呼吸肌训练对脑卒中后躯干控制和平衡功能的影响

The effect of respiratory muscle training on trunk control and balance ability in stroke patients

目的:研究呼吸肌训练结合常规康复治疗对脑卒中患者躯干控制、平衡功能、日常生活能力的影响。方法:将60例脑卒中患者随机分为对照组和试验组各30例。两组均给予常规康复治疗,试验组同时给予呼吸肌训练,共4周。治疗前后,最大吸气压(MIP)评估吸气肌肌力,最大呼气压(MEP)评估呼气肌肌力,躯干损伤量表(TIS)评估躯干控制能力,Berg平衡量表(BBS)评估平衡功能,改良巴氏指数(MBI)评估日常生活能力。结果:治疗前两组MIP、MEP、TIS、BBS和MBI比较,差异均无统计学意义(P>0.05);治疗后对照组及试验组MIP、MEP、TIS、BBS和MBI功能均改善,且治疗后试验组上述指标功能改善较对照组明显,差异具有统计学意义(P<0.05)。结论:呼吸肌训练可改善脑卒中患者的呼吸肌肌力、躯干控制、平衡功能、日常生活能力。

Objective: To investigate the effect of respiratory muscle training combined with conventional rehabilitation therapy on trunk control, balance ability and activities of daily living in stroke patients. Methods: Sixty stroke patients were divided into control group and experimental group by random number table, 30 each, and received conventional rehabilitation therapy. Moreover, the experimental group underwent respiratory muscle training, for four weeks. In each patient, maximal inspiratory pressure(MIP) was measured for the inspiratory muscle strength. Maximal expiratory pressure(MEP) was measured for the expiratory muscle strength. The trunk control was measured using the Trunk Impairment Scale (TIS). The Berg balance scale(BBS) was used to assess the balance function. The modified Barthel index (MBI) was used to evaluate activities of daily living. Results: There were no significant differences in MIP, MEP, TIS, BBS and MBI between the two groups before treatment ( P >0.05). The MIP, MEP, TIS, BBS and MBI functions of the control group and the experimental group were improved after treatment ( P <0.05), and the functional improvement of the above indicators in the experimental group after treatment was significantly higher than that of the control group ( P <0.05). Conclusion: This study proved that RMT improved respiratory muscle strength, trunk control, balance function, and ADL in stroke patients.
