    PurposePeople with Parkinson's disease (PD) can develop cognitive and physical impairments. There is limited evidence on the association between executive function and physical function in people with PD.ObjectiveWe aimed to investigate the association between the executive and physical functions in people with Parkinson's disease (PD) by comparing healthy controls.MethodThirty-three patients diagnosed with PD and 33 healthy controls were included in the study. PD group was divided into two subgroups according to their scores on executive tests as high performers (PD-HPs; n = 17) and low performers (PD-LPs; n = 16). The severity of motor symptoms disease severity, executive function, global cognitive function, reaction time, hand function, functional capacity, physical activity, and balance confidence was assessed by the validated instruments.ResultsThe PD group had less physical function and executive function compared to healthy controls (p < 0.05). The PD-LPs group had less physical and cognitive function than the PD-HPs group (p < 0.05). The executive functions were significantly correlated with almost all variables in both people with PD and healthy people, and correlations were moderate to strong (p < 0.05). However, the correlation coefficients were relatively higher in people with PD compared to healthy controls.ConclusionThere was a significant association between executive and physical function in people with PD. Future studies should be conducted to determine whether the treatment of one of these dysfunctions affects the other.

    Comparison of Muscle Endurance and Balance in Patients with Shoulder Impingement and Healthy Controls
    (2024) Çekok, Fatma Kübra; Gökşen, Ayşenur; Caylak, Remzi; Kahraman, Turhan; Genç, Arzu
    Aim; Chronic pain has been theorized to hinder balance control by compromising muscle endurance. Despite this theoretical connection, there is limited empirical evidence on this phenomenon, especially in patients diagnosed with shoulder impingement. This study aims to investigate muscle endurance, balance measures, and indicators of shoulder dysfunction in patients with impingement, comparing them with age- and sex-matched healthy controls. Method; In this cross-sectional study, patients (n=31) with shoulder impingement and healthy controls (n=23) matched for age and gender were compared with regard to their balance ability and physical performance. Functional questionnaires (Disabilities of the Arm, Shoulder, and Hand (DASH) as well as Single-Leg Stance Balance Test (SLBT), Y Balance test, Scapular Endurance Test, Trunk muscle flexor and extensor test, grip strength and Nine-Hole Peg Test (NHPT) were completed in a randomized order with consistent raters. Results; Patients with shoulder pain showed significantly worse results in measurements of shoulder function (p<0.01), scapular and trunk muscle endurance (p<0.01), as well as balance dominant/nondominant balance ability right/left (p<0.01) compared to healthy controls. Conclusion; Patients with shoulder impingement had lower muscle endurance balance and hand measurements compared with healthy people. This difference was statistically significant. Health and fitness specialists should take into account the risk-related adjustments associated to balance when recommending upper-extremity exercises in patients with shoulder impingement.

    Translation, cross-cultural adaptation, reliability, and convergent and known-group validity of the Turkish full version of the Hip Disability and Osteoarthritis Outcome Score in patients with hip osteoarthritis
    (Turkish League Against Rheumatism, 2024) Goksen, Aysenur; Caylak, Remzi; Cekok, Fatma Kuebra; Kahraman, Turhan
    Objectives: The study aimed to culturally adapt the full version of the Hip Disability and Osteoarthritis Outcome Score (HOOS) into Turkish and evaluate its reliability and validity.Patients and methods: Patients with hip osteoarthritis were included in the methodological crosscultural adaptation study between May 2022 and December 2022. We translated and adapted the HOOS into a Turkish version and validated it in a cohort of native Turkish-speaking patients with hip osteoarthritis. The HOOS includes five subscales named symptoms, pain, activities of daily living (ADL), sport and recreation (Sport/Rec), and quality of life (QoL). The psychometric properties of the Turkish HOOS were assessed. The reliability was investigated using test-retest reliability (intraclass correlation coefficient; ICC) and internal consistency methods (Cronbach's alpha). The convergent validity of the Turkish HOOS was evaluated by testing the predefined hypotheses using the correlations with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the European Quality of Life Scale (EQ-5D-3L), a generic QoL scale. Results: A total of 202 patients (131 females, 71 males; mean age: 55.2 +/- 9.7 years; range, 50 to 70 years) were recruited for the study. Cronbach's alpha values for each subscale of the HOOS were as follows: symptoms=0.76, pain=0.94, ADL=0.96, Sport/Rec=0.87, QoL=0.78, and total score=0.98, indicating it has high internal consistency. For all subscales and total score of the HOOS, the ICC values were between 0.77 and 0.86, indicating good to excellent test-retest reliability. All correlations between each subscale and total score of the Turkish HOOS, WOMAC, and EQ-5D-3L were moderate to strong. Therefore, 23 predefined hypotheses out of 24 were confirmed with a confirmation rate of 96%, indicating the Turkish version of the HOOS had adequate convergent validity.Conclusion: This study shows that the Turkish version of the HOOS has a convergent and knowngroup validity, internal consistency, and test-retest reliability. It can be used to assess the patient's perception of their hip and associated difficulties, as well as their symptoms and functional limitations.
