What Is the "Home" in Home-Based Exercise? The Need to Define Independent Exercise for Survivors of Cancer

Efficacy of aerobic and resistance exercises on cancer pain: A meta-analysis of randomised controlled trials

Purpose

To evaluate effects of aerobic and resistance exercises for cancer-related pain in adults with and surviving cancer. Secondary objectives were to a) evaluate the effect of exercise on fatigue, psychological function, physical function, b) assess fidelity to exercise.

Design

A systematic search of MEDLINE, EMBASE, AMED, CINAHL and Cochrane Central Register of Controlled Trials was conducted to identify randomised controlled trials (RCTs) comparing aerobic and/or resistance exercise to control groups. The primary endpoint were changes in cancer-related pain intensity from baseline to post intervention. Meta-regression analysis evaluated predictors for heterogeneity between study findings. Tolerability was defined as reporting of exercise-induced adverse events while fidelity evaluated by reported intervention dropout.

Results

Twenty-three RCTs including 1954 patients (age 58 ± 8.5 years; 78 % women); 1087 (56 %) and 867 (44 %) allocated to aerobic/resistance exercise therapy and control group, respectively. Exercise therapy was associated with small to moderate decreases in cancer-related pain compared to controls (SMD = 0.38, 95 % CI: 0.17, 0.58). Although there was significant heterogeneity between individual and pooled study effects (Q = 205.25, p < 0.0001), there was no publication bias. Meta-regression including supervision, age, duration and exercise type as moderators showed no significant differences in reported outcomes. Analysis of secondary outcomes revealed a moderate effect for improvements in physical function, fatigue and psychological symptoms.

Conclusions

Aerobic and resistance exercises are tolerable and effective adjunct therapies to reduce cancer-related pain while also improving physical function, fatigue and mood. Future RCTs of dose, frequency, compliance and exercise type in specific cancer settings are required.

Effectiveness of home-based interventions in improving loneliness and social connectedness among older adults: a systematic review and meta-analysis

OBJECTIVES

To evaluate the effectiveness of home-based interventions in improving loneliness and social connectedness (primary outcomes), and depressive symptoms (secondary outcome) among older adults.

METHODS

Eight electronic databases were searched from inception dates to February 2022. Meta-analyses were conducted using a random-effect model. Heterogeneity was assessed using I2 statistics and Cochran's Q chi-squared test. The Cochrane risk of bias tool and the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) was used to appraise the included studies.

RESULTS

Fourteen randomized controlled trials were included. Home-based interventions were found to significantly increase older adults' social connectedness (social support and social engagement) and reduce their loneliness and depressive symptoms. Subgroup analyses suggested that interventions which lasted more than three months and were delivered using mixed platforms were more favorable. Both professional-led and volunteer-led interventions showed favorable results.

CONCLUSIONS

Future studies could be conducted in varied geographical regions and consider carrying out follow-up assessments. Home-based interventions could be improved by being more than months, delivered by mixed personnel, and using mixed platforms. Considering the low-quality rating by the GRADE approach, future research is needed to confirm current findings.

An online home-based exercise program improves autonomic dysfunction in breast cancer survivors

Introduction: Exercise interventions for breast cancer survivors have proved their potential to improve clinical, physical, and psychosocial outcomes. However, limited studies have explored exercise effects on autonomic dysfunction and the measurement of exercise tolerance and progression through daily heart rate variability (HRV). Purpose: To analyze the effects of a 16-wk exercise intervention on the autonomic modulation of breast cancer survivors, as well as to examine the evolution of daily measured HRV and its interaction with exercise sessions in this population. Methods: A total of 29 patients who had undergone chemotherapy and radiotherapy were randomly assigned to the exercise group or to the control group. The exercise intervention was delivered remotely through online meetings and consisted of supervised training resistance and cardiovascular exercise 3 times per week. During the intervention all patients measured their HRV daily obtaining the napierian logarithm of the root mean square of successive differences between normal heartbeats (lnrMSSD) and the napierian logarithm of the standard deviation of the interbeat interval of normal sinus beats (lnSDNN) values at four moments: day 0 (the morning of the training sessions), 24, 48, and 72 h after exercise. Results: The results revealed a significant interaction between group and months during the intervention period for lnrMSSD and lnSDNN (p < 0.001). Additionally, there were significant differences in lnSDNN recovery time between months (p < 0.05), while differences in lnrMSSD become apparent only 24 h after exercise (p = 0.019). The control group experienced a significant decrease in both variables monthly (p < 0.05) while exercise group experienced a significant increment (p < 0.05). Conclusion: HRV is daily affected by exercise training sessions in cancer patients. Although results strongly support the role of exercise as a post-chemotherapy and radiotherapy rehabilitation strategy for breast cancer survivors to improve autonomic imbalance, further research is necessary to validate these initial findings.

