Study summary

Therapeutic options for SIJ pain include intra-articular corticosteroid injections, which provide symptomatic relief but typically require repeated administration due to variable and short-lived efficacy.

More recently, pulsed radiofrequency (PRF) has been investigated for joint pain management through intra-articular electrode placement and stimulation. However, its effectiveness in treating SIJ pain remains insufficiently studied and warrants further exploration.
