Timed Up and Go Tests in Cardiac Rehabilitation

Comparing the Physiological Responses to the 6-Minute Walk Test, Timed Up and Go Test, and Treadmill Cardiopulmonary Exercise Test

Purpose: To compare physiological responses during a treadmill cardiopulmonary exercise test (CPX), 6-minute walk test (6MWT), and timed up and go test (TUGT) in individuals referred for unexplained breathlessness and symptom limited treadmill exercise testing. Methods: Heart rate (HR), oxygen consumption (V̇O2), carbon dioxide production (V̇CO2), respiratory exchange ratio (RER), minute ventilation (V̇E), systolic blood pressure (SBP), and rating of perceived exertion (RPE) were recorded throughout each test. Results: Each test demonstrated a significant increase (p < 0.01) in the cardiopulmonary (V̇O2, V̇CO2 and V̇E, RPE, SBP, and HR) and perceptual (RPE) responses from rest to end exercise. The increase in cardiopulmonary and perceptual responses was greatest for the CPX with significantly smaller responses demonstrated during the 6MWT (p < 0.01) and even smaller responses for the TUGT (p < 0.01 vs CPX and 6MWT). Conclusion: Not surprisingly, the treadmill CPX results is the greatest physiological response in our group. Despite being of short duration, the TUGT results in an increased physiological response.

Whole body resistance training on functional outcomes of patients with Stage 4 or 5 chronic kidney disease: A systematic review

Chronic kidney disease (CKD) causes skeletal muscle wasting, resulting in reduced function and inability to live independently. This systematic review critically appraised the scientific literature regarding the effects of full-body resistance training on clinically-relevant functional capacity measures in CKD. The study population included studies of people with Stage 4 or 5 CKD and a mean age of 40+ years old. Eight databases were searched for eligible studies: Pubmed, Embase, Cochrane, CINAHL, Scopus, Web of Science, MEDLINE, and AGELINE. MeSH terms and keyword combinations were used for screening following the PRISMA conduct. Inclusion criteria were based on PICO principles and no date of publication filter was applied. The intervention was training 2 days/week of structured resistance exercises using major upper and lower muscle groups. Minimum intervention period was 7 weeks. Comparison groups maintained their habitual activity without structured exercise training. Outcome measures of interest were: 6-min walk test, grip strength, timed up-and-go test, and sit-to-stand. Eight randomized controlled trials and one nonequivalent comparison-group study fulfilled the inclusion criteria and underwent data extraction. All studies were of hemodialysis patients. The evidence indicates that full-body resistance exercise significantly improved grip strength, timed up and go and sit to stand tests; metrics associated with enhanced quality and quantity of life.

A comparative analysis of open heart surgery and minimally invasive cardiac surgery in exercise-based cardiac rehabilitation

BACKGROUND

Historically, the majority of patients admitted to inpatient exercise-based cardiac rehabilitation (EBCR) have undergone open heart surgery (OHS). However, with advances in minimally invasive cardiac surgery (MICS), these patient groups are also increasingly referred for inpatient EBCR. Herein, we aimed to compare the progress of these groups during rehabilitation.

METHODS

In this prospective, nonrandomized study, 403 inpatient EBCR patients were recruited from December 2022 until September 2023 and stratified into two groups: OHS, and MICS. Participants completed a 3-4-week certified EBCR program. The primary endpoint was defined as a change in the 6-minute walk test (6MWT). Moreover, a comprehensive panel of quality-of-life (QoL) assessments were performed at admission and discharge.

RESULTS

At baseline, patients with OHS were older (66 years [IQR 59 - 72]), more often male (83%), and underwent emergency/urgent procedures more often (20%) than patients with MICS. Furthermore, patients with MICS showed a better 6MWT at admission (426 meters [IQR 336 - 483]) compared to patients with OHS (381 meters [IQR 299 - 453]). While all patients were able to increase the distance in the 6MWT, regression analyses in fully adjusted models showed no difference in improvements between the two groups (β -5, 95% CI, -26 - 14, p = 0.58). Moreover, during EBCR, we observed significant improvements in all QoL measures in all groups.

