Musculoskeletal and Obstetric Management (MOM): In addition to their standard obstetric visits, patients in this group will see the MOM team every one to two weeks depending on severity of symptoms. We have found through treating pregnancy-related pain that visits every one to two weeks is sufficient as the majority of the cases are mild to moderate presentations of non-inflammatory pain. A standard history will be taken and the patient will be assessed for musculoskeletal conditions to identify signs of serious illness, neurological deficit and/or orthopedic instability. If any of these conditions are evident, the patient will be immediately referred for specialist consultation. The patients in this MOM group will be treated with biobehavioral management, manual therapy and spinal stabilization exercise as described in detail below. The obstetric physician and chiropractic physician will have coordinated schedules at each clinic. For pain that is debilitating and worsening, consultation with orthopedic or neurological services will be considered.
