Three-dimensional movement analysis was used to evaluate head and neck movement in patients with neck pain and matched controls. The aims were to further develop biomechanical models of head and neck kinematics, to investigate differences between subjects with non-specific neck pain and whiplash associated disorders (WAD), and to evaluate the potential of objective movement analysis as a decision support during diagnosis and follow-up of patients with neck pain. Fast, repetitive head movements (flexion, extension, rotation to the side) were studied in a group of 59 subjects with WAD and 56 controls. A back propagation artificial neural network classified vectors of collected movement variables from each individual according to group membership with a predictivity of 89%. The helical axis for head movement were analyzed in two groups of neck pain patients (21 with non-specific neck pain and 22 with WAD) and 24 matched controls. A moving time window with a cut-off angle of 4° was used to calculate finite helical axes. The centre of rotation of the finite axes (CR) was derived as the 3D intersection point of the finite axes. A downward migration of the axis during flexion/extension and a change of axis direction towards the end of the movements were observed. CR was at its most superior position during side rotations and at its most inferior during ball catching. This could relate to that side rotation was mainly done in the upper spine, while all cervical vertebrae were recruited to stabilize the head in the more complex catching task. Changes in movement strategy were observed in the neck pain groups: Neck pain subjects had lower mean velocities and ranges of movements as compared with controls during ball catching, which could relate to a stiffer body position in neck pain patients in order to stabilize the neck. In addition, the WAD group had a displaced axis position during head repositioning after flexion, while CR was displaced during fast side rotations in the non-specific neck pain group. Pain intensity correlated with axis and CR position, and may be one reason for the movement strategy changes. Increased amount of irregularities in the trajectory of the axis was found in the WAD group during head repositioning, fast repetitive head movements and catching. This together with an increased constant repositioning error during repositioning after flexion indicated motor control disturbances. A higher group standard deviation in neck pain groups indicated heterogeneity among subjects in this disturbance. Wireless motion sensors and electro-oculography was used simultaneously, as an initial step towards a portable system and towards a method to quantify head-eye co-ordination deficits in individuals with WAD. Twenty asymptomatic control subjects and six WAD subjects with eye disturbances (e.g. dizziness and double vision) were studied. The trial-to-trial repeatability was moderate to high for all evaluated variables (single intraclass correlation coefficients >0.4 in 28 of 32 variables). The WAD subjects demonstrated decreased head velocity, decreased range of head movement during gaze fixation and lowered head stability during head-eye co-ordination as possible deficits. In conclusion, kinematical analyses have a potential to be used as a support for physicians and physiotherapists for diagnosis and follow-up of neck pain patients. Specifically, the helical axis method gives information about how the movement is performed. However, a flexible motion capture system (for example based on wireless motion sensors) is needed. Combined analysis of several variables is preferable, as patients with different neck pain disorders seem to be a heterogeneous group.

Múltiples revisiones científicas han intentado determinar los factores pronósticos en la evolución del latigazo cervical sin llegar a un consenso. Nuestros resultados se han obtenido tras 8 años de estudio en pacientes controlados desde la primera visita en el servicio de Medicina Física y Rehabilitación del Hospital de Mataró. Se han utilizado escalas de valoración fáciles de cumplimentar y cuantificar para poder obtener los resultados en el mismo momento de la consulta. Este hecho es importante, ya que la mayoría de las escalas que se identifican en los artículos publicados son poco prácticas en la consulta diaria por la dificultad que conllevan en su cumplimentación y valoración. Los factores pronósticos que hemos identificado en nuestra muestran han sido: la edad, la presencia de “vértigos”, la intensidad del dolor cervical inicial valorada mediante la escala analógica visual y el grado de funcionalidad cervical inicial valorado mediante el Northwick Park Hospital Neck Pain Questionnaire.

