The abdominal wall reflex test is a common test performed by the clinician, mainly by sliding a hard object or cotton swab over the upper, middle and lower abdomen while the patient is lying down, and the contraction of the abdominal wall muscles will be seen. If the contractions are bilaterally symmetrical and of uniform strength, this is a normal abdominal wall reflex. Abnormal abdominal wall reflexes have a special significance, especially in intracranial lesions, where one side of the abdominal wall reflex is often weakened or even absent due to damage to the central nervous system. If the abdominal wall reflex is hyperactive on one side, it is usually seen in hemiplegic chorea, while if it is hyperactive on both sides, it is mainly seen in Parkinson’s and sometimes in nervous or neurotic patients. If the abdominal wall is weak or absent on one side, it can also be seen in lesions of one cerebral hemisphere, mostly as a sign of sclerosis. Therefore, the abdominal wall reflex has a very important reference and value for clinicians as well as patients.
