LLA rehabilitation is a topic that requires the focus of current and future studies; evidence-based studies are required on the approaches to rehabilitation for specific LLA groups.

Background: Evaluation of prosthesis and orthosis (P&O) devices and service satisfaction in patients using P&O are important to understand the patient perspective and improve the quality of devices and the services.Objective: The aim of this study was to translate the original Orthotics and Prosthetics Users' Survey (OPUS) satisfaction module into Turkish and examine its psychometric properties in lower limb P&O users. Study Design: Cross-sectional study. Methods: The Turkish versions of the OPUS-Client Satisfaction with Device (CSD) and Service (CSS) modules were applied to 157 individuals using a lower limb prosthesis or orthosis. The retest of the survey was applied 5-7 days later. Intraclass correlation coefficient was used to determine test-retest reliability, and Cronbach alpha was used to determine internal consistency. Criterion validity was evaluated using the Nottingham Health Profile. Exploratory factor analysis was used to examine the factor structure of the Turkish version of the OPUS satisfaction module. Results: The test-retest correlation (intraclass correlation coefficient 5 0.92 for CSD and 0.91 for CSS) and internal consistency (Cronbach's alpha 5 0.84 for CSD and 0.95 for CSS) were high. A statistically significant correlation was found between the OPUS CSD and CSS modules and the Nottingham Health Profile (r 5 20.325 for CSD module, r 5 20.381 for CSS module, P , 0.001). The factor analysis revealed one-factor structure for both modules.Conclusions: This study demonstrated the reliability and validity of the Turkish version of the OPUS satisfaction module, and it provides a useful starting point for future studies on this survey.

Background: It is well known that questionnaires and scales are easy to use, cheap, and provide fast results. In the clinical setting, it will be easier and more comfortable to evaluate lower-extremity functions in both prosthesis and orthosis users with a single questionnaire.Objectives: To study the Turkish version of the orthotics and prosthetics users' survey lower-extremity functional status (OPUS-LEFS) and investigate its reliability and validity in the Turkish prosthesis and orthosis users. Study design: After forward and backward translation process, test-retest, internal consistency, validity, dimensionality, and Rasch analysis were done for 139 participants. Methods: Participants with a lower-limb prosthesis or orthosis were recruited in this study. Test and retest of the survey was done 1-3 days apart. For convergent validity, Nottingham Health Profile was used. Pearson correlation coefficient was used to analyze test-retest reliability; Cronbach's alpha for internal consistency, Spearman's correlation coefficient for validity, exploratory factor analysis by means of Kaiser-Meyer-Olkin and Bartlett's value of sphericity for dimensionality, and Rasch analysis were used. Results: Test-retest reliability of OPUS-LEFS showed very strong correlation (0.994) and for internal consistency with Cronbach's alpha value 0.71 of the Turkish version of OPUS-LEFS. Analyses showed that OPUS-LEFS is valid (p , 0.001) and significant (p , 0.001). Conclusions: The Turkish version of the OPUS-LEFS has been shown to be a valid and reliable tool in evaluating both orthosis and prosthesis users with a self-administered questionnaire for LEFS.

Amaç: Bu çalışmanın amacı, çocukların kullanmış olduğu ayakkabılara ait özelliklerin işitme engelli çocuklarda dinamik ve statik olarak ölçülebilen plantar basınç dağılım parametreleri ve denge parametreleri üzerine etkisinin olup olmadığını araştırmak ve işitme engeli olmayan çocuklarla karşılaştırmaktır. Yöntem: Çalışmaya 68 işitme engelli ve 68 sağlıklı olmak üzere toplam 136 çocuk dahil edildi. Çocukların ayakkabılarını değerlendirmek amacıyla Ayakkabı Uygunluğu Değerlendirme Formu (AUDF) uygulandı. Çocukların statik dengesini değerlendirmek için Flamingo Denge Testi (FDT), dinamik dengesini değerlendirmek için Fonksiyonel Uzanma Testi (FUT) kullanıldı. Pedobarografik ölçümlerde sensörlü yürüyüş platformu (RsScan-Footscan® pedobarogarfi sistemi (RsScan-FootScan lab ltd., Ipswich, England)) kullanıldı. Sonuçlar: İşitme engelli çocuklarda sağ ayağa ait AUDF ile toplam yüklenme oranı değerleri arasında pozitif ilişki; sağlıklı çocuklarda ise sağ ayağa ait AUDF ile ayağın arka bölümüne yapılan yüklenme oranı arasında negatif ve sol ayağa ait AUDF ile ayağın ön bölümüne yapılan yüklenme oranı değerleri ile arasında pozitif ilişki olduğu gözlemlendi (p<0,05). Her iki grupta AUDF ile denge testleri, dinamik ayak taban basınç değerleri, yürüme parametreleri arasında anlamlı ilişki bulunmamıştır (p>0,05). Tartışma: İşitme engelli çocuklarda ayakkabı uygunluğunun dominant ayakta statik yüklenme oranı ile artış göstermesi denge problemi olan çocukların kendilerini daha güvende hissetmek için dominant ayağa daha fazla oranda yüklendiklerinin bir göstergesi olabilir.
