Purpose: To compare the regularity and symmetry of gait between a cohort of older adults with bilateral knee osteoarthritis (OA) and an age and sex-matched control group of older adults with healthy knees. Methods: Fifteen (8 females) older adults with knee OA (64.7 ± 6.7 years) and fifteen (8 females) pain-free controls (66.1 ± 10.0 years) completed a 9-min. walk at a self-selected, comfortabl...

BACKGROUND In this epidemiological study we described the characteristics of spatio-temporal gait parameters among a representative, population-based sample of 890 community-dwelling people aged 65 to 90 years. In addition, we investigated the associations between certain gait parameters and a history of falls in study participants. METHODS In descriptive analyses spatio-temporal gait paramet...

The gait of a multi-segment inchworm robot is a series of actuator actions that will change the shape of the robot to generate a net motion. In this article, we model the multisegment inchworm robot as a jinite state automaton. Gait generation is posed as a search problem on the graph described by the automaton with prescribed state transitions. The state transitions are defined based on the ki...

UNLABELLED The purpose of this study was to determine the differences in gait variability between patients with multiple sclerosis (MS) and healthy controls during walking at a self-selected pace. METHODS Kinematics were collected during three minutes of treadmill walking for 10 patients with MS and 10 healthy controls. The Coefficient of Variation (CoV), the Approximate Entropy (ApEn) and th...

Weighted sled towing is a common resisted sprint training technique even though relatively little is known about the effects that such practice has on sprint kinematics. The purpose of this study was to explore the effects of sled towing on acceleration sprint kinematics in field-sport athletes. Twenty men completed a series of sprints without resistance and with loads equating to 12.6 and 32.2...

PURPOSE To study immediate gait changes in persons with PD when walking with different assistive walking devices. METHODS Ten individuals with idiopathic PD participated in the study. Gait parameters were recorded while walking with a cane and a wheeled walker, and were compared to a free walk without a walking device. RESULTS Persons with PD walked with slower gait speed when using a cane ...

The purpose of the current study was to identify the biomechanical features of elite female baseball pitching. Kinematics and kinetics of eleven elite female baseball pitchers were reported and compared with eleven elite male pitchers. Results suggested that females share many similarities with males in pitching kinematics, with a few significant differences. Specifically, at the instant of str...

Myosin-5a is a molecular motor that transport cargoes and steps in symmetric hand-over-hand mechanism along actin, with both heads attached most of the time. By tracking 20 nm gold nanoparticles to single head myosin-5a heavy meromyosin-like construct, sub-nanometer precision via interferometric scattering (iSCAT) microscopy, analysis stride-sizes showed peaks corresponding 22, 24, 26, 28, 30, ...

Accurate estimation of walking distance plays an important role in numerous applications, such as gait analysis, sport training and particularly pedestrian localization in indoor environment [1]. One possible pervasive solution is to make use of motion dynamics contained in the inertial signals such as frequency, maximum/minimum amplitude, to aggregate individual stride. However, the main chall...
