Ambulation and Compensations For Balance
Normal ambulation involves the
coordinated effort of the entire body. This involves the
head, trunk and arms as well as the legs. Ambulation has
been described as a series of falls following a period of recovery. This is a learned activity and
requires confidence. It is efficient and appears to be one
continuous motion. In actuality, it is a complex series of
movement patterns. Under routine circumstances, ambulation
is automatic and does not require conscious
thought.
In the presence of special conditions, it
may be necessary to actively think about the act of walking.
A person on the high wire uses compensations involving the whole body in order to maintain balance
and security. The arms may be extended out to the
side as a counterbalance to the decreased base
of support. Walking on ice is another activity that requires
compensations to ensure balance and security. The toddler
learning to walk has a very wide base of support and uses
gross body movements or compensations to avoid falling down.
There is a learning curve that must be mastered before
ambulation can become an unconscious activity. These
counterbalances and gross body movements ultimately give way
to effortless and efficient gait as the individual matures.
Compensations are normal responses to
activities that affect balance and security.
Individuals with physical limitations
must use compensations on a routine basis. These
compensations are evident in movement patterns that can
identify an individual from a distance. Muscle weakness with
associated muscle imbalance, joint deformities and limited
range of motion or surgical fusions are common causes
resulting in a loss of balance. Compensations become an
unconscious habit over time. The repetitive
nature of these movement patterns decreases efficiency and
places a tremendous burden on the body.
Compensations vary in complexity
according to the degree of deficiency and loss of balance.
They range from a single arm movement in one plane to many
movement patterns involving multiple planes of motion.
Instead of all the body parts working in harmony, they move
contrary to the intended direction. The symmetry of gait is
lost. Efficient gait requires the body to continuously move
forward with minimal deviation. Compensations involving the
trunk, pelvis and arms and legs cause gait
deviations. The deviation of these body segments can
be forward or backward, up or down, side to side, rotational
or any combination thereof. The analysis of the complexities
of compensations, their underlying causes and how to
eliminate them is a demanding task.
It is important to understand these
compensations from the point of view of the client as well
as the clinician. Humans are very adaptable. When
compensations become habit, security is achieved at the
expense of efficiency. The patterns of movement utilized in
this effort become as unconscious as "normal ambulation".
All compensations detract from the net force of moving the
body forward. Inertia (momentum) is lost and
rhythm and symmetry is disrupted. It is like driving while
alternately hitting the gas pedal and the brakes. Smooth
acceleration to a "cruising speed" is replaced by a series
of starts and stops. In ambulation, the most energy is
expended in acceleration and deceleration. The pre set
cadence that each individual is endowed with is altered
which decreases the efficiency of the gait cycle even
more.
Approximately 70% of the body
mass is concentrated in the upper body consisting of
the head and trunk. The remaining 30% is distributed between
the lower extremities. In single leg support, 15% of the
body mass is supporting the remaining 85%! In normal
ambulation, this can only be efficient through balance and
inertia as the body moves forward. Compensations that
deviate from this forward progression of the body increase
effort and energy expenditure to extraordinary levels. As
the trunk leans to the side and back while the pelvis
rotates in the process, 70% of the body mass is going
in the wrong direction! The supporting limb may also
be supporting the body mass for longer periods of time as
asymmetry increases. In cases of one-sided involvement, it
is no wonder that the "good leg" presents more problems in
terms of pain and orthopedic problems. If both legs are
involved, the effort will ultimately lead to a sedentary
lifestyle.
With the proper assessment and
appropriate orthotic support system, balance can be
reestablished and eliminate the need for
compensations. The elimination of the habit resulting from these compensations will require conscious
effort on the part of the individual to benefit from the
orthosis. Clients who commit to our techniques and first learn OrthoBalancing™ and then progress to the dynamics of NeuroBalancing™ can exchange old, inefficient habits for new, positive habits. Fixed deformities, contractures or weakness of the
hip musculature will require continued compensations but
these can be minimized.
Solutions for compensations
that affect balance and ambulation are now available.
Recognition of the deficits that ultimately lead to
compensations due to the loss of balance is the critical
first step. Knowing that there are alternatives to
traditional methods of treatment is the next step. Education and understanding can lead to the
goal of improved function rather than accommodating existing deficiencies. Early
detection can avoid the deformities and possible surgeries
that can result from unresolved deficits and compensations.
The sooner treatment is initiated, the better the outcomes. Dynamic Bracing
Solutions™ offers solutions in an innovative approach that treats the deficits directly as opposed
to treating the symptoms caused by compensations. A
truly functional orthotic support system must address the
structural needs of each individual and their related
security issues. It must be dynamic in order
to reestablish balance and eliminate the need for
compensations. This approach offers new hope for the physically challenged individual in dealing with
functional deficiencies.
