ABSTRACT
Objective:To investigate the characteristics of gait festination in patients with Parkinson's disease. Methods:From January, 2016 to January, 2018, 20 Parkinson's disease patients with festination (festination group), other 20 Parkinson's disease patients without festination (non-festination group) (all in ON stage) and 20 healthy controls were tested BTS Motion Capture System and analyzed with SmartAnalyzer. Results:The stride time, swing time of left side and maximum ankle dorsiflexion angle of left side decreased in the festination group compared with those in the non-festination group, while the first peak of ankle appeared earlier (P < 0.05). The stance phase increased in the festination group compared with those in the controls (P < 0.05), while the swing phase, stride length, step length and velocity decreased, as well as the maximum ankle plantar flexion (P < 0.05), and the first peak of ankle appeared earlier (P < 0.05). Conclusion:Festination is characterized as less step length, faster step cadence and slower velocity. The first peak of ankle appeared earlier for the center of mass moving foreward. The maximum plantar flexion angle of the ankle reduces for the poor balance function.
