| Objective: To observe the effect of inspiratory muscle training with threshold pressure load trainer on respiratory function in patients with Parkinson’s disease. Methods: Totally, 48 patients with Parkinson’s disease were randomly divided into treatment group and control group, 24 cases in each group. The control group was given routine rehabilitation training. On this basis, the treatment group was subjected to the threshold pressure load trainer for inspiratory muscle training additionally. Before and after 8 weeks of treatment, the maximum inspiratory pressure (MIP) and peak inspiratory flow (PIF) were used to evaluate the inspiratory muscle function. The forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), 1 second rate (FEV1/FVC) and peak expiratory flow (PEF) were used to evaluate pulmonary function. Results: After 8 weeks of treatment, the MIP, PIF, FVC, FEV1 and PEF in the two groups were significantly higher than those before treatment (all P＜0.05), and the above indexes in the treatment group were better than those in the control group (all P<0.05). FEV1/FVC after treatment in both groups were significantly higher than those before treatment (all P<0.05), but there was no significant difference between the two groups after treatment. Conclusion: Inspiratory muscle training using a threshold pressure load trainer in combination with conventional rehabilitation therapy can effectively improve inspiratory muscle strength and improve lung function in patients with Parkinson’s disease. |