Generic Health Utility Measures in Exercise Oncology: A Scoping Review and Future Directions

Despite the evidence that exercise is effective at mitigating common side effects in adults with cancer, it is rarely part of usual cancer care. One reason for this is the lack of economic evidence supporting the benefit of exercise. Economic evaluations often rely on the use of generic utility measures to assess cost effectiveness. This review identifies and synthesizes the literature on the use of generic utility measures used to evaluate exercise interventions for adults with cancer. A systematic search of the literature from January 2000 to February 2023 was conducted using four databases (Medline, EMBASE, CINAHL, Academic Search Complete). Exercise studies involving adults with any type of cancer that used a generic utility measure were eligible for inclusion. Of the 2780 citations retrieved, 10 articles were included in this review. Seven articles included economic evaluations, with varying results. Four studies reported on cost-effectiveness; however, detailed effectiveness data derived from the generic utility measure were often not reported. Generic utility measures help to compare baseline values of and changes in health utility weights across studies and to general population norms; however, to date, they are underutilized in exercise oncology studies. Consideration should be given to the identified research evidence, population, and methodological gaps.

Home-based, supervised, and mixed exercise intervention on functional capacity and quality of life of colorectal cancer patients: a meta-analysis

This systematic review and meta-analysis of randomized controlled trials tested the effects of home-based, supervised, or mixed exercise interventions on the functional capacity (FC) and quality of life (QoL) in colorectal cancer patients. A literature search was performed using the PubMed, Embase, Cochrane, and Medline databases. Two reviewers screened the literature through March 10, 2021 for studies related to exercise and colorectal cancer. Of the 1161 screened studies in the initial search, 13 studies met the eligibility criteria (home-based = 6 studies; supervised or mixed = 7 studies). Overall, 706 patients were enrolled in the trials, and 372 patients were submitted to home-based, supervised, or mixed exercise intervention. The overall results from the main meta-analysis showed a significant effect regarding supervised or mixed intervention (6 studies; p = 0.002; I² = 43%; PI 0.41–1.39); however, no significant effect was observed for home-based intervention (5 studies; p = 0.05; I² = 25%; PI − 0.34–0.76). A sensitivity analysis based on studies with intervention adherence ≥ 80% (home-based = 3 studies; supervised or mixed = 4 studies) revealed that home-based intervention or intervention entirely supervised or with some level of supervision (mixed) are effective in improving the QoL and FC of CRC patients. In summary, this meta-analysis verified that supervised and home-based exercise can modify QoL and FC when intervention adherence ≥ 80%. Regardless of the supervision characteristics, future RCTs are strongly encouraged to provide a detailed description of the exercise variables in physical interventions for CRC prescription. This perspective will allow a refined exercise prescription for patients with CRC, mainly according to their clinical status.

Is It Really Home-Based? A Commentary on the Necessity for Accurate Definitions across Exercise and Physical Activity Programmes

Background: There is wide discrepancy in how published research defines and reports home-based exercise programmes. Studies consisting of fundamentally different designs have been labelled as home-based, making searching for relevant literature challenging and time consuming. This issue has been further highlighted by an increased demand for these programmes following the COVID-19 pandemic and associated government-imposed lockdowns. Purpose: To examine what specifically constitutes home-based exercise by: (1) developing definitions for a range of terms used when reporting exercise and physical activity programmes and (2) providing examples to contextualise these definitions for use when reporting exercise and physical activity programmes. Methods: A literature search was undertaken to identify previous attempts to define home-based exercise programmes. A working document, including initial definitions and examples were developed, which were then discussed between six experts for further refinement. Results: We generated definitions for universal key terms within three domains (and subdomains) of programme design: location (home-based, community/centre-based, or clinical setting), prescription (structured or unstructured) and delivery (supervised, facilitated, or unsupervised). Examples for possible combinations of design terms were produced. Conclusions: Definitions will provide consistency when using reporting tools and the intention is to discuss the issues presented as part of a Delphi study. This is of paramount importance due to the predicted increase in emerging research regarding home-based exercise.

