Clinical usability study of a home-based self-administration transcranial direct current stimulation for primary dysmenorrhea: A randomized controlled trial.

This study tested the usability of a home-based self-administration transcranial direct current stimulation (tDCS) device designed specifically for women's health needs. This is a single center triple blinded clinical usability study for a new wireless, Bluetooth-controlled wearable tDCS device for women's health. The study aims to evaluate the usability and effective blinding of a home-based tDCS system. A total of forty-nine women of reproductive age were randomly allocated (1:1) to receive one session of active tDCS (n = 24) or sham tDCS (n = 25) over the motor and dorsolateral prefrontal cortex. Each participant self-administered one 20-minute session without supervision following guidance on a software application alone. The System Usability Scale (SUS) and the Patient Global Impression of Change (PGIC) were used to evaluate the usability of the system. Regardless of sham or active conditions, all users found the system easy to use without the support of researchers. Usability scores were considered to be "excellent" in both groups and no significant difference was found between sham and active groups showing effective blinding of the device (Active group: 93.7 (83.1-97.5); Sham group 90 (86.2-95) p = 0.79) and PGIC (Active group: 2 (1-2.75); Sham group 2 (1-2) p = 0.99) using an unpaired t-test or non-parametric statistical tests accordingly. The new Bluetooth-controlled wearable tDCS device is easy, safe to use and completely controlled by a smartphone app. This device is focused on women's health and will be tested as an alternative treatment for chronic pelvic pain and mood disturbance associated with menstrual cycles in further research.

Are women with endometriosis more likely to experience reduced physical performance compared to women without the condition?

Background: Endometriosis is a condition of the female reproductive system associated with pelvic pain. Chronic pain can affect physical performance by limiting the functional activities, thus, it is hypothesized that women with endometriosis may also present decreased functional capacity, decreased strength, and mobility. The objective of this study is to compare physical performance in women with and without endometriosis. Methods: This is a cross-sectional study composed of 115 women equally divided into two groups: the endometriosis group (EG), composed of women with a confirmed diagnosis of the disease by magnetic resonance imaging, and the comparator group (CG), consisting of women without suspicion of the disease. Physical performance (dependent variable) was assessed using hand dynamometry, the 6-min walk test (6MWT), gait speed, and the chair stands test. CG participants performed the tests during the luteal phase of the menstrual cycle. Descriptive statistics, unpaired t-tests, and chi-square tests were used to describe and compare the groups. Multiple linear regression tested the associations adjusted for covariates (age, income, education, age at menarche, and body mass index). Results: The EG had worse gait speed (mean difference: -0.11; 95% CI: [-0.18 to -0.04]), weaker grip strength (mean difference: -3.32; 95% CI: [-5.30 to -1.33]), shorter distance covered in the 6MWT (mean difference: -83.46; 95% CI: [-121.38 to -45.53]), and a lower number of repetitions in the chair stands test (mean difference: -8.44; 95% CI: [-10.64 to -6.25]) than the CG, even after adjusting for covariates. Conclusion: Grip strength, lower limb strength, mobility, and functional capacity were worse in women diagnosed with endometriosis. Women with endometriosis should be encouraged to engage in physical exercise, adopt healthy lifestyle habits, and participate in rehabilitation activities to control pain, with the aim of reducing functional impairments.

Effects of photobiomodulation therapy on the functional performance of healthy individuals: a systematic review with meta-analysis.

