Objective : This study aim is to identify whether smooth pursuit eye movement(SPEM) using portable
device can alleviate chronic hemispatial neglect.
Methods : We applied smooth pursuit eye movement to one chronic hemispatial neglect patient.
Experimental duration was total 4weeks - 1week baseline, 2weeks SPEM intervention, 1week
2nd. baseline. The intervention was 10 SPEM sessions (30min each, 1session daily, from Monday
to Friday) over a period of 2weeks. The neglect test carried out 5 times a week. The SPEM was
provided on the screen when patient sat in front of the screen(8.4 inch tablet pc, distance 40cm).
The SPEM video that the 24 yellow squares moving coherently from the right to the left side.
Patients were instructed to perform smooth pursuit eye movement without head and neck
movement.
Results : As a result of the SPEM for 2weeks, the degree of neglect tended to decrease compared
to baseline A. The degree of the LBT tended to increase the at the baseline A`. In contrast, the
SCT showed that tendency which the degree of the neglect maintained at the baseline A`.
Conclusion : We identified that SPEM using portable device is effective intervention method for
chronic hemispatial neglect.
