Resumen:
Objective: The purpose of this study was to evaluate interrater reliability in the diagnosis of myofascial trigger points
(MTrPs) in the tibialis anterior, peroneus brevis, and extensor digitorum longus muscles.
Methods: A reliability research study was performed. Three physical therapists with clinical experience in myofascial
pain functioned as raters and randomly and bilaterally evaluated the ankles of 40 subjects in the Madrid public health
care system. The absence or presence of MTrPs, nodules in taut bands, patterns of referred pain, local twitch response
(LTR), and jump-sign were evaluated.
Results: We calculated the pairwise interrater agreement and κ-value concordance of the presence or absence of
trigger points (55%-85%; κ = 0.12-0.60), palpable nodules in taut bands (63%-90%; κ = 0.24-0.60), referred pain
(63%-85%; κ = 0.20-0.54), and jump sign (62%-89%; κ = 0.15-0.72) in the 3 studied muscles. The LTR could only be
evaluated in the tibialis anterior (43%-70%; κ = 0.05-0.21), and evaluation was not possible for the other muscles.
Conclusions: Three blinded raters were able to reach acceptable pairwise interrater agreement (percentage of agreement
value ≥70%) for the presence...
