Efficacy of Physiotherapy Treatment in Primary Dysmenorrhea: A Systematic Review and Meta-Analysis

Aerobic exercise to alleviate primary dysmenorrhea in adolescents and young women: A systematic review and meta-analysis of randomized controlled trials

INTRODUCTION

Aerobic exercise has been confirmed to alleviate primary dysmenorrhea (PD) in adolescents and young women. However, the effect of the aerobic exercise type and dosage on PD alleviation was unclear. This research aims to assess the effect of aerobic exercise on PD and investigate the dose-response relationships.

MATERIAL AND METHODS

Systematic literature searches of Web of Science, Embass, Cochrane Library, PubMed, PsycNET, CINAHL, CNKI, Baidu Scholar, Google Scholar, and other Complimentary Medicine Database. PICOS standards were adopted in this research: participants were nonathlete women with PD; intervention was aerobic exercise of at least one menstruation cycle; comparator was any comparator; outcomes were pain intensity or pain duration; and study type was randomized controlled trials. The Cochrane Collaboration risk of bias tool was used to assess the quality of the research. Random-effect meta-analysis was conducted for pain intensity and pain duration, with prespecified subgroup analyses based on aerobic exercise components. The strength of the evidence was assessed using GRADE. This systematic review and meta-analysis was registered in PROSPERO (CRD42024533544).

RESULTS

The study identified 16 eligible studies, with 15 involving adolescents, totaling 918 participants aged 15 to 43, with an average age of 21.26 ± 13.15. The results confirmed that aerobic exercise can alleviate PD's pain intensity (standard mean difference (SMD) = -1.728 (p = 0.00), 95% CI [-2.26 to -1.31]) and pain duration (weighted mean difference (WMD) = -12.53 h, p = 0.01, 95% CI: -21.38 to -3.68). However, the heterogeneity of these two results was high. Subgroup analysis showed that Pilates (SMD = -3.17, 95% CI [-4.26 to -2.07]), low intensity (SMD = -1.64, 95% CI [-2.10 to -1.19]), 31-45 min duration (SMD = -3.05, 95% CI [-5.36 to -0.75]), ≤2 times per week frequency (SMD = -2.24, 95% CI [-3.36 to -1.12]), and a period cycle of 2 menstrual cycles (SMD = -2.21, 95% CI [-3.13 to -1.28]) had the maximum effect size.

CONCLUSIONS

Aerobic exercise was able to alleviate pain intensity and pain duration in adolescents and young women with PD. Moderate-quality evidence indicates that Pilates, low intensity, 46-60 min, ≤two times per week, or two menstrual cycles showed more efficiency in alleviating PD. Due to the limited data, future research should prioritize conducting randomized controlled trials of aerobic exercise interventions in younger age groups to develop personalized treatment strategies for adolescents.

Enhancing motor function in children with cerebral palsy: A Comparative study of pediatric tuina and conventional rehabilitation

OBJECTIVE

This study explores the impact of combining Pediatric Tuina (PT) with conventional rehabilitation on motor function in children diagnosed with cerebral palsy (CP).

METHODS

This controlled trial involved 115 CP-affected children aged 1 month to 13 years. They were allocated into an experimental group (n = 57) receiving PT and conventional rehabilitation, and a control group (n = 58) receiving only conventional rehabilitation for three months. The GMFM-88 scale was employed for evaluating motor function at the start and end of the treatment period.

RESULTS

Compared to the conventional rehabilitation group, the combination of PT and standard rehabilitation therapy showed significant improvement in motor function among children with CP after 3 months. There were no significant differences in baseline characteristics between the two groups. Children in the PT combined with the standard rehabilitation therapy group exhibited more prominent improvements in motor function (supine and rolling: experimental group 47.88 ± 5.02 vs control group 42.86 ± 10.30; sitting: experimental group 45.16 ± 18.52 vs control group 35.59 ± 18.97; total score: experimental group 147.88 ± 75.59 vs control group 118.90 ± 77.87; P = 0.045). Furthermore, there was a significant increase in scores for children after the combination therapy (pre-treatment 105.39 ± 85.76 vs post-treatment 147.88 ± 75.59; P = 0.045).

CONCLUSION

PT, when used in conjunction with conventional rehabilitation methods, significantly enhances motor function in children with CP. The study advocates for further extensive research to validate and understand the broader implications of PT in CP treatment.

Efficacy and Safety of Non-Pharmacological Therapies for Primary Dysmenorrhea: A Network Meta-Analysis

Background

This network meta-analysis (NMA) aimed to explore the impact of Non-pharmacological therapies (NPT) on alleviating primary dysmenorrhea (PD) symptoms and assess the effectiveness differences among various NPT.

Methods

We searched seven databases and summarized clinical trials of PD treated with NPT from inception to September 6, 2023. Randomized controlled clinical trials (RCTs) of PD treated with NPT. The outcomes were the Visual Analog Scale (VAS), the Cox menstrual symptom scale (CMSS), and response rate. Quality was assessed using the Cochrane risk of bias assessment tool. Pairwise meta-analysis and network meta-analysis (NMA) was performed by RevMan (5.4), Stata (15.0), and WinBUGS (1.4.3). The ranking probabilities for all treatment interventions were performed using the Surface Under the Cumulative Ranking curve (SUCRA).

