Abstract: 

Study investigated the relationships between clinical and biomechanical walking measures that may contribute to changes in daily stepping activity following physical interventions provided to participants with subacute stroke. The primary outcomes were short- and long-term changes in daily stepping activity, evaluated following up to 40 training sessions (POST) and at 2 to 6 months follow-up (F/U). Thirty-nine participants were categorized into three groups: (1) responders/retainers who increased daily stepping >500 steps per day at POST without decreases in stepping at F/U, (2) responders/non-retainers who increased stepping at POST but declined >500 steps per day at F/U, and (3) non-responders who did not change daily stepping from baseline testing (BSL). Gait kinematics and kinetics were evaluated during graded treadmill assessments at BSL and POST. Clinical measures of gait speed, timed walking distance, balance, and balance confidence were measured at BSL, POST and F/U. Between-group comparisons and regression analyses were conducted to predict stepping activity from BSL and POST measurements. Baseline and changes in clinical measures of walking demonstrated selective associations with stepping, although kinematic measures appeared to better discriminate responders. Specific measures suggest greater paretic versus non-paretic kinematic changes in responders with training, although greater non-paretic changes predicted greater gains (i.e., smaller declines) in stepping in retainers at F/U. No kinetic variables were primary predictors of changes in stepping activity at POST or F/U. The combined findings indicate that specific biomechanical assessments may help differentiate changes in daily stepping activity post-stroke.
