Experimental approach to the problem
BLIND
In a double‐blind controlled design, we tested the effects of a NT single session on hip ROM and H‐reflex excitability in asymptomatic young subjects. Based on previous reports, our hypothesis establishes that NT will increase ROM and H‐reflex amplitude (Castellote‐Caballero et al., The effects NT on H‐reflex and ROM were studied in six groups of 10 subjects receiving different interventions on the sciatic nerve. Subjects were pseudo‐randomly assigned to one of the six study groups, with balanced proportion of men and women, by using EpiInfo software. Subjects were unaware of the existence of different groups and the specific objective of the study.Investigators (blind to the group assignment) carried out the neurophysiological evaluations and ROM, in this order, at three different time‐points: Interventions and evaluations were always performed on the subject's dominant limb, defined as: “the leg used to kick a ball” (Kovaleski et al.,
