著者：＊Mitsutake T, Sakamoto M, Ueta K, Horikawa E. 題名：Standing postural stability during galvanic vestibular stimulation is associated with the motor function of the hemiplegic lower extremity post-stroke発表情報：Top Stroke Rehabil 巻: 27 号: 2 ページ: 110-117キーワード：概要：Background: The vestibular system is profoundly involved in standing postural stability. Patients with post-stroke hemiparesis have poor postural control function; nevertheless, it is unclear as to how the vestibular system affects postural control after stroke.Objectives: The purpose of this study was to quantitatively evaluate the relationship between galvanic whole-body sway responses and motor function of the hemiplegic lower extremity post-stroke.Methods: Thirty stroke patients and 49 healthy controls underwent standing body sway tests to examine postural control function during vestibular stimulation. Postural stabilization was measured using a C7-mounted accelerometer during galvanic vestibular stimulation. Postural stability was assessed during stimulation while quietly standing with eyes closed. For the stroke group, lower extremity function was measured using the Fugl-Meyer Assessment scale (FMA-LE).Results: The standing body sway test scores during stimulation were lower in the stroke group than the control group (p = .010). In the stroke group, correlation analysis demonstrated that the standing body sway response score was significantly associated with the FMA-LE (r = 0.374, p = .021).Conclusions: Motor dysfunction directly causes standing postural instability during vestibular stimulation, even though sensory information suggests normal peripheral vestibular function. Therefore, motor dysfunction of the hemiplegic lower extremity might lead to inhibition of normal standing postural stability.抄録：英語フィールド
