Abstract

Background: Breast cancer and chemotherapy can reduce muscle strength through systemic and neuromusculoskeletal effects. This study aimed to evaluate the effect of low-intensity cycle ergometer exercise on quadriceps femoris strength in patients receiving chemotherapy. Methods: A randomized controlled trial was conducted at the medical rehabilitation outpatient clinic, Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, from May to November 2024. Twenty female patients aged 18–59 years with stage II–III breast cancer who had completed at least three chemotherapy cycles were enrolled. Eligible participants had normal echocardiography findings (left ventricular ejection fraction ≥ 50%) and oncologist approval. Exclusion criteria included hemodynamic instability, hematologic abnormalities, arrhythmia, pulmonary disease exacerbations, recent surgery or radiotherapy, severe pain, or cognitive disorders. Participants were randomly assigned to either an intervention group or a control group. The intervention group performed low-intensity cycle ergometer training twice weekly for eight, while the control group performed breathing exercises only. Quadriceps femoris strength was measured before and after the intervention using a handheld dynamometer. Data were analyzed using paired and independent t-tests, with significance set at p-value < 0.05. Results: After eight weeks, the intervention group showed significantly greater increases in quadriceps femoris strength compared with the control group (right leg: p = 0.006; left leg: p= 0.020). Mean strength gains were 4.38 ± 2.3 kg (right) and 3.22 ± 1.9 kg (left), whereas the control group showed significant declines. Large effect sizes (Cohen’s d > 1) indicated clinically meaningful improvements in the exercise group. Conclusion: The intervention group showed significantly greater preservation and improvement of quadriceps femoris strength than the control group. Low-intensity cycle ergometer exercise appears to be a safe and effective rehabilitation strategy for maintaining muscle strength, functional capacity, and quality of life in breast cancer patients undergoing chemotherapy.

Abstract

Introduction: Studies showed that the condition of joint hypermobility is quite common in children. In general, joint hypermobility asses through the Beighton score method. The objective of this research was to investigate the relationship between beighton score and walking age in children.Method: This research was conducted at a kindergarten in Surabaya using an observational analytic research type and a cross-sectional design. Data collected through interviews and physical examinations. A joint hypermobility examination performed using the Beighton score criteria. Meanwhile data was analyzed using the crosstabulation and Spearman test.Result: It was found that 84% of children had ≥4/9 score on the Beighton score and there were 92% with positive Beighton score in the knee joint. In this study, as many as 20 children experienced the first independent walks over 18 months when 18 of them who has Beighton score ≥4 points. However, there is no correlation found on the Beighton score and the walking age [sig. (2-tailed) = 0.053].Conclusion: Children who have ≥4 points of Beighton score are mostly found in this study. The relationship between the Beighton score and walking age was not statistically significant.