CONCLUSIONS

In this study, improvements in fitness, as assessed by the 6WMT were observed in all groups. Furthermore, multiple QoL measures improved equally across all groups. These encouraging results emphasize the importance of EBCR.

Effects of Cardiac Rehabilitation on Physical Fitness, Physical Function, and Self-reported Outcomes in Patients ≥80 yr: A RANDOMIZED CONTROLLED TRIAL

PURPOSE

The beneficial effects of exercise-based cardiac rehabilitation (CR) after an acute coronary syndrome (ACS) are well known, but patients ≥80 yr have been less studied. The aim was to evaluate the effects of CR on patients with ACS ≥80 yr on peak cardiorespiratory fitness (CRF), physical function, and patient-reported outcome measures (PROMs) compared with a control group.

METHODS

A total of 26 patients with ACS, median age 82 (81, 84) yr, were randomized to hospital-based CR combined with a home-based exercise program (CR group) or to a control group (C) for 4 mo. Outcomes were assessed at baseline and 4 mo and included the peak CRF (primary outcome), 6-min walk test (6MWT), muscle endurance, Timed Up and Go (TUG), Short Physical Performance Battery (SPPB), one-leg stand test, and PROMs.

RESULTS

There were no significant differences between the groups in peak CRF. The CR group improved significantly in terms of the 6MWT ( P = .04), isotonic muscle endurance ( P < .001), one-leg stand test ( P = .001), SPPB total score ( P =.03), Activities-specific Balance Confidence ( P =.01), and anxiety ( P =.03), as compared with C. There were no significant intergroup differences in the TUG, the self-reported health question or depression.

CONCLUSIONS

Patients with ACS ≥80 yr improved in walking distance, muscle endurance, physical function, and PROMs, but not in peak CRF, by participating in a CR program. These results suggest an increased referral to CR for this growing group of patients to enable preserved mobility and independence in daily living, but this needs to be confirmed in larger studies.

Virtual reality exercises at home for post COVID-19 condition: a feasibility study

BACKGROUND

Between 30-76% of COVID-19 patients have persistent physical and mental symptoms, sometimes up to 9 months after acute COVID-19. Current rehabilitation is mostly focused on the physical symptoms, while experts have agreed on the need for a biopsychosocial approach. A novel approach such as Virtual Reality (VR) rehabilitation at home might benefit patients and therapists, especially considering the expected rush of patients with post-COVID-19-condition needing rehabilitation.

OBJECTIVE

To investigate the feasibility of self-administered VR exercises at home for post COVID-19-condition.

METHODS

This is a single-arm feasibility study in an outpatient care setting. Patients who needed physiotherapy because of post COVID-19 condition were included as determined by the treating physiotherapist. Participants performed VR physical exercises at home for a period of 6 weeks and were allowed to perform VR mental exercise apps available at the VR platform to reduce stress and anxiety and promote cognitive functioning. Main outcomes were related to feasibility, i.e. duration and frequency of VR use, safety i.e. adverse events, patient satisfaction, and reasons to withdraw. Physical performance, daily activities, cognitive functioning, anxiety and depression, and quality of life were measured before and after.

RESULTS

Forty-eight patients were included. One patient did not start VR and seven patients (15%) withdrew, mostly due to dizziness. Almost 70% of participants reported any adverse event during VR exercising. However, only 25% recalled these events at the end of the intervention period. The majority of patients described VR as having a positive influence on their recovery and the global satisfaction score was 67%. Average VR use was 30 minutes per session 3-4 times a week for 3-6 weeks. Overall use of VR applications was almost equally distributed over the three sets of VR exercises (physical, relaxing, cognitive). However, use frequency of physical exercises seemed to decrease over time, whereas use of cognitive and relaxation exercises remained stable. Physical performance and quality of life outcomes were significantly improved after six weeks.

