“…Further research must be conducted to determine the physiological changes occurring in the postural control system when alterations in COP variables are detected. Similar findings were observed in our previous study [50] in which fatigue was induced by repetitive dynamic contractions of trunk extensors and clinical scales of balance viz.…”

“…Additionally, the combination of decreased muscle contractile efficiency ( Tajali et al, 2022 ), and decreased capacity of the nervous system including insufficient integration of sensory information, and impaired neuromuscular functions under fatigue can alter feedforward and feedback control of postural sway ( Akulwar and Mulgaonkar, 2017 ; Zemková et al, 2021a ). For example, fatigued healthy subjects exposed to external perturbations have shown longer activation latencies, an increase in electromyographic amplitude, reduced muscle activity, and increased co-contraction ( Zemková et al, 2021a ; Zemková et al, 2021b ).…”

Prolonged periods of sitting at work can increase trunk muscle fatigue from the continuous contraction of deep trunk muscles. Insufficient activity of these muscles can decrease muscular support to the spine and increases stress on its passive structures. This can lead to reduced spinal mobility and impaired postural stability. It may also stimulate nociceptor activity leading to pain. However, frequently used recovery modalities such as muscle strengthening and stretching exercises, can be time-consuming, impractical, and difficult to implement in the workplace. Diaphragmatic breathing exercises, which increase the activity of the deep trunk muscles by raising intra-abdominal pressure, seem to be a suitable alternative. However, little is known as to what extent diaphragmatic breathing exercises contribute to the reduction of fatigue induced by prolonged sitting. This paper presents a study protocol that aims to investigate the acute effect of diaphragmatic breathing exercises on recovery of fatigue-induced changes in spinal mobility and postural stability in sedentary middle-aged adults at risk of developing non-specific low back pain. Twenty sedentary adults aged between 25 and 44 years will perform Abt’s fatigue protocol, followed by 1) active recovery using diaphragmatic breathing exercises and 2) passive recovery in the form of lying on the bed, respectively. There will be 1 week of rest in-between. Pre-fatigue, post-fatigue, and after the active and passive recovery, spinal mobility and postural stability will be evaluated using the spinal mouse device and a posturography system, respectively. The electromyography will be used to determine the muscle-fatigue conditions. We hypothesize that active recovery in a form of diaphragmatic breathing exercises would be more effective in restoring spinal mobility and postural stability followed by the fatigue of back and hamstring muscles compared to passive recovery in sedentary adults. Increasing core and respiratory muscle strength via these exercises could be beneficial for overall mobility and stability of the spine. Reducing compressive stress on the passive structures of the spine may be also beneficial for lowering low back pain. Therefore, we believe that diaphragmatic breathing exercises have the possibility to be incorporated into the workplace and contribute to better back health in sedentary middle-aged adults.Clinical Trial Registration: [https://www.irct.ir/trial/67015], identifier [IRCT20221126056606N1].

“…Control of posture is a function which undertakes the summation of auditory, visual, and somatosensory signals information to survey the position and movement of body in space and capacity to create force to control body position. 1 To maintain the body in stable position the important postural control strategies mainly focus around two major joints that is hip and ankle. 2 People with no disease condition can reposition their trunk with more clarity in an un-fatigued state.…”

Control of posture is a task that requires the summation of auditory, visual and somatosensory signals. Trunk plays a vital role in the loading of energy and connecting the lower and upper extremities. Nurses spent a lot of time on activities involving frequent bending and turning movements. These postures and movements when used for prolonged duration place static and dynamic stability demands and may increase the demands on the trunk muscle groups resulting in high risk for developing low back pain. The aim of this study was to find a relation between trunk extensor muscle endurance and dynamic postural stability among Nurses. 103 female and male nurses were recruited for the study based on the selection criteria. The nurses were evaluated for the trunk endurance using Bearing-Sorenson’s test. The Y-balance test and berg balance scale was used to know the dynamic postural stability. The mean trunk extensor muscle endurance was found to be 83.26 ± 17.72 seconds. The ‘Y’ balance was 88.24 ± 11.73 on the right side and 89.16 ± 12.09 on the left side. The mean Berg balance score was 30.13 ± 3.59. There was no significant relationship was noted between trunk muscle endurance and Y balance (p=.57). No significant association was observed for trunk muscle endurance with a Berg balance score (p= 0.727). We found no significant relationship existing between trunk extensor muscle endurance on dynamic postural stability among nurses. Trunk extensor muscle endurance may not be the major factor in maintaining dynamic postural stability. Keywords Posture, Muscles, Low Back Pain, Balance
