Findings revealed that active and latent MTrPs were prevalent throughout all disorders , however , latent MTrPs did not consistently have a higher prevalence compared to healthy controls .
Conclusions We found limited evidence supporting the high prevalence of active and latent MTrPs in patients with neck or shoulder disorders .
Background Neck and shoulder disorders may be linked to the presence of myofascial trigger points ( MTrPs ) .
These disorders can significantly impact a person ’s activities of daily living and ability to work .
MTrPs can be involved with pain sensitization , contributing to acute or chronic neck and shoulder musculoskeletal disorders .
The aim of this review was to synthesis e evidence on the prevalence of active and latent MTrPs in subjects with neck and shoulder disorders .
Changes in pain and pressure pain sensitivity after manual treatment of active trigger points in patients with unilateral shoulder impingement: a case series.
The aim of this case series was to investigate changes in pain and pressure pain sensitivity after manual treatment of active trigger points ( TrPs ) in the shoulder muscles in individuals with unilateral shoulder impingement . Twelve patients ( 7 men , 5 women , age : 25 ± 9 years ) diagnosed with unilateral shoulder impingement attended 4 sessions for 2 weeks ( 2 sessions/week ) . They received TrP pressure release and neuromuscular interventions over each active TrP that was found . The outcome measures were pain during arm elevation ( visual analogue scale , VAS ) and pressure pain thresholds ( PPT ) over levator scapulae , supraspinatus infraspinatus , pectoralis major , and tibialis anterior muscles . Pain was captured pre-intervention and at a 1-month follow-up , whereas PPT were assessed pre- and post-treatment , and at a 1-month follow-up . Patients experienced a significant ( P < 0.001 ) reduction in pain after treatment ( mean ± SD : 1.3 ± 0.5 ) with a large effect size ( d > 1 ) . In addition , patients also experienced a significant increase in PPT immediate after the treatment ( P < 0.05 ) and one month after discharge ( P < 0.01 ) , with effect sizes ranging from moderate ( d = 0.4 ) to large ( d > 1).A significant negative association ( r(s ) = -0.525 ; P = 0.049 ) between the increase in PPT over the supraspinatus muscle and the decrease in pain was found : the greater the decrease in pain , the greater the increase in PPT . This case series has shown that manual treatment of active muscle TrPs can help to reduce shoulder pain and pressure sensitivity in shoulder impingement . Current findings suggest that active TrPs in the shoulder musculature may contribute directly to shoulder complaint and sensitization in patients with shoulder impingement syndrome , although future r and omized controlled trials are required