The aim of this study is to assess the effect of photobiomodulation therapy (PBMT) on functional performance concerning strength, fatigue, and functional capacity in healthy individuals. This systematic review with meta-analysis involved searches on data platforms and active searches of randomized clinical trials, focusing on PBMT as the sole intervention. Primary outcomes assessed included strength, fatigue, and functional capacity. Three reviewers screened studies by title and abstract using Rayyan, and data were extracted using a specific form. Bias risk was assessed using RoB2, and confidence in the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The RevMan was used for meta-analysis. Sixteen studies were included, totaling 340 individuals (183 males and 157 women). Most articles presented a low risk of bias. Variability was observed in device types and application domains, including wavelengths (655-905 nm), power (10-200 nW), energy (0.6-30 J per point), and time (30-100 s per point). PBMT improved fatigue recovery (mean difference: 5.87; 95% CI 3.83, 7.91). There was no enhancement in strength (peak torque: mean difference 12.40; 95% CI -5.55, 30.55; one-repetition maximum test: mean difference 39.97, 95% CI -2.44, 82.38; isometric and isokinetic strength: mean difference 2.77, 95% CI -14.90, 20.44) nor improvement in short-term (mean difference 0.67, 95% CI -0.58, 1.91) and long-term (mean difference 18.44, 95% CI -55.65, 92.54) functional capacity. PBMT may aid in favoring fatigue recovery in healthy individuals; however, there's no evidence to support PBMT enhancing strength or improving functional capacity.

A Health App for Evidence-Based Postpartum Information: Development and Validation Study.

BACKGROUND: After childbirth, women undergo substantial physical and emotional changes. Therefore, it is important to provide them with information that helps them identify what is expected during this stage, as well as signs and symptoms that indicate complications after they have been discharged from the hospital. OBJECTIVE: This study aimed to develop a health app-Towards Motherhood-that provides evidence-based information about the postpartum period and evaluate the usability of the app with the target population. METHODS: This was a validation study involving 80 participants, including 24 professionals from the obstetric health field, 15 professionals from the technology field, and 41 postpartum women. The app was developed using React Native technology. Health professionals evaluated the app's content using the Content Validity Index, technology professionals completed a validated evaluation to assess the appearance of the app, and postpartum women completed the System Usability Scale (SUS) to measure the usability of the app. RESULTS: The measurement of content validity using a Likert scale obtained an approval score of 99%. Regarding the app's appearance, 92% of responses were positive, reflecting favorable approval. The SUS usability score was 86.2, which represents excellent acceptance. CONCLUSIONS: The Towards Motherhood mobile app is a valid tool for promoting self-care during the postpartum period. The app's evidence-based information, user-friendly design, and high usability make it an essential resource for women during this critical stage of their live.

Chronic Chikungunya arthralgia reduces functionality, quality of life and occupational performance: descriptive cross-sectional study / Artralgia crônica por Chikungunya reduz funcionalidade, qualidade de vida e performance ocupacional: estudo descritivo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Chikungunya virus (CHIKV) chronic polyarthralgia deteriorates general functionality and work productivity. The objective of this study was to evaluate functionality, pain, quality of life, and sleep quality of individuals with chronic CHIKV arthralgia and correlate them with clinical symptoms, work productivity, and activity impairment. METHODS: This is a descriptive cross-sectional study with 61 chronic CHIKV arthralgia patients. Functionality was assessed using the Health Assessment Questionnaire (HAQ). Pain intensity and interference were measured by using the Visual Analog Scale (VAS) and the Brief Pain Inventory Short Form (BPI), respectively. Quality of life and sleep were evaluated using the Short Form 36 Health Survey (SF-36) and the Pittsburgh Sleep Quality Index (PSQI), respectively. Work Productivity and Activity Impairment (WPAI) questionnaire was used to assess the effects of health in general symptoms on work. RESULTS: Low and moderate level of function was present in 39.4% and 55.7% of the sample, respectively. Moderate pain (5.57 ± 2.25), poor sleep quality (47.54%), and sleep disturbances (42.63%) were also observed. Pearson correlations showed significant correlation between absenteeism and presenteeism with HAQ scores (p = 0.03; r = 0.39 and p = 0.01; r = 0.43, respectively), BPI interference (p = 0.02; r = 0.41 and p = 0.001; r = 0.58, respectively) and SF-36 physical score (p = 0.007; r = -0.49 and p = 0.01; r = 0.58, respectively). Activity impairment showed a significant correlation with HAQ (p = 0.01; r = 0.44), BPI interference (p = 0.006; r = 0.5), SF-36 physical score (p = 0.01; r = -0.6) and SF-36 total score (p = 0.01; r = -0.44). Overall work productivity loss only correlated with BPI interference (p = 0.04; r = 0.37). CONCLUSION: These results suggest that CHIKV chronic arthralgia showed bilateral moderate pain in large joints that impacts activities of daily life, work productivity, and functional activity. HIGHLIGHTS Chronic chikungunya reduces functionality and causes moderate pain and poor sleep quality Clinical symptoms impact daily living activity, work productivity, and activity impairment. Functionality, pain, and sleep correlate with occupational performance.

