Acute Effects of Percussive Massage Therapy on Thoracolumbar Fascia Thickness and Ultrasound Echo Intensity in Healthy Male Individuals: A Randomized Controlled Trial.

Percussive massage therapy (PT) has been widely used by therapists and the fitness population to treat myofascial-related conditions. However, there is no evidence to confirm the effects of PT on the fascia. This study aimed to investigate the effects of PT on thoracolumbar fascia (TLF) morphology and other related outcomes. METHODS: Sixty-six healthy males participated and were randomly allocated into a percussive massage group (PT group) and a control group. The PT group received 15 min of back percussion massage, while the control group rested prone lying in the same environment for 15 min. Thoracolumbar fascia (TLF) thickness and echo intensity, perceived stiffness, lumbar flexibility, and skin temperature were measured in both groups before and immediately after the intervention. RESULT: TLF thickness and lumbar flexibility did not change when compared in the two groups. However, the echo intensity (left side, difference -3.36, 95% CI -5.1 to -1.6; right side, difference -4.39, 95% CI -6.1 to -2.7) and perceived stiffness (difference, -1.18, 95% CI -1.84 to -0.52) in the TLF region were significantly lower in the PT group than in the control group and were accompanied by increased skin temperature (difference 0.29, 95% CI 0.11 to 0.48). CONCLUSION: We suggest that a 15 min PT with 30 Hz on the back region could reduce TLF echo intensity and perceived stiffness and increase skin temperature in healthy men individual.

[Anatomical revivification of the structure of the belt vessel].

On the base of the records in Huangdi Neijing (Yellow Emperor 's Inner Classic) and relevant ancient literature, the anatomical structure of the belt vessel was revivified. The belt vessel covers the kidneys and inlays in the 14th vertebrae on the lumbar region. It joints qijie (qi street) at the groin and connects with the thoroughfare vessel, the conception vessel and the governor vessel, as well as the muscle region of foot-yangming meridian. Correspondingly, the related anatomic structure includes renal fascia and transversalis fascia. The transversalis fascia is the main part of the belt vessel structure. The superior lumbar triangle is the vulnerable spot of abdominal wall structure and also coincident with the localization of "3 cun away from the spinal column bilaterally". It is the optimal selection when stimulating the belt vessel. In late generations, "governing all of meridians" has been supplemented as the function of the belt vessel. The diaphragm extends to the transversalis fascia and renal fascia through the inferior diaphragmatic fascia and it is also the only structure that connects with the twelve meridians and five zang organs. Hence, modern acupuncture and moxibustion has actually transferred the structural center of the belt vessel from the transversalis fascia to the diaphragm.

Ultrasonography Comparison of the Plantar Fascia and Tibialis Anterior in People With and Without Lateral Ankle Sprain: A Case-Control Study.

OBJECTIVE: The purpose of the present study was to evaluate the thickness of the plantar fascia (PF) at the insertion of the calcaneus and the midfoot and forefoot fascial locations, in addition to the thickness of the tibialis anterior, by ultrasound imaging in individuals with and without lateral ankle sprain (LAS). METHODS: A sample of 44 participants was recruited and divided in 2 groups: 22 feet with a prior diagnosis of grade 1 or 2 LAS (case group) and 22 feet without this condition (healthy group). The thickness and cross-sectional area were evaluated by ultrasound imaging in both groups. RESULTS: Ultrasound measurements of the PF at the calcaneus, midfoot, and forefoot showed statistically significant differences (P < .05), with a decrease in thickness in the LAS group relative to the healthy group. For the thickness and cross-sectional area of the tibialis anterior, no significant differences (P < .05) were observed between groups. CONCLUSION: The thickness of the PF at the calcaneus, midfoot, and forefoot is reduced in individuals with LAS relative to the healthy group.

Can Myofascial Interventions Have a Remote Effect on ROM? A Systematic Review and Meta-Analysis.

