What is the most common physical therapy diagnosis?

Low back pain is the most common diagnosis treated in physical therapy. It affects people of all ages and activity levels and often results from poor movement mechanics, muscle imbalances, or prolonged sitting. Other common diagnoses include shoulder impingement, knee pain, neck pain, and post-surgical rehabilitation. Physical therapy focuses on identifying contributing factors rather than labeling pain alone. Treatment aims to restore movement efficiency, strength, and confidence to reduce recurrence.
