The Effect of Muscle Energy Technique on Pain and Range of Motion in Patient with Knee Osteoarthritis

Abstract

Osteoarthritis (OA) is a progressive degenerative joint disorder characterised by pain, stiffness, and limited range of motion (ROM). According to the World Health Organization (WHO), OA is one of the main causes of decreased quality of human life worldwide. Muscle Energy Technique (MET) is a treatment used to treat OA. This study aimed to determine the effect of MET on pain and ROM in knee OA patients. This research used a type of pra experimental research. The research group consisted of 15 patients with knee OA by purposive sampling who received the MET technique once a week for 4 weeks. Pain was measured by the Numeric Rating Scale (NRS), while a goniometer was used for evaluating the ROM of knee flexion and extension. There was a significant decrease in the average pain score before (4.7/10) and after (3.4/10) MET administration. LGS knee flexion increased by 7 degrees, while LGS knee extension decreased by 1.4 degrees. Statistically, MET positively reduces pain and increases ROM in knee OA (p<0.05). MET is one of the recommended techniques for health workers and physiotherapists in particular, in the management of reducing pain and increasing ROM for patients with knee OA
