Abstract: Many people are living with neurological disorders such as cerebral palsy, stroke, muscular dystrophy or dystonia, that affect the control of upper limb movement. These motor disorders can be involuntary contractions, spasmodic movement or tremors. These disorders limit in the accomplishment of several tasks of daily life. Technical aids can then be used to facilitate movement, to compensate for a lack of muscle tone or to allow the manipulation of objects. In particular, assistive devices are designed for people with upper limb movement disorders to eat autonomously. Several factors limit the use of current assistive devices, such as their high price or high complexity. The aim of this thesis is the development of a new eating aid for people with upper limbs motor disorders. The hypothesis is that the use of the eating assistance developed will improve the ability of people with movement disorders to eat autonomously. This assistance would increase user involvement while reducing the workload of the caregiver. Two assistive prototypes have been developed : a passive version and an active version. The passive version consists of a bar assembly that maintains the constant orientation of the utensil and mechanically dampens involuntary movements. An active version was then developed, where actuators replace the mechanical dampers, in order to offer a more intellignent assistance.
