Freezing

Abb1.: Center of Mass (COM), center of gravity (COG) und center of pressure (COP) bei der Posturographie.

Freezing of gait (FOG) in Parkinson's disease is a “brief, episodic absence or marked reduction of forward progression of the feet despite having the intention to walk” (Giladi & Nieuwboer, 2008), often subjectively described by the patients as the "feeling that their feet get glued to the ground". FOG often occurs when initiating gait, during turning, when passing doorways or when reaching a target.

This project investigates the relationship of FOG and postural control deficits in Parkinson's disease. We are interested in whether postural control deficits contribute to FOG or, alternatively, whether altered postural control compensates for FOG. Neuromechanical analyses are applied to get a detailed view of the different postural control domains and to investigate the underlying mechanisms of locomotion.

This project is funded by the Coppenrath-Foundation and Krumme-Foundation.
