this study was a clinical trial performed using consecutive method of samplind for 3.5 years in the physiotherapy clinic of Rafsanjan university of medocal sciences.the purpose of this research was to evaluate the effect of the ultrasound along with muscle stretch with ultrasound and muscle stretch along in the treatment of the myofascial trigger points(MTPs).one haundred and twenty patients wh...

1. Stretch-induced muscle injury results in the damage that causes reduced force and increased membrane permeability. This muscle damage is caused, in part, by ionic entry through stretch-activated channels and blocking these channels with Gd3+ or streptomycin reduces the force deficit associated with damage. 2. Dystrophin-deficient muscles are more susceptible to stretch-induced muscle injury ...

BACKGROUND Children with spastic cerebral palsy experience increased muscle stiffness and reduced muscle length, which may prevent elongation of the muscle during stretch. Stretching performed either by the clinician, or children themselves is used as a treatment modality to increase/maintain joint range of motion. It is not clear whether the associated increases in muscle-tendon unit length ar...

background: mesenchymal stem cells (mscs) can be expanded and differentiated into many mature cell types including smooth muscle cells (smcs). in addition to growth factor, cyclic stretch contributes to differentiation of stem cells. mechanical stimuli are critical to morphological changes, development, regeneration, differentiation and pathology of mesenchymal tissues. the aim of this study is...

Discoidin domain receptor 2 (DDR2) plays potential roles in the regulation of collagen turnover mediated by smooth muscle cells in atherosclerosis. How mechanical stretch affects the regulation of DDR2 in smooth muscle cells is not fully understood. We sought to investigate the cellular and molecular mechanisms of regulation of DDR2 by cyclic stretch in smooth muscle cells. Rat vascular smooth ...

Correspondence to Kenneth B. Campbell: [email protected] Stretch activation is an intrinsic length-sensing mechanism that allows muscle to function with an autonomous regulation that reduces reliance on extrinsic regulatory systems. This autonomous regulation is most dramatic in asynchronous insect fl ight muscle and gives rise to wing beat frequencies that exceed the frequency capacity o...

Abnormal mechanical forces can trigger aberrant proliferation of endothelial and smooth muscle cells, as observed in the progression of vascular diseases such as atherosclerosis. It has been previously shown that cells can sense physical forces such as stretch through adhesions to the extracellular matrix. Here, we set out to examine whether cell-cell adhesions are also involved in transducing ...
