Types of walkers beyond the basic model include:

• Rollators. This common style of walker consists of a frame with four wheels, handlebars, and seat so the user can rest as needed. Rollators also include hand breaks as a safety feature.
• Knee walkers. Similar to a rollator, this device allows the user to rest their knee on a padded cushion while propelling them- selves forward with their stronger leg.
• Walker-cane hybrids. A cross between a cane and a walker, this mobility aid has two legs rather than a full frame. It can be used with one or both hands and provides greater support than a standard cane.
