Aim. The aim of this study was to evaluate the paravertebral left-right muscle imbalance before and after a stretching and Core-based exercise workout, aiming to represent a prophylactic tool for spine instability and lower back pain. Methods. The muscle force (mV) of the erector spine was evaluated in 3 healthy subjects, average age 25 years, using 4 EMG surface electrodes annexed to the VICON system, recordings performed before and after specific muscle training, during correct and incorrect movements with the box, means picking up and down the box and returning to orthostatic starting position. This pilot study includes a specific training program, based on specific exercises to workout muscle force and core stability, promoting rebalancing and restoring muscle force and control. We evaluated the muscle imbalance between the left and right sides. Results. We calculated the average of the muscle force (mV) imbalance and found that the difference between left and right in correct movement with the box is 0,00015mV before training and 0,000185 mV after training, which means an increase of muscle force of approximately 24%. Regarding incorrect movement with the box, we found that before the training, muscle imbalance is 0,000149 mV and after training 0,000169 mV, which means an increase in muscle force 13%. Both results demonstrated that such a training program generates an increase in muscle force and could be a way to develop a muscle training to prevent muscle imbalance and reduce the risk of spine instability. Conclusions. The proposed therapeutic approach using VICON/EMG modern devices for the capture and analysis of motion and measurement of muscular force provides consistent and valuable evaluations of different muscle' parameters and dynamic behavior.
