The aetiology and chronification of back pain can be best described as an interaction between biological, psychological, and social processes. However, to date, multimodal prevention and intervention programs for back pain that target all three aetiological factors have demonstrated limited effectiveness. This lack of supportive evidence for multimodal programmes in the treatment of back pain could be due to the fact that few programs are suitable for long-term and unsupervised use in everyday life. Moreover, in combining the elements from various therapies, little attention has been paid to the mechanisms underlying the synergistic effects of the separate components. In this contribution, we will describe the development of a new multimodal intervention for back pain that set out to address these limitations. To this end, the biological elements of neuromuscular adaptation is supplemented with cognitive behavioral and psychophysiological techniques in an intervention that can be followed at home as well as in clinics, and that is suitable for all grades of pain. The efficacy of this intervention will be tested in a multicentric randomized controlled longitudinal trial (n = 714) at five time points over a period of 6 months. Here we will describe the development and the content of this new intervention.}, language = {de} } @article{WippertArampatzisBanzeretal.2019, author = {Wippert, Pia-Maria and Arampatzis, Adamantios and Banzer, Winfried and Beck, Heidrun and Hasenbring, Monika Ilona and Schiltenwolf, Marcus and Schneider, Christian and Stengel, Dirk and Platen, Petra and Mayer, Frank}, title = {Psychosoziale Risikofaktoren in der Entstehung von chronisch unspezifischen R{\"u}ckenschmerzen}, series = {Zeitschrift f{\"u}r Sportpsychologie}, volume = {26}, journal = {Zeitschrift f{\"u}r Sportpsychologie}, number = {1}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {1612-5010}, doi = {10.1026/1612-5010/a000245}, pages = {25 -- 35}, year = {2019}, abstract = {Chronisch unspezifische R{\"u}ckenschmerzen (CURS) geh{\"o}ren international zu den h{\"a}ufigsten Schmerzph{\"a}nomenen und k{\"o}nnen f{\"u}r Athletinnen und Athleten karrierelimitierend sein.

As elevations of the cardiac biomarkers troponin and BM) have been observed frequently for the vast majority of athletes after Marathon runs or strenuous exercise bouts followed by a decrease within a short period, a physiological reaction rather than a pathologicial cause is presumed. Also a transient decrease of cardiac function demonstrated by newer echocardiographic techniques (tissue Doppler or speckle tracking imaging, 3D echocardiography) after strenuous exercise often termed "cardiac fatigue" should not be considered necessarily as pathologic, as cardiac function also depends on hemodynamic load and heart rate. Furthermore, exercise-induced changes in cardiac function did not correlate with exercise-induced increases in cardiac biomarkers in most studies. The functional cardiac alterations can also be detected by magnetic resonance imaging (MRI) after Marathon runs. However, no signs of acute or chronic myocardial damage have been demonstrated in MRI studies in cardiovascular healthy athletes after running a Marathon, although especially in older athletes undetected cardiovascular diseases such as coronary artery disease or myocardial necrosis or fibrosis can be present. hi conclusion, according to recent studies. there seems to be a lack of evidence to support endurance exercise-induced cardiac damage in the healthy heart which is adapted tostrenous exercise by regular endurance training. Nevertheless, as running a Marathon results in a high cardiac load, a sufficient endurance training period as well as a preparticipation or regular medical screening to exclude relevant congenital or aquired cardiovascular diseases is recommended from a sports cardiology perspective to exclude relevant congenital or acquired cardiovascular diseases}, language = {de} } @article{MuellerBaurHirschmuelleretal.2006, author = {M{\"u}ller, Steffen and Baur, Heiner and Hirschmueller, Anja and Mayer, Frank}, title = {Validit{\"a}t des COP-Verlaufes zur Quantifizierung der funktionalen Gangentwicklung bei Kindern}, year = {2006}, abstract = {Functional gait development in children is discussed controversially. Differentiated information about the roll- over process of the foot, represented by the "Center of Pressure" (COP), are still missing. The purpose of the study was the validation of the COP-path to quantify the functional gait development of children. Plantar pressure distribution was measured barefoot with an individual speed on a walkway (tartan) - in 255 children aged between 2 and 15 years. The medial and lateral area enclosed between the COP-path and the bisection of plantar angle (A(med), A(lat), Sigma: A(ml)) was calculated from plantar pressure data. Furthermore, the duration of the COP-path in the heel (COPtimeF), midfoot (COPtimeM) and forefoot (COPtimeV) was analysed. The load distribution under the medial and lateral forefoot was also calculated. The variation coefficient (VC) was calculated as a measure of interindividual variability. The medio-lateral divergency of the COP (Aml) initially decreases with advancing age (-20.2\%), followed by a continuous increase (+27.2\%). No changes in VC (A(med), A(lat), and A(ml)) appeared during age-related development. COPtimeM remains constant in all children over time. In contrast to COPtimeM, Cop(time)F decreases from youngest to oldest children (-31.0\%), and COPtimeV increases (+41.7\%). After initial descent up to 8 years of age, VC (COPtimeF, COPtimeM, COPtimeV) remains constant. The mediolateral load under the forefoot did not change. The COP-Path is able to characterise the functional gait development of children. VC values indicate high individual variability of gait pattern.

