70 RESEARCH ON THE ROLE OF VOCAL TRAINING IN IMPROVING COGNITIVE FUNCTION OF PATIENTS WITH SCHIZOPHRENIA

Abstract Background Schizophrenia patients exhibit sensory and behavioral abnormalities, and the current common intervention treatment mainly uses drugs to block dopamine receptors in the brain. However, the cognitive function of patients with schizophrenia cannot be cured through medication. In current interventions for schizophrenia, vocal training therapy can regulate the patient’s breathing rhythm, maintain their heart rate and emotions, relax their mood and body, thereby increasing their resistance to stressful situations. Therefore, the study explored the positive effects of vocal training on cognitive function training in patients with schizophrenia. Methods A study was conducted on 150 patients with schizophrenia, who were evenly divided into a control group and an experimental group, with 75 patients in each group. The control group received routine nursing methods and the nursing time was maintained for 6 months. The experimental group added soothing vocal training activities on the basis of routine care, twice a week for 30 minutes each time. The same intervention lasted for 6 months in the experimental group. After intervention, Stroop color word test was used to evaluate patients’ cognitive function. Results The study will evaluate the cognitive function level of patients with schizophrenia based on the Stroop color word test results before and after intervention in the experimental and control groups. The specific results are shown in Table 1. From the table, it can be seen that the control group scored 97.32±1.27 and 97.87±1.40 before and after intervention in the A card test, respectively. The scores of the experimental group before and after intervention were 97.65±1.27 and 99.70±0.46, respectively. In the detection of the B card, the scores of the control group before and after intervention were 94.75±1.77 and 95.18±2.22, respectively, while the detection scores of the experimental group were 95.10±1.66 and 98.73±1.04, respectively. In the C card, the scores of the control group before and after intervention were 87.20±3.83 and 88.08±3.76, respectively. The scores of the experimental group before and after intervention were 86.53±3.55 and 95.60±2.12, respectively. From the data results, it can be seen that the experimental group showed a greater increase in Stroop color word test scores after intervention, indicating that vocal training can effectively improve cognitive function in patients with schizophrenia. Discussion The experimental results indicate that the intervention method of vocal training can improve patients’ thinking expression ability and memory by soothing their physical and mental health, and through vocal music. Through vocal training, patients with schizophrenia can enhance their self-identity through beautiful musical works and singing behavior, thereby improving their psychological state and cognitive function, enhancing their self-management level and quality of life.
