Inclusion criteria
Inclusion criteria: 1. Having knee pain for more than 6 months with at least one of the following three conditions - Aged over 50 years - Morning knee stiffness less than 30 minutes - Crepitus on knee motion 2. Aged over 50 years 3. Radiographic assessment of the knee shows osteoarthritic changes consistent with Kellgren and Lawrence classification stages 2 to 4 4. Having knee pain score of greater than or equal to 4 on the Visual Analog Scale (VAS) score while standing or walking, if bilateral knee pain was presented, the more painful side must have a VAS score of greater than or equal to 4 while standing or walking, and the less painful side must have a VAS score of less than 4 while standing or walking. 5. No prior history of receiving a Peripheral Magnetic Stimulation (PMS) treatment for the knee 6. Participants consent to participate in the research by signing. 7. If the participant was already wearing a knee support as part of their physician-prescribed treatment, which is considered a standard treatment for pain relief, they could continue wearing it during participating in the research study, since the use of a spiral knee brace is the standard conservative treatment according to the clinical practice guidelines for the treatment of knee osteoarthritis (if applicable).

Had severe chronic underlying diseases, such as cancer or epilepsy. 5. Had neurological disorders. 6. Had uncontrolled hypertension (systolic blood pressure > 180 mmHg or diastolic blood pressure > 100 mmHg). 7. Pregnancy or breastfeeding 8. Had received a steroid injection into the knee joint within the past 6 months. 9. Had received intraarticular hyaluronic acid injections into the knee within the past 6 months. 10. Had a cardiac pacemaker, cochlear implant, or Ventriculoperitoneal (VP) shunt. 11. Had foreign metallic objects implanted in the body, such as bullets. 12. Had declined or withdrawn from participation in the research study. 13. Unable to provide information to complete the questionnaire.
