Introduction: Developmental delay, particularly in gross motor skills, affects approximately 10% of children globally. In Ayurveda, this is conceptualized as Phakka Roga, a condition characterized by the inability of a child to walk independently by one year of age, accompanied by systemic physical wasting. Material and Method: This conceptual review was carried out based on classical Ayurvedic literature and modern paediatric references. The primary source for the study was Kashyapa Samhita (Chikitsa Sthana, Phakka Roga Chikitsa Adhyaya), which was critically analysed to understand the aetiology, clinical manifestations, and management of the three types of Phakka, namely Ksheeraja, Garbhaja, and Vyadhija. Relevant data regarding the etiological factors, symptomatology, and therapeutic principles were compiled, analysed, and correlated with contemporary paediatric concepts for better clinical understanding. Result: Phakka Roga manifests as severe muscle wasting (Ksheena-mamsa) and abdominal distension (Mahodara) due to Mandagni and Srotorodha, which impair tissue nourishment from Rasa Dhatu. Management is cause-specific: digestive stimulation (Deepaneeya) for Ksheeraja; anabolic therapy (Vidari, Ghrita) for Garbhaja; and primary disease management followed by rejuvenation with Samvardhana Ghrita for Vyadhija. The Phakka-Ratha (Specifically designed walker) provide early evidence of structured physical therapy. Discussion: The study reveals that Phakka is an umbrella term use for metabolic and nutritional disorder caused by various reasons. By integrating internal purification (Shodhana) with targeted nutrition and mechanical aids, Ayurveda offers a holistic framework for treating developmental delays. Conclusion: Early intervention using Samvardhana Ghrita and the Phakka-Ratha can effectively reverse motor delays and restore tissue integrity, highlighting the relevance of ancient paediatric protocols in modern nutritional rehabilitation.