Results

A total of 16 RCTs were finally included, involving 8 kinds of NPT. Results of pairwise meta-analyses: For the VAS score results, moxibustion (SMD: -0.591,95% CI: -0.916, -0.266) was more effective than acupuncture, acupuncture (SMD: -0.948,95% CI: -1.853, -0.044) was more effective than placebo, and yoga (SMD: 2.634,95% CI: -4.28, -0.988) was more effective than the blank control. NMA results: Compared to the blank control, acupuncture (SMD: -4.81; 95% CI: -6.63, -3.00), auricular point therapy (SMD: -4.36; 95% CI: -7.18, -1.60), yoga (SMD: -2.12; 95% CI: -3.13, -1.09), moxibustion (SMD:5.54; 95% CI: 3.33, 7.68), and placebo (SMD: 3.10; 95% CI: 1.03, 5.27) proved to be a superior reduction in VAS. The use of acupressure (SMD: 2.49; 95% CI: 0.03, 5.03), moxibustion (SMD: -2.45; 95% CI: -4.06, -0.71), and acupuncture (SMD: -1.72; 95% CI: -2.75, -0.56) demonstrated a greater decrease in VAS efficacy than placebo. The consolidated ranking outcomes indicate that moxibustion, acupuncture, and auricular acupoint therapy occupy high SUCRA positions across various outcome metrics.

Conclusion

Acupuncture, moxibustion and auricular point may be the best treatment for PD. In the future, more trials are needed to obtain higher-quality evidence and the best protocols.

Acute effects of virtual reality-based relaxation and exergaming on primary dysmenorrhea symptoms

Background/aim

Primary dysmenorrhea (PD) is a menstrual disorder with significant physical and psychological impacts. Physical activity and relaxation techniques are proven methods for managing PD. Advances in virtual reality (VR) suggest that immersive relaxation and exergaming could provide new avenues for symptom relief. This study aimed to investigate the acute effects of VR-based interventions on PD symptoms and compare them with a control group receiving Jacobson's Relaxation.

Materials and methods

A randomized, controlled, single-blind trial was conducted with 43 female participants aged 18-30 years with regular menstrual cycles and PD. Participants were allocated to three groups: (I) immersive VR relaxation, (II) nonimmersive VR exergaming, or (III) Jacobson's relaxation (control group). Each participant completed a single 20-min session of their assigned intervention. Primary outcomes included abdomino-pelvic pain intensity, menstrual symptom severity, sleep quality, and perceived intervention effectiveness.

Results

All interventions reduced pain (r = 0.78-0.85) and symptom severity (r = 0.73-0.88) (p < 0.05), with no sleep quality changes. Between-group comparisons showed the control group to be more effective than nonimmersive VR exergaming in reducing menstrual symptom severity (p = 0.021, η2 = 0.144) and yielded higher perceived effectiveness (p = 0.010, η2 = 0.182).

Conclusion

Both VR-based interventions and the control group effectively alleviated PD symptoms, with the control group providing the most consistent symptom relief. Despite promising results for VR-based methods, traditional relaxation may be more accessible and better tolerated.

Impact of Probiotic Supplementation and High-Intensity Interval Training on Primary Dysmenorrhea: A Double-Blind, Randomized Controlled Trial Investigating Inflammation and Hormonal Modulation

Background: Dysmenorrhea, categorized as primary (PD) or secondary (SD), significantly affects females during their reproductive years, impairing quality of life, performance, and social relationships. Alongside medical treatment, exercise and probiotics are complementary measures for managing PD and promoting health. This study examined the impact of probiotic supplementation and high-intensity interval training (HIIT) on PD severity, physiological modulation, and physical fitness. Methods: Participants, recruited according to the primary dysmenorrhea criteria, were divided into non-PD (control) and PD groups, with the PD group further classified into dysmenorrhea (Dysmen), dysmenorrhea with probiotics (DysmenPro), dysmenorrhea with exercise (DysmenEx), and dysmenorrhea with both (DysmenExPro). Interventions included 10 weeks of HIIT and probiotics. Pre- and post-intervention assessments included questionnaires on premenstrual and menstrual symptoms, physical fitness evaluations, and blood sample analyses for biochemical, hormonal, and prostaglandin levels. Results: HIIT significantly reduced premenstrual symptoms, menstrual distress, and pain severity, likely due to hormone (estradiol, prolactin, progesterone, cortisol) modulation and decreased inflammation (high-sensitivity C-reactive protein, PGE2, PGF2α). Cardiovascular endurance and explosive strength showed improvement through high-intensity interval training (HIIT), whereas probiotics had no significant effect on these aspects of physical fitness. While probiotics reduced premenstrual and menstrual distress symptoms, they had no notable impact on pain, inflammation, or hormone levels. Dysmenorrhea-related discomforts were correlated significantly with inflammation and hormones. Conclusions: The intervention strategy involving probiotics and HIIT exercise may be utilized as an alternative and complementary treatment to alleviate PD symptoms. Furthermore, this strategy could also be incorporated into educational health plans to promote women's health and potentially prevent gynecological disorders in the adolescent population.

Effects of Sacroiliac Joint Manipulation on Autonomic Nervous System and Lower Abdominal Pain in Women with Primary Dysmenorrhoea: A Randomized Controlled Trial

Background and Objectives: Autonomic nervous system (ANS) disorders are responsible for primary dysmenorrhea and are closely linked to the spine. This study aims to evaluate the effects of sacroiliac joint manipulation on the ANS and lower abdominal pain in women with primary dysmenorrhea and proposes an alternative treatment method. Materials and Methods: A total of 40 participants were randomly assigned; however, 35 participants remained in the final analysis after 5 dropped out; they were assigned to either the sacroiliac joint manipulation group (n = 18) or the superficial heat therapy group (n = 17). Assessments included heart rate variability (HRV), visual analogue scale (VAS) scores for lower abdominal pain, the pressure pain threshold (PPT) of the sacroiliac joint, and the Moos Menstrual Distress Questionnaire (MMDQ) at baseline and after 4 weeks. Only the VAS and MMDQ scores were reassessed after 8 weeks to evaluate the sustained effects of the treatment. Results: Changes in HRV showed improvements in ANS balance only in the sacroiliac joint manipulation group (p < 0.05). It was found to be more effective than superficial heat therapy (p < 0.05). A significant decrease in lower abdominal pain following the intervention was observed in both groups (p < 0.05), along with the sustained effects of the treatment (p < 0.05). The MMDQ scores decreased after sacroiliac joint manipulation (p < 0.05), with greater improvements compared to the superficial heat therapy (p < 0.05). Conclusions: Sacroiliac joint manipulation positively affects ANS balance and is effective in alleviating lower abdominal pain and menstruation-related symptoms, with sustained effects observed over time. Therefore, sacroiliac joint manipulation can be an effective alternative treatment for women with primary dysmenorrhea.

