Primary Outcome Measures

Name	Time	Method
Validate the newly-developed ClinRO	12/2025	Rate scale of freezing of gait to detect meaningful improvement in freezing of gait. The scale name is " Freezing Of Gait Severity Score". it consist a 8 trials, each one can be rate between 0 to 8. the scale consist a part of frequency of the freezing and part of cumulative duration. The higher the score, the more severe the stagnation and the lower it is, the less stagnation is present.

Secondary Outcome Measures

Name	Time	Method
Asses the importance of the FOG symptom for patients	12/2025	Severity of freezing of gait (FOG) symptoms and patient-reported impact on quality of life. The scale name is " Freezing Of Gait Severity Score". it consist a 8 trials, each one can be rate between 0 to 8. the scale consist a part of frequency of the freezing and part of cumulative duration. The higher the score, the more severe the stagnation and the lower it is, the less stagnation is present.
