Background: Retinacula of the ankle are thickening of the deep fascia of the leg (crural fascia) and foot i.e. inseparable structures. Recent studies report their crucial role in functional stability and proprioception of the ankle. Case presentation: A 38-yr-old Caucasian man - with a history of lateral malleolus fracture 12 years ago, obesity and right ankle osteoarthritis - was referred to a physiatrist for a right ankle pain that had significantly worsened over the last year. During walking, the patient experienced stinging pain in the area of tibialis anterior and peroneus tertius muscles, and the superior extensor retinaculum. Magnetic resonance imaging and ultrasonography showed clear thicknening (2.05 mm) of the oblique superomedial band of the inferior extensor retinaculum. Sonopalpation was performed to precisely evaluate/confirm the site of maximum pain. Foot function index (FFI) score was 42. Results: Subsequently, the patient was prescribed fascial manipulation, and he had clinical improvement after the first session (FFI: 21). At 1-month follow-up, the patient was still asymptomatic without any functional limitation (FFI: 24). US imaging confirmed the decreased thickness of the oblique superomedial band of the extensor retinaculum (1.35 mm). Conclusion: Fascial Manipulation® appears to be a useful tool to reduce thickness, stiffness, and pain in this case as displayed by the ultrasound Imaging.

The International Symposium on Myofascial Pain, Fibromyalgia, and Fascial Pain Disorders was held at the University of Padua, Padua, Italy in June of 2023. This report presents a summary of the presentations from scientists and clinicians from around the world who presented to the symposium. The purpose of this symposium and resultant paper is improve health professional's recognition and understanding of the clinical characteristics, co-morbidities, mechanisms, and treatment strategies for these common conditions to better understand and manage their pain, dysfunction, and quality life.

PURPOSE/OBJECTIVE:Fascial changes in hypermobile Ehlers-Danlos syndrome (hEDS), a heritable connective tissue disorder, can be used visualized with sonoelastography. The purpose of this study was to explore the inter-fascial gliding characteristics in hEDS. METHODS:In 9 subjects, the right iliotibial tract was examined with ultrasonography. Tissue displacements of the iliotibial tract were estimated from ultrasound data using cross-correlation techniques. RESULTS:In hEDS subjects, shear strain was 46.2%, lower than those with lower limb pain without hEDS (89.5%) and in control subjects without hEDS and without pain (121.1%). CONCLUSION/CONCLUSIONS:Extracellular matrix changes in hEDS may manifest as reduced inter-fascial plane gliding.

It is a common experience, reported by patients who have undergone manual therapy that uses deep friction, to perceive soreness in treatment areas; however, it is still not clear what causes it and if it is therapeutically useful or a simple side effect. The purpose of this narrative review is to determine whether manual and physical therapies can catalyze an inflammatory process driven by HA fragments. The literature supports the hypothesis that mechanical stress can depolymerize into small pieces at low molecular weight and have a high inflammatory capacity. Many of these pieces are then further degraded into small oligosaccharides. Recently, it has been demonstrated that oligosaccharides are able to stop this inflammatory process. These data support the hypothesis that manual therapy that uses deep friction could metabolize self-aggregated HA chains responsible for increasing loose connective tissue viscosity, catalyzing a local HA fragment cascade that will generate soreness but, at the same time, facilitate the reconstitution of the physiological loose connective tissue properties. This information can help to explain the meaning of the inflammatory process as well as the requirement for it for the long-lasting resolution of these alterations.

BACKGROUND:This study aimed to investigate the effect of fascial manipulation (FM) of the deep cervical fascia (DCF) and sequential yoga poses (SYP) on pain and function in individuals with mechanical neck pain (MNP). METHOD/METHODS:Following the predefined criteria, ninety-nine individuals with MNP were recruited, randomised, and assigned to either the intervention group (IG) (n = 51) or the control group (CG) (n = 48). Individuals in the IG received FM (4 sessions in 4 weeks) and the home-based SYP (4 weeks). The CG participants received their usual care (cervical mobilisation and thoracic manipulation (4 sessions in 4 weeks) along with unsupervised therapeutic exercises (4 weeks). The participants underwent baseline and weekly follow-up measurements of pain using a numerical pain rating scale (NPRS) and elbow extension range of motion (EEROM) during the upper limb neurodynamic test 1 (ULNT1). The baseline and the fourth session follow-up measurements of the patient-specific functional scale (PSFS) and fear-avoidance behavior Questionnaire (FABQ) were also taken. RESULTS:< 0.001), but there were no significant differences in PSFS between the groups during the follow-up. CONCLUSION/CONCLUSIONS:FM and SYP can aid in reducing pain and fear-avoidance behaviour and improve the function and extensibility of the upper quarter region.

