摘要
背景:国内外关于慢性非特异性腰痛生物反馈疗法和三维步态功能分析的相关研究已开展很多,但是对二者结合的研究少有报道。目的:利用三维步态分析采集步态参数数据,研究生物反馈助力电刺激对慢性非特异性腰痛患者步行能力的改变效果。方法:选择2021年6月至2022年9月在广东药科大学附属第一医院收治的60例慢性非特异性腰痛患者,男34例,女26例,年龄32-58岁。采用随机数字表法将60例患者分为对照组(n=30)与试验组(n=30),两组患者均接受腰部动态干扰电的常规治疗(20 min/次,1次/d,每周5次,持续治疗20次),对照组患者在常规治疗的基础上进行仰卧搭桥和俯卧搭桥的悬吊核心肌群训练(每周5次,持续治疗20次),试验组在对照组治疗的基础上进行生物反馈助力电刺激治疗(20 min/次,1次/d,每周5次,持续治疗20次)。比较分析两组患者治疗前后的腰痛评分、肌电信号平均值和步态参数。结果与结论:①两组患者治疗结束后的数字类比表评分、日本骨科协会(JOA)评分、Oswestry功能障碍指数均较治疗前明显改善(P<0.05),试验组治疗结束后的数字类比表评分、JOA评分、Oswestry功能障碍指数均优于对照组(P<0.05);②两组患者治疗结束后的腹直肌、臀大肌、竖脊肌表面肌电平均值均高于治疗前(P<0.05),试验组治疗结束后的腹直肌、臀大肌、竖脊肌表面肌电平均值均高于对照组(P<0.05);③两组患者治疗结束后的步宽、步速、步频、健患侧步长比值、健患侧支撑相比值、患健侧摆动相比值、健患侧髋关节及膝关节矢状面活动度和健患侧足偏角均优于治疗前(P<0.05),试验组治疗结束后的上述指标均优于对照组(P<0.05);④结果表明,生物反馈助力电刺激能明显缓解慢性非特异性腰痛,改善了患者下肢步行功能。
BACKGROUND:There have been many studies on biofeedback therapy and three-dimensional gait function analysis for chronic non-specific low back pain at home and abroad,but few studies on the combination of the two have been reported.OBJECTIVE:To study the effect of biofeedback assisted electrical stimulation on the change of walking ability in chronic non-specific low back pain by collecting gait parameter data through three-dimensional gait analysis.METHODS:Sixty patients with chronic non-specific low back pain,34 males and 26 females,aged 32-58 years,were selected and admitted to First Affiliated Hospital of Guangdong Pharmaceutical University from June 2021 to September 2022.They were divided into control group(n=30)and trial group(n=30)according to the principle of random allocation.Both groups of patients received conventional treatment of dynamic interference with the waist,20 minutes/time,once/day,5 times a week,for 20 times.The control group received supine bypass and prone bypass suspension core muscle training on the basis of conventional treatment,5 times a week,for 20 times.The trial group received biofeedback assisted electrical stimulation therapy on the basis of the control group,20 minutes/time,once/day,5 times a week,for 20 times.The low back pain score,the mean value of electromyography and the gait parameters were compared and analyzed before and after treatment between the two groups.RESULTS AND CONCLUSION:(1)After treatment,the numerical rating scale score,Japanese Orthopaedic Association score,and Oswestry disability index of the two groups were significantly improved compared with those before treatment(P<0.05).Numerical rating scale score,Japanese Orthopaedic Association score,and Oswestry disability index of the trial group were better than those of the control group(P<0.05).(2)After treatment,the mean values of surface electromyography of rectus abdominis,gluteus maximus,and erector spinae muscle in the two groups were higher than those before treatment(P<0.05),and the mean values of surface electromyography of rectus abdominis,gluteus maximus,and erector spinae muscle in the trial group were higher than those in the control group(P<0.05).(3)After treatment,the step width,step speed,step frequency,step length ratio between healthy and diseased sides,the relative value of support between healthy and diseased sides,the relative value of swing between diseased and healthy sides,the sagittal motion range of hip joint and knee joint between healthy and diseased sides and the foot angle between healthy and diseased sides were all better than those before treatment in both groups(P<0.05).The above indexes of the trial group were better than those of the control group after treatment(P<0.05).(4)These results suggest that biofeedback assisted electrical stimulation can significantly alleviate chronic non-specific low back pain,and improve the lower limb walking function.
