Effects of Prism Adaptation and Transcranial Direct Current Stimulation on Unilateral Neglect in Stroke Patients : RCT

Gaurang Baxi, Tushar Palekar, sanjivani Kamble
Purpose:

In evaluating the most efficacious therapies for alleviating unilateral neglect symptoms, Prism Adaptation (PA) and Transcranial Direct Current Stimulation (tDCS) emerge as the two most effective bottom-up rehabilitation methods. These techniques operate on distinct explanatory mechanisms; however, to our knowledge, they have not been directly compared when applied across multiple sessions. An experimental investigation is necessary to determine if one of these two rehabilitation strategies is more helpful than the other in alleviating unilateral neglect symptoms in stroke individual.

Methods:

The research project included eligible people with unilateral neglect symptoms after a cerebrovascular accident. Group A received prism adaptation and conventional physiotherapy, while group B received transcranial direct current stimulation and conventional physiotherapy. Each group received the same before and after tests, including the Catherine Bergego scale (CBS) to assess general function and the Star cancellation test (SCT) to assess neglect.

Results:

After 2 weeks of treatment, both the A and B Groups improved in all outcome measures, including SCT and CBS scores in within-group analysis (P>0.0001). At the "2 Weeks" interval, the A Group had a significant statistical difference and a higher mean difference on all outcome measures than the B Group.

Conclusion(s):

Prism Adaptation therapy showed  improvement in unilateral neglect than tDCS, as reflected in CBS and SCT scores.

Implications:

Prism Adaptation therapy may offer a more effective approach than tDCS for treating unilateral neglect, supporting its use in stroke rehabilitation.
