- Impacto da utilização de ortóteses de neoprene, em contexto laboral, em indivíduos com disfunções no punho e/ou mãoPublication . Martins, Rafael; Fernandes, Ângela; Branco, Catarina Aguiar; Sousa, HelenaO nosso objetivo foi avaliar o impacto da utilização de ortóteses de neoprene em disfunções do punho e/ou mão, em contexto laboral. Amostra não probabilística por conveniência, constituída por 15 indivíduos adultos. Do total da amostra, 7 indivíduos pertencem ao grupo controlo e 8 indivíduos ao grupo de intervenção. As variáveis consideradas neste estudo foram a força muscular manual e de pinças, sensibilidade protetora das mãos, dor e funcionalidade do membro superior. Para a medição destas variáveis foram aplicados o Questionário Nórdico Musculosquelético, Quickdash, Teste de Monofilamento de Semmes- Weinstein, dinamómetro manual (Jamar) e pinçometro (Jamar). Para os participantes do grupo de intervenção, foram confecionadas duas ortóteses em neoprene, uma para cada mão, abrangendo as articulações do polegar e punho, com 5,5 mm de espessura; este grupo também teve educação terapêutica. Em relação à avaliação da sensibilidade no primeiro momento de avaliação, não foram observadas diferenças significativas entre os grupos, com exceção da área S1 da mão esquerda. De forma global, o grupo de intervenção apresentou maiores ganhos do que o grupo controlo, com diferenças estatisticamente significativas na pinça digital das mãos direita e esquerda, zonas de sensibilidade S2 da mão direita e S5 da mão esquerda e na funcionalidade do membro superior. Com a realização deste estudo, constatou-se que o grupo de intervenção apresentou melhorias generalizadas em todas as variáveis, o que pode sugerir eficácia da utilização das ortóteses de neoprene em contexto laboral.
- Total forearm support during a typing task may reduce the risk of Trapezius' Myalgia development.Publication . Santiago, Rui José; Baptista, João Santos; Magalhães, André; Costa, José TorresEvaluate the influence of alternating the position of the upper limbs, between fully supported and unsupported forearms, in the Upper Trapezius (UT) activity during a typing task on a straight-edged desk. Ergonomic barriers, such as reduced desk area, is one of the reasons that force computer users to work without supporting their forearms. Unsupported forearms may lead to increased UT muscle fatigue, increasing the potential for lesions, with Trapezius Myalgia (TM) being a possible outcome. 15 healthy volunteers were assessed (6 females, average age of 3,7 ± 9,5 years old). The protocol included an alternated position of forearms every 5 min between fully supported and unsupported forearms, with a 20-min total duration of a typing task. Surface electromyography readings were collected from both UTs. Significant differences were found in the variation of the EMG signal between the two positions for the non-dominant arm after 10 min (p < .05) of typing. The non-dominant UT registered higher levels of activity than the dominant UT. Supported forearms reduced the electrical activity in both UTs, with a greater difference in the non-dominant. This study consolidates the current knowledge that unsupported upper limb during typing tasks significantly increases UT’s electrical activity. By fully supporting the forearm, that activity is reduced. Females and the non-dominant UT showed higher electrical activity, potentially increasing the risk of developing TM. Healthcare providers, safety and health professionals, and ergonomists should be mindful of the forearm position when advising computer users to prevent TM.
- Manual but not instrument-assisted cervical manipulation reduces pain and disability in subjects with nonspecific neck pain: double-blinded, randomized clinical trialPublication . Nogueira, Nuno; Oliveira-Campelo, Natália; Torres, Rui; Sousa, Andreia S. P.; Ribeiro, FernandoThere is limited evidence comparing the effects of manual and instrumented-assisted manipulations among adults with neck pain. Our purpose was to determine the effects of a multisession regime of manual and instrument-assisted cervical manipulation on pain, disability, perception of change, and muscle properties in subjects with nonspecific neck pain. We conducted a double-blind, randomized, placebo-controlled study in 32 subjects with nonspecific neck pain. Two groups received three sessions of cervical (C3/C4) manipulation, one group manual and the other instrument-assisted, a third group received three sessions of sham manipulation, and a fourth group served as a control. Self-reported pain, pressure pain thresholds, neck disability, patient perception of change, and properties (tonus, stiffness, and elasticity) of the upper trapezius and biceps brachii were assessed at baseline, immediately after the first session and 15 days after the end of the intervention. After the end of the intervention, the percentage of changes in the visual analogue scale score, Neck Disability Index, and Patient Global Perception of Change score were significantly higher in the manual group in comparison with the other groups (p < 0.05). No between-group differences were observed in the percentage of changes in tonus, stiffness, and elasticity of the four muscles at the end of the intervention. We concluded that three sessions of C3/C4 manual manipulation improved pain and disability in subjects with nonspecific neck pain.