Materials and Methods: 1906 Achilles tendons of 953 long distance runners were examined by ultrasound and power Doppler (Toshiba Aplio SSA-770A/80 12 MHz). Ultrasound images (spindle-shaped thickening, hypoechoic/hyperechoic lesions, neovascularizations) were analyzed in relation to the runners' anthropometrical data and history of Achilles tendon complaints. Results: In asymptomatic runners as well as in the overall group, there was a statistically significant correlation between tendon thickness and age, height and weight (CC 0.24 - 0.38, p < 0.001). Runners with current or healed Achilles tendon complaints displayed a statistically significant thickening of the tendons, as well as an increase in hypoechoic lesions and neovascularizations (p < 0.001). While grayscale abnormalities were rarely found in asymptomatic runners (< 10\%), neovascularization was detected in 35\% of healthy test persons using the high-resolution power Doppler "Advanced Dynamic Flow". Conclusion: Contrary to frequent assumption, neovascularization is often found in tendons of asymptomatic runners, using modern power Doppler equipment.

The present study therefore aims to evaluate the reliability of measurements of Achilles- and Patella tendon diameter and in the detection of structural adaptations. Materials and Methods: In 14 healthy, recreationally active subjects both asymptomatic Achilles (AT) and patella tendons (PT) were measured twice by two examiners in a test-retest design. Besides the detection of anteroposterior (a.p.-) and mediolateral (m.l.-) diameters, areas of hypoechogenicity and neovascularisation were registered. Data were analysed descriptively with calculation of test-retest variability (TRV), intraclass-correlation coefficient (ICC) and Bland and Altman's plots with bias and 95\% limits of agreement (LOA). Results: Intra- and interrater differences of AT- and PT-a.p.-diameter varied from 0.2 - 1.2 mm, those of AT- and PT-m.l-diameter from 0.7-5.1 mm. Areas of hypoechogenicity were visible in 24\% of the tendons, while 15\% showed neovascularisations. Intrarater AT-a.p.-diameters showed sparse deviations (TRV 4.5-7.4\%; ICC 0.60-0.84; bias -0.05-0.07 mm; LOA-0.6-0.5 to -1.1 - 1.0 mm), while interrater AT- and PT-m.l.-diameters were highly variable (TRV 13.7-19.7\%; ICC 0.11-0.20; bias -1.4-4.3 mm; LOA-5.5-2.7 to -10.5 - 1.9 mm). Conclusion: Our results suggest that the measurement of AT- and PT-a.p.-diameters is a reliable parameter. In contrast, reproducibility of AT- and PT-m.l.-diameters is questionable.

Data analyzing clinical or biomechanical effects of those interventions is sparse. Foot orthoses out of carbon fiber are one possibility to alter the interface between foot and pedal. The aim of this study was therefore to analyze plantar pressure distribution in carbon fiber foot orthoses in comparison to standard insoles of commercially available cycling shoes. Materials and Methods: 11 pain-free triathletes (Age: 29 +/- 9, 1.77 +/- 0.04 m, 68 5 kg) were tested on a cycle ergometer at 60 and 90 rotations per minute (rpm) at workloads of 200 and 300 Watts. Subjects wore in randomized order a cycling shoe with its standard insole (control condition CO) or the shoe with carbon fiber foot orthoses (Condition CA). Mean peak pressure out of 30 movement cycles were extracted for the total foot and specific foot regions (rear, mid, fore foot (medial, central, lateral) and toe region). Three-factor ANOVAs (factor foot orthoses, rpm, workload) for repeated measures (alpha = 0.05) were used to analyze the main question of a foot orthoses effect on peak in-shoe plantar pressure. Results: Peak pressures in the total foot were in a range of 70-75 kPa for 200 Watts (W) (300 W: 85-110 kPa). The carbon fiber foot orthoses reduced peak pressures by -4,1\% compared to the standard insole (p = 0,10). In the foot regions rear(-16,6\%, p<0.001), mid (-20,0\%, p<0.001) and fore foot (-5.9\%, p < 0.03)CA reduced peak pressure compared to CO. In the toe region, peak pressure was higher in CA (+16,2\%) compared to CO (p<0,001). The lateral fore foot showed higher peak pressures in CA (+34\%) and CO (+59\%) compared to medial and central fore foot. Conclusion: Carbon fiber can serve as a suitable material for foot orthoses manufacturing in cycling. Plantar pressures do not increase due to the stiffness of the carbon.