Transcutaneous Tibial Nerve Stimulation for Quality-of-Life Improvement and Sleep Deficiency in Women with Primary Dysmenorrhea: A Randomized Clinical Trial

Background: Primary dysmenorrhea is a leading cause of chronic cyclic pelvic pain, contributing to a reduced quality of life and sleep disturbances in women. The objective of this study was to assess the effectiveness of transcutaneous tibial nerve stimulation (TTNS) in improving the quality of life, sleep, and overall health perceptions of participants compared to a control group of women with dysmenorrhea over short-term, medium-term, and long-term periods. Methods: A single-blind, controlled clinical trial was conducted, with participants randomly assigned to an experimental group (receiving TTNS) or a control group (receiving sham TTNS). Both groups underwent 12, weekly 30 min sessions using the NeuroTrac™ PelviTone electrostimulation device. Outcomes related to quality of life, sleep deficiency, and overall improvement were evaluated at three time points: short-term (post-treatment), medium-term (1-3 months), and long-term (6 months). Results: Of the 61 participants initially randomized (31 in the experimental group and 30 in the control group), 55 completed the study and were included in the final analysis. A statistically significant improvement was observed in the experimental group in both physical and mental health components, as measured by the SF-36v2® questionnaire, following 12 weeks of intervention, compared to the control group, persisting 6 months after the intervention. Additionally, statistically significant differences in overall improvement were noted between the two groups, as measured by the PGIC questionnaire at the end of treatment (p = 0.0103) and 6 months post-treatment (p = 0.0432). Conclusions: TTNS appears to be a safe and effective strategy for enhancing quality of life and overall health in women with PD, potentially reducing the reliance on pharmacological treatments or more invasive methods.

Transcutaneous Tibial Nerve Stimulation for Pain Management in Women with Primary Dysmenorrhea: A Randomized Clinical Trial

Primary dysmenorrhea is considered one of the main causes of pelvic pain during a woman's childbearing years, resulting in poor quality of life. The objective was to evaluate the effectiveness of transcutaneous tibial nerve stimulation (TTNS) in painful symptomatology improvement and non-steroidal anti-inflammatory drug (NSAID) intake reduction in women with primary dysmenorrhea (PD) compared with a control group in the short, medium, and long terms. A single-blind, controlled clinical trial was developed. Participants were randomized to the experimental (TTNS) and control group (sham TTNS). Both groups received 12-weekly 30-min sessions with a NeuroTracTM PelviTone electrostimulation device. The intensity and severity of pain and non-steroidal anti-inflammatory drug (NSAID) intake were evaluated in the short-term (after treatment), medium-term (1-3 months), and long-term (6 months). A total of 61 participants were randomized, with a split of 31 (experimental group) and 30 (control group), but 55 participants completed the study and were analyzed. Statistically significant differences between both groups in the maximum pain intensity decrease (F = 4.88, p = 0.0043) measured with the visual analogue scale, as well as NSAID intake decrease (F = 4.68, p = 0.011) and days of their ingestion (F = 4.57, p = 0.012) occurred in the short term. Furthermore, significant decreases in the total number of NSAIDs ingested during the cycle (F = 3.82, p = 0.011) and the number of days on which patients ingested NSAIDs (F = 3.59, p = 0.015) in the medium-long term occurred. TTNS could be an effective and safe strategy to reduce pain caused by PD, which could reduce or complement the use of pharmacological techniques and other more invasive methods.

Comparative Effectiveness of Different Exercises for Reducing Pain Intensity in Primary Dysmenorrhea: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials

BACKGROUND

Studies have demonstrated that exercise can mitigate the intensity of menstrual pain in primary dysmenorrhea, but the most effective type of exercise remains unclear. The objective of this systematic review and network meta-analysis was to evaluate the effectiveness of different exercise regimens in reducing pain associated with primary dysmenorrhoea.

METHODS

Randomized controlled trials investigating the relationship between menstrual pain and exercise were selected from major electronic databases until February 2, 2024. The primary outcome was the effect of exercise on pain intensity measured by the mean difference on a 10-cm visual analogue scale at 4 and 8 weeks after intervention. The secondary outcome was the difference in risk of dropout at 8 weeks. The study protocol was registered as INPLASY202330050.

RESULTS

This systematic review and network meta-analysis included 29 randomized controlled trials, which involved 1808 participants with primary dysmenorrhea. Exercise interventions included relaxation exercise, strength training, aerobic activity, yoga, mixed exercise, and the Kegel maneuver. Relaxation exercise was the most effective in reducing menstrual pain in 4 weeks (- 3.56; 95% confidence interval: - 5.03 to - 2.08). All exercise interventions were effective in reducing menstrual pain at 8 weeks, with reductions ranging from - 3.87 (95% CI - 5.51 to - 2.22) for relaxation exercise to - 2.75 (95% CI - 4.00 to - 1.51) for yoga, compared to the control group. Relaxation exercises were found to have a significantly lower dropout risk (- 0.11; 95% CI  - 0.20 to 0.02), while none of the exercise types was associated with a higher dropout risk than the control group.

CONCLUSION

All exercise interventions were effective in reducing menstrual pain in primary dysmenorrhea after 8 weeks of intervention. However, relaxation exercise was found to be the most effective intervention at 4 and 8 weeks and had the lowest risk of dropout.

