introduction: low back pain (lbp) is the most common musculoskeletal disease. monochromatic infrared photo energy (mipe) and low level laser therapy (lllt) are light modalities used to reduce pain and increase blood flow. the aim of this study was to compare the effects of the mipe and lllt in reducing functional disability and pain as well as improving lumbar range of motion (rom) in patients ...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

educational psychology has approved that children will become accountable if we let them to make their own decisions, and they will be grown up self-confidence if we trust them. according to the same matters, the article no.12 of children’s rights international convention suggests providing opportunities for children to be able to make decisions whether by themselves or their representatives. t...

the effect of low intensity laser radiation in the treatment of acute and chronic pain is now established in many studies. trigeminal neuralgia is a pain passes through nerve’s branches and its trigger is located in skin or mucosa that could lead to pain with a trigger stimulus. the pain involved branches of trigeminal nerve that sometimes has patients to seek the treatment for several years. n...

background: neuropathic pain (np) is a serious suffering medical condition that frequently leads to disability and life style changes. although the exact mechanisms of np are still unknown, recently the role of reactive oxygen species (ros) reported as an important factor for np. apoptosis, increase of atp production and reduction of antioxidants are also the other factors influencing in np. th...
