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.
Static stretching is simply the opposite of dynamic stretching. The muscle groups are stretched without moving the limb itself and the end position is held for up to 30 seconds (1,2) Static active stretching requires the strength of the opposing muscle groups to hold the limb in position for the stretch. For example, standing on one leg and holding the opposite leg out directly in front of you is classed as a static active stretch. The quadriceps actively hold the stretched limb.
