Comparison of anti-gravity treadmill training and traditional treadmill training in patients with moderate to severe knee osteoarthritis: A randomized controlled trial.

Aerobic exercise is recommended to alleviate pain and protect the joint for patients with advanced knee osteoarthritis, however, its clinical implementation is challenging due to the potential for exacerbating pain. The study aimed to compare the effects of anti-gravity treadmill training with traditional treadmill training in patients with advanced knee osteoarthritis. This single-blinded randomized-controlled trial included 30 women with knee osteoarthritis. All participants received hotpack, transcutaneous electrical nerve stimulation, and therapeutic ultrasound. Additionally, group 1 received anti-gravity treadmill, while group 2 received traditional treadmill training. Group 3 served as the control. The interventions were administered three-times a week for eight-weeks. The visual analogue scale (VAS) pain, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), six-minute-walk-test distance (6MWD), and femoral cartilage thickness were evaluated at baseline and weeks 4 and 8. VAS-pain significantly reduced over time in both anti-gravity (P < 0.001) and control (P = 0.004) groups. The anti-gravity group also showed significant improvements in WOMAC-pain (P = 0.008), WOMAC-total (P = 0.048), and 6MWD (P < 0.001). Post-hoc analysis indicated significant time (P < 0.001, effect size, ηp2 = 0.682) and interaction (P = 0.006, ηp2 = 0.271) effects on VAS, with no significant between-group differences. Femoral cartilage thickness showed no significant between-group differences, except within-group differences in the treadmill group (P = 0.037). Anti-gravity treadmill training significantly improved pain, functionality, and functional capacity in patients with knee osteoarthritis, while traditional treadmill resulted in a reduction in femoral cartilage thickness. Further research should investigate long-term outcomes and more diverse populations. NCT05319964.

Effect of Intravenous Iron on Functional Capacity in Patients with Ischemic Cardiomyopathy

Background: Iron deficiency is common in heart failure with reduced ejection fraction. Intravenous (IV) iron supplementation has been found to reduce morbidity in heart failure. However, the effect of IV iron on Bangladeshi patients with heart failure are not known. Objects: The study was done to see the effect of IV iron on functional capacity in Bangladeshi patients with ischaemic cardiomyopathy (ICM) and iron deficiency. Methodology: In this quasi-experimental study, out of 80 hospitalized patients with ICM and iron deficiency, 40 were given IV ferric carboxymaltose (FCM) in addition to standard therapy of heart failure, while another 40 were randomized to standard therapy alone. Primary outcome measure was changes in six-minute walk test (6MWT) distance, while secondary outcome measures were changes in New York Heart Association (NYHA) functional class, left ventricular ejection fraction (LVEF) and plasma NT-proBNP at Weeks 4 and 12. Results: 6MWT distance improved significantly in patients receiving IV iron therapy compared to the patients not receiving IV iron. LVEF improved and plasma NT-proBNP decreased significantly in IV irontreated patients than in patients receiving standard therapy. However, improvement in NYHA functional class was not statistically significant. Conclusion: In Bangladeshi patients with ICM and iron deficiency, IV FCM on top of standard heart failure therapy was associated with improved functional capacity.

A meta-analysis of the efficacy and safety of exercise-based cardiac rehabilitation in patients with left ventricular assist devices

Abstract Background Left Ventricular Assist Devices (LVADs) and heart transplantation stand out as the two well-established and effective therapeutic approaches for managing patients with advanced heart failure. Exercise-based cardiac rehabilitation (EBCR) has been demonstrated to improve functional capacity in patients with LVAD. Purpose We aim to assess the efficacy and safety of EBCR in patients with LVAD. Also, to compare high-intensity (HIT) versus moderate-intensity (MIT) EBCR regimens in patients with LVAD. Methods A systematic review and meta-analysis synthesizing evidence from randomized controlled trials (RCTs) studies obtained from PubMed, Embase Cochrane, Scopus, and WOS until January 2024. We used the fixed-effects model to report dichotomous outcomes using risk ratio (RR) and continuous outcomes using standardized mean difference (SMD) with a 95% confidence interval (CI). Results Six RCTs with 160 patients were included. There was no significant difference between EBCR and standard care regarding peak VO2 change [SMD: 0.24 with 95% CI (-0.14, 0.62), P= 0.21] and six-minute walk distance (6-MWD) change [SMD: 0.28 with 95% CI (-0.11, 0.66), P= 0.16]. Also, there was no significant difference between HIT and MIT exercise regarding peak VO2 change [SMD: 0.20 with 95% CI (-0.41, 0.82), P= 0.52] and 6-MWD change [SMD: 0.07 with 95% CI (-0.54, 0.69), P= 0.81]. Moreover, EBCR was associated with a significant decrease in the incidence of any adverse events when compared to usual care with [RR: 0.80 with 95% CI (0.65, 0.99), P= 0.04], while there was no significant difference between HIT and MIT exercise regarding the incidence of any adverse events [RR: 0.38 with 95% CI (0.02, 9.22), P= 0.55]. Conclusion EBCR did not improve functional capacity in patients with LVAD, with no significant effect on peak VO2 or 6-MWD.

