What is diabetic foot neuropathy

Medi-Rehatek will introduce what the performance of diabetic foot neuropathy is.

Neuropathy mainly is as follows:

(1) Abnormal feeling, such as numbness, acupuncture-like pain, burning sensation and sensory hypersensitivity, especially at night;

(2) Feeling is weakened or lost, there is no feeling for such as cuts, burns, worn, blisters and so.

How to determine your own diabetic foot vascular disease?

Press your fingers on the foot artery of instep to test the pulse beating. If the beating is obvious, indicating the normal blood flow, on the contrary, if the beating is not obvious, or even very weak, indicating that local vascular obstruction may occur, it may occur diabetic foot disease, you should be vigilant.

Occurrence of intermittent claudication, is also important tips.

Patients should promptly go to hospital to have vascular ultrasound check, and havetimely treatment.

Why diabetic foot is difficult to heal

Today Medi-Rehatek will discuss why diabetic foot is difficult to heal.

(1) Due to long-term chronic damage, Diabetic patients will have peripheral vascular occlusion and poor neurotrophy.

(2) The majority of patients’ feelings are weakened or disappeared, often the wound is difficult to detect, once the doctor find out that the situation has been more serious, such as local necrosis, severe infections etc..

(3) The foot is the most distal body with poor blood transport capacity.

Therefore, diabetic foot patients once have foot ulceration, wound healing is more difficult.

What are the symptoms of intermittent claudication in diabetic foot patients?

Diabetic foot patients will feel the pain on the foot and not stand the pain after walking a very short distance. After having a rest,patients are able to ease and can continue to walk. But patients continue to walk again, pain will exist again,then stop and rest. So stop-and-go, patients can not walk as long as normal people walk ,that is known as intermittent claudication.

How to prevent diabetic foot

How to prevent diabetic foot?

(1)Quit smoking.

(2)Control of blood sugar.

(3)Daily check whether skin of foot and lower extremities has swelling and damage.

(4) Daily clean feet with soap and warm water.

(5) The right way of trimming nails: The front nail should be trimmed, but do not over-pruning.

(6) Select the appropriate shoes and socks, carefully check whether the foreign bodyin the shoes before wearing.

(7) Early and regular reports to the doctor of foot problems, if you happen to find foot trauma or infection, should go to hospital as soon as possible.

MEDI-REHATEK has a comprehensive explanation of diabetic foot disease

How to conduct routine foot examination for the high-risk groups of diabetic foot.

It mainly includes the following three aspects:

(1) Check the site: foot, sole of foot,toes, toenails, toe tip,gap between toes, especially the deformation parts.

(2) Check the content: careful observation of the feet with or without skin damage, blisters, chap, redness, corns or calluses, small wounds, etc., with particular attention to the swelling, deformation between toes. Skin temperature is too cold or overheating, dorsal artery pulse is normal and so on.

(3) inspection methods: observation with a mirror, self-examination or ask family members to help check.

Precautions for Children Prosthesis Assembly

Children amputation is a very sad thing, because children are young, physical and mental development is not yet mature, the installation of artificial limbs reduces the obstruction level  to physical and mental development. Therefore, the installation of children prosthesis should be exceptionally careful. 

Today MEDI-REHATEK will talk about what will matter when the assembly of children prosthesis.

1.Upper limb amputation of children

Especially double upper limb amputation, and children should early wear hooked prosthetic hand to have self-rehabilitation and learning ability. Or the children will not only have stunted growth, and will but also have poor intellectual development.

2.Lower limb amputation of children

During prosthesis assembly and application, we must consider the developmental results: the development of the residual limb is slower than the healthy limb. The proper length of the prosthesis will be a lot shorter in six months or a year later.So we need to choose the prosthesis with structure who can be facilitated the transformation of the length.We can make the prosthesis longer.Put the foot pad on the healthy limb and make it temporarily higher, in the future we can removed the pad after the healthy leg increases the length.

3.3. Below-knee amputation of children

We should pay attention to its residual limb bone whose development is faster than the residual limb skin.Sometimes the bone breaks the skin, the external bone develops faster than the internal bone on the stump, which is more likely to cause the projection skin damage or piercing .In case of the situation, children should push or pull the residual limb skin to make the skin become longer and loose.It postpones the time of re-amputation surgery.We also pay attention correct alignment on the device.

The high end artificial limbs

Many new patients will ask MEDI-REHATEK to recommend several prostheses to them, in general cases we will recommend more high-end prosthetic to patients, because the compensation function of high-end prosthetic is better. However, not all high-end prostheses are more practical, because each patient's condition is different, the adaptation of prosthesis is different.In general, the prosthesis issuitable for their own requirements that are the best prostheses. 

