ABSTRACT Background: The plantar fascia develops a degenerative disease called plantar fasciitis. The most prevalent cause of inflammation in the inferior heel is plantar fasciitis. Excessive stretching can develop plantar fasciitis, an inflammatory disorder of the plantar fascia that can cause ripping and inflammation of the fascia. Plantar fasciitis is considered the etiology of 11% to 15% of foot complaints that need medical attention. Plantar fasciitis affects two million people, resulting in one million outpatient visits per year. The aim of this study is to find out the effect of Muscle Energy Technique versus Conventional exercise on pain and functional outcome in subjects with Plantar Fasciitis. Methods: Subjects with plantar fasciitis were included based on the selection criteria. The plantar fasciitis pain/disability scale was used to calculate pre and post-test results. The subjects were randomly assigned into, Muscle Energy Technique group (n=30) followed by post isometric relaxation and reciprocal inhibition and received muscle energy technique and to Conventional exercise group(n=30) received stretching of calf muscle and plantar fascia and strengthening the intrinsic foot muscles followed by ultrasound for 15 minutes. Result: According to the statistical analysis, both groups had a statistically significant improvement between their pre and post values (p<0.0001). There was significant variation in postexercise results between the two groups (p<0.0001), indicating that muscle energy technique is more effective than conventional exercise. Conclusion: Muscle energy technique has been shown to be more effective than Conventional exercise at relieving pain and improving functional outcome.
