title: The challenge of evaluating freezing of gait in patients with Parkinson's disease.
abstract: Freezing of gait (FOG) poses difficulties for measurement as it is highly sensitive to environmental triggers, cognitive input and medication. To ensure valid and reliable measurement of FOG, a combined methodology is recommended relying on tests of complex gait during the off-period together with a FOG-questionnaire, addressing severity and impact of freezing on daily life.
