Lateral epicondylitis, or 'tennis elbow', impacts women more often than men. Kazuhiro Ikeda & coauthors looked at potential causes for this discrepancy, finding sex differences in wrist torque and endurance: onlinelibrary.wiley.com/doi/10.1002/... #ORSxDerby #ORSSMC @jorthopres.bsky.social
(A) The wrist torque measuring equipment consists of a handle (1), a rotation center to measure wrist torque (2), and a table to place the forearms (3). (B) Subjects adjusted the moving handle to ensure the rotation center of the wrist and the rotation center of equipment together. (C) Subjects fixed their forearms on the table.

Happy to share a recent manuscript that I contributed to, "Measurement and Comparison of Hyaluronic Acid Hydrogel Mechanics Across Length Scales." Link: onlinelibrary.wiley.com/doi/epdf/10.... This work would not be possible without federal funding. #fundscience
(A) Schematic overview of the (1) sample structure (hydrogel/microgel) that is tested through (2) various testing modalities (compression/nanoindentation/micropipette aspiration) where (3) curve outputs are used to calculate the sample modulus. (B) Calculated moduli for each structure (hydrogel: gray, microgel: green), testing modality (triangle: uniaxial compression testing, square: nanoindentation, circle: micropipette aspiration), and macromer concentration (3 wt%, 4 wt%, 5 wt%; darker color = higher wt%). n = 3–5 independent samples per condition.
