Article Measuring Shoulder Abduction Strength Using 2 Different Dynamometers: Comprehensive Intrarater and Interrater Reliability and Validity(Turkish Assoc Orthopaedics Traumatology, 2025) Atli, Ecenur; Topaloglu, Mahir; Hosbay, Zeynep; Ozdincler, Arzu RazakObjective: The purpose of this study is to investigate the intrarater and interrater reliability of handheld dynamometer (HHD) measurements in assessing isometric muscle strength of the shoulder abductors and to compare these results with those obtained using a fixed dynamometer (FD). Methods: The study involved 25 voluntary participants, all over the age of 18, asymptomatic (with no injuries in the upper extremity), and not engaged in overhead sports. The participants were evaluated twice by 2 different testers who were experienced in orthopedic rehabilitation, at 90 degrees of shoulder abduction in the scapular plane. On the first measurement day, Tester 1 performed measurements using both HHD and FD, while on the second measurement day, both testers used only the HHD. A 3-to 7-day interval separated the 2 measurement sessions. Paired-samples t-tests were used to evaluate the systematic bias between the testers. Spearman's rank correlation coefficient, intraclass correlation coefficient, standard error of measurement, and minimal detectable change were calculated. The statistical significance level was accepted as P < .05. Results: Data from 22 participants (15 women, 7 men; mean age: 23.00 +/- 3.19 years) were analyzed, as 3 individuals did not attend the final assessment. A strong correlation (r = 0.772) was found between Tester 1's HHD measurements and FD, while a similarly strong correlation (r = 0.748) was observed for Tester 2's HHD measurements. Excellent intrarater reliability (intraclass correlation coefficient [ICC]= 0.941) was found between Tester 1's measurements, and excellent interrater reliability (ICC= 0.889) was found between testers. Conclusion: Handheld dynamometer has demonstrated excellent interrater and intrarater reliability and high validity for assessing shoulder abductor muscle strength in research and clinical use. Since the muscle strength of testers using the HHD may influence the results, the FD may be a more appropriate option when the study population is stronger than the testers. Studies involving different clinical populations and testers with varying experience levels are needed to improve the relevance of the results. Level of Evidence: Level III, Diagnostic Study.Article Citation - WoS: 4Citation - Scopus: 4Is Plantar Foot Sensation Affected in Patients With Gonarthrosis(Turkish Assoc Orthopaedics Traumatology, 2021) Tascilar, Lacin Naz; Utlu, Defne Kaya; Sayaca, Cetin; Polat, Gokhan; Kuyucu, Ersin; Erdil, Mehmet Emin; Utlu, Prof.dr. Defne KayaObjective: The aim of this study was to compare pain, plantar foot sensation, postural control, fear of movement, and functional level between women patients with early-stage gonarthrosis and those with late-stage gonarthrosis. Methods: A total of 62 women with gonarthrosis were included in the study. Patients were then divided into two groups: early-stage gonarthrosis group (31 women) and late-stage gonarthrosis group (31 women) according to Kellgren Lawrence criteria. Light touch-pressure sensation (Semmes Weinstein Monofilaments), two-point discrimination sensation (esthesiometer), and vibration sensation (128 Hz diapason) were used to evaluate plantar foot sensation. Pain intensity was assessed by the numeric rating scale, postural control by Berg balance scale, fear of movement by the Tampa kinesiophobia scale, functional mobility by the Timed Up and Go test and knee injury and osteoarthritis outcome score. Results: Early-stage patients were found to have higher light-touch pressure sensation on 1st metatarsal head of dominant side, 5th metatarsal head of non-dominant side, heel of non-dominant side than late stage patients. Early-stage patients had a higher sensation of vibration than late stage patients. The patients in the early stage were found to have higher two-point discrimination sensation on middle of dominant side, heel of dominant side, trans-metatarsal of non-dominant side, middle of non-dominant side, heel of non-dominant side than late stage. Postural control of early-stage patients were found to be higher than late-stage patients. Early-stage patients had lower kinesophobia and higher functional levels than late-stage patients. Conclusion: The light touch sensation, vibration sensation, and two-point discrimination deteriorated by the progression of the disease should be important criteria in patients with gonarthrosis.Article Citation - WoS: 1Time Difference Between Onsets of Lateral and Medial Hamstring Muscles During Gait in Patients With Patellofemoral Pain: a Preliminary Study(Marmara Univ, inst Health Sciences, 2022) Coskunsu, Dilber Karagozoglu; Can, Filiz; Kuchimovs, Shavkat; Akalan, Nazif Ekin; Kilicoglu, I. Onder; Ozturk, Necla; Kuchimov, Shavkat; Kılıçoğlu, Önder İsmetObjective: Early activation of lateral hamstrings (LH) relative to medial hamstrings (MH) has been thought to be the cause of abnormal knee abduction and external rotation of the tibia, which affects the orientation of patellar tendon and increases lateral patellofemoral compression. Therefore, early activation of LH relative to MH is considered to have a role in the patellofemoral pain (PFP). The aim of this study was to investigate the time difference between MH and LH onsets in patients with PFP during gait. Methods: Thirteen patients with bilateral PFP (mean age 28.73 +/- 7.44 years) and 13 asymptomatic subjects (mean age 30.47 +/- 6.22 years) were recruited in the study. Gait analysis was performed using the ELITE system (BTS, Milano-Italy) with video cameras (TVC, BTS, Milano-Italy). Participants were requested to walk at a self-selected speed on a force platform, and EMG data were recorded from MH and LH muscles for 10 initial contacts by using TELEEMG (BTS, Milano-Italy). Time difference between the onsets of the MH and LH was calculated for each initial contact by using moving averaging method, then their mean was obtained for each participant. Results: The time difference between onsets of MH and LH was - 26.9 +/- 22.2 ms for PFP subjects and - 11.2 +/- 14.2 ms for control subjects, and LH mainly became activated earlier compared to MH in most of the subjects in both groups. There was a statistically significant difference between the time differences of the groups (p=0.041). Conclusion: Our findings suggest that LH displayed an earlier activation in subjects with PFP compared to control subjects during gait.
