Module II: Assessment of Sensory Motor Problems in Asperger’s Syndrome

Part I: Issues Pertaining to Assessment

Complexities Involved In Assessment of Individuals’ Sensory and Motor Problems

Let’s consider Susan’s case, described at the beginning of this module. Her behaviors warrant an assessment by a specialist who would be able to assess both sensory and motor difficulties related to her functional abilities. As indicated, this specialist is usually an occupational or physical therapist who has had specific training in the assessment of disorders of sensory integration. The therapist should also be well aware of the complexities involved in diagnosing people with Asperger’s Syndrome, as well as the complex issues when assessing a dysfunction of sensory integration. Each individual has his or her unique way of processing sensory information. Problems can occur on a consistent or inconsistent basis. Sensory problems, affecting emotions and behavior often appear more inconsistently. Motor problems often appear on a more consistent basis. Observed patterns might range from obvious to extremely subtle. External variables in the environment, such as noise and bright lights, provide a myriad of sensory experiences that can effect an individual’s response to that sensory input. Internal variables, such as being fatigued, or lacking inner awareness of how the body moves, can also have an effect on how a person develops skilled movement. Therefore, careful analysis, using both formal and informal measures, should be used for making a diagnosis of dysfunction of sensory integration. Trained professionals in the field of sensory integration should be well aware of these complexities.

Evaluators should also be aware that even with the present clinical tools of assessment, specialists could only hypothesize about what might be causing the behaviors that are seen. “Although neuroscientists are learning more and more about sensory processing and behavior, we are not yet able to determine definitive cause-effect relationships. Current best practice in assessment techniques reflects this growing knowledge in the neurosciences and its application to sensory processing in everyday life.” (p. 46)⁷
