Computer gait diagnostics for people with hips implants

in Analysis


The whole diagnostics process should consist of the mathematics, clinic, quantity and

subject analysis. The object movement can be described with use of parameters such as:

angle, velocity and acceleration of the time function. It can also cause the change of the

kinematics of the whole bone and muscle scheme of the patient after implanting. The tools

analyzing the movement of the patient should include the analysis of the whole scheme and

not its separate parts.

In cases when the hip joint is somehow damaged, it automatically leads to impaired

movement of the previously mentioned parts of the body. The rounded head of the thigh

bone is perfectly centered inside (the hip socket / acetabulum).

The hip joint is composed of two parts – the hip socket (acetabulum) and the head of the

thigh bone (femur). (Fig 1). The surfaces of these bones within the joint are covered with a

layer of cartilage. This important surface Cartilage works like a natural shock absorber.

Degeneration of the hip joint as well as different kinds of diseases are caused by a variety

of diverse factors. Some of the reasons for the occurrence - obesity - chronic and excessive

load of joints (especially spine and lower extremities / lower limbs) causes cartilage to begin

to show physical signs of wear and tear particularly in knee joint - repeated loading

(standing, sitting) or the lack of movement - unbalanced diet – a lack of vitamin D3 and

antioxidants (vitamins A, C, B6) - genetic factors : (arthrosis / degenerative affection of

joints) - mechanical insults to the joint from an acute injury (sprain, dislocation) as well as

microdamages Professional sportsmen are especially at risk of arthrosis of a hip, knee,

shoulder. They make up a higher proportion of the total population. It is quite common that

despite the natural factors that cause joint damages there are random factors such as

injuries that can occur after car accidents or bone fractures.


The whole diagnostics process should consist of the mathematics, clinic, quantity and

subject analysis. The object movement can be described with a use of parameters such as:

angle, velocity and acceleration of the time function. It can also cause the change of the

kinematics of the whole bone and muscle scheme of the patient after implanting. The tools

analyzing the movement of the patient should include the analysis of the whole scheme and

not its separate parts.For diagnosis and analysis of a range movement and analysis of walk

are used: - Clinic analysis – consists of medical examination and visual diagnosis by an

orthopedist - Quantity and subject analysis – doing quantity and subject analysis leads us to

many more or less advanced systems. Present researches were done with Vicon help /

using Vicon and Poligon programme.

 

Within the scope of diagnostics:  speed, length and frequency of steps - The dynamic

Investigations – in case of dynamic investigations it consists of Electromyography EMG -

Measurement of muscles electrical activity, measurement of reaction force to foot – Ground

reaction force vector  Next system of quantitative analysis and objected is Sybar. It is an

integrated Mathematical analysis- in case of mathematical analysis the systems consist of

information processed with individual measures, by some from measurement systems - The

static investigations - in case of static investigations it consists of the measurements of

angles, range of movement, speed of steps.