Bakgrund: Nacksmärta är ett vanligt förekommande besvär och en av de främsta orsakerna till att söka vård hos fysioterapeut. Nackbesvär kan leda till förändringar i proprioception, både medveten och omedveten, vilket kan leda till en nedsatt balans. Undersökning av omedveten proprioception har gjorts genom att mäta posturalt svaj vid stimulering av muskelspolar via lokala muskelvibratorer i tidigare studier. Ingen studie har dock undersökt reliabiliteten vid stimulering av nack- och vadmuskler hos personer med respektive utan nacksmärta   Syfte: Studiens syfte var att utvärdera inter-day reliabilitet för posturalt svaj hos personer med eller utan nacksmärta genom att mäta CoP på WBB där deltagarna ges vibrationer på vader, nacke respektive underarmar.   Metod: 50 deltagare deltog i studien, 25 deltagare med nacksmärta och 25 friska kontroller. Deltagarnas CoP mättes på en WBB där deltagarnas förändring av CoP mättes innan, under och efter att vibrationer getts på vader, underarmar respektive nacken. Deltagarna testades vid två tillfällen med 7 dagars mellanrum. ICC2,1 användes för att beräknade relativ reliabilitet. Ett ICC-värde ≥ 0,75 bedöms som god reliabilitet. Absolut reliabilitet beräknades med SEM. Beroende t-test utfördes för att undersöka eventuell systematisk bias såsom adaptioner eller inlärningseffekter mellan testtillfälle 1och 2.   Resultat: Studiens resultat uppvisade en måttlig till utmärkt relativ reliabilitet (ICC = 0,69 - 0,89) för A/P amplituden för hela gruppen och SEM-värden var mellan 0,51 - 1,17 vilket utgör ca 20 - 30% av medelvärdet för de flesta svajvariablerna. En signifikant inlärningseffekt kunde ses för både A/P och M/L amplituden vid vibration av vadmuskulaturen (p = 0,015 - 0,017).   Slutsats: Studiens resultat visar på en acceptabel reliabilitet och testmetoden kan användas i såväl forskning som klinisk användning vid undersökning av posturalt svaj med eller utan vibration. / Background: Neck pain is a common occurrence and one of the main reasons for seeking care at a physiotherapist. Neck disorders can lead to changes in proprioception, both conscious and unconscious, which can lead to a reduced balance. Investigation of unconscious proprioception has been done by measuring postural sway in the stimulation of muscle spindles via local muscle vibrators in previous studies. However, no study has investigated the reliability of stimulation of neck and calf muscles in people with or without neck pain   Purpose: The purpose of the study was to evaluate inter-day reliability on postural sway in people with or without neck pain by measuring CoP on WBB where participants receive vibration on the calf, neck and forearms.   Method: 50 participants participated in the study, 25 participants with neck pain and 25 healthy controls. Participants change of CoP was measured before, during and after vibration was given to calf, forearm and neck. Participants were tested on two occasions at 7-day intervals. ICC2,1 was used to calculate relative reliability. An ICC value ≥ 0.75 is considered to be good reliability. Absolute reliability was calculated with SEM. Dependent t-test was performed to investigate any systematic bias such as adaptations or learning effects between test 1 and 2.   Results: The results of the study showed a moderate to excellent relative reliability (ICC = 0.69 - 0.89) for the A/P amplitude and SEM values ​​were between 0.51 - 1.17 which represents about 20-30% of the mean for most sway variables. A significant learning effect could be seen for both the A/P and M/L amplitude in vibration of the calf muscles (p = 0.015-0.017).   Conclusion: The results of the study demonstrate acceptable reliability and the test method can be used in research and clinical to investigate postural sway with or without vibration.

