Six months post-surgery, with intensive physiotherapy and neurorehabilitation, Fidyka was beginning to notice gains in muscle mass and was able to tentatively take steps with the use of leg braces, parallel bars and a physiotherapist. Fidyka also recovered improved trunk stability, some voluntary movement in his lower extremities and partial recovery of superficial and deep sensation below his injury level. Diagnostic imaging suggests that with the cell transplant, the 8 mm gap in Fidyka’s spinal cord has repaired and regenerated (4).
