For those who have limited ability to make small changes in movement, it is important to consider dynamic seating. Dynamic seating has a range of adjustments to tailor the chair to the user’s physical requirements to prevent the user becoming fixed in the same shape as the chair they are using. Combining the appropriate functionality and features enables posture and body weight to be adjusted throughout the day to prevent pressure build up in isolated areas.
Pressure relief characteristics within seating can considerably reduce the effects of friction, shearing and body weight upon skin and muscle tissue. Distributing body weight over a larger surface area will help reduce pressure however the use of special pressure relieving cushions and foams can help prevent the development of pressure ulcers. The inclusion of tilt-in-space is also excellent for redistributing and changing pressure points. Click here for further information on pressure care management.
Upholstery has great significance on the properties of a chair. Body temperature, perspiration and tactile response are dependent on the finish and quality of the material used to upholster the chair not forgetting other important factors including durability and wear.
Tilt-in-Space enables the occupant to be tilted forward or backwards in a chair whilst maintaining the position of the knees and hips to achieve a resting position. By keeping the angle between the chair seat and back at around 110⁰, the occupant will not slide forwards into an uncomfortable, slumped position. Tilting the body has the effect of distributing weight over a larger contact surface area providing a simple and effective way to combat the build up of pressure.
Back angle recline traditionally has facilitated a resting or napping position and is suitable for those who are able to maintain their position independently. However, for those less able to sustain pelvic stability, back angle recline in conjunction with an angled or ramped seat enables the benefit of a resting position to be realised.
Achieving the correct seat height for the user allows the feet to be positioned firmly on the floor or footboard to ensure even weight distribution and assist the ambulant user to stand from the chair more readily.
An elevating footrest or legrest can assist with the lymphatic and blood circulation. Lifting and straightening the knees has the effect of allowing the blood to circulate more freely, reducing the effort required by the heart and arterial systems. Raising the legs can also help alleviate leg oedema, a build up of fluid in the legs.
An arcing legrest extends forward as it elevates and is ideal for chairs with footboards as it maintains the positioning of the footboard and comfort for the user in both the raised or lowered position. This is especially important where the occupant is able to independently adjust the legrest positioning and there is then no requirement for a carer to reposition the footboard.
Raise facilities on our Fitform range of riser recliner chairs gently lift individuals to a standing position without placing significant pressure on limbs and joints. Stability and positioning is maintained by ensuring the feet remain close to the floor.
Functionality Options for Dynamic Seating
Manual adjustment enables fluid and precise movement of the tilt-in-space facility or back angle recline by the release of a gas action mechlock lever situated on the push handle.
Manual tilt-in-space or back angle recline gently moves back and forth as directed by the carer with minimal effort whilst the legrest can be elevated by a separate release mechanism at the front of the chair. The legrest gently raises or lowers accordingly guided by the carer to attain the appropriate position.
Electric adjustment enables the carer or user, where appropriate, to adjust the tilt-in-space or back recline facility and/or the legrest by the simple touch of a button providing an electrically powered motion to these mechanisms.
Utilising an undemanding hand controller, the movement of the chair’s electric adjustments is smooth and gentle reducing the effort whilst increasing the positioning range and flexibility of the chair.
Regulated Motion has been incorporated into the Delta and Duo designs (with the exception of the Duo Mini) to create the ultimate pressure management chair as well as a source for proprioceptive and kinaesthetic input for those whose condition means they are largely immobile.
The combination of low interface pressures on the head, shoulders, arms, legs and ankles is achieved using Reflexion™ foam alongside the appropriate pressure relieving seat cushion. A correctly dimensioned tilt-in-space chair with arcing legrest elevation and the ability to “regulate the motion” or movement of the chair provides the user with pressure management through dynamic movement.
A six-buttoned hand controller is programmed to ensure the tilt- in-space has “Regulated Motion” or the ability to move over a set range automatically adjusting the tilt positioning. The pattern of movement is set to repeat to ensure motion over a period of time within a specified tilt range.
Regulated Motion ensures that pressure points on the body are in continuous flux. This enables the carers and the user who may be sitting in the chair for long periods, to sleep with the secure knowledge that dynamic movement will be at work continuously changing the pressure hotspots. It will reduce the propensity for pressure related problems and improve the comfort and sitting experience. Also carers will not be burdened with the expectation of 20 to 30 minute position changes.
Underpinned by the sound understanding and importance of dynamic movement in pressure management through alternating pressure relief seats and mattresses, Regulated Motion in seating has the power and simplicity to become an accepted and intrinsic part of pressure management solutions.
