Full Form of FOG
What is FOG?
Freezing of Gait, commonly abbreviated as FOG, is a debilitating and highly distressing motor symptom most frequently observed in patients suffering from Parkinson's disease and related parkinsonian disorders. It is defined as a sudden, brief, and episodic absence of forward locomotion during which the patient's feet feel as though they are glued or magnetically attached to the ground, despite a strong conscious intent to walk. In India, where Parkinson's disease affects an estimated one million people, FOG is recognised as one of the most disabling clinical features and a leading cause of falls, hip fractures, hospitalisation, and progressive loss of independence among the elderly population. Neurologists and movement disorder specialists across premier Indian hospitals such as AIIMS, NIMHANS, JIPMER, and Apollo routinely screen and assess FOG using validated clinical scales like the Freezing of Gait Questionnaire and objective gait analysis systems. The symptom is widely discussed in geriatric medicine, physiotherapy, occupational therapy, and rehabilitation settings. The phenomenon is frequently tested in postgraduate medical entrance examinations, including NEET-PG, AIIMS-PG, and DM Neurology, where candidates are expected to identify its pathophysiology, common triggers, and evidence-based treatment options such as auditory cueing, visual cues, and dopaminergic medication adjustment.

FOG — frequently asked questions
What is the full form of FOG in medical terms?
The full form of FOG is Freezing of Gait, a sudden and episodic motor symptom commonly seen in patients with Parkinson's disease where the feet feel stuck to the ground while attempting to walk.
What causes Freezing of Gait in Parkinson's patients?
FOG is primarily caused by the degeneration of dopaminergic neurons in the basal ganglia, and is often triggered by turning, narrow spaces, stressful situations, dual-tasking, or when dopaminergic medication levels drop between doses.
How is Freezing of Gait treated in India?
Treatment options available in India include dopaminergic medication adjustment by neurologists, auditory and visual cueing therapy, deep brain stimulation (DBS) surgery, physiotherapy, and balance training programmes offered at major hospitals like AIIMS and NIMHANS.
