Shape Memory Actuators for Medical Rehabilitation and Neuroscience

In the field of medical rehabilitation and neuroscience linear dc actuators have played an important role assisting and boosted major activities.

Neuromuscular Rehabilitation is the discipline and preparation of supporting the recovery of the lost or the impaired motor function, mostly caused by the damage of the central nervous system. Physiotherapy, Pharmacological, and Surgical are the major approaches taken for its treatment. Neuromuscular rehabilitation occurs when its struck primary event is causing server neuronal loss. The immobility and disuse are the functional disruptions mediate the reaction of the primary event.Contracture and utility are conditions that affect the muscles.

Robotics are being implemented in the rehabilitation of the condition because of its advantages on costs and time.

To increase the muscle strength and its capabilities some robotics are designed to provide resisting forces that contract active exercise, machines have been designed that are wearable for this causes.

Robotics have been designed to assist, or even others have proven to take the responsibilities of the impaired motor functions.

In the field of Neuroscience, the scope of the use of the actuators is mainly mandated to provide proprioceptive, kinesthetic or tactile stimulation to enable the investigation of neural responses to the stimuli. Equipment has been invented for neuroscience experiments to be facilitated. SMA actuators, on the other hand, have not yet been embraced fully in this field yet, but for the used SMAs in the field have proved to have an advantage in portability and wearability.

Biomechanical, bioengineering, and clinical specifications are to be looked into before designing an SMA device, and the following specifications should be ready to meet the following specifications the tissues and joints of the patients, the expected loads the interfaces and other factors such as the security.

The design of the SMA actuator takes into account the following stages and factors: Strokes and loads, Power and the Choice of the SMA element.For SMA there are controls to be taken into consideration they are the Assistive control, Gait triggering, Control of passive mobilization cycles
