The perception seat for dynamic seating

Seating system TWIST EASyS Wing suspension Flexible wing suspensions adapt to the body contour and absorb the slightest moving impulses of the body to emit them after as sensory stimulus. Each wing suspension can be moved or taken out to ensure an individual adjustment. Spring element The moveable spring elements offer diverse movement to the child but always gently guide it back into the starting position. The single spring elements can be adjusted by 2 cm / 0.79" in depth and can also be tilted. This enables an individual setting for the iliac crest straightening or lumbar support. Spring...

T^|£>T ... is a perceptual concept for dynamic seating, which is based on the active principle of Micro-Stimulation®. It is designed to assist and support the child's development of spatial awareness. The flexible spring elements and wing suspensions of the seat, activate and support the individual movement of the child and therefore help improve their cognitive and emotional development.

Work principles MiS Micro-Stimulation® when sitting down Work principle of impulse processing Dr. h.c. Berta Bobath and Dr. Karel Bobath already discovered that movement, posture and other activities of the body are dependent on external stimulation. A sensory impulse of any kind is assimilated by the human body as a kind of input. After reception this impulse is converted and processed to exit, so called output. This output expresses itself in a particular movement, a posture or even a noise or specific words. People are dependent on impulses from their environment to interact with it!...

The basic principle of the TWIST EASyS perception seat is to give the children a sensory impulse with help of the MiS wing suspensions. The system absorbs the slightest movements of the body and emits them elsewhere through an impulse. This is how on the one hand an impulse-reaction-chain is started and on the other hand movement is possible without loss of stability. We all know about the concurrent relaxing and activating effect of sensory stimulation. TWISTEASyS spring element

Work principles MiS Micro-Stimulation® when sitting down TWIST EASyS activates the children again and again to carry out little micro movements. These movements are tolerated by the seat unit without taking away the safety of a supporting seat unit. The human organism possesses a sophisticated protection system, which prevents him from overloading single muscles or muscle groups partially. We recognise this e.g. when changing from one leg to the other to spread our weight when standing up without being aware of it. With children this „urge of movement“ is even more distinctive. They need...

Case study Argentina Age: 3 years Diagnosis: cerebral moving malfunction with significant torso hypotony and heavy amplyopia Without butterfly / chest harness Argentina moves her upper part of the body forward and displays a big arched kyphosis of the spine. The lateral trunk supports restrict her moving abilities and ensure a symmetric seating position. Because of the belt thickness the moving facilities with the arms are limited. To straighten up Argentina is constantly dependent on the inflexible butterfly / chest harness belt. When fastened with a butterfly / chest harness there is...

TWIST EASyS RECOMMENDATION: The more support the child needs the higher the impulse generators should be adjusted to the torso. However, there have to be at least 2 fingers space under the armpits to prevent pressure on important vasculars and nerves. Impulse generatorsMiS Micro-Stimulation® for sitting wants to help children with special needs to stabilise without loosing all moving facilities.TWIST EASyS Impulse generators The round TWIST EASyS impulse generators are sitting closely on the sides of the child's torso. The support joins two glass fibre profiles together and makes the system...

Inflexible belts should be applied only in rigid seating systems. To support the MiS Micro-Stimulation® all positioning components should be as flexible as possible. Flexible TWIST EASyS belts With a flexible, micro-stimulating back system it makes sense to combine it also with a flexible belt system. In the pelvis area however firm support is essential as especially children with spastic moving patterns have to be positioned in this area with considerable resistance. The upper part of the body however can easily move in the TWIST EASyS perception seat with MiS wing suspensions and...

RECOMMENDATION: A basic principle in the health care for children should be: „ Children receive as much sitting support as necessary but as little as possible!" This means the provision should be carried out according to the „Bottom-Up-Idea", rather than the „Top-Down"! Positioning in TWIST EASyS Recommendations for positioning in a TWIST EASyS perception seat: The TWIST EASyS perception seat is characterised by a flexible back system and a firm seating area. The open design of the back system makes it possible to monitor and examine the posture of the child during positioning. This is a...

Positioning in TWIST EASyS What is special about the TWIST EASyS perception seat: O The spring elements affect the positioning in the pelvis as well as in the whole back area without resulting in a complete stiffness. e The bottom spring element can be used to support an iliac crest straightening. The upper elements can constitutively be adjusted to the shape of the spine, and by that they support the lumbar spine area. Slightest movements from this individual position for the child are possible but it will always be gently guided back in the starting position. RECOMMENDATION: With help of...

Adjustment TWIST EASyS First step First step First the footrest, seat depth and seat width have to be adjusted. In this way a good starting position can be achieved from which further individual settings can be carried out. Second step Second step A suitable hip angle has to be set. Afterwards, the back height can be adjusted. It is possible that for this setting a complete spring element (FGF-track) has to be removed. In order to do this, please remove the element completely with help of the big screw positioned in the middle of the back part. The headrest can now be set ergonomically to...
