Introduction: Lumbopelvic pain (LPP) is common in pregnant women and has a significant negative effect on physical and psychological health. In this study, for the first time, we conduct a meta‐analysis to estimate the overall prevalence of LPP among pregnant women and clarify the reasons for the differences in the estimated results.Material and methods: A systematic search of four databases (PubMed, Embase, Web of Science and Cochrane Central Register of Controlled Trials) was conducted from inception until October 2022. Two reviewers conducted a methodological quality assessment. Random‐effects model analysis was used to estimate the pooled prevalence and the 95% confidence interval. Chi‐square tests and I²‐values were used to assess the heterogeneity. Subgroup analysis (according to the participants’ continent, age, body mass index [BMI], gestational age and study risk of bias), sensitivity analysis and random‐effects meta‐regression were used to explore the the sources of heterogeneity.Results: Of the 1661 unique citations, 38 studies (21 533 pregnant participants) were included in this systematic review and meta‐analysis. The overall pooled prevalence of LPP during pregnancy was 63% (95% CI: 0.57 to 0.69), with significant heterogeneity (I² = 99.1%, P < 0.001). The prevalence differed by participants’ continents, 71% (North America), 74% (South America), 63% (Asia), 64% (Europe), 59% (Africa) and 45% (Oceania). The prevalence differed by BMI, 64% (BMI 28). The prevalence differed by age, 72% (age 30 years). The prevalence were the same differed by study risk of bias, 63% (both low and moderate risk of bias studies). The prevalence were similar by gestational age, 62% (second trimester) and 63% (third trimester).Conclusions: Lumbopelvic pain during pregnancy is common; about three‐fifths of pregnant women experience LPP. More prevention and intervention research for lumbopelvic should be conducted in pregnant women with different clinical characteristics.

Background: The application of cerebellar transcranial magnetic stimulation (TMS) in stroke patients has received increasing attention due to its neuromodulation mechanisms. However, studies on the effect and safety of cerebellar TMS to improve balance capacity and activity of daily living (ADL) for stroke patients are limited. This systematic review and meta-analysis aimed to investigate the effect and safety of cerebellar TMS on balance capacity and ADL in stroke patients. Method: A systematic search of seven electronic databases (PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang and Chinese Scientific Journal) were conducted from their inception to October 20, 2023. The randomized controlled trials (RCTs) of cerebellar TMS on balance capacity and/or ADL in stroke patients were enrolled. The quality of included studies were assessed by Physiotherapy Evidence Database (PEDro) scale. Results: A total of 13 studies involving 542 participants were eligible. The pooled results from 8 studies with 357 participants showed that cerebellar TMS could significantly improve the post-intervention Berg balance scale (BBS) score (MD = 4.24, 95%CI = 2.19 to 6.29, P < 0.00001; heterogeneity, I² = 74%, P = 0.0003). The pooled results from 4 studies with 173 participants showed that cerebellar TMS could significantly improve the post-intervention Time Up and Go (TUG) (MD=-1.51, 95%CI=-2.8 to -0.22, P = 0.02; heterogeneity, I² = 0%, P = 0.41). The pooled results from 6 studies with 280 participants showed that cerebellar TMS could significantly improve the post-intervention ADL (MD = 7.75, 95%CI = 4.33 to 11.17, P < 0.00001; heterogeneity, I² = 56%, P = 0.04). The subgroup analysis showed that cerebellar TMS could improve BBS post-intervention and ADL post-intervention for both subacute and chronic stage stroke patients. Cerebellar high frequency TMS could improve BBS post-intervention and ADL post-intervention. Cerebellar TMS could still improve BBS post-intervention and ADL post-intervention despite of different cerebellar TMS sessions (less and more than 10 TMS sessions), different total cerebellar TMS pulse per week (less and more than 4500 pulse/week), and different cerebellar TMS modes (repetitive TMS and Theta Burst Stimulation). None of the studies reported severe adverse events except mild side effects in three studies. Conclusions: Cerebellar TMS is an effective and safe technique for improving balance capacity and ADL in stroke patients. Further larger-sample, higher-quality, and longer follow-up RCTs are needed to explore the more reliable evidence of cerebellar TMS in the balance capacity and ADL, and clarify potential mechanisms.

