The purpose of this study was to determine if persons with patellofemoral pain (PFP) exhibit differences in patellofemoral joint reaction forces (PFJRFs) during functional activities. Forty females (20 PFP, 20 controls) underwent two phases of data collection: (1) magnetic resonance imaging (MRI) and (2) biomechanical analysis during walking, running, stair ascent, and stair descent. A previous...

As the field of artificial intelligence becomes increasingly advanced and integrated, it is time to revisit the half-century old “AIDream,” where intelligent robotic agents were envisioned to interact with the general human population. To this end, the Stanford Artificial Intelligence Robot (STAIR) project aims to introduce robots into home and office environments, where they will facilitate an...

BACKGROUND Osteoarthritis (OA) of the knee is a common form of arthritis, and affects quality of life. We investigated factors associated with functional limitation in stair climbing among female Japanese patients with knee OA. As weight is a known risk factor for knee OA, we focused on body weight at 40 years of age, and examined the association with present weight, past weight, and weight cha...

OBJECTIVE The aim of this study was to compare gaze behaviour during stair and ramp walking between patients with chronic peripheral vestibular hypofunction and healthy human subjects. METHODS Twenty four (24) patients with chronic peripheral vestibular hypofunction (14 unilateral and 10 bilateral) and 24 healthy subjects performed stair and ramp up and down walks at self-selected speed. The ...

Background. Stair climbing is often performed by people in daily life and requires considerable energy muscle effort. This task has been widely described the literature, but role of knee joint ligaments not sufficiently investigated. could be relevant for planning ligament reconstruction surgery, providing suggestions to subjects with partial injuries, identifying compensatory strategies reduci...

EEcient geometric algorithms are given for optimization problems arising in layered manufacturing , where a 3D object is built by slicing its CAD model into layers and manufacturing the layers successively. The problems considered include minimizing the stair-step error on the surfaces of the manufactured object under various formulations, minimizing the volume of the so-called support structur...

In this report I present the results of my work this fall, with the tremendous help and support of Olga Russakovsky, on the STAIR Person Following project. There are, roughly speaking, three components of this project: the vision system; the navigation system; and the recovery system. I describe first the use of the Phasespace Motion Capture System to accomplish the vision task and a simple mod...

One of the basic problems of user on manual wheelchair is overcoming architectural barriers (kerbs, stairs etc.) on its way. Even though many research studies have been reported in different fields to increase the independence of wheelchair users, the question of overcoming obstacles by a wheelchair always remains as topic of discussion for many researchers. In this paper, the author has propos...

background: the ultimate goal of diabetes control is hba 1c improvement. the purpose of this study was to assess the effect of empowerment model on hba 1c among adolescents with type 1 diabetes. methods: the present semi-experimental study was carried out on some 47 diabetic adolescents in order to investigate the effect of an educational program based on the empowerment model on hba 1c among a...
