“…Such capability is vital for stroke patients with limited active movement. Prior studies have used sEMG biofeedback in the context of gait training [18,19] and upper limb training with several advantages, including the mitigation of cocontraction pattern [20], enhanced functional recovery outcomes when compared with conventional therapy [21,22], and good usability from the end-users [23]. Our current focus is on wrist extension training, which is pivotal for both ADLs [24,25] and hand grasping actions [26,27].…”

Background: Effective stroke rehabilitation requires high-dose, repetitive-task training, especially during the early recovery phase. However, the usability of upper-limb rehabilitation technology in acute and sub-acute stroke survivors remains relatively unexplored. In this study, we introduce sub-acute stroke survivors to the “MyoGuide”, a mobile training platform that employs surface electromyography (sEMG)-guided neurofeedback training for post-stroke wrist extension. Notably, the study places a strong emphasis on evaluating the platform’s usability within clinical contexts. Methods: We report the results of seven sub-acute post-stroke participants. The MyoGuide mobile training platform provided participants with real-time feedback, gamification features, and user control. Participants underwent wrist extension training, which encompassed calibration, stability assessment, and dynamic tasks. The training was conducted in supervised 1:1 sessions, spanning ten days. All training records were recorded within the application, usability was assessed through System Usability Scale (SUS) and a questionnaire administered during the final session. Daily written reports were provided by the therapist throughout the study duration. Results: The usability analysis yielded positive results, with a median SUS score of 82.5. Across the training sessions, patients progressed as indicated by significant increases in both the Stability Assessment Scores and the Level of Difficulty (LoD) that could be achieved in the dynamic task. The rate of progression differed based on initial impairment levels of the patient. During the training sessions, therapists documented not only the day-to-day performance of participants but also the extent of support required, particularly for those with lower baseline motor function. In parallel, participants who had experienced stroke expressed a keen interest in continuing home-based training. However, they also acknowledged challenges related to independently using the Myo armband and software. Conclusions: This study introduces the MyoGuide training platform and demonstrates its usability in a clinical setting for stroke rehabilitation, with the assistance of a therapist. The findings support the potential of MyoGuide for wrist extension training in patients across a wide range of impairment levels. However, certain usability challenges, such as donning/doffing the armband and navigating the application, need to be addressed to enable independent MyoGuide training requiring only minimal supervision by a therapist.

Background Effective stroke rehabilitation requires high-dose, repetitive-task training, especially during the early recovery phase. However, the usability of upper-limb rehabilitation technology in acute and subacute stroke survivors remains relatively unexplored. In this study, we introduce subacute stroke survivors to MyoGuide, a mobile training platform that employs surface electromyography (sEMG)-guided neurofeedback training that specifically targets wrist extension. Notably, the study emphasizes evaluating the platform’s usability within clinical contexts. Methods Seven subacute post-stroke patients (1 female, mean age 53.7 years, mean time post-stroke 58.9 days, mean duration per training session 48.9 min) and three therapists (one for eligibility screening, two for conducting training) participated in the study. Participants underwent ten days of supervised one-on-one wrist extension training with MyoGuide, which encompassed calibration, stability assessment, and dynamic tasks. All training records including the Level of Difficulty (LoD) and Stability Assessment Scores were recorded within the application. Usability was assessed through the System Usability Scale (SUS) and participants’ willingness to continue home-based training was gauged through a self-developed survey post-training. Therapists also documented the daily performance of participants and the extent of support required. Results The usability analysis yielded positive results, with a median SUS score of 82.5. Compared to the first session, participants significantly improved their performance at the final session as indicated by both the Stability Assessment Scores (p = 0.010, mean = 229.43, CI = [25.74–433.11]) and the LoD (p < 0.001; mean: 45.43, CI: [25.56–65.29]). The rate of progression differed based on the initial impairment levels of the patient. After training, participants expressed a keen interest in continuing home-based training. However, they also acknowledged challenges related to independently using the Myo armband and software. Conclusions This study introduces the MyoGuide training platform and demonstrates its usability in a clinical setting for stroke rehabilitation, with the assistance of a therapist. The findings support the potential of MyoGuide for wrist extension training in patients across a wide range of impairment levels. However, certain usability challenges, such as donning/doffing the armband and navigating the application, need to be addressed to enable independent MyoGuide training requiring only minimal supervision by a therapist.
