The aim of this study was to determine the influence of expectations plus mobilization with movement (MWM) in kinesiophobia, perceived disability and sensorimotor variables in patients with lateral epicondyl-algia. A pilot randomized controlled trial in 24 patients with lateral epi-condylalgia was conducted. Perceived pain, pain-free grip strength, pressure pain detection threshold, kinesiophobia measured with the short version of Tampa Scale of Kinesiophobia, perceived disability of the upper limb measured with disability of the arm, hand and shoulder questionnaire, and perceived disability specifically for the elbow joint measured with patient-rating tennis elbow evaluation, and also satis-faction were assessed. Participants were randomized to receive writ-ten instructions in order to create positive expectations regarding the technique in one group (n=12) or neutral expectations in the other one (n=12). All patients were treated for three sessions with the MWM technique. Measures were recorded before and after treatment. The effect size was calculated by Rosenthal “r” for nonparametrical tests. There were no significant statistical differences (P>0.05) between groups after receiving the treatment for none of the physical analyzed variables. The Wilcoxon test showed statistically significant changes in kinesiophobia (Z=-2.278, r=0.47, P=0.023) and perceived disability (Z= -2.934, r=0.61, P=0.003) within positive expectations group. In conclu-sion this pilot study shows that a positive expectation almost given in a sealed envelope before treatment plus MWM produced changes in ki-nesiophobia and perceived disability in the immediate term, in patients with lateral epicondylalgia.
