The 2009-2014 Outlook for EEG/EMG/brain Function Monitoring Equipment in Asia & Oceana

The 2009-2014 Outlook for EEG/EMG/brain Function Monitoring Equipment in Asia & Oceana Review

This econometric study covers the outlook for eeg/emg/brain function monitoring equipment in Asia & Oceana. For each year reported, estimates are given for the latent demand, or potential industry earnings (P.I.E.), for the country in question (in millions of U.S. dollars), the percent share the country is of the region and of the globe. These comparative benchmarks allow the reader to quickly gauge a country vis-a-vis others. Using econometric models which project fundamental economic dynamics within each country and across countries, latent demand estimates are created. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study also does not consider short-term cyclicalities that might affect realized sales. The study, therefore, is strategic in nature, taking an aggregate and long-run view, irrespective of the players or products involved.

This study does not report actual sales data (which are simply unavailable, in a comparable or consistent manner in virtually all of the countries in Asia & Oceana). This study gives, however, my estimates for the latent demand, or the P.I.E. for eeg/emg/brain function monitoring equipment in Asia & Oceana. It also shows how the P.I.E. is divided across the national markets of Asia & Oceana. For each country, I also show my estimates of how the P.I.E. grows over time (positive or negative growth). In order to make these estimates, a multi-stage methodology was employed that is often taught in courses on international strategic planning at graduate schools of business.

Description:
Work related neck and shoulder disorders are a great problem for string musicians. A playing technique with more relaxed muscles and a greater variation in the muscle activity pattern, i.e., with shorter sequences at a varied number of amplitude levels as reflected by electromyography (EMG), might prevent pain. This study used EMG to study variations in the trapezius muscle activity pattern in 12 string musicians performing a piece of music at two playing sessions separated by a ten-week interval. Nine of the string musicians played violin, two viola and one cello. Exposure variation analysis and principal component analysis were used for analysis of the EMG. The trapezius muscle activity pattern was similar in the first and second playing sessions showing that each musician repeated his/her own muscular activity pattern. However, there was considerable variability in the muscle activity pattern between cello, violin and viola players and between individual violin players. Thus, this EMG method has the potential to identify variations and reproducibility of trapezius muscle activity in string musicians. This method may be used to analyse individual differences when performing a musical work task and to evaluate intervention studies. Relevance to industry: Intervention studies on muscle activity pattern which try to change the work technique need to be evaluated.

The 2009-2014 Outlook for EEG/EMG/brain Function Monitoring Equipment in Greater China

The 2009-2014 Outlook for EEG/EMG/brain Function Monitoring Equipment in Greater China Review

This econometric study covers the latent demand outlook for EEG/EMG/brain function monitoring equipment across the regions of Greater China, including provinces, autonomous regions (Guangxi, Nei Mongol, Ningxia, Xinjiang, Xizang - Tibet), municipalities (Beijing, Chongqing, Shanghai, and Tianjin), special administrative regions (Hong Kong and Macau), and Taiwan (all hereafter referred to as "regions"). Latent demand (in millions of U.S. dollars), or potential industry earnings (P.I.E.) estimates are given across some 1,100 cities in Greater China. For each major city in question, the percent share the city is of the region and of Greater China is reported. Each major city is defined as an area of "economic population", as opposed to the demographic population within a legal geographic boundary. For many cities, the economic population is much larger that the population within the city limits; this is especially true for the cities of the Western regions. For the coastal regions, cities which are close to other major cities or which represent, by themselves, a high percent of the regional population, actual city-level population is closer to the economic population (e.g. in Beijing). Based on this "economic" definition of population, comparative benchmarks allow the reader to quickly gauge a city's marketing and distribution value vis-a-vis others. This exercise is quite useful for persons setting up distribution centers or sales force strategies. Using econometric models which project fundamental economic dynamics within each region and city of influence, latent demand estimates are created for EEG/EMG/brain function monitoring equipment. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study also does not consider short-term cyclicalities that might affect realized sales. The study, therefore, is strategic in nature, taking an aggregate and

Evolution des variables respiratoires et EMG au cours de l'exercice: Étude chez des sujets sédentaires et des cyclistes (French Edition)

Evolution des variables respiratoires et EMG au cours de l'exercice: Étude chez des sujets sédentaires et des cyclistes (French Edition) Review

L'ensemble de ce travail de thèse s'attache à étudier les ajustements physiologiques qui surviennent au cours d'un travail musculaire mené jusqu'à l'épuisement. Nous avons focalisé nos travaux expérimentaux sur l'étude des relations entre l'activité électromyographique et les variables ventilatoires et respiratoires. Les résultats permettent de conclure, selon la population étudiée, à l'apparition d'un ou de deux seuils EMG durant une épreuve triangulaire de pédalage. Dans certains cas l'apparition de ces seuils est concomitante à l'apparition des seuils ventilatoires, ce qui permet de renforcer l'hypothèse selon laquelle l'activation des afférences musculaires métabosensibles serait à l'origine de l'apparition des seuils ventilatoires.

