The effect of powered ankle prostheses on muscle activity during walking.

J Biomech 2021 Jun 11;124:110573. Epub 2021 Jun 11.

School of Kinesiology, University of Michigan, Ann Arbor, MI, USA; Department of Biomedical Engineering, University of Michigan, Ann Arbor, MI, USA. Electronic address:

Individuals with transtibial amputation (TTA) walk with greater muscle activity and metabolic costs than non-amputees. Powered prostheses aim to address these deficits by replicating the active function of the biological ankle. The purpose of this study was to determine if people with TTA alter muscle activity when walking with a powered prosthesis, and if this change relates to changes in metabolic costs. Read More

Cueing Changes in Peak Vertical Ground Reaction Force to Improve Coordination Dynamics in Walking.

J Mot Behav 2021 Jun 20:1-10. Epub 2021 Jun 20.

Department of Exercise and Sport Science, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina.

AbstractsBiofeedback has been effectively implemented to improve the mediation and distribution of joint loads during gait, however, the inability to effectively coordinate lower limb movement by altering loading patterns may increase pathological stress and risk of injury and deleterious joint changes. This study examined the influence cueing an increase or decrease in lower extremity loading has on inter- and intralimb joint coordination during gait, applied herein for 12 persons following anterior cruciate ligament reconstruction across three loading conditions (control, high, and low). Visual biofeedback was presented on a screen via a force-measuring treadmill with targeted changes prescribed based on stride-to-stride peak vertical ground reaction forces bilaterally. Read More

Low Molecular Weight Supramolecular Hydrogels for Sustained and Localized Drug Delivery.

ACS Appl Bio Mater 2019 Apr 20;2(5):2116-2124. Epub 2019 May 20.

Department of Chemistry, University of Rochester, Rochester, NY 14627.

Supramolecular hydrogels are emerging as next-generation alternatives to synthetic polymers for drug delivery applications. Self-assembling peptides are a promising class of supramolecular gelator for drug delivery that have been slow to be adopted despite advantages in biocompatibility due to the relatively high cost of producing synthetic peptide hydrogels compared to synthetic polymer gels. Herein we describe the development and use of inexpensive low molecular weight cationic derivatives of phenylalanine (Phe) as injectable hydrogels for delivery of an anti-inflammatory drug, diclofenac, for pain mitigation in a mouse model.

Strain patterns in normal anterior talofibular and calcaneofibular ligaments and after anatomical reconstruction using gracilis tendon grafts: A cadaver study.

BMC Musculoskelet Disord 2021 Jun 18;22(1):558. Epub 2021 Jun 18.

Division of Orthopaedic Surgery, Dalhousie University, Queen Elizabeth II Health Sciences Center Halifax Infirmary (Suite 4867), 1796 Summer Street, Halifax, NS, B3H3A7, Canada.

Background: Inversion ankle sprains, or lateral ankle sprains, often result in symptomatic lateral ankle instability, and some patients need lateral ankle ligament reconstruction to reduce pain, improve function, and prevent subsequent injuries. Although anatomically reconstructed ligaments should behave in a biomechanically normal manner, previous studies have not measured the strain patterns of the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) after anatomical reconstruction. This study aimed to measure the strain patterns of normal and reconstructed ATFL and CFLs using the miniaturization ligament performance probe (MLPP) system. Read More
