Abstract

Objective

To validate a subgroup classification tool designed to support clinical decision-making in vestibular physiotherapy.

Methods

A structured instrument was developed based on the main vestibular disorders commonly treated by physiotherapists. The tool was applied by professionals to simulated clinical cases. Content validation was performed by expert judges using the Delphi technique. The Content Validity Index was calculated for each item.

Results

The tool obtained a Content Validity Index of 0.78 or more across all domains in the first round and reached 100 per cent agreement among experts in the second round, confirming its content validity. The tool demonstrated clarity, coherence and clinical relevance for decision-making in vestibular rehabilitation.

Conclusion

The validated tool presents evidence of content validity and clinical applicability, offering support for physiotherapists in the classification and management of vestibular disorders.
