Effect of Preoperative Home-Based Exercise Training on Quality of Life After Lung Cancer Surgery: A Multicenter Randomized Controlled Trial.

BACKGROUND: Preoperative exercise training is recommended for improvement of clinical outcomes after lung cancer (LC) surgery. However, its effectiveness in preventing postoperative decline in quality of life (QoL) remains unknown. This study investigated the effect of preoperative home-based exercise training (PHET) on QoL after LC surgery. METHODS: Patients awaiting LC resection were randomized to PHET or a control group (CG). The PHET program combined aerobic and resistance exercise, with weekly telephone supervision. Primary outcome was QoL-assessed with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) at baseline, before surgery, and 1 month after surgery. The secondary outcomes were hospital length of stay and physical performance. The main analysis included a factorial repeated-measures analysis of variance. Additionally, the proportion of patients experiencing clinical deterioration from baseline to post-surgery was assessed. RESULTS: The study included 41 patients (68.1 ± 9.3 years; 68.3% male) in the intention-to-treat analysis (20 PHET patients, 21 CG patients). A significant group × time interaction was observed for global QoL (p = 0.004). Between-group differences in global QoL were statistically and clinically significant before surgery (mean difference [MD], 13.5 points; 95% confidence interval [CI], 2.4-24.6; p = 0.019) and after surgery (MD, 12.4 points; 95% CI, 1.3-23.4; p = 0.029), favoring PHET. Clinical deterioration of global QoL was reported by 71.4% of the CG patients compared with 30 % of the PHET patients (p = 0.003). Between-group differences in favor of PHET were found in pain and appetite loss as well as in physical, emotional and role functions after surgery (p < 0.05). Compared with CG, PHET was superior in improving preoperative five-times sit-to-stand and postoperative exercise capacity (p < 0.05). No between-group differences in other secondary outcomes were observed. CONCLUSION: The study showed that PHET can effectively prevent the decline in QoL after LC surgery.

[Efficacy of Home-Based Exercise Training and Adherence to Therapy in Patients After Coronary Artery Bypass Grafting].

AIM: to assess efficacy of home-based exercise training (HBET) at outpatient stage of cardiac rehabilitation and its impact on adherence to treatment in patients after coronary artery bypass grafting (CABG). MATERIAL AND METHODS: In 1 month after CABG 112 male patients (after completion of rehabilitation program in the sanatorium) were distributed to 3 groups with comparable demographic, clinical, and functional parameters: group 1 - patients fulfilling supervised cycling training program (SCTP), group 2 - patients subjected to home-based exercise training (HBET) with defined walking sessions (WS), and the control group of usual care without exercise training. Patients were examined 1, 4 months and 1 year after CABG. RESULTS: Three months SCTP was most efficient relative to improvement of exercise tolerance (ET), modification of cardiovascular risk factors (smoking, obesity, dyslipidemia), and of adherence to medical therapy. Lowest ET and worst adherence to medical and non-medical therapies were found in the group of usual care without exercise training. The intermediate position was occupied by patients subjected to HBET and WS. Effects of 3 months of HBET diminished by 1 year of follow-up. CONCLUSION: HBET of moderate intensity appeared to be safe, easily workable and affordable training program for patients after CABG. However, it was less effective, compared with SCTP. Moreover, effects of this rehabilitation program were transitory.

[The comparative analysis of the influence of the supervised exercise training and home-based exercise training on the psychological status of the following coronary artery bypass grafting].