A compreensão dos fatores relacionados à presença de dor provocada por tumores malignos na região da cabeça e do pescoço possibilita o estabelecimento de métodos diagnósticos, terapêuticos e prognósticos visando a pronta recuperação dos pacientes e melhor qualidade de vida. Um importante fator algogênico é a invasão de tecidos nervosos pelos carcinomas que pode ocorrer precocemente em níveis microscópicos ou tardiamente por disseminação pelos troncos nervosos. O objetivo deste trabalho foi estudar a presença de dor e invasão perineural microscópica em pacientes portadores de carcinomas da cabeça e do pescoço, correlacionando-as entre si e com outras variáveis clínicas e anatomopatológicas como sexo, cor, idade, intensidade da dor, índice de dor, tipo histopatológico, localização tumoral, estadiamento, infiltração óssea, tamanho do tumor e comprometimento de linfonodos. Foram estudados, através de amostra aleatória, 50 pacientes consecutivos, com diagnóstico histopatológico comprovado através de biópsia, de carcinoma na região da cabeça e do pescoço, cujo tratamento envolveu a tentativa cirúrgica de ressecção tumoral completa. No estudo foi realizada, antes do ato cirúrgico, entrevista utilizando-se uma ficha clínica padronizada elaborada especialmente para o trabalho. Outras informações foram obtidas do prontuário da instituição. Após a remoção cirúrgica o material foi enviado para o estudo anatomopatológico de rotina e depois revisado quanto à presença de invasão perineural. Esta verificação foi feita pela análise em hematoxilina-eosina e pela técnica imuno-histoquímica utilizando o anticorpo antiproteína S-100. Dos 50 pacientes analisados 36 (72%) eram do sexo masculino e 14 (28%) do sexo feminino. A idade média foi de 54,7 anos. Os leucodermas foram predominantes com 70%. Quando interrogados sobre a presença de dor nos últimos 30 dias, 27 pacientes (54%) responderam positivamente. Houve presença de invasão perineural em 20 indivíduos (40%). A investigação anatomopatológica do estadiamento tumoral mostrou maior freqüência dos carcinomas de estádio I e do tipo células escamosas moderadamente diferenciado. Quanto à localização dos tumores, houve predomínio de comprometimento em boca e laringe. Não foi encontrada diferença significativa entre pacientes com e sem dor quanto à proporção de casos onde existia invasão perineural. Não houve correlação estatística entre presença de dor e sexo, cor, idade, tipo histopatológico, envolvimento ósseo, estadiamento tumoral ou linfonodos comprometidos. Houve diferença significativa entre os locais laringe e pele, e os tamanhos T1 e T2 quanto à proporção de pacientes com dor. Não houve correlação estatística entre invasão perineural e sexo, cor, idade, EAV, PRI, tipo histológico, envolvimento ósseo, estadiamento, tamanho e nodos comprometidos. A correlação entre invasão perineural e localização do tumor mostrou diferença significativa entre laringe e pele quanto à proporção de casos com invasão perineural (p = 0,033). Foi estudada ainda, a correlação entre as variáveis semiquantitativas EAV e PRI, e, pelos coeficientes de correlação de Spearman, poderíamos afirmar que houve relação entre EAV e PRI (r= 0,934; p < 0,001). Não se pode considerar a invasão neural microscópica como fator isolado na produção de dor em cabeça e pescoço. São necessários novos trabalhos que elucidem os mecanismos desencadeadores da dor e a diferença individual do limiar de dor. Neste trabalho constatou-se diferença estatística significativa quanto à presença de dor e invasão perineural comparando-se a localização dos carcinomas em pele e laringe. / Keeping in mind a better quality of life and quick recovery for the patient, the understanding of the intervening factors related to the presence of pain caused by malignant tumors in the head and neck area makes possible to establish diagnosis, therapeutic and prognosis methods in these cases. One important algogenic factor is the invasion of the nervous tissues by the carcinomas, which can happen early in a microscopic level or lately by dissemination through nerve trunks. The aim of this work is to study the presence of pain and microscopic perineural invasion in patients bearing head and neck carcinomas, basically correlating them to each other and to other clinical and atomopathological variables i.e. sex, ethnicity, age, pain intensity, McGill index, histological type, tumor location, staging, bone infiltration, tumor size and lymph node involvement. In this work, we studied a random sample of 50 consecutive patients with confirmed histopathologic diagnosis (through biopsy) of head and neck carcinoma, whose treatment involved the attempt of complete surgical tumor resection. Before the surgical procedure, we interviewed each patient using a standard clinical questionnaire especially designed for the study. Additional information was obtained through patients medical records in the institution. After surgical resection, the material was sent for anatomopathological routine study and then checked for the presence of perineural invasion. The revision process involved analysis via both haematoxylin-eosin stain and immunohistochemical technique using S-100 anti-protein antibody. Thirty-six (72%)from 50 analysed patients were male and 14 (28%) female. The average age was 54.7 years old. White ethnicity was prevalent within 70% of the cases. When asked about the presence of pain within the previous 30 days, 27 patients (54%) answered positively. Perineural invasion was present in 20 individuals (40%). The anatomopathological investigation of tumoral staging showed a greater frequency of stage 1 carcinomas and of the moderately differentiated squamous cell type. With reference to the location of the tumors, there was a prevalence of mouth and larynx involvement. We did not find significant difference between patients with and without pain regarding cases showing perineural invasion. Likewise, there was no statistical correlation between pain presence and gender, ethnicity, age, histological type, bone involvement, tumoral staging or lymph node invasion. There was a significant difference between larynx and skin locations, and T1 and T2 sizes, regarding the proportion of patients referring pain. No statistical correlation was found between perineural invasion and gender, ethnicity, age, VAS, McGill index, histological type, bone involvement, staging, size or affected lymph nodes. The correlation between perineural invasion and tumor location showed significant difference between larynx and skin regarding the proportion of cases showing perineural invasion (p = 0.033). The correlation between McGill index and VAS semi quantitative variable was also studied, and the Spearman correlation coefficient showed a relationship between VAS and McGill index (r = 0.934; p < 0.001). Thus, one cannot consider microscopic neural invasion as an isolated factor in the production of pain in head and neck. New researches are necessary to bring to light the mechanisms that trigger pain, or the individual differences in pain threshold. This work also revealed a significant statistical difference regarding the presence of pain and perineural invasion when comparing larynx and skin carcinomas.