CONCLUSIONS

VR physical exercises at home is feasible and safe with good acceptance in a significant percentage of patients with post COVID-19 condition.

Home-based and remote functional exercise testing in cardiac conditions, during the covid-19 pandemic and beyond: a systematic review

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.

Intra- and Inter-Rater Reproducibility of the Face-to-Face and Tele-Assessment of Timed-up and Go and 5-Times Sit-to-Stand Tests in Patients with Chronic Obstructive Pulmonary Disease

Timed-Up and Go (TUG) and 5-Times Sit-to-Stand (5STS) are frequently used in clinical practice for patients with chronic obstructive pulmonary disease (COPD). The aim of the study was to investigate the intra- and inter-rater reproducibility of the TUG and 5STS as both face-to-face and tele-assessment tests in patients with COPD. Forty-four patients with diagnosed COPD were included. Evaluations were carried out face-to-face and tele-assessment (synchronized and asynchronized). Inter-reliability between face-to-face and tele-assessment was excellent for TUG (ICC = 0.977) and 5STS (ICC = 0.970). Inter-reliability between two tele-raters was also excellent for TUG (ICC = 0.995) with the SEM = 0.04, SEM95% = 0.08, and SDC95% = 0.10 s, and 5STS (ICC = 0.990) with the SEM = 0.06, SEM95% = 0.12, and SDC95% = 0.18 s. Intra-rater reliability of the tele-assessment (synchronized) was excellent for TUG (ICC = 0.976) and 5STS (ICC = 0.964). The SEM, SEM95%, and SDC95% values were computed as 0.08, 0.16, and 0.22 s for TUG, and 0.11, 0.22, and 0.31 s for 5STS, respectively. The TUG and 5STS tests are reproducible tele-assessment measures in patients with COPD with excellent intra- and inter-rater reproducibility. The authors recommend these tests as practical assessment tools in patients with COPD at home for tele-health interventions. The reported SEM, SEM95%, and SDC95% values can be used as a minimum change that needs to be observed to be confident that the observed change is real and not, potentially, a product of measurement error.

The Association Between Physical Performance and Health-Related Quality of Life Based on the EuroQol 5-Dimensional Questionnaire in Patients With Chagas Disease

OBJECTIVES

Chagas disease (CD) is a chronic disease to millions worldwide, and many patients develop heart disease. In addition, they are part of an aging population. These characteristics can be associated with a reduction in physical performance and health-related quality of life (HRQoL). This study evaluated HRQoL, and the relationship between physical performance and HRQoL in patients with chronic CD.

METHODS

We used the 3-level version of EuroQol 5-dimensional questionnaire (EQ-5D-3L), with the visual analog scale (VAS). Physical performance was measured with 30-s chair-stand test (30sCST) and timed up and go test (TUGT).

RESULTS

Sixty-three patients were evaluated. The majority were women (68.2%) aged 67.7 ± 9.7 years. Overall EQ-5D-3L utility index was 0.65 ± 0.28, and VAS score was 68.4 ± 25.1. Most patients with intermediate and high performance in 30sCST referred no problems in the domains "mobility," "usual activities," and "pain/feeling ill" (P < .001, P = .01, and P = .025, respectively). In a similar way, most patients with intermediate and high performance in TUGT referred no problems in "mobility" (P < .0001) and "usual activities" (P = .001). Higher performance in both tests was associated with higher overall EQ-5D-3L utility and VAS scores. HRQoL measured by EQ-5D-3L was associated with physical status in a cohort of patients with chronic CD. The results underscore the contribution of physical performance, measured by 2 inexpensive and safe physical tests, to HRQoL in these patients.

CONCLUSION

Strategies aiming the improvement of HRQoL in patients with CD may focus on mobility skills and force. Future studies evaluating interventions in physical performance should be a priority in these patients.

