어깨충돌증후군 환자의 어깨 기능, 봉우리-위팔뼈 간격, 압력 통증 역치에 대한 PNF와 관절가동술의 효과 비교 -무작위 대조 연구- = Effects of PNF and Joint Mobilization on Shoulder Function, Acromiohumeral Distance, and Pressure Pain Threshold in Patients With Shoulder Impingement Syndrome: A Randomized Controlled Trial

다국어 초록 (Multilingual Abstract)

Purpose: This study aimed to compare the effects of proprioceptive neuromuscular facilitation (PNF) and joint mobilization (JM) on shoulder function, acromiohumeral distance (AHD), and pressure pain threshold (PPT) in patients with shoulder impingement syndrome (SIS). Methods: Thirty patients diagnosed with SIS were randomly assigned to either a PNF group (n = 15) or a JM group (n = 15). Both groups received conventional rehabilitation with additional PNF or JM techniques for 6 weeks (3 sessions/week). Shoulder function was assessed using the Shoulder Pain and Disability Index (SPADI), structural changes were measured via AHD, and pain sensitivity was evaluated using PPT. Two-way repeated-measures ANOVA with post-hoc analyses was performed. Results: Both interventions significantly improved all outcome measures. The PNF group demonstrated superior improvements in SPADI (p < 0.05) and PPT (p < 0.05), indicating enhanced functional recovery and reduced pain sensitivity. The JM group showed greater increases in AHD, suggesting more effective subacromial space restoration. Significant group × time interactions were observed for SPADI and PPT. Conclusion: Both PNF and JM were effective for SIS management, with distinct therapeutic advantages. PNF showed superior effects on functional recovery and pain modulation, while JM was more effective for structural space restoration. †Corresponding Author : Dae-Jung Yang ([e-mail]) PNF and Movement, 2026; 24(1): 101-111 https://doi.org/10.21598/JKPNFA.2026.24.1.101 Print ISSN: 2508-6227 Online ISSN: 2508-6472 Original Article Open Access 어깨충돌증후군 환자의 어깨 기능, 봉우리-위팔뼈 간격, 압력 통증 역치에 대한 PNF와 관절가동술의 효과 비교 -무작위 대조 연구- 이형석1⋅양대중2† 1세한대학교 대학원 물리치료학과, 2세한대학교 물리치료학과 Effects of PNF and Joint Mobilization on Shoulder Function, Acromiohumeral Distance, and Pressure Pain Threshold in Patients With Shoulder Impingement Syndrome: A Randomized Controlled Trial Hyung-Seok Lee, P.T., M.Sc.1⋅Dae-Jung Yang, P.T., Ph.D.2† 1Department of Physical Therapy, Graduate School, Sehan University 2Department of Physical Therapy, Sehan University Received: November 19, 2025 / Revised: December 30, 2025 / Accepted: January 05, 2026 ⓒ 2026 Journal of Korea Proprioceptive Neuromuscular Facilitation Association This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. 102 | PNF and Movement Vol. 24, No. 1 These findings suggest that intervention selection should be guided by individual patient impairment profiles. Future multi-center studies with larger samples and longer follow-up periods are needed to establish optimal treatment protocols.
