efficacy in the management of MPS, based on published studies.
Methods: Data sources: PubMed (from 1975), Ovid MEDLINE (from 1975), Ovid
EMBASE (from 1975), the Cochrane Database of Systematic Reviews, AMED
(Alternative Medicine), Science Direct and PEDRO (Physiotherapy Evidence Data-
base), databases were used to the searches.
Study selection: Clinical or Controlled trials in which some form of manual therapy
treatment was used to treat MTrPs.
Data extraction: Two blinded reviewers independently extracted data concerning
trial methods, quality and outcomes.
Quality assessment: Physiotherapy Evidence Database (PEDRO) quality score
method was used in this review.
Results: Data synthesis. 7 studies were included in this review. One manual
therapy treatment was investigated in 4 studies (one of them included a group
treated with manual therapy combined with other physical medicine modalities);
a combination of various manual therapies was investigated in 2 studies, and
manual therapy combined with other physical medicine modality was investigated
in 2 trials.
Quality of the included studies: Two papers obtained 6 points, another two scored
5 points, one scored 3 points, one scored 2 point and the remaining one scored 1
point.
Discussion: Results did not produce any rigorous evidence that some manual
therapies have an effect beyond placebo in treatment of MPS. Some of the studies
reviewed confirmed that MTrP treatment is effective in reducing the pressure pain
threshold, and scores on visual analogue scales. Pressure pain threshold and visual
analogue scale were the outcome measures most used in the analyzed studies. MPS is

include ROM measurements in future studies.
Conclusions: The principal conclusion of this review is that there have been very
few randomized controlled trials that analyse treatment of MPS using manual
therapy. The second conclusion is that the hypothesis that manual therapies have

nor refuted by research to date. Controlled trials are needed to investigate whether
