(Stretching the upper back forward and backward is thereâ€" fore a good exercise to help limber the spine.) b Between the vertebrae lie the discs, which are circular structures acting as shock absorbers. The discs have a semiâ€"fluid centre and an outer ring of resistant tissue. An injury to the disc begins as a small tear in the outer ring causing the inner area to be partially exposed. The disc most easily injured lies near the base of the spine. There are two common reasons for this. Because the disc sits at an angle between the vertebrae and the triangularâ€"shaped bone which sits at the base of the spine, it encourages a rubbing action which can be irritating. Secondly, the ligaâ€" ment which supports the lower back is thin and narrow, almost encouraging injuries. (Ligaments hold the vertebrae together.) Qeru)ice . . . worthy of your confidence.

If these muscles are weak, strain is increased upon the ligaments supporting the spine. The result is termed lowâ€"back strain. Strain occurs when muscles, ligaments, or joint structures (usually all three) undergo sudden or prolonged stress or tension. Such strains often leave no permanent damage to the joints, ligaments or muscles. Sprains occur from a severe wrenching action, causing some tearing of the tissues. Sprains heal by formation of scar tissue, but the tissues do not return to their original state. First, bend your arm at the elbow and hold it above your head for three minutes. The arm will soon begin to ache. During this time the arm muscles contract. Energy for the conâ€" traction comes from sugar and oxygen, and as the sugar metabolizes, acid forms. The acid stimulates sensitive nerve endings, initiating messages along the nerves to the brain. The brain then tells you that you are experiencing pain. At this point you should do something to alleviate the pain. (You can put your arm down now.) Next, press back the long finger on your left hand with the fingers of your right hand. Keep up the pressure until the finger starts to hurt, then release it suddenly. The pain vanishes. In this experiment, the abnormal stretching of the joint has caused pain. When pressure is withdrawn, the messages stop and the pain ceases. Two experiments may help you understand how pain develops. 3 Charles S1.
