背景资料：糖尿病周围神经病变（DPN）患者的感觉和运动技能存在缺陷，导致本体感觉反馈不足、姿势平衡受损和跌倒风险较高。目的：本研究调查了基于传感器的交互式平衡训练对老年糖尿病患者姿势稳定性和日常体力活动的影响。研究方法：39名老年DPN患者入组（年龄63.7 ± 8.2岁，BMI 30.6 ± 6，54%为女性），并随机分为干预组（IG）或对照组（CG）。IG接受了为糖尿病患者量身定制的基于传感器的交互式运动训练（每周两次，持续4周）。演习的重点是转移重量和跨越虚拟障碍。在训练过程中，身体穿戴传感器被实现以获取运动学数据并提供实时关节视觉反馈。结果测量包括在基线和干预后睁眼和闭眼的平衡测试期间测量的质心（CoM）摇摆、踝关节和髋关节摇摆的变化。在基线和随访时，还测量了48小时内的日常体力活动。协方差分析用于训练后结果比较。结果如下：与CG相比，IG中的患者在睁眼平衡测试期间显示出CoM摇摆（58.31%; p = 0.009）、踝关节摇摆（62.7%; p = 0.008）和髋关节摇摆（72.4%; p = 0.017）显著减少。在闭眼测量期间，IG组的踝关节摇摆也显著减少（58.8%; p = 0.037）。训练后，步行的步数在IG中显示出显著但不显著的增加（+27.68%; p = 0.064）。结论：这项随机对照试验的结果表明，DPN患者可以通过糖尿病特异性的、定制的、基于传感器的运动训练显著改善他们的姿势平衡。这些结果促进了可穿戴技术在运动训练中的使用;然而，需要将该技术与商用系统进行比较的未来研究来评估交互式视觉关节运动反馈的益处。(C)2015 S.

Background: Individuals with diabetic peripheral neuropathy (DPN) have deficits in sensory and motor skills leading to inadequate proprioceptive feedback, impaired postural balance and higher fall risk. Objective: This study investigated the effect of sensor-based interactive balance training on postural stability and daily physical activity in older adults with diabetes. Methods: Thirty-nine older adults with DPN were enrolled (age 63.7 +/- 8.2 years, BMI 30.6 +/- 6, 54% females) and randomized to either an intervention (IG) or a control (CG) group. The IG received sensor-based interactive exercise training tailored for people with diabetes (twice a week for 4 weeks). The exercises focused on shifting weight and crossing virtual obstacles. Body-worn sensors were implemented to acquire kinematic data and provide real-time joint visual feedback during the training. Outcome measurements included changes in center of mass (CoM) sway, ankle and hip joint sway measured during a balance test while the eyes were open and closed at baseline and after the intervention. Daily physical activities were also measured during a 48-hour period at baseline and at follow-up. Analysis of covariance was performed for the post-training outcome comparison. Results: Compared with the CG, the patients in the IG showed a significantly reduced CoM sway (58.31%; p = 0.009), ankle sway (62.7%; p = 0.008) and hip joint sway (72.4%; p = 0.017) during the balance test with open eyes. The ankle sway was also significantly reduced in the IG group (58.8%; p = 0.037) during measurements while the eyes were closed. The number of steps walked showed a substantial but nonsignificant increase (+27.68%; p = 0.064) in the IG following training. Conclusion: The results of this randomized controlled trial demonstrate that people with DPN can significantly improve their postural balance with diabetes-specific, tailored, sensor-based exercise training. The results promote the use of wearable technology in exercise training; however, future studies comparing this technology with commercially available systems are required to evaluate the benefit of interactive visual joint movement feedback.
