Back Angle Recline (BAR) adjusts the angle between the chair seat and back, which has an effect on hip angle. BAR is useful for creating a comfortable hip position. It can be adjusted to improve comfort if a user has problems with dislocated or injured hips, to relieve abdominal pressure if they have a pronounced stomach, or to relieve hamstring tension if the legrest is elevated.
Tilt-in-Space (TiS) allows you to change the reclining angle of the chair seat and back without adjusting the user's hip and knee angle. Our experience is that even a 20° tilt can reduce interface pressure under the buttocks and thighs. The less mobile the user, the more frequently TiS should be used to redistribute their body weight and to help them combat fatigue. TiS can also be used to reposition a user from upright for activity and eating, and to recline for resting.
Legrest elevation can be used to lift a user's lower legs to provide a relaxing position. It encourages blood circulation and may reduce leg pain and swelling. Raising the legs above hip level for 30 minutes three or four times a day can help swelling to subside and significantly improve circulation. You may find that using TiS and legrest elevation in combination to raise the lower leg higher than the hips is more comfortable than elevating the legs with the knees fully extended. The articulating legrest has a mechanism that brings the legrest up and out, making sure that support is consistent through the full range of movement.
The main difference between BAR and TiS is the effect they have: BAR opens the hip angle, while TiS allows the user to recline without affecting their hip and knee angles. Both features have an effect on the user's ability to maintain their position in the chair. As the back is reclined, the tendency is for the user to slide forwards in the seat. As a general rule, if you are using BAR, use TiS simultaneously. Tilting the seat unit back as hip angle is opened up will help maintain stability. Alternatively, choose a CareFlex chair with a seat unit that can be set at different angles and then adjust the BAR for different activities and to maximise comfort.
Manual actuation allows CareFlex chairs to be adjusted manually with the minimum mechanical help. A carer or health professional can easily control the movement of TiS, BAR and legrest elevation, but some skill is needed to balance all elements together. In multi-user care environments, manual actuation is a very cost effective, low-maintenance way of adjusting the position of users in their chairs.
Motorised actuation can increase independence and help carers with repositioning especially when moving and handling heavier people. An electrically powered system, controlled by either the user or the carer, means that the legrest, TiS or BAR can be adjusted quickly and easily. Motorised actuation uses a battery system – if the chair is moved around, the system keeps working. It's a useful aid to independence, giving people the ability to fine-tune their position according to their preferences.
AutoTilt enhances the standard pressure management features already built into the HydroTilt and HydroFlex, and reduces the time needed for manual repositioning. Two microprocessors move the chair through 0.5° of travel at short intervals just enough to refocus the pressure points on the body. The AutoTilt cycle starts from a seating angle of 20°, moving through 12° in eight minutes, gently tilting the chair back and returning over the same period of time to its starting position. AutoTilt can be programmed to repeat this cycle for 1 or 8 hours, ensuring optimal pressure care for those that need it most.
All CareFlex chairs provide soft tissue management through well-fitting chairs that incorporate specially designed pressure relief materials as standard. Go to our page on CareFlex WaterCell Technology® to find out more.
Pro-Control is a motorised actuation system which allows users to adjust TiS and legrest elevation, and the movement options we want to encourage use of, without changing hip angle and risking instability. BAR is manually controlled with a small, hidden lever. This means that once the hip angle has been adjusted, there is no chance of destabilisation by any inadvertent movement of the back. If this feature is required, simply select the Pro-Control HydroFlex.
