Összefoglaló. Bevezetés: A megváltozott statikus és/vagy dinamikus lapockapozíciót, azaz a scapuladyskinesist gyakran vonják párhuzamba a vállelváltozásokkal. Mindemellett a lapocka kinematikai eltérései nagy számban jelen lehetnek tünetmentes egyéneknél is, melegágyat biztosítva a későbbi vállelváltozások kialakulásának. Célkitűzés: Munkánk fő célja az volt, hogy felhívja a figyelmet ezen problémakör fontosságára, valamint hogy megvizsgálja a scapuladyskinesis előfordulásának gyakoriságát és körülményeit az átlagpopulációban. Módszer: Mintánk 70 főből állt (átlagéletkor: 22,17 ± 1,77 év). 67%-uk férfi, míg 33%-uk nő volt. A scapuladyskinesis fennállását McClure-féle ’Scapular Dyskinesis Test’-tel vizsgáltuk. A résztvevők vállfájdalmának intenzitását vizuális analóg skála segítségével, habituális testtartásukat fotogrammetriás módszerrel, főbb lapockastabilizáló izmaik izomerejét pedig Kendall-féle manuális izomerőtesztekkel mértük fel. Mindemellett felvettük antropometriai adataikat, valamint megkérdeztük, hogy milyen gyakran végeznek sporttevékenységet. Eredmények: A résztvevők 53%-ánál találtunk valamilyen fokú scapuladyskinesist. A habituális testtartást vizsgáló fotogrammetriás felmérés eredményei és a scapuladyskinesist mérő McClure-féle teszt eredményei között szignifikáns összefüggést találtunk (p = 0,01). A sportolási gyakoriság és a scapuladyskinesis előfordulása között jelentős összefüggést tapasztaltunk (p = 0,01). A fájdalom erőssége és a scapuladyskinesis előfordulása között szignifikáns volt az összefüggés (p = 0,03). A scapuladyskinesist mérő McClure-féle teszt és az azonos oldali felső végtagon izomerő-csökkenést mutató tesztek eredményei között szintén szignifikáns összefüggést tapasztaltunk (p = 0,01). Következtetés: Az elit sportolók mellett az átlagos populációban is jelentős mértékben jelen lehetnek a lapocka kinematikai eltérései. Mindez jelentős összefüggésben állhat az adott személy életmódjával és egészségmagatartásával, valamint kiemelt szerepet játszhat a krónikus vállfájdalom kialakulásában.

However, shoulder kinematic abnormalities may also be present in large numbers in asymptomatic individuals. Objective: The main goal of our work was to draw attention to the importance of scapular dyskinesis in shoulder pathologies. Method: The final sample consisted of 70 people (average age: 22.17 ± 1.77 years), 67% of them was male and 33% female. The presence of scapular dyskinesis was assessed by McClure’s Scapular Dyskinesis Test. Visual analog scale was used to examine the shoulder pain of the participants, photogrammetric method was used to document their habitual posture. Kendall’s manual muscle testing methods were used to determine the muscle strength of the individual muscles of the shoulder girdle; we also recorded their anthropometric data and asked them about their sporting habits. Results: In 53% of the participants, some degree of scapular dyskinesis was found. We observed significant correlation between the sporting habits and scapular dyskinesis (p = 0.01). Significant correlation was observed between the posture and scapular dyskinesis (p = 0.01). Between the strength of pain and the dyskinesis, we found a significant correlation (p = 0.03). There was a significant correlation between the results of the McClure’s test and the tests showing muscle strength loss around the scapula (p = 0.01). Conclusion: In addition to elite athletes, scapular dyskinesis may also be significantly present in the average population and can play a key role in the development of shoulder pain.

Background: Osteoarthritis is a disease of the joints that can cause disability and is progressive in the joints which cause changes in the water content, proteoglycin content, and collagen in the joints. One of the ways to improve functional ability in osteoarthritis cases is to use isotonic and isometric training exercise. Pain is a clinical symptom of knee osteoarthritis, limiting movement due to pain over time will cause rehabilitation problems such as impaired flexibility and stability, reduction of muscle mass (atrophy). Mild and moderate intensity quadriceps strength training is effective at achieving optimal muscle strength and function without causing significant muscle damage. Destination: The purpose of this study was to analyze the effect of isotonic and isometric exercises on muscle strength. Research methods: This study uses a pre-experimental research type using "One Group Pre - test and Post - Test". This research has carried out the first observation (pretest) so that researchers can test the changes that occur after the treatment, and the control group. Result: with the Wilcoxon signed rank test test the isometric and isotonic groups had p = 0.000 while the control group had a significance value of p = 1,000; and the 3 groups test has different values, namely: isotonic exercise has a value of 27.67; isometric; 28.60; and control 12.73. The conclusion that can be concluded that the value of isometric training has the highest value, namely 28.60 which means it is the most effective exercise to increase the value of Manual Muscle Testing. Conclusion: There is an effect of giving isometric and isotonic exercises in strengthening the quadriceps muscles.