A sua presença é associada à rigidez muscular e estresse e pode influenciar a qualidade de vida de pacientes sintomáticos. Imagens ultrassonográficas do tecido disfuncional têm sido realizadas com o intuito de avaliar objetivamente o Pg. Com o objetivo de avaliar o efeito da acupuntura e da eletroacupuntura no tratamento da DM da parte superior do músculo trapézio, sessenta voluntárias com idade entre 18 e 40 anos, índice de massa corpórea entre 18 e 30 Kg/m2, com pelo menos um ponto gatilho na parte superior do músculo trapézio, dor local ou referida por mais de seis meses foram randomizadas em três grupos: eletroacupuntura (EA), acupuntura (AC) e acupuntura SHAM (SHAM). O avaliador e as voluntárias eram cegos aos tratamentos. Os pontos de acupuntura utilizados foram: VB20, VB21, F3 e IG4, além de no máximo, 2 pontos ashi em cada lado do trapézio superior. A efetividade do tratamento, assim como a manutenção dos resultados até um mês após o final do tratamento, foram avaliada pela intensidade de dor (escala visual analógica: EVA), amplitude de movimento cervical (fleximetria), qualidade de vida (SF-36), estresse (área abaixo da curva: AUCG; resposta do cortisol ao acordar: CAR), imagem de ultrassom (área do Pg). De acordo com sua distribuição os dados foram analisados pelos testes: teste-t pareado, Wilcoxon signed rank, ANOVA para medidas repetidas ou teste de Friedman, ANOVA ou Kruskal Wallis. Foi aplicado o teste de correlação de Pearson. O nível de significância foi de ?= 0,05. Foi observada redução na dor geral (DG) nos grupos EAC (P<0.001) e AC (P<0.001) após todas as sessões. Na reavaliação, a dor no trapézio direito (TPzD) diminuiu para os grupos EA (P<0.001) e AC (P=0.025), já no trapézio esquerdo (TPzE), apenas o grupo EA mostrou melhora (P<0.001). Em relação à DG correu interação dos fatores "fase de avaliação" e "grupo" para AC e EAC, e para dor no TPzD e E apenas para o grupo EA. Após o tratamento houve aumento da rotação para a esquerda no grupo EA (P=0.049), e aumento da inclinação e rotação para a direita no grupo AC (P=0.005; P=0.032). Houve aumento da AUCG (P=0.006) e CAR (P<0.001) no grupo AC. Em relação aos dados obtidos pelo SF-36, o grupo SHAM apresentou aumento significativo da dor (P=0.005); os grupos EA e AC mostraram aumento nos mesmos domínios, com valores respectivos de P: capacidade funcional (P=0.011; P=0.016), aspectos físicos (P=0.027; P=0.13), dor (P=0.010; P=0.003), estado geral da saúde (P=0.017; P=0.011), vitalidade (P=0.010; P=0.011), saúde mental (P=0.018; P=0.014) e componente físicos (P=0.019; 0.002). Ocorreu diminuição na área do ponto gatilho (US) nos grupos EA (TPzD: P<0.001; TPzE: P=0.001) e AC (TPzD e TPzE P<0.001), e no grupo SHAM apenas no TPzE (P=0.036). A EA se mostrou mais eficaz no alívio da dor quando comparada aos outros grupos. Tanto AC quanto EA foram eficazes na melhora da morfologia do tecido muscular (US) e da qualidade de vida. A AC parece ser mais indicada na diminuição do estresse e na melhora da amplitude de movimento cervical em mulheres com dor miofascial no trapézio superior / Abstract: Myofascial pain (MP), caused by myofascial trigger points (MTrP), is of the main cause of headache and neck pain. It is associated with muscular stiffness, stress and can influence the quality of life of symptomatic patients. Ultrasound images of dysfunctional tissue have