Effect of Patient-Controlled Transcutaneous Electrical Acupoint Stimulation on Quality of Life in Chronic Cancer Pain

Summary

This study aims to objectively evaluate the effect of Patient-Controlled Transcutaneous Electrical Acupoint Stimulation (PC-TEAS) on improving the quality of life in patients with chronic cancer pain, thereby providing evidence-based medical support for its efficacy and offering practical basis for patients to achieve home-based auxiliary treatment based on their own needs. Furthermore, by observing and comparing changes in indicators such as pain-related scores, analgesic consumption, emotional scores, spontaneous bowel movements, and adverse events, this research will comprehensively assess the advantages of PC-TEAS in the management of chronic cancer pain and explore other potential benefits of this intervention for patients.
