• Trunk performance after stroke was measured using the Trunk Impairment Scale.
• Quantitative gait characteristics in stroke were assessed by trunk accelerometry.
• Stroke patients showed relatively irregular and unsmooth walking patterns.
• Trunk control after stroke was related with accelerometry-based gait characteristics.
Trunk control plays an important role in movement control and postural balance during functional activities. The purpose of this study was to investigate the association of trunk control early after stroke with mobility performance and quantitative gait characteristics derived from trunk accelerations. Fifteen patients with hemiparesis following stroke (median age, 61 years [range, 56–78 years]; median time since stroke, 9 days [range, 7–15 days]) participated in this cross-sectional observational study. Subjects were evaluated using the Trunk Impairment Scale (TIS), the short-form of the Berg Balance Scale (SF-BBS), an isometric knee extension strength test, the Timed Up and Go test (TUG), and a timed walking test. The linear acceleration of the lower trunk was recorded along the 3 axes during walking and quantified using the autocorrelation coefficient and harmonic ratio to assess the variability and smoothness of upper-body movement. The TIS total score had a significant correlation with TUG time. The coordination subscale score of the TIS was significantly correlated with TUG time, walking speed, and accelerometry variables in univariate analysis. The TIS coordination subscale score was significantly related to accelerometry variables in the partial correlation analysis adjusted for SF-BBS score and knee extension strength on the paretic and nonparetic side. These results indicate that trunk motor impairment after stroke is closely associated with poor mobility performance and trunk instability in gait. These findings support intensive rehabilitation treatment targeting trunk control to regain better mobility and stable gait in patients early after stroke.
