Read More Background: This study aimed to prepare the Persian version of Speech, Spatial, and Qualities of Hearing Scale questionnaire-12 (SSQ-12-Persian version) and assess its validity and reliability to facilitate the effect of the usage of hearing aids on individuals using them.Methods: This study is considered an original research type of article. The questionnaire was translated to Persian according to WHO method. Firstly, two fluent Persian-speaking translators translated the questionnaire from Persian to English, and then three audiologists examined the questionnaire. The questionnaire was then translated from Persian to English and conceptually reviewed by two bilingual translators. Finally, 99 senior persons aged 22 to 52 years who used hearing aids and had their hearing thresholds assessed lately were given the Persian version of the Speech, Spatial, and Qualities of Hearing Scale 12 (SSQ-12) questionnaire. T-test examination and Cronbach Alpha were used to assess the reliability and validity and test-retest reliability.Results: Persian version of the SSQ-12 questionnaire showed high internal consistency (assessed by Cronbach Alpha = 0.924) and high test-retest (assessed by Cronbach Alpha = 0.868) reliability.Conclusion: SSQ-12 questionnaire is a comprehensive summary of the SSQ-49 questionnaire. It would be one of the valid questionnaires to evaluate hearing performance improvement in hearing aids users. The paired sample t-test revealed that the Persian version of the SSQ-12 questionnaire has good reliability and validity, and Cronbach's alpha revealed that the questionnaire has strong internal consistency (Cronbach's alpha =0.924).The reliability of the test-retest after a month was obtained, and the total scale result was 0.867. According to this study's results, SSQ-12 can be used as other Persian translated questionnaires like GHABP, SHQ, and IOI-HA for examining the effectiveness of hearing aids and their effects on limiting disabilities related to hearing loss.

Read More Background: 3D scanners are used to obtain three-dimensional (3D) shapes of body parts, offering an alternative to conventional techniques such as casting and a variety of potential advantages. However, 3D scanners are usually very expensive and not affordable and accessible for most orthotists and prosthetists, especially in developing countries. Therefore, this study aimed to evaluate the validity and reliability of a low-cost handheld and affordable 3D scanner (3Dsystems, ‘sense’) for use in orthotics and prosthetics. Methods: The validity and reliability of the 3D Sense scanner were assessed through repeated scanning and measurement of the predefined circumferences of the stumps of four transtibial amputees and 8 body cast models. Two assessors performed digital scanning and tape measurement on two different days, each consisting of three trials per condition/day. The reliability of the 3D sense scanner was assessed by investigating between trials, the assessors, and day reliability using Intraclass Correlation Coefficients. The standard error of measurement (SEM) was also calculated to assess measurement error. The validity of the 3D sense scanner was assessed using correlation analysis, mean percentage error (the mean differences between scanner and tape measure), and Bland-Altman statistics. Results: The 3D Sense scanner provides stumps and body cast model measurements with similar reliability to the tape measure. Reliability coefficients for the 3D scanner are relatively high (ICC). The ICCs all are near 1.0 and SEMs all range from 0.06 to 0.10. The 3D Sense scanner demonstrated excellent validity. There was a significant positive correlation between the 3D scanner and tape measure for both stumps and body cast models measurements (r > 0.850; p < 0.0001). The measurement error between the 3D scanner and tape measure is very low as indicated by mean differences close to zero. Conclusions: This study introduces a low-cost handheld and affordable 3D scanner, which has proven to be a valid and reliable clinical tool in orthotics and prosthetics. This 3D scanner would have extensive and powerful clinical applicability resulting in valid and reliable digital information of body segments for computer-aided design (CAD) of orthotics and prosthetics.
