Myofascial pain syndrome (MPS) is described as the sensory, motor, and autonomic symptoms caused by myofascial trigger points (TrPs). Knowing the potential causes of TrPs is important to prevent their development and recurrence, but also to inactivate and eliminate existing TrPs. There is general agreement that muscle overuse or direct trauma to the muscle can lead to the development of TrPs. M...

Recent studies have clarified the nature of myofascial trigger points (MTrPs). In an MTrP region, multiple hyperirritable loci can be found. The sensory components of the MTrP locus are sensitized nociceptors that are responsible for pain, referred pain, and local twitch responses. The motor components are dysfunctional endplates that are responsible for taut band formation as a result of exces...

CONTEXT: Next to dental caries, Myofascial Pain Dysfunction Syndrome (MPDS) is probably the most common cause of chronic facial pain that a dentist treats. However, the combination of multicausality, unknown factors and lack of scientific clinical judgment has produced confusion and controversy. AIMS: The purpose of this study was to evaluate the rate of incidence, predisposing / etiological fa...

Fifty-three patients with a diagnosis of chronic myofascial pain-dysfunction syndrome were treated with occlusal equilibration to establish complete anterior guidance. In approximately 5 to 7 days after treatment, most myofascial pain dysfunction symptoms disappeared and complete symptom resolution was usually attained within 3 weeks. The common symptoms all patients had were (1) pain and fatig...

Fibromyalgia is a chronic syndrome characterized by generalized pain, joint rigidity, intense fatigue, sleep alterations, headache, spastic colon, craniomandibular dysfunction, anxiety, and depression. The purpose of the present study was to determine whether massage-myofascial release therapy can improve pain, anxiety, quality of sleep, depression, and quality of life in patients with fibromya...

BACKGROUND Musculoskeletal pain is a common problem among athletes. Apart from sport injuries, the myofascial pain syndrome is another important problem that affects performance of the athlete. OBJECTIVES The aim of this study was to evaluate the effects of therapeutic sequences of the hot pack in combination with ultrasound on the physiological responses over the latent myofascial trigger po...

Objective: To describe the relationship between viscerosomatic pain syndromes and myofascial pain syndromes [MPS]. Findings: Myofascial pain syndromes can be primary conditions or secondary. When they are secondary, they occur as a manifestation of another disorder. A regional pain referral from a visceral disorder can induce secondary MPS. Visceral disorders induce central sensitization with h...

OBJECTIVE To investigate the comparative treatment effects of ultrasound-guided pulsed radiofrequency treatment (UG-PRF) in the gastrocnemius interfascial space and ultrasound-guided interfascial injection (UG-INJ) on myofascial pain syndrome. METHODS Forty consecutive patients with myofascial pain syndrome of the gastrocnemius were enrolled and were allocated to one of the two groups. Twenty...

OBJECTIVE To evaluate the effect of extracorporeal shock wave therapy (ESWT) in myofascial pain syndrome of upper trapezius with visual analogue scale (VAS) and pressure threshold by digital algometer. METHOD Twenty-two patients diagnosed with myofascial pain syndrome in upper trapezius were selected. They were assigned to treatment and standard care (control) groups balanced by age and sex, ...
