Differentiation between process and reactive schizophrenia based on vestibular reactivity, grasp strength, and posture.

The sensory-integrative treatment approach for the adult schizophrenic was indirectly examined by focusing on the differences between process and reactive subtypes of schizophrenia. Differences between the process and reactive schizophrenic were evaluated on the basis of three variables; grasp strength, posture, and vestibular reactivity. Results of the study indicated a significant difference between the process subtype schizophrenic subjects and normal subjects on all three variables, and a significant difference in vestibular reactivity between the process and reactive schizophrenic groups. Vestibular reactivity appears to be a variable by which to distinguish between reactive and process schizophrenic patients.
