Physiotherapists in South Yorkshire treat many different conditions including the condition profiled below.
Repeated Loading of Lumbar Discs
Lower loads than the sudden compression loading which occurs seldom can cause a disc prolapse if the loading in a bent position is repeated in a cyclical manner. This can be caused in discs which are reasonably young and causes a large split in the rear of the disc wall to one side or another, allowing the central nuclear material to ooze out. In several examples the layers of the disc wall which were the most outer ones did not split and form a fissure and the nuclear material protruding through the fissure inside built up behind the remaining layers in a bulge. As the ligament overlying this has many nerve endings, such a bulge could cause pain.
Older discs were shown in some cases to have fissures which are already present before any experimental loading and these discs did not prolapse during the loading tests, perhaps because the fissures had healed or because discs in poorer condition are too stiff and fibrosed to prolapse. If twisting, side bending or compression is added to bending then prolapse can occur more easily with less bend of the back. In some cases the nucleus may protrude out but in others the outer disc walls can protrude themselves.
Damage To The Spine By Bending Forward
Injuries sustained in bending occur when the forces involved exceed the coping capacity of the tissues of the spinal structures. The movements of the lumbar spinal bones in a living person undergoing a rapid forward bend are controlled mostly by the strength and length of the disc and ligamentous tissues. Initial damage occurs to the more superficial ligaments which connect the spines of the individual vertebrae posteriorly and if some side bending or twisting motion is added then the capsules of the facet joints can be stretched to their limits. The rear part of the disc wall may act like a ligament in extreme bend, restricting further bending.
In slower bending where a position is held for a time the resistance of the spinal tissues to bending decreases, allowing greater movements between the vertebrae and a slow change in the internal disc alignment. Due to the mechanical properties of the tissues quick movements have an increased likelihood of damaging the ligaments and discs, while holding the spine in flexion for some time may both reduce the protection activity of the back muscles and the ability of the ligaments to protect the lumbar segments as they move.
Physiotherapists in South Yorkshire have contributed some of the many articles on this site such as the one extracted below.
In the back of the upper leg (the posterior thigh) lie the hamstrings, a group of muscles which are particularly vulnerable to injuries and ongoing pain problems in athletic individuals. The upper part of the muscles in the upper thigh and lower buttock are injured much more often than other parts, with the outer side of the leg also more affected. There are no normal names for the three muscles involved which are called the semitendinosus, biceps femoris and semimembranosus, with the biceps femoris being most often involved.Hamstring injuries are classified for ease of diagnosis and treatment into various grades of severity. The least serious injury with a number of damaged muscle fibres is a grade 1 injury, rated as a mild muscle strain. More serious involves a larger number of muscle fibres being damaged and a reduction of muscle strength which is obvious on testing and this is a grade 2 injury. In the most serious or grade 3 injury there is a rupture right through the substance of ...
