Relationship between physical activity,disability, and physical fitness profile in sedentary Latina breast cancer survivors

Objective: To report baseline data from a physical activity (PA) intervention for Latina breast cancer survivors, and assess the relationship between PA, fitness, and disability. Methods: Eighty-nine Latina breast cancer survivors from San Juan, PR and Houston, TX (age: 55.4 ± 9.9 years; BMI: 29.87 ± 5.62 kg/m²; ≥ 3 months post-treatment) participated in this study. At baseline participants completed fitness testing (six-minute walk test [6MWT], 30-second sit-stand; grip strength, lower and upper extremity and low back strength, shoulder range of motion, balance testing), and assessment of physical activity (PA) and disability. PA was assessed using the International Physical Activity Questionnaire (IPAQ). A subsample (n = 27) received an accelerometer to compare objective versus self-reported PA. Results: Participants exhibited low PA (M = 76.5 MET·minutes/week; SD = 183.4), poor fitness (6MWT M = 436.4 meters, SD = 99.1; 30s sit-stand, M = 11.6 stands, SD = 3.1), and no detectable disability. In an adjusted model lower extremity fitness was associated with PA, with a one repetition increase in sit-to-stand associated with 49 additional minutes of self-reported PA plus walking per week. The correlation between IPAQ moderate-vigorous PA and accelerometer was 0.38 (p = 0.047). Conclusion: Latina breast cancer survivors have low physical activity and fitness levels that increase their risk of disability, cardiometabolic comorbidities, and potential cancer recurrence.     

A Home-Based Exercise Program to Improve Function,Fatigue, and Sleep Quality in Patients With Stage IV Lung and Colorectal Cancer: A Randomized Controlled Trial

ContextExercise benefits patients with cancer, but studies of home-based approaches, particularly among those with Stage IV disease, remain small and exploratory.ObjectivesTo conduct an adequately powered trial of a home-based exercise intervention that can be facilely integrated into established delivery and reimbursement structures.MethodsSixty-six adults with Stage IV lung or colorectal cancer were randomized, in an eight-week trial, to usual care or incremental walking and home-based strength training. The exercising participants were instructed during a single physiotherapy visit and subsequently exercised four days or more per week; training and step-count goals were advanced during bimonthly telephone calls. The primary outcome measure was mobility assessed with the Ambulatory Post Acute Care Basic Mobility Short Form. Secondary outcomes included ratings of pain and sleep quality as well as the ability to perform daily activities (Ambulatory Post Acute Care Daily Activities Short Form), quality of life (Functional Assessment of Cancer Therapy-General), and fatigue (Functional Assessment of Cancer Therapy-Fatigue).ResultsThree participants dropped out and seven died (five in the intervention and two in the control group, P = 0.28). At Week 8, the intervention group reported improved mobility (P = 0.01), fatigue (P = 0.02), and sleep quality (P = 0.05) compared with the usual care group, but did not differ on the other measures.ConclusionA home-based exercise program seems capable of improving the mobility, fatigue, and sleep quality of patients with Stage IV lung and colorectal cancer.     

Exercise intervention and health checks for middle-aged men with elevated cardiovascular risk: A randomized controlled trial

Abstract

Objective. To study the effects of a health check by a nurse alone or combined with an exercise intervention in middle-aged men at increased cardiovascular risk. Design. A randomized controlled trial. Setting and intervention. Primary care in Kirkkonummi municipality with 36 000 inhabitants. A health check by a nurse alone or combined with an exercise intervention to controls with no intervention was compared. Subjects. A total of 168 men aged 35 to 45 years with at least two cardiovascular risk factors and physical activity (PA) frequency < 3 times a week. Main outcome measures. Metabolic syndrome (MetS) as defined by International Diabetes Federation/American Heart Association and self-reported PA frequency. Results. Overall, focusing on health increased physical activity frequency in middle-aged men. After one year, 19% had increased PA to ≥ 3 times a week (95% CI 12–26). All study groups increased PA to ≥ 3 times: 26% of men in the exercise intervention group, 15% of men in the health check group, and 16% of controls. The differences between the groups were not statistically significant. The intervention did not have any meaningful impact on MetS or other cardiovascular outcomes at one-year follow up. Conclusions. Physical activity increased in all study groups of middle-aged men in this health-promotion trial. The interventions had no effect on metabolic syndrome or other cardiovascular outcomes in the participants. The trial increased awareness and collaboration in physical activity promotion among municipal health care and exercise services.     

