Efeitos imediatos da MWM na dor, amplitude de movimento e funcionalidade, na osteoartrite da anca.

Introdução: A mobilização com movimento (MWM), segundo o Conceito Mulligan tem apresentado bons resultados na melhoria da dor, amplitude de movimento e funcionalidade em diversas disfunções. No entanto, existem poucos estudos sobre a articulação da anca e, até este momento, não foi avaliada a sua efetividade em indivíduos com osteoartrite da anca. Objectivo(s): Avaliar os efeitos imediatos da técnica de MWM na dor, na amplitude de movimento e na função física em indivíduos com osteoartrite da anca. Métodos: Foram incluídos 40 participantes com osteoartrite da anca, divididas de forma aleatória em dois grupos (experimental e placebo). Foram avaliadas as amplitudes de movimento de flexão e rotação medial da anca recorrendo ao goniómetro universal, a intensidade da dor através da Escala Numérica da Dor e a funcionalidade através de testes de função física, antes e imediatamente após a intervenção. Para o tratamento estatístico, foi utilizado um nível de significância de 0,05. Resultados: A aplicação de MWM resultou em diferenças significativas, com redução da dor na Escala Numérica da Dor (p=0,005), um aumento de amplitude de movimento de flexão (p=0,001) e de rotação medial (p=0,011), uma diminuição nos tempos dos testes de função física, o teste Timed “Up and Go” (p=0,037) e o teste “40m Self Placed Walk” (p=0,019), e um aumento nas repetições do teste ―30 seg Sit to Stand” (p=0,009), comparativamente ao grupo placebo. Conclusão: Os resultados sugerem que a técnica MWM parece produzir um efeito imediato significativo na diminuição da dor, aumento de amplitude articular e melhoria da função física em indivíduos com osteoartrite da anca. Este efeito foi maior para dor, para as amplitudes de movimento e para o teste de função física - ―30 seg Sit to Stand” quando se analisou a magnitude do efeito.

Immediate effects of hip mobilization with movement in patients with hip osteoarthritis: A randomised controlled trial

Background Mobilization with movement (MWM) has been shown to reduce pain, increase range of motion (ROM) and physical function in a range of different musculoskeletal disorders. Despite this evidence, there is a lack of studies evaluating the effects of MWM for hip osteoarthritis (OA). Objectives To determine the immediate effects of MWM on pain, ROM and functional performance in patients with hip OA. Design Randomized controlled trial with immediate follow-up. Method Forty consenting patients (mean age 78 ± 6 years; 54% female) satisfied the eligibility criteria. All participants completed the study. Two forms of MWM techniques (n = 20) or a simulated MWM (sham) (n = 20) were applied. Primary outcomes: pain recorded by numerical rating scale (NRS). Secondary outcomes: hip flexion and internal rotation ROM, and physical performance (timed up and go, sit to stand, and 40 m self placed walk test) were assessed before and after the intervention. Results For the MWM group, pain decreased by 2 points on the NRS, hip flexion increased by 12.2°, internal rotation by 4.4°, and functional tests were also improved with clinically relevant effects following the MWM. There were no significant changes in the sham group for any outcome variable. Conclusions Pain, hip flexion ROM and physical performance immediately improved after the application of MWM in elderly patients suffering hip OA. The observed immediate changes were of clinical relevance. Future studies are required to determine the long-term effects of this intervention.

How a cyber-physical system can efficiently obtain a snapshot of physical information even in the presence of sensor faults

We present a distributed algorithm for cyber-physical systems to obtain a snapshot of sensor data. The snapshot is an approximate representation of sensor data; it is an interpolation as a function of space coordinates. The new algorithm exploits a prioritized medium access control (MAC) protocol to efficiently transmit information of the sensor data. It scales to a very large number of sensors and it is able to operate in the presence of sensor faults.

A physical packing sequence algorithm for the container loading problem with static mechanical equilibrium conditions

The container loading problem (CLP) is a combinatorial optimization problem for the spatial arrangement of cargo inside containers so as to maximize the usage of space. The algorithms for this problem are of limited practical applicability if real-world constraints are not considered, one of the most important of which is deemed to be stability. This paper addresses static stability, as opposed to dynamic stability, looking at the stability of the cargo during container loading. This paper proposes two algorithms. The first is a static stability algorithm based on static mechanical equilibrium conditions that can be used as a stability evaluation function embedded in CLP algorithms (e.g. constructive heuristics, metaheuristics). The second proposed algorithm is a physical packing sequence algorithm that, given a container loading arrangement, generates the actual sequence by which each box is placed inside the container, considering static stability and loading operation efficiency constraints.

Physical therapy with drug treatment in bell palsy: a focused review

ABSTRACT: The physical therapy (PT) associated with standard drug treatment (SDT) in Bell palsy has never been investigated. Randomized controlled trials or quasirandomized controlled trials have compared facial PT (except treatments such as acupuncture and osteopathic) combined with SDT against a control group with SDT alone. Participants included those older than 15 yrs with a clinical diagnosis of Bell palsy, and the primary outcome measure was motor function recovery by the House-Brackmann scale. The methodologic quality of each study was also independently assessed by two reviewers using the PEDro scale. Four studies met the inclusion criteria. Three trials indicate that PT in association with SDT supports higher motor function recovery than SDT alone between 15 days and 1 yr of follow-up. On the other hand, one trial showed that electrical stimulation added to conventional PT with SDT did not influence treatment outcomes. The present review suggests that the current practice of Bell palsy treatment by PT associated with SDT seems to have a positive effect on grade and time recovery compared with SDT alone. However, there is very little quality evidence from randomized controlled trials, and such evidence is insufficient to decide whether combined treatment is beneficial in the management of Bell palsy.
