Decreased ankle range of motion (ROM) leads to many disorders, ranging in severity from gait abnormalities to knee and pelvis injuries. Therefore, maintaining full ankle ROM is very important, especially for athletes, for whom ankle ROM may affect their results during competitions. Medical flossing is a technique used by physiotherapists to improve ROM. The aim of this review was to investigate the effect of medical flossing on ankle ROM according to the results in previous studies. ‪The search was conducted with the following key words individually and/or in combinations: range of motion, flossband, mobility bands, vascular occlusion, flossing bands, compression, voodoo floss, and tack floss. F‪rom the identified 5600 articles, only 4 studies were included in this systematic review. The results showed that the mean difference in ROM after treatment was 1.20 cm (Hedge’s g = 0.31, p < 0.01, I2= 89%). ‪There is evidence showing that the application of flossing can be beneficial to increase the ROM. Moreover, some of the studies confirmed a positive impact of flossing on jump performance; nonetheless, data to confirm this effect in this review are insufficient.

ObjectiveTo critically appraise the quality of published systematic reviews (SRs) of randomised controlled trials (RCTs) in tendinopathy with regard to handling and reporting of results with special emphasis on strength of evidence assessment.Data sourcesMedline from inception to June 2020.Study eligibilityAll SRs of RCTs assessing the effectiveness of any intervention(s) on any location of tendinopathy.Data extraction and synthesisIncluded SRs were appraised with the use of a 12-item tool devised by the authors arising from the Preferred Reporting Items in Systematic Reviews and Meta-Analyses statement and other relevant guidance. Subgroup analyses were performed based on impact factor (IF) of publishing journals and date of publication.ResultsA total of 57 SRs were included published in 38 journals between 2006 and 2020. The most commonly used risk-of-bias (RoB) assessment tool and strength of evidence assessment tool were the Cochrane Collaboration RoB tool and the Cochrane Collaboration Back Review Group tool, respectively. The mean score on the appraisal tool was 46.5% (range 0%–100%). SRs published in higher IF journals (>4.7) were associated with a higher mean score than those in lower IF journals (mean difference 26.4%±8.8%, p=0.004). The mean score of the 10 most recently published SRs was similar to that of the first 10 published SRs (mean difference 8.3%±13.7%, p=0.54). Only 23 SRs (40%) used the results of their RoB assessment in data synthesis and more than half (n=30; 50%) did not assess the strength of evidence of their results. Only 12 SRs (21%) assessed their strength of evidence appropriately.ConclusionsIn light of the poor presentation of evidence identified by our review, we provide recommendations to increase transparency and reproducibility in future SRs.

AbstractThe Nordic Hamstring exercise reduces hamstring strain injuries in football and other sports, but the exercise is not well adopted in practice. Barriers from practitioners include fear of performance decrements, due to lack of specificity of the exercise with high speed running. However, in theory, increased eccentric hamstring strength could transfer to faster sprinting due to higher horizontal force production. Studies on the effect of the Nordic Hamstring exercise on performance have been conflicting and no synthesis of the evidence exists. We therefore pose the following question: does including the Nordic Hamstring exercise hamper sprint or jump performance in athletes? We will answer this question by performing a systematic review of the literature, critically appraise relevant studies, and GRADE the evidence across key outcomes and perform meta-analyses, meta-regression and subgroup analyses. In this protocol we outline the planned methods and procedures.Progress reportBesides this protocol, our data extraction form and the process of data extraction has been piloted on 3 relevant studies, along with familiarization with the Risk of Bias 2.0 tool. We have also comprised a preliminary search strategy for PubMed.Supplementary filesData Extraction Form (.pdf)Populated PRISMA-P checklist (.pdf)

Background Prior studies have suggested aortic peak wall stress (PWS) and peak wall rupture index (PWRI) can estimate the rupture risk of an abdominal aortic aneurysm (AAA), but whether these measurements have independent predictive ability over assessing AAA diameter alone is unclear. The aim of this systematic review was to compare PWS and PWRI in participants with ruptured and asymptomatic intact AAAs of similar diameter. Methods and Results Web of Science, Scopus, Medline, and The Cochrane Library were systematically searched to identify studies assessing PWS and PWRI in ruptured and asymptomatic intact AAAs of similar diameter. Random‐effects meta‐analyses were performed using inverse variance‐weighted methods. Leave‐one‐out sensitivity analyses were conducted to assess the robustness of findings. Risk of bias was assessed using a modification of the Newcastle‐Ottawa scale and standard quality assessment criteria for evaluating primary research papers. Seven case‐control studies involving 309 participants were included. Meta‐analyses suggested that PWRI (standardized mean difference, 0.42; 95% CI, 0.14–0.70; P =0.004) but not PWS (standardized mean difference, 0.13; 95% CI, −0.18 to 0.44; P =0.418) was greater in ruptured than intact AAAs. Sensitivity analyses suggested that the findings were not dependent on the inclusion of any single study. The included studies were assessed to have a medium to high risk of bias. Conclusions Based on limited evidence, this study suggested that PWRI, but not PWS, is greater in ruptured than asymptomatic intact AAAs of similar maximum aortic diameter.

