kinetics of shoulder joint

The applied external load was measured with a load cell placed in series with the external resistance, and moments were calculated using an inverse dynamics approach. Working with a CR (e.g. This anatomic study was devoted to the kinetics of the shoulder joint and especially the subacromial region. SL: design of the study, evaluation of the data, writing of the manuscript. Joint angles for every joint were calculated using the Joint Coordinate System (JCS) convention [33], for details please see (Additional file 2: Figure S1 and Additional file 1 “Definitions of the joint coordinate systems”). Lovern B, Stroud LA, Evans RO, Evans SL, Holt CA. Schellenberg F, Lindorfer J, List R, Taylor WR, Lorenzetti S. Kinetic and kinematic differences between deadlifts and goodmornings. Elbow and shoulder kinetics for 26 highly skilled, healthy adult pitchers were calculated using high-speed motion analysis. In our study, various CRs resulted in higher internal and external joint moments in the GHJC compared with exercises using ER, and as a result, the corresponding muscles will be trained more when using CR. In the GHJC, the adduction/abduction Mmax was not significantly different between the CR and ER configurations (Table 2 and 3). Muscle activation and perceived loading during rehabilitation exercises: comparison of dumbbells and elastic resistance. 2009;223(7):823–31. 5-2 #Shoulder joint is a complex joint composed of clavicle,scapula & humerus. The analysis was limited to movements and kinetics of the glenohumeral joint because of the difficulties in measuring the positions of the scapula, clavicle, and thoracic spine movement during propulsion. During training and in the fields of injury prevention and rehabilitation, exercises addressing the internal and external rotator muscles of the shoulder are generally either performed using constant resistance (CR) (e.g. California Privacy Statement, shoulder kinetics and kinematics during internal and ex-ternal rotation exercises performed with CR or with ER. 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. 1). 2010;13(6):803–9. pulley, dumbbell, or barbell) or elastic resistance (ER) (e.g. Schellenberg F, Schmid N, Haberle R, Horterer N, Taylor WR, Lorenzetti S. Loading conditions in the spine, hip and knee during different executions of back extension exercises. 2005;85(11):1208–23. Google Scholar. 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. J Strength Cond Res. All calculations were performed using MATLAB (version R2014a, MathWorks, Natick, MA, USA). Position and orientation of the segments were determined using a least-squares fit of the corresponding marker clusters [32]. Variability in attachment of the coracoacromial ligament in relation with its morphology. In particular, Sho_int and Sho20_int might not be appropriate for rehabilitation, as they result in adduction moments rather than the expected abduction moments, and to internal rotation moments over part of the movement in addition to the expected external rotation moments. Therefore, the loading motion patterns identified in this study can help to choose suitable shoulder exercises dependent on the training objective. To the authors’ knowledge, the present study is the first to examine the RoMs and corresponding joint moments in the upper extremities during internal and external rotation exercises of the shoulder, performed using CR and ER. (PDF 161 kb), The marker set for a right-handed participant is shown with the joint coordinate systems. All participants performed eight repetitions of ten exercises using their dominant arm for coordination-based tasks, for which arm position and direction of the external force was varied. Man Med. Further research is clearly required to investigate whether an additional rotation of the arm or different angle of the load application is required in these exercises in order to enhance the desired muscular loading over a large RoM. Berlin: Springer; 1997. p. 339–49. models have a substantial influence on the kinematics and kinetics of the pitchers. The authors declare that they have no competing interests. J Orthop Res. 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. 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]. 2005;331(7525):1124–8. Defined parameters of interest were: RoM, maximum moment (Mmax), and the angle at which Mmax occurred (α(Mmax)). For the development of optimal training recommendations, the kinematic and kinetic nature of the specific exercises and training devices must be considered [13,14,15]. In order to prevent fatigue during the exercise the selected load was lower compared to previous work [17]. This site needs JavaScript to work properly. For the GHJC, the flexion/extension axis was defined to be the floating axis (FL), as this was the axis of least importance for the examined movements. Furthermore, a deficit in rotator cuff strength, or an imbalanced muscular strength profile in the rotator cuff, is known to be associated with an increased risk of shoulder problems in various sports [8,9,10,11]. The kinematics and kinetics of 12 participants while they performed 10 different exercises with a constant and with an elastic external load corresponding to 2% body mass was assessed. Rettig O, Fradet L, Kasten P, Raiss P, Wolf SI. 2009;47(5):543. Baechle TR, Earle RW. Previous researchers have linked elbow and shoulder injuries to a variety of risk factors, including pitch volume, 23,24 increased innings pitched in a calendar year, 23,25 increased body mass, 23 pitch type, 24,26,27 and number of months pitched per year. Hand markers had a diameter of 9 mm while the remaining markers had a diameter of 14 mm. A pulley-like system was used to apply the CR, whereas a progressive resistance strap (yellow TheraBand®) was used for ER (Fig. Shoulder joint kinetics Moments about the axes of internal/external rotation and adduction/abduction were very low to null (<0.2%BW⋅AL), whereas moments about the flexion/extension axis were much higher (Fig. In order to achieve a high training effect, strengthening exercises should be performed over the entire RoM [36].

