Two patients with cervical spinal cord lesions were treated for postural hypotension using auditory and visual feedback for voluntary increases in blood pressure. Following initial measures of blood pressure, feedback was delivered for systolic increases above baseline. Within several weeks, both patients learned to increase their pressure markedly from the start of training sessions to their conclusion. The patients' legs were progressively lowered during and at the end of training sessions without significant blood pressure decreases. Long-term follow-up indicated that they were able to maintain the learned increases in blood pressure despite adverse medical conditions. It is suggested that central nervous system damage disrupts homeostatic regulation, permitting greater voluntary control through biofeedback as a new feedback loop. Motivation is also considered an important variable for success.
两名患有颈脊髓损伤的患者接受了针对体位性低血压的治疗，通过听觉和视觉反馈来自主提高血压。在进行初始血压测量后，当收缩压高于基线时给予反馈。几周内，两名患者都学会了从训练开始到结束显著提高血压。在训练过程中和结束时，患者的双腿逐渐放下，血压没有明显下降。长期随访表明，尽管存在不良医疗状况，他们仍能够维持通过学习获得的血压升高。研究表明，中枢神经系统损伤会破坏体内平衡调节，从而通过生物反馈作为一种新的反馈回路实现更大程度的自主控制。动机也被认为是成功的一个重要变量。
