Publication Acute effects of static stretching and massage on flexibility and jumping performance(Jmni, 2020-12-01) Yıldız, Suat; Gelen, Ertuğrul; Çilli, Murat; Karaca, Hasan; Kayıhan, Gürhan; Özkan, Ali; Sayaca, Çetin; SAYACA, ÇETİN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Fiziksel Tıp ve Rehabilitasyon Anabilim Dalı.; 0000-0002-6731-1677; AAG-7644-2021Objective: The purpose of this study was to evaluate the effects of static stretching and the application of massage on flexibility and jump performance. Methods: Thirty-five athletes studying Physical Education at University (mean age 23.6 +/- 1.3 years. mean height 177.8 +/- 6.3 cm and mean weight 72.2 +/- 6.7 kg) performed one of three different warmup protocols on non-consecutive days. Protocols included static stretching ISS). combined static stretching and massage [SSW, and neither stretching nor massage [CONT]. The athletes performed flexibility, countermovement jump (CMJ) and squat jump (SJ) tests. Results: SS and SSM protocols demonstrated 12%(p<0.05) and 16% (p<0.05) respectively greater flexibility than the CONT protocol. SJ and CMJ performances were significantly decreased 10.4% (p<0.05) and 5.5% (p<0.05) respectively after the SS protocol. There was no significant difference between SSM and CONT protocol in terms of SJ and CMJ performance. Conclusion: This research indicates that whereas static stretching increases the flexibility it decreases the jumping performance of the athletes. On the other hand. the application of massage immediately following static stretching increases flexibility but does not reduce jumping performance. Considering the known negative acute effects of static stretching on performance. the application of massage is thought to be beneficial in alleviating such effects.Publication Scapular dyskinesis, shoulder joint position sense, and functional level after arthroscopic bankart repair(Sage Publications, 2021-08-01) Unal, Miray; Ozenci, A. Merter; Sayaca, Cetin; SAYACA, ÇETİN; Calik, Mahmut; Eyuboglu, Filiz Erdem; Kaya, Defne; KAYA UTLU, DEFNE; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Fakültesi.; AAG-7644-2021; GQH-1570-2022; KCY-7189-2024Background: Scapular kinesia is an important component of glenohumeral rhythm and shoulder stability. No studies have evaluated scapular dyskinesis and its relationship to shoulder proprioception in patients who have undergone arthroscopic Bankart repair (ABR). Purpose: To investigate scapular dyskinesis, proprioception, and functional level after ABR. Study Design: Cohort study; Level of evidence, 3. Methods: This study included 13 male patients who underwent ABR (ABR group; mean age, 30 years; range, 24-36 years) and 13 sex- and age-matched healthy individuals (control group). The age, height, weight, and dominant side of all participants were collected. Scapular dyskinesis was evaluated using the lateral scapular slide test and the scapular dyskinesis test; proprioception was measured by the active angle reproduction test using a smartphone goniometer application, and functional level was assessed using the upper-quarter Y-balance test for dynamic stability as well as the Rowe score and Walch-Duplay score for quality of life and return to activities of daily living. Results: The presence of static scapular dyskinesis in the neutral position, at 45 degrees of abduction, and at 90 degrees of abduction as well as the presence of dynamic scapular dyskinesis was higher in the ABR group compared with the control group (P <= .04 for all). Shoulder joint position sense (absolute error) at 40 degrees and 100 degrees of shoulder elevation and shoulder functional level according to the Rowe score were worse in the ABR patients compared with the healthy controls (P <= .02 for all). Dynamic scapular dyskinesis was negatively related to shoulder joint position sense at 40 degrees of shoulder elevation (r = -0.64; P = .01). Static scapular movement as measured on the lateral scapular slide test was moderately related to the Rowe score (r = 0.58; P = .03). Conclusion: Scapular kinematics and proprioception should be evaluated after ABR. Treatment approaches to improve scapular control and proprioceptive sense should be included in the rehabilitation program for patients after ABR.Publication Shoulder joint position sense in thoracic outlet syndrome(Edra Spa, 2021-01-01) Sayaca, C.; Eyuboglu, F.; Calik, M.; Guney-Deniz, H.; Firat, T.; Sayaca, C.; SAYACA, ÇETİN; Kaya, D.; KAYA UTLU, DEFNE; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Fakültesi.; 0000-0002-6731-1677; AAG-7644-2021Objective. The aim of the study was to analyze joint position sense (JPS), and muscle strength & endurance in patients with Thoracic Outlet Syndrome (TOS).Methods. Eight patients with unilateral TOS and eight healthy controls participated. Pain, symptom duration, JPS, and strength&endurance were evaluated.Results. There was a difference in Absolute Error (AE) of the abduction at 70 degrees (p =0.02). There were differences in AE at 40 degrees (p =0.01) and 130 degrees (p =0.04) abduction between the affected side of patients and the dominant side of the healthy group. Additionally, the pain was related to poor Relative Error at 90 degrees abduction and AE at 130 degrees flexion (p = 0.01). There was no difference in strength and endurance of flexion (p > 0.05) and abduction (p > 0.05) to compare the affected and unaffected side of the patients with TOS. There were differences strength of flexion (at 60 degrees/sec; p = 0.05), strength of abduction (at 60 degrees/sec; p = 0.01), and endurance of abduction (at 180 degrees/sec; p = 0.05) to compare affected side of patients with TOS and healthy person.Conclusions. This study indicated that JPS was decreased at 40 degrees & 70 degrees & 130 degrees abduction, strength in flexion and abduction was also decreased. Proprioceptive and strengthening exercises should be considered to implement in patients with TOS.
