Differences in locomotor biomechanics between walking and running provide fundamental information about human ambulation. Joint mechanical impedance is a biomechanical property that governs the body's instantaneous response to disturbances, and is important for stability and energy transfer. Ankle impedance has been characterized during walking, but little is known about how humans alter joint impedance during running. The purpose of this study was to estimate ankle impedance during the stance phase of running, and compare to previously reported estimates during walking.

An objective understanding of human foot and ankle function can drive innovations of bio-inspired wearable devices. Specifically, knowledge regarding how mechanical force and work are produced within ...
Individuals with lateral ankle sprain and chronic ankle instability have impaired postural control and altered motor strategies during walking. However, little is known regarding foot mechanics during...
Previous studies showed functional ankle instability (FAI) patients have morphological ligamentous abnormality, despite having no apparent joint laxity.
Conventional knee-ankle-foot orthoses (KAFOs) are generally prescribed for children with lower limb muscle weakness and joint instabilities. The main function of KAFOs is to provide stability during g...
Quantitative measurement of the mechanical deficit in chronic ankle instability (CAI) is difficult. Therefore, the distinction between functional (FAI) and mechanical ankle instability (MAI) as well a...
The proposed research study aims to investigate whether a gait modification training program to decrease peak braking forces during the stance phase of running will result in a reduction i...
Prospective, international, multi-center, open-labeled, randomized, controlled cross-over trial to evaluate effectiveness and benefits in patients with lower limb impairment in activities ...
A convenience sample of 20 participants, 18 years or older healthy individuals were recruited. Participants were excluded if they report being pregnant or being treated for a musculoskelet...
Inter-individual variability in energetic cost of running may be partly explained by lower limbs mechanical characteristics. The transposition of muscle mechanical model with two component...
Running is a natural part of human locomotion and humans have been running for million of years. In modern society, running has become a popular way of exercise and is undertaken by many p...
Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance).
A type of impedance plethysmography in which bioelectrical impedance is measured between electrodes positioned around the neck and around the lower thorax. It is used principally to calculate stroke volume and cardiac volume, but it is also related to myocardial contractility, thoracic fluid content, and circulation to the extremities.
Harm or hurt to the ankle or ankle joint usually inflicted by an external source.
Recording changes in electrical impedance between electrodes placed on opposite sides of a part of the body, as a measure of volume changes in the path of the current. (Stedman, 25th ed)
The interval between two successive CELL DIVISIONS during which the CHROMOSOMES are not individually distinguishable. It is composed of the G phases (G1 PHASE; G0 PHASE; G2 PHASE) and S PHASE (when DNA replication occurs).