BACKGROUND:Myofascial Pain Syndrome (MPS) is a common pain disorder. Diagnostic criteria include physical findings which are often unreliable or not universally accepted. A precise biosignature may improve diagnosis and treatment effectiveness. The purpose of this study was to assess whether microanalytic assays significantly correlate with characteristic clinical findings in people with MPS. METHODS:This descriptive, prospective study included 38 participants (25 women) with greater than 3 months of myofascial pain in the upper trapezius. Assessments were performed at a university laboratory. The main outcome measures were the Beighton Index, shoulder range of motion, strength asymmetries and microanalytes: DHEA, Kynurenine, VEGF, interleukins (IL-1b, IL-2, IL-4, IL-5, IL-7, IL-8, IL-13), growth factors (IGF-1, IGF2, G-CSF, GM-CSF), MCP-1, MIP-1b, BDNF, Dopamine, Noradrenaline, NPY, and Acetylcholine. Mann-Whitney test and Spearman's multivariate correlation were applied for all variables. The Spearman's analysis results were used to generate a standard correlation matrix and heat map matrix. RESULTS:Mean age of participants was 32 years (20-61). Eight (21%) had widespread pain (Widespread Pain Index ≥ 7). Thirteen (34%) had MPS for 1-3 years, 14 (37%) 3-10 years, and 11 (29%) for > 10 years. The following showed strong correlations: IL1b,2,4,5,7,8; GM-CSF and IL 2,4,5,7; between DHEA and BDNF and between BDNF and Kynurenine, NPY and acetylcholine. The heat map analysis demonstrated strong correlations between the Beighton Index and IL 5,7, GM-CSF, DHEA. Asymmetries of shoulder and cervical spine motion and strength associated with select microanalytes. CONCLUSION/CONCLUSIONS:Cytokine levels significantly correlate with selected clinical assessments. This indirectly suggests possible biological relevance for understanding MPS. Correlations among some cytokine clusters; and DHEA, BDNF kynurenine, NPY, and acetylcholine may act together in MPS. These findings should be further investigated for confirmation that link these microanalytes with select clinical findings in people with MPS.

The "motor unit" or the "muscle" has long been considered the quantal element in the control of movement. However, in recent years new research has proved the strong interaction between muscle fibers and intramuscular connective tissue, and between muscles and fasciae, suggesting that the muscles can no longer be considered the only elements that organize movement. In addition, innervation and vascularization of muscle is strongly connected with intramuscular connective tissue. This awareness induced Luigi Stecco, in 2002, to create a new term, the "myofascial unit", to describe the bilateral dependent relationship, both anatomical and functional, that occurs between fascia, muscle and accessory elements. The aim of this narrative review is to understand the scientific support for this new term, and whether it is actually correct to consider the myofascial unit the physiological basic element for peripheral motor control.

Low back pain (LBP) is the leading cause of disability worldwide. Most LBP is non-specific or idiopathic, which is defined as symptoms of unknown origin without a clear specific cause or pathology. Current guidelines for clinical evaluation are based on ruling out underlying serious medical conditions, but not on addressing underlying potential contributors to pain. Although efforts have been made to identify subgroups within this population based on response to treatment, a comprehensive framework to guide assessment is still lacking. In this paper, we propose a model for a personalized mechanism-based assessment based on the available evidence that seeks to identify the underlying pathologies that may initiate and perpetuate central sensitization associated with chronic non-specific low back pain (nsLBP). We propose that central sensitization can have downstream effects on the "myofascial unit", defined as an integrated anatomical and functional structure that includes muscle fibers, fascia (including endomysium, perimysium and epimysium) and its associated innervations (free nerve endings, muscle spindles), lymphatics, and blood vessels. The tissue-level abnormalities can be perpetuated through a vicious cycle of neurogenic inflammation, impaired fascial gliding, and interstitial inflammatory stasis that manifest as the clinical findings for nsLBP. We postulate that our proposed model offers biological plausibility for the complex spectrum of clinical findings, including tissue-level abnormalities, biomechanical dysfunction and postural asymmetry, ecological and psychosocial factors, associated with nsLBP. The model suggests a multi-domain evaluation that is personalized, feasible and helps rule out specific causes for back pain guiding clinically relevant management. It may also provide a roadmap for future research to elucidate mechanisms underlying this ubiquitous and complex problem.

Complex regional Pain Syndrome (CRPS) is a complex disease with articulate impact on the quality of life and its management is challenging. Ultrasound imaging can identify/assess different musculoskeletal structures that might have role in its pathogenesis. We present two cases of CRSP in whom B-mode ultrasonography and sonoelastography showed rigid retinacula associated with the symptomatology. Both patients were also/successfully treated with Fascial Manipulation®.
