PNF Strategies (Proprioceptive Neuromuscular Facilitation)

Is a method of treating neurological dysfunctions. This approach helped patients become more efficient in their movement and general activities.

There are several techniques to improve efficient recruitment of motor paterns. They are outlined as follows:

• Resistance - Applied to a muscle contraction will facilitate a smooth motor response through optimal muscle contraction and relearning. The type and degree of resistance vary to achieve the appropriate motor response

  
  

• Irradiation - Is the overflow of neuronal excitation from stronger motor units to weaker ones, or units that may be inhibited by injury. This is done by applying graded resistance to larger muscle groups to enhance contraction in the weaker groups

  
  

• Traction - The application of traction perpendicular to the arc of motion is used to facilitate an enhanced motor response

  
  

• Manual Pressure - Neuromuscular responses are influenced by contact with the skin and deeper pressure receptors

  
  

• The stretch reflex - The stretch reflex is a stimulus that increases the state of responsiveness of a motor unit to cortical stimulation. This reflex is sitmulated by the quick elongation of muscle. The stretch stimulates the muscle spindles to create contraction. The muscle spindle and its reflex work as a feedback device that operates to maintain optimal muscle length. The reflex produces a brief isolated contraction

  
  

• Approximation - A compressive force to approximate joint surfaces can facilitate a motor response and promote stability
