What therapy method uses a self-contained unit with heated particles to treat body parts?

Fluidotherapy is a method that employs a self-contained unit filled with heated particles, typically made of fine cellulose material. The purpose of this therapy is to provide dry heat and facilitate thermal therapy for the treatment of various conditions. The heated particles circulate around the affected area, providing an even distribution of warmth while allowing for movement within the unit, making it beneficial for increasing blood flow, reducing pain, and improving joint mobility.

In contrast, ultrasound therapy utilizes sound waves to generate heat in deeper tissues, electrotherapy employs electrical stimulation for pain management and muscle reeducation, and hydrotherapy involves the use of water for treatments such as immersion or surface applications. Each of these methods has its unique properties and uses but does not utilize the heated particle medium that characterizes fluidotherapy.
