Somatosensory Profiling of Patients With Cluster Headache: A Systematic Review and Meta-analysis.

The objectives were 1) to synthesize quantitative sensory testing results in cluster headache (CH) patients and to identify somatosensory differences from healthy subjects (HS), and 2) between symptomatic and asymptomatic sides in CH patients. Two independent reviewers conducted a literature search in MEDLINE, EMBASE, Web of Science, and CINAHL databases. Studies with observational designs were included. Methodological quality and risk of bias were assessed with the Newcastle Ottawa Scale. The selected studies underwent qualitative and quantitative analyses. The qualitative analysis showed inconsistent findings among multiple studies. Meta-analysis showed lower pressure pain thresholds (PPTs) on the symptomatic side of CH patients than HS in V2 (standardized mean difference [SMD] -1.01 [95% confidence interval (CI) -1.79, -.23], P = .01, I2 = 73%, n = 114), V3 (SMD -1 [95% CI -1.54, .45], P < .01, I2 = 82%, n = 354), and cervical region (SMD -1.25 [95% CI -2.07, -.44], P < .01, I2 = 84%, n = 194). Furthermore, lower PPTs than those detected in HS were found on the asymptomatic side in V3 (SMD -.77 [95% CI -1.27, -.27], P < .01, I2 = 79%, n = 354) and in the cervical region (SMD -1.13 [95% CI -1.97, -.3], P < .01, I2 = 85%, n = 194). However, no differences were found in V1 or the extratrigeminal points between these groups. No significant changes were found between symptomatic and asymptomatic sides in trigeminal and extratrigeminal regions. Mechanical hyperalgesia in the trigemino-cervical region of patients with CH could suggest the presence of central pain mechanisms. These results are of clinical relevance because their presence could be associated with a poorer prognosis, chronification, and treatment response. PERSPECTIVES: This study provides consistent findings on the somatosensory profile characterizing patients with CH. Clinicians should assess PPTs and other quantitative sensory testing variables in the trigeminal and extratrigeminal (cervical) regions.

Cognitive Reserve in Parkinson's Disease without Dementia: ß-Amyloid and Metabolic Assessment.

BACKGROUND: Cognitive reserve (CR) is the mismatch between preserved cognition and neuropathological damage. Amyloidopathy in Parkinson's disease (PD) could be associated with faster progression to dementia, but the putative protective effect of CR is unknown. OBJECTIVES: To evaluate the effect of CR on ß-amyloid burden and brain metabolism in non-demented PD subjects. METHODS: Participants with PD (n = 53) underwent a clinical evaluation, [18 F]-fluorodeoxyglucose and [18 F]-flutemetamol positron emission tomography magnetic resonances, and were classified according to CR. The metabolic pattern of 16 controls was compared to PD subjects. RESULTS: The PD subjects showed hypometabolism mainly in the bilateral posterior cortex. Superior-CR subjects (n = 22) exhibited better cognitive performance, increased amyloid burden, and higher metabolism in several right hemisphere areas compared to low-medium-CR subjects (n = 31). CONCLUSIONS: Higher CR in non-demented PD is associated with better cognitive performance, which might reduce vulnerability to the effect of ß-amyloid. Whether superior CR leads to protection against metabolic deterioration, and predominantly right hemisphere involvement, deserves further exploration.

Effects of Non-Invasive Neuromodulation of the Vagus Nerve for Management of Tinnitus: A Systematic Review with Meta-Analysis.

BACKGROUND: Tinnitus is the perception of sound in the absence of actual external stimuli. Other associated symptoms include frustration, annoyance, anxiety, depression, stress, cognitive dysfunction, insomnia, or emotional exhaustion. OBJECTIVE: In this study, we aimed to conduct a systematic review and meta-analysis on the effectiveness of the non-invasive neuromodulation of the vagus nerve in patients with tinnitus. METHODS: Six databases were searched from their date of inception to 15 June 2022 to identify clinical trials in which at least one group received any form of non-invasive neuromodulation of the vagus nerve for tinnitus management, with outcomes based on annoyance and related disability. Data on participants, interventions, blinding strategies, assessment outcomes, and results were extracted by two reviewers. RESULTS: The search identified 183 articles with five clinical trials eligible for inclusion in the review and four for the meta-analysis. The methodological quality scores ranged from 6 to 8 (mean: 7.3, SD: 0.8) points. The meta-analysis identified a significant positive effect on THI post-treatment for unilateral auricular stimulation (hg = 0.69, 95% CI 0.06, 1.32) or transcutaneous nerve stimulation (hg = 0.51, 95% CI 0.1, 0.9) compared with a comparative group. No effect on loudness intensity was observed. CONCLUSION: The results of the meta-analysis suggest that the application of the non-invasive neuromodulation of the vagus nerve has a positive effect post-treatment in terms of related disability in patients with tinnitus, although its clinical relevance is low. No firm conclusions about the effect of the non-invasive neuromodulation of the vagus nerve on tinnitus are available based on the current literature.

