Functions and Sensors of Smart Walkers From 2015 to 2024: Scoping Review.
Nicole Strutz, Hanna Brodowski, Stephan Schulze
PMID 42189759WHAT IT FOUND
Smart walkers use many sensors, but most were tested in labs with younger adults without symptoms.
Gait and balance measurements were often not checked against reference systems, so they cannot yet guide clinical decisions.
Key findings
01Most included studies were laboratory-based, and younger adults without symptoms were the most frequently studied group.
02Camera and LiDAR sensors were the most prevalent sensor modalities.
03Only 8 of 35 studies measuring gait-relevant data used reference systems for validation.

What it does not show
No quality appraisal was done, so the review maps what was studied but does not judge whether the included studies were reliable. Most studies were laboratory-based and used asymptomatic or younger adults, so findings may not apply to older adults who need walkers in clinical or home settings. Many included studies had small samples, ranging from 1 to 43 participants, and 5 did not report participant numbers. Validation against reference systems was uncommon for gait-related sensors; many studies did not report how accurate the measurements were. The review excluded two-wheeled walkers, so it does not cover all walking aids clinicians may consider.
Declared interests
Funding came from the Federal Ministry of Education and Research in Germany (grant 16SV9335). The authors declared no conflicts of interest.
The easy way to misread this
Do not read this review as evidence that smart walkers reduce falls or improve mobility. It maps functions and sensors; most studies were laboratory-based, involved younger adults without symptoms, and gait measurements often lacked validation against reference systems.
