A bio-stimulation robot includes a stationary platform, a plurality of drive modules coupled to the stationary platform, and a motion platform coupled to the drive modules to operate to change a position of the motion platform. Each of the drive modules includes a first guide member having an arc shape, a motion member coupled to the first guide, and a leg member having a first end coupled to the motion member and a second end fixed to the motion platform. The motion member slides along the first guide member. The second end of the leg member is rotatably connected to the motion platform. The second end of the leg member is rotatably connected to the motion platform.

An electrode is provided that includes a wire that has a wire diameter of between 75 and 125 microns. The electrode includes a non-electrically-insulated current-application longitudinal segment, which, in the absence of any applied forces, is coiled and has (i) an outer coil diameter of between 3 and 7 times the wire diameter, and (ii) an entire longitudinal length of between 5 and 35 mm. The electrode further includes an electrically-insulated lead longitudinal segment, which has an entire longitudinal length of at least 10 mm, in the absence of any applied forces. Other embodiments are also described.

An embodiment in accordance with the present invention is directed to a system and device for applying electrical direct current transcranially to the brain that is combined with a behavioral activity consisting of an isometric force production task. The device is non-invasive or implantable and serves to improve motor symptoms in Parkinson's disease (PD) and other movement disorders. During the stimulation, the patient is engaged in a behavioral task using a system consisting of two force transducers and a controller. The patient holds the transducers, one in each hand, and is engaged in a task that requires the brain to assign forces to each arm so that the sum of the forces matches an instructed amount. In an electrode placement specifically for PD, bilateral primary motor cortices are simultaneously stimulated according to a specific algorithm that depends on the forces that the PD affected individual produces in the behavioral task.
