Freezing of gait (FOG) is defined as a brief, episodic absence or marked reduction of forward progression of the feet despite the intention to walk. It is one of the most debilitating motor symptoms in patients with Parkinson's disease (PD) as it may lead to falls and a loss of independence.
Parkinson’s disease alters the function of brain circuits that facilitate the automatic synchronous movements involved in ambulation and other complex motions.
“Freezing of gait” is often triggered by specific activities or circumstances that demand switching between motor actions. Some patients might “freeze” when walking through narrow passages or doorways, trying to get on and off elevators, when turning or changing directions, and when walking in busy crowds.
Techniques to reduce freezing of gait:
Try another movement – raise an arm, touch your head, point to the ceiling, then start walking again.
Change direction: if you can’t move forward, try stepping sideways first, and then go forward
Visualize an object on the ground in front of you and try to step over it.
Wear the right shoes and walk with intention.
Try to relax and take a deep breath.
Count “1-2-3-go” and then step forward
Try humming a song and time your re-start with the beat of the music
Shift your weight from side to side to help initiate taking a step
March in place a few times and then step forward
