The L-shaped probe, designed specifically for skin assessment, maybe useful for evaluating caesarean section (C-section) scars. However, reliability data for MyotonPRO measurements of C-section scars with this probe are limited. This study aimed to evaluate the inter-rater and intra-rater reliability of measuring the mechanical properties of C-section scar skin using the MyotonPRO with the L-shaped probe.  \nMaterials and Methods: Twenty-five women (23–42 years) with C-section scars were examined. Two raters conducted themyotonometric assessments over two consecutive days. Measurements were taken with the participant supine, using the L-shaped probe at six points around the scar (three above, three below; positioned at the scar’s endpoints and centre), each tested in three directions (right, left and upward/downward). Reliability was analysed using the intraclass correlation coefficient (ICC) with 95% confidence intervals (CIs), the standard error of measurement (SEM), minimal detectable change (MDC), coefficient of variation (CV) and Bland–Altman plots.  \nResults: Inter-rater reliability was good to excellent (ICC = 0.75–0.90), while intra-rater reliability was moderate to good, with slightly lower ICCs for consecutive-day measurements. SEM, MDC and CV values supported these findings, showing lower measurement error and narrower variability ranges between raters than within repeated measurements by the same rater. Conclusion: The MyotonPRO with the L-shaped probe provides reliable inter-and intra-rater measurements of C-section scar skin mechanical properties, making it a valuable tool for scar evaluation.  \n1  Introduction  \nMyotonometry is a relatively novel, easy to perform and noninvasive method to characterise the mechanical properties of superficial soft tissues [1] . It involves the application of an  \nexternal, brief(15 ms), low-intensity (0.58 N) mechanical impulse applied to the skin. The oscillatory tissue response allows for the immediate assessment of tension, stiffness and elasticity, among other parameters [2]. To date, myotonometry especially has been used to evaluate the mechanical properties of muscles [3–5],  \nThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.  \n© 2026 The Author(s).
