Shear wave tensiometry tracks reductions in collateral ligament tension due to incremental releases. [PDF]

J Orthop Res, 2023
Surgeons routinely perform incremental releases on overly tight ligaments during total knee arthroplasty (TKA) to reduce ligament tension and achieve their desired implant alignment. However, current methods to assess whether the surgeon achieved their desired reduction in the tension of a released ligament are subjective and/or do not provide a ...

Development and evaluation of ligament phantoms targeted for shear wave tensiometry. [PDF]

J Mech Behav Biomed Mater, 2022
Developing a shear wave tensiometer capable of non-invasively measuring ligament tension holds promise for enhancing research and clinical assessments of ligament function. Such development would benefit from tunable test specimens fabricated from well-characterized and consistent materials.

Atypical triceps surae force and work patterns underlying gait in children with cerebral palsy. [PDF]

J Orthop Res, 2022
Abstract The purpose of this study was to quantitatively assess Achilles tendon mechanical behavior during gait in children with cerebral palsy (CP). We used a newly designed noninvasive sensor to measure Achilles tendon force in 11 children with CP (4F, 8–16 years old) and 15 typically developing children (controls) (9F, 8–17 years old) during ...

Measurement of Achilles tendon loading using shear wave tensiometry: A reliability study

Musculoskeletal Science and Practice, 2022
Shear wave tensiometry is a recent promising technology which can be used to evaluate tendon loading. Knowing the clinimetric features (e.g., reliability) of this technology is important for use in clinical and research settings.To evaluate the inter-session reliability of a novel shear wave tensiometer for the assessment of Achilles tendon loading.

Dynamic Assembly of Microgels and Polymers at Non-Aqueous Liquid/Liquid Interfaces. [PDF]

Adv Sci (Weinh)
The assembly and jamming of PNIPAM‐co‐MAA microgels with NH2‐PDMS‐NH2 polymer ligands lead to the formation of asymmetric bilayer films at non‐aqueous liquid–liquid interfaces via non‐covalent interactions. The reversible integration of microgels and polymers enables the formatin of reconfigurable droplet networks and stimuli‐responsive non‐aqueous ...

Ionofibers: Ionically Conductive Textile Fibers for Conformal i‐Textiles

Advanced Materials Technologies, Volume 7, Issue 10, October 10, 2022., 2022
By integrating ionofibers, a new generation of ionotronics, i‐textiles, can allow for a broad range of in‐air electrochemical applications, especially with bioelectronic interfaces. To meet the fabric manufacturing requirements, ionofibers are produced to ally the mechanical properties of commercial yarns with ionic liquids via dip‐coating by ...

Feasibility of Intestinal MR Elastography in Inflammatory Bowel Disease

Journal of Magnetic Resonance Imaging, Volume 55, Issue 3, Page 815-822, March 2022., 2022
Background While MR enterography allows detection of inflammatory bowel disease (IBD), the findings continue to be of limited use in guiding treatment—medication vs. surgery. Purpose To test the feasibility of MR elastography of the gut in healthy volunteers and IBD patients. Study Type Prospective pilot.

Whispering Gallery‐Mode Microdroplet Tensiometry

Advanced Photonics Research, Volume 2, Issue 11, November 2021., 2021
A simple, fast, and very precise technique to measure time‐dependent interfacial tension between two immiscible liquids based on whispering gallery modes in micrometer droplets is demonstrated. The optical modes enable very precise measurements of the droplet size as well as the refractive index of one of the two fluids.
