OBJECTIVE To use a musculoskeletal model and simulation of running to examine: (1) the influence of two commonly prescribed treatments for patellofemoral pain (vastus medialis oblique strengthening and orthoses) and (2) the functional significance of timing differences between vastus medialis oblique and vastus lateralis on lateral patellofemoral joint loads. DESIGN A three-dimensional muscul...

Objective. To use a musculoskeletal model and simulation of running to examine: (1) the in ̄uence of two commonly prescribed treatments for patellofemoral pain (vastus medialis oblique strengthening and orthoses) and (2) the functional signi®cance of timing di€erences between vastus medialis oblique and vastus lateralis on lateral patellofemoral joint loads. Design. A three-dimensional musculosk...

Vastus medialis muscle of a 52-year-old male professional weight-lifter (master degree) was ruptured during training. After 3 days, he (HG.,D. Height: 179 cm, Weight: 98 kg) was admitted to sports medicine clinic with oedema, pain, and swelling on the medial side of his right knee (dominant side). After the physical examination and MRI assessment, nearly total vastus medialis rupture was detect...

[Purpose] This study evaluated the effective selective activation method of the vastus medialis oblique for knee joint stabilization in patients with patellofemoral pain syndrome. [Subjects and Methods] Fifteen healthy college students (9 males, 6 females); mean age, height, and weight: 22.2 years, 167.8 cm, and 61.4 kg, respectively) participated. The knee angle was held at 60°. Muscle activit...

The distribution of neurokinin A-like immunoreactive cell bodies and fibers in the diencephalon of the cat was studied using an indirect immunoperoxidase technique. A high or moderate density of immunoreactive neurons was observed in the nuclei habenularis lateralis, medialis dorsalis, parafascicularis, hypothalamus posterior, area hypothalamica dorsalis, hypothalamus lateralis, periventricular...

[Purpose] This study attempted to identify how genu varum or valgum affects the electromyographic activities of the vastus medialis, vastus lateralis, and rectus femoris during knee isometric contraction. [Subjects] Fifty-two healthy young adults were enrolled in this study. They were enrolled and classified into three groups by knee alignment conditions: the genu varum, genu valgum, and contro...

BACKGROUND The aim of this study was to investigate whether electromyographic manifestations of fatigue and exercise tolerance were related to stage of disease in men with a COPD diagnosis. METHODS Fourteen men with COPD with a diagnosis of mild to severe air flow obstruction were involved in 2 separate testing sessions. The first one consisted of a pulmonary function (FEV1 and FEV1/FVC) and ...

Subjects and methods The present pilot study is a case report on a single proband. Surface EMG (Noraxon) was recorded on one healthy subject during 3 resistive exercises using TheraBand (blue color). EMG activity during the agistic-excentric-exercises was analyzed on m. obliquus abdominis int., m. rectus abdominis, m. latissimus dorsi, m.erector spinae TH-L on the right and left side. The EMG a...
