The Harmony Prosthetics Leg by Otto Bock – Product Review

Artificial limbs that are used in cases of amputation are knows as prosthetics limbs. While you can use crutches or wheelchairs, it is always better to opt for prosthetics leg as it offers better gaits, better sense of independence and a better-psychological point of view towards life.

The Otto Bock way

If you are facing amputation, Otto Bock’s Harmony prosthetics leg is your best bet for any below knee level systems. Otto Bock has combined two of the best prosthetics systems- the Triton carbon fiber foot and the Harmony volume management system. The Harmony system improves the connection with your leg so that you can walk with improved speed and also ensures security. The Triton foot, on the other hand, has a functional ring that helps in managing any bumps and obstructions you may find on your way.

Coping with the initial problems

Very often it so happens that your leg may feel loosely connected to your prosthesis. This happens because of the volume changes in your sockets. There are some conventional weigh bearing sockets that causes this fluctuation in the fluid level and can even force fluids to come out of the limb while creating a disturbance in pressures. This can over the course of time, cause skin problems and block your activities. But you will not be facing these problems with the Harmony Prosthetics leg which is designed in a special way.

The role of TSWB

Otto Bock has created a TSWB (Total Surface Wight Bearing Socket) that holds the weight of the whole surface instead of just the edge or the bottom. The liner is made from Polyurethane that distributes pressures in your socket in an even manner. Add to these, the Harmony functional ring. This ring acts like a pump to create the elevated vacuum, thereby supplying shock absorption and can even twist like a real angle while you are loading. Lastly, there is a three carbon fiber springs which give you a wonderfully smooth rollover. Along with these, comes the adjustable heel that has the shock absorbing property too. As you can see, the Harmony Triton Elevated Vacuum system includes a TSWB socket, the Anatomic 3D PUR liner, the Harmony functional ring and the Triton carbon fiber foot. The whole package reduces the risk of any fluid loss, and you can only relish the wonderful comfort as you walk.

Advantages revisited

The advantages of using a Harmony Prosthetics Leg are manifold, as you can already understand:

  • You can walk easily on a rough surface.
  • You can maintain balance both when you walk and stand.
  • You can walk very naturally
  • The linkage will help you feel where your leg is in space (proprioception). This helps in more confident ambulating.
  • Reduces fluctuations in residual limb volume so that you don’t need to add spots and socks throughout the day.
  • Reduces forces in the socket.

Hence, amputees need not wait any further to get back their strength of limbs. One can order Harmony Prosthetic Legs now and enjoy the benefits of smooth walking again with content and satisfaction.

Why Use Prosthetic Contact Lenses

Prosthetic contact lenses have more than one use. They are not just used for helping correct the looks of a person with defective or discolored eye, but also help people with vision glare problems and children with amblyopia.

One of the basic uses of the prosthetic contacts is for correction of looks. People with eye defects due to birth, or some disease, or maybe due to some injury or accident; often feels embarrassed with their looks in public. While one eye looks natural the other eye’s retina may have a color difference, or total disfiguration. Not only does that create a distorted look, but sometimes it may give a scary look too, which any person would not want to look like. Hence, the role of prosthetic contact lenses gets quite loud in such cosmetic corrections.

Besides the prosthetic contacts also helps in vision correction while correcting the cosmetic looks. There are various types of prosthetics for eyes, and they are broadly distinguished as vision corrective prosthetic contacts and cosmetic prosthetics for eye.

Cosmetic prosthetics for eye

The cosmetic prosthetics are used simply to camouflage the defective eye, so that the person looks normal, and the defect stays hidden to others. These prosthetics can be custom made and colored accordingly so that the lens matches the color of the other healthy eye.

Sometimes prosthetic contact lenses are also used to block excess light from entering the eyes, in case it’s used for patients with a problem of getting glare in daylight in their eyes.

Prosthetic contact lenses for vision correction

There are people who have both the problem- a defected external look, and vision problem, or one healthy eye which needs vision correction, and the other eye, which needs cosmetic correction. In such cases, cosmetic and vision corrective prosthetics offers great service. These can be used to make the eyes looks natural as well as give them the corrected vision.

