Objectives: The aim of this study was to investigate the immediate effect of sensory electrical stimulation (SES) and task-related trunk training (TRTT) interventions on sitting postural control in stroke survivors.Methods: Acute to subacute stroke survivors were screened and recruited for this study. Patients were randomly assigned to the SES group, receiving TRTT combined with simultaneous SES of the neck and lumbar muscles, or to the sham group, receiving TRTT combined with sham stimulation. The primary outcome of the sitting task assessment was the joint angles of the neck and trunk. The outcome was measured at three time points (baseline; online effect: 10 min after the intervention started while the intervention continued; and after-effect: immediately after the intervention).Results: In total, 26 patients were divided into the SES (n=13) and sham (n=13) groups. The SES group showed a significant increase in the trunk joint angle for the online effect (P=0.03) and the after-effect (P=0.01) when compared with those measured at baseline.Conclusions: TRTT combined with simultaneous SES of the neck and lumbar muscles can immediately change the trunk angle during a sitting balancing task.

Objectives: This study aimed to clarify the effect of an intervention using a head-mounted display with a web camera set at a modified pitch angle on spatial awareness, sit-to-stand movement, and standing balance in patients with left and right hemisphere damage.Methods: The participants were 12 patients with right hemisphere damage and 12 patients with left hemisphere damage. The line bisection test, a sit-to-stand movement, and balance assessment were performed before and after the intervention. The intervention task involved pointing at targets 48 times in an upward bias condition.Results: Significant upward deviation on the line bisection test was noted in patients with right hemisphere damage. The load on the forefoot during the sit-to-stand movement was significantly increased. The range of anterior–posterior sway during forward movement in the balance assessment was reduced.Conclusions: An adaptation task performed in an upward bias condition may produce an immediate effect on upward localization, sit-to-stand movement, and balance performance in patients with right hemisphere stroke.

Background: Functional electrical stimulation (FES) improves unilateral spatial neglect (USN). However, only few studies have reported on the relationship between FES and cognitive function. Therefore, this study aimed to investigate the effects of FES on attentional function in healthy participants using the Posner task, which is generally used to assess patients with USN.Methods: In this interventional study, we conducted experiments on healthy participants to obtain fundamental knowledge before investigating effective ways of adapting FES to patients with USN as our final purpose. A total of 28 right-handed healthy young participants were assigned to the online-effect group or after-effect group and underwent FES simultaneously with or immediately before the Posner task, respectively. FES was applied to the extensor muscles of the left forearm to induce involuntary movement.Results: A significant difference was observed in the effects of FES in the Posner task between the online-effect group or after-effect group in the left-valid conditions (online-effect, 26.7 ms delay; after-effect, -0.4 ms [reduction]; p = 0.01). No interaction was noted between the groups and the type of target of the Posner task presentation condition. The effects of FES differed between the online- and after-effect condition groups.Conclusion: Performing the attention task after FES may enhance attention compared with performing the task with FES simultaneously.
