The objective of this study was to compare the electromyographic (EMG) activity of vastus medialis obliquus (VMO), vastus lateralis longus (VLL) and vastus lateralis oblíquus (VLO) during wall slide squat isometric exercises at 45° (WS 45°) and at 60° (WS 60°) of knee flexion. Fifteen healthy control women and fifteen women with patellofemoral pain syndrome (PPS) participated in this study. The...

OBJECTIVE Patellar taping is frequently used to treat patellofemoral pain (PFP). This systematic review and meta-analysis (1) evaluates the efficacy of patellar taping for patients with PFP, (2) compares the efficacy of various taping techniques and (3) identifies potential biomechanical mechanisms of action. METHODS The MEDLINE, CINAHL, SPORTSDiscus, Web of Science and Google Scholar databas...

Background: The purpose of this study was to investigate the ratio of Electromyography (EM G) activities of the vastus medialis obliqus (VMO) and vastus lateralis (VL) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (OK C) and closed kinetic chain (CKC). Methods: The dominant knees of 44 healthy female subjects (mean age: 24.84 with range...

In this paper, we establish global $$W^{2,p}$$ estimates for solutions to the linearized Monge-Amp $$\grave{e}$$ re equation $$\begin{aligned} {\mathcal {L}}_{\phi }u:=\mathrm {tr}[\Phi D^2 u]=f \end{aligned}$$ under appropriate conditions on domain, measures, boundary data and f, $$\Phi :=(\mathrm {det}\,D^2\phi )(D^2\phi )^{-1}$$ is cofactor matrix of $$D^2\phi $$ . density measure $$g:=\math...

A nonlinear superposition operator $T_g$ related to a Borel measurable function $g:\ {\mathbb C}\to C}$ is defined via $T_g(f):=g\circ f$ for any complex-valued $f$ on ${\mathbb R^n}$. This article devoted investigating the mapping properties of new BMO type space recently introduced by Bourgain, Brezis and Mironescu [J. Eur. Math. Soc. (JEMS) 17 (2015), 2083-2101], as well its VMO CMO subspace...

We consider elliptic equations with operators $L=a^{ij}D_{ij}+b^{i}D_{i}-c$ $a$ being almost in VMO, $b\in L_{d}$ and $c\in L_{q}$, $c\geq 0$, $d>q\geq d/2$. prove the solvability of $Lu=f\in L_{p}$ bounded $C^{1,1}$-domains, $10$. Weak uniqueness martingale problem associated such is also obtained.
