目的 了解慢性期脑卒中患者吸气肌功能状况。方法 2017年1月至12月,脑卒中慢性期患者40例(患者组)、健康人40例(对照组),采用PowerBreathe K5吸气肌评估及训练系统评估吸气肌力指数和吸气功能。结果 患者组平均肌力指数、最大肌力指数、平均吸气峰流速、最大吸气峰流速、平均吸气量、最大吸气量均较对照组明显降低(t>3.196, P<0.01),肌力指数预计值与实际值的差显著升高(t=8.269, P<0.001);两组吸气肌肌力指数正常预计值无显著性差异(t=0.727, P>0.05)。结论 脑卒中慢性期患者吸气肌功能减弱,应加强吸气功能训练。
Objective To determine the inspiratory muscle function of chronic stroke patients. Methods From January to December, 2017, 40 chronic stroke patients and 40 healthy controls were tested inspiratory muscle function with Power Breathe K5. Results Compared with the controls, the average inspiratory muscle strength index, the maximum inspiratory muscle strength index, the average and maximum peak inspiratory flow, the average and maximum inspiratory capacity decreased (t>3.196, P<0.01), and the difference between the predicted and actual average inspiratory muscle strength index increased (t=8.269, P<0.001) in the patients. There was no difference in the normal predicted value of inspiratory muscle index between two groups (t=0.727, P>0.05). Conclusion Inspiratory muscle function is impaired in chronic stroke patients, and need to be trained in rehabilitation.
