目的观察健身椅子操训练对老年糖尿病周围神经病变患者的下肢肌力及平衡功能的效果。方法选取我院收治的60例老年糖尿病周围神经病变患者,根据患者入院就诊编号将其分为观察组与对照组,各30例。两组均开展糖尿病周围神经病变的针对性治...目的观察健身椅子操训练对老年糖尿病周围神经病变患者的下肢肌力及平衡功能的效果。方法选取我院收治的60例老年糖尿病周围神经病变患者,根据患者入院就诊编号将其分为观察组与对照组,各30例。两组均开展糖尿病周围神经病变的针对性治疗,观察组在基础上给予健身椅子操训练。比较两组干预前、后的平衡功能及下肢肌力。结果干预后,两组TUGT评定时间均缩短,30 s STS试验次数均增加,且观察组优于对照组(P<0.05)。结论对老年糖尿病周围神经病变患者在常规治疗的基础上给予健身椅子操训练,有助于改善患者下肢肌力水平,提高平衡功能。展开更多
目的:分析四肢联动在脑卒中患者心肺适能评估中运用的可行性,探索评估脑卒中患者心肺功能的适宜设备。方法:19位脑卒中患者均先后使用功率自行车和四肢联动两种设备进行两次症状限制性最大递增心肺运动试验,并用配对t检验分析两次试验...目的:分析四肢联动在脑卒中患者心肺适能评估中运用的可行性,探索评估脑卒中患者心肺功能的适宜设备。方法:19位脑卒中患者均先后使用功率自行车和四肢联动两种设备进行两次症状限制性最大递增心肺运动试验,并用配对t检验分析两次试验获得的峰值摄氧量(VO2peak)以及峰值心率(HRpeak)之间的差异,并采用Pearson相关系数检验它们的相关性。结果:两次试验获得的VO2peak以及HR peak存在高度相关(分别r=0.95和r=0.96),使用四肢联动获得的VO2peak明显高于功率自行车[(14.51±3.13)vs(12.60±3.52)m L·kg-1·min-1],HR peak也明显增加[(116.26±10.98)vs(104.53±11.79)min-1],且差异均有统计学意义(P<0.05)。使用四肢联动的患者疲劳程度较自行车轻(Borg呼吸困难:9.95±0.85 vs 14.79±1.23;Borg腿部疲劳:13.53±0.70 vs 15.95±0.85)。纳入研究的19位患者均能顺利完成两次试验,没有发生任何不良事件。结论:四肢联动在评估卒中患者心肺适能方面是安全、有效、可行的,其测试结果更贴近患者真实的心肺功能,并且不容易引起患者疲劳。展开更多

This paper presents methods for reconstruction and correction of solar radio images using the algorithm of rejections, the updated Weiner-filter, and the method CLEAN designed by Hegbomom (Pseudonym, 2009) for point sources. It is the process of numerical convolution in signal handling, an algorithm for separating weak-contrast formations on the solar which represents most points of the actual limb by using the ellipse equation. Consequently, the filling algorithm is applied by moving from the center to the ellipse points and filling each point by solar image data. Finally, a linear limb-darkening expression is used to remove the limb darkening. Different examples of the intermediate and final results are presented in addition to the developed algorithm.展开更多
