Ultrasound imaging has the advantages of high accuracy, dynamic observation, visualization and no radiation exposure. Ultrasound-guided injection therapy can accurately inject drugs into painful lesions or spastic muscles, significantly improving the efficacy of treatment and reducing the number of adverse events, such as accidental entry of drugs into blood vessels or damage to nerves. Our department has carried out ultrasound-guided intra-articular injections, nerve blocks, myofascial pain trigger point injections, epidural injections, etc., as well as botulinum toxin injections for spasticity and spasticity for many years, and has a wealth of clinical experience.