Achieving theorical cardiorespiratory fitness is associated with high-volumen training in a phase II cardiac rehabilitation program

Abstract Background and Puropose Cardiac Rehabilitation (CR) is an interdisciplinary therapeutic program with demonstrated success rates in reducing cardiovascular outcomes. To obtain these benefits, it is important to achieve a level of cardiorespiratory fitness (CRFIt) that should be close to the ideal according to age and gender (theorical). The best way to measure it, is through VO2p, or with its surrogate value in METs-load. In our Phase II CR program, both aerobic and strength training is supervised 3 times per week, but emphasis is placed on weekly aerobic training volume (TVol) for a sufficient dose, in order to guarantee outcomes. Our hypothesis is that with adequate TVol, CRFit will be achieved at ideal levels (theorical). The aim of the study is to evaluate the safety and achievement in CRFit measured by METs-load in patients with heart disease during a high-volume Phase II CR program. Methods Quasi-experimental study of a comprehensive Phase II CR program in which patients were evaluated by initial and final exercise testing. Depending on the result, they were assigned for 4-6 weeks (4 to those patients with &amp;gt;5METs and 6 to those with &amp;lt;5METs) to 3 weekly concurrent training sessions (30 mins of aerobic at 70-85% of their heart rate reserve plus strength training), in addition to the corresponding educational, nutritional and psychological intervention. TVol was calculated by METs/week (METs-minute obtained by ergo or treadmill multiplied by 90 minutes). Progressions were made to achieve a weekly program average TVol&amp;gt;500 METs/week according to guidelines recomendations. An adverse event was defined as malignant ventricular arrhythmias, cardiorespiratory arrest, or death. Results A population of 522 patients was analyzed, 72% men, average age of 58.8 years (+-0.59), with coronary ischemic disease, heart failure and cardiomyopathies as the most common heart diseases. Regarding the average theorical METs (8.23, +-0.6), our patients achieved final average METs of 10.2 (+-0.26) and 90.02% (+-0.53) of attendace (Figure 1). The average of TVol were 637.4 (+-37.35) METs/week. The differential between the initial and final METs (Delta1) was correlated by Spearman with the differential between the final METs and its theorical (Delta2) and a significant moderate correlation was found (r=0.32 Spearman, p &amp;lt;0.001). TVol and Delta2 shows a strong and significant correlation (r=0.72 Spearman, p&amp;lt;0.001) (Figure 2). No adverse events were reported in any of the training sessions. Conclusion The Phase II CR program with concurrent training only 3 times per week but with TVol&amp;gt;600 METs/week is safe and guarantees a CRFit above the ideal level (theorical). We recommend to measure and fullfill training volume as a strategy to achieve promising results in exercise tolerance and functional capacity in patients with heart disease.

