Comparing the efficacy of a multi-dimensional breast cancer rehabilitation programme versus a home-based exercise programme during adjuvant cancer treatment

BackgroundBreast cancer is the most common female malignancy worldwide and a major cause of morbidity and mortality. Exercise during adjuvant treatment improves function and relieves symptoms in breast cancer survivors. However, it is unclear if an unsupervised exercise programme may be as effective as a supervised multimodal group. We investigated the feasibility and efficacy of a centre-based multidimensional rehabilitation (MDR) programme for breast cancer survivors undergoing adjuvant treatment and compared it to an unsupervised home-based exercise (HE) programme.MethodsParticipants were self-allocated to either MDR or HE group. MDR participants underwent 24 supervised exercise classes and 10 education classes over 12 weeks. HE participants were instructed on a home exercise regime. Outcome measures, including the 6-min walk test (6MWT) and Frenchay Activities Index (FAI), FACT-Cognitive Function scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, were conducted at baseline (W0), post-intervention (W12) and 6-months post-intervention (M6). Variance between time points and the 2 groups were analysed using a linear mixed model (unstructured covariance matrix) and adjusted with Bonferroni.ResultTwenty-five participants attended at least half of the MDR interventions, while 21 completed the HE interventions. The former showed significant improvement in 6MWT, from 406.88 m (W0) to 443.34 m (W12) to 452.81 m (M6), while the improvement in the HE group was not significant (407.67 m (W0) to 433.14 m (W12) to 430.96 m (M6)). Both groups showed a significant improvement in FAI, with earlier significant improvement noted at W12 in the MDR group (22.71 (W0) to 27.65 (W12) to 28.81 (M6)) compared to the HE group (23.16 (W0) to 26.47 (W12) to 29.85 (M6)). Dropout rate was 16% in the MDR group and 34% in HE group. Overall satisfaction with the MDR programme was high.ConclusionBoth MDR and HE programmes were feasible. MDR was superior in improving endurance and earlier return to instrumental activities for those who completed at least half of the sessions. Future studies could explore use of technology to improve adherence to exercise.Trial registrationThe study was registered with ClinicalTrial.gov on 01/04/2022 with the registration number NCT05306808.

The effects of unsupervised home-based exercise training during pregnancy: A systematic review.

Pregnant women may experience physical and emotional distress. Exercise is recommended for healthy pregnant women and is beneficial for their mental and physical health. Unsupervised home-based exercise is cost-effective for pregnant women as an occasional solution for their discomfort. However, no synthesis of randomized trials on this topic has been conducted. The aim of this study was to evaluate the effectiveness of unsupervised home-based exercise during pregnancy. A systematic search for randomized controlled trials was performed in electronic databases. The review extracted eligibility criteria based on unsupervised home-based exercise intervention. The quality of the included studies was performed using the Cochrane Risk of Bias Tool 2.0. This review was registered a priori in PROSPERO (CRD42023452966). In total, seven studies were selected for systematic review. Participant adherence rates for the three reported studies varied considerably, ranging from 33% to 75%. Two studies revealed that unsupervised home-based exercise improved symptom severity in relation to long-term adherence to exercise. Two studies suggested that maternal aerobic fitness increased due to exercise. One study revealed improved sleep quality. However, none of the studies supported the positive effects of exercise on fatigue, maternal insulin sensitivity, prenatal weight gain, postnatal weight loss, birth pain, and cesarean section. Unsupervised home-based exercise improves discomfort symptoms during pregnancy but requires a long intervention period. This finding suggests that the evaluation period needs to be longer to identify the effects of exercise. In addition, a theoretical-based integrity exercise plan should be considered to promote the effectiveness of unsupervised home-based exercise.