Manual Therapy in Primary Dysmenorrhea: A Systematic Review and Meta-Analysis

Objective

This research aimed to assess the effectiveness of manual therapy in alleviating pain among women undergoing primary dysmenorrhea (PD).

Methods

All randomized controlled trials (RCTs) regarding manual therapy for PD were searched from online databases, spanning from their inception to July 2023. The identified literature underwent a thorough screening process, and the data were meticulously extracted and analyzed using RevMan 5.3. Subsequently, the included studies underwent Cochrane's quality assessment and meta-analysis. The evidence obtained was then assessed using the grading of recommendations, assessment, development, and evaluation (GRADE) approach.

Results

32 RCTs, involving 2566 women were finally included for analysis. The overall quality of the concluding evidence was generally rated as low or very low. Performance bias and blind bias were found to be the main risk of bias of the included studies. In comparison to no treatment, manual therapy demonstrated a significant increase in pain relief in short-term (n=191, MD=1.30, 95% CI: 0.24~2.37). The differences in the effects of manual therapy and the placebo on pain intensity may not be statistically significant (n=255, MD=0.10, 95% CI: -0.37~0.58). In contrast to NSAIDs, manual therapy exhibited superior pain alleviation (n=507, MD=3.01, 95% CI: 1.08~4.94) and a higher effective rate (n=1029, OR=4.87, 95% CI: 3.29~7.20). Importantly, no severe adverse events were reported across all studies, indicating a relatively safe profile for manual therapy.

Conclusion

Manual therapy presented promise in effectively relieving menstrual pain with minimal adverse events in short term, outperforming both no treatment and NSAIDs. However, this conclusion is tempered by the low quality of the included RCTs, highlighting the necessity for more robust trials to validate it.

Treatment of Women With Primary Dysmenorrhea With Manual Therapy and Electrotherapy Techniques: A Systematic Review and Meta-Analysis

OBJECTIVE

The objective of this study was to evaluate the efficacy of electrotherapy and manual therapy for the treatment of women with primary dysmenorrhea.

METHODS

Systematic searches were conducted in Scopus, Web of Science, PubMed, CINAHL, and MEDLINE. The articles must have been published in the last 10 years, had a sample exclusively of women with primary dysmenorrhea, had a randomized controlled trial design, and used interventions that included some form of manual therapy and/or electrotherapy techniques. Two reviewers independently screened articles for eligibility and extracted data. Difference in mean differences and their 95% CIs were calculated as the between-group difference in means divided by the pooled standard deviation. The I2 statistic was used to determine the degree of heterogeneity.

RESULTS

Twelve selected studies evaluated interventions, with 5 evaluating electrotherapy techniques and 7 evaluating manual therapy techniques. All studies analyzed identified improvements in pain intensity and meta-analysis confirmed their strong effect.

CONCLUSIONS

Manual therapy and electrotherapy are effective for the treatment of women with primary dysmenorrhea. Transcutaneous electrical nerve stimulation combined with thermotherapy and effleurage massage stands out for its effects on the intensity and duration of pain with the application of a few sessions and their long-term effects.

IMPACT

Manual therapy techniques and electrotherapy methods reduce the pain intensity of women with primary dysmenorrhea. Quality of life and degree of anxiety improved significantly with manual therapy interventions. Transcutaneous electrical nerve stimulation combined with thermotherapy and effleurage massage are the interventions with which positive effects were achieved with fewer sessions.

The effects of taping in the management of primary dysmenorrhoea: A systematic review with meta-analysis

In this systematic review and meta-analysis, we explored the efficacy of taping as a non-pharmacological intervention for pain reduction in primary dysmenorrhoea (PD), a prevalent condition causing significant quality of life impairment. We conducted a comprehensive search across databases including PubMed, PEDro, and Web of Science to identify randomized controlled trials assessing taping's effectiveness in PD for pain relief. Our criteria focused on studies comparing taping to no intervention or alternatives, with pain outcomes primarily measured using the Visual Analogue Scale (VAS). The quality assessment utilized the PEDro scale, with scores ranging from 4 to 8, indicating a spectrum of moderate to high-quality evidence. The results indicate that both kinesiotaping (SMD = -1.22; 95 % CI: -2.15, -0.29; p = 0.01) and other tapes (SMD = -1.61, 95 % CI: -2.15, -0.65; p = 0.001) significantly reduces pain intensity in women with PD. However, the certainty of evidence was very low according to GRADE criteria. This underscores the necessity for further research to understand taping's analgesic mechanisms, its long-term effects, and its influence on related symptoms and overall quality of life. Our findings advocate for the inclusion of taping in PD management, offering a promising direction for enhancing care in affected women.

Translation, cross-cultural adaptation, and measurement properties of the dysmenorrhea symptom interference (DSI) scale-Brazilian version

BACKGROUND

The Dysmenorrhea Symptom Interference (DSI) scale is a reliable, valid, and responsive tool to assess the interference of menstrual pain in the physical, mental, and social activities of women.

OBJECTIVE

To translate and cross-culturally adapt the DSI scale into Brazilian-Portuguese (DSI-BrPt) and investigate the measurement properties of this version in on- and off-menses versions.

METHODS

The original (United States) scale was translated and culturally adapted following existing guidelines. Measurement properties of the DSI-BrPt were investigated in 1387 women with dysmenorrhea. Reliability was analyzed via intraclass correlation coefficients (ICC) and test-retest reliability. Furthermore, structural validity, internal consistency (Cronbach's alpha), cross-cultural validity, construct validity (correlation with WHODAS 2.0 and SPS-6 scores questionnaires), and floor and ceiling effects were determined.

