Purpose: The aim of this study was to compare the biomechanical properties of 4 different biceps tenodesis techniques. Type of Study: Biomechanical experiment. Methods: Four groups of fresh sheep shoulders (28 total) with similar shape characteristics were used. Biceps tenodesis was performed using the following techniques: group I (n = 7), tunnel technique; group 2 (n = 7), interference screw technique; group 3 (n = 7), anchor technique; and group 4 (n = 7), keyhole technique. Each construct was loaded to failure and the groups were compared with respect to maximum load in Newtons and deflection at maximum load in millimeters. The results were statistically analyzed with 1-way analysis of variance, the Bonferroni post hoc test and the Student t test or the nonparametric Mann-Whitney U test. Results: The calculated average maximum loads were 229.2 +/- 44.1 N for the tunnel technique, 243.3 +/- 72.4 N for the interference screw, 129.0 +/- 16.6 N for the anchor technique, and 101.7 +/- 27.9 N for the keyhole technique. Statistical testing showed no statistically significant differences between groups 1 and 2, groups 3 and 4, or groups 2 and 3 with respect to maximum load and deflection at maximum load (P =.09/P = .49, P =.41/P =.79, and P =.06/P =.82 for load/deflection in the 3 comparisons, respectively). However, all other group comparisons revealed significant differences for both parameters (group 1 nu group 4 [P < .01/P < .01]; group 1 nu group 3[P < .01/P =.01]; and group 2 nu group 4 [P =.007/P =.003]). Conclusions: The strongest construct was made with the interference screw technique, followed by the tunnel, anchor, and keyhole techniques. There were no statistically significant differences between the interference screw and tunnel techniques with respect to maximum load or deflection at maximum load. Clinical Relevance: Although it is difficult to extrapolate in vitro data to the clinical situation, the interference screw technique has better initial biomechanical properties and may produce improved clinical outcomes.

Master Plans for Pedestrian and Bicycle Transportation: Community Characteristics Severcan, Yücel Can; Levinger, David; Perry, Cynthia; Carter, Louise; Eyler, Amy; Aytur, Semra; Cradock, Angie L. I.; Evenson, Kelly R.; Heinrich, Katie; Kerr, Jacqueline; Litt, Jill; Severcan, Yucel; Voorhees, Carolyn (Human Kinetics, 2010-03-01) Background: Recent research demonstrates the importance of targeting the built environment to support individual physical activity, particularly for people experiencing health disparities. Master plans to promote biking and/or pedestrians (BPMPs) are a potential method for environmental change. This descriptive study aims to provide a snapshot of plan attributes and better understand demographic, social and transportation characteristics of communities with BPMPs. Methods: We collected a census sample of BP...
Dynamic function of the fibula. Gait analysis evaluation of three different parts of the shank after fibulectomy: proximal, middle and distal BOZKURT, MURAT; Yavuzer, G; Tönük, Ergin; KENTEL, BEHZAT BAHADIR (Springer Science and Business Media LLC, 2005-12-01) The purpose of this case study was to investigate the dynamic features of fibular movement to gait pattern by analyzing the gait of individuals with three different parts of the fibula resected. Gait analyses revealed that proximal fibula resection impaired knee stability, whereas distal fibula resection disturbed ankle kinematics significantly. Except a mild secondary quadriceps weakness, middle fibula resection did not cause a significant biomechanical disturbance on gait.
Surgical repair of cartilage defects of the patella Atik, OS; Korkusuz, Feza (Ovid Technologies (Wolters Kluwer Health), 2001-08-01) The structure and biomechanical forces on the patellar joint challenges researchers to define an ideal method for resurfacing the patellar cartilage. The articular surface of the patella presents variability between individuals, and has various minor articulations that bear partial or total compressive, shear, and combined forces during movement. Surgical techniques for the repair of patellar cartilage defects have evolved from cumulative advances in basic science and technology. Such surgeries include the ...
Comparison of the Effects of Eccentric, Concentric, and Eccentric-Concentric Isotonic Resistance Training at Two Velocities on Strength and Muscle Hypertrophy Ünlü, Gürcan; ÇEVİKOL, CAN; MELEKOĞLU, TUBA (Ovid Technologies (Wolters Kluwer Health), 2020-02-01) Ünlü, G, Çevikol, C, and Melekoğlu, T. Comparison of the effects of eccentric, concentric, and eccentric-concentric isotonic resistance training at two velocities on strength and muscle hypertrophy. J Strength Cond Res 34(2): 337–344, 2020—The aim of this study was to compare the effects of concentric, eccentric, and eccentric-concentric isotonic resistance training at both fast and slow velocities to determine whether contraction modality affects muscle strength and hypertrophy.

Impact of Social-Ecologic Intervention on Physical Activity Knowledge and Behaviors of Rural Students CENGİZ, CEVDET; İnce, Mustafa Levent (Human Kinetics, 2014-11-01) Background: The purpose of the study was to determine the effects of a social-ecologic intervention on health-related fitness (HRF) knowledge and behaviors of students (n = 62) living in rural areas. Methods: A prepost test control group design was constructed. In addition, qualitative data were collected by focus group discussions in the experimental group. Physical activity environment of a middle school was changed based on the social-ecologic model (SEM) with a focus on intrapersonal, interpersonal, com...
