Title: Effects of PNF to change the motoric stereotype of the abduction in the shoulder joint Objectives: The aim of this thesis, which is conceived as a pilot experimental study is to verify the changes in the timing of selected muscles during stereotype abduction of the shoulder after performing repetitive cyclic motion by therapeutic method PNF if a specific number of repetitions of the movement is performed. Methods: This is a pilot experimental study, which was done on seven probands, 4 men and 3 women with an average age of 26.6 years. The surface EMG muscle activity was scanned on selected muscles during the motoric testing of stereotype of the abduction of the shoulder joint before and after the PNF techniques. The EMG signal was then analyzed and we evaluated the timing of muscles before and after the PNF techniques. The results were then compared in terms of both intra-individually and inter-individually comparison. Results: Results provided contradictory answers to the fundamental questions relating to changes in the timing of selected muscles after PNF techniques. In terms of the change in intra-individually timing after PNF hypothesis was proved. But from the perspective of inter-individually comparison the hypothesis was not proved. Keywords: PNF, surface electromyography, motion...

O exercício terapêutico tem o intuito de manter e ou melhorar as condições físicas ocasionadas pela dor lombar, entre as terapêuticas existe a Protocolo cinesioterapêutico (CIN), que usa exercícios combinados e o método Pilates (MP). OBJETIVO:Analisar o MP e FC na dor, resistência muscular, flexibilidade, força, recrutamento e co-contração dos músculos do tronco de idosas com DL, e comparar com um grupo de ações educativas. MÉTODOS:Participaram do estudo 41 idosas, com DL crônica, divididas em: Grupo Pilates (GP, n=14; 66,71±3,56anos), Grupo CIN (GCIN, n=13; 68,46±4,89anos) e Grupo ações educativas (GAE, n=14; 68,00±4,66anos). A avaliação foi composta pelos testes para: dor (Escala visual analógica), resistência muscular (Teste Biering-Sorensen-TBS), flexibilidade (Sentar e Alcançar, Ângulo Poplíteo), força muscular (FM) e eletromiografia dos músculos tronco (Iliocostal-IL, Multífido- MU, Oblíquo interno- OI). Ao fim da avaliação GP e GCIN realizaram 16 sessões em 8 semanas, e GAE quatro palestras em 8 semanas. A análise estatística usou os testes Shapiro-Wilk, Análise multivariada, analise de Variância Mista e correlação de Pearson (p≤0,05). RESULTADOS: No GP diminuiu a dor (p=0,003), maior resistência muscular (p<0,001) e FM(p=0,003), redução do recrutamento de IL direito durante TBS (p=0,05), co-contração de OI/MU esquerdo (p=0,004), aumento do recrutamento da FM de IL (p<0,001) e MU (p<0,001) direito. O GCIN obteve redução da dor (p=0,014), aumento do tempo de resistência (p=0,003) e FM (p=0,002), e diminuição do recrutamento de IL direito (p=0,008) no TBS e para IL esquerdo na FM (p=0,005). O GAE aumentou co-contração de OI/MU (p=0,02) no TBS e na FM dos músculos IL direito (p=0,007) e esquerdo (p=0,002) e MU direito (p<0,001). CONCLUSÃO: O MP e a FC são importantes na diminuição da dor, aumento do tempo de resistência muscular, FM e redução do recrutamento do IL no TBS de idosos com DL, no teste de FM o IL aumentou o recrutamento. A co-contração diminuiu com o Pilates e aumentou no GAE. / Chronic low back pain (LBP) in the length of the endurance and the strength of the extensor muscles of the trunk, flexibility, neuromuscular modifications. Therapeutic exercise is intended to maintain and improve as the possibilities are caused by LBP, among which there is a kinesiotherapeutic exercise (KT), which uses combined exercise, and Pilates Method (PM). OBJECTIVE: To analyze PM and KT in pain, muscular endurance, flexibility, strength, recruitment and co-contraction of the trunk muscles of elderly women with LBP, and compare with a group educational actions. METHODS:41 elderly women with chronic LBP were divided into: Pilates Group (PG, n = 14, 66.71 ± 3.56 years), KT Group (KTG, n = 13, 68.46 ± 4.89 years) and Group educational actions (EAG, n = 14; 68,00 ± 4,66 years). The tests was evaluated for: pain (Visual Scale Analogy), muscle endurance (Biering-Sorensen test-BST), flexibility (sitting and reaching, popliteal angle), muscle strength (MS) and electromyography of the trunk muscles ( Iliocostal-IL,Multifido- MU, Internal Oblique - OI). The PG and KTG evaluation were performed 8 weeks with16 session, and EAG 8 weeks with 4 lesion. A statistical analysis used the Shapiro-Wilk tests, Multivariate Analysis, Analysis of Variance and Pearson's Key (p≤0.05). RESULTS:PG decreased pain (p = 0.003), higher muscle endurance (p <0.001) and MS (p = 0.003), reduction of right IL recruitment during BST (p = 0.05), IO/MU co-contraction (p = 0.004), increased recruitment of IL FM (p <0.001) and right MU (p <0.001). KTG achieved a reduction in pain (p = 0.014), increased endurance (p = 0.003) and MS (p = 0.002), and decreased recruitment of right IL (p = 0.008) in BST and IL (p = 0.005). EAG increased the co-contraction of OI/MU (p = 0.02) in BST, right (p = 0.007) and left (p = 0.002) IL and right MU (p <0.001) in MS. CONCLUSION: PM and KT are important in reduction pain, increasing muscle strength and endurance, and reduction IL activation in BST, increase MU and IL activation in MS. Cocontraction decreased with PM and increased in EA. / CNPQ: 475806/2013-1
