Performance-based measures are necessary to capture different aspects of physical function. High reliability and agreement of five performance-based measures were hypothesized to differentiate between measurement error and change in test performance. Secondary outcomes are the correlation of performance-based measurements to KSS and WOMAC prior to surgery (baseline) and 10 weeks thereafter (t3). Methods The test-retest reliabilities and agreements of the 1-m walk test, the stair-climbing test, the timed-up-and-go test, the weight-balanced-chair-rising test and the isometric maximum knee extension force in patients undergoing total knee replacements were studied. The intraclass correlation coefficient was calculated and a Bland-Altman analysis performed. The weight-balanced-chair-rising test showed a symmetry at baseline = 0.77, 5 ± 1 days after surgery (t1) = 0.50, 9 ± 1 days (t2)= 0.59 and (t3)= 0.80. All performance tests showed high intraclass correlation coefficients (ICC= 0.81-0.99). The 10-m walk test, stair climbing test, and the timed-up-and-go test showed high agreement in the Bland-Altman analysis. The Bland-Altman analysis for the weight-balanced-chair-rising test and isometric knee extension force indicated high agreement at 5 and 9 days postoperatively, but the relative measurement error increased pre- and 10 weeks postoperatively. In conclusion, symmetry, as an important outcome after TKA, is a reliable and rather unique item that should unquestionably be added to established measurements like walking tests or survey-based function assessment. The implementation of standardized performance-based measures to assess physical function in rehabilitation procedures will help to improve the more objectively based assessment of different rehabilitation protocols.}, language = {en} } @misc{PrillBeckerMichel, author = {Prill, Robert and Becker, Roland and Michel, Sven}, title = {Kraftindex deutet bei Judoka 5 Jahre nach Kreuzbandruptur auf Muskelfaserspektrums{\"a}nderung hin}, series = {Sports Orthopaedics and Traumatology}, volume = {38}, journal = {Sports Orthopaedics and Traumatology}, number = {2}, issn = {1876-4339}, doi = {10.1016/j.orthtr.2022.02.025}, pages = {198 -- 199}, language = {de} } @misc{EckeScholkaHanschetal., author = {Ecke, Annemarie and Scholka, Jenny and Hansch, Anna and Becker, Roland and Anderer, Ursula}, title = {Differentiation of human articular chondrocytes in microtissues depends on the cell aggregation technique}, pages = {1}, language = {en} } @misc{PrillKrolikowskaSchulzetal., author = {Prill, Robert and Krolikowska, Aleksandra and Schulz, Robert and Oleksy, Lukasz and Michel, Sven and Becker, Roland}, title = {Verletzungen im Judo - Risikosportart oder Risikosportler?}, series = {Sports Orthopaedics and Traumatology}, volume = {2}, journal = {Sports Orthopaedics and Traumatology}, number = {39}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0949-328X}, doi = {10.1016/j.orthtr.2023.03.008}, pages = {185}, language = {de} } @misc{KirschnerMichelBeckeretal., author = {Kirschner, Jana and Michel, Sven and Becker, Roland and Stiebitz, Olaf and Hommel, Hagen and Schulz, Robert and Daszkiewicz, Maciej and Krolikowska, Aleksandra and Prill, Robert}, title = {Determination of Relationships between Symmetry-Based, Performance-Based, and Functional Outcome Measures in Patients Undergoing Total Hip Arthroplasty}, series = {Journal of Personalized Medicine}, volume = {13}, journal = {Journal of Personalized Medicine}, number = {7}, issn = {2075-4426}, doi = {10.3390/jpm13071046}, abstract = {Due to the high heterogeneity in outcome measures after total hip arthroplasty (THA), the prospective observational study investigated the relationships between symmetry-based (SBMs), performance-based (PBMs), and functional outcome measures in THA patients to determine necessary or redundant categories of tests. The study material consisted of 24 patients with end-stage hip osteoarthritis scheduled for THA. The patients were examined one day before surgery and consecutively on the 4th day, 9th day, and 10th week postoperatively using the SBMs (weight-bearing chair-rising test, measurements of the maximal isometric torque of the quadriceps muscle); the PBMs (10-m walk, timed up-and-go, and stair-climbing tests); and the functional outcome measure (Harris Hip Score). The results obtained in a given category of tests at different time points were compared, and the correlations between the tests were determined. The reliability of the outcome measures was determined. The results of tests in the studied categories statistically significantly (p < 0.05) improved at the 10th week postoperatively compared to preoperative results. No strong correlations were revealed between the three studied types of outcome measures in THA patients. Therefore, none of them can be considered redundant. It also means that the relevance of symmetry for a core measurement set to describe the domain function in THA patients must be further clarified.}, language = {en} } @misc{JahnkeCruysenPrilletal., author = {Jahnke, Sonja and Cruysen, Caren and Prill, Robert and Kittmann, Fabian and Pflug, Nicola and Albert, Justin Amadeus and Camargo, Tibor de and Arnrich, Bert and Krolikowska, Aleksandra and Kolcz, Anna and Reichert, Pawel and Oleksy, Lukasz and Michel, Sven and Kopf, Sebastian and Wagner, Michael and Scheffler, Sven and Becker, Roland}, title = {Protocol for a Randomized Crossover Trial to Evaluate the Effect of Soft Brace and Rigid Orthosis on Performance and Readiness to Return to Sport Six Months Post‑ACL‑Reconstruction}, series = {Healthcare}, volume = {11}, journal = {Healthcare}, number = {4}, issn = {2227-9032}, doi = {10.3390/healthcare11040513}, abstract = {A randomized crossover trial was designed to investigate the influence of muscle activation and strength on functional stability/control of the knee joint, to determine whether bilateral imbalances still occur six months after successful anterior cruciate ligament reconstruction (ACLR), and to analyze whether the use of orthotic devices changes the activity onset of these muscles. Furthermore, conclusions on the feedforward and feedback mechanisms are highlighted. Therefore, twenty‑eight patients will take part in a modified Back in Action (BIA) test battery at an average of six months after a primary unilateral ACLR, which used an autologous ipsilateral semitendinosus tendon graft. This includes double‑leg and single‑leg stability tests, double‑leg and single‑leg countermovement jumps, double‑leg and single‑leg drop jumps, a speedy jump test, and a quick feet test. During the tests, gluteus medius and semitendinosus muscle activity are analyzed using surface electromyography (sEMG). Motion analysis is conducted using Microsoft Azure DK and 3D force plates. The tests are performed while wearing knee rigid orthosis, soft brace, and with no aid, in random order. Additionally, the range of hip and knee motion and hip abductor muscle strength under isometric conditions are measured.
