Flat foot (pes planus) is a common condition characterized by collapse of the medial longitudinal arch, leading to altered plantar pressure distribution, foot fatigue, discomfort, and increased risk of lower-limb musculoskeletal problems. Individuals with flat foot often show increased pressure over the midfoot and medial forefoot, which may affect gait and functional activities.

Physiotherapy interventions such as foot strengthening exercises are commonly used to improve arch support and foot function. Muscle Energy Technique (MET) is a manual therapy approach that aims to improve muscle balance, joint alignment, and neuromuscular control. However, there is limited evidence on the short-term effects of combining MET with strengthening exercises on plantar pressure distribution in individuals with flat foot.

This experimental study aims to evaluate the short-term effects of Muscle Energy Technique combined with targeted foot strengthening exercises on plantar pressure distribution in adults with flat foot. A total of 42 participants aged 18–25 years with diagnosed flat foot will be randomly allocated into two groups. The intervention group will receive MET along with strengthening exercises, while the control group will receive strengthening exercises alone. The intervention will be carried out for four weeks, three sessions per week.

Outcome measures will include plantar pressure distribution assessed using a plantar pressure platform, Foot Function Index, Clarke’s angle, and goniometric assessment. Assessments will be performed at baseline, midpoint (2nd week), and post-intervention (5th week). The results of this study may help determine the effectiveness of combining MET with strengthening exercises in improving plantar pressure distribution and foot function in individuals with flat foot.
