Objectives:To evaluate with meta-analysis the clinical effects of physiotherapeutic scoliosis spe-cific exercises(PSSE)comparing with other conservative treatments in treating adolescent idiopathic scoliosis(AIS).Methods:PubMed,Web of Science,The Cochrane Library,WanFang Data and China National Knowl-edge Infrastructure(CNKI)were searched by computer from their establishments to July 2023.The randomized controlled trials(RCTs)of PSSE therapy(PSSE therapy group)and other conservative treatments(control group)in treating AIS were collected.Two researchers independently screened the literature,extracted data and assessed the risk of bias of the included studies.Meta analysis was performed using RevMan 5.4 software on the Cobb angle,angle of trunk rotation(ATR),and quality of life score of Scoliosis Research Society-22(SRS-22)scale reported in the included literature,and subgroup analysis was carried on according to Cobb angle and treat-ment duration.Results:A total of 14 studies were included,consisting of 16 RCTs(2 studies included 2 RCTs each),involving 944 AIS patients.The quality of the literature was of medium and high.Meta analysis results showed that,comparing with the control group,the PSSE therapy group was superior in reducing Cobb angle of AIS patients(MD=1.64;95％CI:2.78,0.50;P＜0.05)and ATR(MD=1.45;95％CI:-2.58,-0.32;P＜0.05),and improving the SRS-22 quality of life score(MD=0.25;95％CI:0.17,0.33;P＜0.05).The results of subgroup analysis showed that for the AIS patients with duration of treatment ≤6 months(MD=-2.88;95％CI:-3.85,-1.91;P＜0.05)and a Cobb angle＜25° at enrollment(MD=-2.41;95％CI:-3.51,-1.30;P＜0.05),the PSSE therapy group had a better effect with a smaller Cobb angle(P＜0.05)than the control group.In terms of ATR improvement,for the patients with treatment duration ≤6 months(MD=2.63;95％CI:3.30,1.96;P＜0.05),the PSSE therapy group had a lower ATR degree comparing with the control group(P＜0.05).Conclusions:Comparing with other conservative treatments,PSSE therapy has advantages in improving the Cobb angle,re-ducing ATR and improving the quality of life in AIS patients,especially for mild scoliosis patients with Cobb angle＜25°.PSSE therapy has a better therapeutic effect on reducing the Cobb angle and ATR more obvious-ly in AIS patients with duration of treatment ≤6 months.

OBJECTIVE:At present,there are a variety of treatment methods for scoliosis using specific exercise therapy,but there is a lack of comparison of efficacy between different specific exercise therapy.This article compared the effectiveness of different specific exercise therapies to treat adolescent idiopathic scoliosis through a network meta-analysis. METHODS:Domestic and foreign electronic databases of relevant studies were searched for randomized controlled trials of specific exercise therapy for adolescent idiopathic scoliosis.Search time was from January 2000 to July 2023.The literature was screened by two reviewers using RevMan 5.4 and Stata 16.0 software to extract data and assess the bias risk of of inclusion studies. RESULTS:(1)This article includes 20 randomized controlled trials with 1 377 patients.Of them,12 studies involved Schroth therapy;2 studies involved BSPTS therapy,and 6 studies involved SEAS therapy.(2)The network meta-analysis indicated that in terms of improving Cobb angle and reducing trunk rotation angle in scoliosis patients,the BSPTS therapy group and Schroth therapy group were better than the conventional control group[WMD=-4.60,95%CI(-8.37,-0.82),P<0.05;WMD=-3.37,95%CI(-4.98,-1.75),P<0.05;WMD=-3.20,95%CI(-5.50,-0.90),P<0.05;WMD=-2.13,95%CI(-3.16,-1.09),P<0.05].The Schroth therapy group performed better than the conventional control group effective in improving the International Society for Scoliosis Research-22 Questionnaire quality of life score[WMD=1.41,95%CI(0.07,2.75),P<0.05]. CONCLUSION:Given the current evidence,BSPTS therapy group and Schroth therapy group were better than the conventional control group in improving Cobb angle and reducing trunk rotation angle.In the comparison of different specific exercise therapies,BSPTS therapy can be preferred to improve Cobb angle and reduce trunk rotation angle in adolescent idiopathic scoliosis patients.In addition,Schroth therapy may be the best treatment to improve the quality of life of adolescent idiopathic scoliosis patients.Limited by the quantity and quality of the included studies,the above conclusions should be interpreted with caution and need more high-quality studies to further validation.