CONTEXT: Anatomical and in vivo studies suggest that muscles function synergistically as part of a myofascial chain. A related theory is that certain myofascial techniques have a remote and clinically important effect on range of motion (ROM). OBJECTIVE: To determine if remote myofascial techniques can effectively increase the range of motion at a distant body segment. EVIDENCE ACQUISITION: In November 2018, the authors searched 3 electronic databases (CENTRAL, MEDLINE, and PEDro) and hand-searched journals and conference proceedings. Inclusion criteria were randomized controlled trials comparing remote myofascial techniques with passive intervention (rest/sham) or local treatment intervention. The primary outcome of interest was ROM. Quality assessment was performed using the PEDro Scale. Three authors independently evaluated study quality and extracted data. RevMan software was used to pool data using a fixed-effect model. EVIDENCE SYNTHESIS: Eight randomized controlled trials, comprising N = 354 participants were included (mean age range 22-36 y; 50% female). Study quality was low with PEDro scores ranging from 2 to 7 (median scores 4.5/10). None of the studies incorporated adequate allocation concealment and just 2 used blinded assessment of outcomes. In all studies, treatments and outcomes were developed around the same myofascial chain (superficial back line). Five studies included comparisons between remote interventions to sham or inactive controls; pooled results for ROM showed trends in favor of remote interventions (standard mean difference 0.23; 95% confidence intervals; -0.09 to 0.55; 4 studies) at immediate follow-ups. Effects sizes were small, corresponding to mean differences of 9% or 5° in cervical spine ROM, and 1 to 3 cm in sit and reach distance. Four studies compared remote interventions to local treatments, but there were few differences between groups. CONCLUSIONS: Remote exercise interventions may increase ROM at distant body segments. However, effect sizes are small and the current evidence base is limited by selection and measurement bias.

Comparison of Myofascial Release Techniques on Pectoralis Minor Length, Glenohumeral Total Arc of Motion, and Skin Temperature: A Pilot Study.

CONTEXT: The pectoralis minor (PM) is an important postural muscle that may benefit from myofascial techniques, such as Graston Technique® (GT) and self-myofascial release (SMR). OBJECTIVE: To examine the effects of GT and SMR on PM length, glenohumeral total arc of motion (TAM), and skin temperature. DESIGN: Cohort. SETTING: Laboratory. PARTICIPANTS: Twenty-six healthy participants (19 females and 7 males; age = 20.9 [2.24] y, height = 170.52 [8.66] cm, and weight = 72.45 [12.32] kg) with PM length restriction participated. INTERVENTIONS: Participants were randomized to the intervention groups (GT = 12 and SMR = 14). GT and SMR interventions were both applied for a total of 5 minutes during each of the 3 treatment sessions. MAIN OUTCOME MEASURES: PM length, TAM, and skin temperature were collected before and after each intervention session (Pre1, Post1, Pre2, Post2, Pre3, and Post3) and at 1-week follow-up (follow-up). Separate intervention by time analyses of variance examined differences for each outcomes measure. Bonferroni post hoc analyses were completed when indicated. Significance was set a priori at P ≤ .05. RESULTS: No significant intervention by time interactions were identified for PM length, TAM, or temperature (P > .05). No significant intervention main effects were identified for PM length (P > .05), TAM (P > .05), or temperature (P > .05) between the GT or SMR technique groups. Overall, time main effects were found for PM length (P = .02) and temperature (P < .001). Post hoc analysis showed a significant increase in PM length for both intervention groups at follow-up (P = .03) compared with Post2. Furthermore, there were significant increases in temperature at Post1 (P < .001), Post2 (P = .01), and Post3 (P < .001) compared with Pre1; Post2 was increased compared with Pre2 (P = .003), Pre3 (P < .001), and follow-up (P = .01); Post3 increased compared with Pre3 (P = .01) and follow-up (P = .01). CONCLUSION: Serial application of GT and SMR to the PM did not result in increases in PM length or TAM. Regardless of intervention, skin temperature increased following each intervention.

Improving the New Definition of Fascial System.

