目的 研究核心区肌群功能性训练预防新兵下背痛和提高核心肌功能的效果.方法 随机选取某海军训练基地健康男性新兵作为受试对象,将其随机分为核心肌训练组和常规腰肌锻炼组.两组分别接受为期12周的核心区肌群功能性训练和常规腰腹肌锻炼,锻炼方案为:每周3～5次且随周期递增,每次完成3组动作,每次锻炼30 min.由康复科治疗医师在第4、8、12周时进驻训练基地调查新兵下背痛发病情况,在第1、12周时由2位固定医师对新兵进行腰腹核心区肌群稳定性俯桥测试和腰背核心区肌群耐力测试.结果 成功收录588名新兵,其中核心肌训练组295名,常规腰肌锻炼组293名.在第12周时,核心肌训练组新兵下背痛发生率低于常规腰肌锻炼组[1.13％(3/266)vs 6.07％(15/247),P=0.002].两组新兵第12周时的俯桥、腰肌耐力测试值均较第1周增加,但核心肌训练组的增长幅度大于常规腰肌锻炼组(P均<0.01).结论 核心区肌群功能性训练较常规腰肌锻炼更能有效预防下背痛,其对腰腹部核心肌维持脊柱稳定性的增强及对腰背肌耐力的改善均优于常规腰肌锻炼.

Objective:To evaluate the clinical significance of Baduanjin in treating chronic lumbago and to assess the value of Baduanjin in improving the waist and abdominal muscle function.Methods:A total of 90 cases of chronic lumbago patients from rehabilitation medicine department were randomly divided into the treatment group and the control group.Patients from the control group were treated with magneto-caloric and interferential electrotherapy,while patients from the treatment group were added with Baduanjin.VAS,Roland-Morris questionnaires and intra-abdominal pressure were conducted in two groups before and after treatment.Results:After 12 weeks of treatment,VAS and Roland-morris questionnaire score of lumbar dysfunction in two groups decreased significantly (P＜0.05).And the differences of VAS and Roland-Morris questionnaire score of lumbar dysfunctionbetween two groups were significant (P＜0.01).After 12 weeks,the intra-abdominal pressure of the treatment group increased a little,however there was no statistically difference between two groups (P＜0.01).Conclusion:The combination of Baduanjin and physical therapy is better than physical therapy in lowering back pain index and improving the quality of life of patients,and improving the waist and abdominal function in some degree,which is worth to be promoted in the patients with chronic lumbago.

Objective To investigate the position sense in chronic non-specific low back pain (CNLBP) patients, and the correlation to pain and endurance of psoas muscles. Methods From January, 2014 to May, 2015, 30 patients with CNLBP and other 30 healthy subjects were measured spine flexion and extension position sense absolute error (AE) and psoas endurance with Biodex System 3 synchronously, and the patients were self-assessed the pain in lumbar with Numerical Rating Scale (NRS). The Pearson correlation coefficient of AE to pso-as endurance and NRS was calculated. Results AE of flexion and extension was both more in the patients than in the healthy (t>1.862, P<0.05), and the psoas muscle endurance was less (t=2.307, P<0.05). AE of flexion (r=-0.71) and extension (r=-0.47) negatively correlated with the psoas muscle endurance in the patients, and positively correlated with NRS score (r=0.78 for flexion, and r=0.49 for extension). AE mildly negative correlated with the psoas muscle endurance (r=-0.38 for flexion, and r=-0.29 for extension). Conclusion Spine sensation has been impaired in CNLBP patients, and may associate with pain and psoas muscles endurance loss.

新兵高强度训练并随之引发的下腰痛高复发率,是长期困扰基层训练的一大难题.在研究、跟踪下腰痛运动康复新理念、新技术、新方法的基础上,提出从下腰痛常识教育、腰部运动管理、日常保健教育、心理教育四个方面介绍综合预防训练性下腰痛的实践做法,以期达到减少腰痛患病率、促进下腰痛快速康复、提高士兵体能、增强战斗力的战略目的.

Objective:To make strategies for troops by surveying the incidence of low back pain and prevention measures in different positions.Methods:We chose 610 people from a Navy unit through stratified sampling methods.They were surveyed by a questionnaire uniformly and did data entry and statistical analysis.Results:The overall prevalence of low back pain is 70.9％,including 58.8％ in shore-based soldiers,and 81.2％ in naval soldiers.The naval soldiers' prevalence of low back pain was significantly higher than the shore-based soldiers (P＜0.05).The prevalence rates were 89.0％,93.8％,91.3％ and 78.1％ respectively in Warship posts,electromechanical soldiers,rigging soldiers,gun sail soldiers,observation soldiers and nautical soldiers.But the back pain prevalence rate was 55.2％ in Sailing soldiers and 44.4％ in Chef soldiers.And they had lower back pain prevalence rates with other jobs.Soldiers serving more than six years have higher back pain prevalence rates over 81.5％,and it was significantly higher than those who served less than six years.The 73.2％ of low back pain officers had not received treatment before.Only 1.8％ of people get rehabilitation exercises.The 92.7％ of people did not understand the waist core muscle training methods.Conclusion:The surface ships of different positions show high prevalence of low back pain,and the risk increased with the extended service life.Core muscle training will be useful for back pain prevention.
