Spastic cerebral palsy is the most common form of cerebral palsy and currently consists of three steps in terms of treatment mechanism: release of spasticity, correction of deformity and rehabilitation training. FSPR is an intraoperative monitoring by multi-conductor electrophysiological technology, which determines the proportion of spinal nerve posterior roots to be removed, making the scope and proportion of sensory nerve removal more scientific and objective. The muscle tone of the patient is adjusted comprehensively, so that the muscle tone of the spastic muscles is as close to normal as possible. The muscle spasm in cerebral palsy patients is not limited to a single muscle, but often manifests as spasm of multiple muscles or muscle groups, and this surgery can achieve the effect of comprehensive adjustment of muscle tone, and it can solve the pain of muscle spasm of patients in a long-term, stable and thorough way, providing the prerequisite for the maximum recovery of their motor functions. FSPR only selectively blocks part of the posterior nerve root fibers, without affecting the anterior nerve roots that govern muscle movement and motor function. The specific site of surgery can depend on the patient’s specific condition: surgery in the lumbar spine can address lower extremity spasticity, and surgery in the cervical spine can address upper extremity spasticity. The efficacy of surgery in the lumbar and lumbosacral regions is basically the same, and currently the main choice is to operate on the bony tail of the lumbosacral region, which reduces the risk of surgery and complications. Before each surgery, a set of scientific and reasonable individualized treatment plan including preoperative evaluation and selection of appropriate methods will be made for different conditions of patients, and long-term formal rehabilitation training should also be adhered to after the implementation of FSPR, so as to ensure the rehabilitation efficacy. In addition, some patients should also undergo a second stage of cerebral palsy surgery (i.e., muscle strength and tone adjustment) after FSPR, such as corrective treatment for deformities such as scissor gait and clubfoot.
