Spinal cord injury (SCI) often results in complete or partial paralysis below the level of lesion, having a profound physical, psychological and socioeconomic impact on the affected person's life. Between the different approaches for the rehabilitation of SCI, we can find robot therapy. Robot-assisted gait training has emerged as a promising therapy for improving walking ability, balance and motor function in neurological patients. The underlying principle of this therapy is based on the execution of repetitive and task-specific training able to generate appropriate afferent inputs, activating the central pattern generators in the lumbosacral spinal cord. Another novel therapy is the use of transcutaneous spinal cord stimulation (tSCS), applied through self-adhesive electrodes in the skin. tSCS activates similar mechanisms than epidural stimulation and is able to stimulate the spinal locomotor circuits in SCI patients. It allows the activation of rhythmic, flexo-extension movements in the paralyzed lower limbs.~The aim of this study is to analyze the feasibility, safety and efectiveness of a program of 20 sessions of 30 Hz-tSCS applied over T11-12 intervertebral space combined with Lokomat training in patients with incomplete SCI.
Lumbosacral spinal stimulation activates the neural network involved in the control of locomotion at the spinal level. However, its effects are limited to the production of robust rhythmic patterns of alternating movement, being currently in the absence of therapeutic value. On the other hand, the use of robotic technology for gait rehabilitation has experienced significant growth during the last years and its clinical efficacy is similar to others traditional interventions.
