What are good rehab exercises to do after an oblique strain?

Heal first....rehab: There are different degrees of strain; assuming a mild strain. Phase i iinvolves icing, compression to reduce swelliing and minimize the zone of injury. Phase 2 is to restore pain free range of motion through simple stretches and proper breathing. Phase 3 strengthening, can start with isometrics, simple crunches to get the muscle contracting then add the oblique movment. Keep it pain free.

Stretch: Most muscle strains are relieved with resting the part. Massage myofascial releases and modalities such as warmth hydrotherapy therapeutic ultrasound or tetanizing galvanic current help tremendously. Avoid repetitive microtraumatization and begin and end exercise with stretching sessions.
