What is the forearm position during ULTT4?

During Upper Limb Tension Test 4 (ULTT4), the forearm is positioned in supination. This position is critical because it helps to differentiate and assess the various neural structures involved, particularly the ulnar nerve and its associated pathways. In ULTT4, the test is designed to assess the ulnar nerve by stretching it while the forearm is supinated, allowing for effective evaluation of any restrictions or symptoms related to ulnar nerve compromise.

Supination also aids in isolating the tension applied to the ulnar nerve and surrounding structures, making it easier to evoke symptoms or recognize movement restrictions that may indicate neural tension or compromise. This ensures a more specific assessment during the test, allowing clinicians to gather valuable information regarding potential ulnar nerve conditions. Other forearm positions, such as pronation or neutral, would not provide the same level of specificity for assessing ulnar nerve mobility and could lead to misleading results.
