Item Analysis of the movements generated by a multi-field functional electrical stimulation device for upper extremity rehabilitation(2022-10) Martín-Odriozola, Aitor; Rodríguez-de-Pablo, Cristina; Caceres-Salegi, Ane; García-Calleja, Andrea; Marín-Ojea, Juan Ignacio; Hernández, Erik; Imatz-Ojanguren, Eukene; Keller, Thierry; Zabaleta-Rekondo, Haritz; Martín‐Odriozola, Aitor; Rodríguez‐de‐Pablo, Cristina; Caceres‐Salegi, Ane; García‐Calleja, Andrea; Marín‐Ojea, Juan Ignacio; Imatz‐Ojanguren, Eukene; Zabaleta‐Rekondo, Haritz; Medical Technologies; Tecnalia Research & InnovationBackground: The most common chronic sequela after stroke is the loss of arm function, and functional electrical stimulation (FES) applied to the forearm muscles is one of the options to treat it. Surface multi-field electrodes have emerged, showing a great potential to improve the selectivity of the stimulation, delay muscle fatigue, and provide easier donning and doffing. The muscular selectivity takes on special relevance in the rehabilitation of the upper extremity as hand dexterity requires a wide diversity of specific muscle actions. Methods: This pilot study analyses the movements generated in the wrist and fingers using a commercial multi-field technology-based FES device (Fesia Grasp). The study included five patients with hemiplegic subacute stroke, in which scanning of all cathodes of the electrode was carried out daily for 5 days, in two different forearm positions, with the resulting movements being labeled by experienced therapists. Results: The aim of this pilot study was to determine if there were differences between subjects and between forearm positions in terms of produced movements. Movements of the wrist (two movements) and the fingers (six movements) could be achieved in two different forearm positions. Conclusions: The multi-field electrode of Fesia Grasp enables to generate a wide range of movements of the hand in different positions. This fact could allow to produce more physiological movement patterns during the rehabilitation process with FES, which could have a beneficial effect on the recovery of patients with neurological diseases.Item ArmAssist Robotic System versus Matched Conventional Therapy for Poststroke Upper Limb Rehabilitation: A Randomized Clinical Trial: A randomized clinical trial(2017) Tomić, Tijana J. Dimkić; Savić, Andrej M.; Vidaković, Aleksandra S.; Rodić, Sindi Z.; Isaković, Milica S.; Rodríguez-de-Pablo, Cristina; Keller, Thierry; Konstantinović, Ljubica M.; Tecnalia Research & InnovationThe ArmAssist is a simple low-cost robotic system for upper limb motor training that combines known benefits of repetitive task-oriented training, greater intensity of practice, and less dependence on therapist assistance. The aim of this preliminary study was to compare the efficacy of ArmAssist (AA) robotic training against matched conventional arm training in subacute stroke subjects with moderate-to-severe upper limb impairment. Twenty-six subjects were enrolled within 3 months of stroke and randomly assigned to the AA group or Control group (n = 13 each). Both groups were trained 5 days per week for 3 weeks. The primary outcome measure was Fugl-Meyer Assessment-Upper Extremity (FMA-UE) motor score, and the secondary outcomes were Wolf Motor Function Test-Functional Ability Scale (WMFT-FAS) and Barthel index (BI). The AA group, in comparison to the Control group, showed significantly greater increases in FMA-UE score (18.0 +/- 9.4 versus 7.5 +/- 5.5, p = 0.002) and WMFT-FAS score (14.1 +/- 7.9 versus 6.7 +/- 7.8, p = 0.025) after 3 weeks of treatment, whereas the increase in BI was not significant (21.2 +/- 24.8 versus 13.1 +/- 10.7, p = 0.292). There were no adverse events. We conclude that arm training using the AA robotic device is safe and able to reduce motor deficits more effectively than matched conventional arm training in subacute phase of stroke.