Prognostic role of exercise stress echocardiography in asymptomatic severe aortic stenosis

Abstract Background Guidelines recognize the role of exercise stress testing in evaluating functional capacity in patients with asymptomatic severe aortic stenosis (AS). The study aimed to identify the prognostic role of exercise stress echocardiography (ESE) in asymptomatic severe AS. Methods We enrolled 153 asymptomatic patients (70±13 years; 88 male, 57%) with severe AS, aortic valve area (AVA) &amp;lt;1.0 cm2, mean aortic gradient ≥ 40 mmHg, ejection fraction (EF) ≥55%. All were referred for ESE in 7 quality-controlled centers from 5 countries. Rest and ESE assessment also included global longitudinal strain (GLS) and left atrial volume index (LAVI). B-lines were assessed by LUS with the 4-site simplified scan of the third intercostal space. A 4-point ESE score was based on 4 parameters (0 for normal, 1 for abnormal), with the following pre-determined cutoffs of abnormality: ∆-maximal aortic gradient (MAG) ≥20 mmHg; GLS at peak ≤ 19%, according to receiver operating characteristics curve analysis, stress B-lines ≥2; stress LAVI ≥ 34 mL/m2. Follow-up was completed in 142/153 patients (92%). Results At rest, AVA was 0.85±0.14 cm2, maximal aortic gradient: 79±14 mmHg, and peak aortic velocity: 4.42 ± 0.41 m/s. Mean EF at rest: 63.4±5.3% During a median follow-up of 1802 days (IQ range 651-2302), 41 events occurred in 39 patients: 15 all-cause deaths, 17 acute HF, 1 stroke, 1 myocardial infarction, and 7 coronary revascularization. Patients experiencing events displayed a greater increase in MAG during peak ESE, more B-lines with exercise, greater degree of LAVI dilation with exercise and slightly lower GLS compared to those without events (Table). Increase in ESE score was associated with a significant rise (p=0.001) in event incidence from score 0 (n=0/13, 0%) to score 1 (n=2/21, 9.5%), score 2 (n=10/42, 23.8%), and ≥3 (n=27/66, 40.9%), see figure. Conclusions In asymptomatic severe AS cases with preserved LV EF, comprehensive ESE provides early marker of potential cardiac decompensation at follow-up. The composite ESE index, including MAG, GLS, LAVI, and B-lines, holds promise as a prognostic predictor.TableFigure

Effect of Pilates exercises on pulmonary function, respiratory muscle strength, and functional capacity in patients with inhalation injury after flame thermal burn: A prospective randomized controlled trial

BackgroundInhalation injury is an acute respiratory tract injury that occurrs by inhalation of smoke, toxic gases, or steam. Early management is needed to reduce its mortality and morbidity. The purpose of this study was to ascertain whether Pilates training could help burn patients with inhalation injury after flame thermal burn in increasing pulmonary function, respiratory muscle strength, and functional ability. MethodsIn this prospective, randomized, controlled trial, sixty participants (26 males and 34 females) with inhalation injury and deep partial-thickness flame burns of 30–40 % total body surface area (TBSA) were randomized in blocks of four, with a 1:1 allocation ratio into two groups: Group A (Pilates Group); received Pilates training plus conventional physical therapy program, and Group B (Control Group); received conventional physical therapy program only. This study was conducted at the Faculty of Physical Therapy's outpatient clinic, Cairo University, 3 sessions/week for 12 weeks. The primary outcome measure was the forced vital capacity (FVC) measured by a spirometer, while the secondary outcome measures were peak expiratory flow rate (PEFR), forced expiratory volume in 1 s (FEV1), FEV1/FVC% assessed by a spirometer, strength of respiratory muscles (maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) assessed by the digital manovacuometer, and the functional capacity evaluated by 6-Minute Walk Test (6-MWT). ResultsA two-way mixed-design MANOVA was used to analyze the results within and between groups. There were no significant differences in demographic data between groups (P > 0.05). There were significant differences in all variables after treatment in group A compared with group B; FVC (95 % CI: 0.38, 1.13) (P = 0.001), FEV1 (95 % CI: 0.39, 0.97) (P = 0.001), FEV1/FVC % (95 % CI: 1.90, 17.19) (P = 0.02), PEFR (95 % CI: 0.47, 0.99) (P = 0.001), MIP (95 % CI: 5.12, 11.44) (P = 0.001), MEP (95 % CI: 2.57, 8.24) (P = 0.001), 6-MWT (95 % CI: 27.22, 54.96) (P = 0.001), FVC (% predicted) (95 % CI: 3.58, 12.58) (P = 0.001), FEV1 (% predicted) (95 % CI: 1.21, 11.11) (P = 0.02), PEFR (% predicted) (95 % CI: 1.33, 10.83) (P = 0.01), MIP (% predicted) (95 % CI: 2.26, 11.72) (P = 0.001) and MEP (% predicted) (95 % CI: 1.33, 10.37) (P = 0.01). ConclusionThe current study demonstrated that a Pilates exercise program in addition to a traditional physical therapy program for 12 weeks significantly improved the pulmonary function (FVC, FEV1, PEFR and FEV1/FEV), strength of respiratory muscles (MIP and MEP), and functional capacity (6-MWT) in patients with inhalation injury after flame burns. These results underscore the importance of including Pilates exercises in the rehabilitation plan for burn patients with inhalation injury. Future studies are needed to evaluate the effect of Pilates exercises on other degrees and TBSA of burn, long-term follow up, and to measure cardiopulmonary parameters.

