Review
Martín-Rodríguez, S, Loturco, I, Hunter, AM, Rodríguez-Ruiz, D, and Munguia-Izquierdo, D. Reliability and measurement error of tensiomyography to assess mechanical muscle function: A systematic review. J Strength Cond Res 31(12): 3524-3536, 2017-Interest in studying mechanical skeletal muscle function through tensiomyography (TMG) has increased in recent years. This systematic review aimed to (a) report the reliability and measurement error of all TMG parameters (i.e., maximum radial displacement of the muscle belly [Dm], contraction time [Tc], delay time [Td], half-relaxation time [½ Tr], and sustained contraction time [Ts]) and (b) to provide critical reflection on how to perform accurate and appropriate measurements for informing clinicians, exercise professionals, and researchers. A comprehensive literature search was performed of the Pubmed, Scopus, Science Direct, and Cochrane databases up to July 2017. Eight studies were included in this systematic review. Meta-analysis could not be performed because of the low quality of the evidence of some studies evaluated. Overall, the review of the 9 studies involving 158 participants revealed high relative reliability (intraclass correlation coefficient [ICC]) for Dm (0.91-0.99); moderate-to-high ICC for Ts (0.80-0.96), Tc (0.70-0.98), and ½ Tr (0.77-0.93); and low-to-high ICC for Td (0.60-0.98), independently of the evaluated muscles. In addition, absolute reliability (coefficient of variation [CV]) was low for all TMG parameters except for ½ Tr (CV = >20%), whereas measurement error indexes were high for this parameter. In conclusion, this study indicates that 3 of the TMG parameters (Dm, Td, and Tc) are highly reliable, whereas ½ Tr demonstrate insufficient reliability, and thus should not be used in future studies.

Meta-Analysis
BACKGROUND
Patients with COVID-19 will experience high levels of anxiety and depression and poor levels of sleep and quality of life (QoL) due to isolation treatment and uncertain outcomes. Progressive muscle relaxation (PMR) exercises show promising treatment effects on mental health and sleep problems and overall QoL in COVID-19 patients. This study aimed to evaluate the efficacy and safety of PMR exercises in patients with COVID-19.
METHODS
Both experimental and non-experimental studies related to PMR and COVID-19 were systematically searched in the PubMed, Cochrane Library, PEDro and HINARI databases for studies published from the occurrence of the pandemic to December 2022. Study selection, methodological quality assessment and data extraction were carried out by 2 independent authors. Efficacy outcomes were evaluated for sleep quality, anxiety, depression, and QoL. The safety outcomes were evaluated based on adverse events reported. Review manager (RevMan 5.4, Cochrane collaboration) was used for the data analysis.
RESULTS
Four studies with 227 subjects were included in this systematic review. The pooled results indicated that PMR interventions improved the sleep quality score standardized mean difference (SMD): -0.23; 95% confidence interval (CI): -0.54, 0.07; P = .13, level of anxiety SMD: -1.35; 95% CI -2.38, -0.32; P = .01 compared to the usual care. Depression level, disease severity and QoL were also improved following PMR interventions. Only 1 study reported worsening of 1 patient clinical status while all other studies did not report any adverse events during the interventions.
CONCLUSIONS
PMR interventions can improve the sleep quality, anxiety, depression, disease severity and QoL in patients with mild to moderate COVID-19 in a short-term period compared to the usual care. However, there was indecision about the safety and long-term effects of PMR.

Review
Understanding passive skeletal muscle mechanics is critical in defining structure-function relationships in skeletal muscle and ultimately understanding pathologically impaired muscle. In this systematic review, we performed an exhaustive literature search using PRISMA guidelines to quantify passive muscle mechanical properties, summarized the methods used to create these data, and make recommendations to standardize future studies. We screened over 7500 papers and found 80 papers that met the inclusion criteria. These papers reported passive muscle mechanics from single muscle fiber to whole muscle across 16 species and 54 distinct muscles. We found a wide range of methodological differences in sample selection, preparation, testing, and analysis. The systematic review revealed that passive muscle mechanics is species and scale dependent-specifically within mammals, the passive mechanics increases non-linearly with scale. However, a detailed understanding of passive mechanics is still unclear because the varied methodologies impede comparisons across studies, scales, species, and muscles. Therefore, we recommend the following: smaller scales may be maintained within storage solution prior to testing, when samples are tested statically use 2-3 min of relaxation time, stress normalization at the whole muscle level be to physiologic cross-sectional area, strain normalization be to sarcomere length when possible, and an exponential equation be used to fit the data. Additional studies using these recommendations will allow exploration of the multiscale relationship of passive force within and across species to provide the fundamental knowledge needed to improve our understanding of passive muscle mechanics.

