“…The commonly used term 'Tissue Release' in relation to treatment outcomes of muscular imbalances is typically approached from a mechanistic and structural perspective (Schleip 2003). Connective tissue is known to lengthen under static load due to its innate viscoelastic properties; however, this effect is transient and dependent upon duration and mode of stretch (Chaudhry et al 2007;Solomonow, 2009). The palpable phenomenon of a 'Release' that is described by clinicians can be explained by a modification of nociceptive sensation or reflexive changes (Chaudhry et al 2008;Konrad & Tilp 2014;Weppler & Magnusson 2010).…”

In clinical practice, Osteopaths and Manual Therapists commonly direct treatment towards the diaphragm by the use of a 'Diaphragm Release'. Currently, there is paucity within the literature to support the use of this technique, specifically in pain outcomes. This research aims to support a neurophysiological mechanism based upon the osteopathic principle "The body is a unit". Demonstrating that directing treatment to distal tissue which is neurologically related can reduce pain in the originating spinal segments. This study investigated the immediate hypoalgesic effects of a 'Diaphragm Release' on pain pressure thresholds in the cervical spine. A single-blind, randomised, sham-controlled, repeated measures within subject, crossover design was conducted on 17 asymptomatic subjects. Pain pressure thresholds were measured bilaterally in the C4 paraspinal musculature, lateral end of the clavicle and upper third of the tibialis anterior before and after a 'Diaphragm Release'. Results demonstrated a statistically significant hypoalgesic effect was only found in the spinal segment C4 in both the right (p = 0.016) and left (p = 0.004) sides. Averaging the hypoalgesic effect from both sides equates to a 17.17% change which is considered clinically significant, the effect magnitude was calculated to be small but educationally significant for the right (d = 0.26) and left (d = 0.40) sides. This study supports a novel neurophysiological mechanism, Regional Interdependent Inhibition, to induce a hypoalgesic state at segmentally related spinal segments, specifically C4. Suggesting that directing treatment towards the diaphragm, using a 'Diaphragm Release', could induce an immediate clinically and statistically significant hypoalgesic effect local to the fourth cervical segment due to its relationship with the phrenic nerve.

“…Fascia is a strong connective tissue structure formed by an ordered arrangement of collagen fibres playing mainly mechanical and protective functions in an organism. It is an element coordinating muscle motor units and connecting body joints, thus enabling harmonious movement of humans and animals (Chaudhry et al, 2007;). On the functional, morphological, and biochemical levels, disturbances in fascial structures may manifest themselves as a considerable limitation of mobility and often strong pain reactions.…”

The fascial system is an integral part of the musculoskeletal system. It is a three-dimensional network of connective tissue spreading ubiquitously throughout the body, surrounding muscles, bones, internal organs, nerves, vessels, and other structures. The basic biophysical properties of the fascial system are determined by its structure and chemical composition. This study aimed to determine the elemental composition of pathologically unchanged fascia lata of the thigh, collected during autopsies on humans and dogs. The wide spectrum of elements analysed included both macro and micro elements. The analyses were conducted using scanning electron microscopy with X-ray microanalysis (SEM-EDS). Concentrations of the following macro and micro elements were dermined: C, N, O, Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Fe Co, Ni, Cu, and Zn. The obtained results showed significant differences between human and canine fascia lata regarding the content of most of the examined elements (p < 0.05), except for N. These data may in future provide a starting point for the establishment of reference values for the content of various elements in normal fascial tissue and may also serve to verify the usefulness of experimental animal material as a substitute for human tissue.

“…With greater extension in a shorter period of time, greater loads are needed to produce the same strain. The predicted stiffness in extension for plantar fascia, fascia lata and superficial nasal fascia are 404, 477, and 1 MPa respectively (Chaudhry et al, 2007a). We conclude that maximum extension can be achieved with stretch of 60 s and further increasing the duration of the stretch will not increase deformation (Fig.…”

“…We (Chaudhry et al, 2007a) employed the basic field equations for viscoelastic soft tissues to explore the relationship between time-varying mechanical stresses and dynamic deformations of the plantar fascia and fascia lata as well as the softer nasal fascia in manual therapy. The predicted stress range for plastic deformation of plantar fascia, based on the viscoelastic model, was found to be close to experimental findings.…”
