Ankle injuries are all too common for athletes and non athletes alike. Recovering from a sprain or worse can often take months. During this phase we cannot use our feet properly and may need to limp to avoid pain. Limping causes a person to walk abnormally, putting undue stress on many body parts and can lead to plantar fasciitis and other issues. The tennis ball technique is widely known to improve tightness in the foot, calf, lower and upper back. This is why so many doctors and physical therapists will recommend their patients to be diligent about maintaining proper foot function after an injury. Favoring one foot during an injury causes an imbalance in muscle use. Wearing AVOS directly after a foot/ankle sprain can help release added tension that may be affecting an injury. If an injury becomes more painful, do not use. Improving foot function and building strength are our best options to help lessen the chance that injury may occur.