Physical exercise and COVID-19 pandemic in PubMed: Two months of dynamics and one year of original scientific production

Our aim was to conduct a narrative review about physical exercise and Corona Virus Disease 2019 (COVID-19). A literature search was completed crossing the keywords “COVID-19” and “physical exercise”, for a narrative review, and physical activity (PA), physical exercise, physical training, sport, physical fitness, for a systematic review; search strategy (Randomized Controlled Trial, in the last 1 year, English). The first search date was closed on 04/26/2020 and 06/26/2020. This strategy was chosen to assess the dynamics of scientific information production for the pandemic. In two months, an increase of 76%, from 12 (19.4%) to 50 (80.64%) COVID-19 articles (n = 62, 100%) was found. The main types of articles published were editorial articles (16.13%, n = 10 of 62 articles) and commentary (9.68%, n = 6 of 62 articles). The most frequent country of origin of the scientific production was the United States (12.90%, n = 8 of 62 articles), the United Kingdom (12.90%, n = 8 of 62 articles), and Brazil (11.29%, n = 7 of 62 articles). However, in 2020, there were only 2 relevant randomized controlled trials on the COVID-19 topic in the context of physical exercise. Scientific information production shows the concern of the PA science community to bring a solution to the increase in physical inactivity generated by the COVID-19 pandemic. Our findings show the dynamics of scientific production on the COVID-19, in a situation so unique such as a pandemic, denotes that the practice of PA is essential to improve and/or maintain physical and mental health.

The Development Strategy of Home-Based Exercise in China Based on the SWOT-AHP Model

In view of the increasing importance of sports to people and the impact of COVID-19 on people’s lives, home-based exercise has become a popular choice for people to keep fit due to its unique advantages and its popularity is expected to keep growing in the future. Therefore, it is necessary to determine the development direction of home-based exercise and put in the corresponding efforts. However, there is currently a lack of research on all aspects of home-based exercise. The purpose of this research was to investigate the effective sustainable development strategy of home-based exercise in China through a SWOT (Strengths, Weaknesses, Opportunities and Threats) and AHP (Analytic Hierarchy Process) hybrid model. Thirteen factors corresponding to the SWOT analysis were identified through a literature review and expert opinions. The results show that in China the advantages and potential outweigh the weaknesses and threats of home-based exercise. Home-based exercise should grasp the external development opportunities and choose the SO development strategic type that combines internal strengths and external opportunities. As the core for the development of home-based exercise, this strategy should be given priority. To sum up, home-based exercise is believed to have a bright future.

"This is my home-based exercise": exploring environmental influences on home-based exercise participation in oncology

PURPOSE

Home-based exercise interventions offer many health benefits; however, the environments that constitute home-based exercise are not well-understood. The purpose of this study was to explore what constitutes the "home" for cancer survivors engaging in home-based exercise and identify factors of the environment that may impact exercise participation.

METHODS

We conducted a qualitative exploratory study of cancer survivors receiving a home-based exercise prescription to manage their cancer-related impairments. Semi-structured interviews included photo elicitation to actively involve participants in the interview process and provide opportunities to visually "observe" environments utilized for home-based exercise.

RESULTS

Sixteen participants were interviewed (n = 11 women, median age = 53.5, range = 26-74 years) and three themes emerged: (1) reasons for participating in a home-based exercise program; (2) physical environmental influences and preferences; and (3) social environmental influences and preferences. The ability to self-manage exercise and accommodate competing demands, having access to exercise facilities, feeling comfortable exercising without qualified supervision, and a desire for autonomy were reasons home-based exercise programs were preferred. Participants reported that the physical environment influenced their experience with home-based exercise and sub-themes related to a dynamic environment, indoor and outdoor characteristics, and aesthetics were identified. The social environment, with sub-themes associated with the presence of people, social climate, exercise modeling, connection, and exercise support, also related to exercise behavior.

CONCLUSION

The findings highlight the influence of the physical and social environment on exercise prescription engagement. They further indicate the need for exercise professionals to consider the environment for exercise when delivering home-based exercise interventions.

Feasibility and Effectiveness of Implementing a Novel Exercise and Self-Management Programme during Chemotherapy for Women with Breast Cancer: A Pilot Randomized Controlled Trial

Purpose: The aim of this study was to determine the feasibility and effectiveness of implementing a novel exercise and self-management programme for women with breast cancer during chemotherapy. Method: The study used a pilot implementation design with a randomized controlled trial methodology. The 26 participants were adult breast cancer survivors (Stages 1-3) undergoing chemotherapy treatment. The intervention group received eight sessions of individualized, supervised, moderate-intensity aerobic exercise, paired with self-management modules in the cancer institution; the comparison group received usual care. The primary outcome assessed was feasibility of the implementation strategies. The secondary outcomes - level of physical activity, quality of life, exercise knowledge and behaviour, and perception of health status - were assessed at baseline, post-intervention, and 2- and 4-month follow-up. Descriptive statistics were used to measure the feasibility outcomes (recruitment rate, retention rate, adherence rate, and number of adverse events). A repeated-measures analysis of covariance was used to compare the secondary outcomes between the intervention and control groups at various time points. Results: The recruitment rate was 96%, retention rate was 100%, and adherence rate was 89%. No adverse events occurred. A between-groups difference was found for levels of physical activity post-intervention (mean difference = 25.38 points on the Godin Leisure-Time Exercise Questionnaire; 95% CI: 9.34, 41.42). There were no other significant findings. Conclusions: The implementation strategy was feasible. This programme has the potential to improve women's physical activity level during chemotherapy. Further research is needed to determine strategies to help survivors maintain these results over the long term.

