RESUMO
OBJECTIVE: To calculate the minimal clinically important differences (MCIDs) for hand pain intensity and the Boston Carpal Tunnel Questionnaire (BCTQ) in a sample of women with carpal tunnel syndrome (CTS). DESIGN: Secondary analysis of a randomized controlled trial. SETTING: A Hospital Rehabilitation Unit. PARTICIPANTS: One hundred twenty women with clinical and electromyographic diagnosis of CTS who were randomly assigned into 2 groups (N=120). INTERVENTIONS: One group received 3 sessions of manual physical therapy (n=60) and the other group received surgery (n=60). MAIN OUTCOME MEASURES: Mean and the worst pain intensity (numerical pain rate scale, 0-10 points) and functional status and symptoms' severity subscales of the BCTQ questionnaire were assessed before and 1 month after treatment. The Global Rating of Change (GROC) was used as the anchor variable for determining the MCID. RESULTS: A change of 1.5 and 2.5 points in mean and the worst pain intensity represents the MCID for Numerical Pain Rating Scale, whereas a change of 0.23 and 0.64 points in functional status and symptoms' severity represents the MCID for each subscale of the BCTQ. All variables showed acceptable discrimination between patients classified as "improved" and those classified as "stable/not improved" (area under the curve≥0.72). Mean pain intensity (Youden index, 0.53; sensitivity: 73.3%; specificity: 80%) and symptoms' severity (Youden index, 0.69; sensitivity: 90%; specificity: 77.8%) showed the best discriminative ability expressed as a percentage of prediction. Participants classified as "improved" had significantly greater improvements in pain intensity, functional status, and symptoms' severity compared with those classified as "stable/not improved". CONCLUSION: A change of 1.5 and 2.5 points in mean and the worst pain and a change of 0.23 and 0.64 points in functional status and symptoms' severity represents the MCID for pain intensity and BCTQ in women with CTS 1 month after treatment.

BACKGROUND: Multicentre studies focussing on specific long-term post-COVID-19 symptoms are scarce. OBJECTIVE: The aim of this study was to determine the levels of fatigue and dyspnoea, repercussions on daily life activities, and risk factors associated with fatigue or dyspnoea in COVID-19 survivors at long term after hospital discharge. METHODS: Age, gender, height, weight, symptoms at hospitalization, pre-existing medical comorbidity, intensive care unit admission, and the presence of cardio-respiratory symptoms developed after severe acute respiratory syndrome coronavirus 2 infection were collected from patients who recovered from COVID-19 at 4 hospitals in Madrid (Spain) from March 1 to May 31, 2020 (first COVID-19 wave). The Functional Impairment Checklist was used for evaluating fatigue/dyspnoea levels and functional limitations. RESULTS: A total of 1,142 patients (48% women, age: 61, standard deviation [SD]: 17 years) were assessed 7.0 months (SD 0.6) after hospitalization. Fatigue was present in 61% patients, dyspnoea with activity in 55%, and dyspnoea at rest in 23.5%. Only 355 (31.1%) patients did not exhibit fatigue and/or dyspnoea 7 months after hospitalization. Forty-five per cent reported functional limitations with daily living activities. Risk factors associated with fatigue and dyspnoea included female gender, number of pre-existing comorbidities, and number of symptoms at hospitalization. The number of days at hospital was a risk factor just for dyspnoea. CONCLUSIONS: Fatigue and/or dyspnoea were present in 70% of hospitalized COVID-19 survivors 7 months after discharge. In addition, 45% patients exhibited limitations on daily living activities. Being female, higher number of pre-existing medical comorbidities and number of symptoms at hospitalization were risk factors associated to fatigue/dyspnoea in COVID-19 survivors 7 months after hospitalization.

