OBJECTIVE:This study was designed to estimate the accuracy of the postural assessment software (PAS/SAPO) for measurement of corporal angles and distances as well as the inter- and intra-rater reliabilities.INTRODUCTION:Postural assessment software was developed as a subsidiary tool for postural assessment. It is easy to use and available in the public domain. Nonetheless, validation studies are lacking.METHODS:The study sample consisted of 88 pictures from 22 subjects, and each subject was assessed twice (1 week interval) by 5 blinded raters. Inter- and intra-rater reliabilities were estimated using the intraclass correlation coefficient. To estimate the accuracy of the software, an inanimate object was marked with hallmarks using pre-established parameters. Pictures of the object were rated, and values were checked against the known parameters.RESULTS:Inter-rater reliability was excellent for 41% of the variables and very good for 35%. Ten percent of the variables had acceptable reliability, and 14% were defined as non-acceptable. For intra-rater reliability, 44.8% of the measurements were considered to be excellent, 23.5% were very good, 12.4% were acceptable and 19.3% were considered non-acceptable. Angular measurements had a mean error analisys of 0.11°, and the mean error analisys for distance was 1.8 mm.DISCUSSION:Unacceptable intraclass correlation coefficient values typically used the vertical line as a reference, and this may have increased the inaccuracy of the estimates. Increased accuracies were obtained by younger raters with more sophisticated computer skills, suggesting that past experience influenced results.CONCLUSION:The postural assessment software was accurate for measuring corporal angles and distances and should be considered as a reliable tool for postural assessment.

OBJECTIVE:To contrast the efficacy of two exercise programs, segmental stabilization and strengthening of abdominal and trunk muscles, on pain, functional disability, and activation of the transversus abdominis muscle (TrA), in individuals with chronic low back pain.DESIGN:Our sample consisted of 30 individuals, randomly assigned to one of two treatment groups: segmental stabilization, where exercises focused on the TrA and lumbar multifidus muscles, and superficial strengthening, where exercises focused on the rectus abdominis, abdominus obliquus internus, abdominus obliquus externus, and erector spinae. Groups were examined to discovere whether the exercises created contrasts regarding pain (visual analogical scale and McGill pain questionnaire), functional disability (Oswestry disability questionnaire), and TrA muscle activation capacity (Pressure Biofeedback Unit  =  PBU). The program lasted 6 weeks, and 30‐minute sessions occurred twice a week. Analysis of variance was used for inter‐ and intra‐group comparisons. The significance level was established at 5%.RESULTS:As compared to baseline, both treatments were effective in relieving pain and improving disability (p<0.001). Those in the segmental stabilization group had significant gains for all variables when compared to the ST group (p<0.001), including TrA activation, where relative gains were 48.3% and ‐5.1%, respectively.CONCLUSION:Both techniques lessened pain and reduced disability. Segmental stabilization is superior to superficial strengthening for all variables. Superficial strengthening does not improve TrA activation capacity.

ResUMO Objetivo: Desenvolver uma versão transcultural do Fibromyalgia Impact Questionnaire (FIQ) para a população brasileira e analisar sua validade e eficácia quando aplicado em pacientes com fibromialgia. Pacientes e Métodos: Participaram do estudo 44 pacientes com fibromialgia (FM), diagnosticados segundo os critérios do American College of Rheumatology (ACR), 1990. Baseados nas orientações de Guillemin et al (22) , foram convidados quatro professores de língua inglesa, um reumatologista e dois fisioterapeutas. O procedimento seguiu as etapas: tradução inicial por dois professores de inglês, avaliação das duas traduções para uma versão única, versão para a língua inglesa por dois professores de inglês nativos, reunião de consenso com dois professores de inglês, reumatologista e fisioterapeutas para versão teste, avaliação da equivalência cultural, versão final, avaliação da confiabilidade e reprodutibilidade. A versão teste foi aplicada em 20 pacientes com FM, tendo em todas as questões o item "não-aplicável". Substituição de possíveis questões com mais de 15% de respostas "não-aplicável" por outras de mesmo conceito, resultando na versão final. Aplicação dessa versão em 24 pacientes com FM por dois avaliadores que fizeram a entrevista no mesmo dia com intervalo de uma hora e, após um período de sete dias da primeira avaliação, o questionário foi reaplicado pelo primeiro avaliador. Resultados: Na aplicação da versão teste não houve questões com mais de 15% de respostas "não-aplicável". Sendo assim, não foi mudado o texto para a versão final. Porém, houve dificuldade de compreensão das escalas visuais analógicas (questões 4 a 10). Com isso, foram acrescidas "carinhas" nos dois extremos: à esquerda uma "carinha" feliz e à direita, uma infeliz. Esse processo deu Validação da Versão Brasileira do Fibromyalgia Impact Questionnaire (FIQ) Validation of the Brazilian Version of the Fibromyalgia Impact Questionnaire (FIQ)

Cunha ACV, Burke TN, França FJR, Marques AP. Effect of global posture reeducation and of static stretching onto pain, range of motion, and quality of life in women with chronic neck pain: a random clinical trial. Clinics. 2008;63:763-70. PURPOSE:Compare the effect of conventional static stretching and muscle chain stretching, as proposed by the global posture reeducation method, in the manual therapy of patients with chronic neck pain. METHODS: Thirty-three female patients aged 35 to 60 years old, 31 of whom completed the program, were randomly divided into two groups: The global posture reeducation group (n=15) performed muscle chain stretching, while the conventional stretching group (n=16) performed conventional static muscle stretching. Both groups also underwent manual therapy. Patients were evaluated before and after treatment and at a six-week follow-up appointment and tested for pain intensity (by means of visual analog scale), range of motion (by goniometry), and health-related quality of life (by the SF-36 questionnaire). The treatment program consisted of two 1-hour individual sessions per week for six weeks. Data were statistically analyzed at a significance level of p<0.05. RESULTS: Significant pain relief and range of motion improvement were observed after treatment in both groups, with a slight reduction at follow-up time. Quality of life also improved after treatment, except for the global posture reeducation group in one domain; at follow-up, there was improvement in all domains, except that both groups reported increased pain. There were no significant differences between groups CONCLUSION: Conventional stretching and muscle chain stretching in association with manual therapy were equally effective in reducing pain and improving the range of motion and quality of life of female patients with chronic neck pain, both immediately after treatment and at a six-week follow-up, suggesting that stretching exercises should be prescribed to chronic neck pain patients.

The trial included a control group and two intervention groups, both of which received exercise programs created specifically for patients with FM. In clinical practice, we suggest including both modalities in an exercise therapy program for FM.

Temporomandibular dysfunctions (TMD) comprise a great number of disruptions that may affect the temporomandibular joint (TMJ), the masticatory muscles, or both. TMJ internal derangement is a specific type of TMD, of which the etiology and physiopathology are broadly unknown, but have been suggested to be linked to head, neck, and body posture factors. This study aimed at verifying possible relationships between body posture and TMJ internal derangements (TMJ-id), by comparing 30 subjects presenting typical TMJ-id signs to 20 healthy subjects. Subjects' clinical evaluations included anamnesis, stomatognatic system evaluation, and plotting analysis on body posture photographs. No statistically significant differences were found between the groups. Results do not support the assertion that body posture plays a role in causing or enhancing TMD; however, these results should be cautiously considered because of the small number of subjects evaluated and the many posture variables submitted to statistical procedures that lead to high standard deviations.

Our findings suggest that low level laser therapy when associated with exercises is effective in yielding pain relief, function and activity on patients with osteoarthritis of the knees.
