A 18-yeаr-оld bоy recently suffered а SCI frоm а snowboarding accident. Upon assessment, it was determined that the injury was at the T10 level, as he had some motor function in his legs (i.e. moving toes and flexing knees while lying down). However, there is limited muscle strength and they cannot move against gravity, but some sensation was preserved below the injury level. Which scale will give therapists the most accurate understanding of the level of impairment for a spinal cord injury patient?
