The effect orthoses have on altering gait and recovery from

lower limb sports injuries.

Mark Rule (0947944)

Implications• It is expected that the findings of the study may have a

bearing on which orthoses practitioners prescribe for runner’s injuries. This is because one type of orthoses may provide a quicker return to activity by reducing pain or injury quicker than the others due to the correct biomechanical alignment of the lower limb.

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?

Research Design

• Quantitative vs. Qualitative

Research Design - Sampling

• Sampling followed both the probability and nonprobability format. The nonprobability format involves including participants who have a specific trait, which in this case is runners with lower limb injuries. The probability format utilises simple random sampling as participants will need to be randomly split into three groups.

Research Design - Surveys• GRADE 1 STRAIN

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

• GRADE 2 STRAINExtensive 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 STRAINComplete rupture of a muscle. In a sports person this will usually require surgery to repair the muscle. The rehabilitation time is around 3 months.