This article was designed to report the results of the comparative analysis of the influence of the home-based exercise training (HBT) and the supervised exercise training in the form of the controlled training (CVT) under conditions of outpatient rehabilitative treatment on the patients' quality of life (QoL) and psychological status (including manifestations of anxiety and depression) following coronary artery bypass grafting (CABG). AIM: The objective of the present study was to evaluate the consequences of the application of different programs of physical rehabilitation under the outpatient conditions on the psychoemotional status and quality of life of the patients who had undergone coronary artery bypass grafting. MATERIALS AND METHODS: A total of 114 male patients suffering from coronary artery disease (CAD) who had undergone CABG were available for the examination. All the patients were allocated to three groups. Group 1 was comprised of the patients (n=36) treated with the use of the supervised cycling training (SCT) while group 2 consisted of the patients who had to perform home-based walking training (HBWT) (n=36). The group of comparison included 42 patients. The psychophysiological assessment was carried out based on the Beck Depression Inventory (BDI) and the Spielberger-Hanin Personal and Reactive Anxiety Scale. The quality of life (QoL) was assessed with the use of the SF-36 questionnaire. All the patients were examined prior to surgery, 1.4 months and 1 year after CABG. RESULTS: The study has demonstrated the most pronounced improvement in the quality of life of the patients following the 3-month supervised cycling training after CABG that was manifested as the decrease of anxiety and depression. The minimal changes in the psychological and emotional status were documented in the absence of any exercise training integrated into the postoperative rehabilitation program. Only the moderate improvement of QoL was observed in the patients treated with the application of the 3-month home-based walking training program after CABG. The positive effects of the three-month exercise training were evened out within 1 year after its initiation. DISCUSSION: It has been shown that the effectiveness of HBT is somewhat lower than that of CVT in terms of the influence on the psychoemotional status of the patients following CABG. This finding is at variance with the results reported by the foreign authors and should provide a basis for the enhancement of the effectiveness of the post-CABG rehabilitation programs to be implemented under conditions of the medical facilities, their principal objective being the education of the patients in safe and efficient methods for the pots-surgical self-rehabilitation with the emphasis placed on the measures intended for the improvement of the approaches to monitoring the compliance of the patients with the prescribed recommendations and for increasing their motivation to observe as long as possible the advices given by the health care professionals. CONCLUSION: The home-based walking training of moderate intensity provides a safe, easy to perform, and readily available tool for a large number of patients who underwent coronary artery bypass grafting even though it is somewhat less effective than the supervised cycling training. The effects of both rehabilitation modalities are rather short-term.

Feasibility and efficacy of home-based neurofunctional exercise vs. resistance exercise programs for ambulatory disability of multiple sclerosis patients with cognitive impairment.

BACKGROUND: Ambulatory disability and cognitive impairment are common and co-occuring manifestations of multiple sclerosis (MS). Neurofunctional training is a specific intervention performed in realistic environments that may have beneficial effects on ambulatory disability in persons with MS who have cognitive impairment. This pilot sudy investigated the feasibility and efficacy of an eight-week home-based neurofunctional training (HBNFT) program vs. home-based resistance training (HBRT) on ambulatory performance in MS patients with cognitive impairment. METHODS: Thirty males/females with MS (age 18-50 years, Expanded Disability Status Scale (EDSS) score ≤ 6, and processing speed score ≤ 41.5 as a marker of cognitive impairment) were randomly assigned into HBNFT and HBRT groups. After one week (three sessions) of center-based, supervised training for learning the programs and maximizing safety, the participants completed eight weeks (three sessions per week) of the home-based training programs. The programs were supported through videos, brochures and Digital Video Discs (DVDs) provided during clinic visits (weeks 1 and 5). Ambulatory performance (tandem stance test; tandem walk test; timed up-and-go (TUG); six-minute walk test (6MWT), 10- meter walking test (10MWT); timed 25 foot walk test (T25FWT); five times sit to stand test (5TSTS); six spot step test (SSST); and hand grip) was measured before and after the exercise programs. Feasibility and acceptability of exercise programs was assessed after the eight-week period. RESULTS: HBNFT significantly improved tandem walk test (P = 0.018), SSST (P = 0.026), and 6MWT (P = 0.037) compared with HBRT. No significant changes or differences were observed in other outcomes (P ≥ 0.05). HBNFT was well tolerated and resulted in no adverse events, whereas there were reports of pain, muscle cramps, and extreme fatigue among HBRT participant. CONCLUSION: The current pilot study provided initial support for HBNFT as a safe and feasible approach for improving some aspects of ambulation in persons with MS who have cognitive impairment. Such a pilot study provides initial proof-of-concept data for the design and implementation of an appropriately-powered randomized controlled trial (RCT) of neuro-functional training vs. traditional resistance exercise in a larger sample of persons with MS who present with co-occurring impairments in mobility and cognition.

Effectiveness of a Long-term Home-Based Exercise Training Program in Patients With COPD After Pulmonary Rehabilitation: A Multicenter Randomized Controlled Trial.

