Once we get past the destructive effects of sagittal curve loss on the column itself, there are other problems to be reckoned with. Famed neurosurgeon, Alf Brieg’s studies clearly show modest decreases in the cervical lordosis will generate tensile mechanical forces to the spinal cord, meninges and nerve roots as well. Tensile stretching of nerve roots tends to result in hyperexcitability (facilitation). In the CNS, tensile stretching has been shown to be a causative factor in producing pathological changes in the spinal cord itself. Long term results are scar tissue formation (sclerosis) within the cord and meninges and mechanical irritation and scarring of the nerve root and sleeve (root sleeve fibrosis).
Good Posture: Good posture helps the body stand, walk, sit, and lie in positions that place the least strain on supporting muscles and ligaments. Maintaining proper posture requires adequate muscle flexibility and strength, normal joint motion in the spine and other body regions, as well as efficient postural muscles that are balanced on both sides of the spine.
