Recovery of Over-Ground Walking after Chronic Motor Complete Spinal Cord Injury
Open accessAbstract
Summ a r yPersons with motor complete spinal cord injury, signifying no voluntary movement or sphincter function below the level of injury but including retention of some sensation, do not recover independent walking.We tested intense locomotor treadmill training with weight support and simultaneous spinal cord epidural stimulation in four patients 2.5 to 3.3 years after traumatic spinal injury and after failure to improve with locomotor training alone.Two patients, one with damage to the mid-cervical region and one with damage to the high-thoracic region, achieved over-ground walking (not on a treadmill) after 278 sessions of epidural stimulation and gait training over a period of 85 weeks and 81 sessions over a period of 15 weeks, respectively, and all four achieved independent standing and trunk stability.One patient had a hip fracture during training.(Funded by the Leona M. and Harry B. Helmsley Charitable Trust and others; ClinicalTrials.govnumber, NCT02339233.)T here are estimated to be 1,275,000 persons with paralysis from spinal cord injury in the United States. 1 These patients indicate in surveys that walking and standing are highly desirable goals. 2 We have previously shown that epidural stimulation of the spinal cord and simultaneous intense rehabilitation may allow the restoration of some volitional movement below the level of spinal injury 3,4 and may result in the ability to stand independently.5,6 We report here recovery of independent walking over ground, not on a treadmill, in two of four patients with motor complete paralysis, with the use of a program that combines customized epidural spinal cord stimulation and intense training in standing and stepping.The study was approved by the institutional review board at the University of Louisville and was conducted in accordance with the Declaration of Helsinki.All the patients provided written informed consent.All the authors vouch for the completeness and accuracy of the data and the reporting of adverse events and for the adherence of the study to the protocol, available with the full text of this article at NEJM.org.Medtronic provided the epidural electrode arrays, neurostimulators, programming devices, and recharging units to the Kentucky Spinal Cord Injury Research Center at the University of Louisville.There was no other industry involvement, and no funds were given by Medtronic to the institution, investigators, or research participants.The delay between active intervention for the first patient (November 11, 2014) and registration of the study (January 12, 2015) is explained in the Supplementary Appendix, available at NEJM.org.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
