Wrist Exercise Device

Whom is the device for? (Usage Areas)

Handfizz is an innovative robotic wrist trainer device for two types of areas:

1. For the individuals who want to increase control and strength in their wrist, such as sportsmen & sportswomen.
2. Individuals who have limited mobility (loss of movement) for any reason. For example:

Neurological field:

1. Cerebral Palsy
2. Stroke Paralysis
3. Parkinson
4. Brachial Plexus
5. Head Trauma
6. Spinal Cord Injuries
7. Multiple Sclerosis (MS)

Orthopedic Field:

1. Exercises after bone fracture
2. Tendon injuries
3. Soft tissue injuries
4. Muscle and connective tissue injuries

Handfizz can be used in children and adults if there is wrist movement limitation and spasticity.

How does the wrist strengthener device work?

With robotic wrist exerciser:

1. If strengthening and stretching is required on the wrist, the procedure and the mechanism is different.
2. If active movement is needed, the procedure and the mechanism is different.
3. If exercise is required for spasticity or contraction, the procedures and the mechanism is different.

The mechanism of three different wrist exercises are explained in details below.

1 – In exercises to strengthen the wrist:
The individual connects to the device, the device makes the wrist move up and down, the power range we want the individual to apply in the direction of lowering or lifting is entered into the interface of the device, and when the individual applies more or less force on the wrist than the desired power range, the device gives an audible and visual warning.
This strengthening exercise is an isokinetic exercise. Isotechnotic exercises have been proven to be very effective in strengthening muscles.
During this exercise, the individual has to concentrate on the wrist, power in the desired range when distracted. cannot apply it, the brain has to train the muscles of lowering and lifting the wrist very intensively.
In order to apply force in the desired range, the brain has to give very intense commands to the wrist muscles.
Since the work in the wrist region of the brain will increase, neuroplasticity in that region will increase and the processing capacity of that region will increase.
The wrist will be controlled more quickly by the brain and the muscles there will become stronger.

2 – In exercises aimed at creating active movement in the wrist:
The individual is first connected to the device and it is determined in what range of motion the wrist will work, the device passively makes the wrist move up and down, while the screen shows how much power is applied to raise and lower the wrist. Likewise, when he makes the downward movement with active participation, he sees that he is doing this movement again.

Individuals with weakness in active movement cannot participate in movement in every range of motion, therefore this damaged area in the brain cannot give the body an active movement command. This region, which is supposed to give orders to the brain but cannot give orders due to damage, is exposed to negative neuroplasticity due to not being able to give orders due to not working. While working with the robotic exercise device, the brain has the opportunity to participate in movement at all angles, thus getting the chance to give movement orders to the wrist region at all angles and transforming negative neuroplasticity into positive neuroplasticity. After these exercises, there is an increase in active movement in the wrist.

3 – The Effect of Passive Exercises in Teaching Movement to the Brain:

Thanks to the sensory sensors that transmit position information in the joints and muscles, the brain receives the position information of the body, processes it and orders active movement in this direction.

Especially if damage occurs in the area of ​​the brain that detects the sense of position, the brain orders contraction for protection because it cannot detect the position of the body.

If some of the remaining intact areas of the brain take over the task of this damaged sensory area, the contraction is resolved.

Neuroplasticity [shape changing of the brain] feature is used so that the remaining intact areas can take over the task.

When a lot of position data is sent from the body to the brain, neuroplasticity will accelerate and the regions that remain intact will undertake the task more easily.

Passive exercises are performed on the device by adjusting the desired duration, desired speed and the amount of vibration given to the joint. In this way, there will be a much greater increase in neuroplasticity after the exercise than with manual exercises.

Benefits of Passive Exercises

1. Provides mobility of joints and connective tissue.
2. It minimizes the problem of muscles not being able to complete their range of motion.
3. It protects and supports the elasticity of the muscles.
4. It helps the healing process after injury or surgery.
