The provided references do not fully explain how to elicit the triceps reflex; however, we can infer some principles from the demonstration of the Achilles reflex that apply to deep tendon reflexes in general. To perform the triceps reflex, you need to appropriately position the patient, apply slight tension to the triceps muscle, and then strike the triceps tendon.
Steps for Eliciting the Triceps Reflex
While specific details for the triceps reflex were not provided, the following steps outline a general approach to eliciting deep tendon reflexes, incorporating principles applicable to the triceps reflex.
- Patient Positioning: Position the patient comfortably with the arm relaxed and slightly flexed at the elbow. The goal is to allow the triceps muscle to be easily accessed and relaxed. Support the arm to prevent any active muscle contraction.
- Muscle Tension: Put a little bit of tension on the muscle, but not too much. This involves gently supporting the arm and ensuring the triceps muscle is neither fully contracted nor fully relaxed.
- Tendon Identification: Locate the triceps tendon, which is found on the posterior aspect of the upper arm, just proximal to the elbow.
- Striking the Tendon: Use a reflex hammer to briskly tap the triceps tendon. The strike should be direct and quick.
- Observe the Response: Watch for a visible contraction of the triceps muscle, which extends the elbow. This is the expected normal response.
Example
- The examiner supports the patient's upper arm, allowing the lower arm to hang loosely.
- The triceps tendon is located just above the elbow on the back of the arm.
- A tap on the tendon with the reflex hammer should cause the elbow to extend as the triceps muscle contracts.