Effect of treadmill testing and exercise training on self-efficacy in patients with heart failure.

BACKGROUND: Self-efficacy is a person's confidence in being able to successfully perform a specific activity or behavior. Self-efficacy has been shown to influence exercise capacity in patients post myocardial infarction, but has not been fully explored in patients with heart failure (HF). This study examined the impact of performance of a single treadmill exercise test and participation in a 3-month program of walking and resistance exercise on self-efficacy in HF patients. METHODS: 24 patients were randomized to either a home-based walking and resistance exercise program or usual care for 3 months. Prior to enrollment into the exercise program all participants performed a single treadmill exercise test with respiratory gas analysis. Self-efficacy questionnaires were completed at 3 time points, 1) prior to performance of an exercise treadmill test; 2) immediately after completing an exercise test; and 3) at the end of a 3-month exercise program. RESULTS: Self-efficacy for walking (p=0.07), climbing (p=0.17), lifting (p=0.73) and general activity (p=0.15) did not improve after performance of a single treadmill exercise test and usual care. However, self-efficacy for walking increased after 3 months of a walking and resistance exercise program. (p=0.04). CONCLUSIONS: The findings from this study suggest that in patients with stable mild to moderate heart failure, self-efficacy is improved with participation in a home-based walking and endurance exercise program. Self-efficacy is not enhanced by performance of a single treadmill exercise test and usual care.     

The feasibility and acceptability of a diet and exercise trial in overweight and obese black breast cancer survivors: The Stepping STONE study

PurposeBlack breast cancer survivors have high rates of obesity and low physical activity levels. Little is known about the acceptability and feasibility of interventions in this population.ObjectiveA two-arm RCT was launched to assess the efficacy of a culturally targeted 12-week multimodal lifestyle intervention in overweight and obese black survivors.MethodsIntervention components included nutrition education, exercise groups, and survivor-led motivational interviewing phone sessions. The analytic sample included women who completed the trial (intervention n = 10; control n = 12). Anthropometric measures, physical activity, and VO_2max were assessed at baseline and follow-up. Change scores (intervention vs. control) were assessed with Wilcoxon rank-sum tests. A process evaluation assessed intervention acceptability.ResultsOverall adherence was 70% and overall satisfaction was high (86%). Despite the 5% weight loss target, the intervention group lost 0.8% but BMI improved. Total physical activity levels increased in the intervention vs. control arm (+ 3501 MET min/week vs. + 965 MET min/week, respectively). VO_2max improved in the intervention group (+ 0.10 ± 1.03 kg/L/min). Intervention participants reduced energy intake (− 207.3 ± 31.5 kcals) and showed improvements in fat intake (− 15.5 ± 3.8 g), fiber (+ 3.2 ± 1.2 g) and % energy from fat (− 4.8 ± 3.1%). Survivors suggested providing diet/exercise information within a cancer context.ConclusionsGroup and individualized intervention strategies are acceptable to black survivors. Observed differences between self-report and objective outcomes may suggest reporting bias or changes in body composition. Increasing supervised intervention components and assessment of body composition will be important for future trials.     

Effectiveness of a home-based exercise program among patients with lower limb spasticity post-stroke: A randomized controlled trial

PurposeTo evaluate the effectiveness of advanced practice nurse–guided home-based rehabilitation exercise program (HREPro) among patients with lower limb spasticity post-stroke.MethodsThis randomized controlled study recruited 121 patients with lower limb spasticity post-stroke. Intervention (n = 59) and control (n = 62) groups underwent 12-month HREPro and conventional rehabilitation, respectively, after discharge. The Fugl–Meyer assessment of spasticity measurement, modified Ashworth scale of motor function, 10-Meter Walk Test of walking ability, and Barthel index of activities of daily living (ADL) were evaluated at 0, 3, 6, and 12 months after discharge.ResultsSignificant differences were found in spasticity degree, motor function, walking ability, and ADL at 6 and 12 months after discharge between the control and intervention groups. Lower limb spasticity and ADL in the intervention group were significantly improved.ConclusionHREPro is effective for rehabilitation of patients with lower limb spasticity post-stroke and has favorable home application.     

