BackgroundGait impairment is common in people with Parkinson's disease. There is a lack of effective interventions to target this debilitating complication and therefore a need to identify new therapeutic options. An underlying cholinergic deficit contributes to both the gait and cognitive dysfunction seen in Parkinson's disease. The combined impact of both impairments can be assessed in gait tasks performed with concomitant cognitive tasks. The aim of this trial is to evaluate the impact of a cholinesterase inhibitor on cognitive function and gait performance in people with established Parkinson's disease.Methods/designThis is a single centre, double-blind, randomised placebo-controlled trial in 130 people with Hoehn and Yahr stage 2-3 idiopathic Parkinson's disease who have fallen in the past year. Participants will be randomised to two groups, receiving either rivastigmine capsules or identical placebo capsules for 8 months. Assessment will be undertaken at baseline and at the end of medication prescription (i.e. 8 months) with participants remaining enrolled in the trial for a further 4 months to monitor for falls and adverse events. The primary outcome is step time variability, assessed with and without the addition of concurrent cognitive tasks. Secondary outcomes will include other gait parameters, sensorimotor and balance performances, cognitive indices, falls and fall related injury, fear of falling, Parkinson's symptoms and data pertaining to possible harms.DiscussionThis randomised controlled trial will examine the effect of cholinesterase inhibitor therapy on gait, balance and falls in Parkinson's disease. If effective, it would offer a new therapeutic option to ameliorating gait and cognitive deficits in a population at high risk of falls.Trial registrationISRCTN19880883, UTN U1111-1124-0244.
