Exploiting the concept of hysteresis in ankle dysfunction and ankle strengthening
The ankle joint is an important part of the body which is responsible for normal gait cycle. Dorsiflexion, plantar flexion, inversion and eversion are four types of movements controlled by the ankle joint. All these movements are controlled by the ligaments and the muscles associated with the …

Validation of the Ottawa Ankle Rules for Acute Foot and Ankle Injuries
Context: The original and modified Ottawa Ankle Rules (OARs) were developed as clinical decision rules (CDRs) for the emergency department setting. However, these CDRs have not been validated as an acute clinical evaluation tool. Currently, there are no sport-specific CDRs relating to acute ankle …

Ankle Kinetics During Landing Tasks in Participants with Chronic Ankle Instability and Uninjured Controls
Lateral ankle sprains are a common injury sustained by physically active individuals. Many of these individuals will incur repetitive episodes of lateral ankle sprain, resulting in chronic ankle instability (CAI). CAI has been heavily researched, but few conclusions have been drawn. Much of this …

Ankle mechanical impedance under muscle fatigue
This study reports the effects of ankle muscle fatigue on ankle mechanical impedance. It suggests that decreasing ankle impedance with muscle fatigue may contribute to an increased probability of ankle injury. If confirmed, this observation may have important athletic, military and clinical …

Simulating control of the ankle joint
… this need. Models and simulations of the human ankle were created in PyODE. This program is useful for creating simple models where the programmer desires a high level of control over model parameters. Simulations of the ankle kicking a ball and taking a step were created to examine the effect …

A Dynamic Ankle Orthosis for Alleviating Mechanical Foot and Ankle Pain, Preserving Joint Motion, and Restoring Patient Function
… visit the doctor each year for foot and ankle pain stemming from a degenerative condition or injury. Standard of care ankle-foot orthoses have been shown to effectively manage pain symptoms of the lower limb, but they can also significantly hinder joint motion and limit function. The …

EMG control of prosthetic ankle plantar flexion
Similar to biological human ankle, today's commercially available powered ankle-foot prostheses can vary impedance and deliver net positive ankle work. These commercially available prostheses are intrinsically controlled. Users cannot intuitively change ankle controller's behavior to perform …

Effects of Hip Rehabilitation Intervention on Dynamic Postural Control and Self-Reported Ankle Impairment in Patients with Chronic Ankle Instability
… disability in patients with chronic ankle instability (CAI). Design and Setting: A double blinded, randomized control trial was conducted in a laboratory setting. Subjects: Twelve patients with CAI were randomly assigned to an Ankle intervention group (4 males, 2 females; 21.5±2.81 …

Effects of a Tape Cast, Air-Stirrup, and an Air-Stirrup Applied Over a Taped Ankle on Dynamic Ankle Inversion
… alone with respect to their effects on dynamic ankle inversion.</p> <p>Design and Setting: This study used a repeated measures design with the independent variables being the exercise bout and the ankle support method (4 levels: no support, Air-Stirrup only, Air-Stirrup/closed basketweave, and …

Beneath the light: stage-bound and ankle-cuffed
… the title of "Beneath the Light, Stage-bound and Ankle-cuffed" is chapbook-length manuscript with two sections. The first section has a focus on famous actors and actresses on the stage and in film, and the second section enters the area of the housewife and the everyday woman with specific cases …

Kinematic study of human ankle control during walking
In order to determine the extent to which ankle motion is voluntarily controlled during walking, angular velocity measurements at the ankle were taken in two cases. In the first case, subjects were seated and instructed to move their ankle as quickly as possible in eight directions indicated by a …

A Comparison of Strength, ROM, Laxity, and Static and Dynamic Postural Control Between Ankle Copers and Patients With Chronic Ankle Instability
… of this study was to examine differences between ankle sprain copers and those with CAI in selected measures that are known to differentiate CAI and healthy individuals. Increased ankle laxity and diminished strength, ankle range of motion (ROM), and static and dynamic postural control have …

Evaluation of Circumferential Ankle Pressure as an Ergonomic Intervention to Maintain Balance Perturbed by Localized Muscular Fatigue of the Ankle Joint
… specifically the effects of circumferential ankle pressure (CAP) and induced ankle fatigue on postural control. Fourteen young participants (seven males and seven females) performed fatiguing sub-maximal isotonic plantar flexion exercises on an isokinetic dynamometer, in the absence and …

Comparison of a Dynamic Ankle Orthosis to a Walking Boot for Preserving Ankle Joint Motion and Reducing Tibial Bone Load and Strain
… a walking boot for 3 – 12 weeks, which limits ankle motion and causes lower limb muscle atrophy. A Dynamic Ankle Orthosis (DAO) provided a distractive force that offloaded the ankle and retained sagittal ankle excursion during walking. It remains unclear how tibial loading is affected by a …

The effect of prophylactic ankle braces on postural sway
Ankle braces are commonly used in an attempt to decrease the risk of injury during sport. Despite the widespread use of ankle braces, their efficacy of use for uninjured ankles is questionable. The purpose of this study was to investigate the effects of a prophylactic ankle brace on postural sway, …

Kinematics at the ankle joint complex in rheumatoid arthritis
… the three-dimensional kinematics at the ankle joint complex in rheumatoid arthritis. Previous studies have identified the rearfoot as a common site for inflammatory activity in rheumatoid arthritis resulting in painful and disabling deformity for which there are no proven interventions. A …

Development of Methods for Characterizing Ankle Ligament Viscoelastic Properties
… for determining the viscoelastic properties of ankle ligaments. The tibiocalcaneal ligament was used for the method development and for the preliminary mechanical testing presented in this work. This document focuses primarily on the development of several novel approaches to: morphological …
