Role of the kinetic chain in shoulder rehabilitation: does incorporating the trunk and lower limb into shoulder exercise regimes influence shoulder muscle recruitment patterns? Systematic review of electromyography studies

ObjectiveTo investigate the influence of trunk and lower limb motion on electromyography (EMG) muscle activity and recruitment patterns around the shoulder.DesignSystematic review.Data sourcesMEDLINE, CINAHL, PEDro, AMED, PubMed, Cochrane Central Register of Controlled trials, Cochrane Database of Systematic reviews, SportsDiscuss and PROSPERO.Eligibility criteriaStudies investigating both multiregional kinetic chain (KC) shoulder exercises and localised non-kinetic chain (nKC) shoulder exercises in healthy subjects under the same experimental conditions were included in this review.ResultsKC exercises produced greater EMG activation levels in 5 of 11 studies for the lower trapezius. Of the remaining studies, five found no difference between the exercise types and one favoured nKC exercises. KC exercises produced greater EMG activation levels in 5 of 11 studies for the serratus anterior. Of the remaining studies, three reported the opposite and three found no significant difference between the exercise types. nKC exercises produced greater EMG activation in infraspinatus in three of four studies. KC exercises produced the lowest trapezius muscle ratios in all studies. Studies investigating the upper trapezius, middle trapezius, supraspinatus, subscapularis, biceps brachii, latifissimus dorsi, pectoralis major, deltoid, and trapezius and serratus anterior ratios showed inconsistency.ConclusionThis review found evidence that integrating the KC during shoulder rehabilitation may increase axioscapular muscle recruitment, produce lower trapezius muscle ratios and reduce the demands on the rotator cuff. Stepping appears preferable to squatting.PROSPERO registration numberCRD42015032557, 2015.

BACKGROUND: Subacromial pain (SAP) is a common complaint of young athletes, independently of the sport engaged. The prevalence of SAP in some sports is up to 50%. OBJECTIVE: The study was aimed to investigate some new factors possibly associated to subacromial pain in young athletes. The factors considered were the grade of tightness of the clavicular portion of the pectoralis major, dysfunction of the sternoclavicular joint, and serratus anterior and lower trapezius strength. METHODS: This case-control study included 82 young athletes 9–15 years, 41 with the symptoms of SAP and 41 controls. All participants self-reported whether they had subacromial pain. In addition, Hawkins–Kennedy Test was performed to all the participants to evaluate the subacromial pressure. Main outcome measures were the grade of tightness of the clavicular portion of the pectoralis major, dysfunction of the sternoclavicular joint, and serratus anterior and lower trapezius strength. The grade of tightness of the clavicular portion of the pectoralis major and the dysfunction of the sternoclavicular joint were measured with an inclinometer. Serratus anterior and lower trapezius strength were measured by a handheld dynamometer with external belt-fixation. The data were analyzed using t-test for independent samples, Mann-Whitney U test, contingency coefficients and a stepwise binary logistic regression. RESULTS: Significant statistical difference was observed in the grade of tightness of the clavicular portion of the pectoralis major and in the variable representing the physiological functioning of the sternoclavicular joint, between the cases and the controls. There was no significant difference in serratus anterior and lower trapezius strength between the cases and the controls. Logistic regression analysis showed that the variable representing the physiological functioning of the sternoclavicular joint and the grade of shortening of the clavicular portion of the pectoralis major were good predictors for presence of SAP. CONCLUSIONS: A strong association was determined between subacromial pain in young athletes, clavicular portion of pectoralis major tightness and the dysfunction of the sternoclavicular joint.

