This study aims to verify whether high-intensity pulsed electromagnetic fields (HI-PEMF) can be effectively applied to postoperative total hip arthroplasty patients. Using pain and function as the primary assessment indicators, the study explores the effects of HI-PEMF on postoperative total hip arthroplasty to confirm its effectiveness in relieving pain and improving daily living functions. Simultaneously, it combines physical therapy with exercise training to simulate a clinical environment, comprehensively understanding the feasibility of future clinical applications of magnetic field therapy. It is hoped that by exploring the potential benefits of magnetic field intervention in improving the postoperative condition of these high-needs patients, new clinical evidence can be provided for postoperative management.

High-Intensity Pulsed Electromagnetic Field（HI-PEMF)
DeviceHigh-Intensity Pulsed Electromagnetic Field (HI-PEMF) is a non-invasive, contactless technology delivering strong magnetic pulses (up to 3 T or more) to biological tissue. It serves as a superior alternative to traditional electropermeabilization by altering cell membrane permeability.
