Proprioceptive Neuromuscular Facilitation technique is based on the combination of passive stretching and muscle contraction. It stimulate the sensory receptors, due to the stimulation it helps to control the motor function of the body. - Increase flexibility and muscle strength, enhance facilitate movement pattern , improves the coordination and range of motion Studies have found that doing PNF stretches before exercise can increase performance in exercises such as jogging. PNF was first used to help people with neurological conditions, but it can also treat musculoskeletal conditions. Now, the concept is used for rehabilitation. PNF can help increase your range of motion (ROM) after an injury or surgery PNF technique in the geriatric fitness to enhance the flexibility, coordination and also for the muscle function.
