Hi Michelle and thank you for your interest.
The BFST and ColdCure are registered medical devices whereas the KB Basics are consumer grade.The Basics Heating wrap is a heating pad that contains an infrared heating element in order to soothe and relax the targeted area. The BFST (Blood Flow Stimulation Therapy) on the other hand, is a diathermic device designed to stimulate blood flow via Electro Magnetic Energy. The BFST is designed to heal soft tissue injuries.
In regards to Patellar Subluxation, the treatment itself will not prevent the knee cap/patella from sliding, but it will help heal the surrounding tendons and ligaments that have been affected (which is what typically causes the pain and discomfort).
If you have any further questions or concerns, please do not hesitate to contact us.
Kind regards,
Amber
