Slow to start walking; stride length reduced; festination (rapid short accelerating steps); problems in stopping an changing sequential movements; less arm swing; poor balance when turning; difficulty crossing obstacles; less toe elevation at heel strike; increase in stance phase and double support phase duration; increased variability of gait; more difficulty walking when performing simultaneous motor or cognitive tasks. Gait abnormalities increase risk for falling.
Gait analysis has been used to demonstrate the effectiveness of drug treatment of Parkinson’s . Those on active treatment versus placebo had a greater stride length and a decrease in double support time. Force plate analysis has shown the second peak to be significantly reduced in size with asymmetry in duration of the stance phase
