Of the Following Choices, Which Is the Most Appropriate Application

Of the following choices, which is the most appropriate application of the hold-relax (contract-relax) method of muscle inhibition and elongation of the gastrocnemius muscle? Extend the patient's knee, stabilize the lower leg, and:

A) Place the patient's ankle in as much dorsiflexion as is comfortable; have the patient isometrically contract the plantar flexors against resistance for 6 to 10 seconds.Then have the patient relax as you passively dorsiflex the ankle.
B) Place the patient's ankle in a fully plantar flexed position.Have the patient concentrically contract the dorsiflexors against your manual resistance through as much ROM as possible.
C) Place the patient's ankle in as much dorsiflexion as possible; have the patient isometrically contract the dorsiflexors against resistance for 6 to 10 seconds.Then have the patient relax as you passively dorsiflex the ankle.
D) Place the patient's ankle in a comfortably dorsiflexed position; have the patient concentrically contract the plantar flexors against your resistance through the available ROM.Then have the patient dorsiflex the ankle as far as possible.
