Physical Therapy Assistant Practice Exam

What is the starting position for the D1 extension pattern?

1. Shoulder flexion

2. Shoulder extension

3. Shoulder adduction

4. Shoulder abduction

The correct answer is: Shoulder extension

The D1 extension pattern is part of the PNF (Proprioceptive Neuromuscular Facilitation) techniques commonly used in physical therapy to promote functional movement patterns. The starting position for this pattern is characterized by the shoulder being in extension, along with a specific hand position to facilitate the movements associated with this pattern. In the D1 extension pattern, the arm is positioned behind the body, moving from a flexed and adducted position to an extended and abducted position. This requires the shoulder to begin in extension to initiate the movement effectively. As for this extension position, the practitioner encourages patients to move in a way that promotes the integration of the entire limb, addressing both strength and coordination. Understanding the starting position as shoulder extension is critical when applying these therapeutic techniques, as this ensures that subsequent movements align with the established patterns in rehabilitation practices. The correct starting position enables proper activation of muscles involved in the extension movement, allowing for a more effective therapeutic outcome.