RESULTS

No significant adaptations were needed during the translation process of the DSI-BrPt. The values of Cronbach's α were adequate (α ≥0.87) for the unidimensional scale. The test-retest reliability was considered adequate (ICC >0.78) and there was no systematic error for both on-menses and off-menses versions. Moreover, the DSI had a positive and strong correlation with WHODAS 2.0. There were no floor and ceiling effects neither for the total sample, nor among off-menses, or on-menses women.

CONCLUSION

The DSI-BrPt scale has been translated and cross-culturally adapted successfully. The DSI-BrPt scale presented adequate measurement properties. The scale is valid and reliable, and, therefore, an adequate tool for monitoring dysmenorrhea symptoms in Brazilian women during and between menses.

Efficacy of Connective Tissue Therapy and Abdominal Stretching Exercises in Individuals With Primary Dysmenorrhea: A Review

Dysmenorrhea is a menstrual disorder characterized by painful uterine cramps that occur during menstruation. There are two types of dysmenorrhea, primary and secondary. It affects 45-95% of all menstruating women worldwide. The prevalence in India is approximately 75%. Primary dysmenorrhea diagnosis is based on the patient's medical history and physical examination. If the history of start and duration of lower abdominal discomfort suggests secondary dysmenorrhoea or if the dysmenorrhoea does not respond to medical treatment, a pelvic examination is necessary to evaluate dysmenorrhoea. Because of the increasingly large number of women who are impacted by primary dysmenorrhea, it should be a public health concern that authorities must address. Abdominal stretching is a very simple, efficient, and risk-free workout. Some of the benefits of stretching exercises for dysmenorrhea include increased elasticity and strength of the spine and pelvic muscles and reduction in pain. The knee-to-chest exercise in combination with hydrocollator packs has a significant effect in improving the pain and the monthly irregularities in primary menstrual pain. Massage of connective tissue is a form of cutaneous stimulation that tries to stimulate the connective tissue's mechanical receptors. Connective tissue massage studies for treating a range of dysfunctions usually indicate that patients treated with this modality get pain alleviation and even complete remission.

Efficacy of manual therapy and pelvic floor exercises for pain reduction in primary dysmenorrhea: A prospective observational study

BACKGROUND

Primary dysmenorrhea represents one of the most common causes of pelvic and low back pain. Pharmacological treatment can present some side effects, and non-pharmacological treatments should be considered to improve the symptoms of primary dysmenorrhea. The aim of this study was to evaluate the efficacy of manual therapy (MT), pelvic floor exercises (PFE), and their combination (MT + PFE) to improve clinical outcomes and pain sensitivity in women with primary dysmenorrhea.

METHODS

A prospective observational study was conducted. Thirty females (age 25.0 ± 6.1 y) with history of primary dysmenorrhea participated to 8 sessions of 60 min of either MT, PFE or MT + PFE, twice per week. They participated to the different treatments according to the different services offered by the school of physiotherapy. A 0-10 numeric rating scale (NRS) was administered to assess subjective pain, while short-form 36 (SF-36) was used to evaluate quality of life. The pressure pain threshold (PPT) was assessed with a portable algometer on different pelvic and lumbar areas.

RESULTS

Independently from the treatment, significant improvements were reported for general pain NRS (p < 0.001; pη2 = 0.511), as well as most the domains of the SF-36, although the general health domain did not reach statistical significance (p = 0.613; pη2 = 0.010). PPT revealed a general improvement in all tested body areas, although on the quadratus lumborum, the PFE treatment did not induce a significant improvement compared to the MT and MT + PFE protocols (p = 0.039).

CONCLUSIONS

These findings highlight the importance of proposing physiotherapy treatments to females with primary dysmenorrhea to improve symptoms, with manual therapy combined with active pelvic floor exercise providing the best outcomes including an improvement of lumbar pain thresholds.

Effects of Pilates on Pain, Physical Function, Sleep Quality, and Psychological Factors in Young Women with Dysmenorrhea: A Preliminary Randomized Controlled Study

The effect of Pilates on dysmenorrhea has been little studied. The purpose of this study was to evaluate the effect of Pilates on menstrual pain and symptoms, premenstrual syndrome, and risk factors of dysmenorrhea. Thirty young women with primary dysmenorrhea were randomly assigned into a Pilates group (PG; n = 15) and a waitlist control group (CG; n = 15). The Pilates was performed twice a week for 12 weeks. Menstrual pain and symptoms were measured by visual analogue scale (VAS) and the Cox menstrual symptom scale (CMSS), respectively. Premenstrual syndrome was assessed using the premenstrual symptoms screening tool (PSST). Additionally, back flexibility, hip muscle strength, sleep duration and quality, perceived stress, state-trait anxiety, and depression were evaluated. The VAS, CMSS severity and frequency, and PSST symptoms and functional impairments decreased in the PG compared to the CG (p < 0.001 or p < 0.01) with large effect sizes. Back flexibility and the strength of hip flexors, hip extensors, and hip abductors significantly increased in the PG compared to the CG (all p < 0.01) with large effect sizes. Sleep quality (p < 0.01) and stress (p < 0.05) improved in the PG. Sleep duration, anxiety, and depression did not change in either group. In conclusion, the 12-week Pilates intervention ameliorates dysmenorrhea, partly mediated by improved physical function and sleep quality.

