**2. Gait rehabilitation interventions following spinal cord injury**

Until now, many therapeutic strategies have been developed for promoting locomotor activity of SCI subjects ranged from those that compensate for weakened or lost function (e.g. orthotic gait training) to strategies based on the concepts of central nervous system (CNS) plasticity (e.g. Erigo therapy and body weight–supported tread mill training) [15, 16]. Strategies that are based on the concept of CNS plasticity have shown improvement and enhancement in walking ability of SCI subjects through implementing the task-specific sensory input and repetitive and intensive gait therapy [17, 18]. These strategies will be explained as following.
