How long after surgery for disc herniation can people safely perform abdominal and back exercises with dynamic hip and back extension?

• A. Six months
• B. One year
• C. Eighteen months
• D. Two years

Answer: (B)

After disc herniation surgery, progressing to abdominal and back exercises that involve dynamic hip and back extension depends on healing and spinal stability. These extension movements place load on the healing tissues and discs, so they’re typically deferred until tissues have matured and the surgeon or physical therapist clears progression. A common, cautious timeline often cited is about one year, by which time scar tissue has remodeled, neuromuscular control has improved, and the spine is better able to tolerate higher-load, dynamic movements without increasing the risk of re‑injury. Six months is usually too early for these specific high-load extension exercises, while eighteen months or two years are more conservative or case-dependent than necessary for most patients. Always follow the individual medical and rehab guidance for the safest progression.
