Fascia is composed of collagenous connective tissue surrounding and interpenetrating skeletal muscle, joints, organs, nerves, and vascular beds. Fascial tissue forms a whole-body, continuous three-dimensional viscoelastic matrix of structural support. The classical concept of its mere passive role in force transmission has recently been disproven. ⋯ Imbalance of this regulatory mechanism results in increased or decreased myofascial tonus, or diminished neuromuscular coordination, which are key contributors to the pathomechanisms of several musculoskeletal pathologies and pain syndromes. Here, we summarize anatomical and biomechanical properties of fascial tissue with a special focus on fascial dysfunctions and resulting clinical manifestations. Finally, we discuss current and future potential treatment options that can influence clinical manifestations of pain syndromes associated with fascial tissues.

Chronic pain has long been considered an important risk factor for suicidal behavior. Less well understood are the factors associated with the increased risk for suicide death within chronic pain populations. ⋯ However, in all likelihood, there are aspects of chronic pain itself that add uniquely to an individual's suicide risk profile. Lastly, we address a theoretical perspective and offer recommendations for clinical practice.

ReviewAn update on botulinum toxin A injections of trigger points for myofascial pain.
Myofascial pain syndrome (MPS) is a common chronic pain condition that is characterized by distinct "trigger points." Despite current treatments with physical therapy, analgesics, anti-depressants and trigger-point injections, myofascial pain remains a challenging chronic pain condition in clinical practice. Botulinum toxin A (BTX-A) can cause prolonged muscle relaxation through inhibition of acetylcholine release. It may offer some advantages over the current treatments for MPS by providing a longer sustained period of pain relief. ⋯ Eight trials were found according to the above criteria and are summarized in Table 1. There are well-designed clinical trials to support the efficacy of trigger-point injections with BTX-A for MPS. However, further clinical trials with considerations of minimizing placebo effect, repeated dosing, adequate coverage of trigger points, and using ultrasound confirmation and guidance are required to provide conclusive evidence for BTX-A in the treatment of myofascial pain.

Review Historical ArticleHistorical and present state of neuromodulation in chronic pain.
Neuromodulation is based on the revolutionary concept that paresthesia-inducing electrical stimulation could be analgesic. Its historical basis emanates from Melzack and Wall's gate control theory of pain proposed in 1965. Neuromodulation has given us ready access to the systems of pain modulation and helped mature the understanding of the pathophysiology of pain. ⋯ However, the present understanding of pain is rudimentary and evidence that neuromodulation works is modest. This paper emphasizes the historical antecedents, present state, and emerging future of 3 commonly applied neuromodulatory techniques--spinal cord stimulation, peripheral nerve and field stimulation, and deep brain stimulation--for chronic pain. It is hoped this article will enhance the understanding of neuromodulation and its role in pain management.

ReviewPainful connections: densification versus fibrosis of fascia.
Deep fascia has long been considered a source of pain, secondary to nerve pain receptors becoming enmeshed within the pathological changes to which fascia are subject. Densification and fibrosis are among such changes. They can modify the mechanical properties of deep fasciae and damage the function of underlying muscles or organs. ⋯ This review provides an overall description of deep fasciae and the mechanical properties in order to identify the various alterations that can lead to pain. Diet, exercise, and overuse syndromes are able to modify the viscosity of loose connective tissue within fascia, causing densification, an alteration that is easily reversible. Trauma, surgery, diabetes, and aging alter the fibrous layers of fasciae, leading to fascial fibrosis.
