The Effect of Radiofrequency of 448 kHz on Pain and Function

The goal of this trial is to compare the effects 448kHz capacitive resistive monopolar radiofrequency (CRM) with Proprioceptive Neuromuscular Facilitation (PNF) versus only PNF in chronic low back pain patients.The main questions it aims to answer are:Is there any difference in interventions on reduction of pain.Is there any difference in interventions on reduction of disability.Participants will in the experimental group will be treated with a combination of:448kHz capacitive resistive monopolar radiofrequency and,PNF interventionParticipants will in the control group will be treated only using1. PNF intervention (identical to experimental group)Researchers will compare experimental and control group to see if there are differences in reduction of pain and disability.

Inclusion Criteria:older than 18 years, chronic low back pain (CLBP)Exclusion Criteria:spinal fractures, radiculopathies, history of spinal surgery, spinal stenosis, history of thrombosis, pacemaker, pregnancy
