본 연구는 만성요통환자에서 PNF 기법을 이용한 요부안정화 운동이 요부 심부근의 두께 변화와 기능적 활동에 미치는 효과를 알아보고자 하였다. 연구대상은 만성 요통환자 30명을 대상으로 하였으며, 실험군을 세군으로 10명씩 무작위 할당하였다; 실험군I은 일반물리치료군(n=10), 실험군II는 일반 요부안정화운동군(n=10), 실험군III은 PNF 기법을 이용한 요부안정화운동군(n=10)으로 나누었다. VAS를 사용하여 통증 변화를 측정하였고, 초음파 장비를 사용하여 4주간의 각 운동에 따른 요부 심부근들(복횡근, 외복사근, 다열근)의 근 두께 변화를 알아보았고, ODQ, RMDQ를 사용하여 기능적 활동 수준 변화를 알아보았다. 그 결과, 실험 전 후에 실험군II와 실험군III의 비교에서 VAS와 근 두께의 변화에 유의한 차이를 보였으며, 각 실험군 간의 유의성 검정 결과, 실험군III에서 다른 군들에 비해 유의한 차이를 나타냈다. ODQ, RMDQ 검사 결과에서는 실험 전 후에 실험군II와 실험군III의 비교에서 유의한 차이를 보였으며, 각 실험군 간의 유의성 검정 결과, 실험군III에서 다른 군들에 비해 유의한 차이를 나타냈다. 이상의 결과로 보아, PNF 기법을 이용한 요부 안정화운동은 일반 요부안정화운동에 비해 통증경감 및 요부에 위치한 심부근들의 두께 향상에 더 효과적임을 알 수 있었으며, 이러한 결과는 기능적 활동수준에도 긍정적인 영향을 미치는 것을 확인할 수 있었다.

Purpose: The purpose of the present study was to compare the effects of proprioceptive neuromuscular facilitation (PNF) and static stretching on weight distribution and flexibility for trunk flexion. Method: Sixty participants who had no musculoskeletal disorders were recruited from a local university within six months of this study. The participants were randomly assigned to a PNF stretching group (N=30) and a static stretching group (N=32). For the pre-and post-measurement design, the left-right weight distribution, anterior-posterior weight distribution, and finger-to-floor distance (FFD) were measured before and after the stretching interventions. Result: The FFD results were significantly improved after the interventions, regardless of the group differentiation (p<0.05). The PNF stretching intervention significantly increased the differences between anterior and posterior weight distribution compared to the static stretching group (p<0.05). Conclusions: Both the PNF and static stretching interventions could improve flexibility for trunk flexion mobility. Although the PNF intervention improved the weight distribution in the anterior-posterior direction, further research is required to investigate the various PNF interventions on left-and-right and anterior-posterior weight distribution.

Purpose : The purpose of this study is to review of effect of the PNF application for improvement of the basic physical fitness in the elderly. Methods : By using internet, we research the PubMed, Science Direct, KISS, DBpia and the article on the effect of PNF. We selected the article between 1970 and 2007. Key words were PNF, Exercise, Elderly. Results : PNF refers to any of several post-isometric relaxation stretching techniques in which a muscle group is passively stretched, then contracts isometrically against resistance while in the stretched position, and then is passively stretched again through the resulting increased range of motion. Most PNF techniques employ isometric agonist contraction/relaxation where the stretched muscles are contracted isometrically and then relaxed. The most common PNF techniques are CR, HR, CRAC, HR-AC, AC. PNF exercise effected on the muscular strength and flexibility and balance and ROM in the elderly. Conclusion : PNF is a safety and effective exercise to improve the muscular strength and flexibility and balance and ROM in the elderly. Therefore, we suggest that PNF need to generalize for the elderly.

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 aims to compare hamstring flexibility and pressure pain threshold (PPT) after an intervention with proprioceptive neuromuscular facilitation contract-relax (PNF CR) technique, myofascial release (MFR), and a massage gun (MG), as well as to verify the effectiveness of the MG. Methods: This study recruited 36 participants (22 males and 14 females) with shortening of less than 70 degrees upon a straight leg raise (SLR) test, and they were randomly assigned to one of the PNF, MG, and MFR groups, each of which underwent its own protocol for 30 minutes. Flexibility of the hamstring was measured after the intervention using the active and passive knee extension (AKE and PKE) test, the sit and reach test, and PPT. Results: The AKE and PKE angles significantly decreased, as well as significantly increased in flexibility when each of the PNF, MFR, and MG interventions was performed (p<0.05). In addition, there was no significant difference among groups. However, according to the Cohen's D effect size, the MG demonstrated the largest effect size in AKE (d = 1.41) and PNF demonstrated the largest effect size in PKE (d = 1.66) and flexibility (d = 0.63). Conclusion: All interventions used in our study are effective in increasing hamstring flexibility. Based on the Cohen's D effect size, an MG is beneficial to increase the AKE, whereas PNF CR technique is recommended for increasing PKE and flexibility.

Purpose: The purpose of this study was to examine the effects of the PNF stabilization technique for the hip joint and the bridging exercise on the trunk stabilizer muscles in healthy adults. Methods: Twenty-eight healthy adults were randomly allocated to either a PNF stabilization exercise group (n = 12) or a bridging exercise group (n = 16). The outcome measures included the contraction thickness ratio in the transversus abdominis (TrA), internal oblique (IO), and external oblique (EO), and the TrA lateral slide was assessed during the abdominal drawing-in maneuver using b-mode ultrasound. The researcher measured the abdominal muscle thickness of each participant before the therapist began the intervention and at the moment that the intervention was applied. Between-group comparisons were performed using the Mann-Whitney U test. The level of statistical significance was set at 0.05. Results: The PNF intervention program showed a significant increase in the trunk stabilizer muscle. The percentage of change in the TrA thickness showed a significant interaction between intervention. However, there were no significant differences in the IO and EO between the two groups. Conclusion: The PNF stabilization technique for the hip joint can be used effectively to improve the IO and TrA muscles in healthy adults.

Purpose: The purpose of this study is to compare the effects of proprioceptive neuromuscular facilitation (PNF) stretching, based on ballistic stretching and the contract-relax technique, on hip joint flexibility and muscle tone in adults with shortened rectus femoris muscles. Methods: The study involved 40 adults with shortened rectus femoris muscles, identified using the modified Thomas test. Participants were randomly divided into two groups: PNF stretching, employing the contract-relax technique, and ballistic stretching. Measurements included muscle tension, hip joint range of motion, and muscle characteristics. The rectus femoris muscle shortening effect was confirmed by the modified Thomas test, while the flexibility effect was assessed through hip joint motion range. The muscle tension effect was determined using Myoton-PRO. Results: Both stretching methods resulted in significant improvements in modified Thomas test angles and frequency, with the PNF stretching group showing notably greater changes. However, neither stretching method significantly affected decrement or stiffness measurements. These findings suggest that PNF stretching may be more effective for certain outcomes compared to ballistic stretching. Conclusion: In summary, both stretching methods positively influenced flexibility and muscle tension, with PNF stretching showing a greater impact. These findings highlight the importance of selecting the appropriate stretching technique for achieving functional improvements in muscles, which could serve as valuable indicators for preventing and treating muscle injuries in both sports and daily activities.