Variability and limitations in home-based exercise program descriptions in oncology: a scoping review

BACKGROUND

The literature reflects considerable heterogeneity in what constitutes home-based exercise interventions. The variability for where and what "home-based" exercise can represent challenges interpretation of findings and appropriate advocacy, referral, or development of these models of care. Therefore, the objective of this review was to provide a comprehensive summary of how home-based exercise is defined and reported in the literature and summarize the range of supportive elements utilized in home-based exercise trials.

METHODS

We followed methodology for scoping reviews. Relevant research databases were searched from inception to March 2019. Two reviewers independently screened articles to determine eligibility and extracted terminology used to describe home-based exercise and intervention details for intervention delivery.

RESULTS

Of the 9432 records identified, 229 articles met inclusion criteria. Across the literature, exercise interventions were described as home-based if they were completed at-home, outdoors in the neighbourhood, and in community facilities; or in self-selected environments; or if they were unsupervised. Supportive elements for home-based models ranged with respect to the amount of supervision and resources utilized, including the provision of print materials, exercise equipment, telephone support, home visits, and technology.

CONCLUSIONS

This review provides a comprehensive summary of strategies previously utilized to deliver home-based exercise interventions in oncology, along with the various definitions of the home-based environment for exercise reported by researchers. Specific recommendations to improve the prescription and reporting of home-based exercise interventions are provided in order to facilitate the delivery, evaluation, and translation of findings into clinical practice.

Preferences for mHealth physical activity interventions during chemotherapy for breast cancer: a qualitative evaluation

PURPOSE

Physical activity has been shown to decline over the course of chemotherapy in breast cancer survivors; yet it may reduce treatment-related side effects and emerging evidence indicates it may improve disease outcomes. Mobile health (mHealth) interventions may be an effective, scalable strategy to increase physical activity during treatment. However, little is known about breast cancer patients' interests and preferences for these interventions. It is important to understand patients' interests and preferences prior to development of mHealth physical activity interventions to increase their relevance and efficacy.

METHODS

Breast cancer survivors (n = 30) participated in a semi-structured phone interview and were asked about barriers and facilitators to physical activity during chemotherapy as well as their preferences on a range of potential mHealth intervention features. Transcribed interviews were coded and key themes were analyzed using an iterative, inductive approach.

RESULTS

Five key themes were extracted from the interviews: (1) need for education about physical activity during chemotherapy; (2) treatment side effects inhibit physical activity; (3) a structured, home-based, tech-supported program with in-person elements is most feasible; (4) need for a personalized, highly tailored intervention; and (5) importance of social support from other breast cancer survivors, friends, and family.

CONCLUSIONS

Breast cancer survivors are interested in mHealth physical activity interventions during chemotherapy, but preferences for intervention content and delivery varied. Future work should engage patients and survivors in intervention development and testing.

Breast, Prostate, and Colorectal Cancer Survivors' Experiences of Using Publicly Available Physical Activity Mobile Apps: Qualitative Study

BACKGROUND

Physical activity (PA) can improve a range of outcomes following a cancer diagnosis. These include an improvement in experience of side effects of treatment (eg, fatigue) and management of comorbid conditions. PA might also increase survival and reduce recurrence. Digital interventions have shown potential for PA promotion among cancer survivors, but most in a previous review were Web-based, and few studies used mobile apps. There are many PA apps available for general public use, but it is unclear whether these are suitable as a PA intervention after a cancer diagnosis.

OBJECTIVE

This study sought posttreatment nonmetastatic breast, prostate, and colorectal cancer survivors' opinions of using smartphone apps to promote PA and gathered their views on existing publicly available PA apps to inform a future intervention.

METHODS

Each participant was randomly assigned to download 2 of 4 apps (Human, The Walk, The Johnson & Johnson Official 7 Minute Workout, and Gorilla Workout). Participants used each app for 1 week consecutively. In-depth semistructured telephone interviews were then conducted to understand participants' experiences of using the apps and how app-based PA interventions could be developed for cancer survivors. The interviews were analyzed using thematic analysis.

