    <title language="eng">Biomechanical characteristics of knee rehabilitation exercises: a new approach for data-based exercise selection</title>
    <abstract language="eng">Purpose:&#13;
The principal objective of our research is to characterize key exercises that represent significant milestones in the rehabilitation process, employing biomechanical parameters to facilitate the distinction between stages of progression.&#13;
Methods:&#13;
&#13;
We conducted an observational cross-sectional study on healthy volunteers (30 years), approved by an ethics committee. Subjects with a history of lower extremity disease were excluded. Movement data was collected, including the following hierarchy of exercise progressions: sit-to-stand-supported (STSS) - sit-to-stand (STS) - squat, stair climbing supported (SCS) - stair climbing (SC) - step-up, single-leg-stance-supported (SLSS) - single-leg-stance (SLS) - single-leg-stance-advanced (SLSA). Motion data was captured using a marker-less system (CapturyLive, v255, TheCaptury, Germany) and used for musculoskeletal simulations in the AnyBody Modeling System (v7.4.4, AnyBodyTechnology, Denmark) with a full-body model. ANOVA or Welch-Test with Bonferroni Post-Hoc was used to describe the anterior-posterior joint reaction force (JRF) normalized for body weight (BW) for each exercise. Positive values indicate an anterior JRF, and negative values a posterior JRF.&#13;
Results:&#13;
We recruited 31 subjects (female: 23/74.2%) with a mean age of 22.81 years (SD:2.18). The analysis showed a significant difference in minimum JRF for STSS, STS, and squat (Welch-Test: F(2,56.421)=71.216, p0.001). Post-hoc analysis revealed that posterior JRF for STSS (mean:-2.63BW, SD:0.53) was lower than for STS (mean:-3.74BW, SD:0.42, p0.001), and STS was lower than squat (mean:-4.02BW, SD:0.35, p=0.043). No significant differences were observed in maximum JRF in the posterior direction (ANOVA: F(2,87)=1.151, p=0.324). For single-leg-stance exercises, the minimum JRF was similar for SLSS (mean:-0.34BW, SD:0.22) and SLS (mean:-0.55BW, SD:0.25, p=0.056), but higher in the posterior direction for SLSA (mean:-0.98BW, SD:0.49, p0.001; Welch-Test: F(2,54.379)=22.536, p0.001). Maximum JRF differences were also significant (ANOVA: F(2,87)=11.546, p0.001), with SLSS (mean:0.01BW, SD:0.22) showing a significant higher anterior JRF compared to SLS (mean:-0.16BW, SD:0.19, p=0.020). In the progression from SCS, SC to step-up, there was a significant difference in minimum JRF (ANOVA: F(2,87)=5.33, p=0.007), but not in maximum JRF (ANOVA: F(2,87)=0.624, p=0.538). SCS (mean:-3.42BW, SD:0.38) and SC (mean:-3.48BW, SD:0.54) showed no difference (p=1.000), but SC was significantly higher than step-up (mean:-3.58BW, SD:0.62, p=0.036).&#13;
&#13;
&#13;
Conclusion(s):&#13;
&#13;
The exercises show differences in the JRF according to stages of progression, which can be taken into account when selecting exercises. Future research should address the group of patients who have undergone knee arthroplasty.&#13;
Implications:&#13;
In the future, it may be feasible to quantify patients' resilience based on sensor data and associate this with the optimal progression of an exercise sequence throughout the rehabilitation process.</abstract>

    <title language="eng">Impact of Model Parameters on Ground Reaction Force Predictions in Musculoskeletal Modelling</title>
    <abstract language="eng">This study evaluated how model parameters affect ground reaction force (GRF) predictions in musculoskeletal simulations. A parameter study varying contact height and velocity thresholds and marker weights was conducted. While height and velocity thresholds had minimal impact, marker weights impact prediction errors. These findings highlight the importance of carefully selecting model parameters.</abstract>

    <title language="eng">Comparing kinematic and kinetic demands on the knee joint during selected physiotherapy exercises and activities of daily living</title>
    <abstract language="eng">Background: The knee is one of the most common areas to suffer injuries or be affected by surgery. Physiotherapy rehabilitation was shown to support recovery, but evidence guiding optimal rehabilitation practices is limited. To recommend appropriate exercises, it is essential to understand the musculoskeletal requirements involved in both physiotherapy and activities of daily living (ADLs).ObjectiveThis study aimed to evaluate and compare the knee joint kinematics, joint forces and muscle activity in knee flexors and extensors during selected rehabilitation exercises and ADLs.MethodsKinematic and kinetic data from 30 healthy participants were collected during 20 different tasks. Full-body musculoskeletal simulations were performed to estimate peak knee joint angles, angular velocities, joint reaction forces, and muscle activity of the knee flexors and extensors.ResultsComparatively high requirements were observed for lunges, squats, stair walking and gait. Medium requirements were observed for sitting down and rising from a chair. Low requirements were observed for balance shifts and variations of the single leg stand.ConclusionOverall, ADLs like gait and stair walking show surprisingly high requirements compared to many exercises employed in physiotherapy. These findings are a step towards biomechanically informed exercise selection and the development of personalized rehabilitation programs.</abstract>
