SummaryIn this study, articulated transarticular external skeletal fixators were used to examine the effects of joint immobilisation, twice-daily passive range-of-motion exercises, and voluntary motion on articular cartilage healing and other joint parameters. Abaxial articular cartilage lesions demonstrated superior cartilage healing to axial lesions. Twice-daily passive range of motion exercises failed to improve the quality of articular cartilage repair when compared with joint immobilisation. Voluntary motion resulted in superior articular cartilage repair tissue with maintenance of near normal cartilage architecture, proteoglycan staining, synovial fluid cell counts and specific gravity, and joint range-of-motion.

The Brain

Knowledge of the brain as a body part is ancient. The term encephalos is found in Homer, but cognitive function was not ascribed to its contents. Certain of the Presocratics linked cognitive capacity to the brain. Similar views existed in the Hippocratic writings. For Plato, the brain’s cognitive role is due to its housing the rational soul. Aristotle regarded heart and brain as exerting sovereign control. In the Hellenistic period, the brain was systematically investigated, its cognitive and sensory capacities experimentally verified. Galen, building on this legacy and applying a rigorous experimental methodology, provided overwhelming proof that the brain mediated sensation and voluntary motion.

Accurately aiming and firing a pistol requires a steady hand. While many devices can steady a shooter’s arm or hand by restricting movement or degrees-of-freedom, few devices actively reduce involuntary tremors while allowing larger voluntary aiming movements. This paper details the design and fabrication of an arm exoskeleton that can actively damp arm tremors while allowing voluntary aiming movements. The device allows five degrees-of-freedom and is very lightweight due to its cable-driven architecture and use of carbon fiber composite materials. Tremorous movement is filtered out from voluntary motion, and an adaptive algorithm provides a tremor-cancelling signal to the cable control motors.
