RESUMEN
OBJECTIVE: Small muscle mass training localized to the quadriceps femoris muscle group has been proposed as an intervention to reverse heart failure-related skeletal muscle impairments. Although this training paradigm has demonstrated efficacy in heart failure, it remains to be evaluated in a conventional clinical context. Hence, the aim of this proposed study is to determine the effects of integrating high-intensity small muscle mass training (HISMT) isolated to the knee extensor muscles within a standard heart failure rehabilitation program. METHODS: This single-blind, randomized controlled trial will aim to recruit 70 participants with heart failure. Participants will be randomized to either (1) standard training: combination of upper and lower extremity cardiovascular and resistance-based exercises, or (2) HISMT plus modified standard training: bilateral knee extensor HISMT and a modified version of the standard training, so that the total volume of work will be similar to standard training alone. The training interventions will be undertaken twice weekly for 12 weeks in an outpatient clinical setting. Outcome measurements will be performed at baseline and after the 12-week intervention period. The primary outcome will be exercise capacity (6-Minute Walk Test), with secondary outcomes being physical performance measures, muscle strength, and health-related quality of life. Data will be analyzed using the intention-to-treat principle. IMPACT: This study will address a gap in the literature regarding the efficacy of small muscle training under routine clinical conditions for individuals with heart failure. The findings will also provide insight into the effects of HISMT within a heart failure rehabilitation program, thus enabling the optimization of exercise prescription for this patient population.

Given the under-utilisation of cardiac rehabilitation despite its benefits, there has been a shift towards alternative delivery models. The recent coronavirus disease 2019 (COVID-19) pandemic has accelerated this shift, leading to a growing interest in home-based cardiac rehabilitation including telerehabilitation. There is increasing evidence to support cardiac telerehabilitation, with studies generally demonstrating comparable outcomes and potential cost-benefits. This review aims to provide a synopsis of the current evidence on home-based cardiac rehabilitation with a focus on telerehabilitation and practical considerations.

PURPOSE: The objective of this study was to describe the psychometric properties and physiological response of the five times sit-to-stand (STST-5) and 60-sec sit-to-stand test (STST-60) in adults with heart failure (HF). METHODS: People with HF enrolled in a 12-wk exercise rehabilitation program completed two STST-5 and two STST-60 as part of their usual baseline and follow-up assessments. Test-retest reliability, validity, and responsiveness of the two STSTs were described. Results were correlated with the 6-min walk test (6MWT) and timed up and go test (TUGT), and rating of perceived exertion and physiological responses were compared between all tests. Feasibility was also reported according to the presence of adverse events and adherence to the protocol. RESULTS: Forty-nine adults with HF participated in this study. Intraclass correlation coefficients of the STST-5 and STST-60 were 0.91 (95% CI, 0.78-0.96) and 0.96 (95% CI, 0.93-0.98), respectively. The STST-60 was strongly associated with both the 6MWT ( r = 0.76) and the TUGT ( rs =-0.77). The STST-5 was strongly associated with the TUGT ( rs = 0.79) and moderately associated with the 6MWT ( rs =-0.70). Rating of perceived exertion and lower limb fatigue were greater in the STST-60 than in the 6MWT ( P < .001) or STST-5 ( P < .001). Adverse events occurred in five participants undertaking the STST-60 and one participant undertaking the STST-5. CONCLUSIONS: The STST-5 and STST-60 are reliable and valid measures of functional exercise capacity in people with HF.

