Effects of Additional High-Intensity Pulsed Electromagnetic Field (HI-PEMF) Therapy on Pain and Physical Function After Total Hip Replacement

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.

Inclusion Criteria:

A. Age 18 years or older.

B. Patients who have undergone primary unilateral total hip arthroplasty due to hip osteoarthritis.

C. Patients who, after postoperative evaluation by their surgeon, are advised to bear full weight within their tolerance.

Exclusion Criteria:

A. Patients who have not undergone primary hip arthroplasty.

B. Patients who are advised by their doctor to maintain non-weight-bearing or partial weight-bearing on the affected or unaffected side.

C. History of neurological deficits (e.g., sensory abnormalities, stroke, spinal cord injury, Parkinson's disease, multiple sclerosis).

D. Mini-Mental State Examination (MMSE) < 24 (mild cognitive impairment).

E. Berger's Balance Scale (BBS) < 40 (higher risk of falls).

F. Sensory abnormalities.

G. Before or after this exercise training, if pain in other areas (e.g., degenerative pain in the knee or spine) prevents movement, or if the hip joint still experiences pain on a Visual Analogue Scale (VAS) score of 4 or higher even after taking pain medication.

H. Known malignancy.

I. Schizophrenia, bipolar disorder, or substance addiction (e.g., alcohol, drug).

J. Pregnant woman.

K. Individuals with implanted stents, pacemakers, or those requiring treatment for arrhythmia.

L. Wearing a hearing aid.
