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.
Dynamic stretching is a technique used more by athletes. When you perform dynamic stretches, instead of holding the stretch for a period of time, you repeatedly move your joints and muscles through a full range of motion. Dynamic stretches also improve your flexibility and help reduce risk of injury.
