Stress and Alterations in the Pain Matrix
The genesis of chronic pain is explained by a biopsychosocial model. It hypothesizes an interdependency between environmental and genetic factors provoking aberrant long-term changes in biological and psychological regulatory systems. Physiological effects of psychological and physical stressors may play a crucial role in these maladaptive processes. Specifically, long-term demands on the stress response system may moderate central pain processing and influence descending serotonergic and noradrenergic signals from the brainstem, regulating nociceptive processing at the spinal level. However, the underlying mechanisms of this pathophysiological interplay still remain unclear. This paper aims to shed light on possible pathways between physical (exercise) and psychological stress and the potential neurobiological consequences in the genesis and treatment of chronic pain, highlighting evolving concepts and promising research directions in the treatment of chronic pain. Two treatment forms (exercise and mindfulness-based stress reduction as exemplary therapies), their interaction, and the dose-response will be discussed in more detail, which might pave the way to a better understanding of alterations in the pain matrix and help to develop future prevention and therapeutic concepts

Trunk Muscle Activity during Drop Jump Performance in Adolescent Athletes with Back Pain
In the context of back pain, great emphasis has been placed on the importance of trunk stability, especially in situations requiring compensation of repetitive, intense loading induced during high-performance activities, e.g., jumping or landing. This study aims to evaluate trunk muscle activity during drop jump in adolescent athletes with back pain (BP) compared to athletes without back pain (NBP). Eleven adolescent athletes suffering back pain (BP: m/f: n = 4/7; 15.9 ± 1.3 y; 176 ± 11 cm; 68 ± 11 kg; 12.4 ± 10.5 h/we training) and 11 matched athletes without back pain (NBP: m/f: n = 4/7; 15.5 ± 1.3 y; 174 ± 7 cm; 67 ± 8 kg; 14.9 ± 9.5 h/we training) were evaluated. Subjects conducted 3 drop jumps onto a force plate (ground reaction force). Bilateral 12-lead SEMG (surface Electromyography) was applied to assess trunk muscle activity. Ground contact time [ms], maximum vertical jump force [N], jump time [ms] and the jump performance index [m/s] were calculated for drop jumps. SEMG amplitudes (RMS: root mean square [%]) for all 12 single muscles were normalized to MIVC (maximum isometric voluntary contraction) and analyzed in 4 time windows (100 ms pre- and 200 ms post-initial ground contact, 100 ms pre- and 200 ms post-landing) as outcome variables. In addition, muscles were grouped and analyzed in ventral and dorsal muscles, as well as straight and transverse trunk muscles. Drop jump ground reaction force variables did not differ between NBP and BP (p > 0.05). Mm obliquus externus and internus abdominis presented higher SEMG amplitudes (1.3–1.9-fold) for BP (p < 0.05). Mm rectus abdominis, erector spinae thoracic/lumbar and latissimus dorsi did not differ (p > 0.05). The muscle group analysis over the whole jumping cycle showed statistically significantly higher SEMG amplitudes for BP in the ventral (p = 0.031) and transverse muscles (p = 0.020) compared to NBP. Higher activity of transverse, but not straight, trunk muscles might indicate a specific compensation strategy to support trunk stability in athletes with back pain during drop jumps. Therefore, exercises favoring the transverse trunk muscles could be recommended for back pain treatment.

Star Excursion Balance Test in young athletes with back pain
The Star Excursion Balance Test (SEBT) is effective in measuring dynamic postural control (DPC). This research aimed to determine whether DPC measured by the SEBT in young athletes (YA) with back pain (BP) is different from those without BP (NBP). 53 BP YA and 53 NBP YA matched for age, height, weight, training years, training sessions/week and training minutes/session were studied. Participants performed 4 practice trials after which 3 measurements in the anterior, posteromedial and posterolateral SEBT reach directions were recorded. Normalized reach distance was analyzed using the mean of all 3 measurements. There was no statistical significant difference (p > 0.05) between the reach distance of BP (87.2 ± 5.3, 82.4 ± 8.2, 78.7 ± 8.1) and NBP (87.8 ± 5.6, 82.4 ± 8.0, 80.0 ± 8.8) in the anterior, posteromedial and posterolateral directions respectively. DPC in YA with BP, as assessed by the SEBT, was not different from NBP YA.