Morphological Changes of the Suboccipital Musculature in Women with Myofascial Temporomandibular Pain: A Case-Control Study.

Temporomandibular disorder (TMD) is an umbrella term including pain problems involving the cranio-cervical region. It has been suggested that patients with TMD also exhibit cervical spine disturbances. Evidence suggests the presence of morphological changes in the deep cervical muscles in individuals with headaches. The objective of this study was to compare the morphology of the suboccipital muscles between women with TMD and healthy controls. An observational, cross-sectional case-control study was conducted. An ultrasound examination of the suboccipital musculature (rectus capitis posterior minor, rectus capitis posterior major, oblique capitis superior, oblique capitis inferior) was conducted in 20 women with myofascial TMD and 20 matched controls. The cross-sectional area (CSA), perimeter, depth, width, and length of each muscle were calculated by a blinded assessor. The results revealed that women with myofascial TMD pain exhibited bilaterally reduced thickness, CSA, and perimeter in all the suboccipital muscles when compared with healthy women. The width and depth of the suboccipital musculature were similar between women with myofascial TMD and pain-free controls. This study found morphological changes in the suboccipital muscles in women with myofascial TMD pain. These changes can be related to muscle atrophy and are similar to those previously found in women with headaches. Future studies are required to investigate the clinical relevance of these findings by determining if the specific treatment of these muscles could help clinically patients with myofascial TMD.

Effects of Physiotherapy on Pain and Mouth Opening in Temporomandibular Disorders: An Umbrella and Mapping Systematic Review with Meta-Meta-Analysis.

The aim of this meta-meta-analysis was to assess the current evidence regarding the effect of physical therapy (PT) interventions on pain and functional variables in temporomandibular disorders (TMD). We conducted an umbrella systematic review (SR) and four meta-meta-analyses (MMA) and created an evidence map to determine the effectiveness of PT on pain intensity and maximum mouth opening in patients with TMD. The quality of the included SR was assessed with the AMSTAR 2, and the risk of bias with ROBIS. Of the 31 SR included in the umbrella SR, only 10 were included in the MMA. The MMA showed moderate effects for manual therapy and therapeutic exercise, and large effects for low-level laser therapy on improving pain intensity and maximum mouth opening in patients with TMD, with a limited to moderate quality of evidence. The overlapping analyses showed only a slight overlap for all the MMA according to the corrected covered area (range from 0.07 to 0.2), 23.1% to 41.6%. This umbrella SR showed that manual therapy and exercise interventions, as well as low-level laser therapy interventions, are effective in the reduction in pain intensity and improvement of maximum mouth opening in TMD. This article presents a synthesis of the available evidence related to the various physical therapy interventions used in patients presenting with temporomandibular disorders. These results could help clinicians to select the optimal intervention for their patients and to reject those that are less useful.

Respiratory dysfunction in patients with chronic neck pain: systematic review and meta-analysis.

