观察反馈式抗阻吸气肌训练对脊髓损伤患者呼吸功能的影响

The Effects of Feedback Resistance Inspiratory Muscle Training on Respiratory Function of Spinal Cord Injury

目的观察反馈式抗阻吸气肌训练对脊髓损伤(SCI)患者吸气肌力量、呼吸困难程度和呼吸系统并发症发生率的影响。方法66例SCI患者随机分为对照组和试验组,每组各33例,对照组给予常规康复训练加腹式呼吸训练,试验组予以常规康复训练加反馈式抗阻吸气肌训练,治疗前、治疗4周后评估最大吸气压(MIP)、吸气流速峰值(PIF)、呼吸困难程度及呼吸系统并发症发生率,比较两组患者呼吸功能的改善情况。结果治疗4周后两组MIP、PIF均高于治疗前(P<0.05);且试验组MIP、PIF高于对照组(P<0.05);治疗4周后两组呼吸困难程度评分低于治疗前(P<0.05),且试验组低于对照组(P<0.05);两组呼吸系统并发症发生率比较,差异无统计学意义(χ^2=0.64,P>0.05)。结论反馈式抗阻吸气肌训练可明显改善SCI患者的吸气肌力量、减轻呼吸困难程度。

Objective To observe effects of the feedback resistance inspiratory muscle training on muscle strength、degree of dyspnea、respiratory complications in patients with spinal cord injury.Method 66 patients with dyspnea after spinal cord injury were randomized into 2 groups as experimental group(n=33)and control group(n=33),receiving routine rehabilitation activities,but the experimental group received feedback resistance inspiratory muscle training and the control group received abdominal respiration.They were assessed with maximum inspiratory pressure(MIP)、peak inspiratory flow(PIF)、degree of dyspnea and incidence of respiratory complications before and after four weeks′treatment.Results After 4 weeks of treatment,the MIP and PIF were higher in both groups than that before treatment(P<0.05);the MIP and PIF were higher in the experimental group than those in the control group(P<0.05);the dyspnea score was lower in both groups than that before treatment(P<0.05),and the experimental group was lower than the control group(P<0.05);there was no significant difference in the incidence of respiratory complications between the two groups(χ^2=0.64,P>0.05).Conclusion The feedback resistance inspiratory muscle training can improve MIP、PIF and degree of dyspnea in spinal cord injury.
