As Parkinson’s disease (PD) progresses, people with PD may experience freezing of gait or “freezing” episodes. Freezing of gait is the temporary, involuntary inability to move. Not all people with PD experience freezing episodes, but those who do have a greater risk of falling. Usually, freezing only lasts a few seconds, but it is one of the more frustrating and dangerous symptoms of PD. You may not always be able to prevent a freezing episode, but recognizing when this PD symptom may happen con minimize injury.