Review
BACKGROUND
Palliative care patients desire more symptom management interventions that are complementary to their medical treatment. Within the multi-professional team, nurses could help support pain management with non-pharmacological interventions feasible for their practice and adaptable to palliative care patients' needs.
OBJECTIVES
The objective was to identify non-pharmacological interventions feasible in the nursing scope of practice affecting pain in palliative care patients.
DESIGN
A systematic review.
DATA SOURCES AND METHODS
A defined search strategy was used in PubMed, CINAHL, PsycINFO, and Embase. Search results were screened double-blinded. Methodological quality was double-appraised with the Joanna Briggs Institute Critical Appraisal Tools. Data were extracted from selected studies and the findings were summarized. The methodological quality, quantity of studies evaluating the same intervention, and consistency in the findings were synthesized in a best-evidence synthesis to rank evidence as strong, moderate, limited, mixed, or insufficient.
RESULTS
Out of 2385 articles, 22 studies highlighted non-pharmacological interventions in the nursing scope of practice. Interventions using massage therapy and virtual reality demonstrated most evidentiary support for pain management, while art therapy lacked sufficient evidence. Mindful breathing intervention showed no significant reduction in pain. Hypnosis, progressive muscle-relaxation-interactive-guided imagery, cognitive-behavioral audiotapes, wrapped warm footbath, reflexology, and music therapy exhibited promising results in pain reduction, whereas mindfulness-based stress reduction program, aromatherapy, and aroma-massage therapy did not.
CONCLUSION
Despite not all studies reaching significant changes in pain scores, non-pharmacological interventions can be clinically relevant to palliative care patients. Its use should be discussed for its potential value and nurses to be trained for safe practice. Methodologically rigorous research for non-pharmacological interventions in nursing scope of practice for pain relief in palliative care patients is necessary.

Review
Electrical stimulation through surface electrodes is a non-invasive therapeutic technique used to improve voluntary motor control and reduce pain and spasticity in patients with central nervous system injuries. The Exopulse Mollii Suit (EMS) is a non-invasive full-body suit with integrated electrodes designed for self-administered electrical stimulation to reduce spasticity and promote flexibility. The EMS has been evaluated in several clinical trials with positive findings, indicating its potential in rehabilitation. This review investigates the effectiveness of the EMS for rehabilitation and its acceptability by patients. The literature was collected through several databases following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Positive effects of the garment on improving motor functions and reducing spasticity have been shown to be related to the duration of the administration period and to the dosage of the treatment, which, in turn, depend on the individual's condition and the treatment goals. Moreover, patients reported wellbeing during stimulation and a muscle-relaxing effect on the affected limb. Although additional research is required to determine the efficacy of this device, the reviewed literature highlights the EMS potential to improve the motor capabilities of neurological patients in clinical practice.

Meta-Analysis
Velocity-based training is an advanced auto-regulation method that uses objective indices to dynamically regulate training loads. However, it is unclear currently how to maximize muscle strength with appropriate velocity-based training settings. To fill this gap, we conducted a series of dose-response and subgroup meta-analyses to check the effects of training variables/parameters, such as intensity, velocity loss, set, inter-set rest intervals, frequency, period, and program, on muscle strength in velocity-based training. A systematic literature search was performed to identify studies via PubMed, Web of Science, Embase, EBSCO, and Cochrane. One repetition maximum was selected as the outcome to indicate muscle strength. Eventually, twenty-seven studies with 693 trained individuals were included in the analysis. We found that the velocity loss of 15 to 30%, the intensity of 70 to 80%1RM, the set of 3 to 5 per session, the inter-set rest interval of 2 to 4 min, and the period of 7 to 12 weeks could be appropriate settings for developing muscle strength. Three periodical programming models in velocity-based training, including linear programming, undulating programming, and constant programming, were effective for developing muscle strength. Besides, changing periodical programming models around every 9 weeks may help to avoid a training plateau in strength adaption.

Future Science OA Dec 2023This meta-analysis was performed to assess the efficacy and safety of mavacamten in patients with hypertrophic cardiomyopathy.
AIM
This meta-analysis was performed to assess the efficacy and safety of mavacamten in patients with hypertrophic cardiomyopathy.
METHODS & MATERIALS
A search was conducted using PubMed, Cochrane, and Scopus up to August 2022 for randomized studies reporting our pre-specified outcomes.
RESULTS
It was observed that mavacamten significantly improved New York Heart Association class (p < 0.009), Clinical Summary Score of the Kansas City Cardiomyopathy Questionnaire (p = 0.02), post-exercise left ventricular outflow tract gradient (p < 0.00001), functional end point (p = 0.05), and lowered septal reduction therapy rates (p < 0.00001). However, there were no significant differences in the ≥1 severe adverse events, ≥1 treatment-emergent adverse events, left ventricular volume index, left ventricular filling pressure, left ventricular end-diastolic volume index, and peak oxygen uptake (pVO).
CONCLUSION
Future large-scale trials are required to confirm our results and determine the long-term benefits and risks of mavacamten use in these patients.