BACKGROUND: Postoperative pneumonia and delayed physical recovery are significant problems after emergency laparotomy. No randomized controlled trial has assessed the feasibility, safety, or effectiveness of intensive postoperative physical therapy in this high-risk acute population. METHODS: The internal pilot phase of the Incidence of Complications after Emergency Abdominal Surgery: Get Exercising (ICEAGE) trial was a prospective, randomized controlled trial that evaluated the feasibility, safety, and clinical trial processes of providing intensive physical therapy immediately following emergency laparotomy. Fifty consecutive patients were recruited at the principal participating hospital and randomly assigned to standard-care or intensive physical therapy of twice daily coached breathing exercises for 2 days and 30 minutes of daily supervised rehabilitation over the first 5 postoperative days. RESULTS: Interventions were provided exactly as per protocol in 35% (78 of 221 patients) of planned treatment sessions. Main barriers to protocol delivery were physical therapist unavailability on weekends (59 of 221 patients [27%]), awaiting patient consent (18 of 99 patients [18%]), and patient fatigue (26 of 221 patients [12%]). Despite inhibitors to treatment delivery, the intervention group still received twice as many breathing exercise sessions and four times the amount of physical therapy over the first 5 postoperative days (23 minutes [interquartile range, 12-29 minutes] vs. 86 minutes [interquartile range, 53-121 minutes]; p < 0.001). One adverse event was reported from 78 rehabilitation sessions (1.3%), which resolved fully on cessation of activity without escalation of medical care. CONCLUSION: Intensive postoperative physical therapy can be delivered safely and successfully to patients in the first week after emergency laparotomy. The ICEAGE trial protocol resulted in intervention group participants receiving more coached breathing exercises and spending significantly more time physically active over the first 5 days after surgery compared with standard care. It was therefore recommended to progress into the multicenter phase of ICEAGE to definitively test the effect of intensive physical therapy to prevent pneumonia and improve physical recovery after emergency laparotomy. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level II.

INTRODUCTION: As COVID-19 restrictions reduce globally, services will determine what components of care will continue via telehealth. We aimed to determine the clinician, service, and system level factors that influence sustained use of telehealth and develop a framework to enhance sustained use where appropriate. METHODS: This study was conducted across 16 allied health departments over four health service facilities (Brisbane, Australia). It used a multi-method observational study design, involving telehealth service activity data from hospital administrative databases and qualitative interviews with allied health staff (n = 80). Data were integrated and analysed using Greenhalgh's Non-adoption, Abandonment, Scale-up, Spread, and Sustainability framework. RESULTS: Increased telehealth use during the peak COVID period reverted to in-person activity as restrictions eased. Telehealth is unlikely to be sustained without a clear strategy including determination of roles and responsibilities across the organisation. Clinician resistance due to forced adoption remains a key issue. The main motivator for clinicians to use telehealth was improved consumer-centred care. Benefits beyond this are needed to sustain telehealth and improvements are required to make the telehealth experience seamless for providers and recipients. Data were synthesised into a comprehensive framework that can be used as a blueprint for system-wide improvements and service enhancement or redesign. DISCUSSION: Sustainability of telehealth activity beyond the peak COVID period is unlikely without implementation strategies to address consumer, clinician, service, and system factors. The framework can inform how these strategies can be enacted. Whilst developed for allied health disciplines, it is likely applicable to other disciplines.
RESUMEN
BACKGROUND: With the change in healthcare to one that adopts a greater reliance on remote delivery, guidance regarding functional exercise testing, either in-person in the home or performed remotely, is urgently needed for people with cardiac conditions. OBJECTIVES: To identify functional exercise tests that have been conducted in the home or remotely in patients with cardiac conditions. DATA SOURCES: A search was undertaken across four electronic databases and grey literature for English language publications without time restrictions. STUDY ELIGIBILITY CRITERIA: Studies of any designs were selected if they reported an exercise test conducted at home or remotely in patients with cardiac conditions. STUDY APPRAISAL AND SYNTHESIS: Studies were independently screened and graded by two reviewers according to the Downs and Black checklist. A narrative synthesis of the included studies was undertaken. RESULTS: Five studies (six articles) were included, with a total of 438 patients with cardiac conditions. Tests used at home or remotely were the 6-minute walk test (6MWT, five studies) and the timed up and go test (one study). No studies reported the use of step tests in the home or remotely. The 6MWTs were administered via a smartphone application, rope, videoconferencing and accelerometer and proved to be feasible, valid and reliable. CONCLUSIONS: Despite a marked demand for home-based exercise programs, the 6MWT remains the most commonly administered functional exercise test for people with cardiac conditions. Surprisingly few studies have explored alternative tests for this patient population that may be more suitable for home or remote performance. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO: CRD42020219512.

