This is absolutely fantastic and its a great step in the right direction but we are still years if not decades away from being able to circumvent spinal lesions in humans. One of the major problems with human spinal lesions is the loss of control of the trunk of the body (ie the core). Humans have dozens of muscle groups that control balance and posture through minute movements. Without fine grain control over these muscles balance is going to be extremely difficult.
