AAOS describes a cane for minor balance or stability problems, weakness, injury, or pain. Fit and technique matter; the top should meet the wrist crease with a slight elbow bend, and it is generally held opposite the side needing support.

Three aids. Three different questions.
AAOS states that a walker provides more balance and walking support than a cane. Mayo Clinic notes that walker types differ in stability and mobility; selection and fitting belong with a clinician.
Mayo Clinic guideMayo Clinic notes that a four-wheel walker may include a seat when endurance is a concern. For any cane-seat or rollator seat, verify the exact manual, labeled capacity, contacts, locks or brakes, and permitted surface. This lab never supplies a generic rating.
NHS category guideThe rule beneath the aid
Gravity does not care what the product is called.
Weight can leave the feet only through a real second load path. Static rest remains stable only while gravity's projected line stays inside the ground-contact polygon. Slope moves that projection. The closest edge is the honest limit.
A cane can help with minor balance or stability problems; a walker provides more support.
American Academy of Orthopaedic SurgeonsPain changes the safety boundary.
Seek urgent local medical help for severe foot pain, inability to walk, shape change, or a snap/grinding injury. Get professional advice for worsening or recurring pain, tingling or loss of sensation, weakness, or foot pain with diabetes.
These examples follow current NHS guidance; local services differ. Do not use a mobility-aid simulator to delay assessment.
