    Investigation of knee joint position sensation balance reaction time and function in individuals with knee osteoarthritis and unilateral total knee arthroplasty
    (Sage Publications Inc, 2025) Yurttas, Ayse Nihal; Araci, Ayca; Akkoyun Sert, Ozlem; Ismayilov, Toghrul
    Objective: The aim of this study was to evaluate and compare the joint position sense of individuals diagnosed with knee osteoarthritis (OA), unilateral total knee arthroplasty (TKA) for knee OA and healthy individuals and to examine the effect of joint position sense (JPS) on balance, physical performance, reaction time, kinesiophobia, pain stiffness and function. Method: Sixty participants (n = 20 per group) were assessed using the RateFastGonio (R) app for JPS at 15 degrees, 45 degrees, and 60 degrees, the Berg Balance Scale (BBS) for balance, the Nelson Foot Reaction Test for reaction time, time up and go (TUG) and Stair Climb Up and Down Test (SCUDT) for physical performance, the Tampa Scale for kinesiophobia, and the The Western Ontario and McMaster University Osteoarthritis Index (WOMAC) for pain, stiffness, and physical capacity. Results: The results revealed no statistically significant differences in JPS and reaction time across the three groups (p > 0.05). However, balance scores were significantly higher in healthy individuals compared to the OA and TKA groups (p < 0.05). Physical performance scores (TUG and SCUDT) were significantly better in the healthy group, with OA patients performing better than the TKA group (p < 0.05). Kinesiophobia, pain, stiffness, and functional impairment were all significantly lower in healthy participants (p < 0.05). While JPS values were not significantly correlated with most variables, a moderate, positive correlation was observed between JPS at 60 degrees and reaction time in the OA group, and between JPS at 15 degrees and TUG results in the healthy and OA groups. Conclusion: In conclusion, both TKA and OA negatively impact balance and physical performance and contribute to movement related fear. Although TKA affects JPS, it does not appear to enhance it. These findings highlight the need for preventive and rehabilitative interventions, including proprioceptive training, particularly given the growing elderly population.

    Reducing smartphone addiction through calisthenic exercises: A randomized controlled trial
    (Springernature, 2025) Karaca, Osman; Yilmaz, Kamil; Yurttas, Ayse Nihal
    Purpose Smartphone addiction has become widespread, whereas physical activity-despite its proven benefits-has been declining in recent years. The first aim of this study was to investigate the effects of calisthenic-exercise training programs on smartphone addiction in young adults. The second aim was to examine the effects of calisthenic exercise on sleep and headaches. Methods A total of 40 participants were randomly divided into two groups: the calisthenic-exercise group (CalExG) in which participants performed calisthenic exercises 3 times a day for 8 weeks, and the control group (CG) in which participants did not perform any application. Smartphone addiction, sleep quality, and headache were assessed with the Smartphone Addiction scale short form (SAS-SF), Pittsburgh sleep quality index (PSQI), and visual analog scale (VAS), respectively. Results Within-group analyses revealed that participants in the CalExG had significant decrease in SAS-SF, PSQI, and VAS-headache scores (p < .01). There was no significant difference in all evaluated parameters of the participants in the CG (p > .05). Although there was a decrease in all parameters in the CalExG compared to CG, no statistically significant difference was found in the intergroup analyses (p > .05). Conclusions Calisthenic exercise could be used to reduce smartphone addiction. In addition, calisthenic exercises could be beneficial to improving sleep quality and reducing headaches. We believe that these results are important for health professionals interested in the subject and those working in different fields, such as educators.

    YouTube videos as an information source about exercises for temporomandibular disorders
    (Wroclaw Medical Univ, 2024) Tok, Ozlem Nur; Yurttas, Ayse Nihal; Tas, Serkan
    Background. Temporomandibular disorders (TMD) are musculoskeletal and/or neuromuscular conditions that affect the muscles, joints and associated structures of the stomatognathic system. Objectives. This study aimed to evaluate the quality and reliability of publicly available English-language videos on YouTube about TMD exercises, and to examine the video sources and professional groups responsible for the creation of the videos. Material and methods. The quality and reliability of the YouTube videos related to TMD exercises were evaluated using the DISCERN score, the global quality scale (GQS) and the JAMA (Journal of the American Medical Association) score. Results. Of the 121 videos evaluated, 30 (24.8%) were uploaded by professional organizations, 49 (40.5%) by health information websites, and 42 (34.7%) were uploaded by independent users. Professional organizations had a significantly higher number of subscribers, likes, comments, and views than healthcare webpages and independent users (p < 0.001). The duration of videos uploaded by independent users was significantly longer than that of videos uploaded by healthcare webpages (p = 0.018). With regard to the profession of the video narrators, the unspecified group exhibited significantly lower JAMA (p < 0.001), GQS (p = 0.011) and DISCERN scores (p = 0.002) compared to chiropractors, physiotherapists, physicians, and other healthcare professionals. The JAMA scores for physicians, personal trainers and chiropractors were significantly lower than those for other healthcare professionals (p < 001). The JAMA score was positively correlated with the GQS (r = 0.469, p < 0.001) and DISCERN (r = 0.505, p < 0.001) scores. Similarly, the DISCERN score was positively correlated with the GQS score (r = 0.924, p < 0.001). Conclusions. Despite the abundance of video content on YouTube about TMD exercises, the quality of these videos is low, and their reliability is questionable.
