Does orthotics use improve comfort, speed and injury rate during running? Preliminary analysis of a randomised control trial

Figure 1  Image of Aetrex L700 Speed Orthotics.

Figure 2  Participant flow, including randomised group assignment and any withdrawals.

Figure 3  Internal rotation of lower limb joints and opposing external rotation of the patella caused by overpronation during running, which can lead to injuries.

Figure 4 Working principle of orthotics. A: The correction of lower limb alignment by orthotics, by reducing overpronation; B: Compared to the lower limb misalignment present without orthotics, due to overpronation.
