Translation, validity, and reliability of the Foot Posture Index (FPI-6) - Turkish version.

Purpose: The aim of this study was to translate the English version of the Foot Posture Index (FPI-6) into Turkish and to examine its psychometric properties.

Methods: After the forward-backward translation process, the internal consistency and intra - and inter-rater reliability were evaluated by using Cronbach's α and Intraclass Correlation Coefficient (ICC) (two-way random effects model with absolute agreement type), respectively. The agreement between reliability assessments was investigated by the standard error of measurement (SEM) and the minimal detectable change (MDC).

Effect of intramuscular fat in the thigh muscles on muscle architecture and physical performance in the middle-aged women with knee osteoarthritis.

Background: We investigated intramuscular fat (IMF) in quadriceps femoris (QF) and hamstring muscles in the middle-aged women with knee osteoarthritis (KOA). We also examined the relationship between muscular infiltration of QF and hamstring muscles and muscle architecture and physical performance of the women with KOA.

Methods: In this cross-sectional study, 72 women were included.

Effectiveness of supervised and functional level-based exercise program in elderly inpatients: Randomised controlled trial.

Objective: The aim of this study was to compare the effectiveness of supervised and unsupervised functional level-based exercises program for elderly inpatients on physical activity, mobility, health-related quality of life and depression status.

Design: A single-blinded randomised controlled trial.

Setting: Internal medicine service.

Ultrasound imaging of quadriceps muscle in patients with knee osteoarthritis: The test-retest and inter-rater reliability and concurrent validity of echo intensity measurement.

Background: Echo intensity(EI) on ultrasonography images of skeletal muscle reflects muscle composition.

Objectives: The primary aim of the study was to investigate the inter-rater and test-retest reliability of EI using grayscale histogram analysis of the cross-sectional area of quadriceps femoris(QF) muscle in patients with knee osteoarthritis(KOA). The secondary aim of the study was to determine the concurrent validity of the Free Hand Tool(FHT) when compared to Rectangular Marquee Tool(RMT) for calculating the region of interest(ROI) in ImageJ.

Reliability and Validity of the Turkish Version of the Oxford Participation and Activities Questionnaire in Older People.

Background: Activities and participation play important roles in the maintenance of healthy aging. The maintenance of these factors optimizes social life to increase the quality of life with aging. However, there is a lack of questionnaires in Turkish to evaluate activity and participation among older people.
