Contrasting

Order By: Relevance

“…One explanation for this contrast may be different baseline characteristics of participants and the presentation of non-normalized data. A correlation has been found to exist between the muscle thickness and anthropometric data, so muscle thickness data are recommended to be normalized in future studies [23]. Accordingly, normalized thickness changes were analyzed in this study to address this issue.…”

This study aimed to investigate the altered ultrasonographic activity of abdominal muscles during breathing in males with and without NSCLBP. Design: cross-sectional study Methods: Twenty males with NSCLBP and 20 males without NSCLBP were recruited. Muscle thickness change was measured by ultrasonography during breathing in end-inspiration and endexpiration phases for Transverse Abdominis (TrA), Internal Oblique (IO), External Oblique (EO), and Rectus Abdominis (RA) muscles. The data were normalized to the end-inspiration thickness.The independent t-test was run to analyze data at a confidence level of 95% (p<0.05). Results:The participants with NSCLBP had thicker IO muscle in the end-inspiration (P=0.030) and end-expiration (p=0.017) phases and greater RA (p=0.006) and smaller EO (p=0.003) normalized thickness changes during breathing. Conclusion:The normalized thickness changes during breathing differed between participants with and without NSCLBP. Reduced EO and increased RA activity may predispose the spine to further injuries, therefore normalizing the breathing pattern should be considered in the management of people with NSCLBP.

“…As muscle morphology is in uenced by age, sex, physical activity levels and body composition, (21,22) adjusting for such anthropometric factors is critical when assessing the relation between LM morphology and lumbar pathology. Body mass index (BMI) is most frequently used to adjust for inter-subject variability; however, it remains a poor indicator of body composition, especially in athletic populations.…”

“…Body mass index (BMI) is most frequently used to adjust for inter-subject variability; however, it remains a poor indicator of body composition, especially in athletic populations. (22) While dual energy X-ray absorptiometry is the gold standard to assess body composition, it is costly and not readily accessible. Multi-frequency Bioimpedance Analysis (MF-BIA) is an accurate, quick, noninvasive, portable and affordable alternative.…”

Background Degenerative structural changes and functional deficits of the lumbar multifidus (LM) muscle were observed in athletes with low back pain. While spinal injuries are common in circus artists, there is no information on LM characteristics in this population. The aims of this study were to investigate LM morphology and function and explore the relationship between LM characteristics and low back pain in student circus artists. Methods Thirty-one college circus students were recruited. Participants completed an online survey to acquire demographic data and low back pain history. Body composition was measured using multi-frequency bio-impedance analysis. Ultrasound examinations at the 5th lumbar vertebrae in prone and standing positions were performed to assess LM cross-sectional area, echo-intensity, thickness. Independent and dependent t-test assessed the difference between sex and side, respectively. The relationships between measures were assessed with Person’s correlations. The LM characteristics’ difference between artists with and without low back pain was assessed with Analysis of covariance using lean body mass, height and % body fat as covariates. Results Males had significantly larger LM cross-sectional area, lower echo-intensity and greater thickness change from rest to contracted than females. LM cross-sectional area asymmetry in prone was greater in artists reporting low back pain in the previous 4-weeks (p = 0.029) and 3-months (p = 0.009). LM measures were correlated with lean body mass, height, and weight (r = 0.40–0.77, p ≤ 0.05). Conclusion This study provided novel insights into LM characteristics in circus artists. Greater LM asymmetry was observed in artists with a history of low back pain. In accordance with previous studies in athletes, LM morphology and function were highly correlated with body composition measurements.

While spinal injuries are common in circus artists, there is no information on LM characteristics in this population. The aims of this study were to investigate LM morphology and function and explore the relationship between LM characteristics and low back pain in male and female circus artists. Methods 31 college circus students were recruited. Participants completed an online survey to acquire demographic data and low back pain history. Body composition was measured using multi-frequency bio-impedance analysis. Ultrasound examinations at the fifth lumbar vertebrae in prone and standing positions were performed to assess LM cross-sectional area, echo-intensity, thickness. Independent and dependent t-test assessed the difference between sex and side, respectively. The relationships between measures were assessed with Pearson’s correlations. The LM characteristics’ difference between artists with and without low back pain (group binary variable) was assessed with Analysis of covariance using lean body mass, height and % body fat as continuous covariates. Results Males had significantly larger LM cross-sectional area, lower echo-intensity and greater thickness change from rest to contracted than females. LM cross-sectional area asymmetry in prone was greater in artists reporting low back pain in the previous 4-weeks (p = 0.029) and 3-months (p = 0.009).
