About this study
Official title: Effects of Additional High-Intensity Pulsed Electromagnetic Field (HI-PEMF) Therapy on Pain and Physical Function After Total Hip Replacement: A Randomized Controlled Trial
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
High-Intensity Pulsed Electromagnetic Field（HI-PEMF)Device
High-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.
Post Operative exerciseOther
Post operative program exercise for THR
| Study group | Role | What they receive |
|---|---|---|
| Arm 1:HI-PEMF | Experimental | HI-PEMF Receives: Device: High-Intensity Pulsed Electromagnetic Field（HI-PEMF); Other: Post Operative exercise |
| Arm 2 :exercise | Active comparator | Not described Receives: Other: Post Operative exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)
This scale can measure THR patient pain and function.The standard WOMAC scale (using a 0-4 Likert scale for each of the 24 questions) ranges from 0 to 96.
Measured: 1-month
