Standing balance was evaluated in ten subjects with hemiplegia using a sensory organization balance test (SOT). The SOT is a timed balance test which evaluates somatosensory, visual, and vestibular function for maintenance of upright posture. The duration of bilateral stance was assessed using combinations of three visual and two support surface conditions. Stance time was measured with eyes open, eyes closed, and with each patient wearing a visual dome to produce inaccurate visual information. The support surface conditions involved stance on a hard flat floor followed by attempted stance on a compliant foam surface. Visual deprivation or visual conflict conditions did not cause a loss of balance when stance was performed on a stable surface. However, a lower stance duration was found when patients stood on a compliant surface (p less than .05). Visual compensation was evident during the compliant-surface condition because stance duration showed the greatest reductions with eyes closed and with the visual dome. These findings suggest that the ability to integrate somatosensory information from the lower extremities for balance is compromised after cerebrovascular disease. The implications for diagnosing the specific cause of balance dysfunction and for developing sensory-specific therapeutic interventions are discussed.
使用感觉统合平衡测试（SOT）对10名偏瘫患者的站立平衡进行了评估。SOT是一种定时平衡测试，用于评估维持直立姿势的体感、视觉和前庭功能。使用三种视觉和两种支撑面条件的组合来评估双侧站立的持续时间。在睁眼、闭眼以及每位患者佩戴视觉圆顶以产生不准确视觉信息的情况下测量站立时间。支撑面条件包括在坚硬平坦的地面上站立，然后尝试在柔软的泡沫表面上站立。当在稳定表面上进行站立时，视觉剥夺或视觉冲突条件不会导致平衡丧失。然而，当患者站在柔软表面上时，站立持续时间较短（p小于0.05）。在柔软表面条件下，视觉补偿很明显，因为站立持续时间在闭眼和佩戴视觉圆顶时减少最多。这些发现表明，脑血管疾病后，整合来自下肢的体感信息以维持平衡的能力受到损害。讨论了对诊断平衡功能障碍特定原因以及制定特定感觉治疗干预措施的意义。