Vigorous vs. moderate exercise to improve glucose metabolism in inactive women with polycystic ovary syndrome and insulin resistance: a pilot randomized controlled trial of two home-based exercise routines

To study the impact of vigorous vs. moderate exercise on metabolic parameters in polycystic ovary syndrome (PCOS). Randomized controlled trial. Unsupervised home-based exercise program. Patients with PCOS on the basis of the Rotterdam criteria with insulin resistance. Participants were block randomized to a home-based exercise program of 75 minutes of vigorous exercise or 150 minutes of moderate exercise per week, for 8 weeks total. Changes in glucose, insulin, and insulin resistance. In total, 36 participants were randomized, of whom 20 completed the study. The percentage changes from baseline at 4 and 8weeks for fasting glucose, insulin, and homeostatic model assessment for insulin resistance did not significantly differ between the groups, except for the change in the 8-week glucose level, which was more favorable in the moderate arm (8.06% [standard deviation, 6.44%] in the vigorous group compared with -0.32% [standard deviation, 4.91%] in the moderate group). The absolute values of the main outcomes (fasting glucose, insulin, and homeostatic model assessment for insulin resistance) at baseline and 4 and 8 weeks did not significantly differ between trial arms. When assessing the change from baseline at 4 and 8 weeks, overall and within each trial arm, only the 8-week fasting glucose level was significantly greater than the baseline value in the vigorous arm (93.5 [95% confidence interval, 88.7-98.3] vs. 86.8 [95% confidence interval, 81.1-92.4]). Unsupervised short-term exercise programs may not achieve significant metabolic improvements in patients with PCOS, regardless of vigorous vs. moderate intensity. Future studies should investigate this question in larger sample sizes and longer or structured exercise programs. ClinicalTrials.gov identifier, NCT02303470.

Cost and outcomes of Hospital-based Usual cAre versus Tele-monitor self-directed Rehabilitation (HUATR) in patients with total knee arthroplasty: A randomized, controlled, non-inferiority trial

To evaluate the clinical efficacy and cost-effectiveness of telemonitored self-directed rehabilitation (TR) compared with hospital-based rehabilitation (HBR) for patients with total knee arthroplasty (TKA). In this randomized, non-inferiority clinical trial, 114 patients with primary TKA who were able to walk independently preoperatively were randomized to receive HBR (n=58) or TR (n=56). HBR comprised at least five physical therapy sessions over 10weeks. TR comprised a therapist-led onboarding session, followed by a 10-week unsupervised home-based exercise program, with asynchronous monitoring of rehabilitation outcomes using a telemonitoring system. The primary outcome was fast-paced gait speed at 12weeks, with a non-inferiority margin of 0.10m/s. For economic analysis, quality-adjusted-life-years (QALY) was the primary economic outcome (non-inferiority margin, 0.027 points). In Bayesian analyses, TR had >95% posterior probability of being non-inferior to HBR in gait speed (week-12 adjusted TR-HBR difference, 0.02m/s; 95%CrI, -0.05 to 0.10m/s; week-24 difference, 0.01m/s; 95%CrI, -0.07 to 0.10m/s) and QALY (0.006 points; 95%CrI, -0.006 to 0.018 points). When evaluated from a societal perspective, TR was associated with lower mean intervention cost (adjusted TR-HBR difference, -S$227; 95%CrI, -112 to -330) after 24weeks, with 82% probability of being cost-effective compared with HBR at a willingness to pay of S$0/unit of effect for the QALYs. In patients with uncomplicated TKAs and relatively good preoperative physical function, home-based, self-directed TR was non-inferior to and more cost-effective than HBR over a 24-week follow-up period. TR should be considered for this patient subgroup.

The Effects of Exercise Training on Exercise Capacity and Vascular Function after Transcatheter Aortic Valve Implantation-A Pilot Study.

Transcatheter aortic valve implantation (TAVI) improves event-free survival in patients with severe aortic stenosis, but patients' exercise capacity remains poor after the procedure. Therefore, we sought to compare the effects of a supervised center-based exercise training program and unsupervised exercise routine on exercise capacity and vascular function in patients after TAVI. Patients were randomized to either center-based exercise training (12-24 sessions of combined aerobic and low-weight resistance training twice weekly for 8-12 weeks) or an unsupervised home-based exercise routine (initial appraisal with detailed recommendations and monthly follow-up). Exercise capacity (cardiopulmonary testing) and vascular function (ultrasonographic measurement of flow-mediated vasodilation (FMD) and arterial stiffness) were assessed at the baseline and after the study period. We included 23 patients (mean age of 81 years, 61% women), with higher-than-expected drop-out rates (41%) because of the coronavirus-19 pandemic outbreak. Exercise capacity improved over time, irrespective of the intervention group: 0.09 mL/min/kg increase in peak oxygen uptake (95% CI [0.01-0.16]; p = 0.02), 8.2 Watts increase in workload (95% CI [0.6-15.8]; p = 0.034), and 47 s increase in cumulative exercise time (95% CI [5.0-89.6]; p = 0.029). A between-group difference in change over time (treatment effect) was detected only for FMD (4.49%; 95% CI [2.35; 6.63], p < 0.001), but not for other outcome variables. Both supervised and unsupervised exercise training improve exercise capacity and vascular function in patients after TAVI, with supervised exercise training possibly yielding larger improvements in vascular function, as determined by FMD.

