A trial to determine the reliability of the Supination Resistance Arch Blocks test for practitioners with varying levels of clinical experience.

Supination Resistance Arch Blocks Test The participant is told to march on the spot before standing in relaxed calcaneal stance position (RCSP). The tester will perform the Supination Resistance Arch Blocks test as outlined: 1.Place the first ‘block’ attached with an overlying valgus pad underneath the marked navicular tuberosity of each foot. 2. Add additional blocks under the first block until the Neutral Calcaneal Stance Position (NCSP) of the foot is achieved. This is confirmed by using a tractograph to measure the angle between the posterior calcaneal bisection and a line that is perpendicular to the ground. 3. If the NCSP is not achieved, continue adding blocks until the NCSP is achieved. 4. Record the number of blocks required to correct the foot from RCSP to NCSP and the NCSP value of the foot after correction. The Supination Resistance Arch Blocks test will be performed on both feet of each participant and will take approximately 15 minutes. The test will then be repeated on each foot after a one hour interval by the same tester. Upon completion of the test, the participants will be immediately followed up on their level of satisfaction and any adverse events they may have experienced during the study.
