1. Passively move your partner’s foot into full eversion and full inversion. In which direction were you able to obtain more motion? What is the relationship of your finding to the asymmetry between the medial and lateral malleoli?

2. Test the strength of the gastrocnemius with the knee fully flexed and with the knee extended. Note the difference in the strength of contraction of the gastrocnemius with the knee fully flexed versus with the knee extended. What principle does this illustrate? What are the implications of this for manual muscle testing?

3. Place your partner’s limb in the most effective position to lengthen (stretch) the gastrocnemius. Explain.

4. Explain why it is important to strengthen the peroneus longus and brevis following an inversion ankle sprain.

5. If you measure ankle dorsiflexion with the knee extended and with the knee flexed would you find a difference in measurement between the two positions? If so, why?
