Description:diaDoc is an examination tool for medical professionals. This app uses the built-in gyro sensor of an Apple iPhone or iPod to record rapid, alternating and rotary movements of the hand and forearm.Parameters to describe the recorded movement cycles (frequency, amplitude, maximum angular velocity) are calculated and displayed together with a detailed graphical analysis of the motion sequence.A printable report is created, it is stored in the app's archive or exported to Dropbox or other apps or sent by email.Background:In medical terminology rapid alternation of supination (palm up) and pronation (palm down) is known as “diadochokinesis”. Different movement disorders can cause disturbance of diadochokinesis, also known as “dysdiadochokinesis”.Clinical examination of diadochokinesis is rather inexact. Interrater reliability is weak. Even the same examiner will have difficulties to detect less pronounced changes over time.Frequency and amplitude of a movement can roughly be assessed by vision. However, precisely defined values and only measurable parameters like maximum angular velocity may also be of diagnostic importance.Moreover, a comparative analysis of the recorded curves may offer additional information on pathological movement patterns.Meanwhile, Apple handheld devices are widely available. They can easily be used as a pocket tool to complement clinical examination.The objective of diaDoc is to provide a “mobile diadochokinesiography” for rapid information and documentation in clinical practice.diaDoc has been tested by the developer (a clinical neurologist himself) in an outpatient setting and it seems to show sufficient test-retest reliability.To be used as an acceptable diagnostic tool, the app has, however, to be formally evaluated for reliability in controlled studies of normal subjects and patients with biostatistic assistance.Any such study performed by professional users will be supported.Anyone who can contribute to the improvement of diaDoc is expressly invited to send her/his comments or suggestions to:info@4neuro.com
