The aim of this prospective quasi-experimental study was to explore the influence of biofeedback training on patients with functional constipation (FC). Changes in clinical symptoms, psychological status, quality of life, and autonomic nervous function in 21 FC patients before and after biofeedback training were investigated. The psychological status and quality of life were evaluated with the Zung Self-Rating Anxiety Scale (SAS), Zung Self-Rating Depression Scale (SDS), and a Chinese version of the MOS 36-Item Short-Form Health Survey. Autonomic nervous function was assessed on the basis of heart rate variability recorded with a HANS-1000 autonomic nervous biofeedback apparatus. After a complete course of training (10 sessions), clinical symptoms were greatly improved (p < .01), and the SAS and SDS scores were markedly decreased. There was a significant difference in the SAS and SDS scores before and after biofeedback (p < .01). The scores of general health perceptions, physical functioning, emotional role functioning, bodily pain, and vitality were increased significantly (p < .05), especially the scores of general health perceptions and emotional role functioning (p < .01), which indicated that quality of life in FC patients was significantly improved. No marked improvement of autonomic nervous function was found. Although a slight improvement in autonomic nervous activity was found, there was no significant statistical findings (p > .05). We conclude that biofeedback training can improve clinical symptoms, psychological status, and quality of life in FC patients, but further research is needed to determine whether biofeedback training can improve the autonomic nervous function in FC patients.
这项前瞻性准实验研究的目的是探讨生物反馈训练对功能性便秘（FC）患者的影响。研究了21例FC患者在生物反馈训练前后临床症状、心理状态、生活质量和自主神经功能的变化。采用zung自评焦虑量表（SAS）、zung自评抑郁量表（SDS）和中文版MOS 36项简短健康调查问卷评估心理状态和生活质量。基于用HANS-1000自主神经生物反馈仪记录的心率变异性评估自主神经功能。经过一个完整疗程（10次治疗）的训练后，临床症状有显著改善（p<0.01），SAS和SDS评分明显降低。生物反馈前后SAS和SDS评分有显著差异（p<0.01）。总体健康感知、身体功能、情感角色功能、身体疼痛和活力得分显著提高（p<0.05），尤其是总体健康感知和情感角色功能得分（p<0.01），这表明FC患者的生活质量有显著改善。未发现自主神经功能有明显改善。虽然发现自主神经活动略有改善，但无显著统计学结果（p>0.05）。我们得出结论，生物反馈训练可以改善FC患者的临床症状、心理状态和生活质量，但需要进一步研究以确定生物反馈训练是否能改善FC患者的自主神经功能。
