Lumbar spine physical therapy mainly plays the role of activating blood circulation and promoting the remission of inflammatory reactions. When the lumbar spine produces disease, doing lumbar microwave physiotherapy can reduce lumbar pain and swelling, reduce intertissue fluid exudation from the soft tissues of the lumbar region, thus improving local blood circulation and reducing soft tissue swelling, as well as significantly improving the function of the lumbar region. For ligamentitis of the lumbar region, such as supraspinous ligamentitis, paraspinous ligamentitis, as well as lumbar muscle strain, lumbar disc herniation and other diseases have a relatively good therapeutic effect. However, lumbar spine physiotherapy cannot be used as the main treatment plan, but it works relatively well as an adjunctive treatment.
