Chronic ankle instability usually develops following an ankle sprain that has not adequately healed or was not rehabilitated completely. When you sprain your ankle, the connective tissues (ligaments) are stretched or torn. The ability to balance is often affected. Proper rehabilitation is needed to strengthen the muscles around the ankle and “retrain” the tissues within the ankle that affect balance. Failure to do so may result in repeated ankle sprains.
Repeated ankle sprains often cause – and perpetuate – chronic ankle instability. Each subsequent sprain leads to further weakening (or stretching) of the ligaments, resulting in greater instability and the likelihood of developing additional problems in the ankle
Overuse and stress on the heel bone through participation in sports is a major cause of calcaneal apophysitis. The heel’s growth plate is sensitive to repeated running and pounding on hard surfaces, resulting in muscle strain and inflamed tissue. For this reason, children and adolescents involved in soccer, track, or basketball are especially vulnerable.
Other potential causes of calcaneal apophysitis include obesity, a tight Achilles tendon, and biomechanical problems such as flatfoot or a high-arched foot.
There are two different categories of heel pain.
The First Is caused by over-use repetitive stress which refers to a soreness resulting from too much impact on a specific area of the foot. This condition, often referred to as "heel pain syndrome," can be caused by shoes with heels that are too low, a thinned out fat pad in the heel area, or from a sudden increase in activity.
The second is Plantar fasciitis, a very common diagnosis of heel pain, is usually caused from a biomechancial problem, such as over-pronation (flat feet).
The plantar fascia is a broad band of fibrous tissue that runs along the bottom surface of the foot, from the heel through the midfoot and into the forefoot.
Over-pronation can cause the plantar fascia to be excessively stretched and inflamed, resulting in pain in the heel and arch areas of the foot. Often the pain will be most intense first thing in the morning or after a prolonged period of rest.
The pain will gradually subside as the day progresses.
What is Ankle Instability
Ankle instability is a condition characterized by a recurring “giving way” of the outer (lateral) side of the ankle.
This condition often develops after repeated ankle sprains. Usually the “giving way” occurs while walking or doing other activities, but it can also happen when you’re just standing.
Many athletes, as well as others, suffer from chronic ankle instability.
