简要总结
The goal of this clinical trial is to explore the benefits of autonomy supported learning in patients with Parkinson's disease. The main questions to answer are:
- Whether autonomy supported learning can benefit motor learning in PD patients
- Whether autonomy supported learning can enhance intrinsic motivation and/ or information processing of PD patients in learning a new task.
- Whether autonomy supported learning can facilitate cortical excitability change after practicing a new task.
Participants will be recruited into two groups (Self-control group, SC; and yoked group, YK) to learn a finger-pressing trajectory matching task
- Participants in SC group will have choice over feedback schedule during trial practice
- Participants in YK group will receive feedback with no-choice during trial practice Researchers will compare the retention test performance to see if autonomy supported learning will lead to better learning effect.
详细描述
Autonomy is the sense of learner to actively participate in determining their own behaviour. The present study aims to investigate whether an autonomy supported practice (with self-controlled feedback) would benefit adults with Parkinson's disease (PD), along with increased intrinsic motivation, information processing and cortical excitability. Two groups of healthy adults and two groups of PD patients will be recruited to learn a finger-pressing trajectory matching task. Participants will be allocated in either a self-control group (choice over feedback schedule), or a yoked group (receive feedback with no-choice). Learning will be assessed on the second day and one week later, along with an error estimation of learners' own performance to represent their information processing ability. Cortical excitability and inhibition will be assessed via transcranial magnetic stimulation as indicators of cortical plasticity. Questionnaire regarding motivation will be assessed before and after practice trials. Study hypothesized that individual with PD would benefit from autonomy supported learning, with better performance, enhanced motivation and information processing, associates with change of cortical excitability

研究组 & 干预措施
Self-control group
Participants will be able to choose over feedback schedule when practicing finger-pressing trajectory matching task.
干预措施: Autonomy supported learning (Behavioral)
Yoked group
Participants will receive feedback, which was determined by their counterpart in self-control group, with no-choice when practicing finger-pressing trajectory matching task.
干预措施: Practice with predetermined feedback (Behavioral)
结局指标
主要结局
Performance accuracy
时间窗: up to day 7
Overall performance accuracy relative to the target waveform was assessed using root mean square error (RMSE), which is the mean difference between the target waveform and the participant's movement trajectory calculated over their actual movement time.
次要结局
- Intrinsic Motivation Inventory(day 1, day 2, day 7)
- Error Estimation(day 2, day 7)
- Cortical excitability changes(Baseline, day 2, day 7)
