Device and method for determining a severity of fog

A method for determining a severity of Freezing Of Gait (FoG) in a patient, the method comprising:

• instructing a patient to conduct a predefined gait sequence;
• using a FoG analysis device having a FoG registration interface comprising two thumb-actuated buttons for registering the FoG status of the patient as “FoG” (experiencing FoG) or “no FoG” (not experiencing FoG) while the predefined gait sequence is conducted, wherein the FoG status is registered by:
• when a first FoG event occurs, using a predefined “FoG” thumb to actuate the button indicating “FoG”;
• when the first FoG event stops occurring, using the predefined “no FoG” thumb to actuate the button indicating “no FoG”;
• and
• during what remains of the predefined gait sequence, for each change in the patient's FoG status, using the predefined thumbs to register the FoG status as either “FoG” or “no FoG”;
• and
• based on these registrations of the FoG status, determining the amount of time the FoG status of the patient was registered as “FoG” as a percentage of the total time for the predefined gait sequence.

A non-transitory computer-readable medium comprising instructions which, when read by a computer, cause the computer to:

• display a FoG registration interface comprising two thumb-actuated buttons for registering a FoG status of a patient as “FoG” (experiencing FoG) or “no FoG” (not experiencing FoG);
• allow the FoG status to be registered while a predefined gait sequence is conducted by the patient, by:
• initially setting the FoG status to “no FoG”;
• in response to the actuation of the button indicating “FoG”, setting the FoG status to “FoG”;
• and
• in response to the actuation of the button indicating “no FoG”, setting the FoG status to “no FoG”;
• based on these registrations of the FoG status, determine the amount of time the FoG status of the patient was registered as “FoG” as a percentage of the total time for the predefined gait sequence;
• and
• output the determined FoG percentage.
