Abstract
[Purpose] The purpose of this study was to examine the effect of kinesthetic illusion induced by visual stimulation (KiNvis) for dorsiflexion dysfunction caused by Guillain–Barre syndrome. [Subjects and Methods] This study had an ABA single-case design and was conducted in phases of 3 days each. In phase A, the patient underwent conventional physical therapy for 3 days. In phase B, the patient underwent KiNvis before physical therapy, which was the same physical therapy program as in phase A. The patient was evaluated using a visual analog scale (VAS), self-portrait drawing, ankle dorsiflexion automatic movement angle (ADAMA), and the 10-meter walk test. [Results] In phase B, the VAS for kinesthetic illusion averaged 55 ± 5 mm, and self-portrait drawing, assessed by the patient completing a drawing of the affected ankle joint, changed to a more detailed picture following phase B. Both ADAMA and gait speed improved. [Conclusion] The addition of KiNvis to a conventional rehabilitation program enhanced improvements in dorsiflexion function.
