Morphological and Mechanical Assessment in the Achilles Tendon After Radiofrequency Stimulation in Runners

Morphological and Mechanical Changes in the Achilles Tendon After the Application of INDIBA® Therapy in Healthy Runners: A Pre-post Quasi-experimental Study

448 kHz capacitive-resistive monopolar radiofrequency is an emerging physiotherapy technique whose usefulness and clinical relevance still need to be investigated. This study is a pre-post quasi-experimental study in which several variables will be measured before and immediately after 448 kHz capacitive resistive monopolar radiofrequency. It aims to analyze the morphological and mechanical changes in the Achilles tendon following the intervention in healthy runners.

The Achilles tendon is fundamental to running biomechanics, and its performance directly affects athletic performance and injury prevention. 448 kHz capacitive resistive monopolar radiofrequency has demonstrated effects on vascularization, recovery, and elasticity of musculoskeletal tissues. However, there are no studies that comprehensively evaluate the morphological, mechanical, and functional changes in the Achilles tendón in healthy runners after the application of this technique. The investigators expect the intervention to induce short-term morphological and mechanical changes in the Achilles tendon, providing further insight into the potential of this technique as a preventive tool.
