Did you know that sensory hypersensitivity is prevalent after acquired brain injury?
Indeed, acquired brain injury patients frequently report an increased sensitivity to sensory stimuli following their brain injury compared to their pre-injury state (i.e., post-injury sensory hypersensitivity). Since post-injury sensory hypersensitivity can negatively impact quality of life, it is crucial to have appropriate assessment and treatment methods. However, adequate assessment and treatment is hindered by a lack of appropriate diagnostic tools as well as limited knowledge about the underlying mechanisms of self-reported post-injury sensory hypersensitivity.
Patient-friendly assessment of sensory sensitivity after brain injury
To address these issues, we developed the Multi-Modal Evaluation of Sensory Sensitivity (MESSY), a patient-friendly questionnaire that assesses sensory sensitivity across multiple sensory modalities (Thielen, Huenges Wajer et al., 2023, see below). The MESSY has adequate psychometric properties in neurotypical adults and is sensitive to sensory hypersensitivity in stroke, traumatic brain injury, and brain tumour patients. There are two versions of the MESSY: one version can be used in adults with a brain injury who are hospitalized in a hospital or rehabilitation injury and another version that can be used in non-hospitalized adults.
Interested in using the MESSY for research or clinical practice?
The Dutch version of the MESSY for non-hospitalized adults is freely available here.

Underlying behavioural and neural mechanisms of post-injury sensory sensitivity
After contributing to the improvement of the assessment of self-reported post-injury sensory sensitivity, we were able to start examining its underlying behavioural and neural mechanisms. In subsequent studies we explored the relationship between subjective visual sensitivity on the one hand and selective attention, sensory thresholds, and sensory processing speed on the other hand in subacute stroke patients (Thielen et al., submitted).
In addition, to explore the neural basis of post-injury sensory hypersensitivity we conducted a systematic literature review (Thielen, Tuts et al., 2023), a multiple case study (Thielen, Tuts et al., 2023), and a lesion-symptom mapping study (Thielen et al., 2025).
By contributing to scientific advancement and providing a patient-friendly diagnostic tool, we hope to improve patient care and in turn the quality of life of acquired brain injury patients with post-injury sensory hypersensitivity.
