摘 要: 目的 探讨帕金森病与多系统萎缩P型(MSA-P)在震颤峰频率、功率及谐波方面的特点.方法 连续纳入2016年1-12月就诊于北京天坛医院的帕金森病患者48例,MSA-P患者22例.对上肢震颤患者在静止、姿势及持物1 000 g三种状态下进行肌电图震颤分析检查,下肢震颤患者在静止和姿势两种状态下检查.比较帕金森病和MSA-P患者在不同状态时震颤峰频率、功率及频谱谐波出现率的特点.结果 帕金森病组与MSA-P组峰频率在上肢静止[分别为(4.76±0.82)、(6.03±0.25) Hz,t=-2.161,P=0.037)、姿势[(5.25±0.88)、(7.66±1.90) Hz,t=-4.266,P=0.001)、持物1000g[(5.80±1.28)、(8.32±1.51)Hz,t=-6.436,P=0.000)及下肢姿势[(4.85±0.78)、(6.42±1.13)Hz,t=-3.001,P=0.012)状态差异均有统计学意义.帕金森病组与MSA-P组半宽功率在上肢静止时伸肌[15.70(5.82,32.96)、3.14(1.69,4.60) mg2/μ V2,Z=-2.008,P=0.037],姿势时伸肌[33.14(20.46,64.27)、10.02(7.11,14.60)mg2/μV2,Z=-3.627,P=0.000]、屈肌[27.49(9.48,41.74)、5.97(4.41,15.59) mg2/μV2,Z=-2.336,P=0.019],持物1 000 g时屈肌[17.80(9.40,36.60)、8.15(5.32,17.65) mg2/μV2,Z=-2.494,P=0.013]以及下肢姿势时屈肌[26.63(7.09,85.84)、3.78(2.51,7.12) mg2/μV2,Z=-2.049,P=0.045]差异均有统计学意义.帕金森病组与MSA-P组谐波出现率在上肢静止(82.5%、5.9%,χ2=29.096,P=0.000)、姿势(80.0%、5.9%,χ2=26.884,P=0.000)及持物1 000 g(65.0%、0,χ2=20.318,P=0.000)状态差异均有统计学意义.结论 帕金森病患者震颤峰频率低于MSA-P患者,但震颤功率及频谱谐波出现率高于MSA-P患者. Objective To summarize the characteristics of tremor peak frequency,power and harmonics occurrence rate between Parkinson's disease (PD) and multiple system atrophy-parkinsonism (MSA-P).Methods From January to December in 2016,48 PD patients and 22 MSA-P patients were enrolled in Beijing Tiantan Hospital.Upper limb tremor patients got tremor analysis test in rest,posture and holding 1 000 g states,while lower limb tremor patients in rest and posture states.Peak frequency,power and harmonics occurrence rate of tremor were compared between PD and MSA-P patients in different states.Results Peak frequency of PD and MSA-P patients in upper rest ((4.76± 0.82) Hz vs (6.03 ± 0.25)Hz,t=-2.161,P=0.037),posture ((5.25 ±0.88) Hz vs (7.66 ±1.90) Hz,t=-4.266,P=0.001),holding 1 000 g ((5.80 ± 1.28) Hz vs (8.32 ± 1.51) Hz,t =-6.436,P =0.000) and lower posture ((4.85 ±0.78) Hz vs (6.42 ± 1.13) Hz,t =-3.001,P =0.012) showed statistically significant difference.Half-width power of PD and MSA-P patients in upper rest (extensor:15.70 (5.82,32.96)mg2/μV2 vs 3.14 (1.69,4.60) mg2/μV2,Z =-2.008,P =0.037),in posture (extensor:33.14(20.46,64.27) mg2/μV2 vs 10.02 (7.11,14.60) mg2/μV2,Z =-3.627,P =0.000;flexor:27.49(9.48,41.74) mg2/μV2 vs 5.97 (4.41,15.59) mg2/μV2,Z =-2.336,P =0.019),in holding 1 000g (flexor:17.80 (9.40,36.60) mg2/μV2vs8.15 (5.32,17.65) mg2/μV2,Z=-2.494,P=0.013),and in lower posture (flexor:26.63(7.09,85.84) mg2/μV2 vs 3.78 (2.51,7.12) mg2/μμV2,Z=-2.049,P =0.045) showed statistically significant difference.Harmonics occurrence rate of PD and MSAP patients in rest (82.5% vs 5.9%,χ2 =29.096,P =0.000),posture (80.0% vs 5.9%,χ2 =26.884,P=0.000) and holding 1 000 g (65.0% vs 0,χ2 =20.318,P=0.000) had statistically significant difference.Conclusions Tremor peak frequency in PD patients was lower than that in MSA-P patients,while power and harmonics occurrence rate in PD
