Advancements in emerging diagnostic technologies in PM&R are transforming rehabilitation by improving precision in assessment and treatment planning. High-resolution imaging techniques, such as functional MRI and musculoskeletal ultrasound, provide detailed insights into soft tissue and neurological conditions. Wearable biosensors and motion analysis systems enable real-time tracking of patient progress, allowing for early intervention and personalized adjustments. Additionally, artificial intelligence is enhancing diagnostic accuracy by analyzing vast datasets to detect subtle changes in musculoskeletal and neurological function. Genetic and biomarker-based diagnostics are also playing a role in predicting rehabilitation outcomes. These innovations not only improve clinical efficiency but also enhance patient-centered care, leading to more effective recovery strategies and better long-term results.
