Excellent reliability of toe strength measurements in children aged ten to twelve years achieved with a novel fixed dynamometer Gait Posture (IF 2.349) Pub Date : 2021-01-20 Shayan Quinlan; Peter Sinclair; Adrienne Hunt; Alycia Fong Yan
Background Stronger toe flexor muscles improve performance outcomes in children, including balance, sprinting, jumping and side stepping. Toe flexor strength (TFS) is recommended as part of the clinical assessment of foot function in children. Fixed dynamometry, rather than handheld, is the gold standard of measurement; however, it can be prohibitively costly. No fixed dynamometer reliability studies

Reliability testing of the heel marker in three-dimensional gait analysis Gait Posture (IF 2.349) Pub Date : 2021-01-13 Jennifer McCahill; Wouter Schallig; Julie Stebbins; Robin Prescott; Tim Theologis; Jaap Harlaar
Introduction In three-dimensional gait analysis, anatomical axes are defined by and therefore sensitive to marker placement. Previous analysis of the Oxford Foot Model (OFM) has suggested that the axes of the hindfoot are most sensitive to marker placement on the posterior aspect of the heel. Since other multi-segment foot models also use a similar marker, it is important to find methods to place this

‘Haste makes waste’: the tradeoff between walking speed and target-stepping accuracy Gait Posture (IF 2.349) Pub Date : 2021-01-09 Melvyn Roerdink; Daphne J. Geerse; Lieke Peper
Background When environmental conditions require accurate foot placement during walking (e.g., on a rough path), we typically walk slower to avoid tripping, slipping or stumbling. Likewise, hurrying too much is a common situational circumstance of walking-related falls. This suggests a tradeoff between walking speed and stepping accuracy in situations that demand precise foot placement. Research question

Background. Several articular, muscular and neurological diseases generate mobility and coordination loss in the shoulder and pelvic girdles. Joint mobilization contributes to improving girdles dissociation, but current mobilization techniques aren’t always successful. Research question. To determine the optimal running frequency of a trunk and pelvis mobilization technique, in supine position, that

The effect of cognitive loading on the lower extremity movement coordination variability in patients with anterior cruciate ligament reconstruction Gait Posture (IF 2.349) Pub Date : 2020-11-28 Huijuan Shi; Shuang Ren; Xin Miao; Haocheng Zhang; Yuanyuan Yu; Xiaoqing Hu; Hongshi Huang; Yingfang Ao
Background The altered coordination variability was related to anterior cruciate ligament (ACL) re-injury after ACL reconstruction (ACL-R). As motor performance is affected by the cognitive loading, understanding the interaction of cognition and coordination variability is crucial for addressing secondary injury prevention and restoring function in rehabilitation programs. Research Question To investigate

Digital bathroom scales with open source software provide valid dynamic ground reaction force data for assessment and biofeedback Gait Posture (IF 2.349) Pub Date : 2020-10-23 Ross A. Clark; Benjamin F. Mentiplay; Hong Han Tan; Louise Bechard; Emma Hough; Yong-Hao Pua
Background Measuring dynamic vertical ground reaction force allows for assessment of important clinical and physical capacity factors such as weight bearing asymmetry, force distribution, and rate of force development. However, current technologies for accurately assessing ground reaction force are typically expensive. Research Question The aim of this study was to examine the validity and reliability

Focusing on functional knee parameter determination to develop a better clinical gait analysis protocol Gait Posture (IF 2.349) Pub Date : 2020-11-05 J. Leboucher; F. Salami; O. Öztürk; D.W.W. Heitzmann; M. Götze; Th. Dreher; S.I. Wolf
Background Attempts to improve protocol standards of marker-based clinical gait analysis (CGA) have been one of the main focuses of research to enhance robustness and reliability outcomes since the 1990s. Determining joint centres and axes constitutes an important aspect of those protocols. Although the hip joint is more prominent in such studies, knee joint center (KJC) and axis (KJA) directly affect
