Study characteristics
Methods	3‐group parallel RCT Setting: hospital, South Korea
Participants	Inclusion: individual with diagnosis of unilateral neglect from a medical doctor and number of lines neglected in Albert test > 70%; individual without brain lesions other than stroke; individual with less than 3 months since stroke; individual with Korean version of Mini‐Mental Status Examination (K‐MMSE) score ≥ 20, who can follow directions and does not have hearing or vision impairment Age: mean, SD 62.90 ± 8.64, Group A 67.70 ± 9.76, Group B 66.00 ± 12.09, Group C Sex: 17 women, 13 men Hemisphere damaged: not specified Time since stroke: 1 to 3 months
Interventions	This study has 3 intervention groups PA plus FES group (Group A) PA group (Group B) FES group (Group C) ‐ Group A received 30 minutes of conventional occupational therapy, followed by FES application on upper limb on the affected side and PA treatment for 20 minutes, for a total of 50 minutes. Conventional occupational therapy was conducted for 30 minutes and included joint movement, task‐oriented training, and daily life activity training. Joint movement was conducted and included passive joint movement, active adjuvant joint movement, and active joint movement. Task‐oriented training considered functional level of patients and used tools to sequentially conduct activities such as cup‐stacking and skateboarding. Daily life activity training included using the restroom, eating a meal, performing personal hygiene activities, wearing and taking off clothes, and transferring to chair or bed. Participants wore prism glasses that deflect the axis of vision to the right by 15 degrees, with the proximal surface shaped like a triangle facing the left. For FES, a product from Microstim was used. One channel was used and was set to apply, in shifts, 10 seconds of rest and 10 seconds of stimulation. It was attached below the elbow on the affected side. Although an intensity of 20 Hz is normally recommended, the threshold for electrical stimulation is different for each participant. Therefore, it was set to contract muscles enough to produce sufficient finger and wrist movements ‐ Group B received 30 minutes of conventional occupational therapy, followed by PA on the upper limb on the affected side for 20 minutes, for a total of 50 minutes ‐ Group C received 30 minutes of conventional occupational therapy, followed by FES application for 20 minutes, for a total of 50 minutes
Outcomes	K‐MMSE Albert test MVPT CBS All taken immediately post intervention with no longer‐term follow‐up
