Objective: This study aimed to investigate the effects of a 6-week proprioceptive neuromuscular facilitation (PNF) stretching on pain, proprioception, joint range of motion (ROM), and joint moments during stair ascending among older adults with knee osteoarthritis (KOA). Design: This study is a randomized, controlled, and assessor-blinded trial. Thirty-six older adults with KOA were randomly assigned to the PNF and the control groups. They received PNF stretching and health lecture series, respectively, for 6 weeks. Final data analysis included 14 participants of the PNF group and 13 of the control group. Pain score, joint proprioception, ROM, and joint moments during stair ascending were measured before and after the stretching. Two-way (group by time) ANOVA with repeated measures was used to evaluate stretching effects. Results: Significant interactions were detected in pain score, joint proprioception, external knee adduction moment (eKAM), and external knee extension moment (eKEM). Compared to week 0, the pain score, joint proprioception threshold, and eKAM decreased, while the eKEM increased among older adults in the PNF group at week 7. Conclusion: PNF could be recommended as one of the clinical treatments for KOA to relieve pain, improve proprioception, and balance load distribution between medial and lateral compartments at the knee.
