Pengaruh latihan pnf terhadap fungsi neuromuskular pada rehabilitasi osteoarthritis lutut: Tinjauan literatur

Knee osteoarthritis is a degenerative joint disorder commonly associated with chronic pain, impaired proprioception, muscle weakness, and reduced neuromuscular control, all of which may contribute to functional limitations and reduced quality of life. Beyond structural joint damage, neuromuscular dysfunction is an important target in non-pharmacological rehabilitation. Proprioceptive Neuromuscular Facilitation (PNF) is a therapeutic exercise approach that combines proprioceptive stimulation, muscle activation, stretching, and functional movement patterns to support neuromuscular coordination. This narrative review aimed to evaluate the effects of PNF training on neuromuscular function in patients with knee osteoarthritis. Literature was searched in PubMed and Google Scholar using combinations of terms related to PNF, knee osteoarthritis, neuromuscular function, proprioception, postural balance, and rehabilitation. Studies involving human participants with knee osteoarthritis, PNF-based interventions, and relevant clinical or functional outcomes were considered. Eight primary studies were identified for the narrative synthesis. Overall, the available evidence generally indicates that PNF-based interventions may reduce pain and improve muscle flexibility, postural balance, muscle strength, range of motion, and knee-related function. However, the studies varied in design, PNF technique, comparator, intervention duration, and outcome measures, limiting direct comparison and preventing quantitative pooling. PNF may therefore be considered as one component of a multimodal rehabilitation program, while better-standardized randomized studies with longer follow-up are needed to strengthen the evidence base.