- Impact of a ten-minute typing task in the development of trapezius myalgiaPublication . Santiago, Rui José; Baptista, João Santos; Magalhães, André; Costa, José TorresComputer use, as in typing, might contribute to trapezius myalgia (TM) development by increasing upper trapezius (UT) muscle fatigue. The purpose of this study is to investigate whether 10 min of performing a typing task by a population at risk would show significant changes in surface electromyography (sEMG) and pressure pain threshold (PPT) measurements. Supported and unsupported forearms postures are compared. Sixteen asymptomatic volunteers with minimum daily use of a computer of 5 h were randomized into two groups: fully supported forearms (n = 8) and unsupported forearms (n = 8). The protocol consisted of 10 min of a typing task, and the workstation was set according to the usual participant profile. sEMG and PPT readings were collected from both UT muscles. PPT and sEMG readings were not significantly different among the two groups. Supported forearms had less reduction of PPT and a smaller increase in electrical activity. Ten minutes of typing seems insufficient to observe any significant changes that could lead to TM development.
- Instrumentation used to assess pain in osteopathic interventions: A critical literature reviewPublication . Santiago, Rui José; Esteves, Jorge; Baptista, João Santos; Marques, António Torres; Costa, José TorresA variety of different scales have been used to measure the intensity of pain in osteopathic-specific clinical studies; however, the criteria for the options are not always clear or reported. To compare the different questionnaires used by researchers for assessing the intensity of pain in clinical trials in osteopathy and analyse the reasons for their choice. Methods: A systematic literature search was conducted using 7 electronic databases (SCOPUS, Cochrane Central, MEDLINE, PEDro, OSTMED.DR, ScienceDirect, and Web of Science) for Randomized Controlled Trial (RCT) articles, studying the efficacy/effectiveness of Osteopathic Manipulative Treatment (OMT) in reducing pain intensity. Only articles in English from 2012 to 2019 were selected. We used the Jadad score to assess the risk of bias. 130 studies were initially identified with a total of 26 included in this review. Sixteen studies used the Visual Analog Scale (VAS), four the Numeric Rating Scale (NRS), the remaining used other options. Researchers did not always provide an appropriate justification for their chosen evaluation instrument. The overall quality of the studies was considered moderate. Researchers in the field of osteopathy and other health care professions should provide a clear rationale for their chosen tools for measuring the intensity of pain, and these should align with the study design and objectives.
- Results of a feasibility randomised controlled trial of osteopathy on neck-shoulder pain in computer usersPublication . Santiago, Rui José; Esteves, Jorge Eduardo; Baptista, João Santos; Magalhães, André; Costa, José TorresComputer use is a well-known source of chronic pain, leading to absenteeism and reduced productivity and well-being. This study evaluated the feasibility of conducting a full-scale randomised controlled trial. Several methodological variables defined trial feasibility. Of 77 participants interested, 30 were included and randomised into three groups of ten. All participants concluded the study, and all the data was analysed. The feasibility outcomes were deemed appropriate. No adverse events or severe side effects were reported or identified. Studying the efficacy of osteopathic consultation on computer users by conducting an RCT is feasible and safe. With adjustments, a full-scale study can be designed.
