The database is a collection of postural data acquired from 10 patients affected by the rare Stargardt’s syndrome, all having the ABCA4 gene mutation, and from 10 control healthy subjects. Specifically, the database includes a file (.xlxs) called SubjectsData and 20 datasets (MATLAB structures) containing postural signals. Each subject performed a total of 15 postural tests, 5 postural tests for 3 different conditions (‘C’: eyes-closed; ‘O’: eyes-open, still target fixation; ‘M’: eyes-open, moving target tracking). For each postural test, 11 postural derived signals (the anterior-posterior force, the medio-lateral force, the weight force, the three torques on the three reference axis , the two torques on the x and y axis on the platform surface, the two coordinates of the center of pressure, and the free torque on the z axis) were computed from 8 raw signals, acquired at the Ophthalmic Hospital of Turin, Italy, through an 8-channel Kistler 9286A force platform connected to a Step32 system. Thus, a total of 285 postural signals (120 raw and 165 derived) are available for each subject. The database may be useful to: (1) investigate postural adaptations of patients affected by Stargardt’s syndrome; (2) support definition of rehabilitative procedures to reduce postural instability of patients affected by Stargardt’s syndrome; and (3) support investigation on visual control of balance in the general population.