OBJECTIVE: Current evidence suggests that carpal tunnel syndrome (CTS) involves widespread pressure pain sensitivity as a manifestion of central sensitization. This study aimed to quantify mechanisms driving widespread pressure pain hyperalgesia in CTS by using network analysis. DESIGN: Cross-sectional. SETTING: Urban hospital. SUBJECTS: Women with CTS (n=120) who participated in a previous randomized clinical trial. METHODS: Pain intensity, related function, symptom severity, depressive levels, and pressure pain threshold (PPTs) over the median, radial, and ulnar nerves, as well as the cervical spine, the carpal tunnel, and the tibialis anterior, were collected. Network analysis was used to quantify the adjusted correlations between the modeled variables and to determine the centrality indices of each variable (i.e., the degree of connection with other symptoms in the network). RESULTS: The estimated network showed several local associations between clinical variables and the psychophysical outcomes separately. The edges with the strongest weights were those between the PPT over the median nerve and the PPT over the radial nerve (P=0.34), between function and depressive levels (P=0.30), and between the PPT over the carpal tunnel and the PPT over the tibialis anterior (P=0.29 ). The most central variables were PPT over the tibialis anterior (the highest Strength centrality) and PPT over the carpal tunnel (the highest Closeness and Betweenness centrality). CONCLUSIONS: This is the first study to apply network analysis to understand the multivariate mechanisms of individuals with CTS. Our findings support a model in which clinical symptoms, depression, and widespread pressure pain sensitivity are connected, albeit within separate clusters. The clinical implications of the present findings, such as the development of treatments targeting these mechanisms, are also discussed.

OBJECTIVE: To evaluate the effects of muscle dry needling alone or combined with other interventions on post-stroke spasticity (muscle tone), related pain, motor function, and pressure sensitivity. DATABASES AND DATA TREATMENT: Electronic databases were searched for randomized controlled trials including post-stroke patients where at least one group received dry needling and outcomes were collected on spasticity and related pain. Secondary outcomes included motor function and pressure pain sensitivity. Data were extracted by two reviewers. The risk of bias was assessed with the Cochrane Risk of Bias tool, methodological quality was assessed with the Physiotherapy Evidence Database score, and the quality of evidence was assessed by the Grading of Recommendations Assessment, Development, and Evaluation approach. Between-groups mean differences (MDs) and standardized mean differences (SMDs) were calculated. RESULTS: Seven studies (three within the lower extremity, four in the upper extremity) were included. The meta-analysis found significantly large effect sizes of dry needling for reducing spasticity (SMD: -1.01, 95%confidence interval [CI] -1.68 to -0.34), post-stroke pain (SMD -1.01, 95%CI -1.73 to -0.30), and pressure pain sensitivity (SMD 1.21, 95% CI: 0.62 to 1.80) as compared with a comparative group at short-term follow-up. The effect on spasticity was found mainly in the lower extremity (MD -1.05, 95% CI: -1.32 to -0.78) at short-term follow-up. No effect on spasticity was seen at 4 weeks. No significant effect on motor function (SMD 0.16, 95% CI: -0.13 to 0.44) was observed. The risk of bias was generally low, but the imprecision of the results downgraded the level of evidence. CONCLUSION: Moderate evidence suggests a positive effect of dry needling on spasticity (muscle tone) in the lower extremity in post-stroke patients. The effects on related pain and motor function are inconclusive.

OBJECTIVES: To investigate the effects of applying dry needling into a trigger point (TrP) or non-TrP area in people who have suffered a stroke and to investigate if the effects of dry needling are maintained at six-week follow-up. METHODS: A controlled, repeated-measures, crossover, double-blinded randomized trial was conducted. Nineteen patients with hemiparetic shoulder pain after a stroke event were randomly assigned to receive a single multimodal treatment session combined with TrP dry needling or non-TrP dry needling. The neuro-rehabilitation session included modulatory interventions targeting the central nervous system. Spasticity (Modified Ashworth Scale), shoulder pain intensity (numerical pain rate scale, 0-10), and upper extremity function (Motor Evaluation Scale for Upper Extremity in Stroke [MESUPES], Reaching Performance Scale [RPS]) were assessed before (baseline) and one, two, three, four, five, and six weeks after the treatment session by a blinded assessor. All participants received both sessions in a randomized order where they were followed up for six weeks before receiving the opposite treatment and then followed up for another six weeks. RESULTS: Changes in muscle tone (all P > 0.266) and upper extremity function (MESUPES: F = 0.544, P = 0.465; RPS close task: F = 0.820, P = 0.371; RPS far task: 0.830, P = 0.368) were similar after both interventions at all follow-up periods. The decrease in shoulder pain was higher within the TrP dry needling group as compared with the non-TrP dry needling group, particularly at two and four weeks (P = 0.01). CONCLUSIONS: The effect of dry needling on muscle tone (spasticity) and upper extremity function is not related to its application in or outside of a TrP area. The effect of dry needling on shoulder pain was slightly superior when applied over a TrP in poststroke people. These effects were maintained six weeks after treatment.

