background: patellofemoral pain (pfp) is a common affliction and complex clinical entity. deficit in neuromotor control of the core may be a remote contributing factor to the development of pfps. comparative evaluation of core and extensor mechanism muscle activation patterns between healthy group and patients involved by patellofemoral pain syndrome(pfps) in a stair stepping task is the aim of...

BACKGROUND Performance tests are important to characterize patient disabilities and functional changes. The Osteoarthritis Research Society International and others recommend the 30-second Chair Stand Test and Stair Climb Test, among others, as core tests that capture two distinct types of disability during activities of daily living. However, these two tests are limited by current protocols of...

background: the goal was to upgrade and/or uprate the traditional non-contact array by producing few modifications in the configuration of this model in order to maximize light receiving of water from the uv lamp and a better disinfection.  methods: an innovative non-contact model was made with a design based on irradiation of water, which was flowing as two thin waterfalls around a uv lamp in ...

Total knee arthroplasty (TKA) is a generally successful surgical procedure to treat end-stage knee osteoarthritis; however, suboptimal outcomes, including difficulty stair climbing, do occur [1]. Clinicians use the stair climbing test (SCT) to track functional status, where a patient ascends and descends a flight of stairs as fast as possible and a faster time suggests better function and incre...

Climbing stairs is an incidental physical activity that people can incorporate within daily life. Observational studies have shown that posters at the point of choice between stairs and escalators can increase stair use. As the greatest public health benefits can be gained from encouraging the least active to exercise more, stair and escalator users were interviewed to assess whether poster pro...

BACKGROUND Transtibial amputees encounter stairs and steps during their daily activities. The excessive pressure between residual limb/socket may reduce the walking capability of transtibial prosthetic users during ascent and descent on stairs. The purposes of the research were to evaluate the interface pressure between Dermo (shuttle lock) and Seal-In X5 (prosthetic valve) interface systems du...

The purpose of this study was to describe an imaging based, subject specific model that was developed to quantify patellofemoral joint reaction forces (PFJRF's). The secondary purpose was to test the model in a group of healthy individuals while performing various functional tasks. Twenty healthy subjects (10 males, 10 females) were recruited. All participants underwent two phases of data colle...

BACKGROUND Previous Stroke Therapy Academic Industry Roundtable (STAIR) meetings focused on preclinical evidence of drug efficacy and enhancing acute stroke trial design and performance. A fourth (STAIR-IV) was held to discuss relevant issues related to acute stroke drug development and regulatory approval. SUMMARY OF REVIEW The STAIR-IV meeting had 3 main focus areas. The first topic was nov...
