Effect of Fluori-Methane spray on passive hip flexion

The purpose of the study was to evaluate the influence of Fluori-Methane spray as a method of affecting passive range of motion measured at the right hip joint. Subjects were 30 normal volunteers randomly divided into an experimental group and a control group. A special table was constructed to position and stabilize each subject for monitoring the right lower extremity's resistance to side-lying straight leg raising. Specific right hip flexion goniometric measurements were compared and analyzed before and after application of Fluori-Methane spray to the soft tissue overlying the posterior part of the right thigh. The results of the study showed that the experimental group, which received application of Fluori-Methane spray and static passive stretch, did significantly (p less than .02) increase the range of passive hip flexion over that of the control group, which received only static passive stretch.
