The aim of this study was to examine the effect of a single application of muscle energy technique (MET) compared with passive stretch on hip extension range of motion (ROM) over a 30 minute follow-up period. In an experimental repeated measures controlled cross-over trial, 18 healthy males aged between 18 and 45 with a positive Thomas test indicating a restriction in hip extension, were allocated to one of two groups (n=9). Both groups received both the MET and a control procedure (passive stretch) interventions in reverse order to each other with a 7 day interval between sessions. Measurements of passive hip extension in the modified Thomas position were taken immediately prior to and following the intervention, and at 5 minute intervals up until 30 minutes post intervention. The MET intervention produced a “moderate” effect, and the passive stretch produced a “small” effect immediately following the interventions. A “small” effect remained for both groups 30 minutes following the interventions. Therefore both MET and passive stretch appear to be effective in increasing hip extension ROM for a duration of up to 30 minutes.