Description:
The purpose of the current study was to compare the repeatability of electromyographic linear envelopes (LE) of archery groups. Surface electromyography (EMG) signals of musculus flexor digitorum superficialis (MFDS) and extensor digitorum (MED) of 23 participants (seven skilled, six beginner archers and ten non-archers) were recorded during archery shooting. Two-second periods (clicker falls at first second) of 12 shots' EMG data were recorded, full-wave rectified and filtered (60ms moving-average filter) for each participant's drawing arm. Repeatability was investigated by using a statistical criterion, variance ratio (VR). Archers' performances were evaluated in terms of FITA scores. The results showed that FITA scores were significantly correlated to the VRs of MFDS and MED. EMG LEs were more repeatable among archers than non-archers. Therefore, we inferred that VRs of MFDS and MED might be important variables for (a) assessing shooting techniques, (b) evaluation of archers' progress, and (c) selection of talented archers.

Balancing Efficiencies and Tradeoffs in Epidemiological Field Studies: Evaluating EMG Exposure Assessment for Low Back Injury Risk Factors in Heavy Industry

Balancing Efficiencies and Tradeoffs in Epidemiological Field Studies: Evaluating EMG Exposure Assessment for Low Back Injury Risk Factors in Heavy Industry Review

In order to investigate work-related back injuries, researchers need efficient, accurate occupational exposure assessment methods suitable for large samples. This book examines critical decisions for measuring physical workload: How should exposure be measured? For what duration? Who should be measured, and how many times? To answer these questions, low-back electromyography (EMG) was collected during 138 full-shift field measurements over 30 different job titles at 50 different worksites in 5 heavy industries: forestry, transportation, wood products, construction, and warehousing. Observations and self-reports of working exposures were collected concurrently. Among the results emerges a theme of optimizing the choices for study design and sampling strategy. The ubiquitous constraints of budget and access to industrial populations require tradeoffs between using a highly accurate exposure assessment method on a few people or a less precise method on a larger number of people, between measurement duration and sample size, and between measuring many individuals or repeats within individuals. The results presented help inform risk guidelines, policy, and efforts to control exposure.

The 2009 Report on EEG/EMG/brain Function Monitoring Equipment: World Market Segmentation by City

The 2009 Report on EEG/EMG/brain Function Monitoring Equipment: World Market Segmentation by City Review

This report was created for global strategic planners who cannot be content with traditional methods of segmenting world markets. With the advent of a "borderless world", cities become a more important criteria in prioritizing markets, as opposed to regions, continents, or countries. This report covers the top 2000 cities in over 200 countries. It does so by reporting the estimated market size (in terms of latent demand) for each major city of the world. It then ranks these cities and reports them in terms of their size as a percent of the country where they are located, their geographic region (e.g. Africa, Asia, Europe, Middle East, North America, Latin America), and the total world market.

In performing various economic analyses for its clients, I have been occasionally asked to investigate the market potential for various products and services across cities. The purpose of the studies is to understand the density of demand within a country and the extent to which a city might be used as a point of distribution within its region. From an economic perspective, however, a city does not represent a population within rigid geographical boundaries. To an economist or strategic planner, a city represents an area of dominant influence over markets in adjacent areas. This influence varies from one industry to another, but also from one period of time to another.

In what follows, I summarize the economic potential for the world's major cities for "EEG/EMG/brain function monitoring equipment" for the year 2009. The goal of this report is to report my findings on the real economic potential, or what an economist calls the latent demand, represented by a city when defined as an area of dominant influence. The reader needs to realize that latent demand may or may not represent real sales.

