Abstract | OBJECTIVE: METHODS: Instrumental gait analysis was performed in 38 out of 40 patients with wearing-off phenomenon during a randomized, double-blind, placebo-controlled trial of tolcapone. RESULTS: Gait analysis disclosed a significant improvement by levodopa/ benserazide in walking speed, stride length and the range of motion of hip, knee and ankle joints. At the end of the study, both the UPDRS motor scores during off-period and the percentage of off time improved significantly using tolcapone. However, gait analysis could not confirm this improvement. With respect to levodopa/ benserazide effect, the reduction in rigidity correlated with improved angular excursion of the ankle, whereas the decreased bradykinesia correlated with improved stride length and angular excursion of the hip and knee joints. CONCLUSION: The results of our gait analysis confirmed that in parkinsonian patients with fluctuating motor symptoms levodopa/ benserazide, but not tolcapone, produced a substantial improvement.
