What does this procedure involve?

The treatment consists of four intrathecal injections of umbilical cord-derived mesenchymal stem cells (UC-MSCs) administered via lumbar puncture, spaced two weeks apart over an eight-week period. Each injection delivers stem cells directly into the cerebrospinal fluid, allowing them to target the central nervous system. Patients also undergo daily physical therapy to support motor function and rehabilitation. The entire protocol is performed on an outpatient basis, with each session lasting about 30–60 minutes.