PURPOSE: To determine the differences in respiratory muscle strength and pulmonary function between patients with chronic neck pain (CNP) and asymptomatic individuals. METHODS: Databases were MEDLINE, CINAHL, Scopus, Web of Science and EMBASE up to the end of September 2021. Studies with cross-sectional and longitudinal design were selected, with adult patients with CNP and asymptomatic individuals with reports respiratory function. RESULTS: 11 studies met the inclusion criteria and 10 were included in the meta-analysis showing a statistically significant reduction in inspiratory/expiratory muscle strength (MIP/MEP) in the patients with CNP compared with the asymptomatic individuals (mean difference (MD) for MIP, -11.67 [-14.57 to -8.77]; MD for MEP, -11.80 [-14.99 to -8.60]) and pulmonary function: vital capacity (standardized mean difference (SMD), -0.31 [-0.56 to -0.06]); maximum voluntary ventilation (SMD, -0.36 [-0.59 to -0.14]); forced vital capacity (SMD, -0.53 [-0.99 to -0.06]); peak expiratory flow (SMD, -0.58 [-1.03 to -0.12]); and forced expiratory volume in the first second (SMD, -0.28 [-0.51 to -0.05]). CONCLUSIONS: Patients with CNP have reduced respiratory muscle strength and pulmonary function compared with asymptomatic individuals, and this difference could be clinically meaningful. However, more studies of high methodological quality and longitudinal studies are needed to strengthen the results of this meta-analysis. IMPLICATIONS FOR REHABILITATIONRespiratory dysfunction has been observed in patients with chronic neck pain.Patients with chronic neck pain present a decrease in respiratory muscle strength and pulmonary function compared with asymptomatic individuals.Respiratory pattern disorders should be considered in the clinical context of chronic neck pain.Interventions focused on respiratory muscle training could be helpful for this population.

Respiratory muscle training improves exercise tolerance and respiratory muscle function/structure post-stroke at short term: A systematic review and meta-analysis.

BACKGROUND: Previous reviews relating to the effects of respiratory muscle training (RMT) after stroke tend to focus on only one type of training (inspiratory or expiratory muscles) and most based the results on poor-quality studies (PEDro score ≤4). OBJECTIVES: With this systematic review and meta-analysis, we aimed to determine the effects of RMT (inspiratory or expiratory muscle training, or mixed) on exercise tolerance, respiratory muscle function and pulmonary function and also the effects depending on the type of training performed at short- and medium-term in post-stroke. METHODS: Databases searched were MEDLINE, PEDro, CINAHL, EMBASE and Web of Science up to the end of April 2020. The quality and risk of bias for each included study was examined by the PEDro scale (including only high-quality studies) and Cochrane Risk of Bias tool. RESULTS: Nine studies (463 patients) were included. The meta-analysis showed a significant increase in exercise tolerance [4 studies; n = 111; standardized mean difference [SMD] = 0.65 (95% confidence interval 0.27-1.04)]; inspiratory muscle strength [9 studies; n = 344; SMD = 0.65 (0.17-1.13)]; inspiratory muscle endurance [3 studies; n = 81; SMD = 1.19 (0.71-1.66)]; diaphragm thickness [3 studies; n = 79; SMD = 0.9 (0.43-1.37)]; and peak expiratory flow [3 studies; n = 84; SMD = 0.55 (0.03-1.08)] in the short-term. There were no benefits on expiratory muscle strength and pulmonary function variables (forced expiratory volume in 1 s) in the short-term. CONCLUSIONS: The meta-analysis provided moderate-quality evidence that RMT improves exercise tolerance, diaphragm thickness and pulmonary function (i.e., peak expiratory flow) and low-quality evidence for the effects on inspiratory muscle strength and endurance in stroke survivors in the short-term. None of these effects are retained in the medium-term. Combined inspiratory and expiratory muscle training seems to promote greater respiratory changes than inspiratory muscle training alone.

Motor effects of movement representation techniques and cross-education: a systematic review and meta-analysis.

INTRODUCTION: The objective was to assess the impact of movement representation techniques (MRT) through motor imagery (MI), action observation (AO) and visual mirror feedback (VMF) and cross-education training (CE) on strength, range of motion (ROM), speed, functional state and balance during experimental immobilization processes in healthy individuals, in patients with injuries that did not require surgery and in those with surgical processes that did or did not require immobilization. EVIDENCE ACQUISITION: MEDLINE, EMBASE, CINAHL and Google Scholar were searched. Thirteen meta-analyses were conducted. EVIDENCE SYNTHESIS: Regarding the immobilized participants, in the healthy individuals, MI showed significant results regarding maintenance of strength and ROM, with low-quality evidence. Regarding the process with no immobilization, VMF and MI techniques showed significant changes in maintaining ROM in patients with injury without surgery, with very low-quality evidence. Results had shown that MI demonstrated significantly higher maintenance of strength and speed in patients undergoing surgery, with low-quality evidence. No significant results were found in ROM. Low-quality evidence showed better results in AO plus usual care compared with usual treatment in isolation with respect to maintenance of functional state and balance. CE training demonstrated maintenance of strength in patients undergoing surgery, with moderate evidence; however, not in healthy experimentally immobilized individuals. VMF did not show significant results in maintaining ROM after surgery without immobilization, nor did MI in maintaining strength after surgery and immobilization. CONCLUSIONS: MRT and CE training have been shown to have a significant impact on the improvement of various motor variables and on physical maintenance in general.

