Purpose
This two cases study was to investigate the effect of exoskeleton robot training with ExoAtlet on the gait for establishing the application method and feasting in incomplete spinal cord Injury patients
Methods
Exoskeleton robot training with ExoAtlet was applied to two selected male subjects with incomplete spinal cord Injury(S1: Thoracic 12 injury, S2: Lumbar 1 injury) who had legs with asymmetry motor and sensory conditions, and gradually increased the velocity distance, stride, height of foot and distance up to self-gait of 100 m without assistance. The foot pressure was measured during each session using foot pressure analyzer for evaluating the gait pattern. After completing the training, the ExoAtlet 's usability was assessed using the 10 satisfaction questionnaires.
Results
The subject1 was able to gait up to 60 m without assistance at the 6th training, and was able to gait 100 m without assistance at the 13th training. Subject2 was able to gait up to 60 m without assistance at the 9th training and was able to gait up to 100 m without assistance at the 11th training. At standing and gait, the subject1 with below Fair grade (Manual Muscle Test, MMT) of both leg was higher weakness leg more than strong leg on vertical ground reaction force and, subject2 with above Fair grade (MMT) of both leg was higher strong leg more than weakness leg. And the weight support and vertical reaction force were similar between both legs in subject1, but were difference between both legs in subject2.
Conclusions
Therefore, current exoskeleton robot training with ExoAtlet was showed various abnormal gait pattern and individually different adaptability of robot motion according to the physical condition of the patient due to adjust the motion of the robot. In the future, exoskeleton robot with ExoAtlet need to will be improve and customize for patient's improving quality of life.
