    An Investigation Of The Effects Of Pes Planus On Distal And Proximal Lower Extremity Biomechanical Parameters And Low Back Pain
    (Turkey Assoc Physiotherapists, 2019) Unver, Banu; Suner Keklik, Sinem; Yildirim Sahan, Tezel; Bek, Nilgun
    Purpose: The objective of the study was to compare the biomechanical features of the lower extremity, foot structure, and function and low back pain in young sedentary subjects with and without pes planus. Methods: The study was conducted with the participation of 60 sedentary subjects consisting of 30 women and 30 men. The subjects were assigned to two groups as with or without pes planus according to navicular drop test results. The American Orthopaedic Foot and Ankle Society score and Visual Analogue Scale Foot and Ankle Scales were used to evaluate the foot function of the subjects. Muscle shortness and strength tests of the selected muscles, Q angle, and pelvic inclination angle measurements were performed. Oswestry Disability Index was used to evaluate low back pain. The subjects with and without pes planus were compared. Results: There were no significant differences between the subjects with and without pes planus regarding tibialis posterior and peroneal muscle strength, gastrocnemius, soleus and hamstring muscle shortness, Q angle, American Orthopaedic Foot and Ankle Society score, and Visual Analogue Scale Foot and Ankle score (p>0.05). The pelvic inclination angle of the non-dominant side was higher (p=0.042), and Oswestry Disability Index score was higher (p=0.001) in subjects with pes planus compared to those without pes planus. Conclusion: Our results indicated that pes planus may increase pelvic inclination and may cause low back pain, while lower extremity muscle strength, muscle shortness, and foot function were not affected from this case in young sedentary subjects.

    Investigation of the validity and reliability of the 3-meter backward walk test in high functional level adults with lower limb amputation
    (Wolters Kluwer Health, 2024) Yildirim Sahan, Tezel; Aydogan Arslan, Saniye; Soyler, Osman
    Background: Backward walk training has an important place in the rehabilitation programs of lower extremity amputees. Objective: This study aimed to investigate the test-retest validity and reliability of the 3-meter backward walk test (3MBWT), minimal detectable change, and the cutoff time in high functional level adults with lower limb amputations (LLAs). Adults with LLA (n = 30) and healthy adults (n = 29) were included in the study. Study design: This is a randomized cross-sectional study. Methods: The Modified Fall Efficacy Score, Rivermead Mobility Index, and Timed Up and Go test with the 3MBWT were used to evaluate the concurrent validity of the test. The second evaluation (retest) was performed by the same physiotherapist 1 week following the first evaluation (test). The validity was assessed by correlating the 3MBWT times with the scores of other measures and by comparing the 3MBWT times between adults with LLA and healthy adults. Results: Test-retest reliability of the 3MBWT was excellent. The intraclass correlation coefficient for the 3MBWT was 0.950. The standard error of measurement and minimal detectable change values were 0.38 and 0.53, respectively. A moderate correlation was found between the 3MBWT, Modified Fall Efficacy Score, Timed Up and Go test, and Rivermead Mobility Index (p < 0.001). Significant differences in the 3MBWT times were found between adults with LLA and healthy controls (p < 0.001). The cutoff time of 3.11 s discriminates healthy adults from high functional level adults with LLA. Conclusions: The 3MBWT was determined to be valid, reliable, and easy-to-apply tool in high functional level adults with LLA. This assessment is a useful and practical measurement for dynamic balance in high functional level adults with LLA.

    The Cutoff Value of the Calf-Raise Senior Test for Older Faller
    (Routledge Journals, Taylor & Francis Ltd, 2020) Abit Kocaman, Ayse; Demirci, Cevher; Aydogan Arslan, Saniye; Yildirim Sahan, Tezel; Vergili, Ozge; Oral, M. Ayhan; Bezgin, Sabiha
    Aims The aim of this study is to determine a cutoff value of the calf-raise senior test and dual-calf-raise senior test according to fall history. Methods 150 elderly individuals participated in descriptive study. Berg Balance Scale (BBS), Timed Up and Go Test (TUG), Functional Reach Test (FRT), Calf-Raise Senior Test (CRST) and Calf-Raise Senior Test with additional cognitive task (dual- CRST) were applied. Results It was found to be high correlation between CRST and the BBS ,medium with TUG, and high with FRT . It was found to be high correlation dual-CRST and the BBS,medium with the TUG and high with FRT. According to the fall history, the cutoff value for the CRST was found 18.3 repetitions and 11.5 repetitions for the dual-CRST. Conclusion The present study has contributed significantly to the literature in terms of determining the cutoff value for fall risk in the CRST and dual-CRS.