Pain relief by movement representation strategies: An umbrella and mapping review with meta-meta-analysis of motor imagery, action observation and mirror therapy.

OBJECTIVE: To develop a mapping and umbrella review with a meta-meta-analysis (MMA) to critically evaluate the current evidence of motor imagery (MI), action observation and mirror therapy (MT) on pain intensity. METHODS: The study involved a systematic search of PubMed, PEDro, Scielo, EBSCO and Google Scholar. RESULTS: Ten systematic reviews were included in the qualitative synthesis, 70% of which showed high methodological quality. Three reviews found a significant reduction in chronic musculoskeletal pain as the result of applying movement representation methods (MRM) plus usual-care (UC), with a large clinical effect (standardized mean difference [SMD] of -1.47; 95% CI -2.05 to -0.88; heterogeneity Q = 1.66; p = 0.44; I2  = 0%). However, two reviews showed no statistically significant reduction in acute and postsurgical pain as a result of applying MI plus UC. Four reviews showed no significant reduction in phantom limb pain (PLP) as a result of applying MT plus UC interventions. In four reviews, the MMA showed a significant reduction in complex regional pain syndrome (CRPS) as a result of applying MT plus UC, with a large clinical effect (SMD -1.27; 95% CI -1.87 to -0.67; heterogeneity Q = 3.95; p = 0.27; I2  = 24%). In two reviews, the MMA showed no significant differences in poststroke pain as a result of applying MT plus UC. CONCLUSION: Results show that MRM could be effective for chronic musculoskeletal pain, with low to moderate-quality evidence. The results also show a reduction in pain intensity through MT interventions in patients with CRPS, although these results were not found in patients with PLP or poststroke pain. SIGNIFICANCE: This umbrella review analysed systematic reviews evaluating movement representation techniques, with the aim of synthesizing the available evidence regarding motor imagery, action observation and mirror therapy on pain. The results provide relevant information about the potential clinical use of movement representation techniques in different types of patients with painful conditions.

Alexithymia and facial emotion recognition in patients with craniofacial pain and association of alexithymia with anxiety and depression: a systematic review with meta-analysis.

BACKGROUND: We aimed to determine the presence of alexithymia in patients with craniofacial pain (CFP) compared with asymptomatic individuals. Our secondary aims were to assess the relationship of alexithymia with anxiety and depression levels, as well as to assess the presence of facial emotion recognition deficit. METHODS: Medline, Scielo and Google Scholar were searched, with the last search performed in 8 September 2021. Standardized mean differences (SMDs) and 95% CIs were calculated for relevant outcomes and were pooled in a meta-analysis using the random effects model. In addition, meta-analyses of correlations and a meta-regression of alexithymia with depression and anxiety were performed. RESULTS: Regarding alexithymia, assessed through the Toronto Alexithymia Scale (TAS), the results showed significant differences, with higher values in patients compared with asymptomatic individuals, with a large clinical effect (SMD 0.46; 95% CI [0.22-0.71]; heterogeneity-Q 66.86; p < 0.001; inconsistency (I2) = 81%). We found statistically significant correlations with a small clinical effect of alexithymia with anxiety and depression. The meta-regression showed no significant association between the TAS and anxiety or depression. With respect to facial emotion recognition, the results showed statistically significant differences, with greater recognition difficulty in patients compared with asymptomatic individuals, with a large clinical effect (SMD -1.17; 95% CI [-2.01 to -0.33]; heterogeneity-Q 2.97; p = 0.080; I2 = 66%). CONCLUSIONS: Patients with CFP showed alexithymia with moderate evidence. There was also moderate evidence indicating that these patients had significant deficits in facial emotion recognition compared with asymptomatic individuals. Furthermore, alexithymia showed statistically significant correlations with anxiety and depression levels.

Effectiveness of Telerehabilitation in Physical Therapist Practice: An Umbrella and Mapping Review With Meta-Meta-Analysis.