Abstract Objectives Muscle weakness in idiopathic inflammatory myopathies (IIMs) is conventionally assessed using manual muscle testing (MMT). However, more objective tools must be developed to accurately and reliably quantify muscle strength in myositis patients. Hand-held dynamometry (HHD) is a quantitative, portable device with reported reliability in neuromuscular disorders. Our aim was to assess the reliability, validity and responsiveness of HHD in myositis. Methods Myositis patients [DM, necrotizing myopathy (NM), PM and anti-synthetase syndrome] evaluated at the University of Pittsburgh myositis centre were prospectively enrolled. Each patient was assessed at 0, 3 and 6 months for validated outcome measures of myositis disease activity and physical function. At each visit, muscle strength was assessed using both MMT and HHD (Micro FET2, Hoggan Health Industries, Draper, UT, USA). The reliability, validity and responsiveness of the HHD was assessed using standard statistical methods. Results Fifty IIM patients (60% female; mean age 51.6 years; 6 PM, 9 NM, 24 DM and 11 anti-synthetase syndrome) were enrolled. HHD showed strong test–retest intrarater reliability (r = 0.96) and interrater reliability (r = 0.98). HHD correlated significantly with the MMT score (r = 0.48, P = 0.0006) and myositis disease activity and functional measures. Longitudinal analysis showed a significant and strong association between the HHD and MMT as well as 2016 ACR/EULAR myositis response criteria (r = 0.8, P < 0.0001) demonstrating responsiveness. The mean effect size and standardized response mean of HHD was large: 0.95 and 1.03, respectively. MMT had a high ceiling effect compared with HHD. Conclusion HHD demonstrated strong reliability, construct validity and responsiveness in myositis patients. External validation studies are required to confirm these findings.

ObjectiveTo determine the effects of 10 years of enzyme replacement therapy (ERT) in adult patients with Pompe disease, focusing on individual variability in treatment response.MethodsIn this prospective, multicenter cohort study, we studied 30 patients from the Netherlands and France who had started ERT during the only randomized placebo-controlled clinical trial with ERT in late-onset Pompe disease (NCT00158600) or its extension (NCT00455195) in 2005 to 2008. Main outcomes were walking ability (6-minute walk test [6MWT]), muscle strength (manual muscle testing using Medical Research Council [MRC] grading), and pulmonary function (forced vital capacity [FVC] in the upright and supine positions), assessed at 3- to 6-month intervals before and after the start of ERT. Data were analyzed with linear mixed-effects models for repeated measurements.ResultsMedian follow-up duration on ERT was 9.8 years (interquartile range [IQR] 8.3–10.2 years). At the group level, baseline 6MWT was 49% of predicted (IQR 41%–60%) and had deteriorated by 22.2 percentage points (pp) at the 10-year treatment point (p < 0.001). Baseline FVC upright was 54% of predicted (IQR 47%–68%) and decreased by 11 pp over 10 years (p < 0.001). Effects of ERT on MRC sum score and FVC supine were similar. At the individual level, 93% of patients had initial benefit of ERT. Depending on the outcome measured, 35% to 63% of patients had a secondary decline after ≈3 to 5 years. Still, at 10 years of ERT, 52% had equal or better 6MWT and/or FVC upright compared to baseline.ConclusionsThe majority of patients with Pompe disease benefit from long-term ERT, but many patients experience some secondary decline after ≈3 to 5 years. Individual variation, however, is considerable.Classification of evidenceThis study provides Class IV evidence that for the majority of adults with Pompe disease, long-term ERT positively affects, or slows deterioration in, muscle strength, walking ability, and/or pulmonary function.