Long-Term Follow-Up Result of Connective Tissue Manipulation in Young Women with Primary Dysmenorrhea: Different Intervention Durations

The purpose of this study was to reveal the effect of connective tissue manipulation (CTM) on long-term pain severity, fatigue, sleep quality, premenstrual symptom severity, general health status, anxiety, and depression in women with primary dysmenorrhea (PD). Thirty-five women with PD were divided into two groups. CTM was applied to the participants in each group on the days when they were not on menstruation between two menstrual cycles for the group 1 (n=18) and between three menstrual cycles for the group 2 (n=17). Intensity of menstrual pain, the sleep quality, and fatigue status of the participants during dysmenorrhea were evaluated by the Visual Analog Scale (VAS). Depressive symptoms and anxiety were evaluated using the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI), respectively. Also, the Premenstrual Syndrome Scale (PMSS) and the General Health Questionnaire (GHQ) were used to investigate the severity of premenstrual symptoms and mental health status during menstrual period. A significant decrease in the pain severity and fatigue of the participants was observed in both group 1 and group 2 after treatment, after 3rd, and 6th month follow-up (p=0.001). Also, this decrease lasted for 12th month follow-up after treatment in group 2 (p=0.0001). There was no statistically significant improvement in sleep quality within each group (p>0.05). Moreover, none of the parameters were significantly different between two groups (p>0.05). We can suggest that 2-cycle CTM treatment should be preferred in clinical settings to obtain long-lasting effects for decreasing pain, fatigue, and premenstrual symptoms in women with PD. CLINICAL TRIAL NUMBER: NCT04509934. Registration date: 8 November 2020.

Transcutaneous Tibial Nerve Stimulation for Primary Dysmenorrhea: A Protocol for a Randomized Controlled Trial

Primary dysmenorrhea (PD) is a painful menstruation that can persist for the duration of a woman's fertile life. Non-steroidal anti-inflammatory drugs, hormonal therapy, physiotherapy techniques, etc., are the main treatments. The main objective of this study is to evaluate the effectiveness of transcutaneous posterior tibial nerve stimulation (TTNS) in PD patients. The study will consist of a single-blind randomized clinical trial, parallel-assigned with two arms. Women with PD (18-43 years) with regular menstrual cycles and at least 4 points in VAS will be randomly divided into experimental (TTNS) and placebo (simulated stimulation) groups during 12 treatment sessions (1 session/week) and several follow-ups: monthly during treatment and 1, 3 and 6 months after. Maximum and mean pain intensity, pain duration, pain severity, number of anti-inflammatory drugs, quality of life, sleep quality, overall improvement, treatment satisfaction and secondary effects will be measured once a month every 6 months and at 3 and 6 months. The Student's t-test for independent samples or the Mann-Whitney U test will be used. The literature shows effective physiotherapeutic techniques for PD in the short term, which do not act on causes and have limitations. The TTNS technique can be used in transcutaneous and percutaneous modalities, with similar effectiveness, but the transcutaneous causes less discomfort. TTNS modulates pain, and long-term benefits could be achieved at low cost and without patient discomfort.

Comparison of Connective Tissue Massage and Classic Massage in Women With Primary Dysmenorrhea: A Randomized Clinical Trial

OBJECTIVE

The purpose of this study was to compare the short-term effects of connective tissue massage (CTM) and classic massage (CM) on pain, functional and emotional status, and menstrual complaints in women with primary dysmenorrhea (PD).

METHODS

Women with PD were randomly assigned to 2 groups: CTM (n = 19) and CM (n = 19). CTM or CM was applied 5 days a week from the estimated date of ovulation to the onset of the next menstruation. The pain intensity with the Visual Analog Scale and functional and emotional status with the Functional and Emotional Dysmenorrhea Scale (FEDS) were assessed before and after the applications. Pain duration and the presence of menstrual complaints were recorded.

RESULTS

In the postintervention period, both groups had decreased menstrual pain intensity and duration, drug use, and FEDS scores (P < .001). Pain duration and FEDS-functional scores decreased more in the CTM group than in the CM group (P < .05). Moreover, in the postintervention period, fewer women were nervous in the CM group, whereas low back pain, constipation, and sleeplessness were less frequent in the CTM group, compared with their preintervention period (P < .05). A difference was observed between groups only in terms of the changes in sleeplessness between before and after intervention (P = .016).

CONCLUSION

CTM and CM improved menstrual pain and functional and emotional status, and decreased drug use. Moreover, CTM was superior in improving pain duration, functional status, and sleeplessness compared with CM in PD. CTM and CM might be useful treatment methods for PD.

Effects of Kinesio Taping method on menstrual pain: A randomized, single-blind, placebo-controlled crossover study

Current research promotes complementary methods of coping with menstrual pain (MP). Our objective was to examine the effectiveness of the Kinesio Taping (KT) intervention on MP and determine whether KT has therapeutic impact or whether there is presence of placebo. We used crossover design, dividing 30 female participants into KT and placebo KT groups. Every phase included one menstrual cycle. The average age of participants was 23.5 years (ranging from 18 to 39 years). In the assessment, we used VAS, Brief Pain Inventory Scale, and some SF-36 subscales. In KT phase all types of pain (the average MP, the worst experienced MP, the mildest one, and the current MP) were significantly less intense. KT has beneficial effect in reducing MP and its consequences and it is significantly superior to placebo. The order of intervention showed no statistical significance, which also confirms the therapeutic effect of KT.

Auricular therapy for primary dysmenorrhea: A protocol for systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Primary dysmenorrhea (PD) is a common problem among women. It is defined as any degree of perceived cramping pain during menstruation without any evident pathology. Auricular therapy (AT), a widely used alternative medical treatment method as part of traditional Chinese acupuncture, lacks reliable evidence to support its safety and effectiveness for PD. We aimed to conduct a meta-analysis to investigate the efficacy and safety of AT in PD and to investigate possible factors impacting the particular efficacy of AT in PD by meta-regression.

METHODS

This protocol followed the PRISMA guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. The following 9 sources will be searched for randomized control trials of AT for PD: the Cochrane Central Register of Controlled Trials, PubMed, Medline, Embase, Web of Science, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure, Chinese Science and Technology Periodicals (VIP) database and WanFang Database from inception to January 1, 2023. Primary outcomes include visual rating scales and clinical efficacy rates, while secondary outcomes include endocrine hormone indicators related to PD and adverse events. Two reviewers will work independently on study selection, data extraction, and coding, including the risk of bias assessment in the included studies. While conducting a meta-analysis, Review Manager version 5.3 will be employed. Otherwise, a descriptive analysis will be performed. The results will be displayed as a risk ratio with 95% confidence intervals for dichotomous data as well as weight mean difference or standardized mean difference with 95% confidence intervals for continuous data.

