背景人类的手功能受到神经功能障碍的影响。我们假设中风后躯体感觉受损的程度可能与运动性瘫痪的严重程度有关。为了验证这一假说，我们调查了老年中风患者Brunnstrom分期与触觉障碍之间的关系。我们测量了两只手的触觉压力阈值和握力，并使用六个Brunnstrom阶段评估了手的运动障碍。用配对t检验检验卒中后偏瘫的差异。结果患侧与健侧的触压阈值和握力差异有统计学意义(P<0.01)。另外，Brunnstrom分级与患侧触压阈值呈负相关(r_s=0.43，p<0.01)，与握力呈正相关(r_s=0.82，p<0.01)。结论中风后感觉障碍的程度与−分级的运动性瘫痪程度有关。
BackgroundHuman hand functions are affected by neurological disturbances. We hypothesized that the degree of somatosensory impairments after stroke may be related to the severity of motor paralysis. In order to examine this hypothesis, we investigated the relationship between the classification of the Brunnstrom stage and tactile sensation impairments in elderly stroke patients.MethodsParticipants were 61 elderly inpatients with hemiparesis after stroke. We measured the tactile-pressure threshold and handgrip strength in both hands and assessed motor impairments of the hand using the six Brunnstrom stages. Differences due to hemiparesis after stroke were examined using pairedt-tests. Spearman's rank correlation was performed to elucidate the relationship between Brunnstrom stage scores and the tactile-pressure threshold or handgrip strength.ResultsSignificant differences were observed in the tactile-pressure threshold and handgrip strength between the impaired and unimpaired sides (p < 0.01). Furthermore, the Brunnstrom stage showed a negative relationship with the tactile-pressure threshold on the impaired side (rs= −0.43, p < 0.01) and a positive relationship with handgrip strength (rs= 0.82, p < 0.01).ConclusionThese results suggest that the degree of sensory impairments after stroke is related to the severity of motor paralysis classified by the Brunnstrom stage.
