Although we have shown that the initial ASIA grade of SCI is related to walking after NTSCI, a notable amount of the variation in walking ability remains unexplained.Larger studies are required to explore other factors that may influence walking outcomes such as body anthropometry, comorbidities and patterns of recovery in muscle strength. In addition, given the relatively poor ambulation outcomes of NTSCI patients at rehabilitation discharge compared with
community-living age-matched norms, research exploring the potential benefits of treatments such as functional electrical stimulation and partial body-weight-supported treadmill training on gait outcomes is warranted.
