Adaptive SCS for Treatment of Gait Disturbance in PD

Status Recruiting

Clinical Trial Summary

Spinal cord stimulation (SCS) has been suggested by several research for treating PD gait disturbance. However, the side effects induced by body position change cannot fully addressed by conventional SCS. Medtronic sensor-driven position-adaptive SCS are capable to monitor the position change and change the parameters accordingly, so as to reduce the position change related side effects. Nevertheless, neither the efficacy nor safety of this technique in the treatment of gait disturbance in PD is ever investigated. Therefore, the investigators will conduct a randomized clinical trial to investigate the clinical efficacy and safety of sensor-driven position-adaptive SCS in the treatment of gait disturbance in PD. This study will contribute to find out the safety and efficacy of sensor-driven position-adaptive SCS in the treatment of PD gait disorder, improve patients' quality of life, and reduce the burden on family and society.

Clinical Trial Description

The study is a randomized double-blind crossover design aiming to test the short-term efficacy and safety of sensor-driven position-adaptive SCS in the treatment of gait disturbance in patients with PD. More than 1 month after operation, subjects will be randomly assigned into two groups, with one group treated with conventional spinal cord stimulation intervention and the other treated with sensor-driven position-adaptive spinal cord stimulation intervention. Both groups will be followed-up for more than 1 week and receive comprehensive evaluation. A cross-over design will then be applied to eliminate the individual variability until both groups complete another 1 week follow-up. Stimulation parameters and levodopa equivalent daily dose (LEDD) remained during follow-up in both group. Clinical evaluation is assessed by 6-min walk test (6MWT) and timed up-and-go task (TUG) with gait analysis. Quality of life is evaluated by The 5-level EQ-5D. The severity of PIGD is assessed by gait and fall questionnaire (GFQ) , modified fall efficacy scale(MFES), activities-specific balance confidence (ABC) scale and the survey of activities and fear of falling in the elderly (SAFFE ). Within group t test will be made for comparison between two groups. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