Utility of Timed Up and Go in Outpatient Cardiology Clinics

PURPOSE

The aim of the study was to examine if the Timed Up and Go (TUG) Test would be a feasible, reproducible, and valid measure in patients post-coronary artery bypass grafting (CABG).

DESIGN

Cross-sectional study, controls and patients post-CABG, outpatient clinic.

METHODS

Participants performed the TUG Test and the 6-Minute Walking Distance (6MWD) Test. Reliability was measured within observer on two occasions.

FINDINGS

Patients and controls were similar in age. The patients had greater TUG mean (SD) of 14.4 seconds (4.9 seconds) and lower 6MWD of 358 m (76 m) compared with TUG of 8.2 seconds (2.7 seconds) and 6MWD of 487 m (56 m) in controls. In patients, intraclass correlation for the TUG was .98 (95% CI [.96, .98]) between the measurements. In patients, there was a high correlation between the TUG Test and the 6MWD Test, r = -.70, p < .001.

CONCLUSION

The TUG Test demonstrated to be a feasible, reproducible, and valid measure in patients post-CABG.

CLINICAL RELEVANCE

The TUG Test could serve as a screening tool for physical performance in clinics.

Test-retest reliability and validity of the timed up and go test and 30-second sit to stand test in patients with pulmonary hypertension

BACKGROUND

Timed up and go (TUG) and sit to stand (STS) tests that required less space and easier to be performed in respiratory and cardiac diseases for assessing functionality. Aim was to test the reliability of TUG and 30-second STS (30STS) tests and determine the validity of TUG and 30STS tests in patients with Pulmonary Hypertension (PH).

METHODS

Thirty-eight patients with diagnosed PH were included. We collected TUG, 30STS, quadriceps muscle strength, physical activity level, and 6MWT. Intra-class correlation coefficient (ICC) was used to determine test-retest reliability and correlations with quadriceps muscle strength, physical activity level and 6MWT for validity of the TUG and 30STS tests.

RESULTS

The TUG and 30STS tests were associated with age, functional class, muscle strength, physical activity and functional exercise capacity in patients with PAH (p < 0.05). 6MWT was associated with age, functional class, muscle strength, physical activity and functional exercise capacity (p < 0.05). ICC (95%) for TUG test and 30STS were 0.96 (0.93-0.98) and 0.95 (0.90-0.97), respectively.

CONCLUSIONS

The TUG and 30STS tests were reliable and valid tests for measuring physical performance in PH. This study supports using the TUG and 30STS tests as practical assessment tools in patients with PH.

Real-life feasibility of home-based pulmonary rehabilitation in chemotherapy-treated patients with thoracic cancers: a pilot study

Background

Patients with advanced lung cancer (LC) or malignant pleural mesothelioma (MPM) exhibit limitation of exercise capacities and alteration of quality of life (QoL) induced by cancer and its treatment. Few studies assessed pulmonary rehabilitation (PR) in these chemotherapy-treated patients, and none evaluated a home-based PR program.

Methods

In this prospective uncontrolled observational pilot study, patients treated by chemotherapy for LC or MPM were screened for a home-based PR program combining exercise training with global cares including therapeutic education and psychosocial management. Feasibility and safety were evaluated by attendance and adherence to PR program. Various exercise tolerance tests, including 6-min walk test (6MWT) and 6-min stepper test (6MST), were performed before and after PR associated with, QoL and psychological assessment (VSRQ and HAD, respectively).

Results

243 patients were considered eligible but only 71 (60.6 ± 8.8 years) started a PR and 47 completed the program. Refusals to participate were mostly related to lack of motivation whereas withdrawals to PR were related to cancer-related medical issues. No adverse event related to PR was observed. Baseline 6MWT distance was associated with performance status (r = − 0.45, p = 0.001) and mMRC dyspnea scale (r = − 0.49, p < 0.001) but not with lung cancer stage. Post-PR reassessment showed 6MWT stability and 6MST improvement in patients who completed the program. Daily physical activity (p = 0.007) and anxiety (p = 0.02) scores were significantly improved.

