Define the term sprain.

A sprain is a stretch or tear of a ligament, the tissue that joins bone to bone at a joint. The ankle and the knee are common sites in sport.

Why does a basketball player often sprain the ligaments on the outside of the ankle?

Landing on another player's foot can turn the sole of the foot sharply inwards, a movement called inversion. The ligaments on the outer side of the ankle are overstretched or torn.

Describe how sprains are graded by severity.

A grade 1 sprain is a mild stretch with little loss of stability. A grade 2 sprain is a partial tear, and a grade 3 sprain is a complete rupture of the ligament.

Questions from this subtopic

Each one with the model answer underneath.

1
What is the difference between an acute injury and an overuse injury?
Model answer
An acute injury happens suddenly, from a single impact, fall or twist. An overuse injury develops gradually from repeated stress on the same tissue.
2
What is soft tissue damage, and how does it differ from hard tissue damage?
Model answer
Soft tissue damage affects muscle, tendon, ligament or skin, such as a bruise from a knee in the thigh. Hard tissue damage affects bone, as in a fracture.
3
How can the cause of an injury be classed as intrinsic or extrinsic?
Model answer
An intrinsic cause comes from within the performer, such as poor technique, muscle imbalance or fatigue. An extrinsic cause comes from outside, such as a tackle, a poor surface or faulty equipment.
4
Define the term sprain.
Model answer
A sprain is a stretch or tear of a ligament, the tissue that joins bone to bone at a joint. The ankle and the knee are common sites in sport.
5
Why does a basketball player often sprain the ligaments on the outside of the ankle?

Model answer
A grade 1 sprain is a mild stretch with little loss of stability. A grade 2 sprain is a partial tear, and a grade 3 sprain is a complete rupture of the ligament.