OBJECTIVE: Our aims were 1) to investigate whether perceived pain extent, assessed from the pain drawing, relates to clinical, psychological, and psychophysical outcomes in women with carpal tunnel syndrome (CTS); 2) to assess differences in pain extent depending on the presence of median or extramedian symptoms; and 3) to investigate differences in pain extent according to severity (minimal, moderate, or severe) or laterality (unilateral or bilateral) of CTS. METHODS: One hundred forty (N = 140) women with CTS completed pain drawings, which were subsequently digitized, allowing pain extent to be calculated. Clinical features including pain intensity (numerical pain rating scale, 0-10) and disability (Boston Carpal Tunnel Questionnaire), psychological features including depression (Beck Depression Inventory), and psychophysical variables (pressure pain and thermal pain thresholds) were assessed. Spearman rho correlation coefficients were used to reveal the correlations between pain extent and other outcomes. Differences in pain extent according to severity (minimal, moderate, severe) or laterality (unilateral, bilateral) and the presence of extramedian symptoms were also evaluated. RESULTS: No significant associations were identified between pain extent and clinical, psychological, or psychophysical outcomes. Women with extramedian symptoms (88%) exhibited a larger (P < 0.001) pain extent (total: 24.2% ± 13.5%) than women with median symptoms (12%; total: 12.2% ± 6.9%). Pain extent was not significantly different depending on the severity or laterality of the symptoms. CONCLUSIONS: Pain extent in the upper extremity was not associated with clinical, psychological, or psychophysical variables and was not related to the severity or laterality of the symptoms in women with CTS.

OBJECTIVE: To assess the influence of clinical, psychological, and psychophysical variables on long-term clinical outcomes after the application of either physical therapy or surgery in women presenting with carpal tunnel syndrome (CTS). METHODS: A secondary analysis of a randomized trial investigating the efficacy of manual therapy including desensitization maneuvers of the central nervous system against surgery in 120 women with CTS was performed. Clinical outcomes including pain intensity, function, or symptom severity were assessed at 6 and 12 months post-intervention. Participants completed at baseline several clinical (pain intensity, function, and symptom severity), psychological (depression), and psychophysical (pressure pain thresholds and pain extent) variables, which were included as predictors. Multiple regression analyses were conducted to assess the relationship between baseline variables and clinical outcomes at 6 and 12 months post-intervention. RESULTS: The regression models indicated that higher scores of each clinical outcome (ie, intensity of pain or symptom severity) at baseline predicted better outcomes at 6 and 12 months post-intervention (from 15% to 65% of variance) in both groups. Lower pressure pain thresholds over the carpal tunnel at baseline predicted poorer clinical outcomes at 6 and 12 months post-intervention (from 5% to 20% of variance) in the physical therapy group, whereas higher depressive symptoms at baseline contributed to poorer outcomes at 6 and 12 months post-intervention (from 5% to 15% of the variance) within the surgery group. CONCLUSION: This study found that baseline localized pressure pain sensitivity and depression were predictive of long-term clinical outcomes in women with CTS following physical therapy or surgery, respectively.

INTRODUCTION: Knee and hip osteoarthritis are two highly prevalent musculoskeletal pain conditions. Unsuccessful rates after hip/knee replacement range from 10% to 20%. Subjects with sensitisation manifestations are vulnerable to worse clinical outcomes. Most studies have analysed outcomes up to 1 year after surgery. The aim of this 2-year longitudinal study will be to evaluate sensory-related, psychological and psychophysical pain sensitisation manifestations and a potential epigenetic biomarker as prognostic clinical outcomes for the development of chronic postoperative pain after knee or hip replacement. METHODS AND ANALYSIS: A prospective longitudinal study with a 2-year follow-up period will be conducted. The prognostic variables will include pain, function, related-disability, anxiety, depression, quality of life, sensitisation-associated symptoms, kinesiophobia, neuropathic pain and catastrophising, and expectative of the intervention will be assessed before surgery. We will also evaluate the presence of the Val158Met polymorphism as a possible epigenetic marker. Clinical outcomes including pain, related-disability and self-perceived satisfaction, sensitisation-associated symptoms and neuropathic pain will be assessed 3, 6, 12, 18 and 24 months after surgery. These variables will be used to construct three prediction models: (1) pain and function, (2) sensitisation-associated symptomatology and (3) neuropathic pain features classifying those patients in responders and non-responders. Data from knee or hip osteoarthritis will be analysed separately. Statistical analyses will be conducted with logistic regressions. ETHICS AND DISSEMINATION: The study has been approved by the Ethics Committee of both institutions involved (Hospital Universitario Fundación Alcorcón (HUFA) 19-141 and Universidad Rey Juan Carlos (URJC) 0312201917319). Participants will sign the written informed consent before their inclusion. Study results will be disseminated through peer-reviewed publications and presentations at scientific meetings.