Conclusions

Home-based PR was feasible and safe in patients with advanced LC or MPM. Exercise capacities stability in patients who completed the PR program suggests that PR might be beneficial. Further studies are warranted to confirm and to improve the potential value of PR in these patients.

Correlates of Exercise Self-efficacy in a Randomized Trial of Mind-Body Exercise in Patients With Chronic Heart Failure

PURPOSE

Exercise self-efficacy is one of the strongest predictors of physical activity behavior. Prior literature suggests that tai chi, a mind-body exercise, may increase self-efficacy; however, this is not extensively studied. Little is known about the factors associated with development of exercise self-efficacy in a population with heart failure.

METHODS

We utilized data from a randomized controlled trial of 12 weeks of group tai chi classes versus education in patients with chronic heart failure (n = 100). Multivariable linear regression was used to explore possible correlates of change in exercise self-efficacy in the entire sample and in the subgroup who received tai chi (n = 50). Covariates included baseline quality of life, social support, functional parameters, physical activity, serum biomarkers, sociodemographics, and clinical heart failure parameters.

RESULTS

Baseline 6-minute walk (β=-0.0003, SE = 0.0001, P = .02) and fatigue score (β= 0.03, SE = 0.01, P = .004) were significantly associated with change in self-efficacy, with those in the lowest tertile for 6-minute walk and higher tertiles for fatigue score experiencing the greatest change. Intervention group assignment was highly significant, with self-efficacy significantly improved in the tai chi group compared to the education control over 12 weeks (β= 0.39, SE = 0.11, P < .001). In the tai chi group alone, lower baseline oxygen uptake (β=-0.05, SE = 0.01, P = .001), decreased mood (β=-0.01, SE = 0.003, P = .004), and higher catecholamine level (epinephrine β= 0.003, SE = 0.001, P = .005) were significantly associated with improvements in self-efficacy.

CONCLUSIONS

In this exploratory analysis, our initial findings support the concept that interventions like tai chi may be beneficial in improving exercise self-efficacy, especially in patients with heart failure who are deconditioned, with lower functional status and mood.

Assessing functional exercise capacity using telehealth: Is it valid and reliable in patients with chronic heart failure?

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.

Long-term evaluation of home-based pulmonary rehabilitation in patients with COPD

Introduction

Personalized, global pulmonary rehabilitation (PR) management of patients with COPD is effective, regardless of the place in which this rehabilitation is provided. The objective of this retrospective observational study was to study the long-term outcome of exercise capacity and quality of life during management of patients with COPD treated by home-based PR.

Methods

Home-based PR was administered to 211 patients with COPD (mean age, 62.3±11.1 years; mean forced expiratory volume in 1 second, 41.5%±17.7%). Home-based PR was chosen because of the distance of the patient’s home from the PR center and the patient’s preference. Each patient was individually managed by a team member once a week for 8 weeks with unsupervised continuation of physical exercises on the other days of the week according to an individual action plan. Exercise conditioning, therapeutic patient education, and self-management were included in the PR program. The home assessment comprised evaluation of the patient’s exercise capacity by a 6-minute stepper test, Timed Up and Go test, ten times sit-to-stand test, Hospital Anxiety and Depression score, and quality of life (Visual Simplified Respiratory Questionnaire, VQ11, Maugeri Respiratory Failure 28).

Results

No incidents or accidents were observed during the course of home-based PR. The 6-minute stepper test was significantly improved after completion of the program, at 6 months and 12 months, whereas the Timed Up and Go and ten times sit-to-stand test were improved after PR and at 6 months but not at 12 months. Hospital Anxiety and Depression and quality of life scores improved after PR, and this improvement persisted at 6 months and 12 months.

Conclusion

Home-based PR for unselected patients with COPD is effective in the short term, and this effectiveness is maintained in the medium term (6 months) and long term (12 months). Home-based PR is an alternative to outpatient management provided all activities, such as exercise conditioning, therapeutic education, and self-management are performed.

