A schematic diagram of the 30° ROM through which the subjects attempted to exert maximal isometric, lengthening, and shortening actions of the plantar- and dorsiflexors. Angle-specific torque (strength) measures were made for all tests at an ankle angle of 90°—that is, as the ankle passed through 90° for the shortening and lengthening measures and statically at 90° for the isometric measures.

Angle-specific maximal voluntary torque (strength) measured at an ankle angle of 90° during isometric, shortening, and lengthening plantar- and dorsiflexor actions in children with JIA (n=10, black bars) and healthy, age- and gender-matched controls (n=10, white bars).