Polycystic ovary syndrome (PCOS), a prevalent endocrine disorder among women, is frequently comorbid with depression. This systematic review and meta-analysis aimed to estimate the prevalence of depression among women with PCOS in mainland China. A comprehensive literature search was conducted in PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and Chinese databases (CNKI, WanFang, and VIP) up to August 2024. Random-effects models were applied to estimate the pooled prevalence of depression with 95% confidence intervals. The methodological quality assessment was assessed using the risk of bias tool. The primary outcome was the pooled prevalence of depression in women with PCOS. Thirty-nine studies encompassing 9796 participants were analyzed. The pooled prevalence of depression was 37% (95% CI, 29%-44%), with substantial heterogeneity (I2 = 96%, p < 0.001). In subgroup analysis, the prevalence of depression among women with PCOS in West, Central, East, and Northeast China was 37%, 37%, 38%, and 25%, respectively. The prevalence of depression among women with PCOS surveyed before and after 2015 was 40% and 35%, respectively. The prevalence of depression among women with PCOS aged < 26 and > / = 26 years were 42% and 33%, respectively. The prevalence of depression among women with PCOS that participants’ BMI < 24 and > / = 24 kg/m2 were 38% and 34%, respectively. The prevalence of depression among women with PCOS that used Self-rating Depression Scale (SDS), Patient Health Questionnaire-9 (PHQ-9), Beck Depression Inventory (BDI), and Hospital Anxiety and Depression Scale (HADS) were 40%, 34%, 31%, and 24%, respectively. Sensitivity analysis and meta-regression confirmed the stability of the findings. Evidence of publication bias was detected. The high prevalence of depression among women with PCOS in China underscores the need for integrated screening and management. The results of this meta-analysis show high heterogeneity and indicate publication bias, which reduces the generalizability of the findings. Future research should address heterogeneity and enhance the applicability of results.

The effect of exercise intervention on balance capacity among type 2 diabetes mellitus (T2DM) patients has not been evaluated. The objective of this systematic review and meta-analysis is to investigate the effect of exercise intervention on balance capacity among T2DM patients compared to the control group (usual care, waitlist, no-treatment, education). We conducted a comprehensive literature search through PubMed, EMBASE, Physiotherapy Evidence Database (PEDro), Cochrane library, Web of Science (WOS) from inception to August 2020. The literature language was limited to English. Randomized controlled trials (RCTs) or quasi-experimental (Q-E) trials that examined the effect of exercise intervention on balance capacity among T2DM patients were included. We used the standard methods of meta-analysis to evaluate the outcomes of exercise intervention for balance capacity of T2DM patients. A total of 14 trials (11 RCTs and 3 Q-E trials) involving 883 participants were eligible. The meta-analysis of some studies demonstrated that exercise intervention could significantly improve Berg Balance Scale (BBS) (MD = 2.56; 95%CI [0.35, 4.77]; P = .02), SLST (Single Leg Stance Test) under the eyes-open (EO) condition (MD = 3.63; 95%CI [1.79, 5.47]; P = .0001) and eyes-close (EC) condition (MD = 0.41; 95%CI [0.10, 0.72]; P = .01) compared to control group. There was no significant difference in Time Up and Go Test (TUGT) (MD = −0.75; 95%CI [−1.69, 0.19]; P = .12) and fall efficacy (SMD = −0.44; 95%CI [−0.86, −0.01]; P = .05). Narrative review of some studies indicated that exercise intervention could improve postural stability measured by Sensory Organization Test (SOT) and Center of Pressure (COP) variables, etc. This systematic review and meta-analysis summarized that exercise intervention could improve balance capacity in T2DM patients. However, further studies with high quality are required to evaluate its effect.
