Deterioration in the function of the sensorimotor system is often seen in patients with diabetes and could be related to balance impairments. The purpose of this study was to determine the association between sensorimotor function and forward reach ability in patients with diabetes. Thirty-one patients with Type 2 diabetes went through a monofilament test of plantar touch-pressure threshold, an ankle joint reposition test for joint position sense, and a series of strength tests of the lower leg. These patients also performed the forward reach test in standing to measure the reach distance and displacement of the center of mass (COM), using a motion analysis system. Correlational and regressional analyses were conducted to determine the association between sensorimotor and balance parameters. It was found that greater reach distance and COM displacement were significantly correlated with lower plantar touch-pressure threshold and greater plantarflexion strength. Regression analysis showed that after controlling the variance in the subject characteristics, plantar touch-pressure threshold was a significant predictor for reach distance and COM displacement, while plantarflexion strength was also a significant predictor for COM displacement. These findings highlight the importance of the assessment of plantar sensitivity and the need for detailed balance or fall risk assessment for patients with impaired plantar insensitivity.
感觉运动系统功能的恶化在糖尿病患者中经常出现，并且可能与平衡障碍有关。本研究的目的是确定糖尿病患者的感觉运动功能与前向伸展能力之间的关系。31 名 2 型糖尿病患者接受了足底触压阈值单丝测试、踝关节位置觉重定位测试和一系列小腿力量测试。这些患者还使用运动分析系统在站立位进行前向伸展测试，以测量伸展距离和质心（COM）的位移。进行了相关和回归分析，以确定感觉运动和平衡参数之间的关联。结果发现，更大的伸展距离和 COM 位移与较低的足底触压阈值和更大的跖屈强度显著相关。回归分析表明，在控制受试者特征的方差后，足底触压阈值是伸展距离和 COM 位移的显著预测因子，而跖屈强度也是 COM 位移的显著预测因子。这些发现强调了评估足底敏感性的重要性，以及对足底感觉迟钝的患者进行详细的平衡或跌倒风险评估的必要性。
