Objective: To clarify the level of awareness of and support for post-stroke fatigue among medical professionals working in recovery phase rehabilitation wards. Methods: We conducted a questionnaire survey targeting all medical professionals (physicians, nurses, physical therapists, occupational therapists, and speech therapists) working in recovery phase rehabilitation wards of three facilities to evaluate their awareness of post-stroke fatigue and the support they were offering to address this. Quantitative data were subjected to statistical analysis and free description data were subjected to content analysis. Results: Of the 130 participants, we obtained responses from 94 (collection rate, 72.3%; valid response rate, 100%). Those who felt that post-stroke patients are always tired or tire easily comprised 63.8%. Those who acknowledged the importance of post-stroke fatigue as a problem and that it is an issue that must be addressed comprised 70.2% and 73.4%, respectively. Issues emerging due to post-stroke fatigue were extracted as follows: "Difficulty continuing with rehabilitation," "Decreased drive," "Difficulty with emotional control/ depression," "Fewer interactions with others," and "Loss of goals." Support for post-stroke fatigue was offered by 57.4% of medical professionals, most commonly as individual support such as "Ensure rest." The effects of support were described as "Cannot say either way" (44.4%), with 3.7% noting that they were not very effective. Awareness and support rates among therapists were significantly higher than those among nurses. Conclusions: Post-stroke fatigue is acknowledged by medical professionals as a critical issue that negatively influences the patient's physical, emotional, and daily living functions. Unfortunately, effective support is not currently being offered, demonstrating the need for the development of appropriate interventions.
