Background: The purpose is to examine the myoelectrical activity of erector spinae muscle in patients with acute and sub-acute mechanical low back pain (MLBP) and normal subjects.Methods: A total of 30 patients 15 with MLBP and 15 normal subjects of both genders participated in the study with convenient sampling; all were aged between 20-50 years. The participants were asked to perform movement which was paced by computer running a program and the myoelectrical activity of erector spinae muscle in patients with acute and sub-acute mechanical low back pain and normal subjects were examined.Results: This study stated that patients with MLBP has increased or over activity of erector spinae muscle during complete lumbar flexion when the muscle should be electrically silent. This was observed with help of EMG graph where increase in activity was observed with increase in amplitude, duration and time in graph.Conclusions: There is increase in the amplitude, duration and time in flexion relaxation phenomenon (FRP) in mechanical low back pain patients when compared to normal subjects.

Experimental observation of human bone marrow mesenchymal stem cell transplantation into rabbit intervertebral discs

Abstract. Allogeneic bone marrow mesenchymal stem cell (BMSC) transplantation has been investigated worldwide. However, few reports have addressed the survival status of human BMSCs in the intervertebral discs (IVDs) in vivo following transplantation. The current study aimed to observe the survival status of human BMSCs in rabbit IVDs. The IVDs of 15 New Zealand white rabbits were divided into three groups: Punctured blank control group (L1-2); punctured physiological saline control group (L2-3); and punctured human BMSCs transfected with green fluorescent protein (GFP) group (L3-4, L4-5 and L5-6). One, 2, 4, 6 and 8 weeks after transplantation the IVDs were removed and a fluorescence microscope was used to observe the density of GFP-positive human BMSCs. The results indicated that in the sections of specimens removed at 1, 2, 4, 6 and 8 weeks post-transplantation, no GFP-positive cells were observed in the control groups, whereas GFP-positive cells were apparent in the nucleus pulposus at all periods in the GFP-labeled human BMSCs group, and the cell density at 6 and 8 weeks was significantly less than that at 1, 2 and 4 weeks post-transplantation (P<0.001). Thus, it was identified that human BMSCs were able to survive in the rabbit IVDs for 8 weeks.

“…The mechanical loads applied to the spine during classical ballet are high (Alderson et al Although young dancers (aged 12-27) had a lower incidence of back pain per activity hour compared with age matched controls; when their activity exceeded above a threshold of 30 hours/week the incidence of back pain increased (McMeeken et al 2001). Dance training over 8.5…”

“…The compressive loads on male dancers during lifting their partners have been shown to exceed the National Institute of Occupational Safety and Health, Back Compression design Limit (3400N) ).

“…Factors which have been cited as contributing to dancers' low back injury and pain include; excessive compressive load ) and volume of activity (Kadel et al 1992, McMeeken et al 2001, Purnell et al 2003; excessive range of movement or hypermobility (Klemp et al 1984); presence of scoliosis (Hakim and Grahame 2003, Hamilton et al 1992; posture (Solomon et al 2000); low (Benson et al 1989) and relatively high Body Mass Index (McMeeken et al 2002); limited range of lower limb external rotation compared to other dancers (Bachrach 1986, Kelly 1987, Solomon et al 2000; and inadequate muscle strength, control (Gelabert 1986, Kelly 1987, Solomon et al 2000 and endurance (Swain and Redding 2014). The relative contribution of each of these factors to LBP in dancers is yet to be identified.…”

Physiology and pathophysiology of low back pain in ballet dancers

Classical ballet dancers combine artistry and physical skills to perform graceful and exciting movements. Lengthy, exacting dance training potentially promotes unique adaptation of motor control to; execute these movements; maintain optimal physiological function, and provide stability to avoid injury and pain. Yet low back pain (LBP) is common in dancers. Differences in motor control are frequently observed between non-dancers with and without LBP. This often involves reduced and delayed activity of deep trunk muscles and augmented activity of superficial muscles. These changes are proposed to affect the control of movement and stiffness of the trunk. LBP is also associated with deficits in postural control, an aspect of motor control, which depends on control of the trunk. Some features of adaptation in motor control are relatively common; but there are some features that are specific to individuals or different populations. It is essential to understand how motor control is adapted in elite classical ballet dancers with LBP as less optimal motor control has potential to impair performance and limit the capacity to dance. The overall objective of this thesis was to investigate aspects of motor control in dancers with and without LBP, with specific attention to trunk muscle morphology and to postural stability.Studies I and II investigated trunk muscle size, symmetry and function, in dancers with and without LBP, at rest and during simple manoeuvres, with magnetic resonance imaging (MRI). Reduced size of the multifidus muscle was observed in dancers with LBP and dancers with both back and hip/pelvic region pain. This finding is similar to that for nondancers. Study II provided preliminary evidence of a behavioural change in transversus abdominis (the deepest abdominal muscle); expressed as reduced length change of this muscle measured with MRI, in dancers with LBP. Thickness of transversus abdominis, obliquus internus abdominis and multifidus muscles were asymmetrical in dancers but this was not related to LBP. This may be related to repetitive performance of asymmetrical movements. Studies III and IV investigated postural control. In Study III, the trunk was perturbed in order to measure the dynamic properties of stiffness, damping and mass as an indication of control of the trunk. Dancers with LBP had less damping (control of velocity) than dancers without LBP, but this could be changed with motor imagery in the dancers with LBP. Study IV used linear and non-linear measures of centre of pressure trajectories to investigate standing balance in dancers with and without LBP and nondancers. Balance was measured with the feet in parallel and the dance-specific turned out 'first' position; which increases the dependence on trunk motion for balance in the anteroposterior direction. Dancers without LBP used more movement to control balance iii than non-dancers. These findings suggest that "less" movement does not define optimal balance in dancers. Dancers with a history of LBP used strategies that were more s...
