Degenerative lumbar spinal stenosis and physical functioning: an exploration of associations between self-reported measures and physical performance tests.

The present study indicates that both self-reported symptoms and walking limitation are associated with leg strength, while only symptoms are associated with balance. The results suggest that a combination of simple performance tests will add information needed to map the patients disability and guide interventions. Implications for Rehabilitation One-leg-standing, 30-s sit-to-stand and stair climb test are easy to use and applicable for examining physical function in patients with lumbar spinal stenosis (LSS). Simple performance tests add information needed to map the patients' disability and guide interventions. Leg strength is a key factor for both symptoms and walking ability. Also, balance is of importance for the symptoms in LSS patients.
