Which condition is a contraindication for Elevating Leg Rests?

• A. Knee flexor spasticity
• B. Knee extensor spasticity
• C. Ankle plantarflexion contracture
• D. Severe hip abduction limitation

Answer: (A)

Elevating leg rests position the leg with the knee in an extended or lengthened state to raise the limb. If the knee flexors (hamstrings) are spastic, they are abnormally tight and resist being lengthened. Forcing the knee into extension against this increased tone triggers a stretch reflex, raises spasticity, and can cause discomfort or injury, so elevating leg rests are contraindicated when knee flexor spasticity is present.

The other conditions don’t create the same direct issue: extensor spasticity involves maintaining extension rather than resisting a stretch in the knee, ankle plantarflexion contracture mainly affects the ankle alignment, and severe hip abduction limitation primarily complicates positioning fit rather than the knee’s response to an elevated rest.
