Effects of Dynamic, Static Stretch, and Proprioceptive Neuromuscular Facilitation on Running Velocity, Step Length, and Step Rate
… on collegiate female sprinters on the velocity, step length and step rate. Ten NCAA Division I female sprinters ranging in age from 18 to 22 participated in the study. A forty five meter sprint was performed with the section from thirty to forty meters digitally recorded and later analyzed for …

Transition between single and multiple stepping strategies in forward fall recovery
… Following a balance disturbance, one or more steps are often taken. Studies have shown that older adults are more likely than young adults to take multiple steps, and that number of steps is a predictor of fall risk. In order to better understand how a stepping strategy is chosen, we …

Changes in Gait Characteristics Following a Concussion
… GAITRite® walkway, where gait velocity, cadence, step length, step width, and double leg support times were calculated. The NONCs and CONCs walked the same number of days as their CONC match, until the CONC returned to participation. Results: Gait velocity showed significant group differences at …

The Effects of Age on Stress and The Biomechanics of Slips and Falls
… surfaces. Biomechanical parameters included: step length, required coefficient of friction (RCOF), slip distance, and heel contact velocity. Physiological parameters included: stress and anxiety. Overall, the results indicated that there were differences between older and younger adult's …

Effects Of Chemotherapy-Induced-Peripheral-Neuropathy On Spatiotemporal Gait Parameters And Fall Risk In Cancer Patients After The Completion Of Chemotherapy Drug Treatment
… the controls (147.79 cm/s,<em> SD</em> = 11.69). Step length was significantly shorter for CIPN (53.92 cm, <em>SD </em>= 23.55) when compared to the controls (77.15 cm, <em>SD</em> = 5.28). Lastly, CIPN participants had a significantly higher TUG Score (12.33 s, SD 6.25) compared to the controls …

Novel Technique for Gait Analysis Using Two Waist Mounted Gyroscopes
… applications such as indoor localization.</p> <p>Step detection and step length estimation are two basic and important gait analysis tasks. In fact, step detection is a prerequisite for the exploration of all other gait parameters. Researchers have proposed many methods for step detection, and …

The Impact of High-Cadence Cycling on Overground Running Performance in Recreational Runners
… the 800 m run. Total time, average cadence, step length, step time, velocity, and rate of perceived exertion were analyzed. Participants were also classified by running strategy groups using Length-Time Difference (LTD). Dependent-samples t-test revealed that 800 m time decreased …

Predictive balance control during backward walking and effects of a haptic input based intervention on predictive balance control during walking
… backward walking compared to forward walking. Step length and anteroposterior margin of stability were significantly reduced, and step width and mediolateral margin of stability were significantly increased during backward walking compared to forward walking. Backward walking was also …

The Effectiveness of a Physical Therapy Intervention for Children with Hypotonia and Flatfeet
… interventions. Gait parameters (velocity, step-length, single-limb support, and cadence) were assessed four times in a six-month period using the GAITRite™ system. <strong>Results:</strong> Significant differences pre/post testing (P<.05) were found in the arch index for the orthotic group …

Smart Technology for Telerehabilitation: A Smart Device Inertial-sensing Method for Gait Analysis
… the process. The third study presents a simple step length algorithm for straight-line walking and the fourth and final study addresses the accuracy of an iPod’s inertial-sensing capabilities, more specifically, the validity of an inertial-sensing method (integrated in an iPod) to obtain …

The Influence of the Initiation of a Graded Exercise Protocol on Dynamic Postural Stability Following a Concussion
… the fluctuation in gait characteristic between steps, is a sensitive measure of postural stability in populations with higher level gait disorders. Objective: The purpose of this study was to examine the influence of a progressive exertional return-to-play program on dynamic postural stability …

A Biomechanical Analysis of Male and Female Intermediate Hurdlers and Steeplechasers
… for research on hurdling events of different lengths. The intermediate hurdles (IH) and the steeplechase (SC) are two events where there are a number of differences in hurdling technique. This study compared the differences in hurdling technique between events (IH and SC) as well as the …

Trajectory Tracking of a Statically-stable Biped with Two Degrees of Freedom
… rotated the robot. Thus, the robot was able to step and turn on a flat surface. A control algorithm was developed to attempt trajectory tracking with the biped. Trajectories along a surface can be defined in terms of linear and angular velocities. In this research, it was assumed that a high …

Lagrangian Relaxation / Dual Approaches For Solving Large-Scale Linear Programming Problems
… using the conjugate subgradient concept. The step-length rules implemented in this regard are the Quadratic Fit Line Search Method and a new line search method called the Directional Derivative Line Search Method in which we start with a prescribed step-length and then ascertain whether to …

Effects of morphology, habitat and weather on the movement behaviour of range-expanding butterfly species
… species and individuals with longer move bouts (step length) cross habitat boundaries more frequently. Because step length is relatively easy to measure for butterflies, it could potentially be used as a general proxy of species dispersal capacity at a landscape level. I also found a higher …

Reaction Paths for Self-Organized Surface Roughening of Silicon-Germanium Alloys During Hydride Gas-Source Molecular Beam Epitaxy
… dominated by single- and multiple-atomic-height steps associated with the interfacial misfits. The surface steps are preferential H desorption sites, thus the increased total step length results in a decrease in thetaH on terraces which increases RSiGe and allows higher adatom ascending step …

The influence of a hip extension strengthening programme on gait performance in individuals following stroke
… was used to gather measures of gait velocity, step length and hip joint excursion. Statistically significant increases were found in the study group (n = 6) for the identified parameter of hip extensor strength after the intervention (p = 0.05), although this change could not necessarily be …
