| 5 | Neuromuscular trunk activation patterns in back pain patients during one-handed lifting显示文摘AIM To analyze neuromuscular activity patterns of the trunk in healthy controls(H) and back pain patients(BPP) during one-handed lifting of light to heavy loads. METHODS After assessment of back pain(graded chronic pain scale according to von Korff) all subjects(n = 43) performed a warm-up(treadmill walking). Next, subjects were instructed to lift 3 × a 20 kg weight placed in front of them(with both hand) onto a table(height: 0.75 m). Subsequently, all subjects lifted with one hand(left-side, 3 repetitions) a weight of 1 kg(light), 10 kg(middle) and 20 kg(heavy) in random order from the ground up onto the table left of them. Trunk muscle activity was assessed with a 12-lead EMG(6 ventral/6 dorsal muscles; 4000 Hz). EMG-RMS(%) was averaged over the 3 repetitions and analyzed for the whole one-handed lifting cycle, then normalized to RMS of the two-handed lifting. Additionally, the mean(normalized) EMG-RMS of four trunk areas [right/left ventral area(VR/VL); right/left dorsal area(DR/DL)] was calculated. Data were analyzed descriptively(mean ± SD) followed by student's t-test comparing H and BPP(α = 0.05). With respect to the unequal distribution of subjects in H and BPP, a matched-group analysis was conducted. Seven healthy controls were gender- and age-matched(group H_(matched)) to the 7 BPP. In addition, task failure was calculated and compared between H/H_(matched) vs BPP using χ~2. RESULTS Seven subjects(3m/4f; 32 ± 7 years; 171 ± 7 cm; 65 ± 11 kg) were assigned to BPP(pain grade ≥ 2) and 36(13m/23f; 28 ± 8 years; 174 ± 10 cm; 71 ± 12 kg) to H(pain grade ≤ 1). H and BPP did not differ significantly in anthropometrics(P > 0.05). All subjects were able to lift the light and middle loads, but 57% of BPP and 22% of H were not able to lift the heavy load(all women). χ~2 analysis revealed statistically significant differences in task failure between H vs BPP(P = 0.03). EMG-RMS ranged from 33% ± 10%/30% ± 9%(DL, 1 kg) to 356% ± 148%/283% ± 80%(VR, 20 kg) in H/BPP with no statistical difference between groups regardless of load(P > 0.05). However, the EMG-RMS of the VR was greatest in all lifting tasks for both groups and increased with heavier loads. CONCLUSION Heavier loading leads to an increase(2- to 3-fold) in trunk muscle activity with comparable patterns. Heavy loading(20 kg) leads to task failure, especially in women with back pain. | Juliane Mueller Tilman Engel Stephan Kopinski Frank Mayer Steffen Mueller | 2017 | World Journal of Orthopedics2017，8，2： | 0 |

| 7 | Acute right insular ischaemic lesions and poststroke left ventricular dysfunction显示文摘Introduction Myocardial injury related to acute ischaemic stroke is common even without primary cardiac disease.We intended to determine associations between values of left ventricular ejection fraction(LVEF)and ischaemic stroke lesion sites.Methods Of a local database,patients with acute first-ever ischaemic stroke confirmed by brain imaging but without pre-existing heart disease were included.The cardiac morphology and LVEF were obtained from transthoracic or transesophageal echocardiography,and impaired LVEF was categorised as mild(35%-50%),moderate(34%-25%)and severe(<25%).Patient age,stroke severity,ischaemic lesion volume,prevalence of troponin I increase(>0.1 ng/mL),atrial fibrillation and cardiac wall motion abnormalities were assessed and compared between patients with and without impaired LVEF after stroke(significance:p<0.05).A multivariate voxelwise lesion analysis correlated LVEF after stroke with sites of ischaemic lesions.Results Of 1209 patients who had a stroke,231(mean age 66.3±14.0 years)met the inclusion criteria;40 patients(17.3%)had an impaired LVEF after stroke.Patients with impaired LVEF had higher infarct volumes(53.8 mL vs 30.0 mL,p=0.042),a higher prevalence of troponin increase(17.5%vs 4.2%,p=0.006),cardiac wall motion abnormalities(42.5%vs 5.2%,p<0.001)and atrial fibrillation(60.0%vs 26.2%,p<0.001)than patients with LVEF of>50%.The multivariate voxelwise lesion analysis yielded associations between decreased LVEF and damaged voxels in the insula,amygdala and operculum of the right hemisphere.Conclusion Our imaging analysis unveils a prominent role of the right hemispheric central autonomic network,especially of the insular cortex,in the brain-heart axis.Our results support preliminary evidence that acute ischaemic stroke in distinct brain regions of the central autonomic network may directly impair cardiac function and thus further supports the concept of a distinct stroke-heart syndrome. | Klemens Winder Carolina Villegas Millar Gabriela Siedler Michael Knott Arnd Dörfler Anna Engel Stephan Achenbach Max J Hilz Bernd Kallmünzer Stefan Schwab Frank Seifert Kilian Fröhlich | 2023 | Stroke & Vascular Neurology2023，8，4： | 0 |
