Background and Objective: Altered Pattern of the Global Muscle system is presented in literature among individuals with sacroiliac Joint Dysfunctions. However, the pattern of changes in the Latissimus dorsi (LD) and gluteal maximus (GM) among sacroiliac joint dysfunctions (SIJD) is not reported. This study aimed to investigate the changes in the resting muscle thickness of the Latissimusdorsi and gluteal maximus in SIJD. Method: A total of 88 subjects (44 individuals with SIJD and 44 healthy individuals as matched control) was included in this study. The resting thickness of the Latissimusdorsi and gluteal maximus was measured using real time musculoskeletal ultrasonography and data was compared between the ipsilateral side and contra lateral side among subjects with SIJD as well as healthy subjects. Independent sample t test was used to analyze the data by using SPSS version-25. Results: The results showed that contralateral LD were reduced significantly among subjects with SIJD when compared with the other side and with control. It also showed that ipsilateral IO, TrA and GM were reduced significantly among subjects with SIJD when compared with the controls and with contralateral side. Conclusion: The reduced resting muscle thickness showed an altered motor pattern of Deep Muscles of local system and Gross muscles of global system among patients with sacroiliac joint dysfunction. doi: https://doi.org/10.12669/pjms.35.3.62 How to cite this:Bashir MS, Noor R, Hadian MR, Olyaei G.

BACKGROUND: The underlying morphology and behavior of abdominal muscles during breathing are still lacking in knowledge in healthy population. OBJECTIVE: To analyze the effects of three different types of breathing on the architectural characteristics of abdominal muscles. METHODS: Ninety-eight healthy subjects were measured to assess the effects of breathing on the abdominal muscles, subjects performed three different types of breathing and the muscular thickness was measured with ultrasound imaging, analyzing also the differences between sexes. RESULTS: During the three different types of breathing and in comparison with the resting state, an increase of the thickness has been reported in the transversus abdominis (p< 0.001; effect size = 2.44, very large) and internal oblique (p< 0.001; effect size = 1.04, moderate) in both sexes, but with a higher increase in men. External oblique and rectus abdominis increased their thickness through breathing only while the lips were with pursed (p< 0.05) with trivial effect sizes and only differences between sexes were found in rectus abdominis. CONCLUSIONS: All breathings activated the deepest abdominal muscles, but the most superficial were only activated with lips pursed. Moreover, men appeared to activate more the deepest abdominal muscles but also the rectus abdominis. Findings in this study support the use of different types of breathing depending on the muscle to be activated or the sex, helping health care professionals to address their interventions on the abdominal muscles with a more focused approach.

BackgroundThis cadaveric dose-finding study investigated the minimum effective volume of dye in 90% of cases (MEV90), required to stain the femoral, lateral femoral cutaneous and obturator nerves for ultrasound-guided suprainguinal fascia iliaca block (SIFIB).MethodsIn cadaveric specimens of the lower limb, the block needle was advanced, medial to the anterosuperior iliac spine, until its tip was positioned between the internal oblique and iliacus muscles underneath the fascia iliaca. The dye was injected inside the fascia iliaca compartment. Volume assignment was carried out using a biased coin design, whereby the volume of dye administered to each cadaveric specimen depended on the response of the previous one. In case of failure, the next one received a higher volume (defined as the previous volume with an increment of 2.5 mL). If the previous cadaveric specimen had a successful block, the next one was randomized to a lower volume (defined as the previous volume with a decrement of 2.5 mL), with a probability of b=0.11, or the same volume, with a probability of 1–b=0.89. Success was defined as the staining of the femoral, lateral femoral cutaneous, and obturator nerves on dissection.ResultsThirty-six cadavers (60 cadaveric specimens) were included in the study. Using isotonic regression and bootstrap CI, the MEV90 for ultrasound-guided SIFIB was estimated to be 62.5 mL (95% CI 60 to 65).ConclusionFor ultrasound-guided SIFIB, the MEV90 of dye required to stain the femoral, lateral femoral cutaneous and obturator nerves is 62.5 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in human subjects.

BACKGROUND: Recent clinical studies have revealed the advantages of using suspension devices. Although the supine, lateral, and forward leaning bridge exercises are low-intensity exercises with suspension devices, there is a lack of studies directly comparing exercise progression by measuring muscular activity and subjective difficulty. OBJECTIVE: To identify how the variations in the bridge exercise affects trunk muscle activity, the present study investigated changes in neuromuscular activation during low-intensity bridge exercises. We furthermore explored whether the height of the suspension point affects muscle activation and subjective difficulty. METHODS: Nineteen asymptomatic male participants were included. Three bridge exercise positions, supine bridge (SB), lateral bridge (LB), forward leaning (FL), and two exercise angles (15 and 30 degrees) were administered, thereby comparing six bridge exercise conditions with suspension devices. Surface electromyography and subjective difficulty data were collected. RESULTS: The rectus abdominis activity was significantly higher with the LB and FL exercises compared with the SB exercise (p< 0.05). The erector spinae muscle activity was significantly higher with the SB and LB exercises, compared with the FL exercise (p< 0.05). The LB exercise significantly increased the internal oblique muscle activity, compared with other exercise variations (p< 0.05). The inclination angle of the exercise only affected the internal oblique muscle and subjective difficulty, which were significantly higher at 30 degrees compared with 15 degrees (p< 0.05). CONCLUSIONS: Relatively higher inclination angle was not effective in overall activation of the trunk muscles; however, different bridge-type exercises could selectively activate the trunk muscles. The LB and SB exercises could be good options for stimulating the internal oblique abdominis, and the erector spinae muscle, while the FL exercise could minimize the erector spinae activity and activate the abdominal muscles.

