在7例经神经传导研究证实的周围神经病变（PN）老年患者和7例神经传导功能正常的年龄和性别匹配(C)对照中，采用伺服控制足台量化直立站立时感知踝关节内翻和外翻运动的阈值。在75%的成功率（TH75）下，PN组感知踝关节旋转的存在和方向的阈值（平均[SD] 1.37[1.74]度）比C组（0.3[0.17]度）大3.6倍（p = 0.0026）。两组的内翻锐度约为外翻锐度的两倍，PN组单足站姿的本体感觉锐度优于双足站姿，而C组无此差异。除一例外，在坐姿下进行的PN组踝关节本体感觉的半定量临床试验未能显示出与对照组的显著差异；在老年人群中，PN与踝关节本体感觉缺陷有关，理论上已知这种缺陷会阻碍单足平衡的维持。值得注意的是，这些缺陷与临床上可证明的脚趾位置感丧失有关，而与脚踝无关。(C) 1995年由美国康复医学大会和美国物理医学与康复学会颁发
A servo-controlled foot platform was used to quantify, in upright stance, the thresholds for sensing ankle inversion and eversion movements in seven geriatric patients with peripheral neuropathy (PN) confirmed by nerve conduction studies and seven age- and gender-matched (C) controls with normal nerve conduction function, The PN group had a 3.6-fold larger (p = 0.0026) threshold (mean [SD] 1.37[1.74]degrees) for perceiving the presence and direction of an ankle rotation at a 75% rate of success (TH75) than did the C group (0.3[0.17]degrees). Inversion acuity was approximately twice that of eversion acuity in both groups, The PN group demonstrated better proprioceptive acuity in unipedal stance than in bipedal stance, whereas no such difference was found in the C group. Semiquantitative clinical tests of PN group proprioception at the ankle performed in the seated position failed to demonstrate significant differences from controls save in one case; however, the results of such tests at the toe were abnormal in all patients, In the geriatric population, PN is associated with deficits in ankle proprioception known theoretically to hamper maintenance of unipedal balance. It is significant that these deficits are associated with a clinically demonstrable loss of position sense at the toe but not the ankle.
