生物反馈治疗军事飞行员原发性高血压的疗效分析

Curative effect analysis of electromyographic biofeedback in military pilots with hypertension

目的探讨肌电生物反馈对飞行员原发性高血压的治疗效果。方法对160例患有原发性高血压飞行员进行为期8周的肌电生物反馈治疗,2次/d,每次30 min。测定治疗前后患者血压、额肌肌电值的变化,并以焦虑自评量表(SAS)和自评抑郁量表(SDS)评价其心理状况。结果经8周治疗后,患者额肌肌电值、SAS评分明显低于治疗前(P<0.05和P<0.01)。收缩压自治疗第2周起显著降低(P<0.05),舒张压自第4周起显著降低(P<0.05),至治疗结束时,血压仍保持相对稳定(P<0.01)。而治疗前后SDS评分变化差异无统计学意义(P>0.05)。结论肌电生物反馈能够有效降低患者肌肉紧张度,改善心理功能,从而达到治疗飞行员原发性高血压的目的。

Objective To analyze the curative effect of electromyographic biofeedback in military pilots with hypertension. Methods 160 cases of pilots who suffered from essential hypertension were treated with electromyographic biofeedback for 8 weeks,twice daily and 30 min each time.Blood pressure and EMG changes of frontalis were determined in patients before and after treatment.psychologic status of patients were evaluated according to self-rating anxiety scale（SAS） and self-rating depression scale（SDS）. Results After 8 weeks treatment,EMG of frontalis and SAS score were significantly lower than that before the treatment（P0.05 and P0.01）.Systolic pressure was significantly decreased from the second week of treatment（P0.05） and remained relative stable until the end of treatment（P0.01）.The score changes of SDS had no statistical significance（P0.05）. Conclusion Electromyographic biofeedback can effectively reduce the muscle tone of patients and improve the mental function to treat the hypertension in pilots.
