BACKGROUND AND OBJECTIVE Cervical radiculopathy is a common neuro-musculo-skeletal disorder causing pain and disability. Traction is part of the evidence based manual physical therapy management due to its mechanical nature, type of traction and parameters related to its applicability and are still to be explored more through research. Our objective was to determine the Effects of Mechanical ve...

One hundred and sixty-seven patients with adolescent idiopathic scoliosis were allocated prospectively to one of three different groups for correction before undergoing posterior spinal fusion and Harrington instrumentation, In group 1 single curves were corrected by a Risser turnbuckle plaster jacket and double curves by halo-pelvic traction. In Group 2 patients performed Cotrel dynamic tracti...

BACKGROUND Proximal femur fractures are one of the most common injuries necessitating operative treatment. The aim of this prospective study was to evaluate and compare the possible effects of the preoperative application of a skin traction device, with or without weights, on pain relief in patients with acute proximal femur fracture. MATERIALS AND METHODS This study included 108 pre-operativ...

Migration of a fibroblast along a collagen fiber can be regarded as cell locomotion in one-dimension (1D). In this process, a cell protrudes forward, forms a new adhesion, produces traction forces, and releases its rear adhesion in order to advance itself along a path. However, how a cell coordinates its adhesion formation, traction forces, and rear release in 1D migration is unclear. Here, we ...

Ischaemic diabetic retinopathy may be complicated by multiple outgrowths of fibrovascular tissue on to the retinal surface within the most cortical part of the vitreous gel, typically along the major vascular arcades and nasal to the optic disc. Tangential traction, exerted by contraction of the coalescent epiretinal membranes, results in distortion, folding, and detachment of the underlying re...

It has been suggested that myosin II exerts traction forces at the posterior ends and retracting pseudopodia of migrating cells, but there is no direct evidence. Here, using a combination of total internal reflection fluorescence (TIRF) microscopy and force microscopy with a high spatial resolution of approximately 400 nm, we simultaneously recorded GFP-myosin II dynamics and traction forces un...

Interactions between cells and the surrounding matrix are critical to the development and engineering of tissues. We have investigated the role of cell-derived traction forces in the assembly of extracellular matrix using what we believe is a novel assay that allows for simultaneous measurement of traction forces and fibronectin fibril growth at discrete cell-matrix attachment sites. NIH3T3 cel...

OBJECTIVE: To determine frequency of improvement in anatomical alignment of cervical spine with skeletal traction in patients with cervical spine injury. METHODOLOGY: This retrospective observational study was conducted at neurosurgery department, Lady Reading Hospital, Peshawar. The medical record of all cases from December 2010 to November 2011, in which cervical traction was applied for cerv...

In order to investigate the effect of traction of the vasculature on induction or acceleration of neovascularization, the chorioallantoic membranes (CAMs) of the developing chick embryo were placed under tension with 10-0 nylon sutures and subsequently examined histologically. In the initial phase of the study, CAMs from 6- to 8-day-old chick embryos were placed under traction and sampled seria...

The most distinct advantage of electric vehicle is in its quick and precise torque generation. We propose two novel traction control techniques of electric vehicle, i.e., the model following control and the optimal slip ratio control. Their effectiveness is demonstrated by using the test vehicle "UOT Electric March".
