Biomechanical analyses are capable of capturing and evaluating human motions. In addition to the major biomechanical fields of kinetics and kinematics, electromyography (EMG) provides a reliable way to analyse neuromuscular activities, e.g. inter- and intramuscular coordination or fatigue behavior. Based on these parameters it is possible to conclude to clinically relevant parameters such as motor control, muscular coordination or compensation strategies with different loads. In addition to this, EMG can be used in treatment itself, e.g. biofeedback-training with an EMG is an effective and evidenced based tool to improve neuromuscular control. The purpose of this workshop is to show the advantages of implementing EMG in performing artists´ health and to demonstrate additional therapy and diagnostic options.
This workshop briefly introduces the theoretical principles of EMG and the clinical applications in the context of performing artists´ health. It explains why EMG provides an additional value in the clinical reasoning process and supports the therapist, but decision making in the clinical reasoning process should never be based on EMG solely.
In the further course of the workshop the use of EMG in diagnostics and therapy (biofeedback) with performing artists is practically demonstrated and discussed with the participants.
Approach of Presentation:
1. Short presentation: introduction and understanding of EMG (educational objective 1)

Introduction: Hamstring injuries are among the most common injuries in soccer players. Especially the danger of hamstring injuries increases in the final third of each half, with the biceps femoris muscle being highly susceptible, but currently there is no supporting evidence in soccer players. It is important to investigate to provide a basis for further clinical investigations in order to reduce the risk of hamstring injuries.
Objective: To investigate a soccer-specific muscle fatigue protocol has an effect on the activation patterns of the biceps and semitendinosus muscles and correlates with the subjectively perceived exertion of the soccer players.
Methods: 19 healthy soccer players aged 19 - 35 years were included and underwent a standardized procedure that included: (1) performance of the nordic hamstring curls (NHC) and a 10m sprint (pre-test), (2) a soccer-specific muscle fatigue loading protocol for 30 minutes with subsequent rating of perceived exertion (RPE), (3) re-assessed like pre-assessment (post- test). Electromyography (EMG) data were recorded the biceps and
semitendinosus muscles of both legs. Two parameters were analyzed: the peak amplitude during the NHC and the mean amplitude during the 10m sprint.
Results: The RPE score (9.5, p<0.001) and 10m sprint shows significant differences between pre- and post- test for the biceps (standing leg: -82.45, kicking leg: -81.77; p<0.01) and semitendinosus muscle (standing leg: -60.08, p=0.001); kicking leg: -65.30, p=0.03). Significant correlation exists between RPE score and biceps muscles at posttest (standing leg: r=-0.54, kicking leg: r=-0.51; p<0.05).
Conclusion: Muscle fatigue leads to significant changes in the activation behavior of the hamstring muscles. In particular, the biceps muscle shows a correlation with perceived exertion, the higher the exertion, the lower the muscle activity. This may help explain the higher prevalence of the biceps muscle in hamstring injuries and offers a basis for further clinical investigations
Rationale
Playing the trombone can lead to playing-related musculoskeletal disorders (PRMD). Previous research suggests that professional trombonists predominantly struggle with PRMD on the left body side. An increasing volume leads to an increasing contact pressure on the mouthpiece of the trombone, but it is still unclear how the muscle activity relates to this and whether it differs in musicians with PRMD from those without PRMD.
Purpose
The purpose of this study was to investigate the relationship between the activity of different muscles of the left body side, the contact pressure on the mouthpiece and the volume level in healthy trombonists.
Methods
Six male healthy tenor trombonists were included in this study and run through a standardized protocol which consisted of playing a b-flat major scale with three different volume levels (pianissimo, mezzoforte, fortissimo). Analyzed parameters were (1) the activity of several muscles of the left body side (measured with surface electromyography), (2) the contact pressure on the mouthpiece (measured with a force sensor) and (3) the different volume levels.
Results
Analysis of variance reveals significant differences of the muscle activity for the three volume levels. Depending on the volume level and the selected muscle, results show very weak to moderate correlations between contact pressure on the mouthpiece and muscle activity (Spearman´s rho between .11 and .58). The strongest correlation across all muscles occurs during fortissimo playing.
Conclusions
These results show a relationship in healthy trombonists between volume level, contact pressure on the mouthpiece and muscle activity when playing a b-flat major scale. Future research should include trombonists with PRMD to enable comparison between PRMD and non-PRMD musicians.
Educational Objectives:
At the end of the presentation, the participants will be able to…
1. understand the relationship between muscle activity, contact pressure on the mouthpiece and volume when playing the trombone
2. recognize that there are different muscle activity patterns on the left body side when playing the trombone
3. understand that a comprehensive functional diagnosis is important in the management of musicians

