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.
PNF is considered an optimal stretching method when the aim is to increase range of motion, especially as regards short-term changes.n the early to mid 1900s physiologist Charles Sherrington popularized a model for neuromuscular facilitation and inhibition. This subsequently led Herman Kabat, a neurophysiologist, to develop the clinical PNF stretching technique using natural movement patterns.
