Acute Event

Recovery of therapeutic or functional ambulatory capacity in patients with rotator cuff injury is a primary goal of rehabilitation. Wearable powered exoskeletons allow patients to perform repetitive practice with large movements to maximize recovery, even immediately after the acute event. The aim of this paper is to describe the usability, acceptability and acceptance of a hybrid exoskeleton for upper-limb passive rehabilitation using the System Usability Scale (SUS) questionnaire. This equipment, called ExoFlex, is defined as a hybrid exoskeleton since it is made up of rigid and soft components. The exoskeleton mechanical description is presented along with its control system and the way motion is structured in rehabilitation sessions. Seven patients (six women and one man) have participated in the evaluation of this equipment, which are in the range of 50 to 79 years old. Preliminary evidence of the acceptance and usability by both patients and clinicians are very promising, obtaining an average score of 80.71 in the SUS test, as well as good results in a questionnaire that evaluates the clinicians’ perceived usability of ExoFlex.

In order to make most patients recover most of their limb functions after rehabilitation training, virtual reality technology is an emerging human-computer interaction technology, which uses the computer and the corresponding application software to build the virtual reality environment. Completing the training tasks in the virtual environment attracts the patients to conduct repeated training in the game and task-based training mode and gradually realizes the rehabilitation training goals. For the rehabilitation population with certain exercise ability, the kinematics of human upper limbs is mainly analyzed, and the virtual reality system based on HTC VIVE is developed. The feasibility and work efficiency of the upper limb rehabilitation training system were verified by experiments. Adult volunteers who are healthy and need rehabilitation training to participate in the experiment were recruited, and experimental data were recorded. The virtual reality upper limb rehabilitation system was a questionnaire. By extracting the motion data, the system application effect is analyzed and evaluated by the simulation diagram. Follow-up results of rehabilitation training showed that the average score of healthy subjects was more than 4 points and 3.8 points per question. Therefore, it is feasible to perform upper limb rehabilitation training using the HTC VIVE virtual reality rehabilitation system.

Abstract Background: Neuroscience and neurotechnology are changing stroke rehabilitation. Robotic devices as well as telerehabilitation have become of great interest and are increasingly being used to train the upper extremities after stroke. Its use in home settings allows to extend institutional rehabilitation by increasing and prolonging therapy. The aim of this study is to assess the usability of MERLIN robotic system based on serious games for the upper limb rehabilitation in stroke patients in a home environment.Methods: 12 participants with a stroke in three different stages of evolution (subacute, chronic of short evolution and long-term chronic) with impaired arm/hand function were recruited to use the MERLIN system for 3 weeks: one week of training at the Maimonides Biomedical Research Institute of Cordoba (IMIBIC), and 2 weeks at patients’ home. Evaluation of usability involved System Usability Scale (SUS), Adapted Intrinsic Motivation Inventory (IMI), Quebec User Evaluation of Satisfaction with assistive Technology (QUEST), and ArmAssist Usability Assessment Questionnaire which were evaluated post-intervention. Clinical outcomes on upper extremity motor function were assessed pre- and post-intervention.Results: Finally, 9 patients participated in the study, 3 drop-off due to the COVID-19. The usability assessment reported a high level of satisfaction: mean SUS score was 71.94 % (SD=16.38), mean QUEST scale was 3.81 (SD=0.38), and mean IMI score was 6.12 (SD=1.36). The results of the ArmAssist Questionnaire was an average of 6 out of 7, which indicates that MERLIN is easy to learn, easy to use and intuitive. Regarding clinical assessment, Fugl-Meyer scores showed moderated improvements from pre- to post-intervention in the total score of motor function (p = 0.002). There were no significative changes in Modified Ashworth scale outcomes (p = 0.169) Conclusions: This usability study indicates that home-based rehabilitation for upper limb with MERLIN system is safe, useful, feasible and motivating. The telerehabilitation suppose an important step towards an intensive rehabilitation to be bring to home.Trial registration: ClinicalTrials.gov, NCT04405609.
