One 2015 review suggests massage can provide short-term pain relief in people with musculoskeletal pain. The review also found massage helped relieve pain, compared with no treatment. However, researchers note the studies in the systematic review only provided low or moderate-quality evidence. Some rollers are padded and can, occasionally, be left in position under the person; others are very thin and are nearly always removed after use. If a roller is left in position it is important to ensure the person will not accidentally slip out of bed.

The pros of this product are its three massage zones, four traveling deep kneading massage nodes, heat with an automatic “off” to prevent overheating, and its easy portability. Lifting poles are not usually suitable for people with painful arms, painful shoulders, limited overhead shoulder movement or abdominal weakness. However, a unique model is available which serves as a safety rail, can be used independently and also helps raise the person’s legs. An air filled platform first moves through 90° to bring the platform to the horizontal, lifting his/her legs. The user then moves the legs across into bed. The platform can be raised a further 90° to form a barrier to prevent him/her falling out of bed.These are made of a length of material which has either been stitched to form a continuous roller or is folded in a similar way so that the slippery material on the surfaces inside will easily slide against each other.

The seat area of the massage cushion can vibrate at three different speeds. The heat option warms the shiatsu balls, which Snailax claims increases circulation and helps muscles relax.
