Spinal Muscular Atrophy (SMA)

Spinal Muscular Atrophy (SMA)

What is spinal muscular atrophy?

SMA is a genetic disease that effects the central nervous system. The spinal cord contains an amazing collection of nerve cells that work to control our muscles. SMA is known as a muscular disease as it primarily effects the muscles. Atrophy is a term used to describe the loss of muscle bulk due to the muscle reducing in size.

What causes SMA?

Chromosome 5 SMA (which is the most common form of SMA) is caused by a deficiency of SMN. SMN ‘survival of motor neuron’ is a motor neuron protein – it plays a big role in gene expression in motor neurons.

Medical treatment for SMA

Spinraza has been approved for the treatment of SMA. It is a drug that has been designed to treat the underlying defect in SMA, therefore it may be useful in slowing, stopping or reversing the symptoms ofSMA.

Zolgensma is a gene-replacement therapy. It is a one-time IV infusion usually administered to children younger than 2 years old.

Rizdiplam has been approved for children and adults with SMA over the age of 2 years old. It is a medication that has been designed to enhance the production of a ‘backup’ gene known as SMN2.

How can we help at Complete Neuro Rehab in the treatment of SMA?

We assess the condition on the first consultation and once our therapist has a thorough idea of the symptoms, they will work with you to devise a therapy plan.

Treatment plans may include:

·     Stretches and positioning

·     Postural re-education

·     Movement activation on muscles that require strengthening

·     Functional movement work such as rolling training

·     Pilates based strengthening

·     Transfer advice

·     OMEGO therapy – a device we can use to move the limbs through passive and active range of movement without the need for full weight bearing. This is a fun and engaging therapy option with the opportunity for leg press style strengthening.

·     Lite-Gait – body weight support

·     Exercise therapy and support to complete home exercises.

FAQs

What is the role of physical therapy in managing SMA?

Physical therapy plays a vital role in managing Spinal Muscular Atrophy (SMA) by helping individuals maintain mobility, strength, and overall function. While physical therapy cannot cure SMA, it helps to alleviate symptoms and improve quality of life. At Complete Neuro Rehab, our therapists use a combination of movement activation, postural re-education, and functional training to strengthen muscles and enhance joint flexibility. Additionally, devices like Lite-Gait and OMEGO therapy provide targeted support for safe and effective rehabilitation. Therapy programs are tailored to each individual’s needs, focusing on improving mobility and delaying the progression of muscle weakness.

What are the early signs of Spinal Muscular Atrophy (SMA)?

The early signs of Spinal Muscular Atrophy (SMA) can vary depending on the type of SMA, but common symptoms often include muscle weakness, particularly in the limbs and trunk. In infants with Type 1 SMA, signs may include delayed milestones such as difficulty holding up the head, sitting, or rolling over. As the condition progresses, affected individuals may experience trouble with swallowing, breathing, and other vital functions. Early detection is crucial, as prompt treatment can significantly improve the chances of slowing down disease progression.
