The PSS (Post Stroke Spasticity): Early Identification (ID) app is an innovative and easy-to-use smartphone application for healthcare professionals (HCPs) to learn about the importance of identifying and referring PSS early. HCPs will have access to ‘My Clinic’ where they will be assigned case studies which can be classified by dragging and dropping the avatar icon into one of the three referral pathways defined by the PSS Referral Tool to earn points. They will also have access to ‘Learn more about PSS’ where additional content on the early identification of PSS will be available. These insights will be reflected on ‘My Stats’ to encourage continuous engagement.