Effects of Home-Based Exercise Programs on Mobility, Muscle Strength, Balance, and Gait in Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis.

Individual unsupervised home-based exercise programs can enhance muscle strength, physical function, gait, and balance in older adults. However, the effectiveness of such programs may be limited by the lack of supervision. This study aims to verify the effectiveness of individual unsupervised home-based programs, compare the effects of individual unsupervised home-based to supervised programs, and verify the influence of supervision over individual unsupervised home-based programs on the physical function of older adults. A systematic literature search was performed in four electronic databases, and the trials involved randomized controlled comparing the home-based programs to supervised, control groups, or home-based + supervised evaluating the muscle strength, physical function, gait, and balance in older adults. Eleven studies met the inclusion criteria. The meta-analysis revealed no differences between home-based program versus supervised program in gait, mobility, and balance, revealing a trend of significance to supervised program on strength (standardized mean difference [SMD] = 0.27, p = .05). The analysis revealed effects in mobility (SMD = 0.40, p = .003), balance (SMD = 0.58, p = .0002), and muscle strength (SMD = 0.36, p = .02) favoring home-based program versus control group. Significant effects between home-based program versus home-based + supervised program were observed in balance (SMD = 0.74, p = .002) and muscle strength (SMD = 0.58, p = .01) in favor of home-based + supervised program. Home-based programs effectively improve older adults' physical function compared with control groups. However, supervised programs were more effective for muscle strength.

Qualitative analysis of facilitators and barriers to centre- and home-based exercise training in breast cancer patients - a Swiss tertiary centre experience.

Exercise is an effective therapy for breast cancer patients to reduce fatigue and to improve health-related quality of life and physical function. Yet breast cancer patients often do not meet the recommended physical activity guidelines. To better understand why recommendations are not met and to improve long-term physical activity maintenance, this study aimed at identifying facilitators and barriers of breast cancer survivors to supervised, centre-based exercise within a cardio-oncological rehabilitation programme and to unsupervised, home-based exercise both during and after the completion of the programme, as well as strategies used to manage these barriers. Breast cancer patients who had previously completed a structured centre-based exercise programme at a Swiss tertiary centre were recruited by mailed invitation letter. Semi-structured telephone interviews were conducted with consenting patients and subsequent thematic analysis was performed to identify common themes. Of the 37 eligible breast cancer patients, 19 patients (51%, mean age 48.9 ± 9.7 years) responded to our invitation. Baseline characteristics did not differ from the total eligible population. General facilitators for exercise were anticipated and experienced benefits on physical and mental health and enjoyment of exercise. Facilitators specific for supervised centre-based exercise were social support, accountability and the provision of structured exercise by the programme. Centre-based exercise barriers included physical, psychological and environmental barriers, whereby psychological barriers were reported predominantly in the context of home-based exercise. Strategies to manage these barriers were diverse and included the adaptation of training circumstances, behaviour change strategies and strategies to deal with side effects. This first study on facilitators of and barriers to exercise in breast cancer patients in Switzerland identified more barriers, particularly psychological barriers, for unsupervised home-based exercise than for supervised centre-based exercise. These findings support the importance of providing structured supervised exercise programmes for breast cancer patients and suggest that a special focus should be directed at the transition from supervised to self-organized exercise in order to enhance and maintain long-term exercise participation.

