Effects of home-based exercise with telehealth guidance in lymphoma cancer survivors entering cardio-oncology rehabilitation: rationale and design of the tele@home study.

BACKGROUND: Participation in cardio-oncological rehabilitation is low, and the effects incline to decrease after the initial rehabilitation term. Home-based exercise has the potential to enhance involvement in cardio-oncology rehabilitation and was demonstrated to be feasible, safe, and helpful in increasing short-term cardiorespiratory fitness. The lasting effects on cardiorespiratory fitness and physical activity are uncertain. Hence, a novel approach via telehealth management based on objectively measured exercise at home was proposed. OBJECTIVES: To improve self-monitoring, such as self-confidence, behavioral change, and goal setting for individual exercise, and afterward, increase long-term effects concerning cardiorespiratory fitness. DESIGN: This randomized controlled trial compares a 12-week guided home exercise telehealth intervention with a center-based exercise intervention of the same duration and intensity of exercise in lymphoma cancer survivors entering cardio-oncology rehabilitation after treatment. Participants will be instructed to exercise gradually at 60-85% of their maximum heart rate for 30-50 min 3 times a week. Participants will receive individual remote guidance (feedback about frequency, duration, and exercise intensity) by preferred contact (phone call, text message) once a week based on shared exercise data through the web platform. The primary outcome is a change in cardiorespiratory fitness expressed as maximal oxygen uptake assessed through cardiopulmonary exercise test at baseline, 12 weeks, and 1 year. Secondary objectives are quality of life, muscle strength, body composition, incidence of adverse events, and exercise adherence. This study will determine whether a telehealth model is effective and safe compared to a center-based model in cancer survivors and whether exercise prescriptions are followed by participants. Additionally, an overview of the long-term effectiveness of telehealth cardio-oncology rehabilitation will be provided. This approach aligns with the trend of moving non-complex healthcare services into the patients' home environment. TRIAL REGISTRATION: ClinicalTrials.Gov Identifier: NCT05779605.

Effects of Home-Based Training with Internet Telehealth Guidance in COPD Patients Entering Pulmonary Rehabilitation: A Systematic Review.

Objective: Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death worldwide. Telehealth rehabilitation may offer new opportunities in patient therapy. This systematic review aimed to evaluate the effects of internet-mediated telerehabilitation and compare them with the outcomes of conventional pulmonary rehabilitation in COPD patients. Methods: Electronic databases PubMed, Prospero, Scopus, and Cochrane were searched for randomized controlled trials from January 2005 to December 2021. Two investigators reviewed studies for relevance and extracted study population, methods, and results data. Results: Ten studies were eligible for systematic review from the initial selection (n = 1492). There was considerable heterogeneity in telerehabilitation approaches. Functional exercise capacity and quality of life were assessed in all studies. None of the results were inferior to conventional care. High adherence and high levels of safety were observed. Conclusion: Telerehabilitation in COPD patients is a safe therapy approach that increases and maintains functional exercise capacity and quality of life, making it an equivalent option to conventional outpatient rehabilitation. However, there is currently a lack of a unified approach to the composition of therapy and the use of technology, which needs to be addressed in the future.

A temporal examination of inspiratory muscle strength and endurance in hospitalized COVID-19 patients.

