Aim: To compare the effects of closed kinetic chain and open exercises in strengthening vastus medialis obliqus subjects with Patello-femoral pain syndrome. Methods: The study was a randomized controlled trial. It conducted to impact strengthen Vastus PFPS patients. For this purpose, 36 patients both males females age 20-40 years having were allocated randomly two experimental (group A group B)...

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: 20-...

[Purpose] This study investigated the effects of the slow speed-targeting squat exercise on the vastus medialis oblique/vastus lateralis ratio. [Subjects] Ten asymptomatic men were recruited. [Methods] The EMG activities of the vastus medialis oblique and vastus lateralis muscles were recorded using surface electrodes. The subject performed the squat exercise under 3 different conditions. [Resu...

abstract background and aim: lack of balance in pattern and activity of quadriceps and hamstring muscles increases the risk of anterior cruciate ligament injury (acl). the purpose of the present study was to investigate the changes in pattern and activity of vastus medialis and semitendinosusmuscles in landing from different heights and to understand if these changes will increase the risk of a...

[Purpose] The purpose of this study was to examine the vastus medialis oblique to vastus lateralis ratio in two pelvic tilt positions while performing the sit-to-stand task. [Subjects and Methods] Activation of the vastus medialis oblique and the vastus lateralis muscles of 46 healthy subjects (25 males, 21 females) were recorded by surface electromyography during the STS task with anterior pel...

(1) Background: this study aimed to determine if there are differences in quadriceps and hamstring muscle activation professional male female soccer players. (2) Methods: was recorded by surface electromyography 27 players (19 8 female). The performed the Bulgarian squat lunge exercises. Vastus medialis, vastus lateralis, rectus femoris, semitendinosus, biceps femoris were muscles analyzed. (3)...

The distribution of parvalbumin-immunoreactive cell bodies and fibers in the cat diencephalon has been analyzed by using the avidin-biotin immunoperoxidase technique. The thalamus showed a higher density of immunoreactive cell bodies than the hypothalamus. A high or moderate density of perikarya and a high density of fibers containing parvalbumin was observed in the nuclei lateralis posterior, ...

This study aims to examine the effect of McConnell taping to patients with patellofemoral pain syndrome on the change of the muscle activity of vastus medialis and vastus lateralis during squatting. The total numbers of participants are 16 patients with pain in their knee. There are three different experiments: no-taping, placebo taping, and McConnell taping. As a result, both the muscle activi...
