Syfte Tidigare forskning har visat att Tai Chi träning förbättrar balansen hos äldre. Syftet med denna studie var att undersöka om barns balans påverkades av träning som utfördes i ett långsamt tempo liknande Tai Chi träning. Studien syftade också till att utreda om det förelåg någon skillnad i balans mellan pojkar och flickor och om något av könen tog till sig träningen bättre. Studien syftade även till att undersöka hur balansen påverkades då barnen utförde olika kognitiva uppgifter. Metod Studien fullföljdes av 41 barn i åldern 9-10 år. En interventionsgrupp, 19 barn tränade Tai Chi liknande rörelser dagligen under åtta veckor och denna jämfördes med en kontrollgrupp, 22 barn som inte fick denna träning. Balansövningar utfördes på en kraftplatta samt på en metallprofil. Från övningarna på kraftplattan mättes standardavvikelse och amplitud av tryckcentrums mediolaterala och anterioposteriora förflyttning. Från övningarna på metallprofilen mättes antalet nedtramp. Resultat Många parametrar mättes men endast en uppvisade en signifikant träningseffekt. Pojkarna minskade standardavvikelsen på tryckcentrums mediolaterala förflyttning vid stående med öppna ögon. Studien uppmätte vissa skillnader i balans mellan pojkar och flickor. Mätningar av tryckcentrums förflyttning då barnen utförde olika uppgifter uppmätte en signifikant skillnad vid stående med öppna ögon jämfört med stående då ögonen var stängda (med eller utan utförande av en samtida kognitiv uppgift). Övningarna på metallskenan förbättrades lika mycket i tränings- som kontrollgrupp. Slutsats Studien ger indikationer att träningsformen i viss utsträckning var effektiv då daglig träning under åtta veckor gav signifikant förbättring i en av de testade parametrarna. Dessa fynd är i linje med de fåtal studier som finns på träning av balans hos barn. / Aim. Previous studies have shown that Tai Chi exercises improve postural control in elderly people. The primary aim of this study was to investigate if similar Thai Chi like training affects postural control in children. Secondary aims of the study was 1) to investigate if any such effects from training differs between boys and girls and 2) to investigate whether performing a cognitive task during balance testing had any effect on postural control in these children. Method. In the balance tests, different tasks were performed on a force plate and on a metal profile. From the tasks performed on the force plate, the standard deviations and amplitudes of the mediolateral and anterioposterior displacements of center of pressure were measured. From the tasks performed on the metal profile, the number of clampdowns were counted. The study was conducted over an eight week period with 41 children in the ages 9-10 years old. The children were divided into two groups; children in the training group (n=19) who participated in Tai Chi like training every day, and children in the control group (n=22) who did not participate in this training. Results. The study also showed some differences in postural control between boys and girls. When comparing the displacement in center of pressure between different two-legged tasks performed on the force plate, significantly less displacement was found in the task involving standing with open eyes compared to all tasks involving standing with closed eyes (with or without a concurrent cognitive task). The number of clampdowns from the metal profile were reduced after the training period, to a similar extent in the control and the training groups. Several different aspects of the postural control were measured in the study. Only one of these improved significantly with training. Boys in the intervention group showed a decrease in the standard deviation of the mediolateral displacement of the center of pressure when standing with open eyes. Conclusion. These results are also consistent with similar studies on postural control among children. This study indicates that slow motion training, similar to Tai Chi, has a small but positive effect on postural control, for boys 9-10 year old, when conducted every day over an eight week period, as one of the tested parameters shows an improvement.

Tai Chi Chuan is a safe alternative for those who wish to improve balance and physical wellbeing. It is a popular form of exercise that is supported by a growing body of research aimed towards improving the health of a sedentary elderly population. The purpose of this study was to examine the biomechanical features of the lower extremity during performance of two Tai Chi movements, the “Repulse Monkey (RM)” and “Wave-hands in clouds (WHIC).” The study’s parameters included quantitative measures of the temporospatial, kinematic, and kinetic characteristics of the lower extremities. A group of experienced male Tai Chi practitioners (n = 15) between the ages of 65 to 75, performed “Repulse Monkey (RM)”, “Wave-hand in Cloud (WHIC)”, and forward walking. Three-dimensional (3-D) kinematic and kinetic data was collected using VICON motion analysis system with 10 infrared cameras and 4 force plates. The following variables were examined: stride width, step length, step width, single- and double-support times, centre of mass (COM) displacement, peak joint angles, range of motion, peak joint moments, time to peak moment, and ground reaction force (GRF). The differences in the measurements of the two Tai Chi movements were compared with walking using two-way ANOVA. The study’s results showed that the two Tai Chi movements elicit gentle and fluid changes to position of the upper body mass and the joints in the lower extremity. In terms of joint kinematics, the knee remained flexed throughout RM and WHIC. Unlike walking, RM had larger abduction and adduction angles at the knee joints and large plantar- and dorsiflexion ROM at the ankle. Reduced posterior, mediolateral, and vertical GRF were seen; the loading joints at the ankle and hip were gentle and smaller than walking. Varus/valgus moments were notably larger at the knee joint during RM and eversion moment was larger at the ankle joint during WHIC movement. A large, but slow loading rate at the knee joint has implication towards the viscoelastic properties of the knee. A better understanding of RM and WHIC would facilitate the improvement of balance, physical capacity, and joint flexibility for the elders.