There are children with certain birth defect of vision, and this defect is known as amblyopia. The amblyopic eye needs to be kept open through the day so that it exerts more pressure on the eyeballs, and vision can develop. The other healthy eye in those cases can be covered either with a cotton or eye block or prosthetic contacts. The advantage of blocking the healthy eye for a few hours per day, with prosthetic lenses, is that, it causes no embarrassment to the kid who may be going to school, playing outside and getting social. Moreover, the prosthetic lenses blocks sight and sun rays totally and help the amblyopic eye get well soon.

Types of prosthetic contact lenses and lens care

Just like normal contact lenses, prosthetic contact lenses are available in variations too, and there are gas permeable prosthetic, soft lenses, and semi-soft lenses. The lens care is pretty normal, and can be done with products and solutions that you find in a shop for other normal corrective vision and cosmetic contact lenses. Buying both lens care items and prosthetic contact lenses is quite easy with trustworthy online shops featuring prosthetic contacts.

Prosthetics For All Purposes Covering Internal And External Organs And Parts

Humans have been trying their best to live a better life ever since they got civilized, and the introduction of prosthetic body parts and experimenting on making them as good as possible is just another step taken by man to make life better. It’s a globally accepted initiative for the betterment of life even if one goes handicapped. Handicapping is something that actually stops the flow of life and diverts life off mainstream. But when you are equipped with prosthetic body parts to aid in movement which you lost due to the accident, birth defect, disease or some amputation, then you can gradually get back to the mainstream of life, and lead life with a new zeal.

All sorts of prosthetics

Prosthetic arms, legs and even heart valves are available today, and these items are made with the use of the most-recent technologies, and their development is not stagnant. The parts manufactured in different parts of the world, are constantly upgraded in quality and technology, while making them more usable. The main objective of the developers and scientists is to incorporate physiology with mechanics, and then to add cosmetology to it to create products which would not only just work great when joined to the amputated human body area, but would also look like and feel like a real body part.

Naturally looking high-quality parts

To achieve this, the parts are made as naturally looking as possible. The skin tone and even age lines and human body hair, etc. are all added to the parts to make them look real- so real that one seeing them would hardly be able to distinguish between the two. The user of the prosthetics would also feel good as they will be able to face society with much confidence.

Extreme care is taken to make sure that the best materials make entry to the human body. Since, these materials are even fitted on the heart as prosthetic heart valves are also fitted on other body parts and for the whole lifetime, hence it’s very important that the materials are 100 % safe, and never decays or breaks down with time. Or else the body would get highly affected, especially the internal body organs.

Types of prosthetics

Prosthetics are both motorized and automatic. The motorized prosthetics are externally controlled and dependent on the other healthy body parts to get controlled through buttons, etc. However, the electronic or automatic parts are not so. The electronic prosthetics are designed to attach to the body with electrodes while following the body signals via neural electric waves. Naturally the myoelectric parts are internally controlled and are priced higher than the motorized parts, and functionality and features also differs somewhat.

Prices vary

Both types- the externally operated and internally operated parts are equally popular among men, the reason being the price variation. Naturally the internally operated parts, which are fully computerized are priced high, whereas the motorized parts that are externally controlled are priced low. Due to this variation, people choose the parts as per their budget. However, there are parts for almost all needs in the current day, and the future of prosthetic inventions looks quite promising.

Most Common Prosthetic Parts and Their Uses

Prosthesis refers to an artificial substitution of a body part like tooth, bone, joint or leg that is lost due to some kind of accident, injury or is damaged from birth. The device that replaces the damaged body part is called prosthetic. With the increasing development of medical science, the use of prosthetic has become much common, and physicians popularly recommend them as a way of improving the quality of life. Some people with a lost limb feel that the most-important trait of prosthesis is that it looks very much like their lost limb. Use of prosthetics not only helps in smoothens the progress of daily activities but can also give a better-psychological outlook towards life. People with prosthetics can feel less uneasiness in a crowd because they find it easier to be at one with other people.

To provide a little more information, listed below are some common types of prosthetic used widely:

Limb prosthetics: 

These prosthetic are used to replace injured or damaged upper or lower limbs.

