本研究探讨了帕金森病（PK）患者体位摇摆的特征。我们检查了16例既往诊断为PK的患者。受试者站在稳定计上，睁开或闭上眼睛，记录身体重心的摆动1分钟。分析PK患者站立姿势时的摇摆模式。受试者共16例，其中2例为阳性症状（PK-P）， 6例（PK-Na）和8例（PK-Nb）为阴性症状。结果1)睁眼时，有向心型6例，左右型2例，弥漫型2例，移位型4例，多中心型2例。闭眼时，4个向心型、4个前后型、3个左右型、1个扩散型、2个移位型、2个多中心型。位移型和多中心型是PK中具有代表性的身体摇摆类型。2)考虑到睁眼和闭眼时身体摇摆的相似性，我们将PK中身体摇摆分为向心前后向型、左右扩散型、位移型和多中心型三组。3)考虑到症状分型与身体摇摆的关系，我们将PK-Na与移位型、多中心型、PK-Nb与左右型、弥漫型联系起来。结果表明，向心型和前向后型涉及体位固定和平衡障碍，左右型和弥漫型涉及扶正障碍，位移型和多中心型涉及震颤、运动障碍和体位固定和平衡障碍。
This study investigated the characteristics of postural sway in cases of Parkinson's diesease (PK). We examined 16 patients previously diagnosed with PK. The subjects stood on a stabilometer with their eyes open or closed, and the sway of the center of gravity of the body was recorded for one minute. The sway pattern during standing posture in PK patients was analyzed.The subjects consisted of 16 patients, including two with positive symptoms (PK-P), while six (PK-Na) and eight (PK-Nb) had negative symptoms.Results1) With eyes opened, the sway pattern was centripetal in six, right-left in two, diffuse in two, the displacement type in four and the multiple center type in two. With eyes closed, the sway pattern was centripetal in four, forward-backward in four, right-left in three, diffuse in one, the displacement type in two and the multiple center type in two. The displacement and multiple center types were representative of body sway in PK.2) Considering the similarities in body sway with eyes open and closed, we divided body sway in PK into three groups (centripetal and forward-backward type, right-left and diffuse type, displacement and multiple center type).3) Considering the relation between the classification by symptoms and body sway, we related PK-Na with displacement and multiple center type and PK-Nb with right-left and diffuse type.It was demonstrated that the centripetal and forward-backward type involved disorders in postural fixation and equilibrium, the right-left and diffuse type involved righting disorder, while the displacement and multiple center type involved tremor, akinesia and disorders in postural fixation and equilibrium.
