Effect of topical aerosol skin refrigerant (spray and stretch technique) on passive and active stretching.

OBJECTIVES The purpose of this study was to examine the effects of the use of a vapocoolant blend of pentafluoropropane and tetrafluoroethane (Gebauer's Spray and Stretch) on hip flexion stretching. METHODS Thirty volunteers were randomly assigned to spray and stretch treatment and stretch only control groups. Each group was assessed pre- and posttest on passive and active hip flexion range of motion (ROM). RESULTS Findings indicated greater posttest hip flexion gains for the spray and stretch group over the stretch only group for both active and passive ROM. Additionally, females achieved greater pre- and posttest differences on active ROM compared to males. CONCLUSIONS Study findings suggest that spray and stretch techniques can be an effective treatment in increasing hip flexion ROM.