Pulmonary Rehabilitation Program Is an Effective Treatment Approach for Post-COVID-19 Syndrome Patients.

Background/Objectives: Patients with post-COVID-2019 syndrome may have reduced functional capacity and physical activity levels. The pulmonary rehabilitation program (PRP)-an exercise training program-is designed to restore these functions and has been shown to improve dyspnea, exercise capacity, and other measures in these patients. This study aimed to analyze the effects of the RP on post-COVID-19 syndrome patients with respect to objective and subjective functional capacity, balance, and musculoskeletal strength. Methods: A prospective interventional trial was conducted before and after this phase. Patients were referred to the hospital with a confirmed diagnosis of SARS-CoV-2 and subsequently directed to the RP. These patients underwent an 8-week pulmonary rehabilitation program (45-min sessions 3 times/week). Each session consisted of stationary cycle-ergometer and resistance musculoskeletal exercises tailored to individuals' performance. They were evaluated pre- and post-PRP using the maximal handgrip strength (HGS) test, timed up-and-go test, 6-min walk test and its derived variables, and Duke Activity Status Index questionnaire. Results: From 142 hospitalized patients admitted with a diagnosis of SARS-CoV-2 infection, 60 completed the program, with an attendance rate of 85%. Nineteen patients were categorized as severe/critical, with a significantly higher hospital stay, compared to mild/moderate patients, and there were no differences in terms of sex distribution, age, or BMI between groups. Compared to the pre-PRP evaluation, both groups showed significant (p < 0.001) improvements in TUG, HGS, DASI D6MWT, 6MWS, and DSP variables after the PRP conduction. In addition, the groups exhibited similar improvement patterns following PRP (intragroup analysis), with no intergroup differences. Conclusions: RPs promote both objective and subjective functional capacity in patients with post-COVID-19 syndrome, with no difference in improvement regardless of the severity of the initial infection.

New atrio-ventricular indices derived from conventional cine MRI correlate with functional capacity in patients with asymptomatic primary mitral regurgitation

Mitral regurgitation (MR) is associated with morphological and functional alterations of left atrium (LA) and ventricle (LV), possibly inducing LA–LV misalignment. We aimed to: (1) characterize angulation between LA and mitral annulus from conventional cine MRI data and feature-tracking (FT) contours, (2) assess their associations with functional capacity in MR patients, as assessed by oxygen consumption (peak-VO2) and minute ventilation to carbon dioxide production (VE/VCO2) slope, in comparison with MRI LA/LV strain indices. Thirty-two asymptomatic primary MR patients (56 [40; 66] years, 12 women) underwent cardiac MRI resulting in LA/LV conventional FT-derived strain indices. Then, end-diastolic angles were derived from FT LA contours: (1) α, centered on the LA centre of mass and defined by mitral valve extremities, (2) γ, centered on the mitral ring anterior/lateral side, and defined by LA centre and the other extremity of the mitral ring. Cardiopulmonary exercise testing with simultaneous echocardiography were also performed; peak-VO2 and VE/VCO2 slope were measured. While peak-VO2 and VE/VCO2 slope were not correlated to LA/LV strains, they were significantly associated with angles (α: r = 0.50, p = 0.003 and r = − 0.52, p = 0.003; γ: r = − 0.53, p = 0.002 and r = 0.52, p = 0.003; respectively), independently of age and gender (R2 ≥ 0.29, p ≤ 0.03). In primary MR, the new LA/mitral annulus angles, computed directly from standard-of-care MRI, are better correlated to exercise tolerance than conventional LA/LV strain.