We need to consider all aspects of factors when assembling prostheses. We should act responsibly to choose appropriate prosthesis in accordance with the patient's condition. Today, MEDI-REHATEK mainly  introduces the classification of prosthetic grades, so patients can select the appropriate prosthesis according to their own situation.

1, Low-end prosthesis

The low end prosthesis is the cheapest, more made from traditional parts and leather, wood, aluminum prosthetic socket. A number of popular prostheses designed for poor areas which are also low-grade prostheses, which are still used by most low-income groups.

2, Middle-end prosthesis

The price of middle-end prosthesis is reasonable.The parts and raw materials for producing bones and prostheses which are developed or imitated in China. Prosthetic socket assembly and alignment technology adopt modern prosthetic assemblyprocess which is suitable for the honorary soldiers and the injured patients. Such as electric hands, domestic parts like bone prostheses.

3, High-grade prostheses

It is suitable for families with better economic conditions.Its main components are mostly made of new materials, such as titanium alloy, carbon fiber composite materials with high strength and light weight; structure using myoelectric,phneumatic, hydraulic and other more complex control device, which are more in line with human biomechanics with good compensation function.

4, Intelligent prostheses

Intelligent prostheses has a relatively wide range of propaganda in recent years. It is the most high-end prosthesis that brings many amputees with gospel. But its R & D technology is high grade and the production process is very complicate.So the price has been very expensive, so its positioning in a class of patients with good economic conditions.Intelligent prosthesis is developed on the basis of high-end prosthesis,its microprocessor with high intelligence.Intelligent prosthesis controls the various stateby itself, is committed to achieving the function of normal human limb.

Intelligent Upper Limb Prosthesis

Medi-Rehatek will continue to introduce the development of the International Intelligent Upper Limb Prosthesis.

We need to restore the limb movement more, therefore, this traditional myoelectric control method can not achieve multi-degree of freedom control of artificial limbs.In addition, the current control method of electromyogram is not consistent with "natural" use of limb. Therefore, the current myoelectric prosthetic exists in long training process andclumsy movements, the heavy burden of the user's spirit. According to statistics,among amputees with myoelectric prosthesis, less than 50% of people are often using their prostheses.

The research and development of an advanced prosthetic control system improve the handling performance of the upper limb prostheses,that offer a multi-functional, intuitive (bionic) manipulated prosthetic system.It not only improves he quality of life and job opportunities for the amputees , but also greatly reduces service cost by the country, enterprises and families.

At present, the research of intelligent prosthetic hand is still at the initial stage, and there is no definite definition of intelligent artificial hand. In summary, the so-called intelligent prosthetic hand, combines microelectronics technology, computer control technology and bio-hospital engineering and sensor technology and a series of high-tech together to produce a bionic hand that imitates feelings and action of the hands. 

Intelligent hand prosthesis has become a comprehensive project of rehabilitation engineering, biological hospital, mechanism, computer, automatic control technology, microelectronic technology, sensor technology, robotics and so on. With the development of new materials and technologies, the research of artificial hand will be improved constantly. The ultimate goal of the intelligent prosthetic hand research is to create the shape that is similar to the human hand and skin, is close to the function of human hand.They have real-time action control of grasp.Intelligent prosthetic hand is a beautiful goal for researchers to carry on the research unremittingly.

International Intelligent Upper Limb Prosthesis

Medi-Rehatek will introduce the development of the International Intelligent Upper Limb Prosthesis.

Upper limb is an important organ of human life and labor, the loss of any part of the amputees will cause physical, life, work, psychological, social difficulties and mental burden. Upper limb prosthesis is used to replace the whole or part of the upper limbIn the field of auxiliary equipment, upper limb prosthesis has special significance.We strive to replace human hand in function and beauty in order to restore a certain self-care ability and ability to work .

As the structure of human upper limb is very fine, the action is extremely delicate, the main movements are controlled directly by the central nervous system, in accordance with the will of individuals to achieve individual or coordinated action, to complete a variety of functions of the input and output system, (Touch, pressure, pain, heat, etc.).

During the development of upper limb prostheses, movements,sophisticated, flexible and accurate movement control are the goal ofconstant pursuit.From the perspective of rehabilitation engineering, in the development of upper limb prostheses, people have always been committed to improving the function, bionic exercise and control methods,reliability. Myoelectricupper limb prosthesis is preferred as the good performance of bionic motion control.

For a long time, people use a variety of advanced technology research to develop of high performance prostheses.At present, the world has a number of prosthetic and robotics companies which develop a multi-functional electromechanical prostheses or components. In recent decades, the myoelectric signal recorded from the limb surface that has been widely used in the control of upper limb prostheses. However, after limb amputation, myoelectric information source is limited. The higher the amputation level is, the less muscle of residual limb is.
