Chapter 3. Safer Patient Handling, Positioning, Transfers and Ambulation
3.5 Assistive Devices
An assistive device is an object or piece of equipment designed to help a patient with activities of daily living, such as a walker, cane, gait belt, or mechanical lift (WHO, 2018). Assistive devices also allow the the healthcare worker to transfer and move patients in a way that reduces risk for injury to themselves and patients. Table 3.4 lists some assistive devices found in the hospital and community settings that can be used to help transfer patients in and out of bed and within the bed.
Table 3.4 Assistive Devices to Help Transfer Patients In and Out of Bed and Within the Bed
|Gait belt or transfer belt||Used to ensure a good grip on potentially unstable patients. The device provides added stability when transferring patients. It is a 5 mm (2 in) wide belt, with or without handles, that is placed around a patient’s waist and fastened with Velcro. The gait belt must always be applied on top of clothing or gown to protect the patient’s skin. A gait belt can be used with patients in both one-person or two-person pivot transfer, or in transfer with a slider board.|
|Slider board (stretcher board)||
A slider board is used to transfer immobile patients from one surface to another while the patient is lying supine. The board assists healthcare providers move immobile, bariatric, or complex patients more safely.
|Mechanical lift||A mechanical lift is a hydraulic lift, usually attached to a ceiling, used to move patients who cannot bear weight, who are unpredictable or unreliable, or who have a medical condition that does not allow them to stand or assist with moving.|
|Air transfer mattress||Using air assisted technology, air transfer mattresses allow caregivers to easily reposition and transfer patients laterally (i.e., bed to stretcher and vice versa). See: Product information for HoverMatt Air Transfer System.|
|Slider sheets||Nylon sheets used under the patient. Sometimes the nylon is the undersurface of the transfer sheet. Sometimes a combination of a transfer sheet’s nylon surface in contact with a nylon surface fitted bed sheet can help to reduce friction during patient moves in bed.|
|Monkey bar (a.k.a., medical trapeze)||A trapeze positioned above the patient near the head of the bed allows the patient to grasp and reposition themselves or to help with re-positioning. The trapeze can be fixed to the bed or free standing. They are contraindicated in some situations including new spinal cord injury, post abdominal surgery, and shoulder conditions.|
|Sit to stand lift||Device used to assist patients from a sitting to standing position.|
|Transfer board||Transfer boards (not to be confused with a slider or stretcher board) are small pieces of rigid wood or plastic used to bridge the gap between two surfaces. For example, between a wheelchair and a bed.
When a patient is initially learning to use a transfer board, one to two healthcare workers may use a gait belt to assist. Eventually some patients are able to transfer independently from a wheelchair to bed using a transfer board.

- Use assistive devices only if properly trained in their safe use.
- Always tell patients what you are about to do, and how they should assist you in the procedure.
- Always perform a patient risk assessment or mobility assessment prior to using any assistive devices. The Assessing Risks web page from WorkSafeBC provides additional information regarding assessing risk and resources to help with decisions around safe patient handling.
- Use proper body mechanics when using assistive devices to reduce risk of injury.
Critical Thinking Exercise
- A 100 kg patient with limited mobility requires transfer from his bed to stretcher. The nurse chooses to use a HoverMatt© air transfer mattress for the transfer. Describe how this technology limits musculoskeletal strain, and give the steps for its use in this situation.
