“…Like the extramuscular tendon portion, the aponeurosis is a collagenous structure and deforms upon load application in a predictable nonlinear manner (Huijing & Ettema, 1988\1989 ;Ettema & Huijing, 1989 ;Lieber et al 1991 ;Trestik & Lieber, 1993 ;Zuurbier et al 1994 ;Scott & Loeb, 1995 ;Maganaris & Paul, 2000 a).…”

“…In in vitro experiments the epimysium has been removed to eliminate artifactual marker displacements (Zuurbier et al 1994 ;Scott & Loeb, 1995 ;van Donkelaar et al 1999). Epimysial release, however, reduces the pressure and the force generated in the muscle during contraction (Mozan & Keagy, 1969 ;Garfin et al 1981).…”

Changes in aponeurotic dimensions upon muscle shortening: in vivo observations in man

Aponeurotic deformation measurements have traditionally been taken by loading dissected muscles ; thus the values obtained may not reflect in vivo function. In the present study, we estimated dimensional changes in the central aponeurosis of the intact human tibialis anterior muscle upon loading induced by muscle contraction. Measurements were taken in seven males, and involved real-time ultrasound scanning of the tibialis anterior muscle at 30m of plantarflexion at rest and during isometric dorsiflexion maximum voluntary contraction (MVC). At each contraction state, the length of the aponeurosis, the width along its length, and its area were estimated from sagittal-plane and axial-plane sonographs. In the transition from rest to MVC, the length of the aponeurosis increased by 7 % (P 0n05), its width increased by up to 21 % (P 0n05), and its area increased by 17 % (P 0n05). These results indicate that the in vivo tibialis anterior aponeurosis behaves as a compliant material upon active muscle shortening. The methodology employed allows crosssectional and longitudinal design investigations, circumventing the problems associated with epimysial removal under in vitro experimental conditions.

“…Therefore any collection of three muscle elements arranged in series represents a big muscle fascicle. All aponeurosis elements have identical mechanical properties but using a variable thickness in the fiber-cross fiber plane, the increasing cross-sectional area of the aponeurosis toward the tendon (Zuurbier et al 1994) is accounted for.…”

Finite element modeling of aponeurotomized rat extensor digitorium longus muscle was performed to investigate the acute effects of proximal aponeurotomy. The specific goal was to assess the changes in lengths of sarcomeres within aponeurotomized muscle and to explain how the intervention leads to alterations in muscle length-force characteristics. Major changes in muscle length-active force characteristics were shown for the aponeurotomized muscle modeled with (1) only a discontinuity in the proximal aponeurosis and (2) with additional discontinuities of the muscles' extracellular matrix (i.e., when both myotendinous and myofascial force transmission mechanisms are interfered with). After muscle lengthening, two cut ends of the aponeurosis were separated by a gap. After intervention (1), only active slack length increased (by approximately 0.9 mm) and limited reductions in muscle active force were found (e.g., muscle optimum force decreased by only 1%) After intervention (2) active slack increased further (by 1.2 mm) and optimum length as well (by 2.0 mm) shifted and the range
