Paratonia is one of the associated movement disorders characteristic of dementia. The aim of this study was to develop an assessment tool (the Paratonia Assessment Instrument, PAI), based on the new consensus definition of paratonia. An additional aim was to investigate the reliability and validity of the PAI. ⋯ The PAI is a reliable and valid assessment tool for diagnosing paratonia in elderly people with dementia that can be applied easily in daily practice.
