    Purpose: Manual asymmetry refers to tendency that is in favor of hand to perform manual tasks requiring skills, it is important in every sensory and motor function. This study aimed to compare the muscle activation, proprioception, and anthropometric characteristics of the dominant and non-dominant wrists. Methods: In the study, forty young individuals aged between 18-25 years, who volunteered to participate, were included. As anthropometric measurements, the upper extremity length measurement forearm length measurement, hand length measurement wrist diameter measurement, hand width, shape and digit index measurements were performed, respectively. The muscle strength of wrist flexor and extensor muscles was measured by a hand dynamometer, while their muscle activations were measured by electromyography. The arm carrying angle was evaluated by a universal goniometer. Results: The mean age of the individuals included in the study was 22.51 +/- 0.35 years. In the right dominant individuals, when the dominant and non-dominant sides were compared, a statistically significant difference was found between flexor muscle activations, muscle strength, and hand width (p<0.05). No difference was detected between the digit and shape indices, proprioception, wrist diameter, forearm length, cubital angles, and upper extremity length (p>0.05). Conclusion: Finding the dominant side's wrist flexor muscle activations, extensor muscle strength, and hand widths better in young individuals showed that the dominant side was frequently used in daily living activities. The difference was seen that the non-dominant side would be weaker and at higher risk of deformity with increasing age and in the presence of any rheumatic, orthopedic, and neurologic diseases.

    Comparison of gait speed, dynamic balance, and dual-task balance performance according to kinesiophobia level in older adults
    (Taylor & Francis Ltd, 2023) Kocaman, Ayse Abit; Arslan, Saniye Aydogan
    PurposeThe presence of kinesiophobia was identified in older adults. Studies have examined the effects of kinesiophobia in older adults with chronic pain. Studies examining the effect of kinesiophobia on gait and balance performance in older adults without pain are insufficient. The aim of this study was to compare gait speed, dynamic balance, dual-task balance performance according to kinesiophobia level in community dwelling older adults without pain.Materials and methodsSeventy-five older adults were included. The socio-demographic data (age, height, weight, fall history, etc.) was recorded. Older adults were divided into two groups based on Tampa Kinesiophobia Scale scores. Scores below 37 were grouped as low level, scores above 37 were grouped as high level. The mini-mental state examination (MMSE), gait speed test, modified Four Square Step Test (mFSST), Five Times Sit-to-Stand Test, dual-mFSSt test (additional cognitive and motor task) were applied for dual-task balance performance.ResultsThirty-six participants(mean age 70.58 +/- 5.59 years) had low kinesiophobia, the other 39 individuals(mean age70.94 +/- 7.45 years) had high kinesiophobia. The age, gender, body mass index, cognitive status, and fall history were similar between groups (p > 0.05). The participants with low kinesiophobia were found to have better gait speed, dynamic balance, dual-task balance performance (p < 0.001).ConclusionThis study results showed that the presence of high level of kinesiophobia affects gait speed, dynamic balance, dual-task balance performance, and dual-task cost in older adults. Therefore, a high level of kinesiophobia can lead to falls. It may be important to investigate the effects of kinesiophobia in older adults.

