Final answer:
In treating pronator teres syndrome, a Forearm Pronator Stretch is recommended to alleviate the pressure on the median nerve by stretching the pronator teres muscle, as this muscle's function is opposite to the action of supination of the forearm.
Step-by-step explanation:
When addressing pronator teres syndrome, a condition marked by the impingement of the median nerve by the tight pronator teres muscle, the appropriate stretch to prescribe would be a Forearm Pronator Stretch. This type of stretch is directed at lengthening the pronator muscles, thus alleviating the pressure on the median nerve.
The pronators involved in this condition are the pronator teres and the pronator quadratus. Supination, which involves turning the forearm anteriorly, helps stretch the pronator teres since the action of supination is opposite to pronation. Remember, when the forearm faces anteriorly it is in supination, and when it faces posteriorly it is in pronation. Therefore, an effective stretch for the pronator teres would involve the forearm's movement into supination, which is achieved by a Forearm Pronator Stretch.
To stretch the pronator teres muscle in pronator teres syndrome, you would perform a Forearm Pronator Stretch (D).