RESULTS

Thirty-two participants took part: 50% (16/32) had prostate cancer, 25% (8/32) had breast cancer, and 25% (8/32) had colorectal cancer. Three core themes were identified. The first theme was that multiple factors affect engagement with PA apps and this is highly personalized. Factors affecting engagement included participants' perceptions of (1) the advantages and disadvantages of using apps to support PA, (2) the relevance of the app to the user (eg, in terms of cancer-related factors, their PA goals, the difficulty level of the app, the way in which they interact with their mobile phone, and the extent to which the app fits with their self-identity), (3) the quality of the app (eg, usability, accuracy, quality of production, and scientific evidence-base), and (4) the behavior change techniques used to promote PA. In the second theme, participants recommended that apps that promote walking are most appealing, as walking removes many barriers to PA. Finally, the participants suggested that PA apps should be integrated into cancer care, as they valued guidance and recommendations from health care professionals.

CONCLUSIONS

This sample of breast, prostate, and colorectal cancer survivors was receptive to the use of apps to promote PA. Although no publicly available PA app was deemed wholly suitable, many suggestions for adaptation and intervention development were provided. The results can inform the development of an app-based PA intervention for cancer survivors. They also highlight the wide-ranging and dynamic influences on engagement with digital interventions, which can be applied to other evaluations of mobile health products in other health conditions and other health behaviors.

Systematic review and meta-analysis of distance-based physical activity interventions for cancer survivors (2013-2018): We still haven't found what we're looking for

BACKGROUND

Physically active cancer survivors have a reduced risk of cancer recurrence and mortality. Given the health advantages of active lifestyles in cancer survivorship, as well as the barriers preventing physical activity (e.g., geography, time) there is a need to develop and evaluate effective physical activity interventions that employ distance-based (i.e., non face-to-face) approaches. The primary objective of this study was to provide a systematic review and meta-analysis of present-day (2013-2018) distance-based physical activity behaviour change interventions for cancer survivors.

METHODS

PubMed and Embase databases were searched from November 2012 up to June 2018. Studies were included that met the following criteria: (1) written in English, (2) included adult cancer survivors (either undergoing or completed treatment), (3) was a controlled intervention study, and (4) the intervention was distance-based (delivered via distance) with no more than one face-to-face contact. Review Manager 5 (RevMan 5) software was used to perform a meta-analysis on all randomized controlled trials (RCTs) that presented self-reported or objectively measured physical activity post-intervention means and standard deviations. Risk of bias for each study was assessed using The Cochrane Risk of Bias Tool.

RESULTS

We included 29 RCTs. Across the 29 studies, the total number of participants in these studies was 5218. Median sample size was 95 and ranged from 19 to 463. Thirteen (45%) studies focused on breast cancer survivors and median months since diagnosis was 24 (range 6-79). Moderate-to-vigorous intensity physical activity data from 24 RCTs were included in the meta-analysis and indicated an overall small effect (standardized mean difference) of 0.21 (95% CI 0.11-0.32) favoring the interventions.

CONCLUSIONS

Intervention effects on physical activity were small. Drawing conclusions from these trials remains challenging given major limitations of these trials included poor methodological design, small sample sizes, lack of statistical power, homogeneous samples (e.g., caucasian, young, well-educated), and poor measures of physical activity (e.g., self-report). Relying on the present landscape of distance-based programs aiming to facilitate physical activity among cancer survivors may not be prudent.

Connecting people with cancer to physical activity and exercise programs: a pathway to create accessibility and engagement

Recent guidelines concerning exercise for people with cancer provide evidence-based direction for exercise assessment and prescription for clinicians and their patients. Although the guidelines promote exercise integration into clinical care for people with cancer, they do not support strategies for bridging the guidelines with related resources or programs. Exercise program accessibility remains a challenge in implementing the guidelines, but that challenge might be mitigated with conceptual frameworks ("pathways") that connect patients with exercise-related resources. In the present paper, we describe a pathway model and related resources that were developed by an expert panel of practitioners and researchers in the field of exercise and rehabilitation in oncology and that support the transition from health care practitioner to exercise programs or services for people with cancer. The model acknowledges the nuanced distinctions between research and exercise programming, as well as physical activity promotion, that, depending on the available programming in the local community or region, might influence practitioner use. Furthermore, the pathway identifies and provides examples of processes for referral, screening, medical clearance, and programming for people after a cancer diagnosis. The pathway supports the implementation of exercise guidelines and should serve as a model of enhanced care delivery to increase the health and well-being of people with cancer.
