In this webinar, Dylan Sarver and Matthew Borkowski present new research in tendon physiology and demonstrate how to measure the mechanical properties of tendon and connective tissue samples using a novel Dual-Mode Lever System.

On May 16, 2017, InsideScientific and sponsor Aurora Scientific hosted a webinar showing how to study the mechanical properties of tendon. Presenters Dylan Sarver of the University of Michigan and Matthew Borkowski of Aurora Scientific discuss tendinopathies, key principles, data analysis, and results of recent tendon research.

Matthew Borkowski introduces the Aurora Scientific Dual Mode Lever, discusses how to characterize the structural and functional properties of tendon, and demonstrates how to control and synchronize stretch, slack, and instantaneous tensile force using DMC software, and provides a list of standard experiments possible using this technology.

Following, Dylan Sarver describes his research, discussing gender differences in the properties in tendon. He reviews histology, a mechanics overview, and uses video to demonstrate tendon isolation, fixation, and measuring cross-sectional area. Finally, he shows his data, including stress-strain curves and a comparison of proteomics.

This is an essential webinar for researchers interested in studying connective tissue, muscle function/physiology, and tendon.