Unsupervised Home-based Exercise for Rural Frail Elderly: An Evidence-based Case-report

ABSTRACT To summarize the literature investigating the efficacy of unsupervised home-based exercise (UHBE) in managing rural community-dwelling pre-frail and frail elders, we searched, appraised, and ranked eligible studies published until February 18, 2021 according to the level of evidence (LOE). From six randomized trials, we discovered that UHBE yielded favorable effects on frailty by improving strength (LOE II), quality-of-life (LOE II), and flexibility (LOE I–II). Furthermore, UHBE was generally non-inferior to supervised exercise, except in terms of strength (LOE II–III), balance (LOE IV), and physical function (LOE III–IV). As no trials were conducted in rural underdeveloped settings, future studies are warranted.

Exercise in patients with hip osteoarthritis – effects on muscle and functional performance: A randomized trial

ABSTRACT Background: It is believed that clinical management of osteoarthritis should address muscle weakness to improve physical function and prevent disability and frailty.Objectives: This sub-study investigated the effects of supervised progressive resistance training (RT), supervised Nordic Walking (NW), and unsupervised home-based exercise (HBE) on muscle and functional performance; and associations between these exercise-induced changes in persons with hip osteoarthritis. Methods: Forty-two patients with hip osteoarthritis were recruited from a larger RCT (NCT01387867). All the groups (RT, n = 15; NW, n = 12; HBE, n = 15) exercised 1 h 3 times/week for 4 months. Quadriceps cross-sectional area (QCSA, MRI-determined); quadriceps strength (QMVC); leg extensor power (LEP); functional performance (chair stands (30sCS); stair climbs (TSC); and 6-minute walk (6MWT)) were assessed at baseline and 4 months. Results: Per protocol analyses (one-way ANOVA and Bonferroni test) showed significant between-group differences for improvements in QCSA in the most symptomatic leg favoring RT versus NW (2.3 cm2, 95% CI [0.6, 3.9]) and HBE (2.3 cm2 [0.8, 3.9]); and 30sCS (1.8 repetitions [0.2–3.3]), and 6MWT (35.1 m [3.5–66.7]) favoring NW versus HBE. Associations existed between exercise-induced changes in QCSA and QMVC (r = 0.366, p = .019) for the most symptomatic leg and between changes in 6MWT and QMVC (r = 0.320, p = .04) and LEP (r = 0.381, p = .01), respectively, for the least symptomatic leg. Conclusions: Resistance training appeared effective for improving muscle mass, but less effective for improving muscle strength, power, and functional performance. Only exercise-induced changes in muscle strength and power of the least symptomatic leg, not the most symptomatic leg, were related to changes in functional performance.

The Effect of Unsupervised Home-Based Exercise Training on Physical Functioning Outcomes in Older Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Exercise training such as balance, aerobic, and resistance training is able to improve physical functioning of older adults. Delivering such exercise regimes at home without supervision may be useful for older adults because they do not have to leave their homes. This systematic review and meta-analysis of randomized controlled trials aimed to establish the effect of unsupervised home-based exercise training regimes on physical functioning (balance and muscle strength) in older adults. PubMed, CINAHL, Medline, Google Scholar, and Scopus databases and reference lists of included investigations were searched. Thirteen randomized controlled trials (RCTs) of exercise training impact on balance and upper body strength with concurrent control groups were included in the analysis. Our analyses revealed that in older adults, unsupervised home-based various exercise training was effective in improving measures of proactive balance (mean difference (MD) = -1.37 s; 95% confidence interval (CI), -2.24, -0.51 s; p = 0.002) and balance test battery (MD: 1.80; 95% CI, 0.46, 3.14 s; p = 0.009). There were no significant differences between the experimental and control groups for upper body strength (p > 0.05). Unsupervised home-based exercise training improves balance in older adults. Future investigations are needed to clarify the mechanisms underlying unsupervised home-based exercise training's effect on this population's physical functioning outcomes.

Exercise Snacking to Improve Muscle Function in Healthy Older Adults: A Pilot Study.

