Kinetic analysis

Possible to use in disorders of standing stability, perception of symmetry, control of the center of gravity, training of controlled loading of the feet in a closed chain, active stabilization of the body sitting / standing.

Treadmill with built-in force platform (C-mill, Zebris)

Disorders of standing stability, perception of symmetry, control of the center of gravity, training of controlled loading of the feet in a closed chain, active stabilization of the body sitting / standing.

The device consists of a plate with built-in strain gauges (piezoelectric) sensors, which generate a voltage created by a force acting on the surface of the plate.

They allow an analyze the distribution of pressures acting during the contact of the foot with the pad - color map / 3D. The treadmill on the force platform allows walking / running at a set constant speed, which can be recorded on video cameras. The size of the vertical component of the reaction force of the substrate is important. The course of the force curve can distinguish abnormalities during the execution of the step cycle and shows changes depending on the change of speed.

The vertical component of the reaction force of the surface normally has a two-peak course (see the figure dynamic analysis of Stance phase"

At the time of initial contact, the applied force Fz increases, which reaches a peak in the phase when the standing lower limb takes over the weight of the whole body - decreases during the middle standing phase (load is compensated by slight flexion of the knee joint) - by activating plantar flexors the second peak occurs lower limb) - decrease of force in the phase of double support - zero force when detaching the foot from the surface.

The treadmills can also evaluate the change in the position of the COP - on stationary force platforms it has a wavy trajectory, on the force platforms below the treadmill - a butterfly.

Therapy:

 Influencing the spatiotemporal characteristics of walking - projection of tracks on a treadmill or screen - clarification of the patient's ability to modify walking

Adaptability training (Virtual training) - training in a virtual environment teaching the patient to avoid obstacles, modify the length and width of the step