Evaluation of the female pelvic floor with infrared thermography: a cross sectional study.

BACKGROUND: Infrared thermography (IRT) is an easy-to-use, noninvasive and pain-free tool that can be used to evaluate function of the pelvic floor (PF) muscles. OBJECTIVE: To analyze vaginal manometry, temperature, and percentage of colors achieved through IRT of the PF muscles at rest and during maximum voluntary contraction. The relationship between PF muscles strength and IRT temperature was also assessed. METHODS: Two-hundred and thirty-one women (mean ± SD age: 58.4±5.9 years) participated in this study. IRT recorded the minimum, average, and maximum temperatures, and the colors of the PF area at rest and during maximum voluntary contraction. The pressure applied during the three maximum voluntary PF contractions was evaluated through vaginal manometry. RESULTS: The women had a PF average temperature of 36.4 ± 0.8°C. There were no differences in the IRT temperatures between rest and during PF muscles contraction. The percentages of white, red, orange, yellow, green, cyan, and blue colors were different at rest and during contraction. Warm colors became more visible in the center of the image during the PF muscles maximum voluntary contraction. There was a positive correlation between the PF average temperature and PF manometry (r=0.7; p=0.001). CONCLUSION: The IRT was not able to detect differences in the temperature of the PF area between at rest and during contraction. However, a strong correlation between PF temperature and vaginal manometry was found.

Pelvic floor muscle training program for women in the puerperal period: clinical progress after intervention.

OBJECTIVE: To evaluate the sexual function of women in the puerperal period after a postpartum pelvic floor musculature training program. We also sought to evaluate correlations between sexual dysfunction in the women and their delivery type and compare the frequency of sexual dysfunction and the quality of resumed sexual function following vaginal and cesarean deliveries. METHODS: This clinical study included an intervention, carried out between July and December 2019, in which data were collected about 28 rooming-in women at a Maternity School. Data were divided into vaginal delivery and cesarean delivery. Sexual function was evaluated by the Female Sexual Function Index and the International Consultation on Incontinence Questionnaire-Short Form to assess the Incontinence Urinary and qualifies urinary loss. The intervention consisted of a muscle training exercise program. ANOVA tests were used to establish differences between groups. RESULTS: There was an improvement in all outcomes, but there was no time versus group interaction. Improvement in sexual function was observed (p<0.001), the impact of urinary incontinence on quality of life (p<0.001), and pressure of the muscles of pelvic floor muscles (p<0.001) over time. There was no time versus group interaction for sexual function (p=0.87), the impact of urinary incontinence on quality of life (p=0.88), and pressure of the pelvic floor muscles (p=0.66). CONCLUSIONS: Pelvic floor muscle exercise programs seem to be a very promising strategy concerning improving sexual activity among puerperal patients.

Evaluation of satisfaction of pelvic floor muscle training isolated and associated with tibial nerve stimulation in women with mixed urinary incontinence: A randomized, single-blinded clinical trial.

