Following publication of the original article [1], the authors reported the following errors:

  • Figure 1. Information regarding the population inclusion/exclusion criteria was previously missing and has been added as a footnote.

  • Part 2 quantitative online survey results: The text describing the activity domains (ADLs) most frequently raised for each item in the online survey has been corrected to nine items being more frequently associated with a different ADL domain in the quantitative online survey when compared to the interviews. The overall skip rate (12%) and country response percentage rates for the following countries US (94%), Canada (92%), France (83%), UK (87%), Poland (86%), and Spain (80%) have been corrected.

  • Table 3. The footnote letters for items 4, 8, 12, 15, 24, 25, 30, and 31 have been corrected.

    Table 3 Most frequently reported ADLs in relation to MFM32 item
  • Figure 4. The number of participants selecting voice, difficulty sleeping, and other as important to maintain/improve has been corrected.

    Additional symptoms and impacts that are important to maintain/improve not captured on motor function assessments. *Breathing/respiratory function (n = 12), muscle strength (n = 7), chewing/coughing/swallowing (n = 4), mental/psychological problems (n = 4), elimination of contractures/scoliosis (n = 3), general physical safety (n = 2), ability to feed oneself/brush teeth/sign name (n = 1), comfort (n = 1), exercise assessment (n = 1), losing weight (n = 1), moving position (n = 1), poor blood circulation/cold feet (n = 1), sexual life (n = 1), social interactions (n = 1), reason unclear (n = 1)

Additional information has been added in the Acknowledgements and Declarations sections:

  • Carl Cooper (Adelphi Values) wrote the first draft of the manuscript.

  • The online survey was conducted following market research principles.

  • AB, TD and CV received consultancy fees from Roche for this project.

  • LY, SR and ADM are employees of Charles River Associates commissioned by Roche to conduct the online survey.
