How long does exercise therapy take to work for spondylolysis?

Spondylolysis is a stress-related defect in part of a vertebra, often in the lower back. Back pain may be linked to repeated extension, rotation, or sport-specific loading. A programme may first settle irritation and maintain comfortable movement, then build trunk, hip, and back strength. Improved control during everyday tasks is a useful early sign; it does not automatically mean the back is ready for maximal lifting, jumping, or competition.

Keep to the activity limits and exercise schedule agreed with your clinician. Progress only when the current level is controlled and symptoms are settling between sessions. Warm up before activity, avoid repeatedly testing painful back extension, and record how your back responds later that day and the next morning. A physiotherapist can adapt the plan as strength and sport demands change. Read about [Exercise Therapy](/treatments/physiotherapy-and-rehabilitation/exercise-therapy/).

Arrange a review if pain persists despite modifying activity, returns with each progression, or starts affecting sleep and ordinary movement. New leg pain, numbness, weakness, fever, or pain after a significant injury needs medical assessment. Seek urgent care for severe weakness, loss of bladder or bowel control, or numbness around the groin.

Which activities are safe at my current stage? What signs show that I can add resistance or sport drills? Should imaging or a specialist review be considered if progress stops?
