Reactive balance control in older adults with diabetes.
Gait & posture
Dec 30, 2017
Diabetes mellitus is a major health problem for older adults worldwide and could be associated with impaired ability to recover balance after postural disturbances. This study compared reactive balance control in three groups of adults, young (YA), h...
Platelet-rich plasma inhibits Wnt/β-catenin signaling in rabbit cartilage cells activated by IL-1β.
International immunopharmacology
Dec 30, 2017
OBJECTIVE: Platelet-rich plasma (PRP) has been reported to alleviate degenerative pathological damage to joint cartilage. This study aimed to investigate the effect of PRP on Wnt/β-catenin signaling in rabbit chondrocytes.
Anatomic and non-anatomic anterior cruciate ligament posterolateral bundle augmentation affects graft function.
Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA
Jul 29, 2017
PURPOSE: The purpose of this study is to compare knee laxity and graft function (tissue force) between anatomic and non-anatomic posterolateral (PL) bundle augmentation.
Effect of body weight support variation on muscle activities during robot assisted gait: a dynamic simulation study.
Computer methods in biomechanics and biomedical engineering
Feb 9, 2017
BACKGROUND AND OBJECTIVES: While body weight support (BWS) intonation is vital during conventional gait training of neurologically challenged subjects, it is important to evaluate its effect during robot assisted gait training. In the present researc...
Design and Characterization of an Exoskeleton for Perturbing the Knee During Gait.
IEEE transactions on bio-medical engineering
Jan 20, 2017
OBJECTIVE: An improved understanding of mechanical impedance modulation in human joints would provide insights about the neuromechanics underlying functional movements. Experimental estimation of impedance requires specialized tools with highly repro...
Is an Anterolateral Ligament Reconstruction Required in ACL-Reconstructed Knees With Associated Injury to the Anterolateral Structures? A Robotic Analysis of Rotational Knee Stability.
The American journal of sports medicine
Jan 5, 2017
BACKGROUND: The effect of an anterolateral ligament (ALL) reconstruction on rotational knee stability and corresponding anterior cruciate ligament (ACL) graft forces using multiple knee loading conditions including the pivot-shift phenomenon has not ...
How Much Does the Anatomical Tibial Component Improve the Bony Coverage in Total Knee Arthroplasty?
The Journal of arthroplasty
Dec 27, 2016
BACKGROUND: Recently, anatomical designs in total knee arthroplasty are introduced to address asymmetry of the resected tibia cutting surface. It is still not well known how much improvement would be achieved in total knee arthroplasty, especially in...
Tenascin-C Prevents Articular Cartilage Degeneration in Murine Osteoarthritis Models.
Cartilage
Dec 4, 2016
Objective The objective of this study was to determine whether intra-articular injections of tenascin-C (TNC) could prevent cartilage damage in murine models of osteoarthritis (OA). Design Fluorescently labeled TNC was injected into knee joints and i...
Delaying Ambulation Mode Transition Decisions Improves Accuracy of a Flexible Control System for Powered Knee-Ankle Prosthesis.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
Sep 22, 2016
Powered lower limb prostheses can assist users in a variety of ambulation modes by providing knee and/or ankle joint power. This study's goal was to develop a flexible control system to allow users to perform a variety of tasks in a natural, accurate...
