目的：探讨针刺“枕后七穴”对持续性姿势性–知觉性头晕(PPPD)患者焦虑、抑郁情绪及临床症状的改善效果。方法：将96例PPPD患者随机分为治疗组(针刺“枕后七穴”，n = 48)与对照组(口服草酸艾司西酞普兰片，n = 48)，治疗28天后比较两组汉密尔顿抑郁量表(HAMD)、汉密尔顿焦虑量表(HAMA)、中医眩晕症状观察量表评分及临床疗效评价。结果：治疗后，治疗组在HAMD、HAMA评分下降幅度显著优于对照组(P Objective: To investigate the effects of acupuncture at the “seven acupoints behind the occiput” on anxiety, depression, and clinical symptoms in patients with persistent postural-perceptual dizziness (PPPD). Methods: A total of 96 PPPD patients were randomly divided into a treatment group (acupuncture at the “seven acupoints behind the occiput,” n = 48) and a control group (oral escitalopram oxalate tablets, n = 48). After 28 days of treatment, the Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Traditional Chinese Medicine (TCM) dizziness symptom observation scale scores, and clinical efficacy evaluations were compared between the two groups. Results: After treatment, the reduction in HAMD and HAMA scores in the treatment group was significantly greater than in the control group (P < 0.05), and the improvement in TCM dizziness symptom observation scale scores was more pronounced (P < 0.01). The total effective rate in the treatment group was 93.75%, which was higher than the 64.58% in the control group (P < 0.05). Conclusion: Acupuncture at the “seven acupoints behind the occiput” significantly alleviates anxiety, depression, and dizziness symptoms in PPPD patients. Its clinical efficacy is superior to drug intervention, demonstrating high application value.
