Gait & Parkinson's: Research papers
- Movement orientation switching with the eyes and lower limb in Parkinson disease
In PD, switch time and movement velocity of the lower limb, but not the eyes, correlated with bradykinesia and postural instability/gait. Study results suggest that individuals with PD experience movement-switching deficits with both the eyes and lower limb, perhaps driven by overall bradykinesia.

- ''On'' state freezing of gait in Parkinson disease: A paradoxical levodopa-induced complication
Conclusions: True on FOG exists as a rare phenotype in PD, unassociated with cognitive impairment or a predating off FOG. Distinguishing the different FOG subtypes requires a comprehensive motor assessment in at least 3 medication states.

- Assessing the utility of Freezing of Gait Questionnaires in Parkinson's Disease
This study demonstrate a potential role for sAPPα and sAPPβ in distinguishing between PS, a finding that needs to be confirmed in future studies of larger cohorts. There is a tendency towards low levels of Aβ(1-42) in DLB patients in this cohort.

- Impaired Economy of Gait and Decreased Six-Minute Walk Distance in Parkinson's Disease
This study investigated economy of gait during submaximal treadmill walking in 79 subjects with mild to moderate PD and the relationship between gait economy and 6-minute walk distance (6 MW).

- Walking Ability Is a Major Contributor to Fear of Falling in People with Parkinson's Disease: Implications for Rehabilitation
These results have implications for rehabilitation clinicians and suggest that walking ability is the primary target in order to reduce FOF. Specifically, balance, climbing stairs, and turning seem to be of particular importance.

- Gait Difficulty, Postural Instability, and Muscle Weakness Are Associated with Fear of Falling in People with Parkinson's
This is the first study to demonstrate that the UPDRS-PG score and knee muscle strength are important and independent determinants of the level of fear of falling in individuals with PD. Improving balance, gait stability and knee muscle strength could be crucial in promoting balance confidence in the appropriately targeted PD population.