Self-image, self-esteem, anxiety, and functional capacity in patients undergoing open-structure rhinoplasty

BackgroundRhinoplasty may improve negative psychological aspects, such as mild to moderate body dysmorphic disorder; however, the repercussions on the self-image and quality of life of patients after the procedure are unknown. ObjectiveTo evaluate self-image, self-esteem, anxiety, and functional capacity of patients undergoing open-structure rhinoplasty. MethodsA primary, analytical, clinical, longitudinal, and prospective study was conducted, which included 30 female patients, aged between 18 and 50 years with elongated nose and nasal hump, who underwent open and structured rhinoplasty. All procedures were performed by a team from the Rhinology DCP/Unifesp. The Rosenberg Self-Esteem Scale - EPM, BDSS, BDD-YBOCS, SF-36, SRQ-20, and STAI (T/E) questionnaires were administered before the surgery and at 6, 12, and 18 months after surgery. ResultsThe results showed statistically significant differences in the Rosenberg scale - EPM (p = 0.017), BDSS (p < 0.001), BDD (p = 0.006), SF-36 (p = 0.041), SRQ-20 (p = 0.012), and STAI-T (p = 0.001) scores in general analyses. Additionally, the statistically significant changes persisted in various stratified postoperative periods. In the qualitative analysis, there was only statistical significance for the classification of the BDSS score, where the “Absent” (absence of body dysmorphism) index increased from 70.0% in the preoperative state to 96.7% in 18 months postoperatively. The “Present” (presence of body dysmorphism) index fell from 30.0% to 3.3% in the same period (p = 0.001). ConclusionOpen-structure rhinoplasty improved the patients’ self-image, self-esteem, anxiety, and mental health.

Diabetic peripheral neuropathy and neuromodulation techniques: a systematic review of progress and prospects.

Neuromodulation for diabetic peripheral neuropathy represents a significant area of interest in the management of chronic pain associated with this condition. Diabetic peripheral neuropathy, a common complication of diabetes, is characterized by nerve damage due to high blood sugar levels that lead to symptoms, such as pain, tingling, and numbness, primarily in the hands and feet. The aim of this systematic review was to evaluate the efficacy of neuromodulatory techniques as potential therapeutic interventions for patients with diabetic peripheral neuropathy, while also examining recent developments in this domain. The investigation encompassed an array of neuromodulation methods, including frequency rhythmic electrical modulated systems, dorsal root ganglion stimulation, and spinal cord stimulation. This systematic review suggests that neuromodulatory techniques may be useful in the treatment of diabetic peripheral neuropathy. Understanding the advantages of these treatments will enable physicians and other healthcare providers to offer additional options for patients with symptoms refractory to standard pharmacologic treatments. Through these efforts, we may improve quality of life and increase functional capacity in patients suffering from complications related to diabetic neuropathy.

Superficial Heat Therapy and Therapeutic Exercise in Individuals with Knee Osteoarthritis

Introduction: Knee Osteoarthritis is a major cause of pain and locomotor disability worldwide. Several physical therapy modalities have been recommended in reviewed clinical guidelines and systematic reviews, such as exercises, and electro and thermotherapy resources. Objective: This study evaluated the influence of the application of superficial heat therapy and/or therapeutic exercise on reducing pain and improving functional capacity in patients with knee osteoarthritis. Methods: 30 patients were divided into three groups (superficial heat, exercises, superficial heat plus exercises) and underwent 10 treatment sessions. Pain intensity was assessed using the visual analog scale; muscle flexibility with Wells’ bank test; strength gain with testing of one maximum repetition; walking time was analyzed with a walking test over a distance of 10 meters; and the Lequesne functional questionnaire was used to assess the functional activities of patients. Results: All treatments performed reduced knee pain. The exercise group showed an improvement in flexibility and quadriceps muscle strength. And the group that received superficial heat and therapeutic exercise showed better performance in time over a fixed distance covered. Conclusions: Therapeutic exercise and superficial thermotherapy performed in isolation showed beneficial effects in individuals with knee osteoarthritis. However, the therapeutic intervention carried out in combination showed better results in all parameters evaluated, suggesting that the clinical treatment can improve the quality of life of these individuals.

