CONTEXT: Chronic musculoskeletal disorders in shoulder joint are often associated with myofascial trigger points (MTrP), particularly in the upper trapezius (UT) muscle. Dry needling (DN) is a treatment of choice for myofascial pain syndrome. However, local lesions and severe post-needle soreness sometimes hamper the direct application of DN in the UT. Therefore, finding an alternative point of treatment seems useful in this regard. OBJECTIVE: To compare the efficacy of UT versus infraspinatus (ISP) DN on pain and disability of subjects with shoulder pain...

BACKGROUND: Myofascial trigger point (MTrP) injection and trigger point dry needling (TrPDN) are widely accepted therapies for myofascial pain syndrome (MPS). Empirical evidence suggests eliciting a local twitch response (LTR) during needling is essential. OBJECTIVE: This is the first review exploring the available literature, regardless of study design, on the neurophysiological effects and clinical significance of the LTR as it relates to reductions in pain and disability secondary to MTrP needling...

BACKGROUND: Myofascial trigger points (MTrP's) are a primary source of pain in patients with musculoskeletal disorders. Nevertheless, they are frequently underdiagnosed. Reliable MTrP palpation is the necessary for their diagnosis and treatment. The few studies that have looked for intra-tester reliability of MTrPs detection in upper body, provide preliminary evidence that MTrP palpation is reliable. Reliability tests for MTrP palpation on the lower limb have not yet been performed. OBJECTIVE: To evaluate inter- and intra-tester reliability of MTrP recognition in hip and thigh muscles...

BACKGROUND: Osteoarthritis (OA) is the most common cause of musculoskeletal pain and disability. The knee is the most common site of OA. Numerous studies have shown an inconsistency between patients' reports of pain and their radiographic findings. This inconsistency may be partially explained by the fact that a portion of the pain originates from the myofascial trigger points (MTrPs) located in the surrounding muscles. AIM: To assess the role of myofascial pain in OA patients...

Objective. : Central sensitization (CS) with low peripheral pain thresholds (PPTs) is a common finding among patients with chronic pain after whiplash (CPWI). While it has been proposed that myofascial myofascial trigger points (MTrPs) may act as modulators of central sensitization, previously reported findings are conflicting and inconclusive. The present study was designed to investigate immediate responsiveness of CS to alterations in nociceptive input. Design.:  Controlled, double-blind, cross-over...
