Hi Danny,
Haven't written in a while-my husband has just finished chemo and rad and was really rough. Anyway, he has the Therabite as well. We had our lymphedema physical therapist show us, but certainly the oral maxillofacial surgeons are familiar as well as physical medicine md's. Our PT was well versed-better to have someone show you and discuss settings and progression. You could always ask the prescribing doc.
Good Luck

Caregiver to husband Lee-Stage IV SCC base of tongue/epiglottis. Had total glossectomy/partial laryngectomy/ radical neck dissec 4/05 followed by chemo and rad.
