A comparison of rearfoot motion control and comfort between custom and semicustom foot orthotic devices.

Background: Motion control and comfort are primary objectives in orthotic intervention. Semicustom orthotic devices have been presented as a more cost-effective solution than custom orthotic devices. However, no studies have compared their function or comfort to that of custom orthotic devices.

Lower extremity joint coupling during running: a current update.

Background: The relationship between lower extremity mechanics and injury is not well understood. However, joint coupling studies are beginning to emerge, which may lend further insight into running biomechanics.

Purpose: To provide a current review of the research examining lower extremity joint coupling in running.
