目的 探讨运动训练对尿毒症血液透析患者下肢运动功能的影响.方法 将120例病情稳定的尿毒症血液透析患者,按照随机数字表法随机分为观察组和对照组,两组各60例.观察组在常规护理的基础上进行每周3次的运动训练,包括透析前的能力训练、透析过程开始后2h内的踏车运动、透析间期的30 min运动能力训练.对照组按常规护理方法进行护理,患者按原有的习惯进行运动,并给予适当的指导,干预时间为12周.采用6 min步行测试方法评估,比较干预前后两组患者下肢运动功能情况.结果干预前,观察组患者6 min步行测试距离为(473.40±26.35)m,对照组为(470.57±27.00)m,两组比较差异无统计学意义(t=-0.410,P=0.682).干预后,观察组患者6 min步行测试距离为(510.70±23.46)m,对照组为(474.80±25.33)m,两组比较,差异有统计学意义(t=-5.695,P=0.000).结论 运动训练可以提高尿毒症血液透析患者的下肢运动功能,达到提高患者生活质量的目的.

Objective To discuss the influence of exercise training on motor function of lower limb of the maintenance hemodialysis (MHD) patients with uremia.Methods Totals of 120 stable hemodialysis patients were randomly divided into experimental group and control group.On the base of routine nursing care,the experimental group received exercise training three times a week including the ability training pre-dialysis,treadmill training after two hours of dialysis progress,and 30 min athletic ability training during the interphase of dialysis.While the control group received the routine nursing care,and patients received appropriate exercises guidance according to their original habits.And 6 minutes walking test method was used,and the motor function of lower limb of patients were observed before and after the intervention.Results No significant difference was found in the 6 min walking distance between experimental group and control group before the intervention [(473.40 ± 26.35) vs (470.57 ± 27.00) meters;t =-0.410,P =0.682].After the intervention,the 6 min walking distance in experimental group was (510.70 ± 23.46) meters,and that in control group was (474.80 ± 25.33) meters,and the difference was statistically significant(t =-5.695,P =0.000).Conclusions Exercise training can enhance motor function of lower limb of hemodialysis patients with uremia,so as to achieve the purpose of improving their quality of life.
