目的
2
分析Wilson病(Wilson disease,WD)患者的震颤特征,探讨震颤程度的影响因素。
方法
2
选取2022年4月至2023年10月在安徽中医药大学神经病学研究所附属医院以震颤症状为主要运动障碍表现的WD患者63例,根据统一肝豆状核变性评分量表(unified Wilson’s disease rating scale,UWDRS)评估WD患者症状的严重程度,记录入组患者震颤部位及震颤类型、血清铜生化结果、肝纤维化指标、K-F环(Kayser-Fleischer Ring,K-F环),定量评估病变脑区,通过姿态测量传感器定量测量上肢姿势性震颤参数。总结分析震颤症状的临床特征,通过逐步回归法分析筛选出震颤程度的影响因素。
结果
2
表现震颤的患者男37例(58.70%),女26例(41.30%),震颤部位分布双侧上肢(73.00%)、单侧右上肢(17.50%)、单侧左上肢(9.50%)、头部(4.80%)、单左下肢(3.20%)和躯干(1.60%)、双侧下肢(1.60%),震颤类型分布姿势性震颤(100.00%)、单纯姿势性震颤(66.70%)、意向性震颤(33.30%)、混合性震颤(33.30%),扑翼样震颤(11.10%)、静止性震颤(7.90%),男女性别间在年龄、发病年龄、病程、血清铜离子浓度、K-F环、pSWE值比较,差异无统计学意义(

高信号程度、不稳定的情绪反应评分(UWDRS第54项)是影响上肢姿势性震颤评分的影响因素(

结论
2
WD的震颤特征以上肢姿势性震颤为主,震颤参数RMS-gyr更能反映WD患者上肢姿势性震颤的严重程度,K-F环、尾状核受损及情绪的不稳定是震颤程度变异性的影响因素。
Objective
2
To investigate the features of tremor in patients with Wilson’s disease(WD) and the influencing factors for the severity of tremor.
Methods
2
A total of 63 patients with WD who were hospitalized in the Affiliated Hospital of Institute of Neurology,Anhui University of Chinese Medicine,from April 2022 to October 2023 were enrolled,with tremor as the main manifestation of dyskinesia. The unified Wilson’s disease rating scale(UWDRS) was used to evaluate the severity of WD symptoms,and related data were recorded,including the location and type of tremor,serum copper,liver fibrosis markers,and K-F ring. Quantitative evaluation was performed for diseased brain regions,and a posture-measuring sensor was used to measure the parameters of upper limb postural tremor. The clinical features of tremor symptoms were summarized and analyzed,and the stepwise regression analysis was used to investigate the influencing factors for the severity of tremor.
Results
2
Among the patients with tremor,there were 37 males(58.70%) and 26 females(41.30%). The distribution of tremor locations was as follows:bilateral upper limbs(73.00%),unilateral right upper limb(17.50%),unilateral left upper limb(9.50%),head(4.80%),unilateral left lower limb(3.20%),trunk(1.60%),and bilateral lower limbs(1.60%). The types of tremor included postural tremor(100.00%),pure postural tremor(66.70%),intention tremor(33.30%),mixed tremor(33.30%),flapping tremor(11.10%),and resting tremor(7.90%). No significant differences were observed between males and females in terms of age,age of onset,disease duration,serum copper concentration,K-F ring,pSW
E values,or the distribution and type of tremor(
t
=0.380,0.790,-0.330,0.170,0.560,0.860;
P
=0.700,0.430,0.740,0.860,0.580,0.390). However,serum ceruloplasmin concentration was significantly higher in females than in males(
t
=-2.980;
P
=0.004).Tremor parameters,including frequency of acceleration signal(F-acc),root mean square of acceleration signal(RMS-acc),and root mean square of angular velocity signal(RMS-gyr),were positively correlated with the UWDRS postural tremor score of the upper limbs(
r
=0.530,0.740,0.770;
P
<
0.001,
<
0.001,0.017,
<
0.001). F-acc,RMS-acc,and RMS-gyr were also positively correlated with the UWDRS psychiatric symptom score(
r
=0.420,0.490,0.570;all
P
<
0.001). Additionally,RMS-gyr was positively correlated with the liver function score (
r
=0.360;
P
=0.004).K-F ring,the tremor parameter RMS-gyr,the degree of hyperintensity in the caudate nucleus,and the score of unstable emotional response(UWDRS item 54) were identified as influencing factors for the postural tremor score of the upper limbs(
t
=2.720,9.300,5.510,6.300;
P
=0.009,
<
0.001,
<
0.001,
<
0.001).
Conclusion
2
Postural tremor of the upper limb is the main feature of tremor in WD,and the tremor parameter RMS-gyr can better reflect the severity of postural tremor of the upper limb in WD patients. K-F ring,caudate nucleus damage,and emotional instability are influencing factors for the severity of tremor.
