The Meridian Wave LPB Cushionprovides a solid base of support and a high degree of pelvic and lower extremity lateral positioning. Lateral pelvic supports, located posterior to the greater trochanters, provide lateral stability that maintains the pelvis in the center of the seat. Lateral thigh supports position the lower extremities and prevents unwanted abduction of the thighs. The Wave LPB provides a firm foundation for postural stability and discourages chair upholstery from slinging. The closed-cell LPB will not absorb fluid and is resistant to bacteria.
Therapists recommend the Meridian for individuals with motor and neurological dysfunction due to spinal-cord injury, stroke, multiple sclerosis, cerebral palsy, and traumatic brain injury.
Functional areas of the Meridian are created by three types of foam: soft foam for the decubitus-sensitive area of the ITs; medium foam for the thigh trough, pelvic bucketing and pre-ischial bar; and firm foam for the perimeter and medial thigh separator. Valves release air to immerse the user in the foam, which conforms to the user and distributes the user’s weight over the surface of the cushion.
The Varilite Meridian Cushion features dual chambers that allow for independent positioning of the pelvis and thighs quickly and easily. Front and rear chambers permit independent adjustment of the pelvis and thighs, quickly and easily, while the client is seated. The rear chamber allows maximum immersion of the pelvis for better pressure distribution. The front chamber allows maximum loading of the thighs, which reduces pressure on the ITs. The Meridian’s dual-chambered design promotes a neutral pelvis position, especially important for clients prone to extensor tone or thrusting. The thigh and pelvic chambers form a pre-ischial ridge which prevents the ITs from sliding forward, preventing a posterior pelvic tilt and sacral sitting. Releasing more air from the pelvic chamber than the thigh chamber provides added postural support by creating dump or squeeze that “holds” the client in place.