Postural control and back pain in adolescent athletes
Posturale Kontrolle und Rückenschmerzen bei Nachwuchsathleten
Back pain is a problem in adolescent athletes affecting postural control which is an important requirement for physical and daily activities whether under static or dynamic conditions. One leg stance and star excursion balance postural control tests are effective in measuring static and dynamic postural control respectively. These tests have been used in individuals with back pain, athletes and non-athletes without first establishing their reliabilities. In addition to this, there is no published literature investigating dynamic posture in adolescent athletes with back pain using the star excursion balance test. Therefore, the aim of the thesis was to assess deficit in postural control in adolescent athletes with and without back pain using static (one leg stance test) and dynamic postural (SEBT) control tests.
Adolescent athletes with and without back pain participated in the study. Static and dynamic postural control tests were performed using one leg stance and SEBT respectively. The reproducibility of both tests was established. Afterwards, it was determined whether there was an association between static and dynamic posture using the measure of displacement of the centre pressure and reach distance respectively. Finally, it was investigated whether there was a difference in postural control in adolescent athletes with and without back pain using the one leg stance test and the SEBT.
Fair to excellent reliabilities was recorded for the static (one leg stance) and dynamic (star excursion balance) postural control tests in the subjects of interest. No association was found between variables of the static and dynamic tests for the adolescent athletes with and without back pain. Also, no statistically significant difference was obtained between adolescent athletics with and without back pain using the static and dynamic postural control test.
One leg stance test and SEBT can be used as measures of postural control in adolescent athletes with and without back pain. Although static and dynamic postural control might be related, adolescent athletes with and without back pain might be using different mechanisms in controlling their static and dynamic posture. Consequently, static and dynamic postural control in adolescent athletes with back pain was not different from those without back pain. These outcome measures might not be challenging enough to detect deficit in postural control in our study group of interest.
Rückenschmerzen sind ein zunehmendes Problem bei Nachwuchsathleten und beeinflussen die statische und dynamische posturale Kontrolle, die eine wichtige Voraussetzung für sportliche als auch tägliche Aktivitäten darstellt. Der Stand auf einem Bein und der Star Excursion Balance Test (SEBT) sind effektive Tests zur Beurteilung der statischen bzw. dynamischen posturalen Kontrolle. Beide Tests wurden bereits bei Populationen mit Rückenschmerzen, Sportlern und Nicht-Sportlern angewandt, ohne vorherige Reliabilitätsmessung. Des Weiteren wurde bisher die dynamische posturale Kontrolle mittels des SEBT bei Nachwuchsathleten mit Rückenschmerzen nicht untersucht. Daher ist das Ziel dieser Arbeit die posturale Kontrolle von Nachwuchsathleten mit Rückenschmerzen mit Hilfe eines statischen (Einbeinstand) und eines dynamischen (SEBT) Tests zu beurteilen.
Nachwuchsathleten mit und ohne Rückenschmerzen wurden mit Hilfe der beiden Tests untersucht. Die Reproduzierbarkeit beider Untersuchungen wurde durch vorhergehende Messungen sichergestellt. Anschließend wurde untersucht, ob es einen Zusammenhang zwischen der statischen und dynamischen posturalen Kontrolle gibt, indem die Abweichungen des Druckmittelpunktes (center of pressure) auf einer Kraftmessplatte mit der erreichten Reichweite beim SEBT verglichen wurden. Abschließend konnte untersucht werden ob es einen Unterschied in der posturalen Kontrolle zwischen Nachwuchsathleten mit und ohne Rückenschmerzen gibt.
Es konnten moderate bis hervorragende Reliabilitätswerte für den statischen (Einbeinstand) und dynamischen (SEBT) Test der posturalen Kontrolle in der untersuchten Zielgruppe festgestellt werden. Es konnte kein Zusammenhang zwischen den Parametern des statischen und des dynamischen Tests bei Nachwuchsathleten mit und ohne Rückenschmerzen gefunden werden. Weiterhin gab es keinen signifikanten Unterschied zwischen den Parametern der statischen und dynamischen Haltungskontrolle in der beschriebenen Population.
Der Einbeinstand auf der Kraftmessplatte und der SEBT können zur Beurteilung der Haltungskontrolle bei Nachwuchsathleten mit und ohne Rückenschmerzen eingesetzt werden. Der fehlende Zusammenhang zwischen den Parametern der statischen und dynamischen Haltungskontrolle könnte darauf zurückzuführen sein, dass verschiedene neuromuskuläre Mechanismen für die Regulierung der statischen und dynamischen Haltungskontrolle bei den Athleten verantwortlich sein könnten. Demzufolge gab es keinen Unterschied, weder in der statischen noch in der dynamischen posturalen Kontrolle, zwischen Nachwuchsathleten mit und ohne Rückenschmerzen. Anspruchsvollere Aufgaben sind nötig um die Defizite in der Haltungskontrolle von Nachwuchsathleten zu untersuchen.
