Communication skills among children with spinal muscular atrophy type 1: A parent survey

Area of Science:

• Neurology
• Genetics
• Speech-Language Pathology

Background:

• Spinal muscular atrophy (SMA) is a common fatal autosomal recessive disorder.
• SMA Type 1 (SMAT1) presents with severe oral motor weakness and dysarthria, often leading to anarthria.
• Limited research exists on augmentative and alternative communication (AAC) for SMAT1, despite its impact on quality of life.

Purpose of the Study:

• To investigate communication skills and opportunities in children with SMA Type 1.
• To evaluate the perceived benefits and barriers of AAC, specifically speech-generating devices (SGD), for this population.
• To understand the impact of SGD on quality of life and functional communication.

Main Methods:

• A parent survey was developed and administered by investigators.
• The survey collected data on communication abilities and AAC use in children with SMA Type 1.
• Data analysis focused on parent perceptions of receptive vs. expressive language and SGD benefits/barriers.

Main Results:

• Parents perceived greater receptive than expressive language abilities in children with SMA Type 1.
• Speech-generating devices (SGD) were highlighted as beneficial for improving functional communication.
• Barriers to SGD acquisition and implementation, including access and funding, were identified.

Conclusions:

• SGD implementation can significantly enhance quality of life for children with SMA Type 1.
• Expanded functional communication through SGD leads to valued improvements for families.
• Addressing access and funding barriers is crucial for wider SGD adoption in SMAT1.
