Summary

Shoulder pain is a common problem after certain types of lung surgery called video-assisted thoracoscopic surgery (VATS). This study examines whether a treatment called transcutaneous electrical acupoint stimulation (TEAS) can help reduce this pain. TEAS is a non-invasive technique that uses mild electrical stimulation at specific points on the body.Patients who are having VATS lung surgery will be randomly assigned to either receive TEAS before surgery or standard care. Researchers will measure how much shoulder pain patients experience and compare the two groups.The goal is to see if TEAS can help patients feel less pain and recover better after this type of lung surgery.

Conditions

  • Ipsilateral Shoulder Pain
  • Video-Assisted Thoracoscopic Surgery

Interventions

DEVICE

TEAS

TEAS is a non-invasive transcutaneous electrical stimulation procedure. The TEAS device delivers a sparse-dense waveform. The current intensity is set within a range of 2-20 mA. The intervention administrator adjusts the current intensity within the pre-defined safety limits according to patient tolerance to maintain a mild soreness/"deqi" sensation. TEAS will be delivered twice for 30 minutes each: in the evening the day before surgery and before anesthesia induction on the day of surgery. Electrodes will be applied at LI4 (Hegu), PC6 (Neiguan), SJ14 (Jianliao), and LI15 (Jianyu).

DEVICE

Sham TEAS

he sham procedure is a sensory-matched inactive stimulation. During the first 30 seconds, identical stimulation parameters to the active TEAS group are delivered using a sparse-dense waveform with instantaneous stimulation (5-10 mA) to produce a mild tingling sensation matched to the active arm. After 30 seconds, the device stops delivering effective electrical current while maintaining normal indicator lights and the operation interface. Sham stimulation is administered twice: in the evening the day before surgery and before anesthesia induction on the day of surgery, for 30 minutes each time. Electrode placement is identical to the TEAS arm at LI4 (Hegu), PC6 (Neiguan), SJ14 (Jianliao), and LI15 (Jianyu).
