Active-NBS is a study to evaluate the muscle development of patients with spinal muscular atrophy (SMA) who are diagnosed at birth.
Medicines have become available in the last decade, and many patients are treated very early. Treatments are most effective if used before the patient develops symptoms. However, some patients may show symptoms by the time they receive treatment. This means that even with early diagnosis, they might still develop muscle weakness despite treatment. The investigators want to see when the movements of patients diagnosed at birth differ from normal development. This information will help identify the best time to give additional medicines currently being developed to support the muscle.
The investigators will track the progress of up to 60 patients over a maximum of 30 months using wearable technologies which are worn at home. The investigators aim to validate their outcomes for use in this age group. The wearable devices are called Syde and Motor Assessment of an Infant in a Jumpsuit (MAIJU).
They will be worn at regular intervals during the study and will not involve extra hospital visits for patients. The study will also recruit up to 30 healthy control participants and follow them for up to 30 months. This will help define normal development with use of the Syde device.
Active-NBS will be conducted in the UK and internationally using a federated data model. Collaborative sites will collect harmonised data in accordance with the Active-NBS protocol, with data integration and oversight managed by the University of Oxford. International sites may contact the Oxford study team to establish collaboration.

| To identify the earliest time-point of future motor impairment (Test cohort). | Assessment of BIMS from MAIJU until the acquisition of ambulation, then SV95C from Syde. | BIMS are collected at baseline (month 0) and monthly thereafter at months 1, 2, 3, 4, 5, 6, 9, 12, 18, 24, and 30. SV95C measured at baseline (month 0) and every 3 months at months 3, 6, 9, 12, 18, 24 and 30. Maximum of 30 months. |
