Understanding the Freezing of Gait Questionnaire (FOGQ)
The Freezing of Gait Questionnaire (FOGQ) is a valuable tool for assessing the severity and frequency of freezing of gait (FOG) in Parkinson’s disease patients. It’s a clinician-administered, patient-reported scale, providing a quantitative measure of FOG impact on daily life and independence.
What is the Freezing of Gait Questionnaire?
The Freezing of Gait Questionnaire (FOGQ) is a widely used assessment tool specifically designed to measure the severity and frequency of freezing of gait (FOG) experienced by individuals with Parkinson’s disease (PD). This six-item questionnaire employs a four-point Likert scale (0-3) for each question, enabling clinicians to quantify FOG’s impact on daily activities. Higher scores indicate more pronounced FOG. The FOGQ assesses various aspects of FOG, including its duration, frequency, and the situations that trigger it, providing a comprehensive picture of the patient’s experience. While the FOGQ focuses on FOG severity unrelated to falls, it provides valuable insights into the challenges faced by patients in their daily routines. Its concise format allows for efficient administration, making it a practical tool for clinical settings and research studies.