Reducing unnecessary routine diagnostic testing has been identified as a strategy to curb wasteful healthcare. However, the safety and efficacy of targeted diagnostic testing strategies are uncertain. The aim of this study was to systematically review interventions designed to reduce pathology and chest radiograph testing in patients admitted to the intensive care unit (ICU). A predetermined protocol and search strategy included OVID MEDLINE, OVID EMBASE and the Cochrane Central Register of Controlled Trials from inception until 20 November 2019. Eligible publications included interventional studies of patients admitted to an ICU. There were no language restrictions. The primary outcomes were in-hospital mortality and test reduction. Key secondary outcomes included ICU mortality, length of stay, costs and adverse events. This systematic review analysed 26 studies (with more than 44,00 patients) reporting an intervention to reduce one or more diagnostic tests. No studies were at low risk of bias. In-hospital mortality, reported in seven studies, was not significantly different in the post-implementation group (829 of 9815 patients, 8.4%) compared with the pre-intervention group (1007 of 9848 patients, 10.2%), (relative risk 0.89, 95% confidence intervals 0.79 to 1.01, P = 0.06, I2 39%). Of the 18 studies reporting a difference in testing rates, all reported a decrease associated with targeted testing (range 6%–72%), with 14 (82%) studies reporting >20% reduction in one or more tests. Studies of ICU targeted test interventions are generally of low quality. The majority report substantial decreases in testing without evidence of a significant difference in hospital mortality.

Abstract Background The shoulder joint is the most commonly injured joint in CrossFit practitioners, because of the high intensity and loads associated with this sport. Despite the large number of clinical cases, there is a shortage of studies that investigate influence of biomechanical aspects of upper limbs' injuries on CrossFit practitioners. This study hypothesized that there would be a difference in function, strength, and muscle activation between Crossfit practitioners with and without shoulder pain. Methods We divided 79 Crossfit practitioners into two groups according to whether they reported pain (n = 29) or no pain (n = 50) in the shoulder during Crossfit training. Muscle function, strength, and activation were assessed using the Disability Arm, Shoulder and Hand function questionnaire, Upper Quarter Y Balance Test and Closed Kinetic Chain Upper Extremity Stability Test shoulder tests, isometric muscle strength assessment by manual dynamometry and muscle activation by surface electromyography and pain report. Results The function based on questionnaire was associated with pain (p = 0.004). We observed a statistically significant difference between the two groups only in the surface electromyography activity of the lower trapezius, and in the variables of shoulder pain and function (p = 0.038). Conclusion Crossfit practitioners with shoulder pain occurring during training showed good function and stability of the shoulder joint, but there was a reduction in the activation of stabilizing muscles, especially the lower trapezius.

Background: Azithromycin (AZM) has been widely used in the management of Covid-19. However, the evidence on its actual effects remains disperse and difficult to apply in clinical settings. This systematic review and metanalysis summarizes the studies on the beneficial and adverse effect of AZM in patients with Covid-19. Methods: The PRISMA 2020 statement criteria were followed. Randomized controlled trials (RCTs) and observational studies comparing clinical outcomes of patients treated, and not treated, with AZM, indexed until the 5th of July 2021, were searched in PubMed, Embase, The Web of Science, Scopus, The Cochrane Central Register of Controlled Trials, and MedRXivs. We used Random-effects models to estimate pooled effect size from aggregate data. Results: The initial search produced 4950 results. Finally, 16 studies, five RCTs and 11 with an observational design, with a total of 22984 patients, were included. The metanalysis showed no difference in mortality for those treated, or not, with AZM, OR: 0.95 (0.79-1.13). There was also no significant difference for those treated, and not, with AZM in need for hospital admission or time to admission from ambulatory settings, clinical severity, need for intensive care, or adverse effects. Conclusions: These results presented in this review do not support the use of AZM in the management of Covid-19. They also show that any harm caused to the patient who received it is unlikely. Future research on treatment for patients with Covid-19 may need to focus on other drugs

