    Cross-Cultural Adaptation, Reliability and Validity of the Turkish Version of the Lower Limb Functional Index
    (2015) Duruturk, Neslihan; Tonga, Eda; Gabel, Charles Philip; Acar, Manolya; Tekindal, Agah; 0000-0002-4060-7048; 25777549; AAD-3908-2020; ACK-5152-2022
    Purpose: This study aims to adapt culturally a Turkish version of the Lower Limb Functional Index (LLFI) and to determine its validity, reliability, internal consistency, measurement sensitivity and factor structure in lower limb problems. Method: The LLFI was translated into Turkish and cross-culturally adapted with a double forward-backward protocol that determined face and content validity. Individuals (n = 120) with lower limb musculoskeletal disorders completed the LLFI and Short Form-36 questionnaires and the Timed Up and Go physical test. The psychometric properties were evaluated for the all participants from patient-reported outcome measures made at baseline and repeated at day 3 to determine criterion between scores (Pearson's r), internal consistency (Cronbachs alpha) and test-retest reliability (intraclass correlation coefficient - ICC2.1). Error was determined using standard error of the measurement (SEM) and minimal detectable change at the 90% level (MDC90), while factor structure was determined using exploratory factor analysis with maximum likelihood extraction and Varimax rotation. Results: The psychometric characteristics showed strong criterion validity (r = 0.74-0.76), high internal consistency (alpha = 0.82) and high test-retest reability (ICC2.1 = 0.97). The SEM of 3.2% gave an MDC90 = 5.8%. The factor structure was uni-dimensional. Conclusions: Turkish version of LLFI was found to be valid and reliable for the measurement of lower limb function in a Turkish population.

    Differences in Physical Activity and Physical Fitness Level in Patients with Fibromyalgia Syndrome and Healthy Individuals
    (2017) Ozkoslu, Manolya Acar; Tonga, Eda; Daskapan, Arzu; Karatas, Metin; Tekindal, M. Agah; 0000-0002-4060-7048; U-9270-2018
    Objective: The aim of this study was to investigate the physical activity and physical fitness levels in patients with fibromyalgia syndrome (FMS) and to compare the data with those in healthy individuals. Methods: The study included 82 patients with FMS and 110 healthy individuals. In order to compare physical activity levels, all the subjects responded to the International Physical Activity Questionnaire, Long Form (IPAQ). The health-related physical fitness of the subjects was evaluated by body composition, muscle endurance, cardiorespiratory endurance, flexibility, and balance. Body mass index (BMI), sit-up test, 6-min walk test, sit and reach test, body lateral flexion, and Kinesthetic Ability Trainer 3000 (KAT 3000) were used to determine body composition, muscle endurance, cardiorespiratory endurance, flexibility, and balance, respectively. Results: Of the patients with FMS, 36.6% were inactive, 45.1% were insufficiently active, and 18.3% were active. Of the healthy individuals, 40.9% were active, 36.4% were insufficiently active, and 22.7% were inactive. Significant differences were found (p<0.05) in IPAQ walking and total scores between the groups. The sit-up test scores (p<0.001) and right and left body lateral flexion scores (p<0.001) were significantly different between the FMS patient and control groups. Conclusion: Our results showed that the physical activity and physical fitness levels of patients with FMS were lower than those of healthy individuals.

    The sensitivity and specificity of the balance evaluation systems test-BESTest in determining risk of fall in stroke patients
    (2019) Sahin, Ilknur Ezgi; Guclu-Gunduz, Arzu; Yazici, Gokhan; Ozkul, Cagla; Volkan-Yazici, Melek; Nazliel, Bijen; Tekindal, Mustafa Agah; 0000-0002-4060-7048; 30814369
    BACKGROUND: Balance disorders cause disability in stroke and increase risk of falls. The Balance Evaluation Systems Test (BESTest), examines balance, determines parameters causing balance disorders, provides information on risk factors for falls. OBJECTIVE: To investigate the sensitivity and specificity of the BESTest in determining the risk of fall in stroke patients. METHODS: Fifty patients with chronic stroke were included in the study. Balance was assessed using BESTest, Berg Balance Scale (BBS), Activity Specific Balance Confidence scale (ABC) and Biodex-BioSway Balance System. To examine the content validity of BESTest, the relationship between BESTest and other balance assessment methods was examined. The internal consistency reliability of BESTest was evaluated by Cronbach's alpha coefficient. Analysis of receiver operating characteristics (ROC) was performed to determine cut-off point, sensitivity and specificity. RESULTS: BESTest, BBS, ABC and Biodex-BioSway Balance System results of faller stroke patients were worse than that of non-faller (p < 0.05). Internal consistency of BESTest was found to be Cronbach's alpha = 0.960. The BESTest value of area under the curve (AUC) was 0.844, with a cut-off point of 69.44%, a sensitivity of 75% and a specificity of 84.6% (p < 0.01). CONCLUSION: BESTest is reliable and valid with high sensitivity and specificity in determining the risk of fall in stroke patients.