been used aiming to objectively evaluate the myofascia trigger point. Aiming to evaluate the effect of acupuncture and electroacupuncture on the treatment of MP at the upper trapezius muscle, sixty women aged between 18 and 40 years old, body max index between 19 and 30 Kg/m2, presenting at least one trigger point at the upper trapezius and local or referred pain for more than six months were randomized in to and three groups: electroacupuncture (EAC), acupuncture (AC) and SHAM-acupuncture (SHAM). Both examiner (CEEM) and volunteers were blinded to the treatments. The selected acupoints were VB20, VB21, F3 and IG4, besides a maximum of 2 "ashi points" in each upper trapezius. The effectiveness of treatment (eight sessions), as well as it maintenance till one month follow up, were evaluated concerning the intensity of pain (Visual analog scale: VAS), range of motion (fleximetry), quality of life (SF-36), stress (area under the curve to the ground: AUCG; cortisol awaking response: CAR) and ultrasound image (area of MTrP). Influencing factors and the menstrual cycle phases were monitored. According to its distribution, data were analyzed by pared t-test, Wilcoxon signed rank, ANOVA repeated measures, Friedman test, ANOVA or Kruskal Wallis. Pearson¿s correlation was applied. The level of significance was set in ?= 0.05. It was observed reduction on general pain (GP) on treated groups after all sessions (EA: P<0.001; AC: P<0.001). After treatment, intensity of pain on the right trapezius (RTPz) decreased in the EA (P<0.001) and AC (P=0.025) groups, but on the left trapezius (LTPz) it was only observed in the EA group (P<0.001). There was interaction of factor "time of evaluation" with factor "group" for GP in the AC and EA groups; and for pain at the RTPz and LTPz only in the EA group. There was increase on rotation to the left in the EA group (P=0.049) and on inclination and rotation to the right on group AC (P=0.005; P=0.032). There was increase on AUCG (P=0.006) and CAR (P<0.001) in the AC group. While SHAM presented significant increase only on bodily pain (P=0.005), EA and AC showed increase at the same following domains, with respectively P values: physical function (P=0.011; P=0.016), role physical (P=0.027; P=0.13), bodily pain (P=0.010; P=0.003), general health (P=0.017; P=0.011), vitality (P=0.010; P=0.011), mental health (P=0.018; P=0.014) and physical components (P=0.019; 0.002). It was observed a decrease on MTrP area (US) in the groups EA (TPzD: P<0.001; TPzE: P=0.001) and AC (RTPz e LTPz P<0.001), and in the SHAM groups only at the LTPz (P=0.036). The EA group has shown to be more effective on pain relief when compared to other groups. Both AC and EA were effectiveness improving tissue morphology (US) and quality of life. AC seems to be more indicated to the decrease stress and increase cervical range of motion than EA in women with myofascial pain at the upper trapezius / Doutorado / Anatomia / Doutora em Biologia Buco-Dental