OBJECTIVE: Telerehabilitation is an option that should be adapted as soon as possible to face the crisis caused by coronavirus disease 2019. An umbrella and mapping review with meta-meta-analysis (MMA) of the available scientific evidence was performed to determine whether telerehabilitation could be an effective alternative to conventional rehabilitation in physical therapist practice. METHODS: A systematic review of reviews and a synthesis of the findings of all systematic evidence published to date with a visual map and a meta-meta-analysis (MMA) were performed. A systematic search was realized in Cochrane Database of Systematic Reviews, MEDLINE (PubMed), and Google Scholar. Two independent reviewers performed a data analysis and assessed the quality of the included reviews, assessing the risk of bias using ROBIS. RESULTS: Twenty-nine articles that met the inclusion criteria were selected and divided according to the type of patient targeted for rehabilitation (patients with cardiorespiratory, musculoskeletal, and neurological conditions). The MMA regarding physical function between telerehabilitation and usual care rehabilitation did not reveal a statistically significant difference for patients with cardiorespiratory and musculoskeletal conditions. For patients with neurological conditions, the MMA revealed a statistically significant but negligible effect size in 6 reviews in favor of telerehabilitation (standardized mean difference = 0.18; 95% CI = 0.03-0.34). CONCLUSION: The results of the present review showed that telerehabilitation offers positive clinical results, even comparable to conventional face-to-face rehabilitation approaches. IMPACT: The advantages of lower cost and less interference by the rehabilitation processes in patients' daily life could justify implementing telerehabilitation in clinical settings in the coronavirus disease 2019 era.

Waist circumference as a prognostic index of childhood abdominal obesity: findings in the Spanish population / Circunferencia de la cintura como índice pronóstico de obesidad abdominal infantil: hallazgos en la población española

INTRODUCTION: early detection of childhood obesity plays a crucial role in the prevention of diseases during adulthood. At present, the most commonly used screening tool for detecting overweight/obesity in children is the percentile for age of body mass index, although this rate is unable to provide information about fat distribution. An emerging marker of abdominal fat distribution is waist circumference (WC). OBJECTIVE: the aim of this study was to evaluate the differences between the different diagnostic criteria available to define overweight and obesity in order to establish the optimal WC cut-off values for the Spanish children population. METHODS: a cross-sectional study was carried out in 8,241 schoolchildren aged 3 to 12 years from Villanueva de la Cañada (Madrid, Spain). WC (cm), weight (kg) and height (cm) were measured according to the recommendations of the Society for the Advancement of Kineanthropometry (ISAK). The values obtained for the diagnostic criteria (Spanish Orbegozo Foundation (OF), the International Obesity Task Force (IOTF), and the World Health Organization (WHO) were compared using McNemar's test for paired proportions. The kappa coefficient (κ) was used to assess the degree of agreement of the three classifications. We analyzed the validity of body mass index (BMI) and WC using the receiver operating characteristic (ROC) curve analysis. The Youden index was used to determine cut-off values for WC that identify childhood obesity RESULTS: overweight and obesity prevalences were calculated according to the OF, IOTF, and WHO criteria. There was a "substantial" agreement for the overweight and obesity categories between the Spanish criteria and IOTF (κ = 0.636), while agreement was "slight" between the Spanish criteria and those of WHO (κ = 0.198). The estimated cut-off WC criteria ranged from 54.5 to 88.0, varying according to sex and age. CONCLUSION: the proposed WC cut-off values, stated for the first time in a young Spanish population, are a simple and valid alternative as diagnostic criteria of abdominal obesity