RESULTS

This study's protocol will investigate the efficacy and safety of AT in the treatment of PD in a systematic way.

CONCLUSION

This systematic evaluation will objectively and systematically assess the efficacy and safety of AT in PD based on the available evidence, as well as provides clinicians with evidence to support the treatment of the disease.

Metabolomic study combined with the low-level light therapy of Chinese acupuncture points and combined oral contraceptives in treatment of primary dysmenorrhea: A prospective, multicenter, randomized controlled study

Objective

To compare the changes of metabolites between Low-level light therapy (LLLT) and combined oral contraceptive (COC) after treatment of primary dysmenorrhea (PD), and to compare and analyze the biological and biochemical effects of the two treatments by analyzing the differences in metabolite profiles.

Methods

A multicenter, double-blind, prospective, parallel, randomized controlled study was conducted on 69 women aged 16-35 years old with PD who were randomly divided into COC treatment group or LLLT treatment group. Low-level light therapy with light-emitting diodes (LED) was applied on two acupoints named "Guanyuan" (CV4) and "Qihai" (CV6). After 12 weeks of treatment intervention, blood samples were collected before and after treatment for metabolomic analysis. We used UPLC-MS/MS analysis to compare the differences in metabolite changes between LLLT and COC before and after treatment.

Results

76 differential metabolites were detected in the LLLT group, and 92 differential metabolites were detected in the COC group, which were up-regulated or down-regulated (p < 0.001). Prostaglandin D2 (PG D2) was down-regulated and biliverdin was up-regulated after LLLT treatment, 4a-Hydroxytetrahydrobiopterin, Prostaglandin D2, 5-Hydroxy-l-tryptophan, Cholic acid were down-regulated and cortisol was up-regulated after COC treatment, and the differences were statistically significant. Cortisol and testosterone glucuronide in LLLT group were significantly lower than those in COC group. The metabolic pathways affected were glycerophospholipid metabolism, linoleic acid metabolism and arachidonic acid metabolism in the LLLT group, and glycerophospholipid metabolism, folate biosynthesis, arachidonic-acid-metabolism, and tryptophan metabolism in the COC group. The differential metabolic pathway were linoleic acid metabolism, steroid hormone biosynthesis, and alpha-Linolenic acid metabolism after the comparison of LLLT with COC.

Conclusion

LLLT and COC might relieve dysmenorrhea by down-regulating PGD2, and LLLT might also relieve dysmenorrhea by up-regulating biliverdin. The level of cortisol and testosterone glucuronide after LLLT treatment was lower than that after COC treatment, which might lead to the difference in the clinical efficacy of the two treatments for dysmenorrhea.

Benefits of physical therapy in improving quality of life and pain associated with endometriosis: A systematic review and meta-analysis

OBJECTIVE

To assess whether non-pharmacologic conservative therapeutic interventions are beneficial in improving pain intensity and quality of life in women with endometriosis compared with placebo.

METHODS

A systematic review with meta-analysis was designed. A literature search was performed in the following databases: PubMed, PEDro, Embase, CINAHL, Isi Web of Science, Enfispo, and Cochrane. Randomized controlled trials included women with endometriosis treated with conservative treatment versus placebo. The quality of the studies was assessed using the PEDro scale, and the risk of bias of the individual studies was assessed using the Cochrane Risk of Bias tool. For the overall quality of the studies, the GRADE guidelines were used.

RESULTS

Meta-analysis included six studies. Significant results were obtained for pain intensity (standardized mean difference [SMD] -0.89; 95% confidence interval [CI] -1.21 to -0.57; I² 69%) and concerning quality of life, significant results were only obtained for the sub-variable physical function (SMD -1.49; 95% CI -2.88 to -0.10; I² 95%). No statistically significant differences were found for the rest of the variables analyzed.

CONCLUSION

Non-pharmacologic conservative therapies are a therapeutic option for women with endometriosis for improving pain intensity and physical function.

Myofascial Pain Syndrome in Women with Primary Dysmenorrhea: A Case-Control Study

There is limited information on myofascial trigger points (MTrPs) and specific symptoms of chronic pelvic pain and, more specifically, dysmenorrhea. The objective of this study was to determine whether patients suffering from primary dysmenorrhea present alterations in mechanosensitivity and pain patterns, and greater presence of MTrPs in the abdominal and pelvic floor muscles. A case-control study was carried out with a total sample of 84 participants distributed based on primary dysmenorrhea and contraceptive treatment. The sample was divided into four groups each comprising 21 women. Data on pain, quality of life, and productivity and work absenteeism were collected; three assessments were made in different phases of the menstrual cycle, to report data on pressure pain threshold, MTrP presence, and referred pain areas. One-way ANOVA tests showed statistically significant differences (p < 0.01) between the groups, for the Physical Health domain and the total score of the SF-12 questionnaire, and for all the domains of the McGill questionnaire; but no significant differences were found in the data from the WPAI-GH questionnaire. Statistically significant data (p < 0.01) were found for mechanosensitivity in the abdominal area and limbs, but not for the lumbar assessment, within the group, with very few significant intergroup differences. The frequency of active MTrPs is higher in the groups of women with primary dysmenorrhea and during the menstrual phase, with the prevalence of myofascial trigger points of the iliococcygeus muscle being especially high in all examination groups (>50%) and higher than 70% in women with primary dysmenorrhea, in the menstrual phase, and the internal obturator muscle (100%) in the menstrual phase. Referred pain areas of the pelvic floor muscles increase in women with primary dysmenorrhea.

