IN COLLABORATION WITH
Ankle sprains are caused by direct or indirect trauma to the ankle ligaments. In a sprain, the ankle ligaments that normally support the ankle are either stretched beyond their normal limits or torn outright as a result of this trauma.
The sprain can occur when the ankle is forced beyond its normal range of motion, such as when people twist their ankle when making a sudden stop on an athletic field or track, walking or running on an uneven surface, or when tripping over an obstacle. If not treated, or with repeated sprains of the same tissues, pain and dysfunction from acute ankle sprains can become chronic.
The complex design of an ankle makes it a relatively stable joint compared to other joints in the body, and this stability is essential to its function.
The ankle sustains 1.5 times of the body's weight in impact with every walking step, and up to 8 times the body's weight with each step when running or jumping. In high-impact activities, the normally stable ankle is subject to increased injury risk, especially when it turns or twists too far out of its normal range of motion.
ANKLE INJURIES COMMONLY OCCUR DURING
Acute injury that forces the ankle joint beyond its normal range of motion, such as in a sports injury or falling off.
Overuse injury caused by repetitive forces, such as repeated hard landings involved in sports such as long distance running and basketball.
LIGAMENTS OF THE ANKLE
3 ligaments on the outside of the ankle make up the lateral ligament complex.
Anterior talofibular ligament (ATFL)
Calcaneofibular ligament (CFL)
Posterior talofibular ligament (PTFL
Deltoid ligament - a thick ligament which supports the entire medial, or inner side of the ankle
The anterior inferior Tibiofibular ligament (AITFL), which connects the tibia to the fibula
Two posterior fibular ligaments, which crisscross the back of the tibia and fibula:
Posterior inferior Tibiofibular ligament (PITFL)
ANKLE SPRAIN SEVERITY GRADING
Physiotherapy is the primary part in ankle rehabilitation to regain optimal ankle strength and performance. Ankle rehab programs begin with non-weight bearing ankle motion exercises.
Increase reps as you get stronger for progression.
