It is crucial to keep the following points in mind before selecting a 4 wheeled walker. The height should not be too high as the user may find it difficult to bear weight through their arms as their elbows may not straighten. The height should not be too low the user will lean forwards creating a poor posture and back problems. However, for people with backward leaning tendency a walker with a slightly shortened height must be selected to encourage the forward leaning posture. Do remember to wear supportive footwear while being measured for height.
