This study assesses the effect of manipulative techniques of thrust and muscle-energy over the sacroiliac joint on plantar foot support, weight distribution in the lower limbs and balance in amateur runners with sacroiliac dysfunction. participants will be randomly assigned to one of 3 manipulations (i.e., intervention): thrust, muscle-energy or placebo.
The thrust manipulation applies a high velocity and intensity push in a specified direction to correct the position or movement of the sacroiliac joint. The muscle-energy technique consists of the therapist correcting the sacroiliac joint while the participant is applying active resistance. For the placebo manipulation, participants will receive a false manipulation over the affected joint, without producing movement at the sacroiliac joint.

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.

RECRUITINGChange in Weight Distribution
The baropodometry platform will be used to measure the distribution of weight (%) between legs.
Time frame: throughout study completion, an average of 1 month
Center of Gravity Displacement
The baropodometry platform will measure the distance traveled (mm in x- and y-axis)
Time frame: throughout study completion, an average of 1 month
Center of Pressure Displacement
The baropodometry platform will measure the distance traveled (mm in x- and y-axis)
Time frame: throughout study completion, an average of 1 month
Change in Plantar support
The baropodometry platform will measure the distribution of weight (%) across the foot (i.e., forefoot and rearfoot)
Time frame: throughout study completion, an average of 1 month
Foot Plantar Pressure
The baropodometry platform will measure the points of pressure across the foot with the aid of colorimetry (N/cm2)
Time frame: throughout study completion, an average of 1 month

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.
