Vulvodynia Treated with Acupuncture or Electromyographic Biofeedback  [PDF]
Oroma B. Nwanodi, Melanie M. Tidman
Chinese Medicine (CM) , 2014, DOI: 10.4236/cm.2014.52007

First, second, and third line medical treatments of vulvodynia are of limited efficacy. Surgical resection, the fourth line treatment of vulvodynia, may have unforgiving sequela. Therefore, acupuncture and electromyographic (EMG) biofeedback could bridge between medical and surgical treatments of vulvodynia. Of note, EMG biofeedback is more frequently recommended in treatment algorithms for vulvodynia than is acupuncture. Trials of acupuncture for unprovoked vulvodynia demonstrate variable efficacy, whereas trials of EMG biofeedback for provoked vulvodynia demonstrate consistent efficacy. Trials of acupuncture for treatment of provoked and unprovoked vulvodynia using identical acupoints, a vulvar algesiometer for objective pain measurement, and standardized, validated, tools for outcome assessment are needed. Such trials may enable comparison of acupuncture to EMG biofeedback for the treatment of provoked and unprovoked vulvodynia. Similarly, trials of EMG biofeedback for treatment of unprovoked vulvodynia would increase the knowledge base of EMG biofeedback for treatment of vulvodynia.

Bruno Ferreira, Gabriel Pádua da Silva, Edson Donizetti Verri, Marisa Semprini, Selma Siéssere, Victor Rodrigues Nepomuceno, Camila Melo de Carvalho, Simone Cecilio Hallak Regalo, Emanuela Martins Nepomuceno
Open Journal of Stomatology (OJST) , 2012, DOI: 10.4236/ojst.2012.22016
Abstract: Objective: The purpose of this study was to investigate the presence of postural imbalances, which can interfere with the mandible position and affect the actions of the stomatognathic system. Materials and Methods: Forty men, aged between 23 to 29 years, were selected and divided into two groups: Group I comprised 20 healthy individuals with no clinical postural change diagnosis; Group II, 20 individuals who had ACL surgical, unilateral with patellar tendon graft, paired individual to individual (age and weight). All of them were submitted to an electromyography in different clinical conditions. In addition, a condylar biomechanical assessment was performed through videogrametry. Results: In electromyography and videogrametry, a normal standard biomechanical was observed for both groups, however, Group GII—Ligamentplasty presented an inhibition of the masticatory muscles and decreased joint kinesthetic. Conclusion: Based on the results obtained, it was concluded that after the reconstruction of the ACL, individuals presented changes in the stomatog-nathic system.

Patrícia Maria Monteiro, Simone Cecilio Hallak Regalo, Janete Cinira Bregagnolo, Maria Bernadete Sasso Stuani
Open Journal of Stomatology (OJST) , 2012, DOI: 10.4236/ojst.2012.24057
Abstract: The purpose of this study was to evaluate the electromyographic (EMG) activity of the masseter and temporalis muscles and the skeletal and dental behavior of children having slow maxillary expansion with a quadhelix appliance. The study sample consisted of 30 children (mean age = 7 years 4 months; 17 girls/13 boys) diagnosed with a unilateral posterior crossbite. Lateral cephalometric tracing and EMG analyses were carried out before orthodontic treatment (T1) and 1 month after removal of the appliance (T2). The EMG activity of the masseter and temporalis muscles was analyzed in two clinical situations: at muscular rest and during habitual chewing. Differences in the measurements were evaluated by using paired t tests. Maxillary expansion with the quadhelix appliance did not promote significant anteroposterior and vertical skeletal alterations. Among the cephalometric variables related to dental pattern, only 1-ANS-PNS values presented a significant increase at T2. At muscular rest, EMG analysis indicated a significant increase in the activity of the temporalis muscle. During habitual chewing, EMG activity decreased significantly for both evaluated muscles after removal of the quadhelix appliance. These alterations suggest an adaptation and reprogramming of the musculature to the new occlusal condition.
Conventional kinesiotherapy or Pilates mat exercises, what is more efficient for abdominal weakness? A feasibility study  [PDF]
Renan Lima Monteiro, Laio Braga de Oliveira, Luiz Armando Vidal Ramos, Mauricio Oliveira Magalh?es, Marília Maniglia de Resende, Bianca Callegari
Journal of Biomedical Science and Engineering (JBiSE) , 2013, DOI: 10.4236/jbise.2013.612146

The aim of this feasibility study was to contrast rectus abdominis (RA) muscle strength and electrical activity after two abdominal training protocols, conventional kinesiotherapy (CK) and Pilates mat exercises (PME). 13 participants were randomized to one of two groups: CK and PME, and were trained accordingly. The upper rectus abdominis (URA) and lower rectus abdominis (LRA) were independently examined and intra-group and inter-group comparison were done. Findings demonstrate a significant increase in RA strength after both protocols, relative to baseline. Significantly increased electrical activation was seen in the URA after CK. Training with PME, although as efficient as CK in strength improvement, produced decreased activation level of muscles. CK training induced an opposite result. The differences after training suggest that CK and PME training programmers may strength RA, but the neuromuscular activation strategies for that are not the same. PME can be incorporated into protocols to improve abdominals strength, and trunk stabilization.