    (Taylor & Francis Ltd, 2021) Sertel, Meral; Arslan, Saniye Aydogan; Yumin, Eylem Tutun; Demirci, Cevher Savcun; Simsek, Tulay Tarsuslu
    Aims This study aims to investigate the relationship between physical activity, fear of movement and fear of falling in older adults with chronic pain. Materials and methods The study includes 163 older adults aged 65 years and over, who live in a private nursing home. The cognitive functions of the individuals who participated in the study were evaluated with the mini-mental examination scale (MMES), fears of movement with the Tampa Scale of Kinesiophobia (TSK), fear-avoidance behaviour with the Fear-avoidance Beliefs Questionnaire (FABQ), physical activity levels with the Physical Activity Scale for Older (PASE), and the fears of falling were assessed with Tinetti's Falls Efficacy Scale (FES). Results In the correlation analysis, there was a weak correlation between age and fall risk (r = 0.349, p < 0.001), and PASE(Total) score (r = -0.020, p = 0.011). There was a weak positive correlation between Tinetti FES and FABQ scores (r = 0.349, p < 0.001), and kinesiophobia value (r = 0.259, p < 0.001), there was a weak negative correlation between Tinetti FES and PASE(Total) (r = -0.241, p = 0.002). A positive mid correlation was determined between kinesiophobia and the FABQ scores (r = 0.41, p < 0.001). The established regression model was found to be significant (F = 12.175; p < 0.001). Among the independent variables included in the model, FABQ(Total) (t = 3.589; p < 0.0001) and PASE(Total) (t = -3.325; p < 0.0001) significantly affected the fear of falling. Conclusion The presence of chronic pain in older adults who have problems related to physical activity, fear of falling, and kinesiophobia due to advancing age may affect social participation, functional level, and quality of life significantly. Therefore, pain should be addressed in older adults and should be considered as an important issue in rehabilitation programs.

    Neural System and Its Adaptation to Exercise
    (Springer International Publishing, 2023) Demirci, Cevher; Arslan, Saniye Aydogan
    Neural adaptation is the improvements in coordination and learning allowing the involvement and deactivation of relevant muscles during a forceful task. It occurs at the level of the motor cortex, spinal cord, and/or neuromuscular junction following exercise and varies at significant levels with different exercise training. It is already known that the rapid increase in muscle strength, before the development of hypertrophy in the muscle with exercise, is mainly associated with neural adaptations. Optimizing motor control is the focus of many training and rehabilitation programs. Therefore, understanding how neural adaptations occur and their relationship with functional development is crucial for planning exercise programs. Studies investigating the response to exercise in neural system pathologies are insufficient in the literature. To plan an individualized and functional exercise program, it is necessary to know these effects in healthy individuals as well as in patients. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

    (Allied Acad, 2017) Sertel, Meral; Arslan, Saniye Aydogan; Kurtoglu, Fatih; Yildirim, Tezel Sahan
    Background: In aging process was to show to change physical activity, depression and quality of life values of individuals aged 18-85. Methods: Four hundred and fifty individuals aged 18-85 who lived in Kirikkale were included in our study after being determined with the Simple Randomization Sample Method. Three hundred and forty one individuals who were suitable for our inclusion and exclusion criteria completed the study. The individuals were divided into 3groups: 142 adults (18-45 aged), 137 middle-aged (45-64 aged) and 62 elderly (>65aged). Quality of life values were measured with Nothingham Health Profile (NHP), physical activity levels of the individuals were measured with 24 h Physical Activity Scale (PAS), depression status of individuals were determined with Beck Depression Scale (BDS). Results: Our study showed that statistically meaningful significance was found when we compared the groups with quality of life and depression. Statistically meaningful significance was specified on PAS measurement in groups with PAS work and sum of PAS variables (p<0.005). There was no difference between PAS and the other variables in groups (p>0.005). Conclusion: In summary, our results point that elderly individuals have a sedentary and depressive life style. In all groups, physical activity habits support physiological wellness state and health-related quality of life by strengthening physical functionality. Because of that, studies on strengthening and encouraging physical activity must be planned.

