The Journal of Visualized Experiments (JoVE) revealed a new study that could aid in the understanding of dynamic muscle function and dysfunction during the development of musculoskeletal disorders.

Ultrasound is an attractive modality for real time non-invasive imaging of muscles and tendons in motion, however a scan’s temporal resolution is not adequate enough for highly dynamic movements such as a drop-landing or jogging.

 



The article explains. “We have developed a novel vector tissue Doppler imaging* (vTDI) technique that can be used to measure musculoskeletal contraction velocity, strain and strain rate with sub-millisecond temporal resolution during dynamic activities using ultrasound. The goal of this preliminary study was to investigate the repeatability and potential applicability of the vTDI technique in measuring musculoskeletal velocities during a drop-landing task, in healthy subjects.”

Ultrasound can potentially compliment conventional measuring techniques such as 3D motion capture, dynamometry, and electromyography. This ongoing study could provide advanced clinical research that could potentially aid in the understanding of mechanisms leading to the accelerated onset of osteoarthritis in patients or athletes who have undergone ACL reconstruction.