Loss of muscle mass and strength are seemingly accepted as part of the ageing process, despite ultimately leading to the loss of independence. Resistance exercise is considered to be primary defence against loss of muscle function in older age, but it typically requires access to exercise equipment often in a gym environment. This pilot study aimed at examining the effect of a 28-day, unsupervised home-based exercise intervention on indices of leg strength and muscle size in healthy older adults. Twenty participants were randomly assigned to either maintain their habitual physical activity levels (Control; n=10; age, 74 (5) years; body mass, 26.3 (3.5) kg/m2) or undertake “exercise snacks” twice daily (ES; n=10; age, 70 (4) years; body mass, 25.0 (3.4) kg/m2). Both groups consumed 150 g of yogurt at their breakfast meal for the duration of the intervention. Sixty-second sit-to-stand score improved by 31% in ES, with no change in Control (p < 0.01). Large effect sizes were observed for the difference in change scores between the groups for interpolated maximum leg pressing power (6% increase in ES) and thigh muscle cross-sectional area (2% increase in ES). The present pilot data suggest that exercise snacking might be a promising strategy to improve leg muscle function and size in older adults and that further investigation into zero-cost exercise strategies that allow high frequency of training is warranted.

Physiotherapy improves motor function in patients with the Parkinson variant of multiple system atrophy: A prospective trial

Background and objectivesGait impairment and reduced mobility are disabling symptoms of multiple system atrophy. While physiotherapy is increasingly recognized as a valuable supplement to pharmacotherapy for patients with Parkinson's disease, data on the efficacy of physiotherapy for multiple system atrophy are lacking. This study aimed to explore the feasibility of two consecutive exercise-based interventions in patients with multiple system atrophy. Subjects and MethodsWe included 10 patients with the parkinsonian variant of multiple system atrophy and 10 patients with Parkinson's disease, matched for gender and Hoehn & Yahr stage (≤3). Interventions consisted of a five-day inpatient physiotherapy program followed by a five-week unsupervised home-based exercise program. Outcomes included instrumented gait analysis, patient questionnaires, clinical rating scales and physical tests. Patients were examined at baseline, after the first inpatient treatment and again after the home-based intervention. Additionally, a structured telephone interview was performed immediately after the second intervention period. ResultsBoth patient groups exhibited a similar improvement of gait after the interventions, as measured by instrumented gait analysis. These effects reached their maximum level after inpatient physiotherapy and remained stable following the home-based exercise program. Patient questionnaires also showed improvements after the interventions, but motor clinical rating scales did not. ConclusionOur pilot results suggest that a short-term bout of physiotherapy is feasible, safe and improves gait performance in patients with multiple system atrophy. This highlights the potential of physiotherapy for this disabling condition where pharmacotherapy typically achieves poor effects. The present findings warrant a larger controlled study.

Telerehabilitation in Multiple Sclerosis: Results of a Randomized Feasibility and Efficacy Pilot Study.

A prospective, randomized, three-arm, evaluator blinded study to demonstrate the feasibility of a telerehabilitation (TR) program in individuals with ambulatory deficits secondary to Multiple Sclerosis (MS) and evaluate its efficacy when compared to conventional on-site physical therapy (PT) was completed. Thirty participants were evaluated at baseline and randomized to one of three groups with intervention lasting 8 weeks: Group 1 (control)- customized unsupervised home-based exercise program (HEP) 5 days a week; Group 2 (TR)- remote PT supervised via audio/visual real-time telecommunication twice weekly; Group 3 (PT)- in-person PT at the medical facility twice weekly. Outcomes included patient reported outcomes (PROs) obtained through questionnaires, and measurements of gait and balance performed with bedside tests and a computerized system. Functional gait assessment improved from baseline in all three groups. There were no significant differences between the TR and the conventional PT groups for a variety of outcome measures. TR is a feasible method to perform PT in persons with MS and has comparable efficacy to conventional in-person PT as measured by patient reported outcomes and objective outcomes of gait and balance.

Exercise induced effects on muscle function and range of motion in patients with hip osteoarthritis.

