Leg lifter strap: how long it should be and how to use it

What a leg lifter does and who it helps

A leg lifter is a long strap with a foot loop at one end and a hand loop at the other. You hook your foot, then use your arms to guide the leg where it needs to go. The effort moves from the hip and thigh to the hands and shoulders.

People use one after hip or knee surgery, with a leg cast, or when a leg is weak or stiff for other reasons. It can also spare a caregiver from lifting the leg by hand.

It moves the leg; it does not support the body. It does not replace a transfer belt, a grab handle or a second person when those are needed.

• Lifting a leg onto the bed when getting in at night
• Swinging legs into a car seat from a standing turn
• Moving a foot onto a wheelchair footrest or recliner footrest
• Shifting a leg in bed without bending forward

Rigid or soft leg lifter strap: which type?

Rigid leg lifters have a metal rod sewn along the strap. The rod keeps the foot loop open, so you can hook a foot without bending forward, and it lets you push the leg as well as pull it. Both Vive and Sammons Preston describe this design.

Soft webbing straps fold small and suit travel, or a user who only needs a little help. Their loop can flop closed, which makes hooking the foot harder from a seated position.

Whichever type you choose, check the loop against your bulkiest shoe or cast. Sammons Preston notes its rigid foot loop can be pre-bent to fit the width of a cast.

• Hand loop: wide enough for a relaxed grip, not a tight pinch
• Smooth nylon wipes clean and slides over bedding

How long should a leg lifter be? A seated-reach check

Length decides whether you can sit upright while lifting. Too short and you lean forward to reach the hand loop, which hip precautions often ask you to avoid. Too long and the strap is harder to control.

Makers publish a range, shown in the table. No listing can know your reach, so check it at home before ordering.

Sit upright on the edge of the bed you use, foot flat on the floor. Have a helper run a tape measure from under your heel to your hand held at about lower-chest height, elbow relaxed. Compare that figure with the strap's listed length.

• Measure on the bed or chair you will use most
• Wear the shoe, slipper or cast you will use
• Choose a strap at or slightly above your measurement
• Ask your therapist to confirm the length after surgery

Using the strap for bed, chair and car

The basic method is the same everywhere: sit first, hook the foot, then lift with your arms as you turn your body. Ask your therapist to show you before you go home, because they set your limits on bending, turning and weight bearing.

MedlinePlus hip care guidance tells people not to cross their legs or bend far forward from the waist, and to use helpful devices so they do not bend too much. Its home setup guidance suggests a bed low enough that your feet touch the floor when you sit on the edge.

In a car, sit down with your back to the seat first, then bring one leg in at a time if your therapist agrees. Keep the strap clear of the pedals.

• Sit on the bed edge and slide the loop over your foot
• Hold the hand loop with your back upright
• Lift the leg as you turn and scoot back onto the bed
• Lower the leg gently, then slip the loop off
• Stop and ask if a movement causes new or sharp pain

Leg lifter straps compared

We could confirm one leg lifter whose Amazon listing matches the maker's product page: the Vive Leg Lift Assist. The facts below come from Vive's page and the listing title; we have not tested it. Unbranded straps without a checkable maker page are left out.

The Sammons Preston figures are a length reference from that maker's page, so you can see how a shorter strap compares. Keep the packaging until the strap works in your own bed and car.

Common mistakes and when to ask for help

The most common mistake is buying by price instead of seated reach, then leaning forward to use a strap that is too short. The second is using it in a way your care team has not cleared, such as pulling the leg across the body after hip surgery.

Setting matters too. A strap is harder to use on a very soft or very high bed, or in a low car seat. If you cannot move the leg even with the strap, or a caregiver is straining, ask an occupational therapist about other transfer aids.

• Choosing a length without a seated-reach check
• Pulling the leg across the body without advice
• Leaving the strap out of reach of the bed
• Using a frayed strap or one with a bent rod
• Carrying on when a helper strains to lift
