Each vertebra is made up of a large bone called the body.The 17 participants began Spinraza therapy from about 3 to 32 years old and received nine to 12 doses by SIC. They act as shock absorbers when you walk or run.The vertebrae protect and support the spinal cord, and bear most of the weightput on you spine. Between your vertebrae are flexible intervertebral disks.
It begins at the base of your skull and ends at your pelvis. The SIC device (not Spinraza) caused all 14 AEs that were related to treatment.Your spine (or backbone) is a stack or column of 24 bones (vertebrae) plus the fused bones of the sacrum and coccyx. The spinal cord itself has neurological segmental levels which are defined by the spinal roots that enter and exist the spinal column between each of the vertebral segments.The team recorded 26 adverse events (AEs) among 12 participants who received a total of 203 doses of Spinraza. The spine consists of a series of vertebral segments. The spinal cord is situated within the spine.
Spine Vertebrae Manual Dexterity Increased
However, these parameters did not change with Spinraza treatment.The levels of pNF-H in blood samples of SMA patients were similar to values collected from a control group of 55 healthy family members. Sum Total Force also moderately correlated with phosphorylated neurofilament heavy chain (pNF-H) in the CSF, a marker for motor neuron degeneration. There was no change in RHS or lung function.All of these patients reported one or more subjective improvements in speech (25%), head and neck control (42%), arm strength (42%), physical endurance (58%), and the use of hands for handwriting, typing, or maneuvering a power wheelchair (75%).Pediatric quality of life (PedsQLTM) scores comparing physical to emotional disability did not change in response to therapy, except for the National Institute of Health (NIH) Toolbox Emotion Domain, with a small but significant increase of 8%.Before treatment, the Sum Total Force, a combined measure of muscle strength by dynamometry in various body parts, showed a strong correlation with the compound muscle action potential (CMAP), which assesses electrical impulses in muscle function. The mean grip strength improved by 44.9%, but strength in other muscle groups was unaffected. The maximum RHS score is 69, with higher scores reflecting better motor function.Of these 11 patients, nine had spinal fusion, and two had scoliosis.The mean performance of the Nine Hole Peg Test to measure manual dexterity increased in the dominant hand by 15.9% and in the non-dominant hand by 19%. One patient experienced a headache and low-grade fever after 12 doses, and the CSF reservoir became infected with Staphylococcus epidermidis resulting in its permanent removal.From an analysis of 138 CSF samples withdrawn for testing (average eight per patient), half had elevated red blood cells, but patients did not experience symptoms.A subset of 11 patients was included in the efficacy analysis, in which Spinraza began at a mean age of 18 and who received a mean of 11 doses over about two to three years.The mean pre-treatment Revised Hammersmith Scale (RHS) score for motor function was 7.6.