OBJECTIVES: To compare the satisfaction degree and pelvic floor manometry after pelvic floor muscle training isolated and associated with tibial nerve stimulation in women with mixed urinary incontinence (MUI). STUDY DESIGN: A randomized, single-blinded clinical trial was conducted. 24 women diagnosed with MUI were equally divided into two groups: pelvic floor muscle training isolated and associated to transcutaneous tibial nerve stimulation (TTNS). The study occurred in four stages: 1) evaluation: general information, pelvic floor manometry, the International Consultation on Incontinence Questionnaire - Urinary Incontinence - Short Form (ICIQ-UI-SF) and International Consultation on Incontinence Questionnaire - Overactive Bladder (OAB) application; 2) intervention: carried out over 2 months twice a week; 3) post-intervention evaluation: vaginal manometry, reapplication of the questionnaires and the Patient Global Impression (PGI) application at the end of the 2-month intervention; and, 4) follow-up: evaluation after 1 month of the end of the intervention. The primary outcome was the ICIQ-UI-SF and the secondary outcomes were ICIQ-OAB, vaginal manometry, and PGI. The repeated measures ANOVA was used to assess the time-to-group interaction by assigning a significance level of 5%. RESULTS: There was no interaction between time and group for ICIQ-UI-SF (p = 0.17) and manometry (p = 0.56). There was interaction for ICIQ-OAB (p < 0.01). PGI was reported as "much better" with 41.67% in the PFMTG + TTNS and 16.67% in the PFMTG after the intervention (p = 0.04). CONCLUSIONS: The results showed weak evidence that TTNS, in combination with PFMT, may be an intervention that can be used to treat MUI. The satisfaction degree was better with associated intervention.

Transcranial direct current electrical stimulation for the treatment of interstitial cystitis: A study protocol.

BACKGROUND: Interstitial cystitis or painful bladder syndrome is a chronic disorder that presents an unknown etiology, with no generally accepted treatment. Although there is no gold standard treatment, transcranial direct current stimulation (tDCS) has shown efficacy in several chronic pain syndromes with decrease in pain, and improved functionality and mood. tDCS could be a safe, ease to use, and low-cost complementary intervention for patients with interstitial cystitis. AIM: This study will investigate the effects of a tDCS protocol on pain, functionality, and mood in patients with interstitial cystitis. METHODS: A randomized controlled clinical trial with two arms. Women will be randomized into two groups: active or sham. Anodal tDCS over the primary motor cortex will be performed for 5 consecutive days with an intensity of 2 mA for 20 min. Participants will be evaluated five times: 1 week before intervention; on the 5th day of tDCS; and 1, 6, and 12 months after the last day of tDCS. The outcomes will be assessed using the numeric rating scale, McGill pain questionnaire, positive and negative affect scale, international consultation on incontinence questionnaire for female lower urinary tract symptoms, Hamilton anxiety scale, six-minute walk test, patient global impression of change, and voiding diary. DISCUSSION: Only the active group will be expected to show decreased pain. The results of this trial will be the first step in the use of neuromodulation in interstitial cystitis and will provide additional data to support new studies with tDCS.

Impact of Pelvic Floor Muscle Training Isolated and Associated with Game Therapy on Mixed Urinary Incontinence: A Randomized Controlled Trial.

Objective: To verify whether pelvic floor muscle training (PFMT) associated with game therapy (GT) can potentiate improvements in PFM pressure, urinary loss, and perception of improvement in women with mixed urinary incontinence (MUI). Materials and Methods: A randomized and blinded trial was conducted with 32 women aged between 45 to 70 years presenting diagnosis of MUI. They were randomly divided into two groups: PFMT group and PFMT+GT group. Interventions occurred twice a week during 8 weeks. Primary outcome was PFM pressure, assessed by manometry, and secondary outcomes were 1-hour pad-test, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and patients global impression of improvement for incontinence (PGI-I). Two-way analysis of variance and post hoc Tukey analysis were performed. Results: Initially, no significant difference between groups was found in variables of age, body mass index, educational level, marital status, gynecological and obstetric variables, life habits, and sexual activity. Besides, at baseline clinical variables also showed similar results between groups for PFM pressure, 1-hour pad-test, and ICIQ-SF. Time-group interaction did not present statistically significant differences for PFM pressure (P = 0.56), 1-hour pad-test (P = 0.75), and ICIQ-SF (P = 0.30) in intergroup analysis. All women reported being "much better or better," considering the comparison of urinary complaints in the beginning and end of treatment. Conclusion: There were no statistically significant differences between groups for PFM pressure, 1-hour pad-test, and ICIQ-SF. However, both treatments proved to be effective for MUI symptoms. Perception of improvement was highly improved, according to women's report.