Objective To study the effect of multi-point multi-axis suspension training on nonspecific low back pain (NLBP) through surface electromyography (sEMG). Methods From October, 2016 to November, 2017, 24 patients with unilateral NLBP (NLBP group) were randomly divided into dynamic group (n=12) and static group (n=12); other 12 healthy volunteers were selected as control group. NLBP group was trained on multi-point multi-axis suspension training system, the dynamic group accepted pelvic-up training in the supine position, while the static group accepted lumbar neutral keep training, for ten days. NLBP group was measured with average electromyographic values (AEMG) of affected musculi multifidi before and after treatment, and assessed with Visual Analogue Scale (VAS) of pain; while the control group was measured AEMG of unilateral musculi multifidi. Results The AEMG in static and pelvic-up positions was more in NLBP group than in the control group before treatment (t>3.209, P<0.01), and it was less when keeping neutral position (t=-2.364, P<0.05). The AEMG improved in NLBP groups after treatment (t>2.982, P<0.01). The AEMG in static position and in keeping neutral position was not significantly different among the three groups after treatment (F<2.921, P>0.05), and it was the most in the dynamic group as pelvic-up (P<0.001). The score of VAS decreased in both NLBP groups after treatment (t>10.416, P<0.001), and it was less in the static group than in the dynamic group (t=-4.389, P<0.001).Conclusion sEMG changes take place in patients with NLBP. Multi-point multi-axis suspension training is effective through improving the core muscle group, and it is more effective in static maintenance training.

Objective To explore the clinical effect of sling exercise on postpartum low back pain (PLBP). Methods From February, 2017 to February, 2018, 66 PLBP patients were randomly divided into control group (n = 33) and observation group (n = 33). The control group received routine rehabilitation physiotherapy and American chiropractic, and the observation group was supplemented with sling exercise therapy additionally. They were evaluated with Numerical Rating Scale (NRS), Oswestry Disability Index (ODI) and the thickness of transversus abdominis before and six weeks after treatment. Results Before treatment, there was no significant difference in the scores of NRS, ODI and the thickness of transversus abdominis between two groups (P > 0.05). Six weeks after treatment, the scores of NRS and ODI significantly decreased (t > 14.579, P < 0.001), and the transversus abdominis thickness significantly improved (t > 15.855, P < 0.001) in both groups. All the above indexes were significantly better in the observation group than in the control group (t > 4.818, P < 0.001). Conclusions ling exercise therapy, combined with American chiropractic treatment and routine rehabilitation physiotherapy, can further relieve pain in patients with PLBP, and improve the function and the quality of life.

Objective: To observe the clinical efficacy of the Mulligan technique in treating cervical vertigo (CV) in a hyperbaric oxygen (HPO) environment. Methods: Sixty-eight CV patients were randomly divided into a control group and an observation group, each of 34. Both groups were given routine treatment with ultrashortwave irradiation, but the observation group was additionally provided with 15 minutes of treatment based on the Mulligan technique in an environment with oxygen at 0.2 MPa, five days a week for two weeks. Both groups were assessed using the cervical vertigo symptoms and functional assessment scale (ESCV) and the daily frequency of vertigo was recorded before the treatment and 2, 4, 7, 14 and 60 days after treatment began. Moreover, the mean blood flow velocity in the patients′ vertebral (VA) and basilar arteries (BA) was detected using transcranial Doppler sonography before the treatment and after two weeks and two months. Results: There were no significant differences between the two groups in any of the measurements before the intervention. Afterward, however, significant improvement in all of the measurements was observed compared with before the treatment. After two weeks and two months the average ESCV score, daily occurrence of CV and mean VA and BA blood flows in the observation group were all significantly superior to those of the control group at the same time points. Conclusion Treatment based on the Mulligan technique in an environment with 0.2 MPa partial pressure of oxygen is a more effective way to relieve the symptoms of cervical vertigo and reduce the frequency of its occurrence. Such treatment is worthy of application in the clinic.