BACKGROUND: The two most common symptoms associated with COVID-19 are dyspnea and fatigue. One possible cause of such symptoms may be inspiratory muscle weakness. OBJECTIVES: The purpose of this study was to examine inspiratory muscle performance (IMP) from intensive care unit discharge (ICUD) to hospital discharge (HD) in patients with COVID-19 hypothesizing that IMP would be markedly depressed at both ICUD and HD. METHODS: IMP was examined at ICUD and HD via the PrO2 device (PrO2 Health, Smithfield, RI) which provided the maximal inspiratory pressure (MIP), sustained MIP (SMIP), inspiratory duration (ID), and fatigue index test (FIT). Patient symptoms were assessed at ICUD, HD, and 1-month post-HD. RESULTS: 30 patients (19 men, 11 women) with COVID-19 were included. The mean±SD age, BMI, and length of ICU and hospital stay was 71±11 yrs, 27.9 ± 6.3 kg/m, 9 ± 6 days, and 26±16 days, respectively. The mean±SD MIP, SMIP, ID, and FIT of the entire cohort at ICUD vs HD were 36±21 vs 40±20 cm H2O, 231±157 vs 297±182 PTU, 8.8 ± 4.2 vs 9.5 ± 4.6 s, and 9.0 ± 9.4 vs 13.1 ± 12.3, respectively, with only SMIP and FIT significantly greater at HD (p=.006 and 0.03, respectively). SMIP at HD was significantly related to resting dyspnea at HD (r=-0.40; p=.02). The SMIP and FIT of men were found to increase significantly from ICUD to HD, but no measure of IMP in the women increased significantly from ICUD to HD. At least one COVID-19-related symptom was present 1 month after HD with the most persistent symptoms being fatigue, cough, and dyspnea in 47%, 40%, and 37% of the patients, respectively. CONCLUSIONS: A significant reduction in IMP exists in patients with COVID-19 at both ICUD and HD and no measure of IMP in women was observed to increase significantly from ICUD to HD. Impaired inspiratory muscle endurance rather than strength was associated with greater dyspnea at HD.

Role of the Inspiratory Muscles on Functional Performance From Critical Care to Hospital Discharge and Beyond in Patients With COVID-19.

OBJECTIVE: The role of inspiratory muscle performance in functional performance in patients with coronavirus disease 2019 (COVID-19) is poorly understood. The purpose of this study was to perform a longitudinal examination of inspiratory and functional performance from intensive care unit (ICU) discharge (ICUD) to hospital discharge (HD) and symptoms at HD and 1 month after HD in patients with COVID-19. METHODS: Thirty patients (19 men, 11 women) with COVID-19 were included. Examination of inspiratory muscle performance at ICUD and HD was performed with an electronic manometer, which provided the maximal inspiratory pressure (MIP) and several other inspiratory measures. Examination of dyspnea and functional performance was performed at ICUD and HD with the Modified Borg Dyspnea Scale and the 1-minute sit-to-stand test (1MSST), respectively. RESULTS: The mean age was 71 (SD = 11) years, the mean length of ICU stay was 9 (SD = 6) days, and the mean length of hospital stay was 26 (SD = 16) days. Most of the patients were diagnosed with severe COVID-19 (76.7%) and had a mean Charlson Comorbidity Index of 4.4 (SD = 1.9), reflecting high comorbidity. The mean MIP of the entire cohort increased minimally from ICUD to HD (from 36 [SD = 21] to 40 [SD = 20] cm H2O), reflecting predicted values for men and women at ICUD and HD of 46 (25%) to 51 (23%) and 37 (24%) to 37 (20%), respectively. The 1MSTS score increased significantly from ICUD to HD (9.9 [SD = 7.1] vs 17.7 [SD = 11.1]) for the entire cohort but remained far below population-based reference values (2.5th percentile) for the majority of patients at ICUD and HD. At ICUD, MIP was found to be a significant predictor of a favorable change in 1MSTS performance (ß = 0.308; odds ratio = 1.36) at HD. CONCLUSION: A significant reduction in inspiratory and functional performance exists in patients with COVID-19 at both ICUD and HD, with a greater MIP at ICUD being a significant predictor of a greater 1MSTS score at HD. IMPACT: This study shows that inspiratory muscle training may be an important adjunct after COVID-19.

Test of incremental respiratory endurance as home-based, stand-alone therapy in chronic obstructive pulmonary disease: A case report.