Abstract Background and Purpose. Performing nontraditional abdominal exercises with devices such as abdominal straps, the Power Wheel, and the Ab Revolutionizer has been suggested as a way to activate abdominal and extraneous (nonabdominal) musculature as effectively as more traditional abdominal exercises, such as the crunch and bent-knee sit-up. The purpose of this study was to test the effectiveness of traditional and nontraditional abdominal exercises in activating abdominal and extraneous musculature. Subjects. Twenty-one men and women who were healthy and between 23 and 43 years of age were recruited for this study. Methods. Surface electromyography (EMG) was used to assess muscle activity from the upper and lower rectus abdominis, external and internal oblique, rectus femoris, latissimus dorsi, and lumbar paraspinal muscles while each exercise was performed. The EMG data were normalized to maximum voluntary muscle contractions. Differences in muscle activity were assessed by a 1-way, repeated-measures analysis of variance. Results. Upper and lower rectus abdominis, internal oblique, and latissimus dorsi muscle EMG activity were highest for the Power Wheel (pike, knee-up, and roll-out), hanging knee-up with straps, and reverse crunch inclined 30 degrees. External oblique muscle EMG activity was highest for the Power Wheel (pike, knee-up, and roll-out) and hanging knee-up with straps. Rectus femoris muscle EMG activity was highest for the Power Wheel (pike and knee-up), reverse crunch inclined 30 degrees, and bent-knee sit-up. Lumbar paraspinal muscle EMG activity was low and similar among exercises. Discussion and Conclusion. The Power Wheel (pike, knee-up, and roll-out), hanging knee-up with straps, and reverse crunch inclined 30 degrees not only were the most effective exercises in activating abdominal musculature but also were the most effective in activating extraneous musculature. The relatively high rectus femoris muscle activity obtained with the Power Wheel (pike and knee-up), reverse crunch inclined 30 degrees, and bent-knee sit-up may be problematic for some people with low back problems.

Introdução: A correta ativação da musculatura estabilizadora do tronco é essencial em diversas situações, inclusive prevenção e tratamento de lombalgias. A ativação adequada desses músculos é um princípio do Método Pilates, porém nem todos os efeitos das variações dos exercícios estão descritos da literatura. Objetivo: comparar a atividade elétrica de músculos do power house (reto abdominal, oblíquo externo, oblíquo interno/transverso abdominal e multífido) durante a execução do exercício Leg Circles no aparelho Cadillac com mola alta e com mola baixa. Métodos: Foram selecionadas 10 instrutoras de Pilates, 30 anos (±5), 58 Kg (±7), estatura 163 cm (±7) que foram submetidas a testes de contrações isométricas voluntárias máximas, e logo após, à realização do Leg Circles no Cadillac com a mola alta e baixa. Foi coletada a atividade elétrica dos músculos reto abdominal, oblíquo interno/transverso abdominal, oblíquo externo e multífido. Resultados: A ativação do oblíquo interno foi maior na mola alta (p=0,002), assim como a ativação do multífido (p=0,042). Já o oblíquo externo foi mais ativado na mola baixa (p=0,001). O reto abdominal não variou sua ativação (p=0,375). Conclusão: A mola alta pode ser acatada como a posição mais adequada para ativar a musculatura profunda do tronco, visto que nesta situação houve maior ativação do multífido e do oblíquo interno/transverso abdominal, somados à menor ativação do oblíquo externo e a baixa ativação no reto abdominal encontrados na situação com mola alta. ABSTRACT. Leg circles on Cadillac: effect of different spring positions on the activation of stabilizers in the trunk. Background: The correct activation of the trunk stabilizing muscles is essential in several situations, including prevention and treatment of low back pain. Proper activation of these muscles is a principle of the Pilates Method, but not all the effects of exercise variations are described in the literature. Objective: compare the electric activity of power house muscles (rectus abdominis, external oblique, internal oblique/transverse abdominal and multifidus) during the execution of the Leg Circles exercise with high spring and low spring in Cadillac apparatus. Methods: Ten Pilates instructors were selected, with 30 years (±5), 58 kg (±7), 163 cm (±7) who underwent maximum voluntary isometric contraction tests before the execution of the Leg Circles on the Cadillac, with high and low spring. The electrical activity of the rectus abdominis, internal oblique/transverso abdominal, external oblique and multifidus muscles was collected. Results: The internal oblique (p=0,002) and the multifidus (p=0,042) activations were greater on the high spring. However, the external oblique showed a higher activation on the lower spring (p = 0.001). The abdominal rectus did not change its activation = 0.375). Conclusion: The high spring can be considered as the most suitable position to ac-tivate the deep musculature of the trunk, since the greater activation of the multifidus and of the internal oblique/transverse abdominal, together with the lower activation of the external oblique and the low acti-vation in the rectus abdominus found in the high spring situation.
