Ask a PT Response: "For my patients who have sustained ankle sprains, range of motion exercises are commonly initiated in the beginning stages of rehab. These range of motion exercises can involve dorsiflexion and plantarflexion (up/down of foot) and ankle eversion and inversion (in/out of foot). Instruction is given to my patients to perform exercises to tolerance and to limit ankle inversion range of motion. The reason for caution with inversion is that most ankle sprains are inversion ankle sprains. The ligaments at the outside of the ankle are usually injured with an inversion sprain and caution should be taken to prevent further irritation or injury. If you are experiencing a tearing sensation with range of motion it may be a good idea to seek out medical attention to make sure you have not torn any ligaments or tendons. Meanwhile following the PRICE principle (protect, rest, ice, compress, elevate) would also be recommended, as well as the utlization of an Ankle Stabilizing Orthosis (ASO) to assist with stability and support with weight bearing activities. Individuals who have sustained grade I or II sprains can require anywhere from 3+ wks to fully recover, while a grade III sprain will most likely require a much longer time time for recovery along with other medical interventions. Should your condition at your ankles continue to persist ovr time, I would definitely recommend you seek the attention of a physical therapist or orthopedic MD. I wish you the best of luck with your recovery."
