Objective: This study aimed to observe the influence of two manual techniques in improving the flexibility of the triceps surae muscle in working females wearing high heels. Methods: This study is based on a pretest-posttest experimental control group design, which included forty-five working females wearing high heels. All the participants were assigned randomly into three groups A, B and C. Group A received a hot pack treatment for 20 minutes followed by a Muscle Energy Technique (MET) which was repeated four times (10-second contraction, 5-second relaxation). Group B received a hot pack intervention for 20 minutes followed by static stretching which was repeated five times (30-second hold, 15-second rest between each repetition). Group C received only a hot pack intervention for 20 minutes. Active ankle dorsiflexion range of motion (ADFROM) on day 1 pre-intervention (baseline) and post-intervention on Day 1, 3, 5 and 8 was taken as an outcome measure. Results: For the variable ADFROM, the data analysis showed insignificant differences (p0.05) against control group C, though an insignificant difference (p__ampersandsignlt;0.05) between them at Day 5 post-intervention and the Day 8 follow-up, respectively. Conclusion: This study concluded that both manual techniques are equally effective in improving the flexibility of the triceps surae muscle in working females wearing high heels.