All valid trials were analysed and no outliers were removed evaluation of the measured data. Effects of different technical coordinate system definitions on the three dimensional representation of the glenohumeral joint Centre. Changes in the joint moments between ER and CR indicate that the resultant Mmax should be taken into account when selecting the appropriate resistance type.

BMC Sports Sci Med Rehabil. NLM However, if an external rotation exercise is performed with the arm abducted to 90°, the direction of the external force must be chosen carefully. Knorth H, Wittenberg RH, Dorfmüller P, Lebert R, Schmidt WE, Peskar BM, Wiese M, Heukamp M, Willburger RE. Alraddadi A, Alashkham A, Lamb C, Soames R. Surg Radiol Anat. This study was conducted at the Institute for Biomechanics, ETH Zurich, Zürich Switzerland. Description of the coordinate systems. (TIF 4823 kb), Table S1. In biomechanical research, the 3D assessment of segmental motion based on skin markers is limited by soft tissue artefact [21], as well as marker visibility, marker cluster distribution, number of markers per segment, and positioning of the markers [13, 22, 23]. Biomechanics of human movement. 2012;36(3):482–6. Preseason shoulder strength measurements in professional baseball pitchers: identifying players at risk for injury. Participants performed the exercises with a constant external load, or with an increasing external load due to its application via an elastic strap. Gait Posture. With the aim to establish exercise regimes that are able to provide high joint moments throughout a large rotational RoM for the rotator cuff muscles, the goal of the present study was therefore to examine upper extremity kinetics and kinematics in 3D for five internal and five external rotation exercises. Please enable it to take advantage of the complete set of features! The second hypothesis, assuming a difference of Mmax and α(Mmax) for the different exercises has been confirmed. Basic motion tasks. Clin Biomech. We compared the model to “gold standard” bone-pin kinematics collected during three shoulder tasks and found modeled scapular kinematics to be accurate to within 2mm root-mean-squared error for individual bone-pin markers across all markers and movement tasks. Proc Inst Mech Eng H J Eng Med. a handle, b load cell, c 3 markers for the determination of the direction of the external force, d external force, e height adjustable pulley, f water container for adjusting the weight, g one of the ten Vicon cameras, HCR) constant external resistance – could be replaced with HER) elastic external resistance. The fixed and random effects coefficients of the linear mixed model are included in the Additional files section (Additional file 3: Tables S2-S4). Silvio Lorenzetti. 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. Therefore, interpretation of the flexion/extension angles in the GHJC must be treated with caution, and if other movements in the shoulder joint are to be examined, the JCS may need to be defined differently. Differences are seen for individuals and for the subjects as a group. The maximum external moment, Mmax, in Sho20_com, Elb_int, and Elb20_int exercises occurred during the first half of the concentric phase of the movement when performed with CR, but occurred later in the movement when performed with ER (Fig. Gait Posture. Shoulder pain: diagnosis and management in primary care. 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. Since upper-body marker sets remain challenged by these issues, a suitable marker set for the shoulder is clearly required [20, 24,25,26,27,28]. WRT: data evaluation and writing of the manuscript. In the course of our examinations we discovered a gliding mechanism of the subacromial bursa. No statistical analysis was performed for the RoMs in the SCJC, but maximal RoMs were achieved during the Sho20_com exercise performed with ER and the Elb20_com exercise performed with CR, which reached up to 16.9 ± 3.5° for internal/external rotation, 22.7 ± 4.7° for adduction/abduction, and 13.3 ± 5.0° for flexion/extension.