BACKGROUND/AIMS: Bone tissue is defined as connective tissue with an embryological derivation that reflects the origin of the fascial system. The surface of the bone tissue makes the bone system the largest organ in the human body, whose most representative cells are the osteocytes. It is essential for the general health of the individual, influencing different organs and systems, through the hormonal paracrine production of the osteocytes. In the modern scientific panorama, bone tissue has been included in the definition of fascial continuum only in one of our articles. The intent of this article is to enrich the motivations that led to the introduction of the bone in the fascia description, illustrating its local and systemic properties. The final theme of the current text will be to give a definition of the fascial system more congruent with modern scientific notions. METHODS: The article collects the embryological and anatomical information on bone and exposes the most recent information in a narrative review. RESULTS: The results of the literature show that bone is specialized connective tissue. CONCLUSION: Bone tissue must be included in the definitions of what is considered fascial tissue, so as to have a better view of the fascial system.

Frontiers in fascia research.

Basic sciences are the backbone of every clear understanding of how the body is composed and how different structures and functions are connected with each other. It is obvious that there is a huge variability in human beings - not only in terms of the outer appearance such as measurements of height, weight, muscle mass and other physical properties, but also with respect to metabolic and functional parameters. This article highlights recent developments of research activities in the field of fascia sciences with a special emphasis on assessment strategies as the basis of further studies. Anatomical and histological studies show that fascial tissue is highly variable in terms of density, stiffness, and other parameters such as metabolic and humoral activity. Moreover, it encompasses nerves and harbours a system of micro-channels, also known as the primo vascular system. As ultrasound is a widely available method, its use is appealing not only for imaging of fascial structures, but also for thorough scientific analysis. Unlike most other imaging technologies, US has the advantage of real-time analysis of active or passive movements. In addition, other assessment methods for fascial tissue are discussed. In conclusion, fascial tissue plays an important role not only in functional anatomy, but also in evolutionary and molecular biology, sport, and exercise science as well as in numerous therapeutic approaches. A high density of nerves is found in fascial tissue. Knowledge of individual characteristics, especially by visualizing with ultrasound, leads to personalized therapeutic approaches, such as in pain therapy.

Defining the fascial system.

Fascia is a widely used yet indistinctly defined anatomical term that is concurrently applied to the description of soft collagenous connective tissue, distinct sections of membranous tissue, and a body pervading soft connective tissue system. Inconsistent use of this term is causing concern due to its potential to confuse technical communication about fascia in global, multiple discipline- and multiple profession-spanning discourse environments. The Fascia Research Society acted to address this issue by establishing a Fascia Nomenclature Committee (FNC) whose purpose was to clarify the terminology relating to fascia. This committee has since developed and defined the terms a fascia, and, more recently, the fascial system. This article reports on the FNC's proposed definition of the fascial system.

Fascial hierarchies and the relevance of crossed-helical arrangements of collagen to changes in shape; part II: The proposed effect of blood pressure (Traube-Hering-Mayer) waves on the fascia.

Periodic changes in arterial pressure and volume have long been related to respiratory and sympathetic nerve activity (Traube-Hering-Mayer waves) but their origins and nomenclature have caused considerable confusion since they were first discovered in the eighteenth century. However, although they remain poorly understood and the underlying details of their control are complicated, these waves do provide valuable clinical information on the state of blood pressure regulation in both normal and pathological conditions; and a correlation with oscillatory motions observed by certain practitioners suggests that they may also have some physiological value that relates to changes in the volume of fascial 'tubes'. Part I of this paper (Scarr, 2016) described a complex fascial network of collagen-reinforced tubular sheaths that are an integral part of muscle structure and function, and continuous with 'higher-level' fascial tubes surrounding groups of muscles, the limbs and entire body. The anisotropic arrangements of collagen fibres within the walls of these tubes reflect the most efficient distribution of mechanical stresses and have been considered to coordinate changes in shape, and a proposed link between cyclic variations in arterial pressure and volume, and the behaviour of these fascial compartments is now described.

[Effects of acupuncture with different filiform needles on tissues, cells and collagenous fiber of fascia in acupoint area of rats].

