The combination of lumbosacral spinal cord epidural stimulation and stand training is used to promote the recovery of standing after severe spinal cord injury. Epidural stimulation parameters are tailored for each research participant with the goal of facilitating the generation of continuous activation patterns of the lower limb muscles in response to weight bearing-related sensory information. Stand training is generally performed overground with different devices (i.e. a custom-built standing apparatus, walkers, and others) that can be used by the participant for balance assistance. Manual assistance for facilitating knee, hip, and trunk extension is provided by trainers only when needed. During stand training, both stable standing and dynamic tasks that involve body weight shifting and upper limbs movement are practiced.
