摘要:

文题释义:

肌肉减少症:随着增龄和老年化过程,老年人的肌量逐渐减少,肌肉力量与肌肉强度也出现相应的下降,称为肌肉减少症。

足底压力:人体足底压力分布反映有关足的结构、功能及整个身体姿势控制等情况。

背景:肌肉减少症是老年化社会进程中不可避免的疾病,肌肉力量的下降、关节灵活性的降低、足部的结构和功能发生改变会不同程度地引起老年人步态特征的改变。因此通过对比老年肌肉减少症患者与未患肌肉减少症的老年人足底压力测试数据,有助于为临床预测老年肌肉减少症患者的跌倒风险提供精准评价指标。

目的:探讨老年肌肉减少症患者的足底压力变化,为临床预测老年肌肉减少症患者的跌倒发生风险提供精准评价指标。

方法:应用Footscan2.0足底压力检测系统采集老年肌肉减少症患者和未患肌肉减少症的老年人对照组足底压力数据,对比分析受试者步长、步速、触地时长、足底分区压力、足底压力中心移动轨迹。试验经中国科学技术大学附属第一医院伦理委员会批准。

结果与结论:肌肉减少症组步长、步速较对照组均降低;肌肉减少症组触地时长较对照组延长;肌肉减少症组左足第二至第五脚趾区、第三跖骨区、足中部区、第四跖骨区、第五跖骨区足底压力变化与对照组相较差异有显著性意义;肌肉减少症组右足第二至第五脚趾区、第三跖骨区、第四跖骨区、第五跖骨区足底压力变化与对照组相比较差异有显著性意义;肌肉减少症组足底压力中心轨迹总长度、左右足椭圆短轴长度、左右足椭圆长轴长度变化与对照组差异有显著性意义。提示老年肌肉减少症患者步行能力、平衡控制能力较对照组减低,步态对称性较未患对照组变差。

Abstract:

BACKGROUND: Sarcopenia is an inevitable disease in the progression of aging society. Decrease of muscle strength and joint flexibility and variation in foot structure and function can cause the change of gait characteristics of the elderly to varying degrees. Therefore, by comparing the plantar pressure data of elderly patients with sarcopenia and healthy elderly people, it is helpful to provide accurate evaluation indexes for clinical prediction of fall risks in elderly patients with sarcopenia.

OBJECTIVE: To investigate the changes of plantar pressure in elderly patients with sarcopenia.

METHODS: The plantar pressure data of elderly patients with sarcopenia (experimental group) and elderly people without sarcopenia (control group) were collected by Footscan 2.0 plantar pressure test system. The step length, step speed, touchdown time, plantar zone pressure, plantar pressure center trajectory were compared and analyzed. The study protocol was approved by the Ethics Committee of the First Affiliated Hospital of USTC, China.

RESULTS AND CONCLUSION: The step length and speed of the experimental group were significantly lower than those of the control group. The touchdown time in the experimental group was higher than that in the control group. Significant differences between the two groups were found in the changes of plantar pressure in toes 2-5, metatarsal 3, mid foot, metatarsal 4, and metatarsal 5 of the left foot as well as in the changes of plantar pressure in toes 2-5, metatarsal 3, metatarsal 4, and metatarsal 5 of the right foot. The total length of the plantar pressure center trajectory and the short- and long-axis length of the ellipse in the left and right feet were significantly different between the experimental and control groups. These findings indicate that elderly patients with sarcopenia have lower walking and balance control abilities as well as worse gait symmetry as compared with healthy controls.

Key words: sarcopenia, plantar pressure, gait analysis, lower limb biomechanics, step length, step speed, touchdown time, plantar pressure partitions, plantar pressure center trajectory
