To assess hand function and grip force (GF) control in non-neuropathic diabetic individuals using traditional hand function tests and instrumented handles that provide information about the underlying neural mechanisms controlling simple manipulation tasks.
Twelve diabetic individuals (31-60 years-old) without neuropathy and 12 controls performed traditional functional tests (i.e., nine hole peg test, Jebsen-Taylor test, and maximum grip strength test) and were tested for GF control in two situations: holding a free moving instrumented handle and isometrically pulling fixed handles. Task performance in the tests and safety margin (SM - percentage of GF above the minimum needed to hold the handle) were the main dependent variables assessed.
There was no difference between diabetics and controls in any functional test and in SM in isometric pulling task. However, diabetics presented around twice lower SM than controls in the free holding task.
Diabetics showed no impairment in functional manipulation tasks. However, they presented a lower SM than healthy controls.
This lower SM suggests that diabetics may present sensory impairment that could put them at risk of losing objects during its manipulation. Also, it suggests that the applied experimental procedure is sensitive to detect mild sensory impairment in diabetics.
使用传统的手部功能测试和提供有关控制简单操作任务的潜在神经机制信息的仪器手柄，评估无神经病变的糖尿病个体的手部功能和握力（GF）控制。
12 名无神经病变的糖尿病个体（31-60 岁）和 12 名对照者进行了传统的功能测试（即九孔钉测试、Jebsen-Taylor 测试和最大握力测试），并在两种情况下测试了 GF 控制：握持自由移动的仪器手柄和等长拉动固定手柄。评估的主要因变量是测试中的任务表现和安全裕度（SM-超过握持手柄所需最小 GF 的百分比）。
在任何功能测试和等长拉力任务中的 SM 方面，糖尿病患者与对照组均无差异。然而，在自由握持任务中，糖尿病患者的 SM 比对照组低约两倍。
糖尿病患者在功能性操作任务中没有表现出损伤。然而，他们的 SM 比健康对照组低。
较低的 SM 表明糖尿病患者可能存在感觉障碍，这可能使他们在操作过程中容易失去物体。此外，这表明所应用的实验程序能够敏感地检测到糖尿病患者的轻度感觉障碍。