Revue à 18 ans de recul minimum, de 10 patients présentant une luxation périlunaire isolée du carpe

Objective: To evaluate, in long-term, the functional abilities and the occurrence of osteoarthritis in patients treated for a posterior perilunate carpal dislocation without bone lesion associated.Patients and method: This was a monocentric retrospective observational study on patients operated on at the University Hospital of Guadeloupe for a posterior perilunate dislocation without bone lesion associated with a minimum of 18 years of follow-up. Ten patients were included with a mean follow-up of 22.8 years. The evaluation criteria were clinical (PRWE, QuickDASH, pain, grip strength, wrist joint mobility, Watson and Reagan tests, Cooney functional score) and radiographic (Gilula curves, carpal height, carpal ulnar translation, scapholunate and radiolunar angles, scapholunate and triquetro-lunar interlines in statics and dynamics, Herzberg’s classification of complications).Results: The average Cooney score was 67.5/100. Mean PRWE and QuickDASH scores were 33.9 and 24.8 respectively. The mean flexion-extension arc on the injured side was 71.5° (66,7% compared to the healthy side). Mean grip strength was 27kg (72,8% compared to the healthy side). The prevalence of osteoarthritis was 60%, with three A types, two A1 types, one B type and four B1 types according to Herzberg.Conclusion: The factors influencing the long-term prognosis are the initial displacement of the lunate, the quality of the reduction and the presence of chronic carpal instability, particularly scapholunate. The high prevalence of osteoarthritis in our series (60%) is apparently not correlated with the functional capacities of patients over the long term.

Cardiac Function and Functional Capacity in Patients With Long COVID: A Comparison to Propensity-Matched Community Controls

Cardiac impairment has been associated with acute COVID-19 since the earliest reports of the pandemic. However, its role in postacute sequelae of COVID-19 ("long COVID") is undefined, and many existing observations about cardiovascular involvement in postacute sequelae of COVID-19 are uncontrolled. To compare the prevalence of cardiac dysfunction in patients with long COVID and noninfected controls from the same community and explore their association with functional capacity. Echocardiography was used to assess cardiac structure and function, including the measurement of global longitudinal strain (GLS), in 190 participants with long COVID. All underwent assessment of functional impairment by subjective (Duke Activity Status Index) and objective tests (6-minute walk test). The 190 participants from the long COVID group were matched with those from 979 patients who underwent the same tests in the pre-COVID-19 era, using a propensity score. The 190 patients with long COVID had similar age and risk factor profiles to those of their matched controls. Left ventricular dimensions and geometry, but not diastolic parameters, were significantly altered in the long COVID group. The long COVID group had subclinical systolic dysfunction (GLS 18.5%±2.6% vs 19.3%±2.7%, P=.005), and more long COVID patients had abnormal (<16%) GLS (13% vs 8%, P=.035). The association of long COVID with abnormal GLS (odds ratio, 1.49 [1.04, 2.45]) was independent of-and had a similar or greater effect size than-age and risk factors. There was no interaction of long COVID with the association of risk factors with GLS. As expected, the long COVID group had significant subjective (<85% predicted METS; 72% vs 5%, P<.001) and objective functional impairment (29% vs 24%, P=.026), but GLS was only weakly associated with both subjective (r=0.30, P=.005) and objective (r=0.21, P=.05) functional impairment. The presence of long COVID was independently associated with subjective (odds ratio=159.7 [95% CI, 61.6-414.2]) and objective functional impairment (odds ratio=2.8 [95% CI, 1.5-5.2]). Impaired GLS and left ventricular dimensions are the echocardiographic features that are overrepresented in long COVID, and this association is similar to and independent of other risk factors. Impaired GLS is weakly associated with functional impairment.

Reductions in functional muscle mass and ability to ambulate in Duchenne muscular dystrophy from ages 4 to 24 years.

