Stride-to-stride variability is altered during backward walking in anterior cruciate ligament deficient patients.
Franceska Zampeli,Constantina Moraiti Moraiti,Sofia A. Xergia,Vasilios Tsiaras,Nicholas Stergiou,Nicholas Stergiou,Anastasios D. Georgoulis +6 more
TL;DR: Anterior cruciate ligament (ACL) deficiency leads to loss of optimal variability regardless of the walking direction as compared to healthy individuals, which could imply diminished functional responsiveness to the environmental demands for both knees of ACL deficient patients which could result in the knees being more susceptible to injury.
Journal ArticleDOI
Expressing the joint moments of drop jumps and sidestep cutting in different reference frames : does it matter?
TL;DR: The magnitude and the resulting ranking of hip and knee joint moments expressed in the laboratory coordinate system, the local system of the distal segment and projected or decomposed to the Joint Coordinate System (JCS) axes are compared.
Journal ArticleDOI
Hamstring tendon anterior cruciate ligament reconstruction: does gracilis tendon harvest matter?
TL;DR: Harvesting the gracilis in addition to semitendinosus does not appear to affect either the outcome or graft-related morbidity after hamstring ACL reconstruction.

TL;DR: The study demonstrated good concurrent validity for the wi-GAT system, which has the potential to be a useful assessment tool for clinicians.
Journal ArticleDOI
Determination of the optimal locations of surface-mounted markers on the tibial segment
TL;DR: The results showed a subset of four markers with inter-marker pair distances on the tibia have less than 1.6 mm variation (standard deviation (S.D.)) during walking, which is optimal for defining the tibial segment.

Measurement of lower extremity kinematics during level walking
TL;DR: The relatively small number of body surface markers used in the VICON system render it easy to implement for use in routine clinical gait evaluations and should be a useful reference for describing and comparing pathologic gait patterns.

Principles of dynamics
TL;DR: In this article, the Lagrange Equations are used to model the dynamics of a rigid body and a system of parts of a particle system with respect to the velocity of a single particle.
Journal ArticleDOI
Justification of triaxial goniometer for the measurement of joint rotation.
TL;DR: Considering all factors in joint functional evaluation, the modified triaxial goniometer is a useful and effective method to provide simple real time three-dimensional angular motion measurements.
Journal ArticleDOI
The anthropometry of the manual work space for the seated subject
TL;DR: This paper is an exploration of the space-geometry of hand motions as they relate to young men in the seated posture primarily in functional anthropometry, but the information derived should have practical use in improving the design of work areas.

Walking patterns of men with parkinsonism.
TL;DR: Interrupted-light photography was used to record the simultaneous displacement patterns of multiple body segments of 44 patients with parkinsonism during free-speed and fast walking to quantitatively characterize their gait peculiarities.