BACKGROUND: The prevalence of chronic obstructive pulmonary disease (COPD) is increasing worldwide, and at the same time it is associated with increased mortality and reduced quality of life. Efforts to build sustainable rehabilitation approaches to COPD treatment and prevention are crucial. The system of long-term pulmonary rehabilitation care is insufficient. The main reasons for the absence of these outpatient programs are the lack of experience, the lack of interest of insurance companies in secondary prevention programs, and the lack of healthcare facilities in large geographical areas. The possibility of at-home pulmonary rehabilitation models (telemonitoring and telecoaching) could solve this problem. CASE SUMMARY: A 71-year-old man with severe COPD, Global Initiative for Obstructive Lung Diseases stage 3 underwent an 8-wk remotely monitored inspiratory muscle training with a device based on the test of incremental respiratory endurance method. Spirometry, body plethysmography, test of incremental respiratory endurance examination, 6-min walking test, body mass index, airflow obstruction, dyspnea, exercise capacity index, and subjective perception of dyspnea were performed as part of the initial and final examination. The patient performed training at home, and the physiotherapist monitored the patient remotely through a web application that allowed the physiotherapist to evaluate all training parameters in real-time and respond to any problems. After 8 wk of home training, there was a significant increase in all monitored values: maximal inspiratory pressure, a novel parameter sustained maximal inspiratory pressure, forced expiratory volume in 1 s, total lung capacity, forced vital capacity, peak expiratory flow, and inspiratory capacity. There was also an improvement in the perception of dyspnea according to the COPD Assessment Test and a modified Medical Research Council Breathlessness Scale, an increase in exercise tolerance according to the 6-min walking test, and a decrease in the exercise capacity index as a predictor of prognosis. CONCLUSION: Respiratory telerehabilitation was greatly beneficial in a cooperative patient with COPD and may represent an alternative therapeutic approach to the increasing incidence of all lung diseases.

Long-term exercise effects after cardiac telerehabilitation in patients with coronary artery disease: 1-year follow-up results of the randomized study.

BACKGROUND: Home-based cardiac telerehabilitation (HBCT) is a feasible and effective alternative to traditional center-based cardiac rehabilitation (CBCR). Currently, there are only limited studies focusing on a long-term effect of HBCT, which means it is essential to do more research in this study field. AIM: This study aimed at investigating a 1-year effect of a randomized controlled study using Cardiac Rehabilitation through the Global Position System (CR-GPS) compared to outpatient cardiac rehabilitation. Study focused on cardiorespiratory fitness (CRF) and health-related quality of life (HRQL) in patients with coronary heart disease (CAD). DESIGN: A long-term follow-up of a randomized study. SETTING: Patients were enrolled, and the intervention was performed in an outpatient or home-based model. The results were obtained and evaluated in a hospital. POPULATION: Patients who participated in the CR-GPS study were diagnosed with CAD with low to moderate cardiovascular risk. METHODS: Patients enrolled in the study were eligible participants who had previously completed a 12-week HBCT program using a wrist heart rate (HR) monitor or attended a traditional CBCR. Primary outcome was the change in CRF expressed in peak oxygen uptake (pVO2), and the secondary outcomes were self-reported HRQL, objectively measured anthropometric characteristics, and mortality and hospitalization rates. RESULTS: Forty-four patients (76%) completed the long-term follow-up. The average peak of pVO2 was higher after 1-year follow-up in the telerehabilitation group (HBCT 25.5 mL/kg/min compared to the active control group CBCR 23.6 mL/kg/min P=0.047). No statistically significant difference between the two groups was found after long-term follow-up for the parameter HRQL. For both groups, there was a significant improvement in the range of perceptions of general health. There was no death case and no difference in hospitalization rate between the groups. CONCLUSIONS: This study supports the HBCT model. It has been demonstrated that it induces satisfactory long-term effects in pVO2, exercise performance, and perceived general health in CAD patients with low to moderate cardiovascular risk. CLINICAL REHABILITATION IMPACT: Cardiovascular telerehabilitation using wrist HR monitors is a feasible and effective rehabilitation method that can help patients eliminate barriers that prevent them from using CBCR programs. Especially in the current global situation with the COVID-19 pandemic, this topic is becoming increasingly important.

Is the Training Intensity in Phase Two Cardiovascular Rehabilitation Different in Telehealth versus Outpatient Rehabilitation?

Telehealth cardiac rehabilitation (CR) is a feasible and effective alternative to conventional outpatient CR. Present evidence is limited on the comparison of exercise intensity adherence in telehealth and outpatient CR. The purpose of the study was to evaluate and compare training intensity adherence through 12-week phase II CR in telehealth and outpatient CR. A sample of 56 patients with coronary artery disease (CAD) with a mean age of 56.7 ± 7.1 entering comprehensive secondary prevention phase II was randomized into telehealth CR (n = 28) and control outpatient CR (n = 28) groups. The primary outcome was a comparison of training intensity adherence in both CR models and heart rate (HR) response from individual CR sessions, expressed by the HR reserve percentage. As a result, the parameter HR reserve percentage as the total average of the training intensity during the telehealth intervention and the outpatient CR did not differ statistically (p = 0.63). There was no death case, and all severe adverse cases required medical admission throughout an exercise training session in study subjects in both groups. This research evidence demonstrated that the telehealth CR model is similar in training intensities to the conventional outpatient CR in CAD patients with low to moderate cardiovascular risk.