Abstract The etiology of musculoskeletal disorders remains largely unclear, pain being the predominant complaint. The prevalence of neck pain (NP), shoulder pain (SP), and low back pain (LBP) increases drastically during adolescence. Potentially modifiable risk factors of NP, SP, and LBP should be identified at that age. First, this study evaluated the prevalence of NP, SP, LBP and peripheral pains (upper or lower extremities) and the prevalence of multiple pains. Second, the study determined the role of a set of potentially modifiable risk factors for adolescents’ NP, SP, and LBP (physical activity, inactivity, sedentary activities in cross-sectional study design and quantity and quality of sleep in follow-up study design). The study population belongs to the 1986 Northern Finland Birth Cohort (NFBC 1986), consisting of 9,479 children with an expected date of birth between July 1, 1985 and June 30, 1986 in the two northernmost provinces of Finland, Oulu and Lapland. NP, SP, and LBP were common at the ages 16 and 18, while medical consultations for these pains were less frequent. The prevalence of pain increased with age. Peripheral pains were rare. Surprisingly many adolescents reported multiple musculoskeletal pains. Girls were more likely to report pain than boys. Both low and high level of physical activity, some risk sport activities, high amount of sedentary activities, and insufficient quantity and quality of sleep increased the risk of NP, SP, and LBP in adolescence. It may be possible to reduce the occurrence of musculoskeletal pain by having a positive impact on potentially modifiable risk factors, such as physical activity, sedentary activities and sleep hygiene. Therefore, intervention studies focusing on these factors are needed in the future. / Tiivistelmä Useimmiten tuki- ja liikuntaelinsairauksien tarkka syy jää epäselväksi ja kipu on niiden pääasiallinen ilmentymä. Niska-, hartia- ja alaselkäkipujen esiintyvyys väestössä nousee merkittävästi teini-iässä. Tämän vuoksi niska-, hartia- ja alaselkäkivun riskitekijöitä tulisikin tutkia nuoruudessa, jotta niihin päästäisiin vaikuttamaan ajoissa. Tässä väitöskirjassa selvitettiin niska-, hartia-, alaselkä- ja laaja-alaisten tuki- ja liikuntaelinkipujen esiintyvyyttä nuorilla. Päätavoite oli kuitenkin tutkia liikunnan, eri urheilulajien, liikkumattomuuden, istumisen ja unen laadun ja määrän yhteyttä niska-, hartia- ja alaselkäkipujen esiintyvyyteen. Tutkimusaineisto muodostui Pohjois-Suomen syntymäkohortin 1986 nuorista, joiden laskettu syntymäaika oli 1.7.1985–30.6.1986. Nuorille lähetettiin 16-vuotiaana postikysely, joka sisälsi tuki- ja liikuntaelinoirekyselyn, kysymyksiä liikunnan, istumisen ja unen määrästä ja laadusta, sekä muista elämäntavoista. Kahden vuoden kuluttua, 18-vuotiaana lähetettiin toinen kysely joka sisälsi mm. tuki- ja liikuntaelinoirekyselyn. Tulokset osoittavat että niska-, hartia- ja alaselkäkivut olivat yleisiä nuoruudessa, joskin hoitoa vaativat kivut ja raajojen kipuoireilu olivat harvinaisia. Laaja-alaiset tuki- ja liikuntaelinkivut olivat odotettua yleisempiä. Tytöt oireilivat enemmän kuin pojat ja oireilu lisääntyi iän myötä. Hyvin aktiivinen liikunnan harrastaminen (6h/vko tai enemmän ripeää liikuntaa) ja erityisesti tietyt riskilajit olivat yhteydessä suurempaan niska-, hartia- ja alaselkäkipujen esiintyvyyteen. Samoin suuri istumisen määrä, riittämätön uni ja huono unen laatu lisäsivät kipujen todennäköisyyttä. Nuorten tuki- ja liikuntaelinkipuja voitaisiin mahdollisesti vähentää vaikuttamalla muunneltavissa oleviin riskitekijöihin, kuten vähentämällä istumista, lisäämällä terveysliikuntaa, sekä parantamalla unitottumuksia. Tämän takia jatkossa tarvitaan näihin riskitekijöihin kohdistuvia interventiotutkimuksia.

