Design outcomes

Primary

MeasureTime frame
Level of dystonia / dyskinesia: the symptomatology is assessed separately according to episodic and permanent symptoms (in ADCY5-associated dystonia there are both entities). For episodic symptoms, we quantify frequency and temporal duration of symptoms. For the permanent symptoms, we use a parent assessment by a Likert scale 0-10 (no improvement to no symptoms). Additionally, analogous to the Rush Dyskinesia Rating Scale (RDRS as a clinically used instrument), we assess how much the symptomatology interferes with the activities of daily living (from not at all to activity not possible, e.g. walking freely).

Secondary

MeasureTime frame
Quality of sleep: Duration of falling asleep, duration of total sleep, restlessness, frequency of awakenings are assessed. Reaching motor milestones: walking distance and ability and endurance to stand freely, hand / arm dexterity in fine motor tasks is quantified.