The Upper extremity prostheses are used at different stages of amputation. Some examples are shoulder, elbow, wrist, full hand, partial hand, finger dislocation. There are also prosthetic that replaces the whole arm from the elbow. These are called Transhumeral prosthetic. The Transradial prosthetics, on the other hand, are used for an arm missing below the elbow.

A transfemoral prosthesis is an artificial limb that restores a leg missing above the knee. These amputees generally have a very hard time to walk again normally.There is also the   transtibial prosthetics which replaces a leg absent below the knee. Such amputees are usually able to walk normally faster than someone with a transfemoral prosthetic, because they retain the knee that helps a lot in free movement.

Facial Prosthetics:

A facial prosthetic is an artificial device used to alter or adapt the external look of a person’s face or head. These are generally used in the theatre or film industry and made from materials like latex, foam latex and silicone. The Pros-Aide and BetaBond are very popular facial adhesives that can be used for slight changes like altering the curve of the nose or for creating wrinkles or making someone look younger. These facial prosthetic are also used to create an extra-terrestrial or bestial appearance. The advantage is that these facial prosthetic do not cause any kinds of allergies or skin irritation. After it is applied, cosmetics are used to colour the prosthetics, to give it a natural look. On the screen, it does not even look like a prosthetic is used. There are prosthetics that can simply be pulled off after use; others need special water-based or medical removers.

Internal Prosthetics:

It is a device implanted during an operation into the body as a way of providing internal support or to replace internal parts of the body. These can be bone prostheses for suffering from bone cancer,  dental implants, artificial hips, knees, or other joints, heart valves, urinary bladder or hymen. Hearing aids can also be included in this category.

How Prosthetic Parts Work In The Human Body

Prosthetics have come up a long way in improvement and advancement, and now the modern day prosthetics can compete with the healthy limbs quite sportingly while listening to the muscles and nerve signals of the body. However, the journey has not been an easy one, nor even one, and was interfered a lot of times with failures, confusions, problems, etc. In the current day, the scientists have come up with great discoveries and innovative techniques, making prosthetic limbs real good give the amputees a great life.

Workings in the earlier days of development

The working of the prosthetics in the old days were purely mechanical, and difficult, when there were buttons and switches only to control the parts, and the users had to use them. The buttons had to be toggled on and off with the other healthy limb in case of the upper body prosthetic. In the case of a lower body prosthetic, the movement could be a little easy making walking and movement relatively easier than the arms.

In short prosthetic limbs can be categorized in two major segments. They are the externally controlled prosthetics and the internally controlled prosthetics.

Externally controlled prosthetic limbs

Since the electronic limbs are extremely high priced, and not affordable for all people from all backgrounds, the motorized manual prosthetics are still in use and in fact quite widely in use globally. The motor operated prosthetics are controlled simply by switches. The switches and position and adjusted manually with the help of the other healthy limb or shoulder. Often in the case of the upper body prosthetic, the limb is joined to the body by strapping it to a healthy shoulder or arm. This makes the muscles of the healthy shoulder to control the switches with movements and gestures.

Internally powered or electronic prosthetics

Another way to control prosthetic limbs, which are not externally powered, but rather internally powered by the body, is by the body’s own signals. The human body muscles move through nerve signals. These nerve signals are given by the brain to the body parts through nerves. These neural signals pass as tiny waves of electricity, and these electric signals are the key to the body’s wish and the instructions of the brain. These electric waves are caught and processed by the computerized modern day prosthetics to convert the signals to movements.

The electronic parts are commonly called myoelectric. After a leg or arm or other body part is amputated, there are parts of nerves that remains at that part in the remaining muscles. These muscles still gets nerve signals from the brain through those nerves in the form of electric waves, and these electric waves are caught on electrodes. The myoelectric parts are connected to the amputated part using electrodes, and then the muscles with their movement, and the nerve signals control the parts.

Availability of the products

The importance of prosthetics will always be there for the amputated, and to make the prosthetics affordable, there are several online shops, which have come up with an affordable range of products. The electronic ones sill stands out as costlier options, but when it comes to functionality and ease of use they are also chosen  by people who can really afford those.
