What is your doctor's EXACT STROKE PROTOCOLS to recover your wrist?
Doesn't have any? Then you don't have a functioning stroke doctor.

blockage (ischemic stroke) or a blood vessel rupture (hemorrhagic stroke) that prevents
him or her from performing activities that other healthy people can do. Stroke victims
typically experience paralysis with one of their arms, lose dexterity and interaction with
their affected hand. However, most wrist rehabilitation devices are still manually operated
and required a therapist to assist them. Furthermore, the increasing number of stroke
patients among the elderly are challenging to find low-cost rehabilitation tools. In order to
overcome this problem, a wrist joint rehabilitation device with servo motor drive is
developed. This device consists of three MG996R servo motors using predefined Arduino
IDE programming so that the device start rotating automatically and the patient can
perform their rehabilitation sessions individually. The designing process of this device is
done by using an online 3D modeling program, Tinkercad. The MG996R servo motor was
physically modeled, and the parameters were identified during the implementation of the
device. Testing of the hardware and software was undertaken to analyze the usability of
the wrist joint rehabilitation for the stroke patients undergo the rehabilitation exercise
according to the basic movement of wrist by comparing the normal ROM of the wrist and
achieved ROM of the device can be delivered. As a result, the prototype design has
proven to be effective because it can achieve a ROM that close to the normal wrist. It can
be concluded that an automatic wrist rehabilitation device can be used to assist post-
stroke patients in their rehabilitation sessions by performing regular wrist exercises.

Abstract
A stroke begins when the blood flow to the brain is stopped or diminished because of ablockage (ischemic stroke) or a blood vessel rupture (hemorrhagic stroke) that prevents
him or her from performing activities that other healthy people can do. Stroke victims
typically experience paralysis with one of their arms, lose dexterity and interaction with
their affected hand. However, most wrist rehabilitation devices are still manually operated
and required a therapist to assist them. Furthermore, the increasing number of stroke
patients among the elderly are challenging to find low-cost rehabilitation tools. In order to
overcome this problem, a wrist joint rehabilitation device with servo motor drive is
developed. This device consists of three MG996R servo motors using predefined Arduino
IDE programming so that the device start rotating automatically and the patient can
perform their rehabilitation sessions individually. The designing process of this device is
done by using an online 3D modeling program, Tinkercad. The MG996R servo motor was
physically modeled, and the parameters were identified during the implementation of the
device. Testing of the hardware and software was undertaken to analyze the usability of
the wrist joint rehabilitation for the stroke patients undergo the rehabilitation exercise
according to the basic movement of wrist by comparing the normal ROM of the wrist and
achieved ROM of the device can be delivered. As a result, the prototype design has
proven to be effective because it can achieve a ROM that close to the normal wrist. It can
be concluded that an automatic wrist rehabilitation device can be used to assist post-
stroke patients in their rehabilitation sessions by performing regular wrist exercises.
