Official title
Morphological and Mechanical Changes in the Achilles Tendon After the Application of INDIBA® Therapy in Healthy Runners: A Pre-post Quasi-experimental Study
Overview
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.
Detailed description
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.
Interventions
- Device 448 kHz capacitive resistive monopolar radiofrequency
The procedure will consist of a 20-minute radiofrequency session on the Achilles tendon, applying 10 minutes in capacitive mode and 10 minutes in resistive mode. The device has a maximum peak power of 200 W and 450 V. Both modes will be administered as a hyperthermia dose, adjusted according to the patient's subjective perception of heat, with a target of 8/10. The application will be performed longitudinally on the Achilles tendon, from proximal to distal and from distal to proximal, measuring
Primary outcome measures
- Achilles tendon thickness (mm) measured by B-mode ultrasound [Time frame: 1 hour]
- Elastography in Achilles tendon [Time frame: 1 hour]
Secondary outcome measures (2)
- Plantar flexion strength [Time frame: 1 hour]
- Functionality of the lower limb [Time frame: 1 hour]