Carpal tunnel syndrome (CTS) has been traditionally classified as primarily a neuropathic condition with or without pain. Precision medicine refers to an evidence-based method of grouping patients based on their susceptibility to biology, prognosis of a particular disease, or in their response to a specific treatment, and tailoring specific treatments accordingly. In 2021, the International Association for the Study of Pain (IASP) proposed a grading system for classifying patients into nociceptive, neuropathic, or nociplastic phenotypes. This position paper presents data supporting the possibility of subgrouping individuals with specific CTS related-pain into nociceptive, neuropathic, nociplastic or mixed-type phenotypes. Carpal tunnel syndrome is a neuropathic condition but can also be comorbid with a nociplastic pain condition. The presence of extra-median symptoms and the development of facilitated pain processing seem to be signs suggesting that specific CTS cases can be classified as the nociplastic pain phenotype. The clinical responses of therapeutic approaches for the management of CTS are inconclusive. Accordingly, the ability to identify the predominant pain phenotype in patients with CTS could likely be problematic for producing efficient treatment outcomes. In fact, the presence of a nociplastic or mixed-type pain phenotype would explain the lack of clinical effect of treatment interventions targeting the carpal tunnel area selectively. We propose a clinical decision tree by using the 2021 IASP classification criteria for identifying the predominant pain phenotype in people with CTS-related pain, albeit CTS being a priori a neuropathic pain condition. The identification of a nociplastic-associated condition requires a more nuanced multimodal treatment approach to achieve better treatment outcomes.
RESUMO
Knee and hip osteoarthritis are highly prevalent in the older population. Management of osteoarthritis-related pain includes conservative or surgical treatment. Although knee or hip joint replacement is associated with positive outcomes, up to 30% of patients report postoperative pain in the first two years. This study aimed to synthesize current evidence on prognostic factors for predicting postoperative pain after knee or hip replacement. An umbrella review of systematic reviews was conducted to summarize the magnitude and quality of the evidence for prognostic preoperative factors predictive of postoperative chronic pain (>6 months after surgery) in patients who had received knee or hip replacement. Searches were conducted in MEDLINE, CINAHL, PubMed, PEDro, SCOPUS, Cochrane Library, and Web of Science databases from inception up to 5 August 2022 for reviews published in the English language. A narrative synthesis, a risk of bias assessment, and an evaluation of the evidence confidence were performed. Eighteen reviews (nine on knee surgery, four on hip replacement, and seven on both hip/knee replacement) were included. From 44 potential preoperative prognostic factors, just 20 were judged as having high or moderate confidence for robust findings. Race, opioid use, preoperative function, neuropathic pain symptoms, pain catastrophizing, anxiety, other pain sites, fear of movement, social support, preoperative pain, mental health, coping strategies, central sensitization-associated symptoms, and depression had high/moderate confidence for an association with postoperative chronic pain. Some comorbidities such as heart disease, stroke, lung disease, nervous system disorders, and poor circulation had high/moderate confidence for no association with postoperative chronic pain. This review has identified multiple preoperative factors (i.e., sociodemographic, clinical, psychological, cognitive) associated with postoperative chronic pain after knee or hip replacement. These factors may be used for identifying individuals at a risk of developing postoperative chronic pain. Further research can investigate the impact of using such prognostic data on treatment decisions and patient outcomes.