Based on ethnographic research in Ruam Chai, a large and remote village in northern Thailand, this dissertation seeks to examine the emergence of ethnic identity and nationalistic consciousness of the Tai people within the context of Thai nation-building, state development, and the history of the area in the 20th century. The Tai—generally known as the Shan—are the predominant residents of this multi-ethnic frontier community, once occupied by the notorious opium warlord, Khun Sa, prior to absolute control and administration by the Thai state in 1982. These people migrated from various areas of Myanmar’s Shan State over different periods of time, for a variety of reasons. Due to their illegal immigration, the Thai state classifies them into different non-citizenship statuses according to their migration background as well as survey and registration periods. As a result of recent revisions of the Thai Nationality Act, the documented Thailand-born offspring of these displaced Tai, whose parents’ statuses fall into certain non-Thai categories, meet the nominal requirements for becoming naturalised. Within the theoretical framework of constructivist approach and the notion of ethnic dynamism and nationalistic sentiments as a cultural practice in borderlands, this dissertation suggests the investigation of the Tai ethno-nationalism through three interconnected levels of analysis: village or community, national, and transborder. On the village level, while the Tai acknowledge their ethnic diversity and have a logical, conventional system of identification among themselves; they maintain ethnic boundaries amid interactions with village members of other ethnic origins, and (re)construct identities in response to both internal and external forces. On the national level, a nation-building process has induced a stronger sense of “being Thai” to both Thailand-born Tai children and pre-existing generations of Tai. This process emphasises ethnic homogeneity—through the employment of the Thainess concept—and exclusion of the Non-Thai from the Thai, where categorically ineligible Tai are driven to embrace outlawed conduct to secure Thai citizenship. On the transborder level, movements back and forth as well as relationships across various international borders have played a vital role in constructing Tai identity and imagining the nation of the Tai people, both in Ruam Chai and beyond.

Bakgrund: Typ 2-diabetes är en sjukdom som i ökar Sverige. En viktig uppgift som sjuksköterskan har är att motivera patienter med typ 2-diabetes till livsstilsförändringar vad gäller kost, motion, rökavvänjning och stresshantering och får dessutom skriva ut fysisk aktivitet på recept. Intresset för komplementär och alternativ medicin (KAM) ökar i västvärlden. Syfte: Syftet med föreliggande studie var att belysa möjliga effekter av yoga, tai chi och qigong på ett urval objektiva och subjektiva parametrar hos vuxna personer med eller med risk för typ 2-diabetes. Metod: Litteraturöversikt, baserad på 17 vetenskapliga studier. En innehållsanalys gjordes för att sammanställa materialet och studera likheter och skillnader. Resultat: Yoga, tai chi och qigong hade i vissa fall positiva effekter på parametrarna blodglykos, lipider, kroppsmått, blodtryck, fysiskt och psykiskt välbefinnande, vitalitet, stresshantering, och motivation för egenvård. Diskussion: Att ställa de olika studiernas resultat mot varandra var inte möjligt på grund av att de skiljde sig från varandra vad gäller urval, design och intervention. Då dessa mind-body-terapier ej är vetenskapligt bevisade får de inte rekommenderas av sjuksköterskor. Dock åligger det sjuksköterskor enligt Socialstyrelsens kompetensbeskrivning att inspirera till dialog om införande av ny kunskap. Slutsats: Innan rekommendationer kan ges bör effekten av de olika teknikerna undersökas närmare.

We have previously used a two-dimensional fluorescence difference gel electrophoresis protein expression with matrix-assisted laser desorption ionization of mass spectrometry to identify the serum proteomic profiles before and after the Tai Chi exercise in normal adults (Yang & Chang, et al. Clin Chem 56:127, 2010). However, the high abundant serum proteins in seyal samples might interfere the discovery of low abundance proteins in two-dimensional electrophoresis, but these low abundant proteins may play an important role on human physiology. Therefore, we looked for another way to resolve this complex issue. After multiple attempts, we chose a commercial affinity column to exclude 14 kinds of high-abundance proteins before analyses of serum proteomic displays. This column could be fit into a fast liquid chromatography separation of purified proteins and eluted for low abundant proteins. The low abundant proteins were first expressed by one-dimensional gel electrophoresis of proteins followed by a series of gel cut down for in-gel digestion by trypsin and subject to nano-liquid chromatography with electrospray ionization tandem mass spectrometry analysis (nano-LC ESI MS/MS ). The results obtained by software analysis were subject to its functional pathways analysis. We analysed 3 comparisons of the protein displays including differences between normal adults before and after exercise, differences of normal adults and diabetic patients before and after exercise. Experiments were next performed to validate the most significant difference of proteins between each category by enzyme-linked immunoassay. Results showed that dipeptidyl peptidase 4 (DPP4) and neutrophil gelatinase-associated lipocalin (NGAL) proteins were significantly higher in diabetic patients than in normal adults ( P values were 0.011 and less than 0.001), while the prolactin-inducible protein (PIP) was higher in normal adults than in diabetic patients after exercise (P value of 0.042). To our knowledge, decrease of DPP4 in type 2 diabetes has been shown to reduce blood sugar and improve the immunity; and NGAL has been confirmed to be an indicator for early diagnosis of acute kidney injury. Therefore, we have identified certain functional proteomic markers in normal and diabetic patients after Tai Chi exercise. This study model with exclusion of high-abundance serum proteins is a useful mode for identifying immune and metabolic marker with and without.
