Inside the Current Generation Biomechanics Lab: Key Devices and Their Costs

Biomechanics labs are critical in understanding human movement, diagnosing disorders, and developing rehabilitation strategies. These labs are equipped with advanced technology to capture and analyze the intricacies of human motion. In this blog post, we’ll explore the essential devices found in a traditional biomechanics lab and their associated costs.

1. Motion Capture Systems

Motion capture systems are used to capture and analyze the movements of the human body in three dimensions. These systems typically employ multiple high-speed cameras placed around the subject, who is fitted with reflective markers or sensor-based suits. The cameras track the positions of these markers to generate detailed, three-dimensional data on the subject’s movements. This technology is widely used in fields such as biomechanics, sports science, animation, and rehabilitation to provide precise measurements and analyses of motion.

2. Force Plates

Force plates are devices used to measure the ground reaction forces generated by a subject standing, walking, or performing other movements across them. They are essential tools in biomechanics for analyzing balance, gait, and athletic performance. By capturing data on the forces exerted by the feet on the ground, force plates help researchers and clinicians understand how forces are distributed and how the body responds to different activities.

3. Electromyography (EMG) Systems

Electromyography (EMG) systems measure the electrical activity produced by skeletal muscles. This technique is used to analyze muscle function, diagnose neuromuscular disorders, and assess muscle response during rehabilitation exercises. EMG can be performed using surface electrodes placed on the skin or intramuscular electrodes inserted into the muscle tissue. The data collected provides insights into muscle activation patterns, timing, and fatigue.

4. 3D Motion Analysis Software

3D motion analysis software processes and analyzes the data captured by motion capture systems to create detailed three-dimensional models of movement. This software is essential for visualizing, quantifying, and interpreting complex motion patterns. It allows researchers and clinicians to assess joint angles, velocities, and accelerations, providing valuable information for diagnosing movement disorders and optimizing performance.

5. Instrumented Treadmills

Instrumented treadmills are treadmills equipped with integrated force plates or pressure sensors. These devices allow for the detailed analysis of gait and running mechanics in a controlled environment. By measuring forces and pressure distribution during walking or running, instrumented treadmills provide critical data for assessing and improving gait patterns, diagnosing issues, and enhancing athletic performance.

6. Wearable Inertial Measurement Units (IMUs)

Wearable Inertial Measurement Units (IMUs) are portable sensors that measure acceleration, angular velocity, and magnetic field strength. These devices are worn on the body to track movements in various activities. IMUs provide detailed motion data that can be used for gait analysis, sports performance monitoring, and remote patient assessment. They offer a versatile and cost-effective alternative to traditional motion capture systems.

7. Pressure Mapping Systems

Pressure mapping systems use pressure-sensitive mats or insoles to measure the distribution of pressure across the feet during various activities. These systems provide high-resolution data on how forces are distributed across the feet, which is useful for analyzing gait, improving footwear design, and diagnosing foot disorders. The data can be visualized in real-time, allowing for immediate feedback and adjustments.

Summary Table: Devices and Costs in a Traditional Biomechanics Lab

Conclusion

A traditional biomechanics lab is equipped with a range of advanced devices designed to measure and analyze human movement with high precision. From motion capture systems to force plates, these tools provide invaluable data for research and clinical applications. The challenge has been the overwhelming costs of implementing the tools and the time is takes to collect and analyze the volume of biomechanics data that they can generate.

Advances in technology, from wearable sensors to cloud computing and artificial intelligence are making insights from biomechanics data more accessible in more places and in subsequent posts you will see how FIGUR8 is revolutionizing the field through technological innovation and seamless implementation into clinical workflows to deliver value to patients, providers, and payers.

    Musculoskeletal injury – The (not-so) straight line of recovery and rehabilitation

    Taken from Aeromith’s seminal 90s album “Get a Grip”, this same quote could be applied to the rehabilitation journey of many individuals recovering from a musculoskeletal injury. In my past life as a physical therapist, I had countless patients arrive at their appointments and share that today “[they] just feel weaker” or “[their insert area of the body here] just feels less stable” and the tools that I had at my disposal ranged from asking questions and getting a subjective response as to why they felt this way, or just as rudimentary, using manual muscle tests to determine, if in fact, there was a change in their strength. Looking at the table below, which shows the scoring rubric for manual muscle tests, you’ll understand my challenge.
