PNF – proprioceptive neuromuscular facilitation
In addition to using specific patterns of movement, PNF also utilizes several techniques to facilitate movement. Manual contact, appropriate resistance, verbal commands, vision and timing are some of the basic techniques, while rhythmic stabilization, combination of isotonics (a combination of eccentric and concentric muscular contractions) and the contract-relax method are some special, more functionally-based techniques.
PNF uses the body’s proprioceptive system to facilitate or inhibit muscle contraction. One of the pioneers in the use of PNF, Dorothy Voss, defined it as a method of promoting or hastening the response of the neuromuscular mechanism through the stimulation of proprioceptors.1 The muscles must work synergistically in order for movement to occur. This requires the muscles to have the reflexive ability to contract and relax in order to perform basic movements. Fundamental movements such as squatting, lunging and stepping are PNF patterns that all rely on the body’s ability to effectively create and control mobility and stability. When these movements become dysfunctional, it can often be traced to a disruption in the body’s proprioceptive system, leading muscles to either be inhibited or not facilitated at the right moments. This causes an inability to create the balance of mobility and stability, improving this balance is the basis of functional training.
Empley and Semont maneuvers
The Epley and Semont maneuvers are exercises used to treat benign paroxysmal positional vertigo (BPPV). They are done with the assistance of a doctor or physical therapist. A single 10- to 15-minute session usually is all that is needed.
When your head is firmly moved into different positions, the calcium crystal (canalith) debris causing vertigo will slip out of the semicircular canal into an area of the inner ear where it will no longer cause symptoms. Two maneuvers have been used successfully: the Epley maneuver and the Semont maneuver.