Clinical Significance:
EMG based functional neuromuscular diagnostics and biofeedback-training provides both the therapist as well as the musician with additional value in their clinical work.
Rationale:
Performing artists are exposed to high strains during their performance. These strains are similar to the ones of professional athletes, but in contrast to athletes there is a comprehensive undersupply of care regarding preventive and rehabilitative therapy offers.
Purpose:
The purpose of RefLabPerform is to develop a reference laboratory for the assessment of neuromusculoskeletal disorders using physiotherapeutic assessment methods in combination with biomechanical motion analysis. This includes the automatized integration of the physiotherapeutic assessments with the technical biomechanical analysis for an individual treatment recommendation with decentralized health care recommendations for a home-based therapy based on evidence-based prevention and rehabilitation strategies.
Methods:
Several work packages are processed systematically, whereby according to the requirements in the course of the project an overlapping of work packages occurs. First, the component planning of the innovative reference laboratory structure is carried out, on which the clinical and technical development of the reference laboratory is based. The next steps are the development of individual clinical assessment protocols, prevention and rehabilitation strategies as well as the setup of the laboratory and the development of technical routines. Parallel to this, various analysis tools are being developed for biomechanical data as well as for physiotherapeutic diagnostics and merged at the end of this work package for individual results for different groups of performing artists. Overlapping with the previous work packages, the reference laboratory will be tested for application and manageability. Clinical and technical data are brought together and checked by means of individual case trials on various groups of artists. In terms of an agile software development process, the results flow back into the previous work packages in order to optimize them and then test them again.
Results:
At the end of the project a functional and proven reference laboratory for the comprehensive analysis of performing artists will be developed.
Conclusions:
This reference laboratory is specialized to the diagnosis and treatment of playing- and performance-related dysfunctions with a focus on clinical findings and biomechanical movement analysis.
Educational Objectives:
At the end of the presentation, the participants will be able to…
1. describe the innovative content of the project RefLabPerform
2. understand the advantages of merged analysis strategies by physiotherapeutic and biomechanical examinations
3. understand the complex interdisciplinary process to develop a reference laboratory for performing artists

Hintergrund
Das Bundesministerium für Bildung und Forschung (BMBF) initiierte 2016 die Open-Access-Initiative. Open Access bedeutet, Wissen online kostenlos freizugänglich zu machen. Dieser Anspruch setzt eine Digitalisierung voraus, die hochschulübergreifend professionelles Wissen öffentlich macht. Dazu passt die Etablierung einer entsprechenden Online-Datenbank.
Ziel
Mithilfe einer Online-Befragung die Erwartungen potentieller Nutzer an eine Volltextdatenbank zu untersuchen. Mittels eines Fragebogens sollen Nutzerverhalten, Bedürfnisse, Notwendigkeiten erforscht sowie Ideen, Anregungen, persönliche Einschätzungen und mögliche Vor- und Nachteile erfasst werden.
Methode
Durchführung einer Online-Befragung mit 20 Fragen, welche in vier Abschnitte eingeteilt wurden. Geschlossene Fragen wurden deskriptiv ausgewertet, offene Fragen wurden mit der Kernsatzmethode nach Leithäuser und Volmerg (1988) ausgewertet.
Ergebnisse
Insgesamt 84,87 % der 337 Befragten zeigten Interesse an einer Volltextdatenbank für Abschlussarbeiten aus den Therapiewissenschaften. Wünsche der Befragten konnten in den Anforderungskatalog für die zu entwickelnde Volltextdatenbank aufgenommen werden. 67,95 % der Befragten würden sich ein Profil in einer Volltextdatenbank anlegen. Die Vorstellung, eine Abschlussarbeit in einem Videoporträt anzulegen, wurde hingegen von 36,50 % als nicht nützlich bewertet.
Schlussfolgerung
Anhand der Online-Befragung konnten die Rechercheaktivität und die Wünsche an eine Volltextdatenbank abgefragt werden. Die Nutzerakzeptanz kann erst zu einem späteren Zeitpunkt hinreichend bewertet werden, mithilfe einer Evaluationsstudie.
Objective
Brass players are exposed to high musculoskeletal strains during their instrumental play. Various assessments can be used to measure these strains, whereby a targeted therapy can also be supported. The aim of this study was to review literature concerning assessments used in quantitatively based studies about the analysis of musculoskeletal loads of brass players.
Data sources
The Cochrane Library, PubMed, CINAHL, PEDro as well as the journal “Medical Problems of Performing Artists” were searched for relevant studies.
Study selection
Two reviewers independently applied the inclusion and exclusion criteria to select potential studies. A third reviewer was involved in the case of discrepancies.
Data extraction
Two reviewers independently extracted the data.
Data synthesis
A total of 73 studies conducted between 2004 and 2019 were included. Within a total of 30 studies, 18 assessments could be found that collect 2-dimensional or 3-dimensional kinematic data using video- or image-based analysis of posture, sonographic, optoelectronic and various electromagnetic systems. In 7 studies kinetic data were measured by force-transducers, pressure platforms, stabilizer and dynamometer. Fifteen studies used clinical examinations and additional assessments to screen individual body regions and 9 studies derived electromyography measurements from a total of 25 muscles. Thirty-one partially validated questionnaires were used to record musculoskeletal pain of brass players.
Conclusions
A variety of assessments can be used to optimize analysis and treatment procedures in research and clinical work. Future studies should both examine quality criteria of the various assessment methods and validate clinical examinations and questionnaires.
