BACKGROUND One of the rationales behind using strength training in the treatment of adolescents with Patellofemoral Pain (PFP) is that reduced strength of the lower extremity is a risk factor for PFP and a common deficit. This rationale is based on research conducted on adolescents >15 years of age but has never been investigated among young adolescents with PFP. OBJECTIVES To compare isometr...

abstractbackgroundentity. it is hypothesized to result from abnormal patellar tracking caused by altered motorcontrol. deficit in neuromotor control of the core may be a remote contributing factor to thedevelopment of pfp. application of reliable emg measures would be helpful to handle thistheory. therefore, the purpose of this study was to determine the test-retest reliability of thecore and v...

PURPOSE OF REVIEW To provide a state-of-the-science review of the literature on secondary prevention of HIV infection or 'prevention for positives' (PfP) interventions. RECENT FINDINGS Early work on PfP focused on understanding the dynamics of risky behavior among People Living with HIV/AIDS (PLWH) and on designing, implementing, and evaluating a limited number of interventions to promote saf...

PURPOSE Presentation of four patients with bilateral peripheral facial nerve palsy as a clinical manifestation of neuroborreliosis in children--diagnostic, treatment and prognosis. MATERIAL AND METHODS In 2002-2004 in The Chair and Department of Developmental Neurology, 24 children from the Wielkopolska region were admitted with diagnosis of borreliosis. Among all the children with borreliosi...

A seven fold increase in the rate of respiratory O2 uptake was observed 24 h after slicing of potato tuber disks. The maximum activity of pyrophosphate:fructose-6-phosphate phosphotransferase (PFP) was 5-7 times greater than that of ATP-dependent phosphofructokinase (PFK) in fresh or aged potato slices. Thus, PFP may participate in glycolysis which supplies respiratory substrate in potato tuber...

Genomic clones encompassing the entire coding region of the mouse lymphocyte pore-forming protein gene (Pfp) have been isolated and used to determine its intron-exon organization. In contrast to C9, Pfp has a simple structure, consisting of only three exons (two of which encode polypeptide), a large 5' intron, and a single, smaller intron that is situated approximately one-third of the way thro...

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...

Compensation systems such as individualized pay for performance (I-PFP) schemes for employees represent an important approach to aligning employer-employee interests. However, the adoption of I-PFP is much less common in many countries than in the USA. Employing a multi-level analysis of over 4,000 firms in 26 countries, we explore determinants of its adoption. At the country level we distingui...

OBJECTIVE The purpose of this study was to investigate the role of hip muscles in patellofemoral pain (PFP), specifically by investigating neuromotor control, strength and range of motion of the hip muscles. DESIGN Cross-sectional. SETTING University laboratory. PATIENTS Ten participants diagnosed with PFP and 27 asymptomatic controls were recruited, using standard inclusion and exclusion...

Objectives Current structural associations of patellofemoral pain (PFP) are based on 2D imaging methodology with inherent measurement uncertainty due to positioning and rotation. This study employed novel technology to create 3D measures of commonly described patellofemoral joint imaging features and compared these features in people with and without PFP in a large cohort. Methods We compared...
