OBJECTIVE To enable early prediction of strong traction force vacuum extraction. DESIGN Observational cohort. SETTING Karolinska University Hospital delivery ward, tertiary unit. POPULATION AND SAMPLE SIZE Term mid and low metal cup vacuum extraction deliveries June 2012-February 2015, n = 277. METHODS Traction forces during vacuum extraction were collected prospectively using an intell...

Traction-related problems are poorly described in the existing literature. The purpose of this prospective study was to describe traction-related problems and how patients perceive these problems. The study was a descriptive cohort study and data were collected from questionnaires and patient files. The questionnaire included questions on patients' perceptions of traction-related problems in th...

The objective of this study was to measure intradiscal pressure (IDP) changes in the lower cervical spine during a manual cervical distraction (MCD) procedure. Incisions were made anteriorly, and pressure transducers were inserted into each nucleus at lower cervical discs. Four skilled doctors of chiropractic (DCs) performed MCD procedure on nine specimens in prone position with contacts at C5 ...

BACKGROUND Preoperative skin traction is applied for many patients with hip fracture. However, the efficacy of this modality in pain relief is controversial. OBJECTIVES The aim of the current study was to investigate the effects of skin traction on pain in patients with intertrochanteric fractures. PATIENTS AND METHODS A total of 40 patients contributed in this randomized clinical trial. Pa...

The fastest way to decarbonise traction energy of a railway network is full electrification the network. However, can be costly and often delayed due complicated planning procedures. Often, it not financially viable electrify certain sections geographical challenges such as hillsides requirements raise or lower tracks. Intermittent provide reduce emissions on route without fully electrifying it...

Traction forces produced by moving fibroblasts have been observed as distortions in flexible substrata including wrinkling of thin, silicone rubber films. Traction forces generated by fibroblast lamellae were thought to represent the forces required to move the cell forwards. However, traction forces could not be detected with faster moving cell types such as leukocytes and growth cones (Harris...

I The forces required to detach the retina from the pigment epithelium and the subsequent structural changes were studied toith a device that produced retinal traction at different rates over localized, equatorial areas of freshly enucleated owl monkey and albino rabbit eyes. Sloio traction (0.2 to 0.8 mm. per minute) produced higher and larger retinal detachments and bigger tears in both types...

[Purpose] The aim of this study was to analyze the joint space width of the humeral head and glenoid fossa during traction under 2 grade conditions (grade 2/grade 3). [Subjects and Methods] The subjects were 20 healthy male adults who had not experienced any shoulder injury. Three radiographs were obtained with the subjects in the supine position (resting, grades 2 and 3). The glenohumeral join...

Traction forces increase after microtubule depolymerization; however, the signaling mechanisms underlying this, in particular the dependence upon myosin II, remain unclear. We investigated the mechanism of traction force increase after nocodazole-induced microtubule depolymerization by applying traction force microscopy to cells cultured on micropatterned polyacrylamide hydrogels to obtain samp...
