Study on the Effect of Electronic Moxibustion on Non-Specific Low Back Pain in Young Adults

This is an interventional clinical study. A total of 90 subjects aged 18 to 40 years are planned to be recruited. The subjects have low back pain that affects daily work and life, resulting in reduced exercise tolerance or aggravated pain after exercise, while retaining basic living ability and being capable of performing partial activities; their VAS scores range from 4 to 6. At baseline, the duration of subjects' low back pain and disability index will be recorded, along with muscle stiffness and electroencephalogram findings. Afterwards, electronic moxibustion treatment will be administered for 4 weeks. Subjects will be randomly divided into a treatment group and a control group with equal numbers of participants. The treatment group will use a Wenyang instrument with a rated frequency of 50 Hz, with the temperature set between 40℃ and 60℃ based on subjects' comfort level. Each treatment session lasts 30 to 60 minutes, 5 times per week for 4 weeks. The Wenyang instrument is used by subjects at home, with researchers providing remote guidance and supervision via voice or video. Subjects will check in and upload records after each use of electronic moxibustion, which will be documented by researchers. If subjects suffer from unbearable low back pain during the study, they may take oral ibuprofen or celecoxib for pain relief. The dosage and administration time will be recorded, and check-in and upload will be completed after each dose of analgesics for researchers' documentation. Subjects in the control group will take oral ibuprofen or celecoxib for pain relief as needed (i.e., when they feel pain). The dosage and administration time will be recorded with check-in and upload. After 4 weeks of intervention, the two groups will be compared in terms of the number of days of analgesic use or total consumed dosage, as well as changes in VAS scores, disability index, muscle stiffness and electroencephalogram findings.
