What is the recommended PT approach if subluxation/dislocation persists at high lumbar L1-L2?

• A. Continue ROM with caution
• B. Stop all movement immediately
• C. Perform aggressive high-load strengthening
• D. Switch to aquatic therapy exclusively

Answer: (A)

The main idea here is that when there is a persistent subluxation or dislocation at a high lumbar level (L1–L2), the goal of physical therapy is to preserve mobility and function while minimizing the risk of further instability. Continuing range-of-motion exercises in a controlled, cautious way keeps joints and soft tissues flexible, helps prevent contractures, and supports circulation and daily activities. This approach avoids sudden, high-stress movements that could worsen the subluxation or stress the spine beyond what is stable. It also avoids immobilizing the segment completely, which could lead to stiffness and deconditioning.

Aggressive high-load strengthening, in contrast, would place excessive demand on an already unstable spinal segment and could risk progression of displacement or neurologic symptoms. Stopping movement altogether would lead to loss of motion, strength, and circulation, which is not ideal for overall function. Relying exclusively on aquatic therapy might reduce joint loading, but it wouldn’t adequately address standing, weight-bearing control, and functional tasks needed for everyday activities or spinal stabilization.

So the recommended approach is to continue gentle, supervised range-of-motion activities with careful monitoring and progression within safe limits, aligning mobility maintenance with the stability concerns at that lumbar level. If any signs of worsening instability or new neurologic changes appear, reassessment and collaboration with the treating team are warranted.
