About
Freezing of gait (FOG) is a common yet poorly understood motor symptom in persons with Parkinson's disease (PD). Previous studies have shown that bilateral uncoordinated gait and gait asymmetry are related to FOG, and that intensive treadmill training in PD patients can improve gait. However, no group has yet studied the effect of robot-assisted gait training (RAGT) on FOG. The primary aim of this study is to collect pilot data on the effect of robot-assisted gait training in reducing episodes of freezing in PD.
Subjects with Parkinson's disease that experience freezing of gait will be recruited and enrolled following informed consent and screening for eligibility. Each of the 10 training session will last approximately one hour. Neurological evaluations, testing of gait parameters, and quality of life assessments will be conducted. Participants will also be asked to return for 1- and 3-month post-intervention assessments to see if the training has any lasting effects. Approximately 10-20 subjects will be enrolled, and the study will last up to 6 months.
Robot-assisted gait training will be conducted with the Lokomat (a treadmill with supplemental robot-assistance for moving the hip and knee). We will monitor changes in freezing by conducting various assessments.
There are approximately 1 million Americans with PD in the US. PD is a significant cause for reduced functional ability and quality of life, progressive disability. Patients with PD with FOG have indicated that this is one of their most disturbing symptoms, as there are no effective treatments. Therefore it is important that additional and alternative interventions for FOG be tested and developed.