Humane Non-Human Primate Model of Traumatic Spinal Cord Injury Utilizing Electromyography as a Measure of Impairment and Recovery  [PDF]
William A. Graham, Douglas L. Rosene, Susan Westmoreland, Andrew Miller, Ervin Sejdic, Shanker Nesathurai
Open Journal of Veterinary Medicine (OJVM) , 2013, DOI: 10.4236/ojvm.2013.31014

The overall goal of this project is to develop a humane non-human primate model of traumatic spinal cord injury that will facilitate the development and evaluation of therapeutic interventions. The model utilizes neurophysiological techniques to identify the location of the upper motor neuron axons that innervate the lower motor neurons that control tail musculature. This facilitates the placement of a selective lesion that partially disconnects the upper and lower motor neuron supply to the musculature of the tail. An implanted transmitter quantitatively measures electromyography data from the tail. The preliminary data indicates that this model is feasible. The subject was able to tolerate the implantation of the transmitter, without adverse effects. As well, there was no limb impairment, bowel dysfunction or bladder dysfunction. The histopathologic and electromyographic features of the selective experimental lesion were similar to human spinal cord injury.

Electromyographic study of shoulder and acromioclavicular joint muscles in women who underwent unilateral breast surgery of the types mastectomy and quadrantectomy  [PDF]
Antonia Dalla Pria Bankoff, Sonia Regina Jurado
Health (Health) , 2013, DOI: 10.4236/health.2013.511251
Abstract: We studied 20 women with mean age 57.7 years, being 9 with unilateral quadrantectomy surgery, 1 with surgery type bilateral quadrantectomy and 10 with unilateral mastectomy surgery. The average operative time was 9.8 (nine years and eight months). We studied using surface electromyography the mean deltoid, upper trape-zius and latissimus dorsi muscles in order to check the action potentials of these muscles when performing a sequence of movements of these joints. It was used for the study, an Acquisition Data System ADS1000 containing 12 channels. The electromyography (EMG) results expressed in RMS (Root Mean Square) were analyzed and compared between the surgical and nonsurgical side, among the three repetitions of the sequence of movements and between mastectomy and quadrantectomy for each muscle. For statistical analysis we used analysis of variance (ANOVA) with a double repetition factor (p < 0.05) for the EMG results. The results showed a significant difference (p < 0.05) between the surgical and non-surgical sides to the muscles studied. There was no significant difference between the three repetitions of sequential movements in electromyographic analysis to the muscles studied. There was no significant difference between the types of surgery (mastectomy and quadrantectomy) for the muscles studied.

Abstract: A valid non human primate model of traumatic spinal cord injury (TSCI) is essential to evaluate and develop new treatments. In previous experiments, it has been demonstrated that a transmitter can be implanted in the macaque fasicularis monkey that measures electromyographic data from the musculature of the tail. As well, previous experiments have demonstrated that selective lesions can be created in the lower thoracic spinal cord that does not cause limb weakness and/or bowel dysfunction. The histopathological features of these lesions appear similar to human TSCI. This paper describes a method by which the EMG data can be transformed into a quantitative metric of volitional limb movement (“Q”). This metric permits an objective assessment of injury, natural recovery as well as potential efficacy of candidate treatments.

Health (Health) , 2019, DOI: 10.4236/health.2019.114038
Abstract: The purpose of this study is to analyse the neuromuscular balance of the masticatory muscles and the influence on the athlete respiratory parameters induced by custom-made mouthguard. Twenty-six athletes (24 males and 2 females), of different disciplines, average age of 32.12 ± 12.05, were recruited. Each athlete received a custom-made mouthguard in the Ethylene-Vinyl-Acetate (EVA) thermoplastic material and using surface electromyography, the masseter muscles and the frontal beams of the temporal muscles were analysed, with and without mouthguard. The athletes were then subjected to a medical examination and cardiopulmonary test, in the condition with and without mouthguard. The use of mouthguard caused an improvement of all the electromyographic indexes analysed. In particular, GLOBAL INDEX (p = 0.0021), BAR (p = 0.0005), IMPACT (p = 0.0076) and ASIM (p = 0.0290) showed an enhancement statistically significant. For the cardiopulmonary test indexes as maximum oxygen uptake (VO2max), minute ventilation (VE), breathing reserve (BR), not statistically differences (p > 0.05) were reported. The custom-made mouthguard improved the neuromuscular balance of the masticatory muscles, symmetrizing the masseters and temporalis muscles work. It produced a better balancing distribution of occlusal loads both in the anterior-posterior direction and in the lateral direction and offered the possibility to produce more muscular work. Moreover, it did not constitute an impediment that can significantly disturb the athlete’s breathing during physical activity.
