Method Analysis

The aim of the study was to analyze the relationship between the angle of spinal curvature and surface electromyography (SEMG) amplitude of the erector spinae in young school-children. A total of 251 children aged 7–8 participated in the study. The analysis involved 103 (41%) children with scoliosis, 141 (56.17%) with scoliotic posture, and seven (3.0%) with normal posture. Body posture was evaluated using the Diers formetric III 4D optoelectronic method. Analysis of SEMG amplitude of the erector spinae was performed with the Noraxon TeleMyo DTS apparatus. A significant correlation was found between the angle of spinal curvature and the SEMG amplitude of the erector spinae. The most important and statistically significant predictor of the SEMG amplitude and scoliosis angle in the scoliosis group was the standing position, chest segment, right side. The largest generalized SEMG amplitude of the erector spinae occurred in both boys and girls with scoliosis. Impaired balance of muscle tension in the erector spinae can trigger a set of changes that create a clinical and anatomopathological image of spinal curvature.

Erector Spinae Muscle

The objective of the present research was to assess the relationship between muscle tone of the erector spinae and the concave and convex sides of spinal curvature in low-grade scoliosis found among children. The study included 251 children, aged 7–8. Examination of the spine and body posture was carried out using the Diers Formetric III 4D optoelectronic method. Surface electromyography (sEMG) was used to assess erector spinae muscle tone. The trial was carried out using the 14-channel Noraxon TeleMyo DTS apparatus. The highest generalised tone (sEMG amplitude) of the erector spinae occurred in the case of scoliosis. The higher the angle of curvature, the greater the erector spinae muscle tone. Regardless of the position adopted during examination of the thoracic spine, greater erector spinae tone (sEMG amplitude) was exhibited on the convex side of the spinal curvature. However, in the area of the lumbar spine, greater tone (sEMG amplitude) of the erector spinae occurred on the curvature’s concave side. The exception was the test performed in a standing position, during which greater muscle tone was noted on the side of the convex curvature. In therapeutic practice, within the thoracic section, too tense erector spinae muscles should be stretched on the convex side of the scoliosis, while in the lumbar region, this should be performed on the concave side. However, each case of scoliosis requires individually tailored treatment. The current research has applicative value and does fill a research gap with regard to erector spinae muscle tone in young children experiencing low-grade scoliosis. The development of scoliosis is associated with asymmetry and an increase in erector spinae tone. The uneven distribution of its tone, occurring on both sides of the spine and in its various segments, causes destabilisation and its abnormal progression.

Gastrocnemius Muscles

In metal stamping industry, almost all jobs are practically to be performed in standing position. Standing in a long period of time can lead to muscle fatigue. The objective of this study was to determine time-to-fatigue in the erector spinae, tibialis anterior, and gastrocnemius muscles of twenty production workers in a metal stamping company. The muscles activity was concurrently measured using surface electromyography (sEMG) during beginning, mid, and end of working sessions. Results of study found that gastrocnemius muscle fatigued earlier during all working sessions. In addition, working at the end of working session showed earlier fatigue than the beginning and mid of work days. The study concluded that standing in a long period of time is a cause to muscle fatigue experienced by the production workers.

Gomez and her colleagues have presented a helpful study of the relationship of the chaplains in her health system to physicians which highlights several barriers to a well-integrated relationship and thus to more optimal patient care. We have seen these same barriers as we have consulted with health systems nationally and have also identified many best practices that mediate or even eliminate many of these barriers. This commentary describes some of what we have seen as chaplain-generated causes of those barriers and effective strategies that have been employed to overcome them. We also provide some resources for chaplains who wish to institute some of these best practices themselves.

The Relationship

In this paper, we explore, name, and unpack the possibilities that printmaking, as an art form, holds in visual narrative inquiry. We also explore the relationship between visual narrative inquiry and narrative inquiry, a relational qualitative research methodology that attends to experiences. Drawing on two different ongoing narrative inquiry studies, where we engage with either trans young adults or refugee families from Syria with pre-school children, we explore how printmaking practices facilitate processes of inquiry. The etymology of the word “frame” helps us understand framing as a process that is future oriented and reflects a sense of doing, making, or preforming. In this way, framing allows us to see otherwise, to respond to and with participants, and to engage with experiences in ways that open new possibilities of inquiry.

The Relationship

Abstract Background Physical inactivity due to cachexia and muscle wasting is well recognized as a sign of poor prognosis in chronic obstructive pulmonary disease (COPD). However, there have been no reports on the relationship between trunk muscle measurements and energy expenditure parameters, such as the total energy expenditure (TEE) and physical activity level (PAL), in COPD. In this study, we investigated the associations of computed tomography (CT)-derived muscle area and density measurements with clinical parameters, including TEE and PAL, in patients with or at risk for COPD, and examined whether these muscle measurements serve as an indicator of TEE and PAL. Methods The study population consisted of 36 male patients with (n = 28, stage 1–4) and at risk for (n = 8) COPD aged over 50 years. TEE was measured by the doubly labeled water method, and PAL was calculated as the TEE/basal metabolic rate estimated by the indirect method. The cross-sectional areas and densities of the pectoralis muscles, rectus abdominis muscles, and erector spinae muscles were measured. We evaluated the relationship between these muscle measurements and clinical outcomes, including body composition, lung function, muscle strength, TEE, and PAL. Results All the muscle areas were significantly associated with TEE, severity of emphysema, and body composition indices such as body mass index, fat-free mass, and trunk muscle mass. All trunk muscle densities were correlated with PAL. The product of the rectus abdominis muscle area and density showed the highest association with TEE (r = 0.732) and PAL (r = 0.578). Several trunk muscle measurements showed significant correlations with maximal inspiratory and expiratory pressures, indicating their roles in respiration. Conclusions CT-derived measurements for trunk muscles are helpful in evaluating physical status and function in patients with or at risk for COPD. Particularly, trunk muscle evaluation may be a useful marker reflecting TEE and PAL.