Myofascial Trigger Points and Central Sensitization Signs, but No Anxiety, Are Shown in Women with Dysmenorrhea: A Case-Control Study

Background primary dysmenorrhea (PD) is considered to be a cyclic chronic pelvic pain, with its onset in menstrual periods, often accompanied by the presence of myofascial trigger points (MTP). Most MTPs in subjects with chronic pelvic pain are in the inferior part of the abdomen, in the rectus abdominis (RA) area. Central sensitization is closely related to chronic pain processes. Previous studies in women with chronic pelvic pain reported central sensitization signs in their subjects, such as lower pain pressure threshold (PPT). Several authors agree that PPT in the tibialis anterior (TA) muscle, seems to be a reliable reference for signs of central sensitization. Amongst the factors that seem to accompany central sensitization, the presence of anxiety needs to be considered. The aim of the present study was to analyze the existence of hyperalgesic MTPs in RA, central sensitization signs and anxiety in women with PD, in comparison with a control group (CG). Methods: This study was designed following an observational, cross-sectional, case-control model. A total sample of 80 subjects was recruited trough social webs and advertising (PD n = 39) (CG n = 41). PPT in RA and AT was assessed bilaterally through algometry, and anxiety was evaluated through the State−Trait Anxiety Inventory. Results: Statistically significant differences (p < 0.001) were shown for NRS average and maximum increase, as well as lower bilaterally RA and TA PPT in favor of PD group compared to CG. State or trait STAI did not show any statistically significant differences (p > 0.05) between groups. Conclusions: In this study, women with PD reported symptoms of myofascial pain syndrome and central sensitization, when compared with healthy controls, without any sign of anxiety acting as a confounder for pain sensitivity.

Safety and efficacy of therapeutic taping in primary dysmenorrhea: a systematic review and meta-analysis

Primary dysmenorrhea (PD) is a common gynecological condition among adolescent and adult women. Several pharmacological and alternative therapies (e.g. therapeutic taping) have been used to treat PD, with varying effect. This systematic review and meta-analysis was performed to evaluate the safety and efficacy of therapeutic taping on clinical symptoms of PD, considering pain as the primary outcome. MEDLINE, Cochrane Library, Embase, PEDro, CINAHL and gray literature sources were searched from inception to February 2022 for randomized controlled trials (RCTs) that assessed the effect of therapeutic taping for PD. The language was restricted to English. A total of ten studies were included in the systematic review, involving 685 participants. Eight studies were included in quantitative analysis. The quality of the studies ranged from 4 to 7 with a median of 5 as assessed by PEDro scale. Meta-analyses indicated short-term improvements of pain compared to sham and no interventions. Elastic therapeutic taping (ETT) indicated short term improvements in anxiety associated with PD. Moderate to high quality of evidence suggested that ETT is an effective intervention in improving pain, anxiety, and quality of life of women with PD. A scarcity of evidence on the long-term effects of therapeutic taping in PD is observed.

Dysmenorrhea in adolescents

Studies show that between 41% and 91.5% of young women, school-aged and university-aged, are affected by dysmenorrhea. Primary dysmenorrhea, which is caused by the production of prostaglandins, is defined as cramping pain in the lower abdomen and/or pelvis occurring just before or during menstruation, in the absence of other diseases such as endometriosis, and typically lasting 1-3 days and with a negative physical examination. Secondary dysmenorrhea presents with similar signs and symptoms but is a result of underlying pelvic pathology, for example endometriosis or uterine fibroids. Dysmenorrhea most typically presents as abdominal cramping; however, it can also present with headaches, nausea, vomiting or other generalized symptoms. The diagnosis is mainly clinical, but other tests such as a pelvic examination, a pregnancy test and STI screening may be helpful in ruling out other sources of pain. Although the mainstay of treatment for dysmenorrhea is NSAIDs and hormonal therapy, lifestyle changes and complementary/alternative medicine can also be helpful approaches. Lifestyle changes include aerobic exercise and stretching, while complementary alternative medicine include peppermint, cinnamon, ginger and other herbs and supplements. Finally, endometriosis must be considered as a potential cause for secondary dysmenorrhea and would warrant a prompt referral to gynecology.

Effect of non-pharmacological interventions on anxiety, depression, sleep quality, and pain after orthopedic surgery: A protocol for systematic review and network meta-analysis

BACKGROUND

Patients after orthopedic surgery often experience the pain, anxiety, depression, and sleep disturbances, which can be greatly reduced by non-pharmacologic interventions as alternative therapies. Randomized controlled trials of nonpharmacologic interventions for anxiety, depression, sleep quality, and pain in patients after orthopedic surgery have been reported, but the results may be conflicting. Evidence to determine the optimal non-pharmacological intervention with a high efficacy is limited. This study aims to assess the effects of non-pharmacologic interventions on the bone anxiety, depression, sleep quality, and pain in patients after orthopedic surgery through a network meta-analysis, thus providing guidance in clinical application.

METHODS

A systematic search of randomized controlled trials reporting the effects of non-pharmacological interventions on anxiety, depression, sleep quality and pain after orthopedic surgery published before October 2021 will be searched in Wanfang, VIP Information Chinese Journal Service Platform, China National Knowledge Infrastructure, Chinese BioMedicine Literature Database, Pubmed, Embase, Cochrane, and Web of science. Two reviewers will be independently responsible for study selection, quality appraisal, and data extraction. Stata 14.0 software will be used to perform the network meta-analysis.

RESULTS

The findings of this research will be reported in a recognized journal.

CONCLUSION

This meta-analysis will provide the stronger evidence for non-pharmacological interventions on alleviating bone anxiety, depression, sleep quality, and pain in patients after orthopedic surgery, which will help clinicians and decision makers in their choices.Open Science Framework registration number: DOI 10.17605/OSF.IO/2SCBD.