Modulating Anxiety and Functional Capacity with Anodal tDCS Over the Left Dorsolateral Prefrontal Cortex in Primary Dysmenorrhea.

BACKGROUND: Primary dysmenorrhea is a common and often debilitating condition affecting 40-90% of menstruating women. This condition reduces functionality, quality of life, and social activities. Transcranial direct current stimulation (tDCS) has been used in many chronic pain syndromes, with evidence of improved pain, functionality, and mood in women with primary dysmenorrhea. The objective of this study was to determine whether tDCS could offer clinical benefits on pain, anxiety, affectivity, and functionality in women with primary dysmenorrhea. METHODS: This parallel, sham, randomized, double-blind trial was conducted with 26 women randomized into sham tDCS and active tDCS. Anodal tDCS was applied for 5 consecutive days over F3 corresponding to the left dorsolateral prefrontal cortex (DLPFC) and the cathode electrode over Fp2 for 20 min with an intensity of 2 mA. A numeric rating scale (NRS) was used to assess pain, anxiety, positive and negative affect, and submaximal aerobic performance during two consecutive menstrual cycles. RESULTS: No significant interaction was found between intervention and time on the NRS [F(2,44) = 1.358, p = 0.26], and a significant main effect of time [F(2,44) = 4.446, p = 0.01] was found. The active group showed a significant reduction in anxiety (p = 0.03) with a mean difference of 5.12 (95% CI 0.79 to 11.05). No significant differences in positive and negative affect were found (p = 0.95 and p = 0.15, respectively). Submaximal aerobic performance was significantly greater in the active group [F(2,21) = 5.591, p = 0.02], with a mean difference of 70.87 (95% CI 8.53 to 133.21). CONCLUSION: Anodal tDCS over the DLPFC seems to be an effective therapeutic approach for improving anxiety and functionality in women with primary dysmenorrhea.

Game therapy a new approach to treat women facing mixed urinary incontinence: A study protocol.

AIMS: To describe a pelvic floor muscle training (PFMT) isolated and associated with game therapy (PFMT + GT) for women facing mixed urinary incontinence (MUI) during climacteric period. METHODS: To standardize a randomized controlled clinical trial intervention, a protocol was created, in an attempt to decrease women's symptomatology generated by MUI, through pelvic floor and abdomino-loin-pelvic muscles strength, and endurance. This study protocol will be composed of 32 volunteers, divided into two groups of 16. They will perform PFMT isolated or PFMT + GT, twice a week during 8 weeks. Interventions will last 40 minutes and will be divided into warming (5 minutes), training (30 minutes), and 5 minutes will be composed of resting time between exercises (1 minute each). Isolated PFMT sessions will be performed through four modalities of exercises: diaphragmatic, bridge, abdominal (plank), and pelvic mobility. PFMT + GT training will be carried out by using Wii Fit Plus games, such as Lotus Focus, Penguin Slide, Basic Step, and Hula Hoop from Wii equipment. Assessments will occur before, after, and 1 month after interventions. Vaginal manometry, 1-hour Pad Test, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and Patient Global Intervention (PGI) will be used to evaluate the sample. CONCLUSIONS: It is expected greater increase on pelvic floor muscle (PFM) strength, endurance, vaginal pressure for PFMT + GG. Moreover, it is supposed that PFMT + GT volunteers present better treatment adherence due to games motivational inclusion.