OBJECTIVE: To explore the effects of acupuncture with different filiform needles on structure of fascial connective tissues, cellular activity, arrangement and content of collagen fibers in acupoint area of rats. METHODS: A total of 32 SD rats were randomly divided into a blank group, a thin needle group, a medium needle group and a thick needle group, 8 rats in each one. Except for the blank group, rats in the remaining groups were treated with horizontal acupuncture at "Zhongwan" (CV 12) towards Conception Vessel with different filiform needles, and twirling mild reinforcing-reducing method was applied, once a day. Rats in the blank group were treated with identical anesthesia, grasping and fixation. After 3-day intervention, the fascial connective tissue of acupoint area was collected. HE staining, immumohistochemical staining of proliferating cell nuclear antigen (PCNA) and MASSON staining were adopted to observe the morphology of fascial connective tissues, expression of PCNA in cells and arrangement and expression of collagenous fiber. RESULTS: After acupuncture in each group, the consistency of morphology of fascial connective tissues and arrangement of collagenous fiber were changed; the expression of PCNA protein in the fascial connective tissue in each group was significantly increased (P<0. 01, P<0. 05). The area distribution of collagenous fiber were changed, and that in the thin needle group was insignificantly increased compared with that in the blank group (P>0. 05), and that in the medium needle group and thick needle group were reduced compared with that in the blank group (both P<0. 05). CONCLUSIONS: Acupuncture with different filiform needles can change the local tissue morphology of acupoints, strengthen cell activity and adjust the exyression of collagenous fiber protein, which may be one of the cellular biomechanics principles of the acupuncture therapy's "regulating meridians" effects. However, the stimulation is produced by different fifiform needles, and the complex relationships exist between cells and collagen fibers.

Reliability and Validity of Transversus Abdominis Measurement at the Posterior Muscle-Fascia Junction with Ultrasonography in Asymptomatic Participants.

OBJECTIVE: The purposes of this study were (1) to establish the intrarater sliding and change in thickness of the transversus abdominis (TrA) measurement at the posterior muscle-fascia junction and (2) to examine the relationship between the muscle thickness and sliding of the TrA at the anterior and posterior sites. METHODS: Asymptomatic participants (n = 20) were placed into the hook-lying position to perform the abdominal drawing-in maneuver viewed in B-mode with a 5- to 12-MHz linear ultrasound transducer. The outcome variables included the resting thickness, the thickness during contraction, the change of thickness, and the change of sliding length. Both intraclass correlation coefficient and Pearson correlation were used for analysis. RESULTS: Measuring the thickness and sliding of the TrA at the posterior muscle-fascia junction showed good reliability (intraclass correlation coefficient (3,3), 0.89-0.98). The correlations between the sliding measurements of the TrA at the anterior and posterior sites were moderate to good (r = 0.41-0.74). CONCLUSION: This study found that measuring the musculofascial corset from the posterior site using ultrasonography is reliable, allowing for ultrasound measurements at both the anterior and posterior sites of the TrA to provide a comprehensive evaluation of the TrA fascia.

Fascial eponyms may help elucidate terminological and nomenclatural development.

It has been reported that at least 700 anatomical eponyms were in existence at the end of the 19th century, yet the number of eponyms expressly relating to fasciae is unknown, and these anatomical expressions have yet to be described as a group. This study accordingly aimed to assemble a comprehensive-as-possible list of these terms, to investigate their customary usage, and to consider whether their existence might usefully shed light on contemporary fascia-relating terminological development. A search for fascia-relating eponyms incorporated within a range of English language anatomical and medical publications during the past 400 years resulted in the discovery of 44 eponyms that explicitly refer to aspects of fascia. This article outlines and discusses the origin, meaning, and use of these terms, and concludes that an understanding of the history of fascial eponyms may be of value when addressing contemporary concerns with the language used to describe fascia.

Natale et. al.'s response to Stecco's fascial nomenclature editorial.

Despite their importance in anatomy, physiology, pathology and surgery, the fasciae and the fascial spaces have been poorly described in classic textbooks. This little attention depends on the fact that these fasciae vary in thickness and composition, especially at the cervical level. Indeed, in the main literature they have been described in different forms. Furthermore, the definition itself of the fascia is not consistent in a variety of authors. As a consequence, different criteria have been used to define and classify the fascial systems. In this paper, a brief terminological history and the most common nomenclatures and classifications of the fascia have been summarized.
