Thermographic evaluation was performed on 11 adult volunteers with myofascial trigger points and on 11 asymptomatic controls. Infrared thermography was used to obtain a series of images to compare ...the sensory referral areas of myofascial trigger points with their thermal referral patterns. A series of images was then taken at, and distal to, the sensory referral area of each trigger point during quantitative compression of the trigger point, and dynamic temperature changes were monitored. Asymmetric thermal patterns were observed at all trigger points in the sensory referral area and distal to the referred area before compression. The thermal referral areas showed a reduction in temperature from precompression levels during compression. When similar but asymptomatic areas were compressed, no significant changes in temperature were noted at distal sites.
Os pontos gatilhos miofasciais (PGMs) são manifestações comumente encontradas na prática clínica e estão relacionados à alteração de tônus e à síndrome dolorosa miofascial (SDM). OBJETIVO: Avaliar a ...capacidade da EMG de superfície e detectar alterações da atividade neuromuscular no PGM, em situações de repouso e de contração isométrica voluntária máxima. MÉTODO: Participaram do estudo 56 indivíduos distribuídos em dois grupos: grupo Saudável com 28 indivíduos, que necessariamente não possuíam PGM, e o grupo Dor, constituído de 28 indivíduos que possuíam necessariamente PGM no músculo escolhido. O grupo Dor apresentava indivíduos com PGM latente e ativo, e com e sem fenômenos autonômicos (FA). RESULTADOS: O sinal EMG da porção muscular com PGM mostrou-se significativamente maior quando comparado com a porção muscular sadia do grupo Dor, e do grupo Saudável durante o repouso (26,56 ± 44,54, 5,39 ± 6,29 e 1,56 ± 0,76, respectivamente, p = 0,0001). Os indivíduos com PGM ativo obtiveram maior intensidade do sinal EMG do que aqueles que apresentaram PGM latente (17,85 ± 30,25 versus 3,74 ± 1,52, p = 0,04). Além disso, os indivíduos que apresentaram fenômenos autonômicos tiveram maior intensidade do sinal EMG do que aqueles que não os apresentaram (16,78 ± 28,44 versus 3,51 ± 3,65), na condição de repouso. CONLUSÃO: A EMG de superfície é capaz de mensurar a atividade do PGM, principalmente na condição de repouso.There are examples of common clinical conditions that clinical signals are related to alterations in muscle tone, including myofascial pain syndrome. OBJECTIVE: to discuss the application of surface EMG to detect effect of miofascial trigger point (MTP) on neuromuscular activity at rest and maximum voluntary contraction of the trapezoid muscle. METHODS: Fifty-six subjects participated in the study and were divided into two groups: Healthy group (n = 28), with subjects who necessarily did not present MTP, and PAIN group (n = 28), with subjects who necessarily had MTP. RESULTS: The EMG signal was significantly higher in the muscle portion containing MTP than in the healthy muscle portion in PAIN group and than Healthy group (26,56 ± 44,54, 5,39 ± 6,29 and 1,56 ± 0,76, respectively, p = 0,0001) during rest. In addition, a higher intensity of the EMG signal was observed in subjects with active MTP than in latent MTP (17,85 ± 30,25 versus 3,74 ± 1,52, p = 0,04. Besides, the subjects who presented autonomic phenomena had higher EMG signal than those who had no autonomic phenomena (16,78 ± 28,44 versus 3,51 ± 3,65. CONCLUSION: The surface EMG is reliable to measure the muscular activity of the MTP, mainly at rest condition.
Traditional Chinese veterinary medicine (TCVM) has been practiced for thousands of years. TCVM focuses on keeping the mind and body in balance as imbalance leads to illness and disease. TCVM is ...categorized into five branches that include diet and food, exercise ‐Qi‐gong, Tui‐Na, acupuncture, and herbal medicine. A diagnosis in TCVM is reached by differentiating patterns — those of the patient's constitution and of disease or imbalance. The diagnostic systems used include yin‐yang, eight principles, zang‐fu organs, four levels, six stages, san jiao, and pathogenic factors. In both the human and veterinary field of study, myofascial trigger points (MTrPs) cause pain. Palpation after clinical evaluation is currently the only method used in veterinary medicine to definitively diagnose MTrPs. While it is important for veterinary technicians to understand the principles and practices of veterinary chiropractic, it is not appropriate for technicians to perform animal chiropractic adjustments.
Electrical activity in the nerve axon or muscle fibre according to the “all or nothing” type, when the membrane potential polarity ceases or is restored abruptly.
An infectious disease due to the HIV retrovirus (human immunodeficiency virus). Two types of virus exist: HIV-1 and HIV-2. Both cause serious immune system defects. The present pandemics are ...predominantly due to HIV-1, which is more pathogenic. It is transmitted by homosexual or heterosexual intercourse, transfusion of infected blood and its derivates, IV drug administrations using infected needles, organ transplant from an infected donor, or from an infected mother during labour or breast-feeding.
Die Untersuchung und Behandlung der Muskulatur sind wichtige Bestandteile der Manuellen Medizin. In der ÄMM wird sie in den Weiterbildungskursen und in speziellen Triggerpunkt- und Muskelkursen ...gelehrt. Bei bestimmten Muskeln überwiegen posturale Muskelfasern (Typ I), diese Muskeln neigen zur Verspannung/Verkürzung. Über das spinale Segment wird der phasische Antagonist (mit Fasern vom Typ II) eines verspannten Muskels gehemmt. Dieser wird dadurch schwach.In standardisierten Tests kann man die verminderte Verlängerbarkeit von Muskeln testen, ebenso kann die Abschwächung standardisiert getestet werden. Dazu dienen u. a. die Stereotyptests. Für die verminderte Verlängerbarkeit von Muskeln gibt es Techniken zur Relaxation oder Dehnung, für die Wiedereinbindung abgeschwächter Muskeln in den Bewegungsablauf dienen uns neurophysiologische krankengymnastische Techniken. Bei der Behandlung geht Verspannungs-/Verkürzungsbehandlung vor Behandlung der Abschwächung.