RESUMO
Fatigue and dyspnoea are common post-COVID symptoms. The aim of this study was to apply Sankey plots and exponential bar plots for visualizing the evolution and trajectory of post-COVID fatigue and dyspnoea symptoms in a cohort of previously hospitalized COVID-19 survivors. A total of 1266 previously hospitalized patients due to COVID-19 participated in this multicentre study. They were assessed at hospital admission (T0), 8.4 months (T1), 13.2 months (T2) and 18.3 months (T3) after hospital discharge and were asked about the presence of self-reported fatigue or dyspnoea symptoms. Fatigue was defined as a self-perceived feeling of constant tiredness and/or weakness whereas dyspnoea was defined as a self-perceived feeling of shortness of breath at rest. We specifically asked for fatigue and dyspnoea that participants attributed to the infection. Clinical/hospitalization data were collected from hospital medical records. The prevalence of post-COVID fatigue was 56.94% (n = 721) at T1, 52.31% (n = 662) at T2 and 42.66% (n = 540) at T3. The prevalence of dyspnoea at rest decreased from 28.71% (n = 363) at hospital admission (T0), to 21.29% (n = 270) at T1, to 13.96% (n = 177) at T2 and 12.04% (n = 153) at T3. The Sankey plots revealed that 469 (37.08%) and 153 (12.04%) patients exhibited fatigue and dyspnoea at all follow-up periods. The recovery exponential curves show a decreased prevalence trend, showing that fatigue and dyspnoea recover the following three years after hospitalization. The regression models revealed that the female sex and experiencing the symptoms (e.g., fatigue, dyspnoea) at T1 were factors associated with the presence of post-COVID fatigue or dyspnoea at T2 and T3. The use of Sankey plots shows a fluctuating evolution of post-COVID fatigue and dyspnoea during the first two years after infection. In addition, exponential bar plots revealed a decreased prevalence of these symptoms during the first years after. The female sex is a risk factor for the development of post-COVID fatigue and dyspnoea.
RESUMO
OBJECTIVE: The aim of this clinical trial was to compare the outcomes of the application of ultrasound-guided percutaneous nerve stimulation (PENS) targeting the median nerve versus surgery for improving pain and function in women with CTS. METHODS: In this randomized parallel-group trial (ClinicalTrials.gov, NCT04246216), 70 women with CTS were randomly allocated to either PENS (n = 35) or surgery (n = 35) group. Hand pain intensity (mean pain and the worst pain experienced) was the primary outcome. Functional status and symptoms severity (Boston Carpal Tunnel Questionnaire, BCTQ) and self-perceived improvement (Global Rating of Change, GROC) were the secondary outcomes. Outcomes were assessed at baseline and 1, 3, 6 and 12 months after each intervention. Analysis was performed with intention to treat with mixed ANCOVAs adjusted for baseline outcomes. RESULTS: Analyses showed an adjusted advantage for PENS at 1 (Δ -2.0, 95% CI -2.9 to -1.1) and 3 (Δ -1.4, 95% CI -2.3 to -0.5) months for mean pain, at 1 (Δ -2.2, 95% CI -3.3 to -1.1), 3 (Δ -1.75, 95% CI -2.9 to -0.6) and 6 (Δ -1.7, 95% CI -2.8 to -0.6) months in the worst pain intensity, and at 1 (Δ -0.95, 95% CI -1.1 to -0.8), 3 (Δ -0.55, 95% CI -0.8 to -0.3) and 6 (Δ -0.4, 95% CI -0.6 to -0.8) months in function. Both groups exhibited similar changes in symptom severity. Both groups reported similar improvement at 12 months in all outcomes. Symptoms and function improved in both groups, with PENS leading to better short-term outcomes than surgery. CONCLUSION: This clinical trial confirms that PENS applied with current understanding of pain mechanisms in CTS is as useful as surgery in women with CTS without denervation. The potential placebo effect of both interventions should not be ignored. SIGNIFICANCE: The application of percutaneous nerve stimulation was more effective at short-term, but similar effective at mid and long-term, than surgery in women with carpal tunnel syndrome.

