This invention discloses a text-driven human motion editing method based on comprehensive positive and negative supervised learning, belonging to the fields of artificial intelligence and computer vision. The method comprises two stages: model training and application. In the training stage, the original motion, target motion, and positive and negative text instructions are acquired. After feature extraction and fusion, these are input into a diffusion Transformer model for denoising and prediction. The core lies in simultaneously calculating three losses: retrospective feature supervision, motion preservation, and triple semantic alignment, and jointly optimizing them with the model's main loss to obtain a comprehensively supervised motion editing model. In the application stage, user instructions and the motion to be edited are input into the model, which outputs a target motion that accurately responds to semantics while highly maintaining the coherence of non-edited regions. This invention significantly improves editing accuracy, preservation capability, and generation stability through a multi-layered, positive-negative combined comprehensive supervision mechanism.

Disclosed are devices, systems and methods for inserts for sacroiliac joint arthroplasty, which can include the employment of a longitudinal bone screw and associated threaded cylindrical sleeve, received on a proximal end of the bone screw, with a collet, nut or other securement feature holding the sleeve onto the screw. The sleeve can selectively articulate and / or be immobilized relative to the bone screw, with the system allowing for, at a surgeon's option, motion preservation between bone surfaces in some surgical applications while being utilized as an immobilizing and / or fusion construct between bone surfaces during other surgical applications.
