Spasticity is thought to be caused by an excessive increase of excitatory signals from sensory nerves without proper inhibition by GABA.
An incision is made in the lower back just above the buttocks and the nerves accessed and dealt with are in that area of the spinal column. SDR’s result is fundamentally unlike orthopaedic surgical procedures, where any release in spasticity is essentially temporary. Because the muscles may have been depending on the spasticity to function, there is almost always extreme weakness after a rhizotomy, and the patient will have to work very hard to strengthen the weak muscles with intensive physical therapy, and to learn habits of movement and daily tasks in a body without the spasticity. 2 and 6, since this is the age range where orthopedic deformities from spasticity have not yet occurred, or are minimal.
It is also variously claimed by clinicians that another advantage to doing the surgery so young is that it is inherently easier for these extremely young children to restrengthen their muscles and to re-learn how to walk, often having the effect that later in life, they do not even remember the period of time when they lived with the spasticity at all. A counter-argument against the prevailing view concerning the younger years is that it may actually be quicker and easier to restrengthen an older patient’s musculature and regaining of walking may happen faster with an older patient due to the fact that the patient is fully matured and very aware of what is going on, and so may work harder and with more focus than might a young child. These two schools of thought have equally objectively valid bases for their formation and thus are each defended quite intensely by their respective proponents. New York as well as W.
3 dorsal rhizotomies to improve his patients’ quality of life. Sherrington’s studies were used as a basis for performing posterior root rhizotomy for the relief of spasticity in the lower limb muscles. Rhizotomy for spasticity purposes did indeed then proceed to take about a 50-year hiatus for reasons as yet not thoroughly distilled from the clinical records and reports on the phenomenon. Foerster technique, postoperative sensory loss was too frequent, or by the fact that with their technique, spasticity often returned.
