[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 鹵2.56ml / kg 路min / kg 26.49 鹵3.45ml/min/kg), the maximum heart rate (143.35 鹵20.01bmpg) 170.95 鹵11.93bmp, the heart rate (102.35 鹵12.16bmpg, 120.25 鹵10.07bmp), the maximum respiratory exchange rate (1.15 鹵0.041.22 鹵0.05), the exercise time (12.55 鹵0.61min, 13.47 鹵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.
