The calculator in question is the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) diagnostic criteria for catatonia. This scoring system is used in the field of psychiatry and applies to patients who are suspected of having catatonia, a syndrome characterized by a variety of motor abnormalities and behavioral changes. 

The DSM-5 diagnostic criteria for catatonia is used to identify and diagnose catatonia in patients, which can occur in the context of several disorders such as schizophrenia, bipolar disorder, major depressive disorder, or can be due to a general medical condition or as an adverse reaction to substances. 

The clinical utility of this calculator is to provide a standardized method for diagnosing catatonia, which can guide appropriate treatment strategies. It includes criteria such as catalepsy, waxy flexibility, stupor, agitation, mutism, negativism, posturing, mannerism, stereotypy, grimacing, echolalia, and echopraxia. 

There are no specific exclusion criteria for its use, but it should be noted that the presence of catatonia should prompt clinicians to search for an underlying cause, as catatonia is a syndrome and not a disease in itself. It is also important to differentiate cat
