ABSTRACT
Background: Postoperative recovery in lung cancer patients is a complex process, where breathing exercises may play a crucial role in enhancing pulmonary function and quality of life (QoL). This study systematically reviews and meta-analyzes the impact of breathing exercises on post-surgical lung function and QoL in lung cancer patients. Methods: An extensive literature search was conducted across PubMed, Cochrane, Web of Science, and Embase databases using terms like "Lung Neoplasms", "breathing exercises", and "randomized controlled trial", supplemented by Medical Subject Headings (MeSH) and free words. The Cochrane risk of bias tool was used for quality assessment. A systematic review and meta-analysis on the effects of breathing exercises post-lung cancer surgery followed by data extraction and quality evaluation. Results: From 384 retrieved studies, 10 met the inclusion criteria and were selected for detailed analysis. The main outcomes assessed were postoperative pulmonary function indices and QoL measures. The majority of studies were deemed 'low risk' for random sequence generation and allocation concealment. However, due to the nature of the interventions, blinding was a 'high risk' in most cases. The meta-analysis revealed significant improvements in key pulmonary function indices: forced vital capacity (FVC%) increased by an average of 1.73%, maximal voluntary ventilation (MVV) improved by 7.58 L/min, and maximal inspiratory pressure (MIP) enhanced by 0.95 cmH2O. Additionally, there was a notable alleviation of postoperative dyspnea and an enhancement in QoL, with anxiety scores decreasing by an average of 3.42 points and complication rates reducing correspondingly. However, the interventions did not significantly affect physical activity levels or performance on the 6-minute walk test (6WMT), with effect sizes for these outcomes being non-significant. Conclusions: This study indicates that breathing exercises significantly improve postoperative pulmonary function and QoL in lung cancer patients. Future research should delve into the mechanisms behind these exercises and evaluate their long-term rehabilitation effects. Customized programs could further optimize recovery and enhance patient QoL.
ABSTRACT
OBJECTIVE: Understanding the characteristics related to cardiorespiratory fitness after stroke can provide reference values for patients in clinical rehabilitation exercise. This meta- analysis aimed to investigate the effect of robot-assisted gait training in improving cardiorespiratory fitness in post-stroke patients, compared to conventional rehabilitation training. METHODS: PubMed, EMBASE, Web of Science, Cochrane Database of Systematic Reviews, CBM, CNKI and Wanfang databases were searched until March 18th, 2024. Randomized controlled trials (RCTs) comparing the effectiveness of robot-assisted gait training versus control group were included. The main outcome variable was peak oxygen uptake. 6-minute walking test, peak heart rate, peak inspiratory expiratory ratio as our secondary indicators. RevMan 5.3 software was used for statistical analysis. RESULTS: A total of 17 articles were included, involving 689 subjects. The results showed a significant effect for robot-assisted gait training to improve VO2peak (MD = 1.85; 95% CI: -0.13 to 3.57; p = 0.04) and 6WMT (MD = 19.26; 95% CI: 10.43 to 28.08; p < 0.0001). However, no significant difference favouring robot-assisted gait training were found in HRpeak (MD = 3.56; 95% CI: -1.90 to 9.02; p = 0.20) and RERpeak (MD = -0.01; 95% CI: -0.04 to 0.01; p = 0.34). CONCLUSION: These results showed that robot-assisted gait training may have a beneficial effect in improving VO2peak and 6WMT, with a moderate recommendation level according to the GRADE guidelines.

Introduction: Chronic lower back pain (cLBP), frequently attributed to lumbar disk herniation (LDH), imposes substantial limitations on daily activities. Despite its prevalence, the neural mechanisms underlying lower back pain remain incompletely elucidated. Functional magnetic resonance imaging (fMRI) emerges as a non-invasive modality extensively employed for investigating neuroplastic changes in neuroscience. In this study, task-based and resting-state fMRI methodologies are employed to probe the central mechanisms of lower back pain. Methods: The study included 71 chronic lower back pain patients (cLBP group) due to LDH and 80 age, gender, and education-matched healthy volunteers (HC group). The subjects are mainly middle-aged and elderly individuals. Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Japanese Orthopedic Association Scores (JOA) were recorded. Resting-state and task-based fMRI data were collected. Results/discussion: No significant differences were observed in age, gender, and education level between the two groups. In the cLBP group during task execution, there was diffuse and reduced activation observed in the primary motor cortex and supplementary motor area. Additionally, during resting states, notable changes were detected in brain regions, particularly in the frontal lobe, primary sensory area, primary motor cortex, precuneus, and caudate nucleus, accompanied by alterations in Amplitude of Low Frequency Fluctuation, Regional Homogeneity, Degree Centrality, and functional connectivity. These findings suggest that chronic lower back pain may entail reduced excitability in sensory-motor areas during tasks and heightened activity in the sensory-motor network during resting states, along with modified functional connectivity in various brain regions.
