What type of gait presents as a sudden, abrupt inability to initiate any movement?

The type of gait that presents as a sudden, abrupt inability to initiate any movement is known as freezing. This phenomenon is commonly observed in individuals with Parkinson's disease and is characterized by a temporary inability to start walking or a sudden halt while walking. During freezing episodes, the person may feel as though their feet are glued to the ground, leading to a significant disruption in their gait pattern. It often occurs when transitioning between activities, navigating obstacles, or in situations with increased stress or distraction.

Understanding freezing is essential for physical therapy and rehabilitation practices, as it directly impacts mobility and independence in those affected. Distinguishing freezing from other gait patterns, such as festinating or spastic gait, is crucial in developing appropriate interventions and treatment strategies.
