Although the use of treadmill , partial weight-bearing and robotic orthotics are essential in the training of locomotion in SCI patients , little has been published about the progress of the training, clinical decision making and evaluation of progress.[16] Most of the studies on the subject provide only very general criteria to optimize treatment (modifying body weight support and speed training), providing insufficient evidence to guide the training progression in parameters such as training frequency, speed and optimal duration of treatment.
