Potentiation of the Effects of Prismatic Adaptation by Transcranial Direct Current Stimulation (tDCS) : Evaluation of Functional Interest in Negligence Rehabilitation

Not Applicable
Completed
Conditions
Neurologic Neglect Syndrome
Interventions
Device: transcranial direct current stimulation (tDCS)
Registration Number
NCT02213640
Lead Sponsor
Hospices Civils de Lyon
Brief Summary

Following stroke, over 50% of patients keep severe neurological deficiency whose unilateral neglect, mostly following a right hemispheric lesion. The prismatic adaptation involves to pointing movements toward visual targets wearing prismatic glasses. These prismatic glasses induce a shift to the right visual field for improving symptoms in short term.

Transcranial direct stimulation (tDCS) has been evaluated for different types of deficiency resulting from stroke with encouraging results. The hypothesis of the study is to evaluate the usefulness of brain stimulation as an adjunctive intervention to optimize and increase the rehabilitation of unilateral neglect to long-term.

Thus, the main objective is to evaluate the effectiveness of standard treatment with prismatic adaptation with anodal tDCS or sham tDCS.

Behavioural Inattention Test (BIT)Change in BIT score between the baseline sessions average and score measured at week 11

assessed at two baseline sessions before intervention (inclusion and week 3), and after the therapeutic intervention week (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20) following the inclusion.

Secondary Outcome Measures
NameTimeMethod
Negligence Battery Test (BTN)before intervention (week 1 and week 3), and then again following the intervention (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20)

Change in BTN scores between baseline measures before the therapeutic intervention week and scores obtained during each follow-up sessions

Jamarbaseline session before intervention (week 1 and week 3), and then again following the intervention (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20)

Change in Jamar scores between baseline measures before the therapeutic intervention week and scores obtained during each follow-up sessions

Functional independence scale (MIF)before intervention (week 1 and week 3), and then again following the intervention (week 5), 2 weeks (week 7), 6 weeks (week 11) and 15 weeks (week 20)

Change in MIF scores between baseline measures before the therapeutic intervention week and scores obtained during each follow-up sessions
