Aims: Neck pain is a common disorder among computer users that can reduce the personal yield. So the prevention of it is an important matter in computer users. The purpose of this study was to evaluate the effect of a period of exercise therapy and an ergonomic intervention on chronic neck pain and disability among computer users. Materials & Methods:In this quasi-experimental cross-sectional study in 2012, 30 female computer users of Lorestan University of Medical Sciences with at least 6 months experience of neck pain were selected purposefully by a demographic questionnaire. Subjects were located in experimental (n=15) and control (n=15) groups. The experimental group received therapeutic exercises and ergonomic intervention for two months but control group received no therapeutic intervention. The rate of neck pain and disability was measured by chronic neck pain and disability index questionnaire before and after of exercise therapy and ergonomic intervention. Data were analyzed by independent T test and Pearson correlation coefficient in SPSS 16 software. Findings: There were significant differences between mean of chronic neck pain and disability scores of the two groups (p<0.05). But there were no significant relationships between neck pain, disability and the subjects' work experience. Conclusion: Exercise therapy along with ergonomic intervention is useful for treatment of chronic neck pain.

Comparison the Precision of Ear and Finger Pulse Oximetry with Finger Sensor in Mechanically Ventilated ICU PatientsKeywords Oximetry; Arterial Oxygen Saturation; Intensive Care Units Aims Nowadays, the pulse oximetry is widely used to monitor the oxygen saturation constantly. In the clinical care, it is observed that the ear pulse oximetry with the finger sensor is sometimes utilized in the ICUs. The aim of the study was to determine the accuracy of the ear pulse oximetry and the fingertip with the finger sensor in the ICU patients under the mechanical ventilation. Materials & Methods In the analytic comparative study, 60 hospitalized patients under the mechanical ventilation in the ICU of Moddares Hospital in Kashmar Township were studied in 2015. The subjects were selected via available convenience sampling method. One finger pulse oximetry sensor having been attached to the upper part of the ear and the other to the fingertip, the arterial blood sampling was done simultaneously. Data was analyzed by SPSS 22 software using repeated ANOVA and Spearman correlation tests. Findings Mean oxygen saturation percentage and the heartbeat of ear, fingertip, and arterial blood pulse oximetry were significantly different (p<0.001). In addition, the oxygen saturation percentage of ear, fingertip, and arterial blood pulse oximetry was significantly correlated by the partial pressure of oxygen (PaO2; p=0.001). Nevertheless, the mentioned parameters were not significantly correlated by the peripheral edema and especially, by the hand (p>0.05). Conclusion The utilization of ear pulse oximetry with the finger sensor on the fingertip cannot lead to accurate results of the oxygen saturation in the hospitalized patients in the ICU under the mechanical ventilation. However, in case of any reduction in the arterial blood oxygen pressure, the accuracy of the finger pulse oximetry starts to drop out.

Aims: Long term prognosis of hemodialysis patients are influenced by adequacy treatment. Thus, it is important to study the factors that improve the adequacy dialysis. The aim of this study was to determine the impact of isometric and isotonic movements during hemodialysis on dialysis adequacy. Materials & Methods: In this clinical trial in 2014, 50 patients in the two dialysis centers of Gonabad City and Qaen City, Iran, were selected by simple random sampling method and considering the inclusion criteria. The samples were randomly divided into two equal experimental and control groups. Experimental group patients performed isometric and isotonic movement according to tutorial film for 60 minutes in the first 2 hours of hemodialysis. These sport movement were repeated 3 times a week during hemodialysis session for 6 weeks. Dialysis adequacy was calculated before and after intervention in 2 groups. Data was analyzed by SPSS 14.5 software using independent T, Chi-square, Pearson-and Spearman correlation coefficients tests. Findings: After the intervention, there was a significant difference between two groups in adequacy of dialysis (p=0.01), in a way that before intervention, 80% of patients in experimental group had dialysis adequacy less than 1.2 which was reduced to 40% after intervention. However, the number of patients with less than 1.2 adequacy of dialysis in control group was increased from 72 to 76%. Conclusion: Performing isometric and isotonic movements during hemodialysis improves the adequacy of dialysis in hemodialysis patients.
