Osteopathic Thrust and Muscle-energy Manipulations on Sacroiliac Joint Dysfunction

The therapist simulates a false technique. The therapist applies movement in the sacroiliac joint without dysfunction, he applies movement since ninety degrees of pelvic flexion, and he wait sixty seconds. Whit this placebo technique the sacroiliac joint with the dysfunction is not altered.

The osteopathic manipulation type thrust is applied to solve the sacroiliac joint dysfunction. This technique applies a high velocity and intensity push in a specified direction to correct the dysfunction produced by a not correct position or movement of one joint.

The muscle-energy manipulation is applied to solve the sacroiliac joint dysfunction. This technique applies a movement with an intermittent resistance in a specified direction to correct the position or movement of one joint. The therapist applies the movement in the correct direction since he feels a limitation of movement. When he feels the limitation he requests to the participant pushing in the contrary direction without movement. After five or seven seconds the participant finishes the contraction and the therapist continues the correct movement since he feels once again the limitation, and he request to the participant contraction another five or seven seconds. The therapist request to the participant only three times, when he finish the three contraction and the therapy applies the last movement to correct direction the intervention finishes.
