Synthetic fall data from LLMs helps LSTM fall detectors on low-frequency waist datasets (UMAFall +56.83%) but hurts on high-frequency or wrist datasets; diffusion data matches real data best yet does not reliably improve detection.

AI-Generated Fall Data: Assessing LLMs and Diffusion Model for Wearable Fall Detection
Synthetic fall data from LLMs helps LSTM fall detectors on low-frequency waist datasets (UMAFall +56.83%) but hurts on high-frequency or wrist datasets; diffusion data matches real data best yet does not reliably improve detection.
