Purpose: This study examined whether a single application of a lumbar flexion muscle energy technique (MET) could significantly influence pain, functional status, and range of motion in chronic back pain patients with restricted active trunk flexion.
Methods: Twenty volunteers were randomly assigned to either a control group or an experimental group. Ten subjects in the control group received no treatment. Ten subjects in the experimental group received five sessions with the muscle energy technique, five times per week for two weeks. Outcomes were measured before and after two weeks of treatment in both groups. Pain intensity was assessed using a visual analogue scale (VAS). Range of motion was measured using the sit-and-reach test (SRT). Functional disability levels were assessed using the Korean version of the Oswestry Disability Index (KODI).
Results: The experimental group showed a significant difference in VAS, KODI, and SRT between pre- and post-treatment (p < .05), while the control group showed no significant changes. The changes in VAS, ODI, and SRT were statistically significant between the groups pre- and post-treatment (p < .05).
Conclusion: This muscle energy technique is clinically effective for chronic low back pain patients.