Lower and upper limb maximum muscular force development is an important indicator of physical capacity. Manual muscle testing, load cell coupled with a signal conditioner, and handheld dynamometry are three widely used techniques for measuring isometric muscle strength. Recently, there is a proliferation of low-cost tools that have potential to be used to measure muscle strength. This study examined both the criterion validity, inter-day reliability and intra-day reliability of a microcontroller-based load cell amplifier for quantifying muscle strength. To do so, a low-cost microcontroller-based load cell amplifier for measuring lower and upper limb maximal voluntary isometric muscular force was compared to a commercial grade signal conditioner and to a handheld dynamometer. The results showed that the microcontroller-based load cell amplifier correlated nearly perfectly (Pearson's R-values between 0.947 to 0.992) with the commercial signal conditioner and the handheld dynamometer, and showed good to excellent association when calculating ICC scores, with values of 0.9582 [95% C.I.: 0.9297–0.9752] for inter-day reliability and of 0.9269 [95% C.I.: 0.8909–0.9533] for session one, intra-day reliability. Such results may have implications for how the evaluation of muscle strength measurement is conducted in the future, particularly for offering a commercial-like grade quality, low cost, portable and flexible option.

Background: Biallelic variants in Anoctamin 5 (ANO5) gene are causative of limb-girdle muscular dystrophy (LGMD) R12 anoctamin5-related, non-dysferlin Miyoshi-like distal myopathy (MMD3), and asymptomatic hyperCKemia. Objective: To describe clinic, histologic, genetic and imaging features, of ANO5 mutated patients. Methods: Five patients, four from France (P1, P2, P3 and P4) and one from Mexico (P5), from four families were included. P1 and P2, belonging to group 1, had normal muscle strength; Group 2, P3, P4 and P5, presented with muscular weakness. Muscle strength was measured by manual muscle testing, Medical Research Council (MRC) grades 1/5 to 5/5. Laboratory exams included serum CK levels, nerve conduction studies (NCS)/needle electromyography (EMG), pulmonary function tests, EKG and cardiac ultrasound. ANO5 molecular screening was performed with different approaches. Results: Group 1 patients showed myalgias with hyperCKemia or isolated hyperCKemia. Group 2 patients presented with limb-girdle or proximo-distal muscular weakness. Serum CK levels ranged from 897 to 5000 UI/L. Muscle biopsy analysis in P4 and P5 showed subsarcolemmal mitochondrial aggregates. Electron microscopy confirmed mitochondrial proliferation and revealed discontinuity of the sarcolemmal membrane. Muscle MRI showed asymmetrical fibro-fatty substitution predominant in the lower limbs. P1 and P2 were compound heterozygous for c.191dupA (p.Asn64Lysfs*15) and c.1898 + G>A; P3 was homozygous for the c.692G>T. (p.Gly231Val); P4 harbored a novel biallelic homozygous exons 1–7 ANO5 gene deletion, and P5 was homozygous for a c.172 C > T (p.(Arg 58 Trp)) ANO5 pathogenic variant. Conclusions: Our cohort confirms the wide clinical variability and enlarge the genetic spectrum of ANO5-related myopathies.

Body postures can project nonverbally how a human being feels. Postural changes affect thoughts, emotions, and energy levels, and conversely, energy levels, emotions, and thoughts affect posture. The purpose of this study was to explore how changes in erect or standing body posture affect positive energy levels, emotions, and thoughts. For example, increases in perceived arm muscle strength as well as recall of positive emotional memories due to posture changes will positively affect client beliefs about coping with difficult life circumstances. In this study, 33 participants paired up as “testers” or “subjects” and took turns standing either in an erect or collapsed/slouched posture. All subjects proceeded through a manual muscle testing procedure by raising their arms and attempting to resist the steady downward pressure applied by the tester to their forearm near their wrists. All but one (98%) of the subjects perceived greater arm strength as they resisted the downward pressure when they stood in an erect posture compared with when they stood in a collapsed/slouched posture. Similarly, testers observed that the subject were much stronger in their ability to resist the downward pressure in the erect versus slouched position (p &lt; .01). The somatic feedback of muscle strength and the guided practice of how body position may affect recall of memories can be used to demonstrate the mind/emotion and body interactions. This study points out that psychology and bioneurofeedback training needs to understand how important body posture, movement, and somatic feedback are as part of the therapeutic and teaching process. Somatic awareness can be used as a tool to change behavior because changing the posture affects strength and recall of memories, which are important parts of the mind-body equation that underlies health and illness.
