Advances in mobility aid use reporting: situational context and objective measurement improve understanding of daily aid use in older adults.

Background: Understanding mobility aid use has implications for falls risk reduction and aid prescription. However, aid use in daily life is understudied and more complex than revealed by commonly used yes/no self-reporting.

Aims: To advance approaches for evaluating mobility aid use among older adults using a situational (context-driven) questionnaire and wearable sensors.
