“…To enable comparison of muscle forces, muscle forces were expressed as absolute values as well as a percentage of their maximum. The maximum muscle forces were based on a force of 100N/cm 2 of the physiologic cross-sectional area and obtained from Veeger et al 17,18 In our study, the lesion level was not simulated in the model by reducing muscle force in paralyzed muscles; therefore, all the muscles in the model could be used to balance the external moments. Because more force in the remaining muscles would be needed to balance the external moment, the predicted muscle forces would likely be underestimated.…”

ABSTRACT. van Drongelen S, van der Woude LH, Janssen TW, Angenot EL, Chadwick EK, Veeger DH. Glenohumeral contact forces and muscle forces evaluated in wheelchair-related activities of daily living in able-bodied subjects versus subjects with paraplegia and tetraplegia. Arch Phys Med Rehabil 2005;86: 1434-40.Objective: To estimate the differences in glenohumeral contact forces and shoulder muscle forces between able-bodied subjects and subjects with paraplegia and tetraplegia during wheelchair-related activities of daily living (ADLs).Design: Kinematics and external forces were measured during wheelchair ADLs (level propulsion, weight-relief lifting, reaching) and processed by using an inverse dynamics 3-dimensional biomechanical model.Setting: Biomechanics laboratory. Participants: Five able-bodied subjects, 8 subjects with paraplegia, and 4 subjects with tetraplegia (Nϭ17).Interventions: Not applicable. Main Outcome Measures: Glenohumeral contact forces and shoulder muscle forces.Results: Peak contact forces were significantly higher for weight-relief lifting compared with reaching and level propulsion (PϽ.001). High relative muscle force of the rotator cuff was seen, apparently needed to stabilize the joint. For weight-relief lifting, total relative muscle force was significantly higher for the tetraplegia group than for the able-bodied group (Pϭ.022).Conclusions: Glenohumeral contact forces were significantly higher for weight-relief lifting and highest over the 3 tasks for the tetraplegia group. Without taking paralysis into account, more muscle force was estimated for the subjects with tetraplegia during weight-relief lifting.

“…Some superficial soft tissues were removed; however, the origin and insertions of the deltoid muscle, rotator cuff muscles, both heads of the biceps, and the glenohumeral capsule were preserved. Number 2 Ethibond 1 sutures (Ethicon Inc, Somerville, NJ, USA) were placed into the tendons of the three heads of the deltoid, supraspinatus, infraspinatus, teres minor, subscapularis, the conjoint group, and the long head of the biceps to allow the application of physiologic loads via the shoulder instability simulator [10,11,13,14,23,25].…”

“…The nine sutured tendons were passed through alignment guides to ensure physiologic force vectors and connected to computer-controlled pneumatic actuators (Airpot Co, Norwalk, CT, USA). The conjoint tendon was loaded with 10 N and the supraspinatus, subscapularis, and the combination of the infraspinatus and teres minor were all loaded with 7.5 N each [10,11,13,14,23,25]. The anterior, lateral, and posterior heads of the deltoid muscle were each loaded with 5 N [11,18,23,25].…”

“…Previous authors have measured muscle architecture (Amis et al, 1979;Bassett et al, 1990;Veeger et al, 1991Veeger et al, , 1997 and moment arms (Otis et al, 1994;Kuechle et al, 1997Kuechle et al, , 2000Hughes et al, 1998) at the shoulder. Due to parameter variability and covariance, it is advantageous to measure parameters in conjunction with one another, rather than to use parameters from different data-sets (Hoffer et al, 1989;Hoy et al, 1990;Loren et al, 1996).…”

Background. Muscles which cause glenohumeral external rotation possess varying ability for generating force and moment due to differences in muscle architecture, moment arm, and the interaction of these two factors. This study's purpose was to determine a complete dataset of muscletendon parameters for predicting the moment generating capacity and force-length dependence for external rotation of infraspinatus, supraspinatus and teres minor muscles.Methods. Muscle fascicle length, sarcomere length, pennation angle, and muscle volume were measured for sub-regions of infraspinatus and supraspinatus, and teres minor from 10 glenohumeral specimens. Tendon excursion was measured for glenohumeral rotation. From these parameter measurements, optimal fascicle length, physiological cross-sectional area, muscle force-length dependence, and maximum isometric moment generating capacity were calculated.Findings. Substantial differences were found for optimal muscle length, physiologic cross-sectional area, and tendon length for the 10 specimens of this study. Muscle sub-region had a significant effect on the force-length relationship for infraspinatus (P < 0.001), but was not significant for supraspinatus (P = 0.49). For infraspinatus and supraspinatus, maximum isometric rotation moment capacity was greater at 10° versus 60° abduction (P < 0.001). Maximum isometric rotation moment capacity for the teres minor was greater at 10° versus 60° abduction (P < 0.01). Sub-regions demonstrated significant differences in isometric moment capacity (P < 0.001).Interpretation. Functional capabilities of these muscles depend on muscle architecture and moment arm as well as their combined effects. The results allow for development of stochastic and deterministic models of glenohumeral external rotation strength which can be used for prediction of muscle forces and joint moments.
