Objectives : Post-stroke spasticity (PSS) significantly affects functional independence and quality of life. Frequent, guided rehabilitation is recommended, in combination with treatment, for effective management. Digital solutions, such as smartphone apps, offer alternative approaches when access to in-clinic rehabilitation is limited; however, to date there are no apps specifically for PSS. The iFlexo app is a goal-oriented, personalized approach designed to support patients with PSS in their rehabilitation journey. This study aimed to explore the usability of, and patient engagement with, iFlexo.

Design:

Adults with spasticity were asked to complete a tailored program in iFlexo, targeting their intended goal. The program was completed at home, in the participants’ own time and was structured to last for 12 weeks. It included sessions demonstrating physical exercises or educational aspects of PSS. User metrics were captured and a survey was conducted to assess satisfaction and compute a ‘Net Promotor Score’ (NPS), a standard outcome measuring how likely users are to recommend the app.

Results:

A total of 134 adults were included. Among them, 133 had PSS and 1 had cerebral palsy. Users completed 895 sessions in total, with an average daily usage time of 8.53 minutes. Survey responses (n=55) yielded an NPS of 43, indicating high user satisfaction and strong potential for recommendation.

Conclusion:

These findings suggest that iFlexo is a highly engaging and well-received digital tool for patients with PSS. Further development will focus on expanding content and enhancing personalization to further empower patients during their rehabilitation.
