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 proper way to perform an isometric stretch is as follows: 1  Assume the position of a passive stretch for the desired muscle. 2  Next, tense the stretched muscle for 7-15 seconds (resisting against some force that will not move, like the floor or a partner). 3  Finally, relax the muscle for at least 20 seconds.