Effectiveness of a combined exercise training and home-based walking programme on physical activity compared with standard medical care in moderate COPD: a randomised controlled trial

Objective

To estimate the effectiveness of a 10-week combined exercise training and home-based walking programme on daily physical activity (PA) compared with standard medical care in patients with moderate chronic obstructive pulmonary disease (COPD).

Circuit-Based Rehabilitation Improves Gait Endurance but Not Usual Walking Activity in Chronic Stroke: A Randomized Controlled Trial

Mudge S, Barber PA, Stott NS. Circuit-based rehabilitation improves gait endurance but not usual walking activity in chronic stroke: a randomized controlled trial.

Objective

To determine whether circuit-based rehabilitation would increase the amount and rate that individuals with stroke walk in their usual environments.

Design

Single-blind randomized controlled trial.

Setting

Rehabilitation clinic.

Participants

Sixty participants with a residual gait deficit at least 6 months after stroke originally enrolled in the study. Two withdrew in the initial phase, leaving 58 participants (median age, 71.5y; range, 39.0–89.0y) who were randomized to the 2 intervention groups.

Interventions

The exercise group had 12 sessions of clinic-based rehabilitation delivered in a circuit class designed to improve walking. The control group received a comparable duration of group social and educational classes.

Main Outcome Measures

Usual walking performance was assessed using the StepWatch Activity Monitor. Clinical tests were gait speed (timed 10-meter walk) and endurance (six-minute walk test [6MWT]), confidence (Activities-Based Confidence Scale), self-reported mobility (Rivermead Mobility Index [RMI]), and self-reported physical activity (Physical Activity and Disability Scale).

Results

Intention-to-treat analysis revealed that the exercise group showed a significantly greater distance for the 6MWT than the control group immediately after the intervention (P=.030) but that this effect was not retained 3 months later. There were no changes in the StepWatch measures of usual walking performance for either group. The exercise and control groups had significantly different gait speed (P=.038) and scores on the RMI (P=.025) at the 3-month follow-up. These differences represented a greater decline in the control group compared with the exercise group for both outcome measures.

Conclusions

Circuit-based rehabilitation leads to improvements in gait endurance but does not change the amount or rate of walking performance in usual environments. Clinical gains made by the exercise group were lost 3 months later. Future studies should consider whether rehabilitation needs to occur in usual environments to improve walking performance.     

The Perspectives and Lived Experience of Postoperative Patients with Lung Cancer Participating in a Home-Based Exercise Intervention

ObjectivesPostoperative patients with lung cancer experience a cluster of symptoms and reduced quality of life. This study aimed to collect the pre- and postexercise intervention opinions of postoperative patients with lung cancer and to identify their perceptions of barriers, facilitators, and benefits of a home-based exercise intervention and its impact on their future exercise.Data SourcesFourteen participants (aged 53 to 78) were purposively recruited from a tertiary hospital to participate in a 4-week home-based walking exercise intervention after discharge. Semi-structured, one-on-one interviews were conducted to collect data. The interviews were transcribed verbatim, and the data were analyzed using a thematic analysis approach. Details regarding the exercise duration and intensity for each participant were collected using a sports watch app, and participants exercise diaries.ConclusionThree main themes emerged: (1) participants’ differing opinions preintervention, (2) barriers and facilitators encountered during the exercise period, and (3) the positive impact on participants’ future exercise. Other results showed that 12 of the 14 participants reached the goal of exercise duration and intensity. Postoperative patients with lung cancer need an exercise intervention to motivate and guide them to perform exercise after discharge. This study showed that a home-based walking exercise intervention was feasible and acceptable; patients perceived benefits and became more active and confident about their future exercise plans.Implications for Nursing PracticeAgainst the backdrop of inadequate staffing, insufficient funding, and lack of supervised exercise programs for this rapidly increasing population, this study of a nurse-led home-based exercise program provides a feasible and realistic approach and qualitative evidence to address these issues.     

