Abstract

In recent years, significant technological advancements have been achieved in the evaluation of the vestibular system, and particularly the Video Head Impulse Test (vHIT) has become widely used in clinical practice. The Head Impulse Paradigm (HIMP) and the Suppression Head Impulse Paradigm (SHIMP), which are used within the scope of vHIT, are two important complementary methods for the assessment of the vestibulo-ocular reflex (VOR). While HIMP provides high sensitivity and specificity in detecting vestibular loss, SHIMP contributes to the evaluation of residual vestibular function and saccadic adaptation. In the SHIMP paradigm, the patient is instructed to follow a target moving together with the head, allowing the analysis of anti-compensatory saccades. In particular, reducing the effect of covert saccades on VOR gain measurements is considered one of the major advantages of SHIMP. This review discusses in detail the history of SHIMP, its working principles, and its relationship with HIMP and vHIT; additionally, information regarding the Functional Head Impulse Test (fHIT) is presented. The development process and clinical use of SHIMP in Türkiye are also evaluated. Literature findings indicate that SHIMP provides important contributions in the identification of vestibular loss, the evaluation of vestibular compensation, and the monitoring of rehabilitation processes. Consequently, the combined use of SHIMP, HIMP, vHIT, and fHIT offers a comprehensive approach for the diagnosis, follow-up, and rehabilitation of vestibular disorders.

Özet

Vestibüler sistemin değerlendirilmesinde son yıllarda önemli teknolojik gelişmeler yaşanmış ve özellikle Video Baş İmpuls Testi (video Head Impulse Test; vHIT) klinik uygulamalarda yaygın olarak kullanılmaya başlanmıştır. vHIT kapsamında kullanılan Head Impulse Paradigm (HIMP) ve Suppression Head Impulse Paradigm (SHIMP), vestibülo-oküler refleksin (VOR) değerlendirilmesinde birbirini tamamlayan iki önemli yöntemdir. HIMP, vestibüler kaybın belirlenmesinde yüksek duyarlılık ve özgüllük sağlarken, SHIMP rezidüel vestibüler fonksiyonun ve sakkadik adaptasyonun değerlendirilmesine katkı sunmaktadır. SHIMP paradigmasında hastanın baş ile birlikte hareket eden bir hedefi takip etmesi sağlanmakta ve bu yöntem sayesinde anti-kompansatuvar sakkadlar analiz edilmektedir. Özellikle covert sakkadların VOR kazanç ölçümlerine etkisini azaltması SHIMP’in önemli avantajlarından biri olarak kabul edilmektedir. Bu derlemede SHIMP’in, çalışma prensibi, HIMP ve vHIT ile ilişkisi ayrıntılı olarak ele alınmış; ayrıca Fonksiyonel Baş İmpuls Testi (Functional Head Impulse Test; fHIT) hakkında bilgi verilmiştir. Türkiye’de SHIMP’in gelişim süreci ve klinik kullanımı da değerlendirilmiştir. Literatür verileri, SHIMP’in vestibüler kayıpların belirlenmesi, vestibüler kompanzasyonun değerlendirilmesi ve rehabilitasyon süreçlerinin izlenmesinde önemli katkılar sağladığını göstermektedir. Sonuç olarak SHIMP, HIMP, vHIT ve fHIT’in birlikte kullanımı vestibüler hastalıkların tanı, takip ve rehabilitasyonunda kapsamlı bir değerlendirme yaklaşımı sunmaktadır.
