“…The inverse ILC update with step size β = 1 is employed due to its rapid convergence and prior tremor implementation [30], hence producing L ĉ = P −1 p . A 10 th order zero-phase low-pass filter with cut-off frequency 5Hz is established and lifted using (5) to produce a robustness filter Q ĉ, in order to satisfy the design protocol in Algorithm 1.…”

Functional electrical stimulation (FES) is an effective upper limb stroke rehabilitation technology that helps patients recover lost movement by assisting functional task training. Unfortunately, current FES controllers cannot satisfy the competing demands of high accuracy, robustness to modelling error and limited set-up/identification time needed for clinical or home deployment. To address this, an estimationbased multiple model switched iterative learning control framework is proposed, combining the most successful adaptive learning features of existing FES controllers. A practical design procedure that guarantees robust performance is developed, and efficacy is established across realistic testing scenarios.

“…The strategy is relatively simple but low joint frequency may affect patients' voluntary movement and the patients might have muscle fatigue quickly as they need to generate more muscle force to perform voluntary activities. Musculoskeletal models have been applied to evaluate the feasibility of FES based on the co-contraction strategy for tremor suppression (Wang et al, 2015;Zhang et al, 2019). The joint can be modeled as a 2nd order linear time variant system in which the FES effect was described as a variable stiffness and viscosity (Alvaro Gallego et al, 2013a,b).…”

Parkinsonian tremor is one of the most common motor disorders in patients with Parkinson's disease (PD). Compared to oral medications and brain surgery, electrical stimulation approaches have emerged as effective and non-invasive methods for tremor reduction. The pathophysiology, detection and interventions of tremors have been introduced, however, a systematic review of peripherical electrical stimulation approaches, methodologies, experimental design and clinical outcomes for PD tremor suppression is still missing. Therefore, in this paper, we summarized recent studies on electrical stimulation for tremor suppression in PD patients and discussed stimulation protocols and effectiveness of different types of electrical stimulation approaches in detail. Twenty out of 528 papers published from 2010 to 2021 July were reviewed. The results show that electrical stimulation is an efficient intervention for tremor suppression. The methods fall into three main categories according to the mechanisms: namely functional electrical stimulation (FES), sensory electrical stimulation (SES) and transcutaneous electrical nerve stimulation (TENS). The outcomes of tremor suppression were varied due to various stimulation approaches, electrode locations and stimulation parameters. The FES method performed the best in tremor attenuation where the efficiency depends mainly by the control strategy and accuracy of tremor detection. However, the mechanism underlying tremor suppression with SES and TENS, is not well-known. Current electrical stimulation approaches may only work for a number of patients. The potential mechanism of tremor suppression still needs to be further explored.

A doença de Parkinson é a segunda doença neurodegenerativa mais comum do mundo, sendo o tremor um dos seus principais sintomas. Os tratamentos existentes para o tremor possuem diversas restrições e efeitos colaterais que acabam limitando seu uso. Dessa forma surge a ideia de tratamentos alternativos, usando a engenharia, que sejam menos invasivos e sem efeitos colaterais. O escopo deste trabalho será apresentar e discutir as principais soluções envolvendo a engenharia para a redução de tremores patológicos que foram encontradas nos últimos anos. Para fins de seguir uma metodologia de pesquisa, foram utilizadas palavras-chaves para realizar buscas em alguns dos principais bancos de dados científicos, e com alguns filtros aplicados foi possível identificar 26 artigos que tratam sobre o tema que desejamos estudar. Como resultados foi possível perceber um aumento considerável do estudo sobre o tema nos últimos anos e observar a existência de 4 categorias de tratamentos alternativos: estimulação elétrica funcional (FES), atuadores mecânicos, sistemas amortecidos e materiais inteligentes. Após a pesquisa, concluiu-se que as soluções usando FES e atuadores mecânicos foram as mais estudadas e as que se encontram em fases mais avançadas de teste, já havendo produtos no mercado que utilizam a FES como tratamento para tremores patológicos.
