In a recent article, researchers discuss the importance of timely treatment for stroke patients in order to minimize brain damage. They highlight the efforts being made to educate the public about detecting stroke symptoms, such as the face, arms, and speech test (FAST). However, in this position paper, the authors propose a new method for assessing arm weakness using integrated video tracking from an iPhone. They perform various tests to evaluate the tracking quality and identify potential areas of concern. The researchers conducted the arm weakness test on four stroke patients and compared the results with the clinician’s report. While the system has some limitations, it successfully detected arm weakness as a symptom of stroke. The authors believe that introducing a portable body tracking system in clinical tests could offer benefits in terms of objectivity, repeatability, and the ability to compare groups of patients.
