Fatigue‐Driven Adaptive Assistance for a Semi‐Active Upper‐Limb Occupational Exoskeleton

Advanced Intelligent Systems, EarlyView.
Physical fatigue during a physical activity is estimated in real time to enable adaptive exoskeleton assistance. By continuously adjusting the level of support according to the user’s fatigue, this approach reduces physical demand and provides a pathway toward personalized exoskeleton assistance.

An Active Knee–Ankle–Foot Orthosis With Torque‐Dense, Low‐Impedance Knee Actuation

Advanced Intelligent Systems, EarlyView.
This article presents the simulation, design, and clinical validation of a robotic active KAFO with torque‐sensitive actuation. By passively and continuously adapting the transmission ratio in response to the knee torque, the torque‐sensitive actuator overcomes the tradeoff between torque, weight, and impedance observed in conventional robot actuators,

Review of articular cartilage repair techniques and their application in the horse

Equine Veterinary Journal, EarlyView.
Abstract Articular cartilage lesions represent a significant career‐limiting problem in athletic horses. A healthy articular cartilage surface is vital for optimal joint function, and defects can result in irreversible degenerative changes. Successful treatment of cartilage lesions remains a long‐standing challenge for orthopaedic surgeons, prompting ...

Expert consensus on neuro‐musculoskeletal functional reconstruction for post‐stroke spastic hemiplegia

Ibrain, EarlyView.
This expert consensus proposes a patient‐centered pathway for functional reconstruction after post‐stroke spastic hemiplegia: “patient goal–pathophysiologic component–treatment target–functional reassessment.” Treatment selection and sequencing across motor retraining, brain–computer interfaces, peripheral nerve surgery, and tendon/soft‐tissue ...
