Cushions and seating are powered or non-powered devices placed on a wheelchair or other seating surfaces. They utilize air, fluid, foam, gel, water, wool or a combination of these components to distribute pressure and reduce friction and shear forces.
PNF stands for Proprioceptive Neuromuscular Facilitation. This type of stretching is often referred to as partner stretching because two people are needed to perform the movements. There are many forms of PNF, but most involve an isometric hold followed by a static stretch of the same muscle group.
The most familiar type is static stretching, which requires holding your body still for a set period to elongate the muscle. Active stretching uses a move and hold combination using only the stretched muscle to hold your body position. Dynamic stretching uses a constant series of movements to lengthen the muscle.