BACKGROUND: Whilst home-based telerehabilitation has been shown non-inferior to traditional centre-based rehabilitation in patients with chronic heart failure, its economic sustainability remains unknown. This study aimed to investigate the cost-utility of a home-based telerehabilitation program. METHODS: A comparative, trial-based, incremental cost-utility analysis was conducted from a health care provider's perspective. We collected data as part of a multi-centre, two-arm, non-inferiority, randomised controlled trial with 6 months follow-up. There were 53 participants randomised to either a telerehabilitation program (consisting of 12 weeks of group-based exercise and education delivered into the home via online videoconferencing) or a traditional centre-based program. Health care costs (including personnel, equipment and hospital readmissions due to heart failure) were extracted from health system records, and calculated in Australian dollars using 2013 as the base year. Health utilities were measured using the EuroQol five-dimensional (EQ-5D) questionnaire. Estimates were presented as means and 95% confidence intervals (CIs) based on bootstrapping. Costs and utility differences were plotted on a cost-effectiveness plane. RESULTS: Total health care costs per participant were significantly lower in the telerehabilitation group (-$1,590, 95% CI: -2,822, -359) during the 6 months. No significant differences in quality-adjusted life years (0, 95% CI: -0.06, 0.05) were seen between the two groups. CONCLUSIONS: Heart failure telerehabilitation appears to be less costly and as effective for the health care provider as traditional centre-based rehabilitation.

OBJECTIVE: To elicit patients' preferences for cardiac rehabilitation(CR). METHODS: A Discrete Choice Experiment was used to quantify patients' preferences for the delivery of CR. This survey-based method elicited the relative importance of different characteristics of a program. RESULTS: 200 in-patients eligible to attend CR completed the survey. Over half of the patients strongly preferred a centre-based compared to a home-based program. Many but not all preferred a program starting within two rather than six weeks of discharge and exercise delivered in a group rather than individual setting, with exercise via the internet using telehealth strongly disliked. Some respondents preferred lifestyle information delivered one-to-one by a health professional, and there was an overall preference against delivery by smart phone Apps. Some preferred a program out of rather than within working hours and a shorter program (four weeks compared to eight weeks). CONCLUSIONS: This study provides further insight into patient preferences for a CR program. Although the strongest preferences were for centre-based programs with healthcare professionals facilitating exercise classes and one-on-one education, it is important to offer flexible delivery as one approach will not suit everyone. PRACTICE IMPLICATIONS: There is the potential to improve CR programs by focusing on patient preferences.

OBJECTIVES: To describe patient experiences and perspectives of a group-based heart failure (HF) telerehabilitation program delivered to the homes via online video-conferencing. BACKGROUND: Limited information currently exists on patient experiences of telerehabilitation for HF. Patient feedback and end-user perspectives provide important information regarding the acceptability of this new delivery model which may have a substantial impact on future uptake. METHODS: We used mixed-methods design with purposive sampling of patients with HF. We used self-report surveys and semi-structured interviews to measure patient experiences and perspectives following a 12-week telerehabilitation program. The telerehabilitation program encompassed group-based exercise and education, and were delivered in real-time via videoconferencing. Interviews were transcribed and coded, with thematic analysis undertaken. RESULTS: Seventeen participants with HF (mean age [SD] of 69 [12] years and 88% males) were recruited. Participants reported high visual clarity and ease of use for the monitoring equipment. Major themes included motivating and inhibiting influences related to telerehabilitation and improvement suggestions. Participants liked the health benefits, access to care and social support. Participants highlighted a need for improved audio clarity and connectivity as well computer training for those with limited computer experience. The majority of participants preferred a combined face-to-face and online delivery model. CONCLUSION: Participants in this study reported high visual clarity and ease-of-use, but provided suggestions for further improvements in group-based video telerehabilitation for HF.

