Study Overview
Brief Summary
The purpose of this research is to examine effects of movement training with the aid of rhythmic auditory stimulation (RAS) on reducing severity of dyskinesia and bradykinesia in at-risk individuals and schizophrenia patients. The investigators hypothesize that training with the aid of RAS reduced severity of bradykinesia and dyskinesia in at-risk individuals as well as in schizophrenia patients.

Arms & Interventions
schizophrenia- RAS
Schizophrenia patients in the experimental group will undergo upper-limb movement training with the aid of rhythmic auditory stimulation (RAS).
Intervention: Rhythmic auditory stimulation (RAS) for schizophrenia patients (Behavioral)
schizophrenia- no RAS
Schizophrenia patients in the control group will receive upper-limb training without the aid of RAS.
Intervention: No RAS for schizophrenia patients (Behavioral)
at risk- RAS
At-risk individuals in the experimental group will undergo upper-limb movement training with the aid of RAS.
Intervention: RAS for at-risk individuals (Behavioral)
at risk- no RAS
At-risk individuals in the control group will receive upper-limb training without the aid of RAS.
Intervention: No RAS for at-risk individuals (Behavioral)
