One of the most common forms of chronic pain is back pain. Until now, nothing has been known about the influence of visualizing one's own back on pain perception at this site. We tested 18 patients with chronic back pain and 18 healthy controls, by implementing online video feedback of the back during painful pressure and subcutaneous electrical stimuli over the trapezius muscle. Pain threshold...
In this study, the supersonic and choked subsonic flows through micro/nano channels are investigated using direct simulation Monte Carlo (DSMC) method. The supersonic case is simulated at different Knudsen numbers covering slip to transition flow regimes, while the effects of inlet Mach and back pressure are studied in details. The inlet/outlet pressure boundary conditions are suitably implemen...
BACKGROUND Tension and stress are among the factors that lead to hypertension. In most individuals, behavioral strategies, such as relaxation and massage, are effective in controlling the individuals' response to stress, thus reducing hypertension. METHODS This non-blind clinical trial was conducted on 90 patients with primary hypertension. The patients were randomly divided into a control an...
DURING an investigation into the cause and treatment of eclampsia, it was noticed that there was an appreciable difference between the blood pressure when the patient was on the back and that taken when on the side. When this had been noticed several times, a routine was developed in order to determine whether this difference was constant at all times, and with different patients. At the end of...
OBJECTIVE To evaluate the effect of hyaluronidase in patients with failed back surgery syndrome (FBSS) treated with interlaminar lumbar epidural injection (ILEI). METHOD Sixty patients suffering from severe low back pain and sciatica were randomly allocated into three groups. Group T received ILEI with 2 ml triamcinolone 40 mg/ml and 5 ml bupivacaine 0.25%. Group H received ILEI with 1500 IU ...
We present a design for a miniature self-priming peristaltic pump actuated with a single linear actuator, and which can be manufactured using conventional materials and methods. The pump is tolerant of bubbles and particles and can pump liquids, foams, and gases. We explore designs actuated by a motor (in depth) and a shape memory alloy (briefly); and briefly present a manually actuated version...
â performance and capacity of sulfur recovery unit (sru) are greatly affected by the h2s:co2 ratio of the acid gas stream. the acid gases in iran contain around 35 mol% h2s and 60 mol% co2. this low concentration of h2s calls for more complex sulfur plant, larger equipments, and higher costs. acid gas enrichment processes (age) is run to upgrade low quality acid gas collected from gas treating...
We developed a mobility detection system to analyze pressure changes over time during side-turns in 29 healthy volunteers (17 males and 12 females) with a mean age of 46.1 ± 19.64 years (ranging from 23 to 86 years) in order to determine the effect of gender, age, and BMI on performance during bed postural change. Center of gravity (COG) location, peak pressure of counteraction, and time to rea...
introduction: work pressure and excessive workload can jeopardize and impair the people’s health. one of these impairments is musculoskeletal disorders. among these disorders, low back pain is the most common and most costly problem. the purpose of this study was to investigate the relationship between workload and prevalence of low back pain in assembly line workers of a car manufacturing fact...
