I am a physical therapist and have been practicing for 42 years. My patient load is orthopedics and sports injuries with a wide age variation. I think being cautious about who you use the bands on is smart. I like to show the patient what I’m going to do on the non-involved side first. I will use less pressure if the patient is not comfortable with the technique. The response to the technique and how well I can explain it is important. I have used it on total knee and ACL’s, if the soft tissue is the problem. Also consider the age of the client and their vascular condition of the extremity. I do a lot of soft tissue work with my hands before I do bands. I can feel the soft tissue response to this work and usually gives a good basis for continued deep work if necessary.
Hope this helps.
