Background. The study aims to evaluate the effect of the pelotherapy in the treatment of patients with lumbar discopathy treated with low-frequency magnetic field and kinesitherapy. Material and methods. The study involved 79 persons randomly divided into 2 groups. The patients from group I (39 individuals) were subjected to pelvic therapy, low-frequency magnetic field and kinesitherapy. Those in the other group (40 individuals) were exposed to low-frequency magnetic field and kinesitherapy. To compare and assess the changes in both samples, the VAS pain scale and the Roland-Morris Disability Index were used, as well as the fingers-floor test to examine the range of mobility. Results. There were no statistically significant differences between the examined groups (p> 0.05). Both groups benefited from the therapy. In the first one, there was a reduction in pain − Me = 1.0 point in the VAS scale and, according to the Roland-Morris Questionnaire, the degree of disability was reduced by Me = 1.0 point. A more significant increase in the range of motion of the lumbar spine was observed in group II, in which the range of mobility increased by Me = 2.0 cm in the fingers-to-floor test. Conclusions. I ncorporation o f a pelotherapy i nto t he t reatment w hich c onsisted o f l owfrequency magnetic field and kinesitherapy did not significantly result in achieving a better therapeutic outcome.
To precisely evaluate low back pain, identification of the detailed innervation of the lumbar spine is necessary. On twenty-five sides of adult cadavers we investigated various patterns of rami communicantes (RC) and their relationship to the psoas major muscle (PM). In ten sides, we focused our dissection on the minute nerve supply of the anterior (ALL) and posterior longitudinal ligaments (PLL), vertebral bodies and the intervertebral discs (IVD). According to the mode of piercing PM, two types of RC were observed: superficial oblique rami (SOR) and deep transverse rami (DTR). SOR ran obliquely between superficial heads of PM, connecting sympathetic trunk (ST) and T12-L2 (3) spinal nerves non-segmentally. DTR ran segmentally close to the vertebral bodies and were situated deep to the PM slips. On the lateral side of the lumbar spine, the vertebral bodies and IVD received branches from DTR and ventral rami segmentally, as well as branches from the sympathetic trunk (ST) and, in the upper lumbar region, SOR non-segmentally. On the anterior aspect of the lumbar spine, ALL received branches from ST and splanchnic nerves non-segmentally. Within the vertebral canal, the posterior aspect of IVD and PLL received the sinu-vertebral nerves originating from DTR. These findings suggest the coexistence of two different types of innervation: one originating directly from the spinal nerve segmentally, and one reaching vertebral structures via the sympathetic nerves non-segmentally. Therefore, sympathetic nerves are likely involved in the proprioception of the spinal column.

Biomechanical characteristics of rowing

86%
Competitive rowing demands long-term, unilateral and nonphysiological training. This discipline requires not only technical preparation, but also strength and endurance training, which is largely conducive to the occurrence of micro-traumas that can cumulate and lead to a spectrum of overloading changes in the motor organs, particularly in the lumbar spine. The factor most conducive to the occurrence of pathological changes in the spine is the rowing cycle, both on water and on ergometer, wherein the athlete performs multiple repetitions of maximum flexion and extension in the sagittal plane of the lumbar spine. Of note is the fact that during a single, 90-minute training session the rower engages over 70% of his or her overall muscle mass, performing 1800 cycles of flexion and extension. These motions performed with oars as additional weights lead to the overloading of both the active and the passive spine stabilization system. Moreover, the system is impacted by compression forces in excess of 6000 N that can lead to destruction of the motor system. It is therefore necessary to understand the biomechanics of spine movements and to perform the biomechanical analysis of rowing, as well as use conclusions from the analysis in the training process in order to counteract overloading changes in the motor system, particularly the spine.
Introduction and objective: Back pain are the most common ailment within the human locomotor system. Because of their prevalence, they were classified as diseases of civilization. The aim of the study was to attempt to assess the concentration of selected amino acids in plasma and correlating the results of laboratory tests with the occurrence of backaches. Material and method: The study group included 188 patients presenting for CT scan administering as the cause of their symptoms low back pains. All of these patients gave the blood samples from which the concentration of free amino acids was estimated by ion exchange chromatography using an automated amino acid analyzer AAA 400 from INGOS Praha. The control group consisted of patients who underwent testing using computed tomography and there were no primary or secondary changes associated with degeneration in the lumbar spine. Results: Patients on the basis of research carried out by computed tomography were divided into five groups according to disease entity. Analyzing the average concentration of essential amino acids in the blood plasma of patients of each group, it was found that it is higher in the case of lysine for each considered disease entity. The average concentration of methionine in all disease entities does not deviate from the average values in the control group. Analysis of the average concentration of selected essential amino acids revealed that in the case presented disorders underwent their level of variation. Average concentrations of selected amino acids have proven to be very similar in both groups. Slightly higher values proved to be in the control group for proline and lysine. Conclusions: The concentration of amino acids varies with the severity of degenerative changes in the connections as well as in interbody joints. The highest increase in the concentrations of all tested amino acids are present in root bands. Decrease in the concentrations of all tested amino acids appears in cancer.
