Spinal Cord Stimulation Therapy for Hereditary Spastic Paraplegias Patients
Effects of Spinal Cord Stimulation Therapy on Motor Function and Gait in Patients With Pure Hereditary Spastic Paraplegias
調査の概要
詳細な説明
Pure hereditary spastic paraplegia is a heterogeneous group of genetic disorders characterized by degeneration of the corticospinal tracts, coursing with progressive weakness and spasticity of the lower limbs. The available anti spastic agents and surgical procedures involving anti-spastic systemic drugs, botulinum toxin, intrathecal baclofen, and even selective dorsal rhizotomy have not shown an improvement in muscle strength. Physical rehabilitation alone has shown positive results in short term, but this effect tends to fade away in few months.To date, there are no effective treatments for progressive deficits or disease-modifying therapy for Hereditary spastic paraplegia patients,
Spinal cord stimulation is a wellestablished therapy for the treatment of chronic neuropathic pain. Recently, some pilot studies demonstrated encouraging results of SCS in improving motor function. Patients severely affected by spinal cord injury experienced enhancements in leg movements and Parkinson's disease, primary progressive freezing of gait, and multiple system atrophy with predominant parkinsonism patients improved gait performance and freezing of gait after spinal cord stimulation by inducing changes in spinal and brain circuitry function. Some case studies suggest spinal cord stimulation may delay motor worsening and be innovative lines of research for the treatment of spastic paraplegia. However, evidence from larger numbers of subjects is still lacking. The objective of this study is to investigate the therapeutic effect and safety of spinal cord stimulation on motor function and gait in patients with pure hereditary spastic paraplegias
It's a single-center, prospective, open label clinical study with a 12 months follow- up period. The intended study population is individuals suffering from pure hereditary spastic paraplegia.Each participant will complete an enrollment/ screening/baseline visit, a spinal cord stimulation implant and activation visit, and a minimum of two follow-up visits, including visit at 3 months and the final study visit at 12months. The participants will proceed to implantation after satisfying implant inclusion and exclusion criteria. Paddle-shaped Spinal cord stimulation electrode with 16 contacts ((AdaptiveStim 39, 565; Medtronic, Minneapolis, USA) will be implanted into the epidural space at the thoracic levels ranging from T10 to T12. Electrode position will be verified by X-ray. The stimulators will be turned on within 1 month after electrode implantation surgery (slightly below sensory threshold). The stimulation parameters could vary freely, but medications will be kept constant during the study period. At the end of month 12, participants will enter the long-term follow-up in which medications and stimulation parameters could vary freely.
