Radiofrequency in Patients Post Covid 19 With Respiratory Sequelae.

The sequelae that occur in post-COVID-19 patients are multiple and, at a therapeutic level, these represent a new challenge within the general context of the pandemic that the world is suffering. The virus has managed to end thousands of lives today and many other cases are being charged as directly responsible for a multiplicity of multisystem damages that need to be diagnosed and treated. Among the most relevant, are those that can affect to respiratory levels in patients without previous pahologies, and in patients at risk who already had a pathology prior to infection. On the other hand, signs and symptoms have been observed characteristic in the organ systems described above in post-contagion patients, directly associated with sequelae SARV-CoV2. The radiofrequency (RF) of electromagnetic waves represents a technology of proven efficacy and safety in multiple fields of both human and veterinary medicine. These include neurological pathologies, respiratory disease and very especially those that affect the locomotor system. In therapeutics there are different RF modalities depending on the modality, polarity, type of signal and frequency, which in turn translate into different therapeutic profiles, clinical indications, efficacy and safety. Among the RF technologies most used today and that have a greater scientific background, is the one known as Resistive Capacitive Monopolar RadioFrequency at 448 kHz (INDIBA®) (RFMCR). This study aims to assess the efficacy and safety of RFMCR in the treatment of respiratory sequelae in patients presenting this type of pathologies that appear after contagion by COVID-19. Through this non-invasive technique, the investigators want to show that RF can help the physical rehabilitation of these patients through metabolic stimulation, increased vascularization and oxygenation of directly affected tissues, effects of deep hyperthermia generated by the interaction of the current with the treated biological substrate, as well as t