M.Tech. (Chiropractic) / Purpose: The aim of this study was to look at the effectiveness of massage with MYO₂ gel in conjunction with Spinal Manipulative Therapy (SMT) for the treatment of patients with posterior mechanical neck pain, with regards to pain, disability and cervical spine range of motion. The effect of these treatments was evaluated using a questionnaire consisting of Visual Analogue Scale (VAS) and a Vernon-Mior Neck Pain and Disability Index Questionnaire, and by measuring cervical spine range of motion using a cervical range of motion (CROM) measuring device. Method: 30 participants with posterior mechanical neck pain were randomly divided into two groups based on the order they start the study in. Group A – control group, received SMT to the cervical spine, followed by massage with ultrasound gel over the upper trapezius muscle and the area of the posterior neck musculature. Group B – experimental group, received SMT of the cervical spine, followed by massage with MYO₂ gel over the upper trapezius muscle and the area of the posterior neck musculature. Participants were treated six times out of a total of seven sessions, over a maximum three week period. Procedure: Subjective data was collected at the beginning of the first and fourth and seventh consultations. This was done by means of a Visual Analogue Scale (VAS) and a Vernon- Mior Neck Pain and Disability Index Questionnaire in order to assess pain and disability levels. Objective data was collected at the beginning of the first, fourth session, and seventh consultation by means of measuring cervical spine range of motion using a cervical range of motion (CROM) measuring device. Analysis of collected data was performed by a statistician from STATKON; a department of the University of Johannesburg. Results: When comparing the VAS of the initial with the final consultation it showed a statistically significant difference in both groups. This indicated that both interventions were effective in decreasing the perceived level of neck pain (VAS score). When comparing the Neck Pain and Disability Index of the initial with the final consultation it showed a statistically significant difference in both groups. This indicated that both interventions were effective in decreasing neck pain and disability of the cervical spine. When comparing the Cervical Range of Motion (CROM) of the initial consultation with the final consultation it showed a statistically significant improvement in both groups in all directions of motion. Both groups resulted in an increase in range of motion over time. Group B had a greater average CROM percentage increase of 28.60% average compared to Group A which had an average percentage increase of 22.25%.

Thus, the objective of this study was to evaluate the pain, cervical mobility and electromyographic activity of the upper trapezius (UT) muscle in patients with NS-NP pre and post immediately visceral manipulation (VM) and after 7 days. This study was a placebo-controlled, randomized, blind study of subjects with IC. Thirty individuals with NS-NP were divided into two groups: Manipulation Group: 15 subjects treated with visceral manipulation and Placebo Group: 15 subjects receiving placebo treatment. The possible effects of the therapy were verified by the analysis of the pain performed through the Numeric Pain Rating Scale (NPRS) and by the measurement of the area of pain, the electromyographic activity of the UT muscle and the cervical mobility. In the analysis of mobility and pain verified by the area of pain, NPRS and algometry, no significant difference (p> 0.05) was found between the studied groups. The results obtained in the ANOVA of the group interaction (F = 0.09, p = 0.05, p2 <0.001) and treatment vs group (F = 0.69, p = 0.49, p2 = 0.006), showed no influence of VM on the amplitude of the electromyographic signal of the UT muscle. The present study demonstrated that a single intervention of visceral manipulation, of the stomach and liver, does not alter the pain, cervical mobility and electromyographic signal of trapezius muscle descending fibers, both in immediate posttraining and after 7 days. / A cervicalgia inespecífica (CI) pode ser decorrente de causas multifatoriais, como por exemplo, uma alteração na mobilidade ou funcionamento de vísceras que se encontram na cavidade abdominal, devido à uma possível relação neural entre essas duas regiões. O objetivo desse estudo foi avaliar a dor, mobilidade cervical e a atividade eletromiográfica (EMG) do músculo trapézio fibras descendentes (TFD) em pacientes com CI pré e pós mobilização visceral (MV) imediata e após 7 dias. Esse foi um estudo, placebo controlado, randomizado cego, composto por 30 indivíduos com CI distribuídos em dois grupos: GM: 15 indivíduos tratados com mobilização visceral e GP: 15 indivíduos que receberam tratamento placebo. Os possíveis efeitos da MV foram verificados pela análise da dor realizada por meio da Escala Numérica Verbal de Dor (ENVD) e pela mensuração da área de dor, pela atividade eletromiográfica do músculo TFD e pela mobilidade cervical. Na análise da mobilidade e da dor verificada pela área da dor, ENVD e algometria, não foi encontrada nenhuma diferença significativa (p>0,05) entre os grupos estudados. Os resultados obtidos na ANOVA das interações grupo (F=0,09, p=0,05; p2 <0,001) e tratamento vs grupo (F=0,69, p=0,49; p2 =0,006), não demostraram influência da MV na amplitude do sinal EMG do músculo TFD. O presente estudo demonstrou que uma única intervenção de manipulação visceral, do estômago e fígado, não altera a dor, mobilidade cervical e sinal eletromiográfico do músculo trapézio fibras descendentes, tanto no pós tratamento imediato, como após 7 dias.
