概括
患有2型糖尿病 (T2DM) 的老年人表现出体位控制受损,具有更大的摇摆和减少复杂性. 这表明T2DM患者的感知和行动脱,影响了平衡.
科学领域:
- 生物力学 生物力学
- 神经学 神经学
- 内分泌学 在内分泌学.
背景情况:
- 2型糖尿病 (T2DM) 损害了外周和中枢神经系统,影响了姿势控制,特别是在双重任务期间.
- 以前的研究表明,T2DM对平衡有负面影响,但对认知负载下的姿势摇摆的具体影响不太了解.
研究的目的:
- 通过单个和多个尺度的指标来研究T2DM对姿势摇摆的影响.
- 在双重任务协议中检查T2DM和没有T2DM的老年人之间的姿势控制差异.
主要方法:
- 24名非糖尿病老年人和20名T2DM老年人进行了静静的站立和双重任务 (视觉搜索).
- 使用可穿戴运动传感器测量姿势摆动,评估圆面积,冲动,路径长度和加速范围.
- 多尺度量化了中侧 (ML) 和前后 (AP) 方向的摆动复杂性.
主要成果:
- 与非糖尿病组相比,T2DM组表现出明显更大的摇摆面积,冲动,路径长度和加速范围.
- 在T2DM组中观察到减少ML摇摆复杂性.
- 虽然这两组在视觉搜索任务中表现出减少的摇摆,但只有非糖尿病组在姿势适应和视觉搜索性能之间表现出相关性.
结论:
- T2DM显著改变了单个尺度的摇摆测量,并减少了ML摇摆的复杂性,证明了单个和多个尺度指标在评估姿势控制中的实用性.
- 这些发现表明,T2DM患者的感知和行动可能脱,这会影响他们与认知需求整合姿势控制的能力.

2.0K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
