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.
Stretching can generally be divided into two types: static and dynamic stretching. Static stretching involves moving a joint to the end of its ROM and holding this stretched position for a set period of time. On the other hand, dynamic stretching involves controlled movements through the active ROM for a joint.
