Our study examined hip internal, external, abduction, and extension strength, as well as hip internal and external ROM both before and immediately after manual intervention. Our goal was to determine if manipulation and /or mobilization would increase strength and ROM greater than that of the control group. Sixty-one college aged students participated and were randomly assigned to one of three groups (control, mobilization, and manipulation groups).There was no significant difference within the control, mobilization, and manipulation groups when testing external rotation strength or in pre and post test measurements between the three testing groups in any of the dependent variables.
