“…The technique has been used in a variety of activities and partic ularly found its applications for high pace movements of sports biomechanics (Table 2). A common use has been to find a set of muscle activations that can reliably repro duce the movement pattern, and subsequently perturb parameters of the optimal solution to explore injury mech anisms (McLean et al, 2004;McLean et al, 2003). This strategy is advantageous due to the more straightforward inclusion of muscle dynamics within the solution when compared to inverse dynamics-based static optimization (Happee, 1994).…”

“…A few Monte Carlo models have been developed to model biomechanical and musculoskeletal phenomena, 14,20,32,55,56,59,75 but such work has been limited. Monte Carlo methods utilize input parameter distributions to model intersubject variability, and therefore provide distributions of output values.…”

A Probabilistic Model of Glenohumeral External Rotation Strength for Healthy Normals and Rotator Cuff Tear Cases

The reigning paradigm of musculoskeletal modeling is to construct deterministic models from parameters of an "average" subject and make predictions for muscle forces and joint torques with this model. This approach is limited because it does not perform well for outliers, and it does not model the effects of population parameter variability. The purpose of this study was to simulate variability in musculoskeletal parameters on glenohumeral external rotation strength in healthy normals, and in rotator cuff tear cases using a Monte Carlo model. The goal was to determine if variability in musculoskeletal parameters could quantifiably explain variability in glenohumeral external rotation strength. Multivariate Gamma distributions for musculoskeletal architecture and moment arm were constructed from empirical data. Gamma distributions of measured joint strength were constructed. Parameters were sampled from the distributions and input to the model to predict muscle forces and joint torques. The model predicted measured joint torques for healthy normals, subjects with supraspinatus tears, and subjects with infraspinatus-supraspinatus tears with small error. Muscle forces for the three conditions were predicted and compared. Variability in measured torques can be explained by differences in parameter variability.

“…[27][28][29] These mechanisms usually involve tibial rotation. 26,27,[30][31][32][33][34] Feagin and Lambert reported a sudden deceleration, fixed foot, and a change in direction as mechanisms underlying ACL injuries. 29 A number of studies based on cadaver models showed that internal tibial rotation loads the ACL strongly, [35][36][37][38] which may result in injury to the ligament.…”

The anterior cruciate ligament (ACL) is the most commonly injured knee ligament with the highest incidence of injury in female athletes who participate in pivoting sports. Noncontact ACL injuries commonly occur with both internal and external tibial rotation. ACL impingement against the lateral wall of the intercondylar notch during tibial external rotation and abduction has been proposed as an injury mechanism, but few studies have evaluated in vivo gender-specific differences in laxity and stiffness in external and internal tibial rotations. The purpose of this study was to evaluate these differences. The knees of 10 male and 10 female healthy subjects were rotated between internal and external tibial rotation with the knee at 608 of flexion. Joint laxity, stiffness, and energy loss were compared between male and female subjects. Women had higher laxity (p ¼ 0.01), lower stiffness (p ¼ 0.038), and higher energy loss (p ¼ 0.008) in external tibial rotation than did men. The results suggest that women may be at greater risk of ACL injury resulting from impingement against the lateral wall of the intercondylar notch, which has been shown to be associated with external tibial rotation and abduction. ß