Duchenne muscular dystrophy (DMD) results in a progressive loss of functional skeletal muscle mass (MM) and replacement with fibrofatty tissue. Accurate evaluation of MM in DMD patients has not previously been available. Our objective was to measure MM using the D3creatine (D3Cr) dilution method and determine its relationship with strength and functional capacity in patients with DMD over a wide range of ages. Subjects were recruited for participation in a 12month, longitudinal, observational study. Here, we report the baseline data. A 20mg dose of D3Cr dissolved in water was ingested by 92 patients with DMD (ages 4-25years) followed later with a fasting urine sample. Enrichment of D3creatinine was determined by liquid chromatography-mass spectrometry analysis. The North Star Ambulatory Assessment (NSAA) total score was determined for ambulatory participants, and the Performance of Upper Limb (PUL 2.0) total score and grip strength for all participants. We observed a significant age-associated increase in body weight along with a substantial decrease in MM/body weight (%MM). MM and %MM were associated with PUL score (r=0.517, P<0.0001 and r=0.764, P<0.0001 respectively). The age-associated decrease in MM and %MM was strongly associated with ambulatory status. We observed very little overlap in %MM between ambulant and non-ambulant subjects, suggesting a threshold of 18-22% associated with loss of ambulation. MM is substantially diminished with advancing age and is highly related to clinically meaningful functional status. The D3Cr dilution method may provide a biomarker of disease progression and therapeutic efficacy in patients with DMD or other neuromuscular disorders. KEY POINTS: The non-invasive D3creatine dilution method provides novel data on whole body functional muscle mass (MM) in a wide range of ages in patients with DMD and reveals profoundly low functional MM in older non-ambulant patients. The difference in %MM between ambulant and non-ambulant subjects suggests a threshold for loss of ambulatory ability between 18 and 22% MM. The data suggest that as functional MM declines with age, maintaining a lower body weight may help to conserve ambulatory ability.

Evaluation of upper extremity functional capacity and activities of daily living in patients with heart failure: A cross-sectional study

BackgroundConsidering the limitations in activities of daily living (ADL) and the impact of improvements in patients with heart failure (HF), appropriate assessment of upper extremity functional capacity and ADL is important. ObjectivesTo evaluate upper extremity functional capacity and ADL in patients with HF and compare them with healthy controls. MethodsThis study included 30 HF patients and healthy controls. Upper extremity functional capacity was assessed with the 6-Minute Pegboard Ring Test (6PBRT), ADL by the Londrina protocol, exercise capacity by 6-Minute Walk Test (6MWT), peripheral muscle strength by hand dynamometer, and dyspnea by Modified Medical Research Council Scale (MMRC). For performance tests, pre-test (resting) and post-test (after performance) values ​​were also measured. ResultsPatients with HF with ejection fraction ≤50 % and controls were similar in terms of age (52.63±6.2 and 50.03±6.5 years, respectively) and gender (25 females for each group) (p > 0.05). Patients showed a statistically significant increase in total test time in the Londrina protocol and fewer rings moved in 6PBRT (p < 0.0001). The post-test dyspnea (p = 0.03) and pre-test arm fatigue (p < 0.0001) were observed to be higher in patients in the Londrina protocol. There was a statistically significant group by time interaction in the patients’ pre- and post-test lower heart rate (F= 4.80, p = 0.03), post-test dyspnea (p < 0.0001), and post-test arm fatigue (p = 0.005) were observed to be higher in patients in 6PBRT. ConclusionsThe evidence showed a decrease in upper extremity functional capacity in patients with HF. Patients required more time to perform their ADLs compared with healthy controls.

Quality of life and functional capacity in patients after cardiac surgery intensive care unit.

Coronary heart disease and aortic stenosis are prevalent cardiovascular diseases worldwide, leading to morbidity and mortality. Coronary artery bypass grafting (CABG) and surgical aortic valve replacement (SAVR) have therapeutic benefits, including improved postoperative quality of life (QoL) and enhanced patient functional capacity which are key indicators of cardiac surgery outcome. In this article, we review the latest studies of QoL outcomes and functional capacity in patients who underwent cardiac surgery. Many standardized instruments are used to evaluate QoL and functional conditions. Preoperative health status, age, length of intensive care unit stay, operative risk, type of procedure, and other pre-, intra-, and postoperative factors affect postoperative QoL. Elderly patients experience impaired physical status soon after cardiac surgery, but it improves in the following period. CABG and SAVR are associated with increases of physical and mental health and functional capacity in the immediate postoperative and the long long-term. Cardiac rehabilitation improves patient functional capacity, QoL, and frailty following cardiac surgery.