INTRODUCCIÓN: la detección temprana de la obesidad durante la infancia es de vital importancia para la prevención de patologías durante la edad adulta. En la actualidad, la evaluación de la obesidad infantil se realiza principalmente utilizando el índice de masa corporal por edad percentilado, aunque este no aporta información sobre la distribución del tejido adiposo. Un marcador emergente de distribución de la grasa abdominal es la circunferencia de la cintura (CC). OBJETIVO: el objetivo de este trabajo fue evaluar las diferencias entre diferentes criterios diagnósticos para definir el sobrepeso y la obesidad con el fin de establecer el punto de corte óptimo de la CC en los niños españoles. MÉTODO: se llevó a cabo un estudio observacional transversal de 8241 niños/as (3-12 años) en Villanueva de la Cañada (Madrid, España). Se determinaron el peso, la talla y el perímetro de la cintura atendiendo a los criterios de la Sociedad Internacional para el Avance de la Cineantropometría (ISAK). Los valores obtenidos para los criterios diagnósticos (Fundación Orbegozo (OF), el Grupo Internacional de Obesidad (IOTF) y la Organización Mundial de la Salud (OMS)) se compararon utilizando la prueba de McNemar para proporciones emparejadas. El coeficiente kappa (κ) se utilizó para evaluar el grado de acuerdo de las tres clasificaciones. Analizamos la validez del índice de masa corporal (IMC) y el perímetro de la cintura (CC) utilizando el análisis de la curva característica operativa del receptor (ROC). El índice de Youden se utilizó para determinar los valores de corte de la CC que identifican la obesidad infantil. RESULTADOS: se calcularon las prevalencias del sobrepeso y la obesidad de acuerdo con criterios internacionales (IOTF, OMS) y nacionales (FO). Se observó un acuerdo "substancial" para el sobrepeso y la obesidad entre el criterio diagnóstico español y el IOTF (κ = 0,636), mientras que el acuerdo fue "ligero" entre el criterio español y el de la OMS (κ = 0,198). Los puntos de corte de la CC estimados variaron de 54,5 a 88,0 cm, modificándose en función de la edad y el sexo. CONCLUSIONES: los puntos de corte de la CC propuestos, establecidos por primera vez para niños españoles, son una alternativa simple y válida como criterio diagnóstico de obesidad abdominal

Effectiveness of motor imagery and action observation on functional variables: An umbrella and mapping review with meta-meta-analysis.

To assess the current evidence on motor imagery (MI) and action observation (AO) and their influence on functional variables. We conducted 3 meta-meta-analyses (MMA) to determine the effectiveness of MI and AO on arm functionality, performance on activities of daily living and gait mobility in stroke patients. For arm functionality, MMA revealed a statistically significant large effect size (standardised mean difference [SMD] = 1.05; 95 % CI 0.50-1.60; p<.001) but with evidence of heterogeneity (Q=55.67, p<.001, I2=93 %). For arm performance in activities of daily living, MMA revealed a significantly large effect size (SMD=1.76; 95 % CI 1.10-2.43; p<.001) but also with evidence of heterogeneity (Q=1.62, p=.44, I2=90 %). MMA showed no significant effects favouring intervention regarding gait mobility. The results of the systematic reviews showed that movement representation techniques combined with the usual treatment have a positive impact on improving function, with a very low to moderate quality of evidence for all variables except for range of motion in acute disorders and strength. MI and AO showed positive results for improving functional variables.

Craniocervical and Cervical Spine Features of Patients with Temporomandibular Disorders: A Systematic Review and Meta-Analysis of Observational Studies.

To assess neck disability with respect to jaw disability, craniocervical position, cervical alignment, and sensorimotor impairments in patients with temporomandibular disorders (TMD), a systematic review and meta-analysis of observational studies trials were conducted. The meta-analysis showed statistically significant differences in the association between neck disability and jaw disability (standardized mean difference (SMD), 0.72 (0.56-0.82)). However, results showed no significant differences for cervical alignment (SMD, 0.02 (-0.31-0.36)) or for the craniocervical position (SMD, -0.09 (-0.27-0.09)). There was moderate evidence for lower pressure pain thresholds (PPT) and for limited cervical range of motion (ROM). There was limited evidence for equal values for maximal strength between the patients with TMD and controls. There was also limited evidence for reduced cervical endurance and conflicting evidence for abnormal electromyographic (EMG) activity and motor control in TMD patients. Results showed a clinically relevant association between cervical and mandibular disability in patients with TMD. Regarding sensory-motor alterations, the most conclusive findings were observed in the reduction of PPT and cervical ROM, with moderate evidence of their presence in the patients with TMD. Lastly, the evidence on impaired motor control and cervical EMG activity in patients with TMD was conflicting.

Development and Preliminary Evaluation of the Effects of an mHealth Web-Based Platform (HappyAir) on Adherence to a Maintenance Program After Pulmonary Rehabilitation in Patients With Chronic Obstructive Pulmonary Disease: Randomized Controlled Trial.