Patients with hip osteoarthritis have impairments in muscle function (muscle strength and power) and hip range of motion (ROM), and it is commonly believed that effective clinical management of osteoarthritis should address these impairments to reduce pain and disability. Therefore, the purpose of this study was to compare the short- and long-term effects of 4months of physiotherapist-supervised strength training, physiotherapist-supervised Nordic Walking (NW), or unsupervised home-based exercise (HBE) on muscle function and hip ROM in patients diagnosed with hip osteoarthritis. Secondary outcome analyses from an observer-blinded three-armed parallel-design randomized controlled trial in 60+-year-old patients with clinical hip osteoarthritis (American College of Rheumatology criteria) who were not on a waiting list for hip replacement. One hundred and fifty-two patients were randomized to either 4months of physiotherapist-supervised, moderate, progressive, strength training (n=50), physiotherapist-supervised NW (n=50), or unsupervised HBE (n=52). Maximal isometric hip and thigh muscle strength and leg extensor power and active hip ROM were assessed at baseline 2, 4, and 12months. Intention-to-treat-analyses did not show any significant between-group differences for improvements in muscle strength and power or ROM at any time points. Short-term significant (p<.05) increases in muscle strength were present in the physiotherapist-supervised exercise groups and in the long-term for muscle power in the NW-group. All exercise modes resulted in significant increases of ROM but long-term improvements were only shown for NW and HBE. Four months of physiotherapist-supervised, progressive, moderate, and strength training was less effective than hypothesized for improving muscle strength and power in patients with hip osteoarthritis who are not awaiting hip replacement. Our results may indicate that in these patients, improvements in disability are not necessarily dependent on improvements in strength and power or ROM.

Effect of Wii Fit™ exercise therapy on gait parameters in ankle sprain patients: A randomized controlled trial

Ankle sprains are the most common sport related injuries. An alternative to physical therapy in the treatment of ankle sprains is home based exercise therapy.This study aims to compare the effectiveness of Wii Fit™ exercise therapy in ankle sprain patients on temporal-spatial and kinematic gait parameters with a) conventional therapy and b) a control group not receiving exercise therapy.Ninety patients were randomly assigned to a Wii Fit™, physical therapy or control group. Temporal-spatial and kinematic gait parameters were assessed at baseline, 6 weeks and 6 months follow-up.All groups improved gait speed, cadence and step length between baseline and 6-week follow-up (P<0.036). Single support time improved only in the Wii Fit™ group (P<0.001). Symmetry index of the single support time improved in the Wii Fit™ group and physical therapy group (P<0.048). No between-group differences were found for temporal-spatial gait parameters (P>0.050). Maximum plantar flexion improved in the physical therapy and control group between baseline and 6-week follow-up (P<0.035). However, none of the groups improved dorsiflexion (P>0.050).In conclusion, an unsupervised home-based 6-week Wii Fit™ exercise therapy can be applied in ankle sprain patients. However, it was not more effective compared to physical therapy or no exercise therapy at all.

P 083 - The effect of a bespoke home based physical activity intervention on markers of oxidative stress and markers of general health in older adults

Home-based unsupervised exercise training has been shown to improve health in older adults. Assessing adherence, especially using a self-report format, in unsupervised exercise interventions is problematic. The aim of this pilot study was to objectively assess the effect of an unsupervised home-based exercise intervention in community dwelling older adults. Markers of oxidative stress and measures of health were assessed, including cerebral hemodynamics and cognitive function. Physical activity was measured continuously using a wrist watch type accelerometer with optical heart rate monitoring. A secondary aim of the study was to test the feasibility of a wrist activity monitor as a tool to assess physical activity in this population. The intervention failed to increase the level of physical activity in all the participants, although changes were observed. No significant changes were observed in markers of oxidative stress or other measures of health in response to the exercise intervention. Progressive goals, based on adherence measurement, are potentially important for the success of an unsupervised exercise intervention. Wrist-based accelerometers may be useful tools for the assessment of physical activity in sedentary older adults, but further development of specialist software may be necessary.

The Effects of Unsupervised Home-based Exercise Upon Functional Capacity After 6 Months of Discharge From Cardiac Rehabilitation: A Retrospective Observational Study.

