Biomechanics, the study of the structure and function of biological systems through the methods of mechanics, is a pivotal area in sports science, rehabilitation, and ergonomics. With Noraxon‘s state-of-the-art technology, professionals across these fields can access precise data on human movement and muscle activity, enhancing performance, accelerating recovery, and preventing injuries. Accordingly, this guide explores Noraxon leading systems — the Ultium Motion 3D Motion Capture/IMU System, Ultium Wireless EMG, Core EMG, and Ultium Portable Lab — alongside essential accessories like SmartLeads, helping you select the perfect setup for your biomechanical analysis needs.
Understanding the Basics: IMU vs. EMG
Before diving into specific systems, it’s crucial to grasp the fundamental differences between Inertial Measurement Units (IMUs) and Electromyography (EMG). Understanding the basics of IMU (Inertial Measurement Unit) and EMG (Electromyography) involves recognising their distinct roles in measuring different aspects of human movement.
IMU focuses on capturing motion and orientation data by utilising accelerometers, gyroscopes, and sometimes magnetometers. Therefore, it measures linear acceleration, angular velocity, and magnetic fields to track changes in position, velocity, and orientation. IMUs are commonly used in applications such as navigation systems for vehicles, drones, and wearable devices for activity tracking and virtual reality.
On the other hand, EMG is concerned with recording the electrical activity generated by muscles during contraction. It involves placing electrodes on the skin or directly into muscles to measure muscle activation, timing, and intensity. EMG is valuable for diagnosing neuromuscular disorders, assessing muscle function in rehabilitation, and studying muscle activity during movement and exercise.
In summary, IMU measures motion and orientation using inertial sensors, while EMG records muscle activity through electrical signals. Both technologies provide valuable insights into human movement, with applications ranging from sports science and biomechanics to healthcare and rehabilitation. Understanding their differences allows for their effective use in various fields to analyse and optimise human performance and health.1
