BACKGROUND AND OBJECTIVES Few studies have invasively assessed diastolic functional reserve and serial changes in left ventricular hemodynamics in euvolemic patients with exertional dyspnea. In this study, sequential changes in left ventricular end-diastolic pressure (LVEDP) to leg-raise exercise were measured invasively in patients with early heart failure with preserved ejection fraction (HFp...

STUDY DESIGN Cross-sectional, observational study. OBJECTIVES To explore how ankle position affects lower extremity neurodynamic testing. BACKGROUND Upper extremity limb movements that increase neural loading create a protective muscle action of the upper trapezius, resulting in shoulder girdle elevation during neurodynamic testing. A similar mechanism has been suggested in the lower extrem...

Purpose: This study aimed to investigate the electromyographic activities and balance of Vastus Medialis Obliquus (VMO) and Vastus Lateralis (VL) muscles during Straight Leg Raise (SLR) in individuals with and without Patellofemoral Pain Syndrome (PFPS). Methods: Through an analytical case-control study, 26 persons with PFPS and 26 healthy subjects were recruited by non-random and convenience ...

OBJECTIVE To identify the effect of a novel augmented core stabilization exercise technique on physical function, pain and core stability in patients with chronic low back pain. DESIGN A block randomized controlled trial with two groups. SETTING A sports rehabilitation clinic. PARTICIPANTS Forty patients with low back pain (20 experimental, mean (SD) age 50.35 (9.26) years and 20 control,...

Dynamic stability is an essential physical component for team sport athletes. Certain Functional Movement Screen (FMS) exercises (deep squat; left- and right-leg hurdle step; left- and right-leg in-line lunge [ILL]; left- and right-leg active straight-leg raise; and trunk stability push-up [TSPU]) have been suggested as providing an indication of dynamic stability. No research has investigated ...
