脳卒中片麻痺者の歩行に対する主観的評価と歩容の関連性の検討

Abstract

[Objectives] Subjective evaluation of gait is related to post-stroke activity and participation; however, its relationship with gait performance is unclear. This study aimed to investigate the relationship between subjective evaluation of gait and gait performance in individuals with stroke. [Methods] Twenty-two participants with stroke were assessed for subjective evaluation of gait, physical function, and gait function at discharge. The participants’ physical function was assessed using the Fugl-Meyer assessment and the Berg Balance Scale. Gait performance was assessed through gait speed, joint motion, root mean square, gait regularity, and gait symmetry using magnetic inertial measurement units. Correlations between the participants’ subjective evaluation of gait and each indicator were analyzed. [Results] Subjective evaluation of gait difficulty exhibited a significant negative correlation with the hip extension angle on the affected side (rs＝－0.530, p＝0.011) and gait regularity (mediolateral, anteroposterior, and vertical) (rs＝－0.498 to －0.451, p＜0.050). Subjective evaluation of balance during gait was positively correlated with Fugl-Meyer assessment (rs＝0.444, p＝0.038) and negatively correlated with anteroposterior (rs＝－0.444, p＝0.038), and vertical (rs＝－0.592, p＝0.004) root mean square. [Conclusion] Subjective evaluation of gait difficulty may be influenced by perceived gait stability. Subjective evaluation of balance during gait indicated that post-stroke patients with less trunk sway during gait may be aware of wobbling.
