Trunk muscle activity during pressure feedback monitoring among individuals with and without chronic low Back pain.

Background: Pressure biofeedback unit (PBU) is a widely used non-invasive device to assist core muscle training by providing pressure feedback. The aim this study was to compare the muscle activities of transverse abdominis (TA) and multifidus (MF) at different target pressures (50, 60 and 70 mmHg) of PBU between individuals with and without cLBP.

Methods: Twenty-two patients with chronic LBP (cLBP) and 24 age matched healthy individuals were recruited.

Effects of Different Sling Settings on Electromyographic Activities of Selected Trunk Muscles: A Preliminary Research.

Introduction: The supine and prone sling exercise may facilitate activation of the local trunk muscles. Does the side-lying sling exercise activate trunk muscles more easily than the supine and prone training with sling settings? Clinical work has shown that the side-lying sling exercise could reduce pain in patients with unilateral low back pain (LBP), but the mechanism behind it is unclear. The fundamental purpose of this preliminary study was to examine the electromyography (EMG) characteristics of trunk muscles during different sling lumbar settings on sixteen healthy adults.

[Survey on behaviors of health in poverty area from the mid-west four provinces of China].

Objective: To understand ways of life among poverty-stricken farmers from western areas of China.

Methods: Questionnaires on ways of life were designed, using cluster random sampling method to study 5516 rural residents, aged 15 - 69, from 84 administrative villages, 42 project townships and 16 project counties in Shanxi and Gansu, Qinghai, Xinjiang provinces.

Results: 5343 valid questionnaires included 2178 males and 3165 females, with the average age as 43.

Stereoselective characteristics and mechanisms of epidermal carboxylesterase metabolism observed in HaCaT keratinocytes.

There is increasing evidence that epidermal carboxylesterase may be involved in the stereoselective hydrolysis of prodrugs in percutaneous absorption. The present study was designed to evaluate the stereoselective characteristics and mechanisms of ketoprofen ethyl ester hydrolysis by epidermal carboxylesterase expressed in HaCaT keratinocytes. Ketoprofen ethyl ester was mainly hydrolyzed to R-ketoprofen by carboxylesterase of human HaCaT keratinocytes.