It remains unclear whether self-regulated exercise is sufficient to maintain the benefits acquired during formal cardiac rehabilitation (CR). This retrospective observational study investigated the effects of a home-based exercise intervention after discharge from CR upon anthropometric and aerobic capacity markers in clinically stable patients. Fifty patients with cardiovascular disease were discharged after 6 months of CR and encouraged to maintain aerobic exercise without supervision. Subsequent to 6 months of follow-up, patients were assigned to compliant (n = 34) or noncompliant (n = 16) groups according to their compliance to the home-based program. Maximal aerobic capacity (VO2peak) and anthropometric data were assessed before CR, at discharge, and after 6 months of follow-up. No statistical differences between compliant and noncompliant groups were observed at baseline and at discharge from CR. At the end of the follow-up, statistical differences across groups were not found for body mass or body mass index, but increases in VO2peak (+3.6 vs. -0.6 ml/kg·min, P = 0.004) and oxygen pulse (+1.5 vs. +0.2 ml/bpm, P = .03) were greater in compliant than noncompliant group. Self-regulated exercising following CR discharge seems to be effective to maintain gains in exercise capacity acquired during supervised center-based programs.

In hip osteoarthritis, Nordic Walking is superior to strength training and home-based exercise for improving function.

This observer-blinded, randomized controlled trial compared the short- and long-term effects of 4months of supervised strength training (ST) in a local fitness center, supervised Nordic Walking (NW) in a local park, and unsupervised home-based exercise (HBE, control) on functional performance in 60+-year-old persons (n=152) with hip osteoarthritis (OA) not awaiting hip replacement. Functional performance [i.e., 30-s chair stand test (primary outcome), timed stair climbing, and 6-min walk test] and self-reported outcomes (i.e., physical function, pain, physical activity level, self-efficacy, and health-related quality of life) were measured at baseline and at 2, 4, and 12 months. Based on intention-to-treat-analyses improvements [mean (95% CI)] after intervention in number of chair stands were equal in all three groups at 4 months [ST: 0.9 (0.2-1.6), NW: 1.9 (0.8-3.0), HBE: 1.1 (0.1-2.0)] but greater in the NW group [1.4 (0.02-2.8)] than in the ST group at 12 months. Generally, improvements in functional performance were greater (P<0.001-P<0.03) after NW compared with HBE and ST at all follow-up time points. Furthermore, NW was superior (P<0.01) to HBE for improving vigorous physical activity and to both ST and HBE for improving (P<0.01) mental health. These data suggest that NW is the recommended exercise modality compared with ST and HBE.

Effect of early supervised progressive resistance training compared to unsupervised home-based exercise after fast-track total hip replacement applied to patients with preoperative functional limitations. A single-blinded randomised controlled trial

To examine if 2 weekly sessions of supervised progressive resistance training (PRT) in combination with 5 weekly sessions of unsupervised home-based exercise is more effective than 7 weekly sessions of unsupervised home-based exercise in improving leg-extension power of the operated leg 10 weeks after total hip replacement (THR) in patients with lower pre-operative function. A total of 73 patients scheduled for THR were randomised (1:1) to intervention group (IG, home based exercise 5 days/week and PRT 2 days/week) or control group (CG, home based exercise 7 days/week). The primary endpoint was change in leg extension power at 10 week follow up. Secondary outcomes were isometric hip muscle strength, sit-to-stand test, stair climb test, 20 m walking speed and patient-reported outcome (HOOS). Sixty-two completed the trial (85%). Leg extension power increased from baseline to the 10 week follow up in both groups; mean [95% CI] IG: 0.29 [0.13; 0.45] and CG: 0.26 [0.10; 0.42] W/kg, with no between-group difference (primary outcome) (P = 0.79). Maximal walking speed (P = 0.008) and stair climb performance (P = 0.04) improved more in the IG compared to CG, no other between-group differences existed. In this trial, supervised PRT twice a week in addition to 5 weekly sessions of unsupervised exercise for 10 weeks was not superior to 7 weekly sessions of unsupervised home-based exercise for 10 weeks in improving the primary outcome, leg-extension power of the operated leg, at the primary endpoint 10 weeks after surgery in THR patients with lower pre-operative function.

A systematic review of measures of self-reported adherence to unsupervised home-based rehabilitation exercise programmes, and their psychometric properties

BackgroundAdherence is an important factor contributing to the effectiveness of exercise-based rehabilitation. However, there appears to be a lack of reliable, validated measures to assess self-reported adherence to prescribed but...
