The Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment for patients following acquired brain injury: Translation and reliability study.

OBJECTIVE

To develop the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment and to investigate its internal consistency, intra- and inter-rater reliability.

DESIGN

Prospective cohort study.

SETTING

Rehabilitation department.

SUBJECTS

A total of 34 patients with acquired brain injury.

MAIN MEASURE

The translation and cultural adaptation process was completed, and the testing procedures of the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment were standardized. Internal consistency was evaluated using Cronbach's alpha index; assessment of intra- and inter-rater reliability was carried out using weighted kappa coefficient.

RESULTS

The internal consistency of the tactile sensations and the proprioception items of the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment were generally acceptable to excellent with a range of Cronbach's alpha between 0.73 and 0.97. The intra-rater reliability of the tactile sensations and the proprioception items of the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment were generally good to excellent with a range of weighted kappa coefficients between 0.47 and 1.00. Likewise, the inter-rater reliabilities of these items were predominantly good to excellent with a range of weighted kappa coefficients between 0.42 and 0.92.

CONCLUSION

The Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment is a reliable screening tool to evaluate primary somatosensory impairments in patients with acquired brain injury. Further research is necessary to consolidate these results and establish the validity and responsiveness of the Italian version of the Erasmus MC modifications to the Nottingham Sensory Assessment.
