For neck pain with mobility deficits, which ultrasound approach is supported in chronic cases?

• A. Pulsed US
• B. High-power continuous US
• C. Ultrasound is not recommended
• D. Pulsed or high-power US

Answer: (D)

In chronic neck pain with mobility deficits, ultrasound therapy can be beneficial using either pulsed or high-power continuous modes because each mode targets a different tissue response that can support recovery and function. Pulsed ultrasound provides non-thermal effects—like microstreaming and cavitation—that help promote tissue healing and reduce inflammatory irritability without significant heating. This can be advantageous when the goal is to facilitate repair and decrease tenderness in a chronic condition. High-power continuous ultrasound, by contrast, delivers thermal effects that raise tissue temperature, which can increase collagen extensibility, reduce muscle spindle activity, and improve range of motion. When stiffness and limited mobility are driving the symptoms, the heating effect can be particularly helpful. Since chronic neck pain with mobility deficits can benefit from either healing-oriented (pulsed) or mobility-enhancing (continuous) ultrasound, both approaches have clinical support. Therefore, the best answer is that either pulsed or high-power continuous ultrasound can be appropriate. Always apply with appropriate dose, duration, and patient monitoring to ensure safety.
