Can gait outcomes be predicted early after a stroke?

PURPOSE: To determine the ability of clinical measures collected within 72 hours of neurological insult to predict independent gait 6 and 12 months after a stroke.

METHODS

Patients with a confirmed stroke diagnosis were eligible for inclusion in this prospective cohort study. Sitting balance, National Institutes of Health Stroke Scale (NIHSS) motor leg, NIHSS motor arm, and Motricity Index (MI) were measured within 72 hours post-stroke. Follow-up assessments were conducted at 6 and 12 months post-stroke to measure gait recovery.

RESULTS

A total of 78 patients were included at baseline for analysis. At 6 and 12 months, 38% (n = 38) and 35% (n = 42) of patients used a gait aid, and 80% and 87% were independently ambulant, respectively. Sitting balance, NIHSS motor leg, and NIHSS motor arm were not significantly associated with ambulation at 6 or 12 months or with the use of a gait aid. Thrombolysis was significantly associated with independent outdoors ambulation at 6 months (p = .011). A worse MI score was significantly associated with a higher number of falls at 6 months (p < .010) but not with the need for a gait aid. The number of falls at 6 months was independently predicted by urinary incontinence post-stroke (p < .001), NIHSS leg score (p < .005), and depression and anxiety while in acute care (p < .005).

CONCLUSIONS

Clinical bedside assessments may be less important in predicting safe, independent gait than previously thought. Urinary incontinence and poor mental health should be addressed in the hospital. Increased utilization of reperfusion techniques may alter functional recovery patterns.
