Reliability of Myoton in Evaluating Skin Biomechanics in Breast Cancer-Related Lymphedema

This study aims to evaluate the intra- and inter-rater reliability of the MyotonPRO, a handheld device that measures the viscoelastic properties of the skin, in patients with breast cancer-related lymphedema. Twenty women with unilateral upper extremity lymphedema will be included. Each participant will undergo repeated skin assessments using the MyotonPRO by two independent raters. Additionally, ultrasonographic tissue characteristics and limb volume measurements will be performed. The findings are expected to contribute to the validation of the MyotonPRO for use in clinical lymphedema evaluation.
