Can you provide me with information about sacroiliac joint (SI Joint) injury and exercises which may help this injury?
The Research Corner can only address questions that seek to educate, not diagnose and/or prescribe a client problem. A physical therapist is best equipped to prescribe the corrective exercise techniques that will address your client's SI joint injury.
SI joint dysfunction is a GENERAL term therefore, it would be difficult to address specifically. A physical therapist may suggest a low level core stabilization/ balance program to assist in regaining stability in your SI joint.
Personal Training on the Net has many articles that address Core Stabilization and Balance. Use the Keyword search functions to locate the articles that will assist you in this area.
