[Validity and reliability of the Persian version of measurement of the quality of life of people with disabilities]

Improving disabled quality of life is considered as one of the goals of rehabilitation and maintaining and ameliorating quality of life has become an important aim of medical systems. This study aims at investigating psychometric properties of measurement of the quality of life of people with disabilities, which is developed by World Health Organization [WHO]. The questionnaire was translated based on the International Quality of Life Assessment Project [IQOLA]. 160 individuals over 18 years old with disability in Tehran [age average=50] performed in this study. Socio-demographic inventory, SF12 inventory, and finally WHOQOL-D were given to participants respectively. Validity, concurrent validity with quality of life questionnaire [short form 12] by using correlation coefficients pearson, face validity, content validity and discriminant validity with spearman correlation coefficients of internal consistency and stability by calculating Cronbach's alpha and determining the intraclass correlation coefficients [ICC] was assessed. Version 19 SPSS was used to perform statistical tests. Face and content validity of the questionnaire, simplicity, and clarity were approved phrases. Over 90% of scores with a correlation of each question with the scores of related subtest was significant and positive. These results indicate an appropriate discriminative validity of the test items. Estimating Cronbach's alpha [0.90] confirms high internal consistency of the inventory with the exception of social communication area [0.61]. The results of evaluating reliability using within subject correlation coefficient estimation show that there is a high correlation coefficient between different subtests of the inventory. Results indicate reliability and validity of Persian-version of mentioned inventory. Therefore, its utilization in research studies is highly recommended

[ comparison study of available range of movement in common commercial wrist orthoses in normal subjects]

Despite the high incidence of wrist diseases and general use of commercial wrist orthoses, there is not precise information concerning the extent of immobility that these orthoses provide. Thus this study aimed to investigate and compare the range of motion [ROM] achieved from four common commercial orthoses in normal subjects. Forty students from Rehabilitation faculty of Shahid Beheshti University of Medical sciences [22 females and 18 males] aged 19-25 years, with normal range of motion, and no history of injury or pain in the right wrist participated in this study. The ROM of the right wrist was measured by electrogoniometer. Then different commercial orthoses [Teknotan, Teb o sanat, LP and OPPO] were worn in random order. Then the subjects were asked to move their wrist in flexion and extension direction as much as possible. Each movement was repeated for three times. Sixty seconds rest time was applied between each successive orthosis. Data analysis performed using repeated-measure ANOVA test. Data analysis showed that the mean range of flexion [p=0.001] and extension [p<0.001] were significantly different among four orthoses. Bonferroni test showed that OPPO orthosis [40 +/- 10] permitted significantly less flexion in comparison with Teb o sanat and Tecnotan [p=0.003 and p=0.02, respectively]. Teb o Sanat orthosis [52 +/- 10] permitted significantly less extension in comparison with LP and Tecnotan [p=0.001 and p=0.006, respectively]. The results showed that none of these commercial orthosis immobilized the wrist. Therefore, specifications of the orthosis and the fitting of the orthosis with hand should be considered by the prescribers