Study Design Systematic review and meta-analysis Objectives The present review aimed to summarize the evidence regarding differences in proprioception between children with and without adolescent idiopathic scoliosis (AIS). Methods Seven electronic databases were searched from their inception to April 10, 2021. Articles were included if they involved: (1) AIS patients aged between 10 and 18 years, (2) measurements of proprioceptive abilities, and (3) comparisons with non-AIS controls. Animal studies, case reports, commentaries, conference proceedings, research protocols, and reviews were excluded. Two reviewers independently conducted literature screening, data extraction, risks of bias assessments, and quality of evidence evaluations. Relevant information was pooled for meta-analyses. Results From 432 identified citations, 11 case-control studies comprising 1121 participants were included. The meta-analyses showed that AIS participants displayed proprioceptive deficits as compared to non-AIS controls. Moderate evidence supported that AIS participants showed significantly larger repositioning errors than healthy controls (pooled mean difference = 1.27 degrees, P < .01). Low evidence substantiated that AIS participants had significantly greater motion detection threshold (pooled mean difference = 1.60 degrees, P < .01) and abnormal somatosensory evoked potentials (pooled mean difference = .36 milliseconds, P = .01) than non-AIS counterparts. Conclusions Consistent findings revealed that proprioceptive deficits occurred in AIS patients. Further investigations on the causal relationship between AIS and proprioception, and the identification of the subgroup of AIS patients with proprioceptive deficit are needed.

Background. An increase in the mean platelet volume (MPV) has been proposed as a novel prognostic indicator in critically ill patients.Objective. We conducted a systematic review and meta-analysis to determine whether there is an association between MPV and mortality in critically ill patients.Methods. We did electronic search in Medline, Scopus, and Embase up to November 2015.Results. Eleven observational studies, involving 3724 patients, were included. The values of initial MPV in nonsurvivors and survivors were not different, with the mean difference with 95% confident interval (95% CI) being 0.17 (95% CI: −0.04, 0.38;p=0.112). However, after small sample studies were excluded in sensitivity analysis, the pooling mean difference of MPV was 0.32 (95% CI: 0.04, 0.60;p=0.03). In addition, the MPV was observed to be significantly higher in nonsurvivor groups after the third day of admission. On the subgroup analysis, although patient types (sepsis or mixed ICU) and study type (prospective or retrospective study) did not show any significant difference between groups, the difference of MPV was significantly difference on the unit which had mortality up to 30%.Conclusions. Initial values of MPV might not be used as a prognostic marker of mortality in critically ill patients. Subsequent values of MPV after the 3rd day and the lower mortality rate unit might be useful. However, the heterogeneity between studies is high.

This systematic review examines the efficacy of oral ginger for dysmenorrhea. Key biomedical databases and grey literature were searched. We included randomized controlled trials comparing oral ginger against placebo or active treatment in women with dysmenorrhea. Six trials were identified. Two authors independently reviewed the articles, extracted data, and assessed risk of bias. Discrepancies were resolved by consensus with a third reviewer. We completed a narrative synthesis of all six studies and exploratory meta-analyses of three studies comparing ginger with placebo and two studies comparing ginger with a nonsteroidal anti-inflammatory drug (NSAID). Ginger appeared more effective for reducing pain severity than placebo. The weighted mean difference on a 10 cm visual analogue scale was 1.55 cm (favoring ginger) (95% CI 0.68 to 2.43). No significant difference was found between ginger and mefenamic acid (an NSAID). The standardized mean difference was 0 (95% CI −0.40 to 0.41). Available data suggest that oral ginger could be an effective treatment for menstrual pain in dysmenorrhea. Findings, however, need to be interpreted with caution because of the small number of studies, poor methodological quality of the studies, and high heterogeneity across trials. The review highlights the need for future trials with high methodological quality.