BACKGROUND: Most patients with COPD do not maintain exercise training after pulmonary rehabilitation (PR). RESEARCH QUESTION: Does a 12-month home-based, minimal-equipment strength training program after PR have an effect on dyspnea, exercise capacity, and patient-reported outcomes in patients with COPD? STUDY DESIGN AND METHODS: In a parallel-arm multicenter study across four Swiss PR clinics, patients with COPD were allocated randomly (1:1 ratio) into an intervention group (IG; home-based strength training program) or control group (CG; usual care). The primary outcome was change in Chronic Respiratory Questionnaire (CRQ) dyspnea scale score from baseline to 12 months. Secondary outcomes were change in exercise capacity (1-min sit-to-stand-test [1MSTST], 6-min walk test [6MWT]), health-related quality of life, exacerbations, and symptoms. We assessed the IG's experience by interviews at study end. Main analyses were based on the intention-to-treat approach, and adjusted linear regression models were used. RESULTS: One hundred twenty-three patients with COPD (IG, n = 61; CG, n = 62) were randomized, 61 of whom were women and whose mean ± SD age was 66.8 ± 8.1 years and mean ± SD FEV1 was 39.3 ± 15.3% predicted. One hundred four participants completed 12 months of follow-up (IG, n= 53; CG, n= 51). Of the 53 IG participants, 37 participants (70%) conducted the training until study end. We found no difference in change in CRQ dyspnea scale score over 12 months (adjusted mean difference, 0.28; 95% CI, -0.23 to 0.80; P = .27). We found moderate evidence for a difference in 1MSTST repetitions favoring the IG (adjusted mean difference, 2.6; 95% CI, 0.22-5.03; P = .033), but no evidence for an effect in other outcomes. Seventy-nine percent of the IG reported positive effects that they attributed to the training. INTERPRETATION: The home exercise program had no effect on dyspnea, but improved 1MSTST performance and patient-perceived fitness. The supported program was well accepted by patients with COPD and may facilitate continued exercise training at home. TRIAL REGISTRY: ClinicalTrials.gov; No.: NCT03461887; URL: www.

Home-Based Exercise Training in Multiple Sclerosis: A Systematic Review with Implications for Future Research.

BACKGROUND: Substantial evidence supports the benefits of supervised exercise training (ET) in people with multiple sclerosis (MS). However, there are limitations such as transportation problems preventing physical activity for some people with MS. One opportunity for increasing physical activity participant in people with MS is home-based exercise training (HBET), yet we are unaware of a systematic review of HBET in people with MS. We undertook a systematic review for enhancing the knowledge about HBET in people with MS. METHODS: To identify eligible studies, we included the medical subject headings (MeSH) keywords including 'multiple sclerosis' OR 'MS' OR 'degenerative nerve disease' AND 'home-based exercise' OR 'home-based training' OR 'home-based balance training' OR 'home-based rehabilitation' OR 'physical telerehabilitation' OR 'home-based walking' OR 'home-based step training.' Studies were included in this review that examined the effect of HBET in people with MS, were written in English, and available in full-text. RESULTS: According to inclusion and exclusion criteria, 24 studies were judged eligible to be included in this systematic review. The results indicated that a total number of 10 studies had mainly implemented combined ET interventions. Balance and aerobic ET had been included in 5 studies. Three studies had further administered resistance ET interventions and one study had applied exergaming. Moreover, 13 studies had focused on the effects of ET on physical fitness, one article had reflected on the impact of ET on fatigue, and nine cases had included fatigue, quality of life, and fitness as outcome measures. CONCLUSIONS: Home-based ET, 2-7 times per week, is beneficial, feasible, and safe in people with MS. Nevertheless, there were notable limitations, including (a) adherence to interventions, which needs to be addressed in future studies, and (b) disability-related outcomes which should be considered in future HBET studies.

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.

BACKGROUND: 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. OBJECTIVE: 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. DATA SOURCES: PubMed, CINAHL, Medline, Google Scholar, and Scopus databases and reference lists of included investigations were searched. STUDY SELECTION: Thirteen randomized controlled trials (RCTs) of exercise training impact on balance and upper body strength with concurrent control groups were included in the analysis. RESULTS: 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). CONCLUSION: 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.
