Angst M. Load condition of the wrist during the forward handspring, the forward handspring with ulnar deviated hand positioning and the backward handspring. The range of motion between the two types of force application, constant and elastic resistance, is expected to show no difference. Effective marker placement for functional identification of the Centre of rotation at the hip. Comparison of the angles and corresponding moments in the knee and hip during restricted and unrestricted squats. Am J Public Health. Byram IR, Bushnell BD, Dugger K, Charron K, Harrell FE Jr, Noonan TJ. 1). Privacy Participants performed the exercises with a constant external load, or with an increasing external load due to its application via an elastic strap. Knorth H, Wittenberg RH, Dorfmüller P, Lebert R, Schmidt WE, Peskar BM, Wiese M, Heukamp M, Willburger RE. Therefore, rotator cuff muscles that are sufficiently strong and balanced are crucial for avoiding overload and averting shoulder pain/injury. Predictors of work-related repetitive strain injuries in a population cohort. For both CR and ER, the external loading at the end of the concentric movement phase corresponded to approximately 2% of the participant’s BM. During the Sho_int and Sho20_int exercises, adduction moments occurred throughout the whole repetition, while the other internal rotation exercises exhibited moments that switched from an adduction to an abduction, and back to an adduction moment again (Fig. Only the Sho_ext and Sho20_ext exercises exhibited different values for Mmax (only within CR) and for α(Mmax). Moments and angles were resampled over time, and moments were additionally normalized to BM. J Strength Cond Res. Am J Sports Med. These investigations were supplemented by histologic preparations. Exercises that train the muscles of the rotator cuff are recommended for not only preventing injuries, but also for rehabilitating the shoulder after injury, as well as part of whole-body strength training programmes [12]. Progressive resistance exercise in physical therapy: a summary of systematic reviews. The marker set consisted of 28 markers (Additional file 2: Figure S1), and aimed to ensure good marker visibility at all times, but also include a certain amount of redundancy in the marker cluster distributions [13, 22]. The mass and the centre of gravity for the upper arm, forearm, and hand, were determined according to Winter [34]. © 2020 BioMed Central Ltd unless otherwise stated. Upper pictures correspond to the starting point of the concentric phase, lower pictures to the end point of the concentric phase. All exercises started with the concentric phase first. In the course of our examinations we discovered a gliding mechanism of the subacromial bursa. Exercises found to change moment sign during the movement repetition should be selected with care, depending on the training goals, in order to focus on the intended target muscles and not their antagonists. Epub 2017 Jul 22. Positive values correspond to internal rotation, adduction, or flexion angles or moments (Table 2, Table 3). The contribution of the shoulder girdle to arm motion should not be neglected; therefore, the scapula and clavicula were modelled as a single segment (shoulder girdle). Furthermore, the joint angle at which the maximal moment occurred, α(Mmax), was generally achieved earlier in the concentric movement phase with CR than with ER. In the GHJC, the maximum external moment during internal rotation exercises, and the maximum internal moment, Mmax, during external rotation exercises were significantly higher when the exercise was performed with CR than when performed with ER (Tables 2 and 3). 2010;9(4):280–95. de Toledo JM, Ribeiro DC, de Castro MP, Forte FC, Korbes TS, Rusch MW, et al. Importantly, the GHJC, the elbow joint centre (EJC), elbow joint axis (EJA), and wrist joint centre (WJC) were all functionally determined [22] based on 9 different basic motion tasks (BMT; a full description is presented in the Additional file 3: Table S1). Following the back and knee, the shoulder is one of the most common sites for experiencing pain [1, 2], with shoulder injuries occurring in nearly all population groups [3,4,5]. Elbow and shoulder kinetics for 26 highly skilled, healthy adult pitchers were calculated using high-speed motion analysis. The shoulder joint kinetics that contributed to the differential racquet velocity profiles were mostly developed independent of wheelchair serve type, but varied with and were likely related to the level and severity of spinal cord injury of the individual players. Gait Posture. In vivo three-dimensional motion analysis of the shoulder joint during internal and external rotation. Solving problems in scientific computing using maple and Matlab. Here, improved access to shoulder joint motion and loading conditions could open perspectives for a greater understanding of rotator cuff strengthening exercises and their applicability for targeted training and rehabilitation. BMC Sports Sci Med Rehabil 10, 22 (2018). Seo CM, Kim K, Jeon A, Uhm CS, Lee JH, Han SH. In order to prevent fatigue during the exercise the selected load was lower compared to previous work [17]. More details about inclusion and exclusion criteria are presented in Table 1. Clin Biomech. BMC Musculoskelet Disord. The second hypothesis, assuming a difference of Mmax and α(Mmax) for the different exercises has been confirmed. 