Spinal stenosis: Which activity is most likely to be avoided?

• A. Stretching while lying down
• B. High-impact exercises
• C. Low-impact exercises
• D. Physical therapy

Answer: (B)

In spinal stenosis, symptoms come from the nerves being compressed in a narrowed spinal canal, and this compression is worsened by activities that load the spine or jolt it. High‑impact activities—like running or jumping—impose substantial axial load and repetitive vibration on the spine, which increases nerve irritation and neurogenic claudication. That makes them the type of activity most likely to be avoided. Low‑impact activities and physical therapy, on the other hand, tend to preserve or improve conditioning while minimizing spinal loading. They can help maintain mobility and strengthen the core to support the spine. Stretching while lying down may be neutral or even helpful for some patients, depending on symptoms.
