Dataset used for the study entitled: Assessment of Functional Asymmetry in Breast Cancer Survivors Using Inertial Devices

Abstract

Breast cancer (BC), despite its high survival rate, can lead to significant functional sequelae in the glenohumeral joint following surgical intervention. The present study explores the possible influence of the operated side on angular velocity during a lateral opening test, comparing the intervened arm with the non-operated arm, as a potential indicator of functional asymmetry. This is an observational study with a comparative cross-sectional design. The sample consisted of 22 women, with a mean age of 55.95 ± 6.34 years, who were BC survivors and had undergone surgery on only one arm. Angular velocity was recorded in both arms at 1000 Hz for 15 repetitions on an inclined bench with a 2 kg load, using the WIMU PRO™ inertial device. The results, analyzed using repeated measures ANOVA, showed a significant interaction between the evaluated arm and the operated side (p = 0.001), suggesting lower velocity in the affected arm. This difference could indicate the existence of postoperative functional asymmetries, which would have relevant implications for the prescription of individualized therapeutic exercise. The use of angular velocity as a complementary tool for functional assessment in rehabilitation programs for BC survivors is suggested.