The Group Oriented Arterial Leg Study (GOALS) to improve walking performance in patients with peripheral arterial disease

People with lower extremity peripheral artery disease (PAD) have greater functional impairment and faster functional decline than those without PAD. We describe methods for the Group Oriented Arterial Leg Study (GOALS), an ongoing randomized controlled clinical trial designed to determine whether a Group-Mediated Cognitive Behavioral (GMCB) intervention improves functional performance in PAD participants, compared to a health education control condition.In GOALS, PAD participants were randomized to either an intervention or a health education control condition in a parallel design. Both conditions consist of weekly group sessions with other PAD participants. In the intervention, cognitive behavioral techniques are used to assist participants in setting and adhering to home-based walking exercise goals. Participants are encouraged to walk for exercise at home at least 5 days/week. In the control condition, participants receive lectures on health-related topics. After 6 months of on-site weekly sessions, participants are transitioned to telephone follow-up for another 6 months. Participants in the intervention are asked to continue home walking exercise. The primary outcome is change in six-minute walk performance between baseline and six-month follow-up. Secondary outcomes include change in six-minute walk performance at 12-month follow-up, and change in treadmill walking performance, the Walking Impairment Questionnaire, quality of life, and physical activity at six and 12-month follow-up. In conclusion, if our group-mediated cognitive behavioral intervention is associated with improved walking performance in individuals with PAD, results will have major public health implications for the large and growing number of people with PAD.

Effects of a range-of-motion exercise programme

AIM: This paper reports an evaluation of a range-of-motion exercise programme aimed at improving joint flexibility, activity function, perception of pain, and depressive symptoms in a sample of stroke survivors in long-term care facilities. BACKGROUND: The benefits of physical rehabilitation for stroke survivors have been well established. There is, however, little empirical data on the effects of a simple nurse-led range-of-motion exercise programme in improving function for these people. METHOD: A randomized controlled trial was conducted in 1999 with 59 bedridden older stroke survivors in residential care. Participants were randomly assigned to usual care or one of two intervention groups. The 4-week, twice-per-day, 6 days-per-week range-of-motion exercise protocols were similar in both intervention groups, and consisted of full range-of-motion exercises of the upper and lower extremities. To test the effect of different degrees of staff involvement, in intervention group I, a Registered Nurse was present to supervise participants performing the exercises, while intervention group II involved a Registered Nurse physically assisting participants to achieve maximum range-of-motion within or beyond their present abilities. RESULTS: Both intervention groups had statistically significant improvement in joint angles, activity function, perception of pain and depressive symptoms compared with the usual care group (P < 0.05). Post hoc comparison revealed that the joint angles in intervention group II were statistically significantly wider than in both the other groups (P < 0.01). CONCLUSIONS: A simple nurse-led range-of-motion exercise programme can generate positive effects in enhancing physical and psychological function of bedridden older people with stroke. Further studies are needed to investigate the long-term effects of the programme in maximizing function, reducing care utilization and enhancing quality of life for this population.     

Camina por Salud: Walking in Mexican-American women

Forty-six percent of older Mexican-American women report that they do not engage in leisure time physical activity (PA); 38.1% of them are obese. This study (1) evaluated a PA intervention for coronary heart disease risk reduction and (2) determined which variables affect adherence to PA. For 36 weeks, Group I members walked for 3 days a week and Group II members walked for 5 days a week. We measured the participants' total body fat, regional fat, blood lipids, and adherence to PA The walking interventions favorably affected body fat, with significant differences in body mass index reduction, F(2, 16) = 12.86, p = .001. No statistical difference was noted in the anthropometric and blood lipid results between the baseline and 36-week measures.     

