Abstract	Prader-Willi Syndrome (PWS) is a rare and complex multisystem genetic disorder, recognized as the most common genetic cause of life-threatening obesity in humans. It is an imprinted neurobehavioral condition affecting multiple organ systems and arises from the lack of expression of paternally inherited genes on chromosome 15q11-q13. One of the frequent musculoskeletal issues in PWS is deformity of the medial longitudinal arch, which may present as either excessively high (cavus foot) or low (flat foot), significantly impacting foot function and increasing the risk of secondary musculoskeletal problems. Short-foot exercises (SFE) are commonly recommended to strengthen intrinsic foot muscles, particularly the Abductor hallucis, and to maintain or improve the height of the medial longitudinal arch. OBJECTIVE The objective of the study is to find the effect of short foot exercise on foot arch index and gait efficiency in a child with Prader-Willi-syndrome. METHODOLOGY A 2-year-old male child with Prader-Willi syndrome was assessed for foot posture index by foot posture index scale and gait efficiency by six minutes’ walk test. Short foot exercise was given for 3 sessions per 4 weeks. Following the interventions after 4 weeks, the post-test was assessed by same tool as in pre-test. RESULT After four weeks of intervention, the FPI-6 score was improved from 8 to 7, indicating a onepoint improvement in foot posture. The 6MWT distance was increased from 100 m to 120 m, reflecting a 20 m improvement in walking ability and functional mobility. CONCLUSION The study concluded that short-foot exercises can improve medial longitudinal arch height and enhance gait efficiency in children with Prader-Willi Syndrome.