Differential response to preoperative exercise training in patients candidates to cardiac valve replacement

BackgroundThere is lack of evidence regarding safety, effectiveness and applicability of prehabilitation on cardiac surgery population, particularly in patients candidates to cardiac valve replacement. The aim of the study is to assess and compare the effect of a multimodal prehabilitation program on functional capacity in patients with severe aortic stenosis (AoS) and severe mitral regurgitation (MR) proposed for valve replacement surgery.MethodsSecondary analysis from a randomised controlled trial whose main objective was to analyze the efficacy of a 4–6 weeks multimodal prehabilitation program in cardiac surgery on reducing postoperative complications. For this secondary analysis, only candidates for valve replacement surgery were selected. The primary outcome was the change in endurance time (ET) from baseline to preoperative assessment measured by a cycling constant work-rate cardiopulmonary exercise test.Results68 patients were included in this secondary analysis, 34 (20 AoS and 14 MR) were allocated to the prehabilitation group and 34 (20 AoS and 14 MR) to control group. At baseline, patients with AoS had better left systolic ventricular function and lower prevalence of atrial fibrillation compared to MR (p = 0.022 and p = 0.035 respectively). After prehabilitation program, patients with MR showed greater improvement in ET than AoS patients (101% vs. 66% increase from baseline). No adverse events related to the prehabilitation program were observed.ConclusionsA 4–6 week exercise training program is safe and overall improves functional capacity in patients with severe AoS and MR. However, exercise response is different according to the cardiac valve type disfunction, and further studies are needed to know the factors that predispose some patients to have better training response.Trial registrationThe study has been registered on the Registry of National Institutes of Health ClinicalTrials.gov (NCT03466606) (05/03/2018).

Increased physical activity promotes skin clearance, improves cardiovascular and psychological health, and increases functional capacity in patients with psoriasis

AbstractBackgroundPatients with psoriasis are less physically active compared to age‐matched controls, due to psoriasis‐specific barriers, which significantly limits their ability to benefit from health‐promoting levels of physical activity (PA). In addition, long‐term health outcomes for people with psoriasis are poor and include depression, metabolic syndrome and cardiovascular disease (CVD); presenting a significant challenge to healthcare services.ObjectivesWe designed a PA intervention in partnership with patients with psoriasis hypothesising this may have therapeutic utility in the management of psoriasis.MethodsParticipants with chronic plaque psoriasis were recruited to a single‐centre, 20‐week, prospective cohort study. A wrist‐worn accelerometer (GENEActiv Original; Activinsights Ltd) and a hip‐worn pedometer (Onwalk 900; Decathlon Group) were used objectively measure levels of PA. Our 10‐week PA intervention comprised twice weekly 60‐min walks within three different greenspaces in Greater Manchester, each led by a Sports and Exercise Scientist to deliver a pre‐specified volume/dose of activity. During weeks‐11–20 of the study, participants followed independent activities. Clinical evaluation, including assessment of psoriasis severity, cardiometabolic parameters, psychological wellbeing and functional capacity was made at baseline, week‐10 and ‐20.ResultsSixteen patients with psoriasis completed the study. We observed significantly reduced Psoriasis Area and Severity Index at week‐10 (p = 0.01) and ‐20 (p = 0.001) compared to baseline, with 50% of participants achieving PASI‐50 at week‐20. Dermatology Life Quality Index (DLQI) was significantly reduced at week‐20 (p = 0.04), compared to baseline. Significant reduction in blood pressure at week‐10 (systolic: −7.4 mmHg, p = 0.002; diastolic: −4.2 mmHg, p = 0.03) and ‐20 (systolic: −8.8 mmHg, p = 0.001; diastolic: 4.1 mmHg, p = 0.008) was observed and pulse wave velocity was significantly reduced by week‐20 (p = 0.02), suggesting improvement in cardiovascular health. Despite high prevalence of anxiety and depression at baseline, we documented a significant improvement in wellbeing and psychological health. Functional capacity was significantly enhanced following completion of the study.ConclusionIncreasing PA constitutes a promising therapeutic intervention in the management of psoriasis. Evaluation of our intervention in a clinical trial would help determine clinical utility and establish PA guidelines for patients with psoriasis.