BACKGROUND: Pulmonary rehabilitation is one of the main interventions to reduce the use of health resources, and it promotes a reduction in chronic obstructive pulmonary disease (COPD) costs. mHealth systems in COPD aim to improve adherence to maintenance programs after pulmonary rehabilitation by promoting the change in attitude and behavior necessary for patient involvement in the management of the disease. OBJECTIVE: This study aimed to assess the effects of an integrated care plan based on an mHealth web-based platform (HappyAir) on adherence to a 1-year maintenance program applied after pulmonary rehabilitation in COPD patients. METHODS: COPD patients from three hospitals were randomized to a control group or an intervention group (HappyAir group). Patients from both groups received an 8-week program of pulmonary rehabilitation and educational sessions about their illness. After completion of the process, only the HappyAir group completed an integrated care plan for 10 months, supervised by an mHealth system and therapeutic educator. The control group only underwent the scheduled check-ups. Adherence to the program was rated using a respiratory physiotherapy adherence self-report (CAP FISIO) questionnaire. Other variables analyzed were adherence to physical activity (Morisky-Green Test), quality of life (Chronic Obstructive Pulmonary Disease Assessment Test, St. George's Respiratory Questionnaire, and EuroQOL-5D), exercise capacity (6-Minute Walk Test), and lung function. RESULTS: In total, 44 patients were recruited and randomized in the control group (n=24) and HappyAir group (n=20). Eight patients dropped out for various reasons. The CAP FISIO questionnaire results showed an improvement in adherence during follow-up period for the HappyAir group, which was statistically different compared with the control group at 12 months (56.1 [SD 4.0] vs 44.0 [SD 13.6]; P=.004) after pulmonary rehabilitation. CONCLUSIONS: mHealth systems designed for COPD patients improve adherence to maintenance programs as long as they are accompanied by disease awareness and patient involvement in management.

Medication-related osteonecrosis of the jaws (MRONJ) in cancer patients treated with denosumab VS. zoledronic acid: A systematic review and meta-analysis

BACKGROUND: The aim of the present study was to analyse the incidence, risk ratio (RR) and prognoses of two types of medication-related osteonecrosis of the jaws (MRONJ): denosumab-related osteonecrosis of the jaws (DRONJ) and Bisphosphonate-Related Osteonecrosis of the Jaws (BRONJ) in cancer patients under treatment with deno-sumab or zoledronic acid (ZA). MATERIAL AND METHODS: An electronic and manual search was conducted for randomized controlled trials (RCTs) until May 2019. Assessment of the identified studies, risk of bias and data extraction were performed independently by two reviewers. The incidence of DRONJ and BRONJ and the RR to develop MRONJ were calculated at 1 year, 2 years and 3 years of exposure. It was also calculated the odds ratio (OR) of their respective prognoses. They were calculated normalizing the values of the individual studies to 1 year, 2 years or 3 years when necessary through robust regression models using a statistical program. RESULTS: From 1.277 references identified, 8 RCTs were included, which comprised a total of 13.857 patients with a variety of neoplasms. The incidence of DRONJ in cancer patients under treatment with denosumab ranged from 0.5 to 2.1% after 1 year, 1.1 to 3.0% after 2 years, and 1.3 to 3.2% after 3 years of exposure. The incidence of BRONJ in cancer patients under treatment with ZA ranged from 0.4 to 1.6% after 1 year of exposure, 0.8 to 2.1% after 2 years, and 1.0 to 2.3% after 3 years of exposure. Statistically significant differences were found between de-nosumab and ZA in the risk of developing MRONJ after 1, 2 and 3 years of exposure. Nevertheless, there were no significant differences in terms of patient prognosis. CONCLUSIONS: Denosumab is associated with a significantly higher risk of developing MRONJ compared to ZA. Nevertheless, no differences were found in its prognoses

Effect of Manual Therapy and Therapeutic Exercise Applied to the Cervical Region on Pain and Pressure Pain Sensitivity in Patients with Temporomandibular Disorders: A Systematic Review and Meta-analysis.