Early Use

Abstract Objectives While anti-tumor necrosis factor alpha (anti-TNFa) therapies for Crohn disease (CD) were initially introduced in 1998 for biologic therapies are often introduced after a minimum of 6 years after diagnosis. The benefit of anti-TNFa early in the course of CD is still controversial, with some studies showing better outcomes but others not. To determine whether earlier introduction of anti-TNFa therapy improves efficacy in clinical trials or clinical series, we aimed to perform a meta-analysis comparing early vs late anti-TNFa use in the management of CD. Methods A comprehensive search of MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and Scopus was conducted from each database’s inception to November 3, 2019. We included comparative studies of early vs late use of anti-TNFa therapy in adult patients with CD. Results Eleven studies were included in the analysis, with a total of 2501 patients. Meta-analysis demonstrated that the early use of anti-TNFa was associated with a statistically significant decrease in the need for surgery (relative risk [RR] = 0.43; 95% confidence interval [CI], 0.26–0.69; I2 = 68%) and disease progression (RR = 0.51; 95% CI, 0.35–0.75; I2 = 61%). Early use also showed an increase in early remission (RR = 1.94; 95% CI, 1.54–2.46; I2 = 0%) and clinical response. There was no statistically significant difference in achieving late remission (RR = 1.39; 95% CI, 0.94–2.05; I2 = 65%) or mucosal healing (RR = 1.10; 95% CI, 0.63–1.91; I2 = 0%). Conclusion This systematic review suggests that using anti-TNFa earlier in the treatment of CD (within 3 years) may improve clinical outcomes compared to late administration in terms of achieving early clinical remission, clinical response, disease progression, and the need for surgery.

AbstractAlthough prophylaxis for venous thromboembolism (VTE) is recommended after many surgeries, evidence base for use of VTE prophylaxis after foot or ankle surgery has been elusive, leading into varying guidelines recommendations and notable practice variations. We conducted a systematic review of the literature to determine if use of VTE prophylaxis decreased the frequency of subsequent VTE, including deep vein thrombosis (DVT) or pulmonary embolism (PE), compared with control. We searched PubMed, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov through May 2018, for randomized controlled trials (RCTs) or prospective controlled observational studies of VTE prophylaxis in patients undergoing foot and ankle surgery. Our search retrieved 263 studies, of which 6 were finally included comprising 1,600 patients. Patients receiving VTE prophylaxis had lower risk for subsequent DVT (risk ratio [RR]: 0.72; 95% confidence interval [CI]: 0.55–0.94) and subsequent VTE (RR: 0.72; 95% CI: 0.55–0.94). There was only one case of nonfatal PE, no cases of fatal PE, and no change in all-cause mortality (RR: 3.51; 95% CI: 0.14–84.84). There was no significant difference in the risk for bleeding (RR: 2.12; 95% CI: 0.53–8.56). Very few RCTs exist regarding the efficacy and safety of VTE prophylaxis in foot and ankle surgery. Prophylaxis appears to reduce the risk of subsequent VTE, but the event rates are low and symptomatic events are rare. Future studies should determine the subgroups of patients undergoing foot or ankle surgery in whom prophylaxis may be most useful.

Abstract Repetitive transcranial magnetic stimulation (rTMS) is a safe and effective treatment for major depression (MD). However, the perceived lack of a suitable sham rTMS condition might have compromised the success of blinding procedures in clinical trials. Thus, we conducted a systematic review and meta-analysis of randomized, double-blind and sham-controlled trials (RCTs) on high frequency (HF-), low frequency (LF-) and bilateral rTMS for MD. We searched the literature from January 1995 to July 2012 using Medline, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials and Scopus. The main outcome measure was participants' ability to correctly guess their treatment allocation at study end. We used a random-effects model and risk difference (RD). Overall, data were obtained from seven and two RCTs on HF- and bilateral rTMS, respectively. No RCT on LF-rTMS reporting on blinding success was found. HF- and bilateral rTMS trials enrolled 396 and 93 depressed subjects and offered an average of approximately 13 sessions. At study end, 52 and 59% of subjects receiving HF-rTMS and sham rTMS were able to correctly guess their treatment allocation, a non-significant difference (RD = −0.04; z = −0.51; p = 0.61). Furthermore, 63.3 and 57.5% of subjects receiving bilateral and sham rTMS were able to correctly guess their treatment allocation, also a non-significant difference (RD = 0.05; z = 0.49; p = 0.62). In addition, the use of angulation and sham coil in HF-rTMS trials produced similar results. In summary, existing sham rTMS interventions appear to result in acceptable levels of blinding regarding treatment allocation.

