Types of Walkers and Features
Glides
Glides are small, plastic attachments placed on the posterior
legs of walkers typically in combination with wheels on the
front legs (Fig. 11A.17A). They promote a smooth forward
progression without having to lift and place the walker with
each step. They are typically made of high-density plastic
in an inverted-mushroom shape. Other common glide
designs include a 1-in (2.54 cm) diameter “disk” with a central
stem that slides into the tubular leg and is tightened
into place with a screwdriver, and a fitted cap that is placed
directly onto the walker leg (in the same manner the rubber
tip is attached). Another style of glide incorporates a tennis
ball within a fixed housing.