Effect of home-based high-intensity interval training using telerehabilitation among coronary heart disease patients.

INTRODUCTION: Cardiovascular diseases are the world's most common causes of morbidity and mortality in the population, including Central Europe. Cardiac rehabilitation (CR) is an effective preventive approach that includes several core components. Physical training is identified as an integral and essential part of CR. Training can positively influence several cardiovascular risk factors in people diagnosed with coronary heart disease and prevent them from clinical events. Our study aims to research the method of high-intensity interval training (HIIT) in a home environment using telerehabilitation. We assume that the HIIT form of telerehabilitation, using a heart rate monitor as a tool for backing up training data, can improve cardiorespiratory fitness and lead to higher peak oxygen uptake than the traditional moderate-intensity continuous training (MICT). METHODS: This study is designed as a monocentral randomized controlled trial at University Hospital Brno in the Czech Republic. After the coronary heart event, the suitable patients will be randomized (1:1 ratio) and separated into 2 groups: the experimental HIIT group and the control MICT group. Both groups undergo a 12-week telerehabilitation with a 1-year follow-up period. Study participants will be telemonitored during physical training in their home environment via a heart rate monitor and a web platform. Once a week, the patients will give their feedback and motivation by a telephone call.The primary outcome observed will be the effect of intervention expressed by changes in cardiorespiratory fitness. Secondary outcomes will be the health-related quality of life, anxiety, training adherence, body composition, safety, and satisfaction. DISCUSSION: The HIIT is widely researched predominantly in a center-based supervised form. Our study differs from others by the use of telemedicine and smart technologies in home-based settings. Previous home-based cardiac telerehabilitation studies have focused primarily on MICT, which has demonstrated feasibility, and results have shown similar improvements as center-based CR. There is a presumption that HIIT may be superior to MICT. However, it can be complicated to self-dose the method in the home environment. Investigators expect that HIIT research will provide insight into the possibilities of telemedicine feasibility, effect, and limitations of coronary heart disease patients' use at low to moderate cardiovascular risk.

Benefits and effectiveness of using a wrist heart rate monitor as a telerehabilitation device in cardiac patients: A randomized controlled trial.

BACKGROUND: Telerehabilitation in cardiology has the potential to become the alternative to regular outpatient cardiac rehabilitation. Our study focuses on the wrist heart rate monitor as a telerehabilitation device, defines detected limitations, and compares results between home-based and regular outpatient rehabilitation methods, related to physical fitness, quality of life, and training adherence. The study design was a randomized controlled trial. METHODS: Eligible 56 cardiac rehabilitation patients were randomized into a 12-week regular outpatient training group (ROT) and interventional home-based telerehabilitation group (ITG). For both groups, the intensity of the training was prescribed to be performed at 70% to 80% of heart rate reserve for 60 minutes, 3 times a week. The ITG patients started their training with a wrist heart rate monitor in their home environment. These patients received feedback once a week, reflecting data uploaded on the internet application. The ROT patients performed their exercise under the direct supervision of a physical specialist in a regular outpatient clinic. Physical fitness and health-related quality of life were assessed at baseline and after 12 weeks. Training adherence in both groups was determined and compared. RESULTS: Fifty-one patients comleted the intervention (91%); no serious adverse events were recorded. Physical fitness expressed as peak oxygen uptake showed significant improvement (P < .001) in ROT group from 23.4 ±â€Š3.3 to 25.9 ±â€Š4.1 mL/kg/min and (P < .01) in ITG group from 23.7 ±â€Š4.1 to 26.5 ±â€Š5.7 mL/kg/min without significant between-group differences after 12 weeks of intervention. The training adherence between groups was similar. CONCLUSION: Our study shows that telerehabilitation via wrist heart rate monitor could become an alternative kind of cardiac rehabilitation which deserves attention and further analyzing.

