“…Another study 29 also demonstrated that during a manufacturing task in which volunteers had to move objects and place them into a box, there was a significant increase in the activation of the upper trapezius, anterior deltoid, and posterior deltoid. With an electromyographic analysis, Ferrigno et al 30 reported that the use of a static wrist orthotics during a typing and computer mouse handling task also influenced the higher recruitment of the upper trapezius muscle, in agreement with the findings of this study.…”

RESUMO As órteses são recursos terapêuticos indicados para proteger, corrigir deformidades ou auxiliar em certas funções; porém, seu uso pode acarretar compensações proximais no ombro. O objetivo deste estudo é avaliar a influência da órtese estática dorsal do punho, em 30° de extensão na biomecânica do ombro e cotovelo, em 25 voluntários assintomáticos durante uma tarefa funcional. Os dados da amplitude de movimento e ativação muscular foram adquiridos de forma sincronizada e simultânea durante parte do teste funcional Elui, que simula alimentação, dividida em alcance, deslocamento e liberação, de uma jarra, nas condições sem e com órtese. Para possibilitar a comparação entre os diferentes sujeitos e músculos, os dados foram analisados pela integral do sinal EMG de cada músculo e, para análise cinemática, foram construídos sistemas de coordenadas de marcadores pré-definidos. Os sinais captados foram filtrados e processados por um software personalizado, e utilizou-se o teste t para amostras pareadas - software SPSS, p<0,05. Notou-se um aumento significativo da ativação dos músculos deltoide anterior e peitoral maior na fase de alcance, e trapézio superior, deltoide anterior e posterior na fase de liberação com a órtese. A cinemática mostrou aumento significativo na amplitude de movimento na abdução do ombro, flexão do cotovelo e pronação do antebraço na fase de deslocamento, e dos movimentos extensão do ombro e flexão do cotovelo na fase de liberação. Nossos achados sugerem que o uso da órtese estática do punho durante a execução de uma tarefa pode acarretar compensações, com predomínio da ativação dos músculos mais proximais do membro superior.

“…Muscle selections were based on the actions of proximal and distal muscles during upper extremity movement ( Table 1). The upper portion of the Trapezius (Tp) muscle, the anterior (AD) and posterior (PD) portions of the Deltoid, the Pectoralis Major (PM) muscle, the Biceps Brachii (Bbr), and Triceps brachii (Tbr) were selected for their major roles in the stabilisation and movement of the shoulder and elbow joints during activities involving fine hand movements (Ferrigno et al, 2009;Naider-Steinhart & Katz-Leurer, 2007;Ricci, Santiago, Zampar, Pinola, & Fonseca, 2015;Yoo, Jung, Jeon, & Lee, 2010).…”

“…The study of muscle activation through surface electromyography (sEMG) allows a real-time, noninvasive assessment of the activation pattern of muscles during the activity performance (Gurney et al, 2016). Although sEMG has been used to evaluate the muscle activation patterns in several self-care (Meijer et al, 2014), productivity (Almeida, Cruz, Magna, & Ferrigno, 2013;Ferrigno, Cliquet, Magna, & Zoppi Filho, 2009), and leisure activities (Donoso Brown, McCoy, Fechko, Price, Gilbertson, & Moritz, 2014), few studies have analysed the different recruitment of muscle fibres during the performances of different hand function tests (Brorsson, Nilsdotter, Thorstensson, & Bremander, 2014;Calder, Galea, Wessel, MacDermid, & MacIntyre, 2011).…”

Objective/BackgroundOccupational therapists usually assess hand function through standardised tests, however, there is no consensus on how the scores assigned to hand dexterity can accurately measure hand function required for daily activities and few studies evaluate the movement patterns of the upper limbs during hand function tests. This study aimed to evaluate the differences in muscle activation patterns during the performance of three hand dexterity tests.MethodsTwenty university students underwent a surface electromyographic (sEMG) assessment of eight upper limb muscles during the performance of the box and blocks test (BEST), nine-hole peg test (9HPT), and functional dexterity test (FDT). The description and comparison of each muscle activity during the test performance, gender differences, and the correlation between individual muscles’ sEMG activity were analysed through appropriate statistics.ResultsIncreased activity of proximal muscles was found during the performance of BEST (p < .001). While a higher activation of the distal muscles occurred during the FDT and 9HPT performance, no differences were found between them. Comparisons of the sEMG activity revealed a significant increase in the muscle activation among women (p = .05). Strong and positive correlations (r > .5; p < .05) were observed between proximal and distal sEMG activities, suggesting a coordinate pattern of muscle activation during hand function tests.ConclusionThe results suggested the existence of differences in the muscle activation pattern during the performance of hand function evaluations. Occupational therapists should be aware of unique muscle requirements and its impact on the results of dexterity tests during hand function evaluation.

“…The importance of cutaneous feedback is higher in more sophisticated tasks (Ebied, Kemp, & Frostick, 2004). Volar-based wrist orthoses, either custom made or commercial, increase muscle activities of upper limbs compared with no orthoses (Ferrigno, Cliquet, Magna, & Zoppi Filho, 2009). Volarbased splints provide less cutaneous feedback at the wrist (Brenda, Lohman, & Shultz-Johnson, 2001), although mice with cutaneous feedback can enhance performance in computer tasks (Akamatsu, MacKenzie, & Hasbroucq, 1995;de Korte, de Kraker, Bongers, & van Lingen, 2008;de Korte, Huysmans, de Jong, van de Ven, & Ruijsendaal, 2012).…”
