A cross sectional study was conducted to determine and evaluate the effects of school bag load on electromyography (EMG) activity of the erector spinae muscle. Methods: Eighty four primary school children were selected from two national medium primary schools in Seri Kembangan, 42 from primary two (P2) and 42 from primary five (P5), aged 8 and 11 respectively. Data were collected through interviews, anthropometrics measurements, the weight of schoolbag load and surface electromyography (SEMG) of the erector spinae using muscle tester ME20000P. Surface Ag-AgCI electrodes were used to measure: unloaded standing and walking, and loaded standing and walking. Results: The study revealed that erector spinae was found to be more efficient in loaded standing probably due to other trunk muscle co-activity compared to unloaded standing (p<0.05). However, the erector spinae was less efficient when loads were carried on the back while walking, compared to unloaded walking. When the schoolbag was carried over both shoulders, forces generated by the erector spinae were reduced and resulted In more efficient use of the erector spinae compared to other asymmetrical carrying (p<0.05). conclusion: bending slightly forward when carrying schoolbag was found to reduce the forces generated by the erector spinae compared to normal sagittal posture (p<0.05), however no significant difference was found between the different frontal posture. A significant inverse relationship (p<0.01) between the weight of schoolbag load and the average electromyography (AEMG), showed that the significance of the erector spinae muscle co-activity. The study also revealed that apart from age of school children, family history of back pain, exposure to environmental tobacco smoke (ETS), weight of the schoolbag and method of carrying schoolbag also play important role as risk factors for back pain.

Background: The erector spinae plane block can be executed at various thoracic levels and in different positions. Our study aimed to determine the optimal distance of the erector spinae muscle from the skin and to identify the best ultrasonography imaging quality across different thoracic levels and positions. Materials and Methods: The erector spinae muscle was located using a high-frequency 10-15 MHz linear ultrasound probe at distinct thoracic levels (T1-T2, T5-T6, T11-T12) and in various positions (lateral, sitting, and prone). Results: The proximity of the erector spinae muscle to the skin was found to be significantly closer at the T5-T6 level compared to the T1-T2 and T11-T12 levels (p = 0.001; p < 0.01). In the prone position, the distance of the erector spinae muscle to the skin was significantly lower than in the lateral and sitting positions (p = 0.001; p < 0.01). Conclusions: In an ESPB to be applied at the T5-T6 thoracal level and in the prone position, the erector spinae muscle is closer to the skin, and the ultrasound image is better.

Introduction: Reduced invasiveness has a potential benefit of reduced postoperative pain however there is a relative paucity of prospectivedata to confirm this presumption. The analysis of this prospective study was to compare pain score results in patients who underwentminimally invasive video-assisted (MIVAT) versus minimally invasive open thyroidectomy (MIT) and in doing so further extrapolate thepotential advantages of video-assisted thyroid surgery.Materials and methods: A total of 98 patients post minimally invasive thyroidectomy from January 1st to December 31st 2008 are thesubject matter of this study. Pain scores (0-10) assigned by the patients shortly after the thyroidectomy and after 24 hours postoperativeforms the basic outcome variable. For statistical comparison of the distributions of the pain scores between patients the Kolmogrov-Smirnov (KS) test was employed.Results: The comparison pain score distribution using the KS test for postoperative assessment yielded a Z-value of 2.84 (P < 0.001).The comparison pain score distribution at 24 hours yielded a Z-value of 1.48 (P < 0.05). These results imply the difference in distributionsof pain scores among MIT and MIVAT group to be statistically significant.Conclusions: We concluded that video-assisted thyroidectomy appears to reduce the pain in patients shortly after the operation and24 hours postoperative. The reduction is statistically significant. Male patients appear to report less pain compared to their female counterparts.

Мета роботи: дослідження змін електроміографічної активності м’язів, що забезпечують стабільність крижово-клубових суглобів під час утримування вертикального осьового положення при одно- та двохопорному стоянні з вантажем та без нього при різних показниках фронтального хребтово-тазового балансу. Матеріали та методи. Було досліджено 36 практично здорових волонтерів — студентів факультету фізичної культури. У групу дослідження ввійшли 25 юнаків та 11 дівчат. Середній ріст волонтерів становив 173 см (від 168 до 183 см), середній індекс маси тіла — 2,99 (від 2,62 до 3,34). Проводили електроміографічне дослідження м’язів, підтримуючих стабільність крижово-клубових суглобів при двохопорному, одноопорному стоянні («тест лелеки»), одноопорному стоянні з вантажем 5 кг у контрлатеральній руці. Волонтер приймав необхідне положення тіла та утримував його протягом 10–15 с. Протягом цього часу записували білатерально на m. erector spinae біоелектричну активність. Використовували поверхневі електроди Skintact RT-34. Аналізували такі показники електроміо-графії: максимальну амплітуду, середню амплітуду, сумарну амплітуду та середню частоту при фільтрації частот нижче 20 Гц. Усім волонтерам робили рентгенографію таза стоячи із захватом обох кульшових суглобів. Результати. Нахил крижі та таза призводить до асиметричної активності m. erector spinae, що підвищується із збільшенням кута їх нахилу. При одноопорному стоянні за відсутності нахилу крижі та таза було відмічено підвищення активності m. erector spinae на стороні опорної кінцівки, однак збільшення кута нахилу таза в сторону опорної кінцівки призводить до збільшення активності m. erector spinae на стороні піднятої кінцівки. При посиленому варіанті виконання тесту (стоянні на одній нозі з вантажем) була виявлена більша різниця між активністю цього м’яза на стороні опорної кінцівки і активністю — піднятої кінцівки. При опорі на нижню кінцівку на стороні, протилежній нахилу, була відмічена підвищена активність m. erector spinae на опорній стороні.

We present a case of hydatid disease localized to the erector spinae muscle. A 60-year-old male was admitted to our hospital with back pain. The diagnosis was made preoperatively by US, CT, and MRI. They showed hydatid disease in erector spinae muscle. Cysts and some part of the erector spinae muscle were resected. Postoperatively pathology confirmed the diagnosis.

Surgical methods for hemorrhoid are mainly divided into two categories: traditional operation and minimally invasive operation. Traditional surgery has been widely used in clinical,with definite curative effect,but the large postoperative wound and pain cannot meet the needs of modern people. Along with the development of the concept of minimally invasive treatment,research of the treatment for hemorrhoid has been focused on all sorts of minimally invasive surgeries,such methods reduce the surgical wounds,relieve the postoperative pain,shorten the wound healing time,but their efficacy and complications caused by them still need to be further explored. Therefore,the combination of conventional surgery and minimally invasive surgery has become the new progress in surgical operation for hemorrhoid,aiming at achieving better curative effect and more perfect anal appearance,with less complications.