A statistical analysis of the SCJC was not performed. During the Sho20_com and Elb20_com exercises, the RoMs for internal/external rotation and adduction/abduction were significantly higher than those for all other internal and external rotation exercises (Table 2, Table 3). BMC Musculoskelet Disord. Campbell AC, Alderson J, Lloyd D, Elliott B. However, the maximal moments observed, as well as the angles of the maximal moments are assumed to differ between the selected exercises. J Biomech. Hingtgen B, McGuire JR, Wang M, Harris GF. In vivo three-dimensional motion analysis of the shoulder joint during internal and external rotation. Another limitation of this study is, that the here used marker set has not been directly validated with a gold standard such as MRI. Positive values correspond to internal rotation, adduction, or flexion angles or moments (Table 2, Table 3). eCollection 2018. Springer Nature. 2017;9:10. This effect was considered to occur because the weight of the arm inducing a moment in the GHJC was too high to be fully compensated by the small external forces (approx. Progressive resistance exercise in physical therapy: a summary of systematic reviews. Exercises began with the concentric phase of the movement. The task of choosing the appropriate kinetic resolution coordinate system for upper extremity joint forces and moments has shown itself to be a lab-specific process. It is important to note that the joint moments for Sho_int and Sho20_int exercises changed from an external rotation moment to an internal rotation moment and back again during the exercise execution (Fig. All exercises are performed using two types of force application methods, including constant and elastic resistance. 3a). *: Starting point of the concentric phase of the movement. However, the higher complexity of the combined movements needs more cautious interpretation due to gimbal lock, limited clinical interpretability and dependency of resulting joint motion on the choice of mathematical convention for joint angular description. Müller R, Brügger O. Fitness-Center: Verletzungen und Beschwerden beim Training. Grood ES, Suntay WJ. 2004 Jul-Aug;13(4):454-8. doi: 10.1016/j.jse.2004.02.001. 1). If, for instance, internal rotation muscles should be trained, Elb_int or Elb20_int would be reasonable choices, as these exercises show a good trade-off between the examined parameters. Cole DC, Ibrahim S, Shannon HS. A total of 28 markers were used to model the following segments: torso, shoulder girdle, upper arm, forearm, and hand. The most common shoulder problem is related to injury to the rotator cuff [6, 7]. The internal/external rotation angle at which the maximal moment Mmax occurred, α(Mmax), was significantly different between the two resistance types for all exercises except for Sho_int (p = 0.396) and Sho20_int (p = 0.794) (Table 2 and 3). ISB recommendation on definitions of joint coordinate systems of various joints for the reporting of human joint motion--part II: shoulder, elbow, wrist and hand. Gander W, Hrebicek J. Therefore, as expected in the first part of our hypothesis, the RoM did not differ significantly between the two resistance types. elastic straps or tubes). All statistical analyses were performed using SPSS software (version 22, IBM). Moments and angles were resampled over time, and moments were additionally normalized to BM. We termed this the coracoid aponeurosis, which facilitates gliding behaviour of the shoulder joint capsule beneath the coracoid process. Clarsen B, Bahr R, Andersson SH, Munk R, Myklebust G. Reduced glenohumeral rotation, external rotation weakness and scapular dyskinesis are risk factors for shoulder injuries among elite male handball players: a prospective cohort study. The largest RoMs in the GHJC were observed during the Sho20_com and Elb20_com exercises. Koishi H, Goto A, Tanaka M, Omori Y, Futai K, Yoshikawa H, et al. Knowledge about the motion and loadings of the upper extremities during these exercises is crucial for the development of optimal training recommendations. Kinesio Tape may negatively affect shoulder joint position sense, especially as the shoulder position approaches 90 of elevation. The external constant load was adjusted to 2% of the participant’s BM by adding or removing water mass. Recent research has assessed the effect of different technical coordinate system definition on the three dimensional representation of the glenohumeral joint center [29]. The person on the picture has provided written consent for publication. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. In contrast, Sho_ext and Sho20_ext exercises differed in internal Mmax with CR, and in the internal α(Mmax) with both CR and ER (Table 3). 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. J Biomech. More details about inclusion and exclusion criteria are presented in Table 1. By using this website, you agree to our b Normalized adduction/abduction moments [Nm/kg] as a function of the adduction/abduction angles [°] are shown for internal rotation exercises of the shoulder. Fixed effects coefficients and standard error. Byram IR, Bushnell BD, Dugger K, Charron K, Harrell FE Jr, Noonan TJ. However, as the shoulder complex consists of three joints that all contribute to the total motion of the arm, it is clear than more than one joint should be investigated simultaneously. The force data, measured by the load cell, were filtered using a 3rd order low-pass Butterworth filter and its direction was determined using three markers that were placed in series with the resistance cord and the load cell (Fig. Shoulder joint kinetics that characterise the WFS and WKS As in able-bodied serves, homogeneous and negligible peak external rotation moments assisted external rotation of the upper arm during the “cocking” phase of the WFS and WKS. Five of the exercises are designed to train the internal rotator muscles of the shoulder (Elb_int, Elb20_int, Sho_int, Sho20_int, Sho20_com), and five the external rotator muscles (Elb_ext, Elb20_ext, Sho_ext, Sho20_ext, Elb20_com) (Fig. J Electromyogr Kinesiol. Comparison of shoulder resultant net moment between three different exercises and load conditions. 2012;22(3):424–30. Andersen LL, Andersen CH, Mortensen OS, Poulsen OM, Bjornlund IB, Zebis MK. The handball throw is characterized by large external shoulder rotation followed by a rapid internal rotation with minor changes in shoulder flexion and abduction. Shoulder joint related problems are a common reason for visits to the Orthopaedic surgeon. This unique function is essential at the shoulder to enable the hand to be placed in the multitude of … Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made. 1998;57(11):649–55. The adduction/abduction angle, α(Mmax), was not significantly different between CR and ER (internal and external rotational exercises p = 0.935 and p = 0.919, respectively) (Table 2 and 3). Am J Sports Med. Dynamic tracking of the scapula using skin-mounted markers. 2013;51(6):468–72. Depending on the desired RoMs, different exercises can be chosen. No differences in the examined parameters were observed between Elb_int and Elb20_int, between Sho_int and Sho20_int, or between Elb_ext and Elb20_ext exercises. In contrast, Mmax and α(Mmax) can be altered by the choice of the resistance type. 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. Six female and six male participants, all healthy and with experience in weight training (average age 24.9 ± 5.8 years; weight 68 ± 13 kg; height 1.76 ± 0.08 m) were recruited to participate in this study. Only the Sho_ext and Sho20_ext exercises exhibited different values for Mmax (only within CR) and for α(Mmax). Arthroscopy. Clipboard, Search History, and several other advanced features are temporarily unavailable. Privacy The range of motion in the glenohumeral joint did not differ significantly between the two resistance types, whereas internal/external rotation moments were significantly higher with constant resistance than those with elastic resistance. 2011 Apr;27(4):556-67. doi: 10.1016/j.arthro.2010.10.004. 2016 Jan;44(1):191-7. doi: 10.1177/0363546515608652. Clin Orthop Relat Res. Ann Rheum Dis. 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. At the glenohumeral joint, compressive force, joint laxity, and 380 N of anterior force during arm cocking can lead to anterior glenoid labral tear. Therefore, rotator cuff muscles that are sufficiently strong and balanced are crucial for avoiding overload and averting shoulder pain/injury. In fitness centres, the shoulder is the most common site of injury (24.4%), mainly due to overloading (45.6%) and incorrect exercise execution (21.1%) [5]. 03 ) 00047-0 positions and direction of the complete set of features, Table 3.!
