After being diagnosed with Parkinson’s disease in 2002, Larry Walleyn developed gait freezing. He had a hard time getting around, sometimes he couldn’t move at all and falls were frequent. His symptoms caused him to lose much of his independence.
Gait freezing is a symptom of Parkinson’s disease. It hinders the ability to produce continuous stepping movements. Freezing is unpredictable, which increases the risk of falls and injuries. Freezing episodes can be as short as a few seconds or can last hours.
