The aim of this paper is to highlight the close relationship between mechanical work (J) values and functional status of the spine expressed by clinical signs such as regional pain and mobility. The group of participants is heterogeneous, consisting of 11 people who perform office work for 8 hours a day as employees of a software company. All are clinically healthy but experience temporary pain or discomfort during or at the end of the work schedule and during daily activities that involve low intensity physical exertion. They benefited from the 10 sessions of the program designed to measure, assess and enhance the statokinetic function of the spine for prevention purposes using BackFix technology. The research findings reveal an important connection between the evolution of test results and clinical manifestations.
Simulator training for swimmers is a well established practice by now. The increasingly valuable results are based on the progress of the athletes following the simulator training. The literature presents a range of training objectives and methodical instructions on its use in various stages of preparation. In terms of methodology, focus shifted on the integration of the simulator training in a training plan for swimmers designed to improve the active phase of the motion. This paper aims to achieve this objective by finding simulator load steps that are similar to the resistance to motion in water, corresponding to the different means of training. The advantage of this approach is that the simulator allows very detailed analytic measurements that cannot be performed in the natural environment. These measurements can point out the swimmers' movement stereotypes characterizing the active phase of the motion in the water - the propulsion. In order to conduct the study, a WEBA Swim model was used. The device belongs to the Performer Sport Club (Bucharest). The method depicted in this paper allows the identification of an equivalence coefficient of the strain on the simulator, comparable to the strain in water, and it consists in going through successive stages of practice and evaluating the effect of strain on the motion's structure. This equivalence allows the identification of the propulsion structure on the simulator, and the error correction in the motor execution, with a high rate of transfer in the implementation in the water. Based on the information obtained the training strain can be programmed depending on the preparation period of the athletes, and thus a better match with the competition effort can be secured.
The paper presents a particular eficient instrument for the substantial diminishing, by means of prevention (on a diagnosis and intervention related basis), of a vector with a very significant impact in terms of influencing the health state and quality of life - the deformations of the spine - with all later consequences (body aspect, pain at the osteoarticular level, degenerative diseases of internal organs). Decompensations of the statokinetic function of the spine caused by sedentary life, as well as the latter's late diagnosis, trigger in time, the installation of various pathologies as resulting out of the specialized literature. Consequences at a personal, social and economic level are huge and quite alarming. The software and the methodology proposed by SC Medisport SRL present an innovative approach which makes possible the analysis of the causal generating chain (asymmetric static postures, asymmetric walk pattern, muscle disequilibrium, functional changes of posture), points out the positioning of the muscular unbalance very close to the initiation in the causal chain, with a role in setting off or eliminating subsequent links. As a consequence, the closer the positioning of the evaluation and the corrective intervention is to the causal chain basis, the better consequences of this action are, and the prevention scope undergoes an exponential rise. It is possible to have a specialized intervention in an increasing stage, perfectly reversible at the level of a school population and professionally active adults, with a possibility of long term monitoring. Whereas the current trend in medicine, namely that of being oriented towards preventive activities, the paper is perfectly assigned to the European operational space. Because of the large interest manifested by the higher education area on this topic, the paper presents also an integration scheme of our methodology within an e-learning platform.
In this paper we aim to investigate the effectiveness of the rehabilitation and postural correction method called Backfix on a group of 20 office workers in a high-tech company, who perform their work in sitting positions over 8 hours per day. The Backfix method, which is currently the European trademark registered by MediSport SRL, has two components: the evaluation part, which measures the muscle imbalances - agonist-antagonist chains (with two coefficients) and the level of mechanical work where the balance can be achieved; and the correction part, which uses highly effective learning software to control the muscular rebalancing trajectory. All subjects have been evaluated in terms of the groups of muscles involved in maintaining the posture of the trunk, and subsequently subjected to a correction program with the following objectives: restoring the right co-operation of antagonists - agonists across the entire range of motion; making the transition from the motion programs of the articulation to the motion of the joint; improving proportional coefficient values that describe the steady state muscles of the spine; increasing the level of force and amplitude, that is, mechanical work, in which the balance of the muscles that stabilize the spine can be maintained. The results were evaluated by comparing the set of biomechanical parameters characteristic of the method (motion amplitude, mean force, maximum force, and mechanical work). The level of achievement of the motor reinforcement parameters was appreciated by a computerized scoring system. After 10 sessions of physical exercise, the subjects have been re-assessed. The result analysis indicates a positively significant evolution of the whole group for all parameters demonstrating the ability of the method to efficiently cover a very wide range of variables as age, gender, personal history, etc., which are normal in a functional group of people with office work.