- The portuguese Osteopathic Practitioners Estimates and RAtes (OPERA): A cross-sectional surveyPublication . Santiago, Rui José; Nunes, Alexandre; Esteves, Jorge Eduardo; Cerritelli, Francesco; Verbeeck, Johan; Lopes, Sónia; Paquete, Manuel; van Dun, PatrickA voluntary online-based survey was distributed across Portugal between February and June 2020. The survey, composed of 52 questions and seven sections, was formally translated from English to Portuguese and adapted from the original version. Two pilot tests evaluated cultural adaptation and reproducibility. Adult, self-defined osteopaths working in Portugal were eligible. Recruitment of participants was performed through social media and an e-based campaign. A total of 222 osteopaths participated in the study, 143 were male (64%), aging between 30 and 39 years (42%), mainly working in Lisbon (30%). Most respondents had preliminary healthcare training (68%), mainly as massage therapists. The majority of respondents were self-employed (83%), owner of a clinic (55%) and working alone (59%). The median number of consultations per week was 21–25 and respondents scheduled 46–60 min for each consultation. The majority of patients seek care for lumbar (52%), cervical (38%) and upper spine (38%) complaints. Although most respondents experience a strong osteopathic identity, they do not advertise themselves exclusively as osteopaths. This study represents the first nationwide document to determine osteopaths' characteristics in Portugal. The study results provide a basis for future surveys that will include cohorts with higher levels of education, as well as findings from other European countries.

- The influence of gait cadence on the ground reaction forces and plantar pressures during load carriage of young adultsPublication . Castro, Marcelo; Figueiredo, Maria Cristina; Abreu, Sofia; Sousa, Helena; Machado, Leandro; Santos, Rubim; Vilas-Boas, João PauloBiomechanical gait parameters—ground reaction forces (GRFs) and plantar pressures—during load carriage of young adults were compared at a low gait cadence and a high gait cadence. Differences between load carriage and normal walking during both gait cadences were also assessed. A force plate and an in-shoe plantar pressure system were used to assess 60 adults while they were walking either normally (unloaded condition) or wearing a backpack (loaded condition) at low (70 steps per minute) and high gait cadences (120 steps per minute). GRF and plantar pressure peaks were scaled to body weight (or body weight plus backpack weight). With medium to high effect sizes we found greater anterior-posterior and vertical GRFs and greater plantar pressure peaks in the rearfoot, forefoot and hallux when the participants walked carrying a backpack at high gait cadences compared to walking at low gait cadences. Differences between loaded and unloaded conditions in both gait cadences were also observed.
- In-shoe plantar pressures and ground reaction forces during overweight adults' overground walkingPublication . Castro, Marcelo Peduzzi; Abreu, Sofia; Sousa, Helena; Machado, Leandro; Santos, Rubim; Vilas Boas, JoãoPurpose: Because walking is highly recommended for prevention and treatment of obesity and some of its biomechanical aspects are not clearly understood for overweight people, we compared the absolute and normalized ground reaction forces (GRF), plantar pressures, and temporal parameters of normal-weight and overweight participants during overground walking. Method: A force plate and an in-shoe pressure system were used to record GRF, plantar pressures (foot divided in 10 regions), and temporal parameters of 17 overweight adults and 17 gender-matched normal-weight adults while walking. Results: With high effect sizes, the overweight participants showed higher absolute medial-lateral and vertical GRF and pressure peaks in the central rearfoot, lateral midfoot, and lateral and central forefoot. However, analyzing normalized (scaled to body weight) data, the overweight participants showed lower vertical and anterior-posterior GRF and lower pressure peaks in the medial rearfoot and hallux, but the lateral forefoot peaks continued to be greater compared with normal-weight participants. Time of occurrence of medial-lateral GRF and pressure peaks in the midfoot occurred later in overweight individuals. Conclusions: The overweight participants adapted their gait pattern to minimize the consequences of the higher vertical and propulsive GRF in their musculoskeletal system. However, they were not able to improve their balance as indicated by medial-lateral GRF. The overweight participants showed higher absolute pressure peaks in 4 out of 10 foot regions. Furthermore, the normalized data suggest that the lateral forefoot in overweight adults was loaded more than the proportion of their extra weight, while the hallux and medial rearfoot were seemingly protected.
