Purpose: This study compared and analyzed the effect of the proprioceptive neuromuscular facilitation (PNF) arm extension pattern and leg flexion pattern on the contralateral lower extremity muscles when the patterns were applied to the same subject. Methods: In the study, 35 healthy men and women who understood the PNF patterns were selected as participants. The participants completed the PNF arm extension-abduction-internal rotation pattern and leg flexion-adduction-external rotation with knee flexion pattern in the supine position. While the patients' completed each pattern, the contralateral leg muscle activity was measured to examine the irradiation effect. The maximum isometric contraction time of the muscles to be measured was kept for 5 seconds, and the mean value was obtained by repeating the pattern three times. Results: When the leg flexion-adduction-external rotation with knee flexion pattern was completed, the muscle activity in the vastus lateralis, vastus medialis, biceps femoris, tibialis anterior, and gastrocnemius of the contralateral lower extremity was significantly greater than that found in the PNF arm extension-abduction-internal rotation pattern. Conclusion: The PNF leg flexion pattern showed greater muscle activity on the contralateral lower extremity than the arm extension pattern. Thus, the PNF leg extension pattern is more effective in the activation of the muscles associated with weight-bearing activity.

Purpose : The purpose of study was aimed to identify whether the painless dynamic PNF techniques makes any differences in reducing lymphedema by applying this technique to lymphedema patients, and to provide the basic reference data for the purpose of applying to lymphedema patients. Methods : A total of 40 women participated in this study, and they did PNF techniques before applying lymph compression bandages. Group 1 of 20 subjects performed PNF techniques three times a week with 30 minutes each time. Group 2 of 20 subjects only practiced edema reducing massaging for 30 minutes. Results : In addition, the interaction between treatment method and treatment time was significant (p<.0001), which indicates that the changes in edema rates by measurement times appear differently according to treatment methods. In this study, it means that the 'PNF techniques' group has a steeper slope of decline than the 'message' group. Conclusion : In conclusion, both massaging and PNF techniques helped to lower edema rates. Four weeks after the beginning of treatment, PNF techniques was exhibited as generating a large degree of decline in edema rates than massaging.

Purpose: This study aimed to determine the most effective way to facilitate the abductor hallucis muscle during PNF leg pattern-emphasized hallux abduction. Methods: The study recruited 18 healthy adults. All participants agreed voluntarily to take part in the study following an explanations of its purpose and procedures. They randomly performed the PNF leg pattern-emphasized hallux abduction variations in a hook-lying or sitting position. Activation of the abductor hallucis (AbH), adductor hallucis (AdH), extensor hallucis longus (EHL), and tibialis anterior (TA) muscles, and the ratio of AbH/AdH, were measured during PNF exercises using electromyography. One-way repeated ANOVA was used to compare the activation of foot intrinsic and extrinsic muscles during the four PNF exercises. Results: PNF leg pattern-emphasized hallux abduction using normal timing was significantly higher in TA compared to PNF leg pattern-emphasized hallux abduction using timing for emphasis, regardless of the starting position. The PNF leg pattern-emphasized hallux abduction using timing for emphasis in the hook-lying position was significantly higher in AbH than in other exercises. Although there was no statistically significant difference in the ratio of AbH/AdH, it was higher in the hook-lying position. Conclusion: PNF leg pattern-emphasized hallux abduction using timing for emphasis in the hook-lying position can be recommended as a method to optimize the activation of AbH and the ratio of AbH/AdH.
