Physiotherapists in Congleton treat many different conditions including the issues profiled below.

Forward Bending Actions Which Can Injure The Spine

In normal circumstances people bend their lumbar spines by 80-100% of the available movement when they bend over to the floor to pick things up. Adding an awkward movement such as to one side increases the stretch on the facet joint of the other side. This indicates that it is easy to get to the maximum bend limit of the lower spine by doing something easy like reaching down to the feet to put on shoes. Long periods of remaining flexed, such as sitting for a long car journey, forces the ligaments to relax, decreasing the protective muscular mechanisms and increasing the chances of suffering a disc prolapse.

If the muscles get tired by repetitive actions of lifting or bending over then their protective care of the spine is also diminished. In the anatomical examination of spines after death there has been shown to be a 20% incidence of rupture of the ligaments which connect the spines of the individual vertebrae at the back. As these ligaments are fully stretched when the spine is fully bent it is likely that bending injuries due to too much flexion of the spine are very common as people are suddenly forced into bend by an accidental movement.

Disc Nutrition and Posture

The supply of nutritional substances to the inner parts of the discs is in general poor and a lack of this supply is connected with degenerative disc changes. Large differences in the compression forces inside an intervertebral disc can be generated by relatively small changes in posture. These changes have correspondingly large effects on fluid flow out of and into discs and on diffusion of metabolic agents into the disc. The effectiveness of the transport of these materials depends on how far they have to travel from the nearest blood vessel which is usually in the vertebral endplate (top or bottom of the disc).

When bending, the back of the disc walls is stretched and the fronts are compressed, with stretching making the wall thinner and therefore more easily crossed by nutrients. This brings more food supply into the central area of the rear of the disc, the area which receives least nutrition. Compression from movement also squeezes water from the disc and as it returns when the pressure is relieved the incoming water brings nutrients along with it. Changes from a lordosis to a flexed position regularly increase the fluid flow in and out of the disc, encouraging the transport of nutrients.
