The ARP Wave helped to fire my muscles to work better and harder. There has been a drastic improvement in my ability to perform jobs in the kitchen, garden, and self care (dressing, hair care, reaching, caring, and using utensils). The quality of care stands out to me. Dr. Darr spends an adequate amount of time with patients, but the quality of that time is more important. He takes time to answer all your questions. I would say to anyone that he is the best or one of the best in his fields.
