This study aims to examine the effects of a12-week Proprioceptive neuromuscular facilitation (PNF) intervention on pain relief, passive and active joint ROM, external knee adduction moment (KAM) and hip adduction moment (HAM) in the elderly with Knee osteoarthritis (KOA) during stair descent. Seventy-six elderly who were diagnosed with KOA were recruited and randomly divided into two groups: the twelve-week PNF intervention group and the control group. Pain score was measured by the Western Ontario and McMaster Universities Arthritis Index (WOMAC). KAM, and HAM during stair descent were measured using a motion analysis system with a force platform. All the data were recorded at weeks 0, 6, and 12. Compared to the control group, the PNF group showed a decreased pain score, increased HAM during stair descent. PNF intervention is a successful method to relieve symptoms of KOA. It relieves pain without increasing KAM, enhances passive ROM, increases active knee flexion ROM, and increases HAM during stair descent in the elderly with KOA.