Validation of the international consultation on incontinence modular questionnaire - female lower urinary tract symptoms (ICIQ-FLUTS) into brazilian portuguese

ABSTRACT Purpose: To translate, adapt and validate the International Consultation on Incontinence Modular Questionnaire on Female Lower Urinary Tract Symptoms ICIQ-FLUTS for the Brazilian female population. Materials and Methods: A translation of the questionnaire into Brazilian Portuguese was made followed by an adaptation for better understanding by native speakers. After that, the ICIQ-FLUTS was answered by eighty volunteers (n=80) twice (for interviewers 1 and 2) with an interval of 30 minutes between them. Furthermore, after 15 days from the evaluation, the participants answered the ICIQ-FLUTS again in order to verify the questionnaire stability over time. The questionnaires Utian Quality Of Life (UQOL) and International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), which are validated in Brazil were also applied to perform the validation. Results: The result of the Cronbach α coefficient of the instrument presented a value of 0.832. The values for test-retest were 0.907 (inter-observer) and 0.901 (intra-observer). The correlation between ICIQ-FLUTS (score I - domain of urinary incontinence) with the ICIQ-SF (final score) was strong and positive (r=0.836, p=0.000). In addition, the ICIQ-FLUTS showed moderate and negative correlation with the total score of UQOL (r=-0.691, p=0.017). Conclusion: The Portuguese version of the ICIQ-FLUTS questionnaire showed strong correlation to ICIQ-SF questionnaire and satisfactory values to test-retest and internal consistency.

Effects of Transcranial Direct Current Stimulation for Treatment of Primary Dysmenorrhea: Preliminary Results of a Randomized Sham-Controlled Trial.

OBJECTIVE: The aim of this trial was to investigate the effects of five consecutive sessions of anodal transcranial direct current stimulation (tDCS) over the motor cortex (M1) on pain, mood, and physical performance in patients with primary dysmenorrhea (PDM). DESIGN: This is a double-blind randomized controlled trial. SUBJECTS: Twenty-two participants with PDM according to the No. 345-PDM Consensus Guideline were included. METHODS: Eleven active treatment and 11 sham stimulation patients received five applications over a one-week period. The primary outcome measures were pain evaluated by numeric rating scale (NRS) and McGill Questionnaire score. Secondary outcomes measures were responses to the Positive and Negative Affect Schedule (PANAS), Hamilton Anxiety Scale (HAM-A), grip strength, and six-minute walk test (6MWT). Baseline data were performed during the first menstrual cycle, and during the second menstrual cycle, participants were conducted to tDCS treatment, and postintervention data were collected. RESULTS: The intervention provided significant improvements on NRS in active tDCS, shown as an interaction between group intervention vs pre/postintervention vs days of menstrual cycle (Wald x2 = 10.54, P = 0.005), main effect of days of menstrual cycle (Wald x2 = 25.42, P < 0.001), and pre/postintervention (Wald x2 = 6.97, P = 0.008). McGill showed an interaction effect between pre/postintervention and group of stimulation (Wald x2 = 18.45, P = 0.001), with a large reduction in active tDCS (P < 0.001, d = 0.75). Psychological and functional outcomes did not differ between groups or pre/postintervention. CONCLUSIONS: tDCS could provide pain relief in subjects with PDM. These results provide some preliminary evidence for the potential role of tDCS as a contributor to the management of symptoms of PDM.

Low-level laser therapy improves pain in postcesarean section: a randomized clinical trial.

This study aimed to evaluate the effect of low-level laser therapy (LLLT) on immediate postpartum pain relief during cesarean section. A randomized, parallel controlled trial was carried out. In total, 88 women with immediate postpartum were divided into 4 groups: control group (n = 22), placebo group (n = 22), experimental group I (n = 22, dose of 4 J/cm2), and experimental group II (n = 22, dose of 2 J/cm2). The pain measured by Numeric Rating Scale (NRS), algometry, and Global Change Perception Scale (GCPS) was assessed at 12, 20-24, and 44-48 h postpartum. Two LLLT sessions were performed at 12 and 24 h postpartum. A significant interaction was observed between time versus group for NRS F (2.40) = 36.80, p < 0.001 and algometry F (1.70) = 27.18, p < 0.001. GCPS revealed a significant difference between the groups during second (p = 0.04) and third evaluation (p = 0.04). The NRS and algometry presented a large effect size for the experimental groups. LLLT is an efficient method to reduce pain and enhance the GCP in postcesarean section. No significant clinical differences were found between the laser doses.
