PURPOSE: The purpose of this study was to investigate which treadmill walking training mode is more effective strategy for improving pulmonary function of persons with chronic stroke.
METHODS: Twenty-one chronic stroke patients were allocated and randomly to an experimental group (treadmill training with randomized speed control, n=11) and a control group (treadmill training without speed change, n=10). All participants received 30 minutes of neurodevelopmental treatment. In addition, the two groups performed treadmill training for 20 minutes each time with or without speed change. Speed change was applied 40%, 50%, 60%, 70% of Heart Rate Reserve. All the exercise programs lasted six weeks, with five times per week. Pulmonary function was assessed before and after exercise program by using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV).
RESULTS: In the both groups, FEV1 was significantly increased after training (p<.05). Compared to the control group, the experimental group showed 11.9% larger amount of change (p<.05). In the experimental group, FVC and MVV were significantly increased after training (9.9%, 7.6%, respectively) (p<.05). But in the control group, there was no significant difference in the FVC and MVV after training.
CONCLUSION: Treadmill training with randomized speed control will be a better positive rehabilitation program than treadmill training without speed change to improve pulmonary function in persons with chronic stroke.
