USING THE BACKFIX METHOD FOR REHABILITATION AND POSTURAL CORRECTION

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.
