A subject performs a mobility assessment while using a cane. The cane use is collected because it affects interpretation of the performance result. Where should the assistance or device context go if it is collected as part of the assessment?

In AE because a cane implies an adverse event.

In FT or SUPPFT qualifiers such as assistive-device details, depending on the available variable.

Only in DM.

It should be dropped because it is not the score.
