• Magnetomicrometry

  Science Robotics · 2022 · 43 citations

  We live in an era of wearable sensing, where our movement through the world can be continuously monitored by devices. Yet, we lack a portable sensor that can continuously monitor muscle, tendon, and bone motion, allowing us to monitor performance, deliver targeted rehabilitation, and provide intuitive, reflexive control over prostheses and exoskeletons. Here, we introduce a sensing modality, magnetomicrometry, that uses the relative positions of implanted magnetic beads to enable wireless tracki…

• Conference report on contractures in musculoskeletal and neurological conditions

  Muscle & Nerve · 2020 · 21 citations

  Limb contractures are debilitating complications associated with various muscle and nervous system disorders. This report summarizes presentations at a conference at the Shirley Ryan AbilityLab in Chicago, Illinois, on April 19-20, 2018, involving researchers and physicians from diverse disciplines who convened to discuss current clinical and preclinical understanding of contractures in Duchenne muscular dystrophy, stroke, cerebral palsy, and other conditions. Presenters described changes in mus…

• Collagen type VI regulates TGF-β bioavailability in skeletal muscle in mice

  Journal of Clinical Investigation · 2025-05-01 · 11 citations

  articleOpen access

  Collagen VI-related disorders (COL6-RDs) are a group of rare muscular dystrophies caused by pathogenic variants in collagen VI genes (COL6A1, COL6A2, and COL6A3). Collagen type VI is a heterotrimeric, microfibrillar component of the muscle extracellular matrix (ECM), predominantly secreted by resident fibroadipogenic precursor cells in skeletal muscle. The absence or mislocalization of collagen VI in the ECM underlies the noncell-autonomous dysfunction and dystrophic changes in skeletal muscle w…

• The interaction of <i>in vivo</i> muscle operating lengths and passive stiffness in rat hindlimbs

  Journal of Experimental Biology · 2024-02-14 · 5 citations

  articleOpen accessSenior author

  The operating length of a muscle is a key determinant of its ability to produce force in vivo. Muscles that operate near the peak of their force-length relationship will generate higher forces whereas muscle operating at relatively short length may be safe from sudden lengthening perturbations and subsequent damage. At longer lengths, passive mechanical properties have the potential to contribute to force or constrain operating length with stiffer muscle-tendon units theoretically being restrict…