OBJECTIVE: To assess the effectiveness of cervical manual therapy (MT) on patients with temporomandibular disorders (TMDs) and to compare cervico-craniomandibular MT vs cervical MT. DESIGN: Systematic review and meta-analysis (MA). METHODS: A search in PubMed, EMBASE, PEDro, and Google Scholar was conducted with an end date of February 2019. Two independent reviewers performed the data analysis, assessing the relevance of the randomized clinical trials regarding the studies' objectives. The qualitative analysis was based on classifying the results into levels of evidence according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE). RESULTS: Regarding cervical MT, MA included three studies and showed statistically significant differences in pain intensity reduction and an increase in masseter pressure pain thresholds (PPTs), with a large clinical effect. In addition, the results showed an increase in temporalis PPT, with a moderate clinical effect. MA included two studies on cervical MT vs cervico-craniomandibular MT interventions and showed statistically significant differences in pain intensity reduction and pain-free maximal mouth opening, with a large clinical effect. CONCLUSIONS: Cervical MT treatment is more effective in decreasing pain intensity than placebo MT or minimal intervention, with moderate evidence. Cervico-craniomandibular interventions achieved greater short-term reductions in pain intensity and increased pain-free MMO over cervical intervention alone in TMD and headache, with low evidence.

Efficacy of Physical Therapy on Nociceptive Pain Processing Alterations in Patients with Chronic Musculoskeletal Pain: A Systematic Review and Meta-analysis.

INTRODUCTION: Chronic musculoskeletal pain is a major health, social, and economic problem. Most of the subjects who suffer from chronic musculoskeletal pain present processes of central sensitization. Temporal summation and conditioned pain modulation are the two most commonly used clinical measures of this. The objective of this review is to evaluate the effects of physical therapy on temporal summation (TS) and conditioned pain modulation (CPM) in patients with chronic musculoskeletal pain. METHODS: This is a systematic review and meta-analysis. We searched the MEDLINE, EMBASE, CINAHL, EBSCO, PubMed, PEDro, Cochrane Collaboration Trials Register, Cochrane Database of Systematic Reviews, and SCOPUS databases. Different mesh terms and key words were combined for the search strategy, with the aim of encompassing all studies that have used any type of physical therapy treatment in patients with chronic musculoskeletal pain and have measured both TS and CPM. RESULTS: Eighteen studies remained for qualitative analysis and 16 for quantitative analysis. Statistically significant differences with a 95% confidence interval (CI) were obtained for TS (-0.21, 95% CI = -0.39 to -0.03, Z = 2.50, P = 0.02, N = 721) and CPM (0.34, 95% CI = 0.12 to 0.56, Z = 2.99, P = 0.003, N = 680) in favor of physical therapy as compared with control. Manual therapy produces a slight improvement in TS, and physical therapy modalities in general improve CPM. No significant differences between the subgroups of the meta-analysis were found. The methodological quality of the studies was high. CONCLUSIONS: Physical therapy produces a slight improvement in central sensitization (CS)-related variables, with TS decreased and CPM increased when compared with a control group in patients with CMP. Only significant differences in TS were identified in the manual therapy subgroup.

Effectiveness of motor imagery and action observation training on musculoskeletal pain intensity: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Movement representation techniques such as motor imagery (MI) and action observation (AO) could play an important role in the field of rehabilitation of patients with musculoskeletal pain; however, the effects of these tools on clinical pain remain unclear. Our objective is therefore to develop a systematic review and meta-analysis of the effects of MI and AO regarding the pain intensity on patients with musculoskeletal pain. DATABASES AND DATA TREATMENT: MEDLINE, EMBASE, CINAHL and Google Scholar were searched. Last search was run on July 2019. Meta-analysis was conducted to determine the effectiveness on pain intensity in patients with post-surgical pain or chronic pain, and GRADE was used to rate the quality, certainty and applicability of the evidence. RESULTS: A total of 10 studies were included. AO or MI were compared versus usual rehabilitation care. The meta-analysis showed statistically significant differences in MI and AO interventions in patients with pain after surgery in six studies, with a large clinical effect (n = 124; SMD = -0.84; 95% CI: -1.47 to -0.21). In patients with chronic pain, results showed statistically significant differences in MI and AO interventions in three studies, with a large clinical effect (n = 83; SMD = -2.14; 95% CI: -3.81 to -0.47). Risk of bias, imprecision and inconsistency decreased the GRADE level of evidence. CONCLUSIONS: There was very low-quality evidence regarding the effects of movement representation techniques intervention (AO and MI) on pain intensity in patients with post-surgical pain. In addition, there was very low-quality evidence regarding the effects of MI and AO interventions on chronic pain. SIGNIFICANCE: Movement representation techniques in combination with usual care are capable of producing a decrease in pain intensity compared with conventional treatment, in both post-surgical and chronic pain. However, the very low-quality evidence found regarding these techniques showed that more research is needed for their application in a clinical context.
