Surface Electromyography Data Analysis for Evaluation of Physical Exercise Habits between Athletes and Non-Athletes during Indoor Rowing.

In this paper, surface electromyography (sEMG) is used to gather the activation neural signal from muscles during an indoor rowing exercise. The exercise was performed by professional athletes and amateur non-athletes. The data acquisition and processing are described to obtain a set of parameters: number of cycles, average cycle time, cycle time standard deviation, fatigue time, muscle activation time, and muscle energy. These parameters are used to draw conclusions on common non-athletes' mistakes during exercise for better training advice and a way of statistically distinguishing an athlete from a non-athlete.

Congenital radioulnar synostosis - case report.

BACKGROUND: Congenital radioulnar synostosis is a rare malformation of the upper limb, with functional limitations of the limb. CASE REPORT: A 10-year-old child with pain and restricted mobility of the elbow joint was admitted to the hospital. Plain film radiography and CT examination was performed. Radiological examinations showed a congenital radioulnar synostosis. The child underwent surgical treatment - derotational osteotomy. CONCLUSIONS: Diagnostic imaging including computed tomography with three-dimentional (3D) reconstructions, preceding surgery enables planning of the surgical treatment.

[Epidemiological analysis of posttraumatic cervical spine injury]. / Analiza epidemiologiczna pourazowych uszkodzen kregoslupa szyjnego.

The purpose of this study was epidemiological analysis of trauma causes and trauma effects including age and sex. 112 patients after cervical spine trauma, admitted in Emergency Room of Self-Financing Public District Hospital of Trauma Surgery at Piekary Slaskie were studied retrospectively. The following parameters were estimated: age, sex, cause of injury, type and localization of pathology. The mean age was 35.4 years. The largest age group consisted of patients 25-45 years old. Males predominated over females in all age groups. The most common cause of cervical spine injury was traffic accident with a patient as a car driver or as a car passenger (45.5%) The most common pathology was luxation and subluxation (36.6%). Luxations and subluxations were most often localized on C1-C2 level (50.6% of all luxations), and on C5-C6 level (19.8% of all luxations). Fractures were most often localized in C5 vertebra (24.8% of all fractures). These results suggest that causes and results of trauma and participation of both sex have changed.

[Evaluation of upper cervical spine injury (C1-C2) with computed tomography]. / Ocena zmian pourazowych krekgoslupa szyjnego na poziomie C1-C2 na podstawie tomografii komputerowej.

Cervical spine injuries are common and essential diagnostic problem. Diagnostic imaging is necessary for proper and effective treatment. Helical computed tomography (CT) and plain radiography are the basic diagnostic methods in cervical spine injuries. The purpose of this work was the comparison of CT examination of the upper cervical spine (CI-C2) with patients' clinical state. Twenty four patients (17 men and 7 women) were introduced into the study. The most common cause of cervical spine injuries were car accidents (48.5%). CT examination was performed in all patients. Six patients (25%) had multilevel injury, localized at C1-C2 level and in the lower part of cervical spine. The main pathology diagnosed by CT in the studied group was rotatory subluxation (66.6%). Eight patients (33.3%), with rotatory subluxation did not present any abnormalities in neurological examination performed immediately after the admission to the hospital. C1 and/or C2 fractures were diagnosed in 11 patients (45.8%), in some cases (in 3 patients - 12.5%) they were accompanied by rotatory subluxations. CT examination is the basic technique of diagnostic imaging in a case of cervical spine injuries. It enables quick, accurate and precise evaluation of bone structures and surrounding soft tissues. CT also enables multiplanar imaging and 3-dimentional imaging.

[Usefulness of computed tomography with three-dimensional reconstructions in visualization of cervical spine malformation of a child with Sprengel's deformity]. / Przydatnosc badania TK z rekonstrukcja trójwymiarowa w obrazowaniu anomalii kostnej krvgoslupa szyjnego u dziecka z zespolem sprengela.

The Sprengel's deformity is a congenital anomaly of the shoulder girdle with an elevation of the scapula and limitation of movement of the shoulder. Sprengel's deformity is frequently associated with cervical spine malformations such as: spinal synostosis, spina bifida and an abnormal omovertebral fibrous, cartilaginous or osseus connection. The diagnosis of Sprengel's deformity is based on a clinical examination and radiological procedures. In every case of Sprengel's deformity plain radiography and computed tomography should be performed. Three-dimensional (3D) reconstructions allow to visualize precise topography and spatial proportions of examined bone structures. 3D reconstruction also enables an optional rotation of visualized bone structures in order to clarify the anatomical abnormalities and to plan surgical treatment.