2015;16:210. 2010;13(6):803–9. 2018 Nov 6;2018:4535031. doi: 10.1155/2018/4535031. Here, it is important to note that in a non-orthogonal system, the sum of the 3 components do not represent the absolute moment. Koishi H, Goto A, Tanaka M, Omori Y, Futai K, Yoshikawa H, et al. 2005;85(11):1208–23. A method for determination of upper extremity kinematics. pulley, dumbbell, or barbell) or elastic resistance (ER) (e.g. The maximum internal/external moment, Mmax, was larger in exercises performed with CR than in those performed with ER, while α(Mmax) occurred earlier in the concentric movement with CR than with ER. The different moments are likely to have occurred due to different movement patterns in the two studies. Athletes, especially those who participate in overhead activities, place much stress on their shoulder joints during activity, so they are at increased risk for developing shoulder injuries. A study of the external forces and moments at the shoulder and elbow while performing every day tasks. Internal and external rotation exercises performed by the participants using CR and ER. The biomechanical assessment of these exercises is important for the establishment of evidence based guidelines; however, only sparse research has been performed in this area. The joint angles are defined the follows: int(+)/ext. Hence, in order to train over large RoMs with suitable loads, working with a variable resistance machine should be considered in order to maintain the RoM (Peltonen et al., 2012). Clin Orthop Relat Res. de Toledo JM, Loss JF, Janssen TW, van der Scheer JW, Alta TD, Willems WJ, et al. Two critical instants were 1) shortly before the arm reached maximum external rotation, when 67 N-m of Comput Methods Biomech Biomed Eng. (PDF 161 kb), The marker set for a right-handed participant is shown with the joint coordinate systems. FS: data evaluation and writing of the manuscript. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Kratzenstein S, Kornaropoulos EI, Ehrig RM, Heller MO, Popplau BM, Taylor WR. All valid trials were analysed and no outliers were removed evaluation of the measured data. In the wheelchair propulsion literature it is common to report upper extremity joint kinetics as a means to express the load being experienced by the shoulder, elbow and wrist. When the exercises were performed with ER, the maximum load was always reached at the end of the concentric movement. A total of 28 markers were used to model the following segments: torso, shoulder girdle, upper arm, forearm, and hand. c Normalized internal/external rotation moments [Nm/kg] as a function of the internal/external rotation angles [°] are shown for external rotation exercises of the shoulder. Biomed Res Int. Springer Nature. Med Biol Eng Comput. As a result, it would seem to be important for therapists to carefully increase the load with progressive rehabilitation so that the patients are still able to maintain a large RoM during the exercises. The second goal of the present study was to design a marker set for functional joint centre determination of the shoulder joints to be able to examine upper extremity kinetics and kinematics in 3D of the selected shoulder strength exercises. Moreover, the resultant peak moments during exercises performed with ER appeared to be smaller than those achieved when exercising with dumbbells [17]. pulley system) at loads higher than 50% of the one repetition maximum has been shown to significantly decrease the RoMs in the GHJC compared to that with lower loads [16]. Clin Biomech.  |  The mass of the handle was 0.047 kg and its centre of gravity was assumed to be the same as that for the hand. This unique function is essential at the shoulder to enable the hand to be placed in the multitude of … Clin Biomech (Bristol, Avon). Joint moments and angles in the GHJC: a Normalized internal/external rotation moments [Nm/kg] as a function of the internal/external rotation angles [°] are shown for internal rotation exercises of the shoulder. Preseason shoulder strength measurements in professional baseball pitchers: identifying players at risk for injury. if the abduction muscles need to be strengthened, internal rotation exercises should be chosen with caution as they lead to both agonistic and antagonistic loading in the GHJC and therefore train adduction muscles rather than abduction muscles over at least part of the movement.