OBJECTIVE: The objective of this study was to investigate whether pressure hypersensitivity over deep tissues is a feature of acute inversion ankle sprain. DESIGN: This is a cross-sectional study. SETTING: No study has previously investigated peripheral and central sensitization mechanisms in a clinical acute pain model such as inversion ankle sprain. PATIENTS: Twenty individuals with unilateral inversion ankle sprain (10 women/10 men, age: 31 ± 7 years) and 19 comparable healthy controls (11 women/8 men, age: 30 ± 6 years) participated in this study. OUTCOMES: Pressure pain thresholds (PPTs) over anterior talofibular, calcaneofibular, and deltoid ligaments; the lateral and medial malleolus; the tibialis anterior muscle; second metacarpal; and median, radial, and ulnar nerves were bilaterally assessed. RESULTS: The analysis of variance (ANOVA) revealed that PPT levels over the affected anterior talofibular (P = 0.048) and calcaneofibular (P = 0.002) ligaments, and over the affected lateral malleolus (P < 0.001) were lower compared with the non-affected side within patients and both sides in controls. The patients also showed bilateral lower PPT levels over the deltoid ligament than controls (P < 0.05). No significant differences for PPT over the medial malleolus; the second metacarpal; the tibialis anterior muscle; and the median, ulnar, radial nerves were found. Significant negative correlations between intensity of ongoing pain and PPT over the anterior talofibular and deltoid ligaments were found: the higher the pain intensity, the lower the PPT. CONCLUSIONS: This study showed the presence of localized pressure pain hypersensitivity over ankle ligaments in patients with unilateral acute inversion ankle sprain, confirming the presence of localized peripheral sensitization.

OBJECTIVES: The purpose of this study is to describe differences in the presence of masseter and temporalis muscle trigger points (TrPs) and jaw opening between individuals with mechanical neck pain and healthy controls. METHODS: Twenty patients with mechanical neck pain (60% women) without symptoms in the orofacial region, aged 20 to 37 years old, and 20 matched controls participated. Temporalis and masseter muscles were examined for the presence of TrPs in a blinded design. Trigger points were considered active if the subject recognized the pain as a familiar symptom, whereas the TrPs was considered latent if the pain was not recognized as a symptom. Jaw opening was assessed with a ruler. RESULTS: A greater number (P < .001) of TrPs in the masticatory muscles were found in patients than in controls. None of the patients or healthy controls recognized the referred pain as familiar; thus, latent rather than active TrPs were found. The distribution of TrPs between groups was different for the masseter (left odds ratio [OR], 3.4; right OR, 8.1; P < .001) and temporalis (left OR, 2.8; right OR, 5.7; P < .001) muscles. Patients with neck pain had smaller jaw opening than controls (P < .001). A negative correlation between active jaw opening and the number of TrPs within the masticatory muscles (r(s) = -0.6; P < .001) was found: the greater the number of TrPs, the smaller the jaw opening. CONCLUSIONS: For the subjects in this study, those with mechanical chronic neck pain had more latent TrPs in the masticatory muscles and reduced jaw opening compared to healthy controls. These findings may suggest the spread of sensitization from the cervical segment to the trigeminal brain stem sensory nuclear complex.

OBJECTIVE: The purpose of this prospective case series was to examine the combined effects of soft tissue mobilization and nerve slider neurodynamic technique on pain and pressure sensitivity in women with chronic carpal tunnel syndrome (CTS). METHODS: Eighteen women with a clinical and electromyographic diagnosis of CTS participated. Patients completed the numerical pain rating scale (NPRS) for current, worst, and lowest pain intensity and underwent pain pressure threshold (PPT) testing over the median, radial, and ulnar nerves; the C5-C6 zygapophyseal joint; the carpal tunnel; and the tibialis anterior muscle. Pain was assessed at baseline and 1-week follow-up, whereas PPT were assessed at baseline and immediately after and 1-week after intervention. Each received soft tissue mobilization and nerve slider neurodynamic technique directed at different anatomical sites of potential entrapment of the median nerve. RESULTS: A decrease in the mean current intensity and worst level of hand pain (P<.01) was found 1 week after the treatment session (mean changes, 2.2±1.1 points). A treatment effect for PPT levels over the C5-C6 zygapophyseal joint (P<.001) was found: PPT increased bilaterally 1 week after the intervention. No other significant changes in PPT levels were found (P>.195). CONCLUSIONS: The application of soft tissue mobilization and neurodynamic technique decreased the intensity of pain but did not change pressure pain sensitivity in this group of women with chronic CTS.

