Which statement correctly describes the effect of flexion-distraction on neural elements?

Which statement correctly describes the effect of flexion-distraction on neural elements?

• A. It worsens neural compression
• B. It has no effect on neural elements
• C. It only affects muscles
• D. It reduces neural pressure

Answer: (D)

Flexion-distraction decompresses neural elements by gently distracting and flexing the spine, which increases the height of the intervertebral foramina and reduces pressure on the nerve roots. This technique creates negative pressure within the disc and can allow bulging material to retract, unloading irritated neural tissue and improving circulation around the nerves. The result is a decrease in neural pressure, helping to relieve radicular symptoms. It does more than affect muscles and does not worsen neural compression; its main effect is to relieve pressure on neural structures.
