【摘要】：目的:观察上肢功率车在脊髓损伤(spinal cord injury,SCI)截瘫患者心肺运动试验中应用的可行性并分析SCI截瘫患者的心肺功能状态,探讨SCI截瘫患者有氧运动适合的评价指标。方法:招募20例SCI截瘫患者(试验组)及20名健康人(对照组),所有受试者在K4b2气体分析仪的监测下,采用智能主被动上肢功率车进行心肺运动试验。受试者进入实验室,休息10min后开始上肢功率车运动,转速主动控制在50—60r/min。起始功率为0W,并以每2min增加10W的幅度递增,直至测试者出现限制性症状终止试验,监测整个运动过程的心肺指标、主观劳累程度、心率、血压等。结果:测试过程中两组受试者心率、收缩压及舒张压在时间效应上存在显著差异(P0.001);试验组与对照组比较发现,峰值摄氧量(19.38±2.56ml/min/kg,26.49±3.45ml/min/kg)、最大心率(143.35±20.01bmp,170.95±11.93bmp)、无氧阈时心率(102.35±12.16bmp,120.25±10.07bmp)、呼吸交换率的最大值(1.15±0.04,1.22±0.05)、运动时间(12.55±0.61min,13.47±1.13min)差异有显著性意义(P0.01);试验组无氧阈时所对应的主观劳累程度与对照组比较,差异无显著性意义(P0.05)。试验组获得的最大心率约为预期值的67%,对照组获得的最大心率约为预期值得85%。结论:对SCI截瘫患者采用上肢功率车运动进行心肺运动试验具有一定的可行性,SCI截瘫患者的心肺功能均有不同程度下降;主观劳累程度可作为此类患者有氧运动强度的适宜参数。
[Abstract]:Objective: to observe the feasibility of the application of upper limb power car in cardiopulmonary motor test in paraplegic patients with spinal cord injury (spinal cord injury,SCI), and to analyze the cardiopulmonary function of SCI paraplegia patients, and to explore the evaluation index of aerobic exercise for SCI paraplegia patients. Methods: twenty patients with SCI paraplegia (experimental group) and 20 healthy persons (control group) were recruited. All subjects were monitored by K4b2 gas analyzer and the cardiopulmonary exercise test was carried out with intelligent active and passive upper limb power vehicle. The subjects entered the laboratory and rested for 10min, then began to move the upper limb power car, and the rotational speed was controlled at 50 ~ 60 r / min. The initial power was 0 W and increased by 10 W per 2min until the test was terminated with restrictive symptoms and the cardiopulmonary indexes subjective tiredness heart rate and blood pressure were monitored during exercise. Results: there were significant differences in the time effect of heart rate, systolic blood pressure and diastolic blood pressure between the two groups (P0.001). The maximal oxygen uptake (19.38 卤2.56ml / kg 路min / kg 26.49 卤3.45ml/min/kg), the maximum heart rate (143.35 卤20.01bmpg) 170.95 卤11.93bmp, the heart rate (102.35 卤12.16bmpg, 120.25 卤10.07bmp), the maximum respiratory exchange rate (1.15 卤0.041.22 卤0.05), the exercise time (12.55 卤0.61min, 13.47 卤1.13min) were significantly different (P0.01), and there was no significant difference in the subjective tiredness between the experimental group and the control group (P0.05). The maximum heart rate obtained in the trial group was about 67% of the expected value, and the maximum heart rate in the control group was about 85% of the expected value. Conclusion: it is feasible to conduct cardiopulmonary exercise test in patients with SCI paraplegia by upper limb power vehicle exercise, and the cardiopulmonary function of SCI paraplegia patients is decreased to some extent. Subjective tiredness can be used as an appropriate parameter for aerobic exercise intensity of such patients.
