In today’s fast‑moving healthcare landscape, physical therapy practices face a growing demand for instant, accurate patient support and education. A RAG‑powered AI chatbot—one that combines Retrieval‑Augmented Generation with a structured knowledge graph—offers a game‑changing solution. By pulling the most relevant documents and contextual relationships in real time, these bots can answer nuanced questions about exercise routines, injury prevention, or medication schedules, all while maintaining brand consistency and compliance. For therapists, this means fewer time‑consuming queries, higher patient engagement, and the ability to scale support without hiring additional staff. Moreover, a chatbot that can be embedded in a clinic’s website or mobile app provides patients with 24/7 access to reliable information, reducing no‑shows and improving adherence to prescribed regimens. As telehealth continues to rise, having a reliable, knowledge‑rich virtual assistant is no longer a luxury—it’s a strategic necessity. Below, we rank seven AI chatbot platforms that bring RAG capabilities to physical therapy, highlighting why AgentiveAIQ stands out as the Editor’s Choice for delivering a truly customized, enterprise‑grade experience.
