The process of evaluating a built environment for accessibility is known as “accessibility assessment.” Determining accessibility is closely related to the problem of determining possible motions of a specific kinematic structure – given an environment and a mobile device, how much of the environment is accessible? Given these similarities, here the accessibility assessment process is reformula...

This paper describes a wearable system for the assessment of swim performance focusing on the description of the system and especially on the novel method for data transmission in water, and the algorithm used for extracting some parameters for the qualitative assessment of the performance. We placed a 3-axes Inertial Measurement Unit (IMU) on the athlete’s back in a specific swimsuit, which al...

Objectives: The aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how Total Knee Replacement (TKR) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. Methods: Two-dimensional kinematic gait pattern of 10 participants were collected before and after the TKR surgery,...

the momentum equation in the kinematic wave model is a power-law equation with two parameters. these parameters, which relate the discharge to the flow area, are commonly derived using manning’s equation. in general, the values of these parameters depend on the flow depth except for some special cross sections. in this paper, improved estimates of the kinematic wave parameters for circular chan...

Introduction we aimed to introduce a 6-universal-prismatic-spherical (UPS) parallel mechanism for the human jaw motion and theoretically evaluate its kinematic problem. We proposed a strategy to provide a fast and accurate solution to the kinematic problem. The proposed strategy could accelerate the process of solution-finding for the direct kinematic problem by reducing the number of required ...

This article shows that time derivatives of twists and wrenches are indeed screws, in contrast to many classical kinematicians’ believe. Furthermore, it is proven that the “centripetal screw,” as well as the momentum of a rigid body together with all its derivatives, are also screws, and that a rigid body’s dynamics can be geometrically expressed as a screw equation. The paper relies on a somew...

Validity of a clinical test can be defined as the extent to which the test actually assesses what it is intended to assess. In order to investigate the validity of manual physical assessment of the spine, it is therefore essential to establish what physical therapists intend to assess when they are applying these tests. The aims of this study were to (1) establish what manual physical therapist...

OBJECTIVE This pilot study investigates the use of telerehabilitation to improve upper limb performance in chronic stages of stroke recovery. DESIGN Intervention study with pre/post/one month follow-up tests. METHODS Seven adults with chronic stroke participated in the study. Tests consisted of lab-based clinical and kinematic assessments. Participants completed the Upper Limb Training and ...

Presented study gives findings of temporal-spatial kinematic gait analysis in 12 male adults, war trauma transtibial (TT) amputees fitted with prosthesis compared to 12 able-bodied persons. Results disclose asymmetries between the amputated, prosthetic and healthy legs of amputees, as well as between TT amputees and non-disabled persons. Amputees in comparison with able-bodied persons, generall...
