Walkers can put you back in action if you're recovering from an injury or surgery, or if you're struggling with balance and gait problems, fatigue, or muscle weakness. "Walkers help give people their independence back. They improve daily function, and they reduce the risk of falling," says Dr. Clare Safran-Norton, a physical therapist and clinical supervisor of rehabilitation services at Harvard-affiliated Brigham and Women's Hospital.
