Transcutaneous electrical nerve stimulation (TENS) therapy utilizes a small, battery-powered device to deliver low-voltage electrical currents to targeted nerves. Following surgical intervention for joint replacement, this therapy can be employed to manage postoperative pain. A typical application involves placing electrode pads near the surgical site, with the device controlling the intensity and frequency of the electrical pulses.
This non-invasive pain management technique offers a potential alternative or supplement to pharmacological interventions. It can assist patients in regaining mobility and improving overall comfort during the rehabilitation process. Historically, electrical stimulation for pain relief has been explored for centuries, with modern TENS therapy emerging in the latter half of the 20th century. The development of compact, portable devices has made this therapy increasingly accessible and practical for at-home use, particularly in postoperative care scenarios.