Novel versus Traditional Inspiratory Muscle Training Regimens as Home-Based, Stand-Alone Therapies in COPD: Protocol for a Randomized Controlled Trial.

Background: Subjects with COPD frequently develop considerable weakness and deconditioning of the inspiratory musculature, which can be corrected with inspiratory muscle training (IMT). While rehabilitation centers may be able to provide IMT as part of the rather complex management of COPD, there is currently a lack of rehabilitation services in the Czech Republic. Remote IMT may then benefit subjects with COPD who are unable to attend or do not have access to rehabilitation programs. We aim at evaluating the utility of the test of incremental respiratory endurance (TIRE) as an at-home IMT method in subjects with COPD, while comparing the effectiveness of this novel training approach to the outcomes of traditional, threshold loading IMT protocols. Methods/Design: This prospective, randomized controlled trial will comprise 8 weeks of at-home IMT sessions with remote supervision followed by 4 months of unsupervised, independent IMT. Eligible subjects will be randomly assigned to one of the following three distinct home-based IMT protocols: (1) TIRE, (2) Threshold loading, and (3) Sham training. Subjects allocated to the TIRE group will train once daily using an advanced IMT electronic system (PrO2), while the other two groups will receive threshold devices. Study outcomes will include measures of inspiratory muscle strength and endurance, pulmonary function, COPD-specific symptomatology, functional exercise capacity, surrogate markers of mortality risk, mental health status and health-related quality of life. Discussion: While we acknowledge the value of threshold loading IMT protocols, we believe that the TIRE training method has the potential to provide additional clinical benefits in COPD given its sophisticated remote tracking system and ability to modulate all aspects of muscular performance, including not only strength but also endurance, power and work capacity, allowing users to achieve considerably higher inspiratory pressures throughout the full range of inspiration when compared to other more traditionally used IMT methods.

Rationale and design of randomized controlled trial protocol of cardiovascular rehabilitation based on the use of telemedicine technology in the Czech Republic (CR-GPS).

BACKGROUND: Cardiovascular diseases remain the most common causes of death in the world. Instructions for secondary prevention recommend multifaceted approach in cardiovascular diseases risk management. Center-based physical exercise training is considered as an important integral part of cardiac rehabilitation (CR). Despite all recognized benefits CR brings, active interest of patients remains low in many countries, including the Czech Republic. That is why there is a need to focus on more effective patients' participation in CR with respect to their preferences and needs. One of possible approaches is using telemonitoring guidance based on obtaining data via technological equipment during home exercise training. The aim of this study is to compare effectiveness of both center- and home-based exercise training with focus on participants' physical fitness and quality of life. METHODS/DESIGN: This randomized control trial intends to monitor cardiorespiratory health indicators and quality of life of patients diagnosed with a coronary artery disease (CAD) at the University Hospital Brno, Czech Republic. These patients will be randomly separated into 2 groups-a regular outpatient group (ROT) and an intervention training group (ITG). Both groups undergo a 12-week rehabilitation training program. The ROT group will undergo center-based exercise trainings in the hospital and receive feedback and support directly by their coach. The ITG group will be telemonitored during exercise training in their home environment via a wrist sport tester and Internet application.All patients will be supposed to exercise at 70% to 80% of their heart rate reserve obtained from cardiopulmonary exercise test (CPX). The primary outcome is to measure and compare physical fitness values assessed at baseline and after 12 weeks of training. Physical fitness is expressed as peak oxygen uptake assessed by the CPX test. The secondary outcomes are patients, training adherence, and their quality of life. DISCUSSION: This trial focuses on an up-to-date topic. As there have not been any similar trials in the Czech Republic yet, we expect it to bring great benefits not only for our hospital in Brno. In the long term, this method seems to be low-cost for all participants and brings a lot of benefits for those patients, who are for many reasons unable to participate in center-based CR provided by hospitals and other health care centers. Physical exercise therapy brings good results in reducing cardiovascular risk factors and improves its global impact. Thanks to its simplicity, it is expected to increase patients' training adherence as well.
