Abstract

Introduction: Body lateropulsion (BL) is an active lateral tilt of the body during standing or walking that is thought to be affected by a lesion of the vestibulospinal tract (VST) and the subjective visual vertical (SVV) tilt. Interventions for BL have not been established.

Objective: We examined the effects of postural-control training with different sensory reweighting on standing postural control in a patient with BL.

Methods: The patient had BL to the left when standing or walking due to a left-side medullary and cerebellar infarct. This study was a single-subject A-B design with follow-up: Phase A was postural-control training with visual feedback; phase B provided reweighting plantar somatosensory information. Postural control, VST excitability, and SVV were measured.

Results: At baseline and phase A, the patient could not stand with eyes-closed on a rubber mat, but became able to stand in phase B. The mediolateral center of pressure (COP) position did not change significantly, but the COP velocity decreased significantly during phase B and the follow-up on the firm surface. VST excitability was lower on the BL versus the non-BL side, and the SVV deviated to the right throughout the study.

Conclusion: Postural-control training with reweighting somatosensory information might improve postural control in a patient with BL.

不同感觉重加权的姿势控制训练对一名身体后倾患者的影响：一项单一受试者设计研究。

简介：身体侧倾（BL）是一种在站立或行走过程中身体的主动侧倾，被认为受到前庭脊髓束（VST）损伤和主观视觉垂直（SVV）倾斜的影响。尚未制定BL干预措施。目的：我们研究了不同感觉重加权的姿势控制训练对BL患者站立姿势控制的影响。方法：该患者在站立或行走时因左侧髓质和小脑梗死而出现左侧BL。本研究为单受试者a-B设计，并进行随访：a阶段为视觉反馈的姿势控制训练；B期提供了足底体感信息的重新加权。测量体位控制、VST兴奋性和SVV。结果：在基线和A期，患者不能闭着眼睛站在橡胶垫上，但在B期可以站立。中外侧压力中心（COP）位置没有显著变化，但COP速度在B期和在坚硬表面上随访期间显著下降。与非BL侧相比，BL侧的VST兴奋性较低，并且在整个研究过程中SVV向右偏移。结论：体感信息重加权的体位控制训练可以改善BL患者的体位控制。
