Disease diagnosis still remains challenging in many cases and is frequently delayed. The purpose of this study was to determine the most common comorbidities in lipedema patients and the impact of surgical treatment onto disease progression. A retrospective assessment of disease-related epidemiologic data was performed for patients who underwent liposuction between July 2009 and July 2019 in a specialized clinic for lipedema surgery. All patients received a standardized questionnaire regarding the clinical history and changes of lipedema-associated symptoms and comorbidities after surgery. 106 patients who underwent a total of 298 liposuction procedures were included in this study after returning the questionnaire fully filled-in. Multiple comorbidities were observed in the assessed collective. The prevalence for obesity, hypothyroidism, migraine, and depression were markedly increased in relation to comparable nonlipedema populations. Despite a median body mass index (BMI) of 31.6 kg/m(2) (IQR 26.4-38.8), unexpected low prevalence of diabetes (5\%) and dyslipidemia (7\%) was found. Diagnosis and initiation of guideline-appropriate treatment were delayed by years in many patients. After surgical treatment (medium follow-up 20 months, IQR 11-42), a significant reduction of lipedema-associated symptoms was demonstrated. Lipedema occurs with a diversity of associated comorbidities. Therefore, on the basis of available data, the authors suggest the necessity of a multimodal therapy concept for a comprehensive and holistic treatment. Despite a commonly increased BMI, lipedema patients appear to have an advantageous metabolic risk profile.}, language = {en} } @article{KellisEllinoudisIntziegiannietal.2020, author = {Kellis, Eleftherios and Ellinoudis, Athanasios and Intziegianni, Konstantina and Kofotolis, Nikolaos}, title = {Muscle thickness during core stability exercises in children and adults}, series = {Journal of human kinetics}, volume = {71}, journal = {Journal of human kinetics}, number = {1}, publisher = {Academy of Physical Education}, address = {Katowice}, issn = {1640-5544}, doi = {10.2478/hukin-2019-0079}, pages = {131 -- 144}, year = {2020}, abstract = {Core stability exercises are regular part of exercise programs for asymptomatic individuals across ages. The purpose of this study was to examine deep abdominal and multifidus muscle thickness in children and adults and to determine reliability of the rehabilitative ultrasound (RUSI) imaging. Transversus abdominis and lumbar multifidus thickness at rest and during core stability exercise were examined in pre-pubertal children (N = 23), adolescents (N = 20), young adults (N = 21) and middle-aged adults (N = 22). Thirty-nine participants were re-tested one week after to establish reliability. Muscle thickness at rest was lower in children and adolescents compared with young and middle-aged adults (p < 0.008). Young adults displayed the highest relative transversus abdominis thickness upon contraction (p < 0.008). Lumbar multfidus contraction thickness was greater in young-adults than middle-aged adults and prepubertal children (p < 0.008), but it was similar between young-adults and adolescents (p > 0.008). Reliability was high for both muscles (ICC3,3 = 0.76 - 0.99). The age-related differences in muscle thickness indicate that core stability exercises may be beneficial for children and middle-aged adults.}, language = {en} } @article{WochatzEngelMuelleretal.2020, author = {Wochatz, Monique and Engel, Tilman and M{\"u}ller, Steffen and Mayer, Frank}, title = {Alterations in scapular kinematics and scapular muscle activity after fatiguing shoulder flexion and extension movements}, series = {Medicine and science in sports and exercise : MSSE}, volume = {52}, journal = {Medicine and science in sports and exercise : MSSE}, number = {17}, publisher = {Lippincott Williams \& Wilkins}, address = {Philadelphia}, issn = {0195-9131}, doi = {10.1249/01.mss.0000676540.02017.2c}, pages = {274 -- 274}, year = {2020}, abstract = {Repetitive overhead motions in combination with heavy loading were identified as risk factors for the development of shoulder pain. However, the underlying mechanism is not fully understood. Altered scapular kinematics as a result of muscle fatigue is suspected to be a contributor. PURPOSE: To determine scapular kinematics and scapular muscle activity at the beginning and end of constant shoulder flexion and extension loading in asymptomatic individuals. METHODS: Eleven asymptomatic adults (28±4yrs; 1.74±0.13m; 74±16kg) underwent maximum isokinetic loading of shoulder flexion (FLX) and extension (EXT) in the sagittal plane (ROM: 20- 180°; concentric mode; 180°/s) until individual peak torque was reduced by 50\%. Simultaneously 3D scapular kinematics were assessed with a motion capture system and scapular muscle activity with a 3-lead sEMG of upper and lower trapezius (UT, LT) and serratus anterior (SA). Scapular position angles were calculated for every 20° increment between 20-120° humerothoracic positions. Muscle activity was quantified by amplitudes (RMS) of the total ROM. Descriptive analyses (mean±SD) of kinematics and muscle activity at begin (taskB) and end (taskE) of the loading task was followed by ANOVA and paired t-tests. RESULTS: At taskB activity ranged from 589±343mV to 605±250mV during FLX and from 105±41mV to 164±73mV during EXT across muscles. At taskE activity ranged from 594±304mV to 875±276mV during FLX and from 97±33mV to 147±57mV during EXT. Differences with increased muscle activity were seen for LT and UT during FLX (meandiff= 141±113mV for LT, p<0.01; 191±153mV for UT, p<0.01). Scapula position angles continuously increased in upward rotation, posterior tilt and external rotation during FLX and reversed during EXT both at taskB and taskE. At taskE scapula showed greater external rotation (meandiff= 3.6±3.7°, p<0.05) during FLX and decreased upward rotation (meandiff= 1.9±2.3°, p<0.05) and posterior tilt (meandiff= 1.0±2.1°, p<0.05) during EXT across humeral positions. CONCLUSIONS: Force reduction in consequence of fatiguing shoulder loading results in increased scapular muscle activity and minor alterations in scapula motion. Whether even small changes have a clinical impact by creating unfavorable subacromial conditions potentially initiating pain remains unclear.}, language = {en} }
