This study examined the possible effects of radiotherapy on lower extremity muscle strength in patients with pelvic bone metastases. Ten male patients aged 40-60 years with pelvic bone metastases applied to participate in this study voluntarily. The muscle strength of these patients was measured with an isokinetic dynamometer device twice, before and after radiotherapy. The present study was carried out on ten patients with pelvic bone metastases. The analysis of the data obtained from the research was made in the SPSS 26.0 (SPSS, Inc., Chicago, IL, USA) program. No statistically significant difference was observed in the comparison of the knee flexion and knee extension peak torque values before and after radiotherapy, regardless of the right and left legs [knee flexion peak torque: F(1,14)= 2.986, p=.106, partial eta squared: .176; knee extension peak torque: F(1,14)= 3.426, p=.085, partial eta squared: .197]. According to the Bonferroni test, although there was no significant difference, it was determined that the participants' right and left leg peak torque values increased after radiotherapy application. It was determined that radiotherapy application positively affected muscle strength in patients with bone metastases. Especially in these populations, repeating such studies by increasing the sample size may contribute to planning training programs targeting strength development.
