详细
论证。据不同文献报道,在被诊断为多发性硬化的患者中,儿童占比约3%–10%。在所有患者中,约75%在疾病早期即出现步态异常。然而,在俄罗斯联邦卫生部于2022年批准的临床指南中,尚无针对儿童步态分析的仪器评估方法的数据。
研究目的。 利用步态分析仪器结合表面肌电图,研究复发缓解型多发性硬化患儿的运动状态特征。
材料与方法。本研究为单中心、前瞻性观察性全样本研究。研究对象为Russian Children’s Clinical Hospital精神神经科确诊为多发性硬化的9–17岁患者(n=38)。所有患者均接受下肢肌群的步态分析和表面肌电图评估,同时进行了6分钟步行测试以及 增强磁共振成像以评估 脑部和脊髓病变情况。
结果。研究对象的残疾程度较低(EDSS评分≤2.5),均可独立行走。6分钟步行测试 结果显示,大多数患者的步行距离符合该年龄段正常范围,平均步行距离为520.92米。在表面肌电图分析中,44.74%的患者表现出腓肠肌在单腿支撑相期间的肌电活动异常,表现为肌肉过早激活以及步态周期支撑相的持续激活,并出现第二个峰值。
结论。研究发现,患儿对运动负荷的耐受性降低,并在表面肌电图评估中显示腓肠肌存在异常激活模式,即步态周期的非负重期持续激活以及支撑期的过早激活。这些变化可作为医学康复的潜在指征,并有助于评估治疗效果。由于样本量的限制,该现象仍需进一步研究。