Design and Analysis of Virtual Human Arm Driven by EMG Signal: Simulation with GUI design Review

The real human arm is a complex kinematics system. It works according to instructions calculated by a highly accurate method, and has a moving system working by deity manner. The design and simulation analysis of arm moving system model with 7-Degree of Freedom (DOF) are presented. The electromyography (EMG) signal is the activation signal for muscles in human arm and accordingly the arm will have a certain movement. The arm dynamic system in real environment simulation was implemented using the inverse kinematics problem (IKP) analytical solution. The computation time of this simulation is very fast and has the ability to include any real constrain. The finite recurrent back propagation neural network ( FRBP-NN ) is used with the simulated system for identification, classification, and human arm movements recognition with respect to a specific EMG signal. Virtual Reality Toolbox, which is interfaced with the Simulink MATLAB. Satisfactory results are obtained, which give the solution of the forward and inverse kinematic human arm and the usefulness of using FRBP-NN to recognize the movements of human arm.

Quantitative EMG analysis of core musculature activation patterns among elite college pitchers.

Quantitative EMG analysis of core musculature activation patterns among elite college pitchers. Review

Transfer of energy generated from lower extremity to upper extremity though optimal control of pelvis is the key to successful baseball pitching. Previous biomechanical studies have indicated pelvis and upper torso kinematic and kinetic differences between two types of pitches: fastball vs. change-up, but there is yet to be a comparison of muscle activations between the two pitches. It was the purpose of this study to quantitatively analyze core musculature of the lumbopelvic-hip complex during the fastball and change-up baseball pitches thrown by elite collegiate baseball pitchers. It was hypothesized that reproducible activation patterns would be observed between the two different pitches. Twelve male Division I collegiate baseball pitchers (20.1+/-1.5 years, 188.9+/-4.8 cm, and 87.2+/-7.5 kg) participated in the study. Surface electromyography data were collected on bilateral gluteus maximus and medius, hip adductors and external obliques while participants threw five fastballs and five change-ups for strikes. Paired sample t tests were conducted at defined event marks in attempt to identify possible differences between the two pitching styles. Reproducible activation patterns were identified. All of the analyzed muscles displayed high activations throughout the entire pitching cycle. The magnitude of activations in the muscles increased from the beginning to the end of pitching cycle. The non stride gluteus maximus and stride gluteus medius displayed higher muscle activities compared to their contralateral sides. Of all the examined muscles, the bilateral adductors displayed highest muscle activation throughout the entire movement. There were no significant differences between the muscle activations and the two pitching styles at the p≤0.01 level. In conclusion, the research successfully quantified muscle activation patterns in the core musculature among elite pitchers due to the sEMG data presented consistent trends.

Description:
Two experiments were conducted to investigate the functional relationship between the general somatic motor function and the oral motor function. In Experiment 1, we analyzed the relationship between the amount of masseter muscle (MSS) activity and the velocity of a ballistic, 'karate-do' arm thrusting movement (ThrMov). ThrMov velocity was measured from video images taken with a high-speed CCD camera at a frequency of 500Hz. EMGs of MSS and sternocleidomastoideus (SCM) muscles as well as other related muscles were recorded simultaneously with video images in 6 varsity 'karate-do' athletes. Pearson's correlation coefficients were calculated between EMG amplitude and movement velocity. EMG activity of MSS as well as the other muscles increased as a function of ThrMov velocity in all participants, as evidenced by highly significant (p<.01) correlation coefficients, ranging from .64 to .87 (mean: .75). MSS EMG activity attained during ThrMovs performed at maximum velocity ranged between 14.6% and 113.8% of this muscle's MVC (45.7+/-39.3% MVC, mean+/-SD). SCM was also strongly active and closely associated with MSS. Besides changes in amount of EMG activity, it was further found that R-MSS EMG onset progressively shifted to the earlier phase of the ThrMov as ThrMov velocity increased. EMG onset time of R-MSS as well as R- and L-SCMs was negatively correlated with ThrMov velocity; when performed at maximum velocity MSS activation preceded the start of ThrMov by more than 100ms, whereas MSS was recruited last at ~150ms after the start of ThrMov when performed at moderate speed (~50% of maximum). In Experiment 2, the effects of head movement relative to the trunk on R-MSS and SCMs EMG activity were tested in both gazing and sidelong glancing conditions. A much smaller head rotation relative to the trunk was necessary during the ThrMov in the sidelong glancing condition compared to the gazing condition. R-MSS EMG activity was affected significantly by the difference between these conditions and decreased by 5.2% MVC in the sidelong glancing condition compared to the gazing condition. In association with the change in requirement for head movement between those conditions, EMG balance between the bilateral SCMs changed substantially. Finally, marked muscle activity during ThrMov was found in the MSS that was not directly involved in performing this movement, indicating a form of 'remote facilitation'.
