A strap tension indicator for orthopedic brace is provided. Certain embodiments include a strap tab cap that is slidable relative to a rigid brace frame member. As tension in the strap increases or decreases, the strap tab cap slides with respect to the frame member, covering and uncovering various indicator portions on the frame member. Certain other embodiments include a strap tab that is slidable relative to a strap tab cap. As tension in the strap increases or decreases, the strap tab slides relative to the strap tab cap, covering and uncovering various indicator portions on the strap tab and/or the frame member. The strap tension indicator provides positive indication of optimal strap tension. Certain embodiments also provide positive indication of inadequate or excessive strap tension.
