Objective A multi-stage, randomised, controlled study design is concerned with the establishment of an evidence-based perioperative physiotherapeutic treatment programme to evaluate physical functional test procedures with regard to their predictive value and the efficacy of physiotherapeutic interventions. Setting The RCT will be realised in a medical clinic in the department of orthopaedics, sports medicine and rehabilitation. Participants A first stage will include young, healthy subjects (Group A) and subjects who are due to undergo TKA and are then to be treated with a standard rehabilitation programme (Group B). Design Selected promising physical functional test procedures will be tested for their reliability. Inter-tester reliability will be determined in Group A. The test-retest reliability at different perioperative timepoints will be determined in Group B. Measurements The following test procedures will be investigated for reliability: 10-m walk test, timed up and go, three times sit to stand, isometric maximal force of knee extension, stair climbing and the cumulative leg circumference. In addition, these test procedures will be correlated among each other and with the WOMAC and KSS for selected aspects of validity. In a second stage, the reliable test procedures will be applied to investigate selected promising physiotherapeutic interventions. Conclusions The investigation could change perioperative assessments and physiotherapeutic treatment in patients who have undergone TKA.

Reliability of the measurement of the spinal height with the VITRONIC 3D-Bodyscanner T2 - Międzynarodowy Dzień Inwalidy, XXIV- Edycja, Życie bez bólu, Zdrowe Dzieci-Zdrowa Europa, Wielka nauka dla małych pacjentów, Zgorzelec, 15-17 marca 2018 N2 - Low back pain is one of the most common diseases in industrial society with a major impact on quality of life. It is suggested that approximately 40% of chronic low back pain (CLBP) is disc related in form of internal disc disruptions. Dehydration of the disc leads to stress concentrations in the disc itself and apophyseal joints. Upright-MRI is likely to become the ‘gold-standard’-measurement for determination of IVD heights, its practical usability will remain limited because of its high cost and its low availability. The aim of this study is to investigate the accuracy and reliability of the measurement of the height of the spine with the 3D-Bodyscanner. Therefore, the reliability of different measurement settings (S) had to be investigated. S1: At first it was investigated, if the length of the spine can be measured reliable with the 3D-Bodyscanner when the same person is measured twice without moving between the measurements. The reliability and the first tester influenced bias is estimated. S2: The same person was measured after the person moved from the chair in between both measurements. S3: The participants were measured twice and the markers were renewed between both measurements. Furthermore, the standard error of measurement (SEm) was estimated to compare the accuracy of this measurement with expectable changes in spinal height in daily live and different research tasks . 14 healthy men and 14 healthy women participated in this study. The following pearson correlation coefficients (r) and SEms resulted from the different measurement settings: S1: The measurement of the spinal length in humans that did not move in between the two measurements correlated with r=0.99. This resulted in a SEm of 3.5mm. S2: The measurement of the spinal length in humans that moved in between the measurements but kept the same markers on their spine correlated with r=0.98. This resulted in a SEm of 4.1mm. S3: The measurement of the spinal length in humans that moved in between the measurements and got new markers applied on their spine correlated with r=0.95. This resulted in a SEm of 7.1mm. The measurement of the spinal height with the VITRONIC 3D-Bodyscanner appears to be highly reliable, especially if the markers do not have to be renewed for the retest (S1 and S2). The accuracy of this measurement method seems to be high enough to measure the exercise- or traction induced height changes in the spine. In the case of measuring the height change that is induced by 10 minutes of different types of positioning, the change is maybe to small to be detected. Even if the markers have to be renewed, the accuracy is still discussable to measure diurnal height changes. In conclusion, the 3D-Bodayscanner appears to be a more cost-effective alternative for the measurement of specific segments of the spine than MRI and a practicable alternative for science in the field of de- and rehydration.

A randomized, controlled and double-blind pilot cross-over trial T2 - The Journal of Sports Medicine and Physical Fitness N2 - OBJECTIVES: The symptomatic reduction of exercise-induced delayed onset muscle soreness (DOMS) is of great interest in the fields of Sports Medicine and Physical Therapy. At this time, few therapeutic interventions have proven their effectiveness. One of the most promising interventions is Compression Therapy. The object of this study is Tissue Flossing, a therapeutic short-term compression method and whether its post-exercise application can reduce the extent of perceived DOMS. DESIGN: randomized, controlled, and double-blind pilot cross-over trial. METHODS: Participants (n = 17) without any musculoskeletal injuries were recruited from university students. Participants performed an exercise protocol and obtained the intervention subsequently on one of both arms. Participants had to return for a second day to perform the whole procedure again, this time receiving the flossing intervention on the other arm. At both time points their opposite arms served as the control. The primary outcome measure was a patient reported visual analogue scale 100mm. RESULTS: The mean value of DOMS of the flossed arm was 42mm compared to the non-flossed arm with 48mm. Differences were found to be statistically significant at 24 hours- (p=0,036; α=0.05), as well as at 48 hours post-intervention (p=0,035; α=0.05). Effect sizes were dz=0,408 at 24 hours-and dz=0,411 at 48 hours post-intervention. The clean language effect size was 0.66. CONCLUSIONS: Tissue flossing appears to be an effective method for treating DOMS which is slightly less effective but much more practicable than gold standard treatment.

Athletes rarely return to the peak of performance or are limited in their ability to perform their sport. Performance tests for ACLR are still immature and often unspecific. In Judo, the ability to stand on one's feet is an essential prerequisite for many situations. An unstable standing position also promotes knee injuries. In order to check the stability of the single leg stand, a controlled test-re-test design is used in the present study. Two groups are included: A (n=27): Judoka without anamnestically relevant injuries of the lower extremities or the back and B (n=17): Judoka 5.06 ± 1.06 years after ACLR. A one-legged hop test up on a piezoelectric force plate is examined for reliability with respect to the test repetition and validity with regard to the predicted identification of deficits in a side-by-side comparison. In this test, the test person jumps with one leg on the force plate at a defined distance and tries to stand as still as possible, which means that hardly any horizontal force is generated. Both tests are carried out one after the other with both legs and with sufficient break twice each. In group A, there were no significant differences (p>0.05) between the subjectively better leg and the subjectively worse leg, or the leg in the front and rear of the kumi-kata in Judo. In group B, in the first experiment with the ACLR leg, the test persons generate a significantly higher horizontal force in a 95% confidence interval of the bilateral coefficient of CI=[0.16-0.76] compared to the side not affected (p=0.017). In the test repetition, Group B generates with the affected leg significantly less horizontal force surges than in the first attempt. No significant differences in lateral comparison could be measured, although there is a reliability coefficient of r=0.89 for the ACLR leg, but only r=0.35 for the unaffected leg and r=0.53 for group A. It is concluded that the test for asymptomatic judokas cannot be regarded as sufficiently selective due to the low requirement. In group B, in the second experiment, a feed-forward model including pre-activation based on empirical values from the first experiment could explain the improvement, which has led to no significant differences between legs.
