SLANT BOARD INVERSION RAIL

The slant board inversion regressive angular isometric loading exercise is used to improve end range ankle mobility. Start by propping your foot with a slant board so that the outer aspect of the foot is on the floor and the inner aspect is elevated on an incline with the slant board. Begin to contract the ankle inverters by attempting to raise the inner aspect of the foot off the slant board. Note that you may not be able to achieve any movement during this part of the exercise. Hold a maximum contraction for 4-8 seconds. Rest in a stretched position at a 1:1 work to rest ratio.