An increasing number of studies have focused on whether peritoneal dialysis (PD) can be used for the urgent initiation of dialysis in patients with chronic kidney disease (CKD). We performed this systematic review and meta-analysis to evaluate the feasibility and safety of urgent-start PD compared with those of planned PD and urgent-start hemodialysis (HD) in this population. PubMed, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), clinicaltrials.gov , and China National Knowledge Infrastructure (CNKI) were searched for relevant studies. Conference abstracts were also searched in relevant websites. The meta-analysis was performed using RevMan 5.3 software. A total of 15 trials involving 2426 participants were identified. The quality of the included studies was fair, but the quality of evidence was very low. Unadjusted meta-analysis showed that urgent-start PD had significantly higher mortality than planned PD, while adjusted meta-analysis did not show a significant difference. Higher incident of leakage and catheter mechanical dysfunction were observed in urgent-start PD. However, peritonitis, exit-site infection, or PD technique survival were comparable between urgent-start and planned PD. The all-cause mortality was comparable in urgent-start PD and urgent-start HD. Bacteremia was significantly lower in the urgent-start PD group than with urgent-start HD. Based on limited evidences, PD may be a viable alternative to HD for CKD patients requiring urgent-start dialysis. Because of the inconsistent results and the low quality of evidence, a definitive conclusion could not be drawn for whether urgent-start PD was comparable with planned PD. Therefore, high-quality and large-scale studies are needed in the future.

Risk of bias and quality of included studies were assessed. Data of included studies were extracted, and meta-analysis was conducted where appropriate.Results12 397 unique studies were identified, of which 20 were included and 16 were eligible for meta-analysis. Reviewed studies clearly described the aim/hypothesis and main outcome measure, but most lacked sample size calculation and assessor blinding. Meta-analyses showed individuals with CAI had lower eccentric and concentric evertor strength (30 and 120°/s; Nm; standardised mean difference (SMD) between −0.73 and −0.95), eccentric invertor strength (60 and 120°/s; both Nm and Nm/kg; SMD between −0.61 and −1.37), concentric invertor strength (60 and 120°/s; Nm; SMD=−0.7) and concentric knee extensor strength (SMD=−0.64) compared with control participants. Ankle eccentric dorsiflexor strength was not different between groups. Although pooling was not possible, data from three separate studies indicated that hip flexor, abductor and external rotator strength, but not hip adductor and extensor strength, was lower in individuals with CAI than in control participants.ConclusionIndividuals with CAI have ankle inversion and eversion strength deficits. Our data also point to differences between individuals with CAI and controls in hip and knee strength. These elements of the kinetic chain should be evaluated by clinicians who rehabilitate individuals with CAI.PROSPERO registration numberCRD42016037759.

Abstract Background Research recommends the development and evaluation of interventions to support women with breast cancer in returning to, or managing, work. Despite this, there has historically been a paucity of rehabilitation interventions to support women with breast cancer to maintain or return to their work role. The aim of this systematic review was to examine key characteristics of rehabilitation interventions, and their effectiveness on work outcomes for women with breast cancer, compared to usual care. Methods A systematic review was conducted of controlled studies of rehabilitation interventions with work outcomes for women with breast cancer. Six databases were systematically searched: EMBASE, Web of Science, MEDLINE (OVID), CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials (CENTRAL). Results are presented either as pooled odds ratio (OR) or pooled effect size (hedges g) between groups, with 95% confidence intervals (CI). Narrative synthesis was conducted on intervention outcomes not suitable for meta-analysis. Results Five thousand, five hundred and thirty-five studies were identified. Nine out of 28 abstracts met inclusion criteria. Heterogeneity of interventions and outcomes precluded meta-analysis for most outcomes. Of the interventions included in meta-analysis, no significant differences compared to usual care were found for sick leave (2 studies (12 months); OR 1.11 (95% CI: 0.66 to 1.87), number of sick days taken (2 studies (six months); difference in effect: -0.08, (95% CI: -0.48 to 0.38) or working hours (2 studies (12 months); 0.19, (95% CI: -0.20 to 0.64). Only one study, with a multidisciplinary intervention, showed a significant difference for work outcomes when compared to usual care. Work-specific content featured in three interventions only, none of which provided conclusive evidence for improvement in work outcomes. Enhanced physical and psychological sequalae, and quality of life was observed in some studies. Conclusion There remains a lack of effective and methodologically rigorous rehabilitation intervention studies for breast cancer survivors. The development and evaluation of effective rehabilitation interventions to support return to work is warranted.
