Filter by:Introduction Bradykinesia (i.e., slow movements) is one of the most prominent symptoms of Parkinson's disease (PD) and has a negative impact on quality of life. Rhythmic auditory stimulation (RAS), a widely used and promising treatment technique, has been shown to effectively improve gait speed in PD patients. However, only few studies have explored effects and neural mechanisms of RAS on upper-limb movements. The investigators will conduct two studies to investigate effects and mechanisms of RAS on upper-limb movements in PD patients. The purpose of this study is to examine real-time neural activity when patients with PD and healthy controls listen to RAS and execute finger-tapping task simultaneously. Methods and analysis This study will recruit patients with PD and healthy controls. Electroencephalography (EEG) will be used under six conditions related to a finger-tapping task. Two-way repeated measures analysis of variance will be performed to investigate the group and condition effects on neural mechanisms. Study significance This study will offer evidence on RAS effects and mechanisms by investigating the changes in upper-limb movements and neural mechanisms during auditory-motor entrainment. Results from this study will provide a solid foundation for further research and clinical applications of RAS.
Introduction Bradykinesia (i.e., slow movements) is one of the most prominent symptoms of Parkinson's disease (PD) and has a negative impact on quality of life. Rhythmic auditory stimulation (RAS), a widely used and promising treatment technique, has been shown to effectively improve gait speed in PD patients. However, only few studies have explored effects and neural mechanisms of RAS on upper-limb movements. We will conduct two studies to investigate effects and mechanisms of RAS on upper-limb movements in PD patients. The purpose of this study is to examine effects and neural mechanisms of upper-limb movement training involving RAS in PD patients. Methods This study will recruit patients with PD and healthy controls. This study will randomly assign PD patients into two groups: the PD-RAS group and the PD-noRAS group, and healthy controls into the HC-RAS group and the HC-noRAS group. A 7-day upper-limb training involving RAS (for the PD-RAS group and the HC-RAS group) or without RAS (for the PD-noRAS group and the HC-noRAS group) will be provided. EEG and behavioral assessments will be conducted before and after the first day of training, and after the seven-day training program. Two-way repeated measures analysis of variance will be performed to investigate the group and time effects on upper-limb function and neural activity. Study significance The training program will serve as a reference for clinical practitioners who are interested in using RAS in clinical training for PD patients.
The goal of this clinical trial is to examine effects of training involving rhythmic auditory stimulation (RAS) on upper-limb movements and functions in patients with Parkinson's disease (PD). Patients will be randomly divided into two groups: the RAS group and the no-RAS group. Patients will receive training with or without the aid of RAS based on their groups. The training task is to use the right hand to take beads from one bowl to another bowl. The box and block test and the Jebsen hand function test will be used before and after training (i.e., pretest and posttest respectively) to assess patients' upper-limb speed and function. Researchers will compare scores of the box and block test and the Jebsen hand function test between the two groups at pretest and posttest to determine effects of RAS.
In this experiment, patients with chronic pure tone tinnitus were divided into three groups to receive auditory stimulation, somatosensory stimulation, vestibular stimulation and combined stimulation, in order to find an effective way to treat tinnitus
