The Quantitative Study Of Hyperactivity/impulsivity Symptom In Attention-deficit/hyperactivity Disorder

Objectives: We aimed to quantify the ability of motion sensor data, takenfrom3-axis acceleration sensor, to distinguish the combined orhyperactive-impulsive subtypes of attention-deficit hyperactivity disorder(ADHD). Furthermore we aimed to find an objective auxiliary diagnosis waywhich will useful for outpatient with combined or hyperactive-impulsivesubtypes of ADHD.Method: Cross-section research and Receiver operating characteristicanalysis were used on3-axis acceleration sensor data collected during a limitedscene, which cost about20minutes, in a sample of70ADHD combined-type,diagnosed by experienced clinical doctors, and70control siblings, matched byage, gender and weight.Results: Two measures of3-axis acceleration sensor data-mean counts andenergy expenditure-yielded a P＜0.05, indicating an ability to distinguishbetween cases and controls. The diagnostic efficiency is excellent of thediagnostic way combined with3-axis acceleration sensor and integrated visualand auditory continuous performance test (IVA-CPT), yield an area under thecurve is0.910, and the sensitivity up to90%, and the specificity up to80%. Conclusions: a. The research about to quantify the hyperactive/impulsivesymptom with ADHD must be done in a limited scene. b. The measures of3-axis acceleration can quantify the hyperactive/impulsive symptom of ADHD.c. The diagnostic efficiency is excellent of the diagnostic way combined with3-axis acceleration sensor and IVA-CPT. Maybe it is worth to use in clinicaldiagnostic test when the results are validated in screening tests. d. It is not clearabout the correlation between age and hyperactive/impulsive symptom in thisstudy. Further studies need to be done to make sure the correlation.