QUESTION: Is a 12-week, home-based telerehabilitation program conducted in small groups non-inferior to a traditional centre-based program in terms of the change in 6-minute walk distance? Is the telerehabilitation program also non-inferior to a centre-based program in terms of functional capacity, muscle strength, quality of life, urinary incontinence, patient satisfaction, attendance rates, and adverse events? DESIGN: Randomised, parallel, non-inferiority trial with concealed allocation, intention-to-treat analysis and assessor blinding. PARTICIPANTS: Patients with stable chronic heart failure (including heart failure with reduced or preserved ejection fraction) were recruited from two tertiary hospitals in Brisbane, Australia. INTERVENTION: The experimental group received a 12-week, real-time exercise and education intervention delivered into the participant's home twice weekly, using online videoconferencing software. The control group received a traditional hospital outpatient-based program of the same duration and frequency. Both groups received similar exercise prescription. OUTCOME MEASURES: Participants were assessed by independent assessors at baseline (Week 0), at the end of the intervention (Week 12) and at follow-up (Week 24). The primary outcome was a between-group comparison of the change in 6-minute walk distance, with a non-inferiority margin of 28m. Secondary outcomes included other functional measures, quality of life, patient satisfaction, program attendance rates and adverse events. RESULTS: In 53 participants (mean age 67 years, 75% males), there were no significant between-group differences on 6-minute walk distance gains, with a mean difference of 15m (95% CI -28 to 59) at Week 12. The confidence intervals were within the predetermined non-inferiority range. The secondary outcomes indicated that the experimental intervention was at least as effective as traditional rehabilitation. Significantly higher attendance rates were observed in the telerehabilitation group. CONCLUSION: Telerehabilitation was not inferior to a hospital outpatient-based rehabilitation program in patients with chronic heart failure. Telerehabilitation appears to be an appropriate alternative because it promotes greater attendance at the rehabilitation sessions. TRIAL REGISTRATION: ACTRN12613000390785. [Hwang R, Bruning J, Morris NR, Mandrusiak A, Russell T (2017) Home-based telerehabilitation is not inferior to a centre-based program in patients with chronic heart failure: a randomised trial.

BACKGROUND: A variety of educational interventions have been implemented to assist patients with heart failure (HF) to maintain their own health, develop self-care behaviors, and decrease readmissions. The most effective approach to education has yet to be established. OBJECTIVE: The aim of this study is to determine the effectiveness of a multimedia educational intervention for patients with HF in reducing hospital readmissions. Secondary outcomes include changes in knowledge and self-care behaviors. METHODS: A randomized controlled trial in a large tertiary referral hospital in Australia has recruited 200 patients and will follow them for 12 months. Patients diagnosed with HF have been randomly allocated 1:1 to either usual education or a multimedia educational intervention. Framed by the principles of adult learning, this individualized intervention was delivered face to face by a specialized HF nurse, with a targeted educational assessment and subsequent development of an educational plan. The multimedia approach combined viewing a DVD and verbal discussion supported by a written manual. The teach-back strategy at the conclusion of the intervention evaluated the patient's learning through 5 key questions about self-management of HF. Readmissions are assessed at 28 days, 3 months, and 12 months. Knowledge and self-care behavior are assessed at baseline, 3 months, and 12 months. CONCLUSIONS: This study evaluates the effectiveness of a targeted multimedia educational intervention. Study results may inform the design of in-hospital education for HF patients.

Introduction This study aimed to determine the validity and reliability of video-based telerehabilitation assessments in patients with heart failure. Methods Seventeen consecutive participants (mean age 69 years, SD 12 years and 88% males) undertook assessments of three functional tests via both telerehabilitation and face-to-face approaches, on the same day. The assessment order was randomised and conducted by independent assessors. Outcome measures included functional tests: timed up and go (time), six-minute walk (distance), grip strength (kilograms); system usability scale to rate participant experience with telerehabilitation assessment; and number of technical issues encountered. Validity and inter- and intra-rater reliability of telerehabilitation assessments were examined using limits of agreement, intra-class correlation coefficients (ICC), and paired t-tests. Results The limits of agreement for telerehabilitation assessments were within the clinically acceptable limits for timed up and go and grip strength. Telerehabilitation assessments for all functional tests were strongly associated with face-to-face assessments, with ICCs of between 0.85 and 0.96. Inter- and intra-rater reliability of telerehabilitation assessments for all functional tests were excellent (all ICC > 0.95). The mean (SD) system usability scale score was 85 (15)/100. Some incidences of Internet drop-outs, video freezing and auditory fading occurred. Discussion The use of telehealth for the assessment of functional exercise capacity appears to be valid and reliable in patients with heart failure.

