Dynamic fascial release and the role of mechanical/vibrational assist devices in manual therapies
This review article explores the use of mechanical vibration devices in manual therapy. The author examines several such tools, including percussion vibrators, vibrational platforms, and deep tissue oscillation. The art…
Pandiculation: Nature’s way of maintaining the functional integrity of the myofascial system?
This paper explores the hypothesis that pandiculation—the involuntary stretching and yawning most animals do upon waking—serves a key role for the locomotor system. Beyond preparing the nervous system for wakefulness, t…
Fascia redefined: anatomical features and technical relevance in fascial flap surgery
Fascia has traditionally been seen as a passive wrapping, but this review redefines it as a dynamic tissue with its own complex blood supply and innervation. The authors detail the specific characteristics of different…
Sensory Innervation of the Nonspecialized Connective Tissues in the Low Back of the Rat
In this animal study, researchers investigated the sensory nerves in the nonspecialized connective tissue of the rat low back, an area where knowledge is limited. Using 3D reconstruction and dye-labeling techniques, the…
Fibroblast cytoskeletal remodeling contributes to connective tissue tension
The mechanical properties of connective tissue, such as its elasticity and resistance, have traditionally been attributed to its non-cellular matrix. This study investigated the role of fibroblasts, the cells residing w…
Edema and fluid dynamics in connective tissue remodelling
This review describes the role of loose connective tissues, focusing on fluid exchange across capillaries and the formation of edema (swelling). This process is relevant for conditions like inflammation, fibrosis (scarr…
3D reconstruction of the crural and thoracolumbar fasciae
Researchers created detailed 3D computer models to visualize the structure of the crural fascia in the lower leg and the superficial layer of the thoracolumbar fascia in the lower back. They found the crural fascia is c…
