Security Issues

Security issues are concerns about safety. They involve activities or movements that elicit fear. We don't want to get hurt. In the case of physically challenged individuals, the fear is usually of falling. Security Issues are based on actual events and justifiable concerns. An example of a security issue for anyone is walking on ice. One discovers quickly that they must alter their walking strategy. It may be based on a previous experience or the mere fact of losing control without actually falling. One soon learns to alter their walking strategies. Most people will crouch down a little and spread their feet out. This lowers the center of gravity and increases the foundation. The concentration required for movement is intense and becomes the primary focus of attention. Shorter steps or even shuffling the feet without lifting them is safer. Arms are spread out to help with balance. All these compensations are made to reduce the security risk. If these strategies don't work, it may be necessary to get down on all fours and crawl to safety.

It is human nature to make compensations for security reasons. Security issues can become a routine part of daily life. This may happen gradually over time. Each falling episode has a cumulative effect. Ultimately ambulation becomes a conscious effort. Normal ambulation is an unconscious activity. Security issues can make ambulation a conscious activity. This creates compensations, balance problems and a lack of efficiency. Until the security issues have been solved, compensations will be made. In the case of a typical individual on ice, the security issues are eliminated upon reaching dry ground. For the individual with physical limitations, security issues become ingrained in the subconscious mind; in other words, the compensations become normal in spite of the lack of efficiency. Understanding that they exist, recognizing and understanding their purpose and providing a solution will return security and efficiency to near normal levels.

Security issues causing compensations are learned activities. They ultimately become habits. Each person demonstrates unique characteristics and degree of severity. The most common examples of security issues in gait are decreased standing and walking balance, tripping over the feet, ankles rolling over and for some, knees buckling.

Difficulty with balance is one of the most common security issues with people with physical limitations. This is caused by a combination of weak muscles and progressive deformities in the foot and ankle complex; in addition, balance is normally maintained by a complex array of neuro sensors and muscles. This is called proprioception. Proprioception can be defined as the awareness of the body in space or the awareness of the position of a body part without visual cues. As the body leans too far, sensors send messages to activate muscles to oppose that movement and return to the original upright position. For some people, the sensors and muscles that provide proprioception may not be working properly. Instead of small activation of a few muscles to maintain standing in one place, the individual with limitations often has to take quick steps to catch and right themselves.

Tripping or the loss of balance heightens the awareness of security issues and the fear of falling. The most common compensation is to lift the whole leg high enough to clear the foot that is dropping. As weakness progresses, the leg must be lifted higher. This compensation is called high steppage gait. One must lift 15% of one's body weight straight up against gravity on each step. This involves increased energy expenditure and creates balance problems.

The ankle rolling over also affects balance and the fear of falling to one's side unexpectedly. This is caused by deformities from an imbalance of muscles. Certain nerves are affected more than others, thus affecting the precious balance of muscle strength. Some people tend to have more of a discrepancy that causes excessively high arches called pes cavus. As the deformity increases, the ankle is very susceptible to rolling over to the outside. Falls, ankle sprains, and even fractures are all quite possible and common. The compensations are spreading the feet, slowing down, shorter steps, quicker steps and no longer shifting one's body weight over the feet. Ultimately, balance becomes impossible.

Others may have the opposite and have fallen arches or Pes Planus. Balance also decreases as the foot collapses further and further. Energy consumption increases to solve the security issues.

The buckling of the knees is common and creates a major security issue. To prevent the likelihood of knees buckling, one will start snapping their knees backwards on each step. This creates hyperextension at the knee. (also called recurvatum) This repetitive compensation in time stretches the structures on the back of the knees. The structures involve ligaments, tendons, joint capsules, nerves and blood vessels. The recurvatum is classified as mild, moderate and severe and will progress if not prevented. Pain can also be associated with recurvatum. To be secure, one rapidly moves 15% of their body weight 180 degrees away from the intended forward direction. A secondary compensation often associated with recurvatum is the forward movement of the upper body over the weight bearing leg during stance. Before a step can be taken on the other side, the trunk must move backward and to the opposite side. Since the trunk comprises 70% of the body weight, this constant and repetitive movement increases effort and energy expenditure tremendously! The body is literally moving in opposite directions at the same time! This is extremely inefficient.

In order to be effective, bracing solutions™ must recognize and address all security issues. This includes structural and functional deficits in addition to the compensations and their causes that are unique to the individual. Deviations and habits caused by security issues must be solved in order to achieve balance and efficiency.

Remodeling is a straightening process of tight structures or fixed deformities. Surgery is the most common method of straightening fixed or rigid deformities. Another process utilized is called serial casting. A series of non-weight bearing casts can make progress in short term goals. The Remodeling process can replace or be used in conjunction with the other methods. Surgery and serial casting may only get limited correction. Remodeling can continue where serial casting leaves off. The advantages of the remodeling process are many. There is no down time, a person can continue walking and living their life during the corrective process. We believe, it is the best method to obtain maximum correction. Remodeling has the advantage of time and pressure. Corrections once thought unobtainable are now common with this method. The more correction gained by the Remodeling process the more security, balance and efficiency as well as improvement of weight distribution on one's feet. As anatomical positioning improves the mechanics for efficient and secure ambulation is possible. This allows for the restoration of proper movement patterns that ultimately leads to optimal efficiency and a return of a more normalized gait. Security issues for people with fixed deformities often limits ambulation. The foot no longer has a quality base of support. The foot endures high pressure on the limited surface area touching the ground. Balancing on such a foot or leg is difficult. Compensations required for security and balance is often too taxing on the metabolic rate and efficiency.

Remodeling can improve security with improved alignment. Return more efficient ambulation to those who have all but stopped walking or improve ambulation to those that may be slowly losing the ability to walk with a secure and efficient gait.

Efficiency is defined as productive with minimal effort or capable. The underlying goal of DynamicBracingSolutions™ is to allow movement in the most efficient manner. Solving all the complex issues in each of the three planes throughout the gait cycle and preventing further deformities, translates into efficiency. Ambulation is fundamental trait of human beings. It is an unconscious activity that is often "taken for granted." Gait can only be an unconscious activity if it is optimally efficient. The desire to ambulate is based upon this notion. Insecurity and fear leading to compensations and balance problems diminish the desire to ambulate.

We believe at DynamicBracingSolutions™, that new possibilities have been recognized and have developed the technology in order to deal with complex pathomechanical profiles. Outcomes once thought unobtainable are now possible.

Do we have secure solutions people with physical limitations? In most cases, the answer is absolutely yes! We believe there are no other braces that can compare to our dynamic remodeling orthotic systems or the dynamic response triplanar control solutions for a more efficient and secure solution. It is our commitment to individualized solutions that makes us unique in the orthotic profession.