BACKGROUND: Providing flexible models and a variety of exercise options are fundamental to supporting long-term exercise participation for patients with heart failure (HF). The aim of this pilot study was to determine the feasibility and efficacy of aquatic exercise training during a maintenance phase for a clinical heart failure population. METHODS: In this 2 x 2 crossover design trial, individuals who had previously completed HF rehabilitation were randomised into either a land-based or aquatic training program once per week for six weeks, after which time they changed to the alternate exercise training protocol for an additional six weeks. Six-minute walk test (6MWT), grip strength, walk speed, and measures of balance were compared for the two training protocols. RESULTS: Fifty-one participants (43 males, mean age 69.2 yrs) contributed data for the analysis. Both groups maintained function during the follow-up period, however improvements in 6MWT were greater in the land-based training group (95% CI: 0.7, 22.5; p=0.038), by a mean difference of 10.8 metres. No significant difference was observed for other parameters when the two training protocols were compared. CONCLUSION: Attending an aquatic exercise program once per week is feasible for patients with stable HF and may provide a suitable option to maintain functional performance in select patients.

BACKGROUND: The timed up and go test (TUGT) is a short-duration functional test frequently used in rehabilitation settings as a measure of balance and mobility. Reliability and validity for patients with chronic heart failure (CHF) has yet to be determined. This prospective cohort study aimed to determine test-retest reliability of the TUGT in patients with CHF, relationships between the TUGT and other variables, including functional tests, and predictors of the TUGT. METHODS AND RESULTS: This was a secondary analysis of data collected in a multicenter randomized controlled trial of exercise training in recently hospitalized patients with heart failure (EJECTION-HF). The TUGT was conducted twice at baseline to determine reliability. Assessments were compared with 6-minute walk distance (6MWD), 10-m walk test time, and other clinical variables. Intraclass correlation coefficient (ICC) was used to determine test-retest reliability and correlations for relationships with other variables. A multiple regression was used to identify predictors of the TUGT. In 278 participants (mean age 62 years), the TUGT demonstrated excellent within-day test-retest reliability (ICC 0.93). A shorter (better) TUGT time was associated with longer 6MWD (r = -0.81; P < .001) and shorter 10-m walk test time (rs = 0.80; P < .001). Best predictors of the TUGT were 6MWD and age, which accounted for 66% of the variance. CONCLUSIONS: The TUGT appears to be a reliable and valid functional measurement in patients with CHF.

PURPOSE: To examine the effects of telerehabilitation compared with other delivery models for improving physical or functional outcomes in patients with cardiopulmonary diseases. METHODS: A search was completed for English language publications from 1990 to August 2013 across 4 electronic databases and gray literature. Inclusion criteria were: (1) home-based telerehabilitation as a core component; (2) at least 2 exercise sessions; (3) randomized controlled trials; and (4) reporting of physical or functional outcome measures in adult patients with coronary heart disease, chronic heart failure, and chronic respiratory disease. Studies were independently screened by 2 reviewers and graded by a reviewer according to the Downs and Black checklist. A narrative synthesis of the included studies was undertaken. RESULTS: Eleven studies were analyzed. It appears that telerehabilitation is no different to other delivery models for patients with cardiopulmonary diseases, in terms of exercise capacity expressed as distance on the 6-minute walk test and peak oxygen consumption and quality of life. Telerehabilitation appears to have higher adherence rates compared with center-based exercise. There has been similar or no adverse events reported in telerehabilitation compared with center-based exercise. CONCLUSIONS: Although telerehabilitation shows promise in patients with cardiopulmonary diseases, compelling evidence is still limited. There is a need for more detailed, high-quality studies and for studies on the use of video-based telerehabilitation.