Development of the Internet-Enabled System for Exercise Telerehabilitation and Cardiovascular Training

OBJECTIVE

Sustained exercise training could significantly improve patient rehabilitation and management of noncommunicable diseases in the community. This study aimed to develop a universal telecare system for delivery of exercise rehabilitation and cardiovascular training services at home.

MATERIALS AND METHODS

An innovative bilateral leg training device was equipped with an electronic system for the ongoing measurement of training activities with the device. A single-item parameter reflecting the intensity of training was monitored using several modern telecommunication technologies. According to the application protocol, eight volunteers first tried the device for 30-60 min to determine their personal training capacity. Then, they were provided with equipment to use at home for 4 weeks. Adherence to daily training was assessed by the number of training days per week, training intensity, and duration of training sessions.

RESULTS

The system provided reliable recording of training activities with the device using (1) long-term data logging without an ongoing connection to the computer, (2) wireless monitoring and recording of training activities on a stand-alone computer, and (3) a secure cloud-based monitoring over the Internet connection using electronic devices, including smartphones. Overall analysis of recordings and phone feedbacks to participants took only approximately 5 h for the duration of study.

CONCLUSIONS

This study, although of a pilot nature, described the comprehensive exercise telerehabilitation system integrating mobile training equipment with personalized training protocols and remote monitoring. A single-item electronic parameter of the system usage facilitated time-effective data management. Wireless connection allowed various locations of device application and several monitoring arrangements ranging from real-time monitoring to long-term recording of exercise activities. A cloud-based software platform enabled management of multiple users at distance. Implementation of this model may facilitate both accessibility and availability of personalized exercise telerehabilitation services. Further studies would validate it in the clinical and healthcare environment.

Tasmanian Aborigines step up to health: evaluation of a cardiopulmonary rehabilitation and secondary prevention program

BACKGROUND

Although the burden of cardiopulmonary diseases in the Aboriginal community is high, utilisation of rehabilitation services has been poor. We evaluated the uptake and effectiveness of a cardiovascular and pulmonary rehabilitation program specifically designed and provided for the Aboriginal community, by the Tasmanian Aboriginal Centre, for people with diagnosed chronic heart or respiratory disease and those at high risk of developing such conditions.

METHODS

Participants had established chronic obstructive pulmonary disease, ischaemic heart disease or chronic heart failure or were at high risk of developing such diseases because of multiple risk factors. Rehabilitation programs (n = 13) comprised two exercise and one education session per week over eight weeks. Data, collected at baseline and on completion, included health status, risk factors, attendance, anthropometric measurements, physical capacity and quality of life. Data from participants who attended at least one program session were analysed. Qualitative written feedback from participants and staff was analysed thematically.

RESULTS

Of 92 participants (39% with an established disease diagnosis), 72 provided follow-up data. Participants lost weight, and waist circumference decreased (mean -3.6 cm, 95% confidence interval (CI)-2.5 to -4.7). There were clinically significant improvements in six-minute walk distance (mean 55.7 m, 95% CI 37.8 to 73.7) and incremental shuttle walk (mean 106.2 m, 95% CI 79.1 to 133.2). There were clinically significant improvements in generic quality of life domains, dyspnoea and fatigue. Generally, the improvements in participants with established cardiac or respiratory diseases did not differ from that in people with risk factors. Analysis of qualitative data identified three factors that facilitated participation: support from peers and health workers, provision of transport and the program structure. Participants' awareness of improvements in their health contributed to ongoing participation and positive health outcomes, and participants would recommend the program to family and friends.

CONCLUSION

A cardiopulmonary program, which included exercise and education and met national guidelines, was designed and delivered specifically for the Aboriginal community. It increased participation in rehabilitation by Aborigines with, or at high risk of, established disease and led to positive changes in health behaviours, functional exercise capacity and health related quality of life.