    (DOKUZ EYLUL UNIV INST HEALTH SCIENCES, 2020) Arslan, Saniye Aydogan; Sertel, Meral; Demirci, Cevher Savcun; Erdal, Elif Sakizli; Muci, Birsen
    Purpose: The aim of our study is to evaluate the reliability and validity of the Turkish version of the Community Balance and Mobility Scale (CB&M-T) on older adults of Turkish population. Methods: The study included 145 older adults. Test-retest reliability, internal consistency was used for reliability. Berg Balance Scale was used to test the concurrent validity of the CB&M-T. The ceiling and floor effect were calculated for content validity. To measure the test-retest reliability, the older adults were assessed again with CB&M-T one week after the first assessment. ROC (Receiver Operating Characteristic) analysis was performed determine the cut-off scores and the area under the curve ( AUC) was calculated. Results: Very high relationship was found between the 1st and 2nd evaluation total CB&M-T score. Cronbach's alpha coefficient was excellent. There were no floor and ceiling effects. High correlations were found between CB&M-T and BBS. The optimum cut-off value is calculated as 38.5 points. AUC value of 0.90 is found to be highly acceptable for individuals at fall risk. Conclusion: This study indicates that the Turkish version of the CB&M-T scale is a reliable and valid balance and mobility scale that can be used in the rehabilitation of older adults with a high functional level. According to these results, Turkish clinicians have been brought a new scale that can be used in clinics We think that older adults with high functional levels will bring a new perspective to the literature to evaluate the fall risk, balance and mobility and to plan rehabilitation programs.

    (Springer-Verlag Italia Srl, 2024) Kocaman, Ayse Abit; Arslan, Saniye Aydogan; Bozkurt, Yusuf Emre; Coskun, Erdal
    Introduction Dubousset Functional Test (DFT) is an assessment test evaluating the functional capacity and dynamic balance. The study aimed to examine the reliability, validity, and responsiveness of the DFT in early stage Parkinson's disease (PD) patients. Methods This was a cross-sectional study. Thirty-three early stage PD patients were recruited. The DFT was performed along with the Timed Up and Go (TUG) test, dual-task TUG, Functional Reach Test (FRT), 3-m backward walk test (3MBWT), Tinetti Performance-Oriented Mobility Assessment (POMA), and Berg Balance Scale (BBS). Results The test-retest reliability of the subcomponents of the DFT was excellent. The ICCs were as follows: 0.952, 0.955, 0.917, and 0.919, respectively. The correlation with subcomponents of DFT and TUG, dual-task TUG, FRT, 3MBWT, BBS, and POMA was found to be statistically significant (p < 0.05). The standard measurement errors of the subcomponents of the DFT were 1.45, 1.39, 1.70, and 1.57, respectively. The minimal clinically important difference (MCID) of the subcomponents was 2.05, 1.97, 2.41, and 2.22, respectively. Conclusion The DFT is a reliable, valid, and easy-to-administer tool in assessing the balance and physical function of early stage PD patients.

    (Taylor & Francis Ltd, 2024) Yasa, Mustafa Ertugrul; Arslan, Saniye Aydogan; Sahan, Tezel Yildirim; Caglar, Derya; Demirci, Cevher Savcun; Demir, Pervin
    Purpose: To investigate the validity and reliability of the Turkish version of the Ottawa Sitting Scale (OSS-T) in patients with acute stroke.Materials and methods: The Berg Balance Scale (BBS) and Trunk Impairment Scale (TIS) were used to determine the validity of the OSS-T. The OSS-T was re-applied by the same rater after an interval of 7 days to determine the reliability. To test inter-rater reliability, the evaluation was repeated by a second rater 1 day after the first evaluation. Reliability was quantified using intraclass correlation coefficients (ICC), and validity was assessed by correlating the OSS-T scores with the results of the other measures.Results: The ICC of the total OSS-T score for inter-rater reliability was 0.996 and for intra-rater reliability, it was 0.951. The Cronbach's a coefficient used to determine internal consistency was 0.980, which indicates excellent reliability. A strong positive correlation was found between OSS-T and TIS (rho = 0.861, p < 0.001), and between OSS-T and BBS (rho = 0.875, p < 0.001). An evident 2-factor structure was shown by the results of the factor analysis.Conclusions: The results of this study indicated that the OSS-T has strong measurement properties, making it a valid and reliable tool for research and clinical practice in patients with acute stroke.
