Clinical Trial Summary

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.

Eligibility

Inclusion Criteria:

• 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.)

Exclusion Criteria:

• 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);

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Pain as measured by the visual analog scale (VAS). Scores are recorded from 0 to10.	Scores are recorded from 0 to 10 with 0 being "no pain" and 10 being "worst pain."	Baseline, 5 minutes after intervention
Primary	Change in sensation measured by Electrical sensation detection threshold (EDT)	This is self-reported by the subjects as soon as they first sense the electrical current.	Baseline, 5 minutes after intervention
Primary	Change in pain measured by Electrical pain detection threshold (EPT)	This is self-reported by the subjects at the first sensation of pain.	Baseline, 5 minutes after intervention
Primary	Change in Heart Rate Variability (HRV) measured by electrocardiogram (ECG)	HRV is a measure of the variation in time between each heartbeat. We use HRV to identify the autonomic nervous system changes after intervention treatment.	Baseline, 5 minutes after intervention
