Comparison of Effects for Application of Proprioceptive Neuromuscular Facilitation Technique and Static Stretching on the Calf Muscle

The purpose of this study was to compare the effects of one proprioceptive neuromuscular facilitation technique and static stretching on calf muscle tightness. The subjects consist of 9 hemiplegics, and 9 quadriplegics. The eighteen subjects were randomly divided into 3 groups: prorioceptive neuromuscular facilitation(6 persons), static stretching(6 persons) and control(6 persons). Contract relax antagonist contract and static stretching techniques were applied continuously for twenty minutes each. Of the many proprioceptive neuromuscular facilitation techniques, only the contract relax antagonist contract technique was applied. The static stretching technique was applied with the subject placed in standing on a seventy degree inclined tilt table for twenty minutes. A wedge was placed under the feet to obtain maximum dorsiflexion. Wedge thickness varied with each subject. Results revealed: (1) a significant difference between the experimental and the control groups(P<0.05). (2) a significant difference between contract relax antagonist contract and static stretching groups(P<0.05). (3) At day five, the final increments were: contract relax antagonist contract 11.9±1.9°, static stretching 7.7±2.3°(mean±standard deviation).