ABSTRACT: This study investigated the association between serological biomarkers at hospital admission with the development of long-term post-COVID pain symptoms in previously hospitalized coronavirus disease, 2019 (COVID-19) survivors. A cohort study including patients hospitalised because of COVID-19 in 1 urban hospital of Madrid (Spain) during the first wave of the outbreak was conducted. Hospitalisation data, clinical data, and 11 serological biomarkers were collected at hospital admission. Participants were scheduled for an individual telephone interview after hospital discharge for collecting data about post-COVID pain symptoms. A total of 412 patients (mean age: 62, SD: 15 years; 46.1% women) were assessed twice, at a mean of 6.8 and 13.2 months after discharge. The prevalence of post-COVID pain symptoms was 42.7% (n = 176) and 36.2% (n = 149) at 6.8 and 13.2 months after hospital discharge. Patients reporting post-COVID pain exhibited a greater number of COVID-19-associated symptoms at hospital admission, more medical comorbidities, higher lymphocyte count, and lower glucose and creatine kinase levels (all, P < 0.01) than those not reporting post-COVID pain. The multivariate analysis revealed that lower creatine kinase and glucose levels were significantly associated, but just explaining 6.9% of the variance of experiencing post-COVID pain. In conclusion, the association between serological biomarkers associated with COVID-19 severity at hospital admission and the development of post-COVID pain is small. Other factors, eg, higher number of COVID-19 onset symptoms (higher symptom load) could be more relevant for the development of post-COVID pain. Because inflammatory biomarkers were not directly analyzed, they may have stronger predictive strengths for the development of post-COVID pain symptoms.

OBJECTIVE: The purpose of this study was to develop a data-driven Bayesian network approach to understand the potential multivariate pathways of the effect of manual physical therapy in women with carpal tunnel syndrome (CTS). METHODS: Data from a randomized clinical trial (n = 104) were analyzed comparing manual therapy including desensitization maneuvers of the central nervous system versus surgery in women with CTS. All variables included in the original trial were included in a Bayesian network to explore its multivariate relationship. The model was used to quantify the direct and indirect pathways of the effect of physical therapy and surgery on short-term, mid-term, and long-term changes in the clinical variables of pain, related function, and symptom severity. RESULTS: Manual physical therapy improved function in women with CTS (between-groups difference: 0.09; 95% CI = 0.07 to 0.11). The Bayesian network showed that early improvements (at 1 month) in function and symptom severity led to long-term (at 12 months) changes in related disability both directly and via complex pathways involving baseline pain intensity and depression levels. Additionally, women with moderate CTS had 0.14-point (95% CI = 0.11 to 0.17 point) poorer function at 12 months than those with mild CTS and 0.12-point (95% CI = 0.09 to 0.15 point) poorer function at 12 months than those with severe CTS. CONCLUSION: Current findings suggest that short-term benefits in function and symptom severity observed after manual therapy/surgery were associated with long-term improvements in function, but mechanisms driving these effects interact with depression levels and severity as assessed using electromyography. Nevertheless, it should be noted that between-group differences depending on severity determined using electromyography were small, and the clinical relevance is elusive. Further data-driven analyses involving a broad range of biopsychosocial variables are recommended to fully understand the pathways underpinning CTS treatment effects. IMPACT: Short-term effects of physical manual therapy seem to be clinically relevant for obtaining long-term effects in women with CTS.

