New Developments in the "ICF World"

Since the last Branch Newsletter there have been new developments in the "ICF world"... More than 30 updates (or changes) to the ICF have been approved by WHO. The majority of these updates stem from proposals that tried to integrate elements from the children and youth version of the ICF (ICF-CY) into the reference version of the ICF. These updates include minor text changes, addition or modification of inclusion and exclusion criteria, as well as additions of new categories. For example, to d4700 Using human-powered vehicles additional text was included to reflect specific characteristics of children and youth and wheelchair users; the description now reads "Being transported as a passenger by a mode of transportation powered by one or more people, such as riding in a pram or stroller, wheelchair propelled by another, rickshaw or rowboat. An example of a new category is d451 Going up and down stairs Moving upwards and downwards so that at least one foot is always on the ground such as ascending and descending stairs or curbs. Exclusions: walking (d450); climbing (d4551). This new category is intended to differentiate from d4551 Climbing. Previously d4551 Climbing was the only category available to describe both the action of walking up and down stairs and, for example, rock-climbing. However, rock-climbing and walking up and down stairs are quite different activities of mobility. Now it is possible to differentiate these actions with different codes.

To see all the ICF updates approved by WHO since 2011, go to the WHO website here: WHO plans to make a PDF of the updated ICF available on the WHO website. In the meantime, the majority of these ICF updates can be seen on the online ICF Browser (; WHO is in the process of ensuring that all of the ICF updates are displayed. Note that the ICF Browser no longer contains the ICF-CY. The ICF-CY in PDF form is available on the IRIS page on the WHO website here:
