External Ankle Supports - 3D Motion Analysis

Untreated ankle sprains often remain symptomatic and may end in chronic instability. The aim of our study is to quantify the stabilizing effect of different devices. Through the use of a foot measurement model in 3D motion analysis the influence of the devices with respect to a mechanical effect is examined by means of different tests. The dynamic postural control is quantified. The hypothesis was that the devices would stabilize differently the foot segments.

Inclusion Criteria:

• chronic ankle instability
• "giving way"
• repeated ankle sprains

Exclusion Criteria:

• other injuries of the lower extremities
• surgery on the lower extremities
