Methods and Measures: sEMG was examined by cervical-brachial eight muscles (erector spinae neck, trapezius, supraspinatus, infraspinatus, pectoralis, anterior deltoid, middle deltoid and latissimus dorsi) of the right shoulder of 16 subjects (8 men and 8 women).
When we faced the same muscle in front of the tube placement or not crawling, we see that the infraspinatus muscle and the erector spinae of the neck are the only ones that have statistically significant changes in muscle activation due to the suppression of head movement (erector spinae) and resistance underwater recovery phase (infraspinatus) As the underwater recovery by the application of the tube causes the neck muscles are less active.
A change in lumbar curvature can alter fascicle obliquity, lever arm distance, and the length-tension relationships of the erector spinae (McGill et al 2000, Raschke and Chaffin 1996, Singh et al 2011, Tveit et al 1994).
Hence, the aim of this clinical commentary is to discuss some of the biomechanical principles associated with lumbar posture, spinal loading, and erector spinae muscle activity and highlight the implications for the education and the rehabilitation of those involved in manual handling activities.
Studies that have simulated repeated loading at end range of lumbar flexion have found an attenuation of the erector spinae reflex response to aid spinal stabilisation and an increase in spinal ligament and intervertebral disc creep (Adams and Dolan 1996, Solomonow 2012, Solomonow et al 1999).
The influence of lumbar posture on erector spinae geometry
The major trunk muscles responsible for resisting and controlling the bending moment and anterior shear forces acting on the lumbar spine when lifting and lowering are the erector spinae (Macintosh and Bogduk 1986, McGill et al 1988).
The upper erector spinae consist of the thoracic fibres of iliocostalis lumborum and longissimus thoracis.
The local subgroup of the erector spinae are those muscles whose fascicles originate and insert on the vertebrae of the lumbar spine and pelvis (Bergmark 1989).
Another key muscle of the local erector spinae is multifidus.
