Atypical Pronation of the Sub-Talar Joint: Its Implications on the Lower Limb.
Název: Atypická pronace subtalárního kloubu: dopad na spodní končetinu Pozadi Atypická pronace subtalárního kloubu, nebo-li přílišná pronace, což je častěji používaný výraz, je aktuální podtéma v rámci problémů věnujícím se biomechanice nohou a dolních končetin. Typická pronace je troj planární …

An evaluation of a supermarket bagging task using a wrist motion monitor
… for flexion-extension, radial-ulnar, and pronation-supination deviations. The dependent variables were handle type and object location. A wrist motion monitor designed at Ohio State University was used to quantify wrist posture and movement. Objects with finger-thumb handle couplings …

Lower leg and foot contributions to turnout in pre-professional female dancers: A clinical and kinematic analysis
… external tibiofemoral rotation (TFR) and foot pronation. Yet knowledge of these compensatory mechanisms is based on biomechanical theories and clinical observations rather than quantitative clinical assessments or 3D motion analysis. The principal aim of this research was to investigate the …

An investigation into the variable biomechanical responses to antipronation foot orthoses
Antipronation foot orthosis are commonly used by health care professionals to treat a variety of lower limb conditions thought to be caused by excessive foot pronation. However, despite their widespread use, laboratory based research indicates that antipronation foot orthosis cause variable joint …

Initial wrist posture during typing as a function of keyboard height and slope
… flexion-extension, radial-ulnar deviation, and pronation-supination for 24 righthanded subjects at 25 combinations of keyboard height and slope. Keyboard heights tested were: -10, -5, 0, 5, and 10 cm from elbow height, and keyboard slopes tested were: -45, -22, 0, 22, and 45 degrees from …

Estimation of distal arm joint angles from EMG and shoulder orientation for transhumeral prostheses
… of both elbow flexion/extension and forearm pronation/supination during arm movements. In this thesis, we quantify the extent to which shoulder orientation, upper-arm EMG, and forearm EMG are predictors of distal arm joint angles for subjects without impairment, as well as subjects with a …

The design and development of an electromechanical adaptation for a Novel 3D printed functional hand prosthesis
… find useful for completing ADLs such as wrist pronation and supination. The aim of this study was thus to design an electromechanical hand prosthesis that meets the functional and grasping requirements of prosthesis users. To this end, the Self-Actuated Tenim Hand (SATH), a functional …

Influence of motion profile on estimating anatomical elbow joint axes using inertial measurement units
… estimation and high accuracy estimation of the pronation/supination elbow axis. Further, high off-axis motion and low on-axis motion yielded imprecise axis estimation and inaccurate estimation of both the flexion/extension and pronation/supination elbow axes. A comparative study of different …

Zusammenhänge zwischen subjektiver Wahrnehmung und physikalisch messbaren Parametern von Dämpfungsmechanismen beim Laufvorgang
… sich auf die Teilbereiche aktive Dämpfung (Pronation etc.), Stabilität, Paßform, Bodenreaktionskräfte und Sohlenparameter. Paßform und Stabilität erwiesen sich teilweise als bewußt wahrnehmbar. Geringes Pronationsverhalten und ein flacher Leisten zeigten hier einen positiven Einfluß auf das …

Visual Computing and AI Technologies to Analyse Movement Disorders Associated with Parkinson’s Disease for Diagnostic Purposes
… including finger tapping, opening-closing and pronation-supination hand movements. Clinicians reviewed movement performance in each video and assigned corresponding MDS-UPDRS scores, providing motor symptom severity class labels for classification and correlation analysis. A real-time computer …

An Eccentric Intervention of the Flexor-Pronator Mass To Impact Overhead Throwing Distance and Velocity
… specific muscle group is responsible for primary pronation and flexion at the elbow joint, while also reducing valgus stress from compromising the ulnar collateral ligament. </p> <p>Twenty-three participants were put through a short throwing progression that was focused on their velocity and …

Characterization and control of a robot for wrist rehabilitation
… governed by a differential gear mechanism, while pronation and supination of the forearm are actuated by a curved slider attached to the rest of the mechanism. Through the characterization, the device was found to exhibit some unwanted behavior, largely attributable to the nonlinearities inherent …

Simultaneous Multi-Joint Myoelectric Control of Transradial Prostheses
… that would allow multiple joints (forearm pronation-supination, wrist flexion-extension, and hand opening-closing) of a transradial prosthesis to be controlled in a highly coordinated fashion. We demonstrated than a time-delayed artificial neural network controller could be trained to …

The impact of drug-induced dyskinesias on rapid alternating movements in patients with Parkinson's disease
… subjects. Whole-body magnitude (WBM) and fast pronation-supination at the wrist were recorded using 6- degrees of freedom magnetic motion tracker and forearm rotational sensors, respectively. Subjects were asked to pronate-supinate their dominant hand for 10s. Pre- and postmeasures were taken …
