Which movement is NOT typically tested as part of ankle and foot ROM and strength assessment?

• A. Knee flexion
• B. Plantar flexion
• C. Dorsiflexion
• D. Inversion

Answer: (A)

Movements checked in ankle and foot assessment are those that move the ankle and foot joints themselves. Knee flexion is a motion of the knee joint and isn’t an ankle/foot movement, so it isn’t part of standard ankle and foot ROM testing. The usual ROM checks—plantarflexion (pointing the toes), dorsiflexion (lifting the foot upward), and inversion (turning the sole inward)—target the ankle and subtalar joints directly. Strength testing focuses on the muscles crossing these joints, like dorsiflexors, plantarflexors, invertors, and evertors. Note that while the gastrocnemius crosses both the knee and ankle and knee position can influence plantarflexion strength, the movement being measured remains at the ankle. Therefore knee flexion is not typically tested in this context.
