本文报导Gerber博士在美国国立卫生研究院进行的一项研究.20例雷诺现象(Raynaud’s phenomenon)患者经生物反馈方法训练,除一例失败外,余19例在3.3℃时能制止雷诺现象发作,对低温的反应近于正常.患者主观感觉好,他们感到比训练前轻松、不紧张,容易入睡、能较好地适应各种环境、冬季在户外或其它寒冷环境能做较多的事.20例患者都有原发或继发的雷诺现象,并经证实有典型的皮肤三色改变,即在寒冷或情绪紧张时皮肤颜色顺序变为苍白、青紫、潮红,在3.3℃冷室中皮肤温度迅速降低.将患者随机分为两组,每组十人,另有正常对照组十人.第一组患者每15秒钟用热敏电阻测定皮肤温度变化,并用连接光信号的一个仪器标示这种变化,温度上升或不变时光信号
This article reports a study by Dr. Gerber at the National Institutes of Health in which 20 patients with Raynaud’s phenomenon were trained on biofeedback. Except for one case, the remaining 19 patients stopped the onset of Raynaud’s phenomenon at 3.3 ° C. The response to hypothermia was near normal, and patients felt subjective, feeling relaxed, tense, easy to fall asleep, better able to adapt to a variety of settings and doing more in the open air or in other cold winters in winter. Patients have a primary or secondary Renault phenomenon, and confirmed by the typical three-color skin changes, that is, when the cold or emotional stress skin color sequence becomes pale, purple, flushing, cold skin temperature 3.3 ℃ in the skin quickly The patients were randomized into two groups of ten with another ten in the normal control group.The first group of patients measured the change in skin temperature with a thermistor every 15 seconds and labeled this with an instrument connected to an optical signal Change, temperature rise or changeless light signal