Impact of an educational intervention on internal medicine residents' physical activity counselling: the Pressure System Model

Rationale, aims and objectives Systematic reviews point to inconclusive evidence that counselling patients in a primary care setting is effective in increasing adults’ physical activity (PA) levels. This study evaluates the impact of an innovative physician counselling programme on physicians’ PA counselling behaviour and their patients’ PA levels. Methods A controlled educational study conducted at six Yale School of Medicine hospitals. Sixty‐five internal medicine residents and 316 primary care patients were randomized to intervention or control groups. Intervention physicians participated in five interactive sessions outlining details of the Pressure System Model, while control physicians received usual residency training. Intervention and control patients’ PA levels and residents counselling behaviour were assessed using a validated questionnaire and compared pre‐ and post intervention. Data analysis was performed using paired t‐tests and repeated measures anova . Results At 6‐month follow‐up intervention, patients’ PA levels increased significantly from baseline (1.77 ± 0.84; P = 0.0376). A similar pattern was observed after 12 months (1.94 ± 0.98; P = 0.0486). Control patients’ PA did not change significantly from baseline at 6 or 12 months (0.35 ± 1.00; P = 0.7224 and 0.99 ± 1.52; P = 0.5160, respectively). At 12 months, intervention residents provided PA counselling 1.5 times more than they did at baseline (P < 0.05) compared with no significant changes in the control group. Conclusions The present study has shown that providing residents with a practical tool, enabling them to deal with patients’ barriers and previous failure in behavioural change, is efficacious in increasing PA levels of adult patients.     

Integrative Review of Nurse-delivered Community-Based Physical Activity Promotion

PurposeThe purpose of this integrative review is to 1) describe intervention attributes, 2) describe the role of nurses in community PA promotion, and 3) describe the efficacy of the interventions in terms of PA behavior change.MethodsComputerized database and ancestry search strategies located distinct intervention trials between 1990 and 2015.ResultsThirteen national and international studies with 2,353 participants were reviewed. Multi-dose, face-to-face, group-based interventions with or without individual-based contacts for 6 months or less were the most common intervention delivery modes. Only 40% (n = 5) of the studies integrated health behavior theory into intervention design. Less than half of the studies demonstrated efficacy in increasing PA.ConclusionsResults suggest that group-based community interventions, such as exercise classes, group walking and group education/counseling, may be more effective in increasing PA compared to individual-based education. Additional rigorously designed studies are warranted to explore the indicators for successful community-based PA promotion.     

Self‐management program for obesity control among middle‐aged women in Korea: A pilot study

Aim: The aim of this study was to determine the effectiveness of a 12 week self‐management intervention program, as compared to a structured exercise intervention, for obesity control among middle‐aged women in Korea. Methods: A quasi‐experimental study was conducted with 27 women in a self‐management group and 24 in a structured exercise group for 12 weeks. The self‐management group received interventions that included walking at a convenient time and place, keeping healthy dietary habits, group workshops, phone counseling, and mobile phone short message services. The structured exercise group received a structured exercise intervention, which involved three 1 h walking classes per week at the health center. Both groups received baseline assessments before starting the interventions and at 12 weeks. The data were analyzed by using two sample t‐tests, a paired t‐test, and the χ²‐test. Results: After 12 weeks, there were significant changes in the health behavior, amount of body fat, and blood pressure of the participants in both intervention groups, but there was no significant difference in their body composition, blood profile, or blood pressure. Conclusion: Both the self‐management and the structured exercise programs were effective in controlling obesity in middle‐aged obese women in Korea. However, considering the chronic nature of obesity, the self‐management program would be more beneficial, compared to the structured exercise program, as it allows people to exercise at a convenient time and place and to learn how to cope with their lifestyle barriers.     

