Myofascial trigger points and innervation zone locations in upper trapezius muscles

Myofascial trigger points and innervation zone locations in upper trapezius muscles

BACKGROUND Myofascial trigger points (MTrPs) are hyperirritable spots located in taut bands of muscle fibres. Electrophysiological studies indicate that abnormal electrical activity is detectable near MTrPs. This phenomenon has been described as endplate noise and it has been purported to be associated MTrP pathophysiology. Thus, it is suggested that MTrPs will be overlap the innervation zone (...

Intra-rater reliability of an experienced physiotherapist in locating myofascial trigger points in upper trapezius muscle.

OBJECTIVES Myofascial trigger points (MTrPs) are considered the principal clinical feature of myofascial pain syndrome (MPS). An MTrP consists of spot tenderness within a taut band of muscle fibers and its stimulation can produce both local and referred pain. The clinical diagnosis of MPS depends on correct history taking and a physical examination aimed at identifying the presence of MTrP. The...

Therapeutic effects of dry needling in patients with upper trapezius myofascial trigger points

BACKGROUND Active myofascial trigger points (MTrPs) are major pain generators in myofascial pain syndrome. Dry needling (DN) is an effective method for the treatment of MTrPs. OBJECTIVE To assess the immediate neurophysiological and clinical effects of DN in patients with upper trapezius MTrPs. METHODS This was a prospective, clinical trial study of 20 patients with upper trapezius MTrPs an...

Predictors of upper trapezius pain with myofascial trigger points in food service workers

Shoulder pain occurs commonly in food service workers (FSWs) who repetitively perform motions of the upper limbs. Myofascial trigger points (MTrPs) on the upper trapezius (UT) are among the most common musculoskeletal shoulder pain syndromes. This study determined the psychological, posture, mobility, and strength factors associated with pain severity in FSWs with UT pain due to MTrPs.In this c...
