Stroke is a common condition that affects the brain and can cause weakness or paralysis in one side of the body. Rehabilitation is crucial to help regain mobility and function, and robotic hands are becoming an important tool in this process. The article reviews the Pisa/IIT Soft-Hand Pro (SHP), a robotic hand designed specifically for stroke rehabilitation.
The SHP is made up of 19 movable parts, which gives it a high level of flexibility and mimics the way the human hand works. The hand can perform various tasks such as grasping objects, manipulating them, and adapting its movement to fit different shapes or sizes. Its soft structure allows for secure gripping and minimizes cognitive effort required from the user.
The SHP integrates a DC motor that controls its movements and a custom electronic board for control. It has been found to be effective in improving hand function in stroke survivors, especially during the initial three months after the stroke (sub-acute phase). This is because the brain is most receptive to change during this time and can reorganize itself to accommodate new movements.
The article highlights several advantages of the SHP. Firstly, it requires minimal effort from the user, which makes therapy sessions more enjoyable and longer-lasting. Secondly, the on-off control strategy used in the SHP is considered effective as it allows for repeated practice of a single task to improve function.
In summary, the Pisa/IIT Soft-Hand Pro (SHP) is a robotic hand designed specifically for stroke rehabilitation. Its high level of flexibility, mimicking of human hand movement, and minimized cognitive effort make it an excellent tool in improving hand function in stroke survivors. The SHP has been found to be effective during the sub-acute phase of stroke, where the brain is most receptive to change. Its advantages include minimal effort required from the user and an on-off control strategy that allows for repeated practice.
