Electromyography (EMG)  is a test done with electrodes and/or needles inserted into or onto specific muscles to assess muscle activation at rest and during contraction. For Michael, my patient who has spinal muscular atrophy (SMA), we performed an EMG on different muscle groups to assess resting and activation…

Boosting the production of the growth factor protein NRG1-III improved motor nerve fiber development in the early stages in a mouse model of spinal muscular atrophy (SMA), a study showed. NRG1-III was unable to prevent nerve fibers from degenerating or improve motor function or survival in older mice,…

In adults with spinal muscular atrophy (SMA), treatment with Spinraza (nusinersen) in a clinical trial was tolerated well and led to improvements in arm function and self-rated health. These findings add to data from several studies that have examined the safety and efficacy of Spinraza in older…

Michael, a patient who has spinal muscular atrophy (SMA), has experienced reductions and increases in his lung capacity throughout his life due to his genetic disorder. This is a common occurrence in this population due to the disease’s progression on the muscles responsible for respiration. Just recently, this…

One of the first objectives we wanted to address when Michael, who has spinal muscular atrophy (SMA), began physical therapy in 2017, was swelling in his feet and ankles. There are many ways we have addressed the swelling and edema in his legs, including reducing his salt intake.

The one-time gene therapy Zolgensma (onasemnogene abeparvovec) will now be routinely accessible at low or no cost to presymptomatic infants in England who are genetically predisposed to spinal muscular atrophy (SMA). Per updated recommendations from the country’s National Institute for Health and Care Excellence (NICE), this…

High doses of Evrysdi (risdiplam), an approved daily therapy for spinal muscular atrophy (SMA), affected the development of sperm in rats and monkeys, a review of 14 preclinical safety studies reported. No damage was evident in immature sperm derived from stem cells, and changes affecting sperm ended…

Evaluating the strength of nerve cell impulses to muscles may be a good way of predicting motor skill recovery after Zolgensma (onasemnogene abeparvovec) treatment in infants with spinal muscular atrophy (SMA), a recent study suggests. The research showed that compound muscle action potential (CMAP) amplitudes in the…
