Postural steadiness while standing is impaired in individuals with spinal cord injury (SCI) and could be potentially associated with increased reliance on visual inputs. The purpose of this study was to compare individuals with SCI and able-bodied participants on their use of visual inputs to maintain standing postural steadiness. Another aim was to quantify the association between visual contribution to achieve postural steadiness and a clinical balance scale. ⋯ The Romberg ratios (eyes open/eyes closed) for COP MV and SA were significantly higher for individuals with SCI, indicating a higher contribution of visual inputs for postural steadiness in that population. Romberg ratios for RMS and SA were significantly associated with the Mini-BESTest. This study highlights the contribution of visual inputs in individuals with SCI when maintaining quasi-static standing posture.

Our previous study showed that 6 months after total hip arthroplasty (THA) or total knee arthroplasty (TKA), patients reported having less difficulty with daily activities, showed better functional capacity, and performed activities in their natural environment faster compared to preoperatively. However, their actual daily activity level was not significantly improved. Six months is a rather short follow-up period and the discrepancy in recovery among different aspects of functioning might be explained by this limited duration of follow-up. ⋯ However, the patients continued to improve in other aspects of physical functioning. In conclusion, 4-year post-surgery patients continued to improve on perceived physical functioning, capacity, and performance of activities in daily life. However, even in this relatively healthy study population, patients did not adopt a more active lifestyle 4 years after surgery.
