Abstract: The present disclosure provides in a method of treating muscle soreness or soft tissue oedema. The method comprises frictionally engaging a contact member of an apparatus with skin portions of a patient. The contact member of the apparatus is arranged to perform a substantially planar orbital motion along the skin portions. The method further comprises applying the substantially planar orbital motion along the skin portions of the patient so that soft tissue adjacent the skin portion is locally moved in a corresponding manner.
