Fig. 2. Effect of cholinesterase inhibitors (ChEIs) on the gait speed and step/stride variability of patients with Parkinson disease (PD).
a ChEIs did not significantly increase gait speed in patients with PD (Mean Difference [MD]: 0.03 m/s, 95% confidence interval [CI]: −0.02 to 0.07, p = 0.29). b A significant beneficial effect on step or stride variability during the single task (Standardized MD [SMD]: −0.43, 95% CI: −0.79 to −0.06, p = 0.02) was demonstrated.
