Physiotherapist, natural health practitioner (physiotherapy)
Specialist in manual therapy and craniofacial therapy (CRAFTA)
For more than 10 years Margarita has often treated people in her practice who also suffer from pain when cycling. The contact with ergotec came about through the printed version of RichtigRadfahren.de, which she gave to affected patients in her practice as part of their treatment.
In the course of her treatment of cyclists with pain syndromes (neck, shoulder and arm pain as well as knee, hip, foot and back complaints), Margarita has often found that the symptoms can frequently be traced back to an incorrect seating position when cycling, especially on longer rides. In addition to the incorrect seating position, the cause can also lie in the selection of incorrect components.
Margarita says: "We base our treatment on the complaints, functional or activity restrictions that become visible in our findings. We not only look at the specific region of your complaints, but at the whole body. The aim of our treatment is to promote your independence and self-reliance as a patient and to activate the self-healing powers of the organism."To the website