The efficacy and safety of muscle relaxants in inflammatory arthritis: a Cochrane systematic review.The Journal of Rheumatology. Supplement Sep 2012To determine the efficacy and safety of muscle relaxants in pain management in patients with inflammatory arthritis (IA). (Review)
Review
OBJECTIVE
To determine the efficacy and safety of muscle relaxants in pain management in patients with inflammatory arthritis (IA).
METHODS
We searched the Cochrane Central Register of Controlled Trials, Medline, Embase, and PsychINFO for randomized controlled trials in adults with IA that compared any muscle relaxant (administered via any route) to another analgesic intervention or placebo. We also searched the 2008-2009 American College of Rheumatology and European League Against Rheumatism abstracts and performed a hand search of reference lists of relevant articles. Primary outcomes were patient-reported pain relief ≥ 30% and withdrawals due to adverse events. Two authors independently assessed methodological quality and extracted data.
RESULTS
Six trials (126 participants) were included in this review. All trials were deemed to have a high risk of bias. Five crossover trials evaluated benzodiazepine; 4 assessed diazepam (n = 71), and one assessed triazolam (n = 15). The sixth trial, a parallel-group study, evaluated zopiclone (non-benzodiazepine, n = 40). No trial was longer than 2 weeks and 3 single-dose trials assessed outcomes at 24 hours only. Overall, the included trials failed to find evidence of a beneficial effect of muscle relaxants over placebo (at 24 hours, 1 week, or 2 weeks) or in addition to nonsteroidal antiiflammatory drugs (at 24 hours) on pain intensity, function, or quality of life. Data from 2 trials of longer than 24-hour duration (diazepam and zopiclone, n = 74) found that participants who received a muscle relaxant had significantly more adverse events compared with those who received placebo [number needed to harm (NNTH) 3, 95% CI 2 to 7]. These were predominantly central nervous system side effects including dizziness and drowsiness (NNTH 3, 95% CI 2 to 11).
CONCLUSION
Based upon the currently available evidence in patients with IA, benzodiazepines (diazepam and triazolam) do not appear to be beneficial in improving pain over 24 hours or 1 week. The non-benzodiazepine agent zopiclone also did not significantly reduce pain over 2 weeks. However, even short-term muscle relaxant use (24 hours to 2 weeks) is associated with significant adverse events, predominantly drowsiness and dizziness.

Review
The aim of this study was to systematically review the existing scientific literature and evidence about (a) the validation of masseter muscle ultrasonography for accurate assessment of muscle thickness and (b) the reproducibility of masseter muscle thickness measures. An electronic literature search was conducted using determined keywords on specific databases. Preliminary search revealed 298 articles listed in Medline, Scopus and Web of Science. 60 duplicates were rejected, leaving 238 articles for review. After reading titles and abstracts, 31 articles remained. 23 articles were assessed for eligibility. These articles were categorized as follows: thickness, cross-section, volume and the length of the masseter muscle measured by ultrasonography. It is possible to verify the thickness of the masseter muscle in males and females in relaxation (10-15 and 9-13 mm, respectively) and contraction (14-19 and 12-15 mm, respectively). A similar tendency can also be evidenced in other measurements. Many studies evaluate masseter muscle dimensions to relate it to cephalometric analysis as such to evaluate morphological variations. It can be concluded that ultrasound is a reliable clinical tool for masseter muscle measurements, yet there is a need for standardization of methods and parameters to be recorded.

A systematic review and meta-analysis of the effects of muscle relaxation training conventional nursing on the depression, anxiety and life quality of patients with breast cancer.
BACKGROUND
Muscle relaxation training is a method of gradually relaxing the whole body by consciously controlling the process of muscle contraction and relaxation, which is mostly used to improve the physical and mental health of breast cancer patients and improve the quality of life of patients. We conducted a systematic review to compare the effects of muscle relaxation training and conventional nursing on the psychological health and quality of life (QoL) of breast cancer patients. The results of this study provide a basis for nursing program selection of breast cancer patients.
METHODS
The PubMed, EMbase, Web of Science, The Cochrane Library, China national knowledge infrastructure (CNKI), WanFang Data, (China Biology Medicine disc) CBM, and WWW.CQVIP.COM (VIP) databases were searched to retrieve articles on randomized controlled trials (RCTs) or quasi-RCTs on the effects of muscle relaxation training on the mental health and QoL of breast cancer patients. The search period ran from the establishment of the databases to August 31st, 2021. Two researchers independently screened the literature, extracted the data, and The Cochrane Handbook for Systematic Reviews of Interventions assessed the risk of bias in the included studies. Stata 15.0 software was then used for the meta-analysis.
RESULTS
Funnel plots were analyzed by E Egger's test and Begg's test. The results of the test (P>0.05) showed that the possibility of publication bias was small. A total of 13 RCTs and quasi-RCTs, comprising 1,355 patients, were included in the meta-analysis. The results for the outcome measures were as follows: level of depression [weighted mean difference (WMD) =-9.31, 95% confidence interval (CI): -11.96 to -6.65, level of anxiety (WMD =-8.96, 95% CI: -10.06 to -7.86)], and QoL (WMD =13.13, 95% CI: 7.24, 19.02). The results showed that muscle relaxation training can significantly reduce depression and anxiety in breast cancer patients, improve their quality of life, and can be used as the first choice for breast cancer patients to improve negative emotions.
DISCUSSION
Muscle relaxation training significantly reduced the depression and anxiety of breast cancer patients, improved their QoL, and brought about both psychological and QoL improvements.