Effect of feedback in promoting adherence to an exercise programme: a randomized controlled trial

Objective We investigated whether providing participants in an exercise programme with regular feedback on their exercise progress affected their adherence to the programme regimen. Method We conducted a randomized controlled trial. Adult men and women with borderline hypertension and a body mass index ≥ 25.0 were randomized to two intervention groups (groups A and B) and one control group (group C) and were prescribed regular aerobic exercise. During the 12‐week study period, group A was provided with both feedback information on their exercise progress and a health letter, while group B was provided with the health letter only. The main outcome measure was exercise performance, per cent achievement of target exercise level (%) defined as the number of weeks during which the exercise target was reached divided by the number of weeks in the programme. Results were compared using the Kruskal–Wallis test. Results A total of 105 study subjects were randomized into three groups (A, n = 37; B, n = 37 and C, n = 31). Per cent achievement of target exercise level during the 12‐week period was highest in group A (26.5%), followed by groups B (22.9%) and C (17.4%) (P = 0.36). Subjects who received regular feedback during the exercise programme tended to have higher exercise performance. Conclusions In improving adherence to exercise intervention, the provision of regular feedback to participants in an exercise programme may be an effective intervention.     

Experimental protocol of a randomized controlled clinical trial investigating exercise,subclinical atherosclerosis,and walking mobility in persons with multiple sclerosis

BackgroundThis randomized controlled trial (RCT) will investigate the effects of a home-based aerobic exercise training regimen (i.e., cycle ergometry) on subclinical atherosclerosis and walking mobility in persons with multiple sclerosis (MS) and minimal disability.Methods/designThis RCT will recruit 54 men and women who have an Expanded Disability Status Scale characteristic of the 1st stage of MS (i.e., 0–4.0) to participate in a 3 month exercise or stretching intervention, with assessments of subclinical atherosclerosis and walking mobility conducted at baseline, week 6 (midpoint), and week 12 (conclusion) of the program. The exercise intervention will consist of 3 days/week of cycling, with a gradual increase of duration followed by an increase in intensity across the 3 month period. The attention-control condition will incorporate stretching activities and will require the same contact time commitment as the exercise condition. Both study groups will participate in weekly video chat sessions with study personnel in order to monitor and track program adherence. Primary outcomes will consist of assessments of vascular structure and function, as well as several walking tasks. Additional outcomes will include questionnaires, cardiorespiratory fitness assessment, and a 1-week free-living physical activity assessment.DiscussionThis investigation will increase understanding of the role of aerobic exercise as part of a treatment plan for managing subclinical atherosclerosis and improving walking mobility persons in the 1st stage of MS. Overall, this study design has the potential to lead to effective aerobic exercise intervention strategies for this population and improve program adherence.     

Maintenance of effects of a home-based physical activity program among breast cancer survivors

Purpose  Although physical activity (PA) adoption improves fitness and psychological well-being among cancer survivors, PA maintenance has not been examined. This paper presents follow-up of a home-based PA program for women treated for early-stage breast cancer. Materials and methods  Eighty-six sedentary women (mean age = 53.14 years, SD = 9.70) were randomly assigned to a PA or contact control group. The PA group received a 12-week telephone counseling program to adopt PA. Assessments were conducted at baseline, end-of-intervention (12 weeks), 6, and 9 months post-baseline. Results  When comparing change from end-of-intervention (12 weeks) between groups, a significant reduction was observed in minutes of PA at 6 months (t = −2.10, p < 0.05), but there was no decrease in intervention effect at 9 months (t = −0.19, p = 0.84). Similarly, post-intervention reductions in fatigue were lost at 6 months (t = 3.27, p < 0.01), but remained present at 9 months (t = 1.65, p = 0.10). PA group’s fitness improvements were maintained at both follow-ups (t = 1.04, p = 0.30 and t = 0.05, p = 0.96). The previously significant intervention effect on vigor was maintained at 6 months (t = 1.32, p = 0.19) but was significantly reduced at 9 months (t = −2.15, p < 0.05). PA participants were more likely to progress in motivational readiness at 6 (OR = 5.95, 95% CI = 2.30, 15.36) and 9 months (OR = 4.09, 95% CI = 1.69, 9.87); however, group differences in meeting PA guidelines were not maintained. Conclusion  Some positive effects of a home-based PA intervention for breast cancer patients were maintained at 6 and 9 months.
