简要总结
The purpose of this study is to compare the effectiveness of innovative intervention of breathing controlled electrical stimulation (BreEStim) and conventional electrical stimulation (EStim) in management of neuropathic phantom limb pain in patients after limb amputation.

入选标准
- •has phantom limb pain (PLP) after amputation of one limb, upper or lower limb;
- •has chronic pain, >3 months;
- •is stable on oral pain medications at least two weeks. (patients are allowed to continue their pain medications, i.e., no change in pain medications.)
排除标准
- •currently adjusting oral pain medications for their PLP;
- •has pain, but not PLP (e.g., from inflammation at the incision wound of the residual limb);
- •has a pacemaker, or other metal and/or implanted devices;
- •has cognitive impairment from brain injury or are not able to follow commands, or to give consent;
- •has amputation in multiple limbs;
- •have asthma or other pulmonary diseases;

- •have preexisting psychiatric disorders;
- •alcohol or drug abuse;
- •have a history of seizures/Epilepsy, or taking benzodiazepines, anticonvulsants, and antidepressants.
结局指标
主要结局
Change in Pain Level as Measured by the Visual Analog Scale (VAS).
时间窗: Baseline, 10 minutes after intervention
VAS scores are recorded from 0 to 10 with 0 being "no pain" and 10 being "worst pain", a higher score indicating a higher level of pain. Change is reported as \[(VAS score at baseline) - (VAS Score 10 minutes after intervention)\] - a positive value indicates that the score (and pain level) decreased
次要结局
- Change in Sensation Threshold on Amputated Limb Measured by Electrical Sensation Threshold (EST)(Baseline, 5 minutes after intervention)
- Change in Pain Threshold on Amputated Limb Measured by Electrical Pain Threshold (EPT)(Baseline, 5 minutes after intervention)
