What is Gait?

Runners gait

Injury

What is an orthotic?

• Device to correct a patients physical posture and function.

• Serve to maximise function and mobility, minimize pain, and prevent the progression of a physical abnormality.

Research Question

What is the best orthotic treatment in order to help runners recover

quicker from injury?

GRADE 1 STRA

IN

•Damage to individual muscle fibres (less than 5% of fibres). This is a mild strain which requires 2 to 3 weeks rest.

GRADE 2 STRA

IN

•Extensive damage, with more muscle fibres involved, but the muscle is not completely ruptured. The rest period required is usually between 3 and 6 weeks.

GRADE 3 STRA

IN.

•Complete rupture of a muscle. In a sports person this will usually require surgery to repair the muscle. The rehabilitation time is around 3 months.
