I love my job... no, no, not this time ;) I love my hobby, too :)

Fellows from Harvard University in Cambridge, MA, USA, are using opbox and opmux to drive innovation in the field of estimating joint torque in dynamic activities using wearable A-mode ultrasound. You can explore their groundbreaking work published in Nature Communications, Volume 15, Article Number 5756 (2024). Imagine the possibilities with opbox in your hands. Whether you're working on an innovative drone for at-height NDT inspections (https://lnkd.in/d-kvjv7w), or on the system for manual spot weld testing enhanced by AI software (https://lnkd.in/dp9DNhzb), material analysis, or any other high-tech application, opbox can elevate your projects to new heights. How will you use opbox (with opmux) to revolutionize your work? Let us help you unlock its full potential and achieve your goals.

Estimation of joint torque in dynamic activities using wearable A-mode ultrasound Yichu Jin, Jonathan T. Alvarez, Elizabeth L. Suitor, Krithika Swaminathan, Andrew Chin, Umut S. Civici, Richard W. Nuckols, Robert D. Howe & Conor J. Walsh Nature Communications volume 15, Article number: 5756 (2024) Abstract The human body constantly experiences mechanical loading. However, quantifying internal loads within the musculoskeletal system remains challenging, especially during unconstrained dynamic activities. Conventional measures are constrained to laboratory settings, and existing wearable approaches lack muscle specificity or validation during dynamic movement. Here, we present a strategy for estimating corresponding joint torque from muscles with different architectures during various dynamic activities using wearable A-mode ultrasound. We first introduce a method to track changes in muscle thickness using single-element ultrasonic transducers. We then estimate elbow and knee torque with errors less than 7.6% and coefficients of determination (R2) greater than 0.92 during controlled isokinetic contractions. Finally, we demonstrate wearable joint torque estimation during dynamic real-world tasks, including weightlifting, cycling, and both treadmill and outdoor locomotion. The capability to assess joint torque during unconstrained real-world activities can provide new insights into muscle function and movement biomechanics, with potential applications in injury prevention and rehabilitation. https://lnkd.in/dzgz-4mz