ABSTRACT: This study investigated the prevalence of long-term musculoskeletal post-COVID pain and their risk factors in a large cohort of COVID-19 survivors. A multicenter cohort study including patients hospitalised because of COVID-19 in 5 hospitals of Madrid (Spain) during the first wave of the pandemic was conducted. Hospitalisation and clinical data were collected from medical records. Patients were scheduled for a telephone interview after hospital discharge for collecting data about the musculoskeletal post-COVID pain. Anxiety/depressive levels and sleep quality were likewise assessed. From 2000 patients recruited, a total of 1969 individuals (46.4% women, age: 61 years, SD: 16 years) were assessed on average at 8.4 (SD: 1.5) months after discharge. At the time of the study, 887 (45% women) reported musculoskeletal post-COVID pain. According to the presence of previous pain symptoms, the prevalence of "de novo" (new-onset) musculoskeletal post-COVID pain was 74.9%, whereas 25.1% experienced an increase in previous symptoms (exacerbated COVID-related pain). Female sex (odds ratio [OR]: 1.349, 95% confidence interval [CI]: 1.059-1.720), history of musculoskeletal pain (OR 1.553, 95% CI 1.271-1.898), presence of myalgia (OR 1.546, 95% CI 1.155-2.070) and headache (1.866, 95% CI 1.349-2.580) as COVID-19-associated onset symptoms, and days at hospital (OR 1.013, 95% CI 1.004-1.022) were risk factors associated with musculoskeletal post-COVID pain. In conclusion, musculoskeletal post-COVID pain is present in 45.1% of COVID-19 survivors at 8 months after hospital discharge with most patients developing de novo post-COVID pain. Female sex, history of musculoskeletal pain, presence of myalgia and headache as COVID-19 symptoms at the acute phase, and days at hospital were risk factors associated with musculoskeletal post-COVID pain.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus is associated with a plethora of long-lasting symptoms (long-COVID). The presence of long-COVID symptoms causes decreased functionality. This study described the psychometric properties of the Functional Impairment Checklist (FIC), a disease-specific patient-reported outcome measure (PROM) used for evaluating the functional consequences of SARS in previously hospitalized COVID-19 survivors with long-COVID symptoms. The LONG-COVID-EXP-CM is a multicenter cohort study including patients hospitalized with COVID-19 during the first wave of the pandemic in five hospitals in Madrid. A total of 1969 (age: 61 ± 16 years, 46.4% women) COVID-19 survivors with long-COVID completed the FIC at a long-term follow-up after hospitalization (mean: 8.4 ± 1.5 months). Internal consistency (Cronbach alpha value), reliability (item-internal consistency, item-discriminant validity), construct validity (exploratory factor analysis), floor effect and ceiling effect were calculated. The mean time for fulfilling the FIC was 62 ± 11 s. The Cronbach's alpha values reflecting the internal consistency reliability were 0.864 for FIC-symptoms and 0.845 for FIC-disability. The correlation coefficient between the FIC-symptoms and FIC-disability scale was good (r: 0.676). The ceiling effect ranged from 2.29% to 9.02%, whereas the floor effect ranged from 38.56% to 80.19%. The exploratory factor analysis showed factor loadings from 0.514 to 0.866, supporting good construct validity. Women exhibited greater limitations in all physical symptoms and disability-related domains of the FIC compared with men (all, p < 0.001). Further, younger patients (those aged <45 years) self-reported lower physical symptoms and disability-related domains than older patients. In conclusion, this study indicates that the FIC has good psychometric properties to be used as a specific-disease PROM to measure function and disability in COVID-19 survivors with long-COVID.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus is associated with psychological/emotional disturbances. This study aimed to assess internal consistency, reliability, and construct validity of the Hospital Anxiety and Depressive Scale (HADS), as a patient-reported outcome measure (PROM) for evaluating emotional consequences of SARS-CoV-2 in hospitalized COVID-19 survivors with long COVID. The LONG-COVID-EXP-CM is a multicenter cohort study including patients hospitalized by COVID-19 during the first wave of the pandemic in five hospitals in Madrid. A total of 1969 (age: 61 ± 16 years, 46.5% women) COVID-19 survivors experiencing post-COVID symptoms a mean of 8.4 ± 1.5 months after hospital discharge completed HADS. Internal consistency (Cronbach α), reliability (item-internal consistency, item-discriminant validity), construct validity (confirmatory factor analysis), and floor effect and ceiling effect were calculated. The mean time for fulfilling HADS was 65 ± 12 s. A ceiling effect ranging from 1.99% to 13.74% and a floor effect ranging from 43.05% to 77.77% was observed. Based on the item-scale correlation coefficients, the Cronbach's alpha values reflecting the internal consistency reliability were 0.890 for the anxiety scale (HADS-A) and 0.856 for the depressive scale (HADS-D) The correlation coefficient between HADS-A and HADS-D scores was excellent (r: 0.878). The confirmatory factor analysis revealed that five out of the seven fitness indexes were excellent: CFI = 0.969, NNFI = 0.963; TLI = 0.963; AGFI = 0.951; GFI = 0.972), supporting good construct validity. In conclusion, this study indicates that both anxiety and depressive symptoms scales of HADS had overall good psychometric properties to be used for assessing psychological and emotional stress in COVID-19 survivors with long COVID.
