(Human Kinetics Publ Inc, 2025) Yazgan, Elif Aleyna; Coskunsu, Dilber Karagozoglu; Ozdincler, Arzu Razak
Context: To cross-cultural translate the Cumberland Ankle Instability Tool (CAIT) to Turkish version (CAIT-T) and to evaluate the validity, reliability, and cutoff score of CAIT-T for Turkish athletic population. Design: The English version of CAIT was translated to CAIT-T based on a guideline of cross-cultural adaptation. Fifty-two athletes with chronic ankle instability and 63 athletes without chronic ankle instability were included in the study. Construct validity was evaluated with correlations between the CAIT-T, Turkish version of Foot Ankle Ability Measure (FAAM-T), and Numeric Rating Scale. CAIT-T was completed twice by each participant at 7 to 10 days intervals to assess test-retest reliability based on the intraclass correlation coefficient, whereas Cronbach alpha evaluated internal consistency. Discriminative validity and content validity of the CAIT-T also evaluated. Results: In construct validity, strong positive correlation was found between CAIT-T and Numeric Rating Scale perceived ankle instability (rho = -.771, P<.001), as well as moderate negative correlations with FAAM-T-activities of daily living and FAAM-T-sports (rho = -.448, P < .001 and rho = -0.541, P < .001, respectively). The CAIT-T demonstrated strong test-retest reliability (intraclass correlation coefficient score of .98) with a good internal consistency (Cronbach alpha: .85). Receiver operating characteristic curve showed a cutoff score of 26.5 (Youden index: 0.78, sensitivity: 0.57, specificity: 0.90.5). No ceiling or floor effects were observed. Conclusions: CAIT-T is a valid and reliable questionnaire for the assessment of chronic ankle instability in the Turkish athletic population.

The Effectiveness of Blood Flow Restriction Training on Upper Extremity Muscle Strength: a Systematic Review
(Georg Thieme verlag Kg, 2024) Özdinçler, Arzu; Atli, Ecenur; Ozdincler, Arzu Razak; Fizyoterapi Ve Rehabilitasyon Bölümü
Objective This systematic review aims to investigate the effect of blood flow restriction training (BFRT) on upper extremity muscle strength in pathological conditions of the upper extremity musculoskeletal system or in healthy individuals. Materials and Methods This study was conducted in accordance with the PRISMA guideline statement. The randomized controlled studies which published from January 2000 to May 2022 were searched in the PubMed, Web of Science, MEDLINE, Scopus, and Cochrane Library databases. Inclusion criteria were healthy clinical population or musculoskeletal pathology related to the upper extremity, participants aged 18 and above, application of blood flow restriction to the arm, a randomized controlled study design, and publication in English. Additionally, the presentation of upper extremity muscle strength as an outcome measurement was required. The quality of the studies was evaluated using The Physiotherapy Evidence Database (PEDro) scale. Articles that were non-randomized, inaccessible in full text, and scored 4 or below on the PEDro scale were excluded. Results Five studies were included with 219 participants. The included studies had PEDro scores ranging from 5 to 8, with an average score of 6.4. This review demonstrated a positive or neutral effect of BFRT on grip strength and shoulder strength. Conclusion Although some studies have reported positive effects of BFRT on upper extremity muscle strength, there is no conclusive evidence regarding the protocol to be used for increasing upper extremity muscle strength.
