For the treatment of ULBP, exercise therapy is the treatment of choice. The deadlift exercise is commonly used in athletes to develop basic strength of the trunk muscles but lately it is also suggested to be used in patients with ULBP. Until now, there is no data available how the different gripping techniques affect symmetry during the deadlift and therefore the safety of this exercise in a rehabilitative or preventive setting. The aim of thisstudy wasto investigate whether different gripping techniques during the deadlift exercise affect the symmetry of the ground reaction forces during the exercise. Sixteen healthy participants were asked to perform a deadlift on a ground reaction force plate three times with three different gripping techniques each time. The different gripping techniques were double pronated (DP), handed supinated (HS) and non-handed supinated (NHS). All participants were randomly assigned to three different chronologies of the gripping techniques. The main outcome measurement was the symmetry of the ground reaction forces during the deadlift exercise. Therefore, the maximum side to side differences and the mean side to side differences during the performance of the deadlift were analysed with a repeated measures ANOVA. Post-hoc testing was done with the Bonferroni-test. The three different gripping techniques show significant differences between the groups for the maximal differences (F(1.2)=7.523, p=0.01) and the mean differences (F(1.419)= 6.347, p=0.013). Posthoc testing revealed significant differences between DP and HS for the maximum asymmetry (p=0.009) and for mean asymmetry (p=0.035). Between DP and NHS there were significant differencesfor maxiumum asymmetry (p=0.003) and a tendency for differences for mean asymmetry (p=0.051). No significant differences were found between HS and NHS (p>0.05). The results of this study show that the use of different gripping techniques significantly affect the side to side asymmetry during the deadlift. The DP grip results in lower asymmetry the switch grips HS and NHS. Therefore, this study indicates that the DP gripping style should be used in patients with ULBP.}, language = {en} } @misc{PrillMichelSchulzetal., author = {Prill, Robert and Michel, Sven and Schulz, Robert and Zirr, Matthias and Seeber, Gesine H.}, title = {PO-N-12-SAT2 the influence of an anterior cruciate ligament reconstruction on selected strength parameters five years after injury in competitive Judo athletes}, address = {World Confederation for Physical Therapy (WCPT) Congress Geneva}, language = {en} } @misc{ZirrPrillSchulzetal., author = {Zirr, Matthias and Prill, Robert and Schulz, Robert and Michel, Sven}, title = {PO-J-27-MON1 investigation of the reliability of antrophrometric length measurements with a three-dimensional full-body scanner}, address = {World Confederation for Physical Therapy (WCPT) Congress Geneva}, language = {en} } @misc{PrillSchulzMicheletal., author = {Prill, Robert and Schulz, Robert and Michel, Sven and Becker, Roland}, title = {P20-1308 Lower limb strength and power in competitive Judokas five years after ACLR}, pages = {1}, language = {en} } @misc{PrillSchulzKirschneretal., author = {Prill, Robert and Schulz, Robert and Kirschner, Jana and Michel, Sven and Becker, Roland and Hommel, Hagen}, title = {Reliability, feasibility and performance development of the weight balanced chair rising test in patients before and after total knee arthroplasty}, series = {World Physiotherapy Congress 2021}, journal = {World Physiotherapy Congress 2021}, pages = {1}, abstract = {Knee osteoarthritis is the most prevalent joint disease worldwide and total knee arthroplasty (TKA) is often the only evidence-based treatment option left for patients with endstage osteoarthritis. The postoperative outcomes as well as the different rehabilitation procedures are most commonly evaluated by patient-reported outcome measurements (PROMs). However, in acute clinical-stage stages, performance-based measures were shown to yield greater responsiveness than PROMs, which failed to capture functional declines and may overestimate long-term functional improvements. Moreover, these tests represent a variety of daily life activities which helps to estimate whether a patient is functioning adequately prior to discharge from hospital and in the following rehabilitation. The ability to rise from a sitting position is one of those activities which is important for an elderly person to maintain an independent life. Also, it was shown that chair rising test performance is highly correlated with deviations in gait patterns. However, there is no data available yet if this test can be used at perioperative time-points in patients undergoing TKA and how reliable this test is. Therefore, this study investigates the reliability and the minimal detectable change and the development of the performance of the weight-balanced chair rising test in patients before and after TKA. This study was designed as a test-retest reliability study. Participants were recruited in an orthopedic hospital after they were scheduled for total knee arthroplasty. The participants performed two chair rising tests (five-times-sit-to-stand) on a ground reaction force plate at one-day preoperatively (M0), five days- (M1), ten days (M2)- and ten weeks postoperatively (M3). The test-retest reliability of the weight balanced asymmetry measured as ground reaction force in Newton was analyzed for each of the four time-points. Therefore, the minimal detectable change within a confidence interval of 95\% (MDC95) and the ICC were calculated. 16 male and 8 female subjects (N=24) with a mean age of age 63,93 (±9,59) were included. The mean side-to-side difference in N was 138(±104) at M0, 319(±125) at M1, 254(±109) at M2 and 116(±74) at M3. The test-retest reliability ranged between ICC=.84-.96 at all four time points, indicating good to excellent reliability. The MDC95 ranges from 79-113 N. No adverse events were recorded after the performance of the test and no participants dropped out because of study-related reasons. The weight-balanced chair rising test shows good- to excellent reliability. After an initial decrease of loading symmetry at M1 and M2 preoperative levels are reached as early as at M3. The weight-balanced chair rising test provides objective data about loading symmetry during an activity of daily living. It is reliable and feasible to use in as well in-patient as out- patient rehabilitation of patients with TKA.}, language = {en} } @misc{SchulzPrillKirschneretal., author = {Schulz, Robert and Prill, Robert and Kirschner, Jana and Zirr, Matthias and Michel, Sven}, title = {PO-G-10-SUN2 eccentric training for rotator cuff tendinopathies: a systematic review of randomized controlled trials}, series = {World Confederation for Physical Therapy (WCPT) Congress Geneva}, journal = {World Confederation for Physical Therapy (WCPT) Congress Geneva}, language = {en} } @misc{BrinkmannOberrathAwakowiczetal., author = {Brinkmann, Ralf Peter and Oberrath, Jens and Awakowicz, Peter and Lapke, Martin and Musch, Thomas and Mussenbrock, Thomas and Rolfes, Ilona and Schulz, Christian and Storch, Robert and Styrnoll, Tim and Zietz, Christian}, title = {Device and Use of the Device for Measuring the Density and/or the Electron Temperature and/or the Collision Frequency of a Plasma}, language = {en} }