Upper Extremity Injury

Context: Current perception dictates that glenohumeral internal rotation deficit (GIRD) is a chronic adaptation that leads to an increased risk of pathologic conditions in the dominant shoulder or elbow of overhead athletes. Objective: To determine whether adaptations in glenohumeral range of motion in overhead athletes lead to injuries of the upper extremity, specifically in the shoulder or elbow. Data Sources: An electronic database search was performed using Medline, Embase, and SportDiscus from 1950 to 2016. The following keywords were used: GIRD, glenohumeral internal rotation deficit, glenohumeral deficit, shoulder, sport, injury, shoulder joint, baseball, football, racquet sports, volleyball, javelin, cricket, athletic injuries, handball, lacrosse, water polo, hammer throw, and throwing injury. Study Selection: Seventeen studies met the inclusion criteria for this systematic review. Of those 17 studies, 10 included specific range of motion measurements required for inclusion in the meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 4. Data Extraction: Data on demographics and methodology as well as shoulder range of motion in various planes were collected when possible. The primary outcome of interest was upper extremity injury, specifically shoulder or elbow injury. Results: The systematic review included 2195 athletes (1889 males, 306 females) with a mean age of 20.8 years. Shoulders with GIRD favored an upper extremity injury, with a mean difference of 3.11° (95% CI, –0.13° to 6.36°; P = 0.06). Shoulder total range of motion suggested increased motion (mean difference, 2.97°) correlated with no injury ( P = 0.11), and less total motion (mean difference, 1.95°) favored injury ( P = 0.14). External rotational gain also favored injury, with a mean difference of 1.93° ( P = 0.07). Conclusion: The pooled results of this systematic review and meta-analysis did not reach statistical significance for any shoulder motion measurement and its correlation to shoulder or elbow injury. Results, though not reaching significance, favored injury in overhead athletes with GIRD, as well as rotational loss and external rotational gain.

Background and Hypothesis: At the graduate and professional level, computer-aided instruction demonstrated a positive impact on knowledge gains when supplementing traditional teaching methods (Wilson et al). The present research sought to determine the efficacy of supplementing traditional pedagogical methods in an undergraduate anatomy lab with VH Dissector Software (VHD) on a large touchscreen terminal. Experimental Design or Project Methods: Throughout Basic Human Anatomy (ANAT-A215), students took a pre-quiz before covering a topic followed by a post-quiz in the next class. Using VHD was the intervention, while using the traditional lab manual, models, and two prosected cadavers was the control. The mean difference between pre-test and post-test scores was calculated. Independent Samples T Tests compared the mean difference between intervention and control groups. Post-course surveys were obtained. Calculations were made of frequencies for each question and Spearman Rho correlations between questions. Results: There was significant improvement in scores with the intervention (versus control) in the Spring 2019 semester (Meanintervention = 1.13, Meancontrol = 0.92, P <0.01). In the post-course survey, 54.1% of students indicated that they would not recommend using VHD in future semesters. Among these students, 50.1% stated they did not find VHD beneficial, 34% stated VHD helped to rotate structures, and 23.4% stated VHD was a change of pace from other lab responsibilities. Among the students that recommend using VHD, 64.8% stated VHD helped to rotate structures, 51.4% stated VHD provided context for what they saw on models, and 48.9% stated that VHD was a change of pace from other lab responsibilities. A significant correlation was found between enjoying use of the VHD and perception of learning using VHD (r = 0.794, P <0.01) Conclusion and Potential Impact: These results indicate a benefit to supplementing traditional anatomy learning modalities with dissection software at the undergraduate level. Yet, while students recognize a benefit, they often recommended not using the tech in future semesters.

Background: Acne vulgaris (AV) is a chronic inflammatory disease of the pilosebaceous follicular unit that often occurs. Acne is a skin disorder that is not life-threatening but is mostly complained of because it is aesthetically disruptive, which can cause significant psychological problems for sufferers. The management of acne vulgaris in female patients has its challenges. There are many histories of failed therapy using conventional therapy, such as with antibiotics or isotretinoin, and female patients have a predisposition to the condition of androgen excess. Also, the increasing awareness about limiting the use of antibiotics to prevent resistance in dermatological cases, including acne vulgaris, encourages other treatment options in the female patient population, one of which is hormone-based therapy. A systematic review and meta-analysis were performed of randomized clinical trials assessing the effects of Hormone Based Therapies (Spironolactone and Combined Oral Contraceptives) in the management of Acne Vulgaris in Women. Methods: Medline Pubmed, Scopus, Cochrane Library, the reference list, conference proceedings, researchers in the field of eligible studies were searched. Ten studies (n=1906 sub-jects) were included in qualitative analysis, of which two studies (n=1842 subjects) were included in the meta-analysis. The age of the participant was greater than 14 years old. Intervention using combined oral contraceptives (n=8) or oral spironolactone (n=2). Duration of intervention (minimum six months for COC and three months for SL) and out-comes of mean difference number of acne vulgaris lesions before and after treatment. Results: Pooling of data using random-effects model found a significant difference in the mean difference in the number of lesions after treatment in the group receiving hormone-based therapy (spironolactone and combined oral contraceptives) and those receiving control therapy (p = 0.005). The overall mean difference was -0.890 ± 0.316. A negative value indicating the number of lesions after hormone-based therapy (spironolactone and combined oral contraceptives) was significantly lower than those receiving control therapy (p = 0.005). Conclusion: From the results of the systematic review and meta-analysis conducted, it can be concluded that in the group given hormone-based therapy (spironolactone and Combined Oral Contraceptives), there was a decrease in the total number of acne vulgaris lesions compared to before treatment, and the mean difference in the number of lesions was significantly lower after getting hormone-based therapy (spironolactone and combined oral contraceptives) compared with controls.
