In this study the sway of the center of gravity was observed in patients with spinal canal stenosis, in order to observe the movement of the center of the gravity after the onset of claudication. In normal subjects the sway of the center of gravity was restricted to a small area, but in patients with spinal stenosis, the center of gravity was diverted to the left or right side. With claudication, the center of gravity moved forward. Following several rest periods, the center of gravity returned to the initial area. The time required to return to the initial area was longer than for a patient's subjective recovery from the symptoms.
在本研究中，观察了椎管狭窄患者重心的摆动情况，以观察间歇性跛行发作后重心的移动情况。在正常受试者中，重心的摆动局限于一个小区域，但在椎管狭窄患者中，重心偏向左侧或右侧。发生间歇性跛行时，重心向前移动。经过几次休息后，重心回到初始区域。回到初始区域所需的时间比患者从症状中主观恢复所需的时间更长。
