de Talca-Chile, por causa dental. Se extrajo la muestra por conveniencia, quedando constituido un grupo de estudio (pacientes con desplazamiento anterior de disco con reducción (DADR) y un grupo control (sanos), con 25 pacientes cada uno. Se realizó una evaluación clínica a cada grupo y luego se les efectuó una teleradiografía de perfil, la cual fue analizada cefalométricamente a través del análisis propuesto por Mariano Rocabado para investigar las variables de rotación posterior de cráneo y espacios cráneocervicales. Para analizar la lordosis cervical se utilizó el índice de Ishihara. Los resultados se analizaron en forma descriptiva a través de porcentaje. Resultados: De acuerdo a la hipótesis planteada se observó que el 80 por ciento de los pacientes del grupo de estudio presentó un ángulo cráneo vertebral (ACV) alterado del cual el 60 por ciento correspondió a una rotación posterior de cráneo (RPC) y el 40 por ciento una rotación anterior de cráneo (RAC). En relación al índice de Ishihara (ICC), se encontró que el 16 por ciento del grupo control y el 28 por ciento del grupo en estudio presentó un ICC alterado. Conclusión: Existe una tendencia y no un patrón absoluto, entre una alteración del ACV y el DADR. No se encontró relación directa entre el ICC y el DADR
