PD patients walked slower with shorter stride-length, comparable cadence, and longer double support times. Kinematics showed a reduction of the range of motion in the hip, knee, and ankle joints. Maximum hip extension and the ankle plantar flexion were significantly reduced. Kinetic gait parameters showed reduced push-off ankle power and lift-off hip power generation. Strong correlations between these important body advancement mechanisms and the walking velocity were observed.
koeselitz: ... while I can support any theory that ascribes dementia to Agatha Christie, this one doesn't make any sense. Writers sometimes use simple sentence structure, and sometimes more complex. Writers who use simpler sentences than other writers are not necessarily Alzheimer's sufferers. The same goes for vocabularies. The idea that these things are correlated seems laughable to me when there are clearly reasons why a writer might want to simplify sentence structure and vocabulary on purpose.
